Product details

Automotive-grade protection with AEC-Q101

The 1.5KE100CAHE3_B/C: This part carries AEC-Q101 qualification, meaning it has passed the stress tests for automotive-grade discrete semiconductors — temperature cycling, high-temperature reverse bias, and ESD robustness — so it belongs in a BOM for an ECU, a battery-management system, or a body controller that sees under-hood temperatures.

Package and field-fit for the DO-201AA axial

Housed in a DO-201AA (DO-27) axial-lead package, it is a through-hole part — the leads are long enough to form into a PCB hole or a terminal block, and the body is large enough to dissipate the 1500 W pulse without external heatsinking.

Frequently asked questions

Where can I buy the 1.5KE100CAHE3_B/C and get a price?

Submit an RFQ with your target quantity and we will confirm availability and current pricing at quote time.

What is the closest pin-compatible alternative to the 1.5KE100CAHE3_B/C?

The part is a standard DO-201AA axial TVS, so any 1500 W bidirectional TVS with the same standoff voltage (85.5 V) and similar clamp voltage will share the same footprint — but the AEC-Q101 qualification and TransZorb series characteristics are specific to this order code.
