The 1.5KE56A-E3/54 is a unidirectional transient voltage suppressor (TVS) diode from Vishay Dale, part of the 1.5KE series. It features a glass passivated chip junction for reliable performance and is designed to protect sensitive electronics from voltage transients induced by inductive load switching and lightning.
Electrical specifications include a maximum clamping voltage of 77V at a peak pulse current of 19.5A (10/1000 µs waveform) and a peak pulse power dissipation of 1500W. The device has a typical forward voltage of 3.5V and can handle a peak forward surge current of 200A (8.3 ms single half sine-wave). Maximum power dissipation is 6.5W at a lead temperature of 75°C.
The diode is housed in a through-hole DO-201AA, DO-27, or Axial package with matte tin plated leads. It operates over a junction temperature range of -55°C to 175°C and is RoHS3 compliant (E3 suffix). Applications include general purpose voltage transient protection in consumer, computer, industrial, automotive, and telecommunication systems.
