Product details

What the clamping spec means on the bench

The 1.5SMCJ78A_R1_00001: The 150 °C ceiling means this part can sit near a heat source or in an enclosed panel without derating below its listed peak pulse rating, which matters for outdoor enclosures and motor-drive compartments that run hot.

SMC package and what it means for board assembly

The tape-and-reel packaging suits high-volume pick-and-place, while cut-tape is available for low-quantity bring-up boards without committing to a full reel.

Listed as active by Panjit International Inc. — no EOL notice or official successor appears in the cross-reference record, so this is the current line item. No cross-reference or pin-compatible alternative is listed under the same series for this standoff voltage, so confirm the BOM position before committing to a second source.

Frequently asked questions

What type of protection does 1.5SMCJ78A_R1_00001 provide?

It is a unidirectional TVS Zener diode: the 78 V standoff keeps the line normal until a transient exceeds the breakdown threshold at 86.7 V minimum, then the device clamps the voltage to 126 V maximum and dissipates the surge energy at 1500 W peak pulse. It does not provide power-line protection (the line-protection flag is set to No), so it guards individual signal or rail nodes rather than an entire AC mains input.

What series and package is 1.5SMCJ78A_R1_00001?

It belongs to the 1.5SMCJ series and ships in the SMC (DO-214AB) surface-mount package. The supplier device package field lists SMC (DO-214AB) — the two naming conventions refer to the same JEDEC outline.
