1.5KE Transil Datasheet production data Features Peak pulse power: 1500 W (10/1000 s) A Breakdown voltage range: From 6.8 V to 440 V Uni and bidirectional types K Low clamping factor Fast response time UL 497B file number: QVGQ2.E136224 DO-201 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.
