1 Transil, transient voltage surge suppressor (TVS) Datasheet production data Features Peak pulse power: 600 W (10/0 µs ) Stand-off voltage range 6.8 to 440 V Unidirectional and bidirectional types Low clamping factor Fast response time UL recognized Complies with the following standards IEC level 4 15 kv (air discharge) 8 kv (contact discharge) MIL STD 883G, method Class 3 HBM (human body model) DO-15 (DO-204AC) 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 IC s.
