Package and board integration
The 1.5KE150CAHE3_A/C: Housed in a DO-201AA (DO-27) axial-lead package, the part is through-hole mounted. The 1.5KE footprint is standard across the series — the same hole pattern accepts any 1.5KE voltage variant, so a single PCB layout covers multiple rail voltages.
Sourcing and compliance
The base product number is 1.5KE150; the full suffix includes the AEC-Q101 automotive designation and the bidirectional (CA) configuration. No official second-source or pin-compatible alternative is recorded from other manufacturers — the TransZorb series is Vishay-specific.
