Summary
Transil?? transient voltage surge suppressor (TVS) 14-Dec-2012
Description
Transil diodes provide high overvoltage protection by clamping action. Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied ICs.
