	Transils (Site not responding. Last check: 2007-10-26)
		Transils (also know as transil) are electronic components similar to zener diodes that are designed epspecially to protect electronic circuits against overvoltage peaks.
		Typically the transils is connected between the electrical wire to protect and the ground.
		If the voltage on the protected wire becomes larger than the transils threshold, the transils conducts and and creates a current towards the ground that prevents the voltage increase above the threshold.

		A Transil is an electronic component similar to a Zener diode that is designed especially to protect electronic circuits against overvoltage peaks.
		Transils are avalanche diodes manufactured in the same way as Zener diodes, only are more thoroughly tested to make sure they are capable of withstanding high impulse loads.
		Transils act as clamping devices, suppressing all overvoltages above their breakdown voltage.

		This means that if you accidentally swap the polarity of the battery, the transil will act as a short circuit and trigger the fuse.
		A Zener diode could be used too, but transils are specifically designed to absorb voltage spikes, so they're more suitable for this purpose.
		Like transils, diodes can protect your equipment when you accidentally switch the polarity of the power supply -- which is surprisingly easy under field conditions.

	Transil - Wikipedia, the free encyclopedia
		Uni-directional Transils: that expect an overvoltage of a well known polarity, behaving as a rectifier in the other direction
		Typically the Transil is connected between the electrical wire to protect and the ground.
		Parasitic capacitance: The nonconducting Transil behaves like a capacitor.

	Transils (Site not responding. Last check: 2007-10-26)
		This is a summary of an article on Transils.
		There are two kinds of transils: 'Uni-directional transils': that are expecting overvoltage of a well known polarity, behaving as a rectifier the other direction 'Bi-directional transils': that can handle overvoltage from both directions (they are made by internally connecting two uni-directional transils back-to-back.)
		Transils are characterised by 'Breakdown voltage': the voltage above which the transils* begins to conduct 'Response time': this time must be the smallest possible because otherwise the circuits that need protection will be destroyed before the transils* begins to act as a protection device 'Parasitic capacitance': The non conducting transils* behave like a capacitor.

		With this equipment it is possible to measure the leakage current of a component, as well as to visualize its characteristics I = f(U) (ID, IR/VD, VR tests).
		With these indications it is furthermore possible to better determine and optimize the protection circuits based on MOV (varistors), transils, transzorbs, etc.
		It is possible, in addition, to measure and display the gate characteristics of a semiconductor by means of the IGT/VGT test.

	Forums de Abcelectronique - diodes transils vs diodes de redressement
		Pour l'instant je pense à la diode transil qui sert surtout à écreter les surtensions, mais je ne sais pas si mon raisonnement est bon.
		Si tu mets la diode en anti//, une diode de redressement suffit; si tu la montes aux bornes du transistor de commande, il faut une transil (ou zener); tu peux aussi monter une transil symétrique directement sur la bobine, et dans ce cas, ça marche aussi en AC.
		L'avantage que tu retireras d'une transil par rapport à une simple diode sera un temps de relachement beaucoup plus court: la diode prolonge l'extinction du courant et donc le délai de réponse.

		Or if you have to do secure the 5VDC supply against spikes with a fast transil and use fets like the 2N7000 to isolate the 932 pins from the 5V environment.
		Till now we had no problem with I2C pins but all other pins once in a while caused a damaged controller without these conditions.
		If You use the break detect method be sure that no unexpected breaks can cause the controller to switch to program mode ats tsrat up.

		The cheapest $5-7 a piece will do, the purpose is to have the power supply unit checkable by a single glance without having to debug around.
		In case of using generator power, transils for protecting the sensitive equipment from voltage spikes from the generator coils can save you money.
		Good to use by default when you don't trust the power supply.

		TTThrough the open frame around the connector, the RF signal transmitted by the antenna could be re-routed inside the phone, affecting each base band then RF blocks.
		This dual Transil structure will reduce the voltage applied to the SIM interface to just a few volts during the ESD transient, then will also protect the SIM supply line.
		The device fully complies with the IEC61000-4-2 standard level 4 (8kV in contact discharge then 15kV in air discharge).

		Los van het feit dat vrijloopdioden gebruikt worden, kan je ook VDR's (spanningsafhankelijke weerstanden) toepassen.
		Zenerdioden, transils, gewone weerstanden behoren ook tot de mogelijkheden.
		Met behulp van deze middelen kan je dan bepalen tot welke piekspanning er mag opgelingerd worden, daarboven wordt er gedempt.
