Product details

Transient protection spec by spec

The 1.5SMCJ40CA-AU_R1_000A1 is a bidirectional Zener TVS diode in the DO-214AB (SMC) surface-mount package, AEC-Q101 qualified for automotive deployments — the AU suffix marks the automotive-grade part within the 1.5SMCJ series.

What the automotive grade means for the BOM

AEC-Q101 qualification is a defined stress-test sequence — it is not the same as a commercial-grade part with a wide temp range on the datasheet. It is what the automotive customer requires for safety and reliability acceptance in the ECU or power-train module. The single bidirectional channel handles AC signal lines or any node that swings both polarities — for a single-ended 12 V or 24 V rail the unidirectional variant would give a lower clamping voltage at the same standoff, so confirm the line polarity before specifying the bidirectional type.

Frequently asked questions

Is the 1.5SMCJ40CA-AU_R1_000A1 a unidirectional or bidirectional TVS?

Bidirectional — the CA suffix in the SMCJ naming convention denotes the bidirectional polarity variant. For a unidirectional part on the same standoff and power class, the suffix would be CA removed or replaced with the unidirectional code.
