Product details

AEC-Q101 TransZorb TVS for 12V/24V Automotive Rails

The 1.5KE56CAHE3_A/D: The 77V maximum clamping voltage at 19.5A peak pulse current ensures downstream ICs stay within their absolute maximum ratings.

Through-Hole Package and Thermal Profile

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE56CAHE3_A/D mounts through-hole — the leadframe conducts surge energy into the PCB copper pour. The junction temperature range spans -55°C to 175°C, covering the full automotive under-hood ambient plus self-heating margin during a transient. The bidirectional configuration (single channel) protects signal or power lines that swing both polarities, eliminating the need for two series diodes.

Active Production and Sourcing Posture

The base product number is 1.5KE56 — the full suffix (CAHE3_A/D) encodes the bidirectional polarity, AEC-Q101 qualification, and packaging (Tape & Box).

Frequently asked questions

What automotive qualification does 1.5KE56CAHE3_A/D carry?

It is AEC-Q101 qualified, part of Vishay's Automotive TransZorb series. The junction temperature range is -55°C to 175°C, suitable for under-hood and chassis-mounted electronics.
