Product details

Automotive temperature band in the DO-214AB SMC

The 1.5SMCJ26A-AQ: Surface-mount DO-214AB SMC package — the standard EIA-481 tape orientation is the norm; confirm the tape-and-reel quantity per reel matches the panelization pitch before setting up the pick-place head; the strip packaging option listed here is the tray equivalent for low-volume hand assembly or BGA-rework boards.

One-way protection — not a power-line part

Unidirectional, single-channel — it clamps positive transients and offers no reverse-polarity conduction protection; if the protected rail sees negative-going spikes or reverse polarity conditions, a bidirectional TVS or a reverse-polarity catch diode is required in series; this part does not provide power-line protection, so it is designed for signal-line or secondary rail clamping on a positively-biased node.

Frequently asked questions

Where can I source 1.5SMCJ26A-AQ and what is the typical lead time?

The part ships in the standard tape-and-reel or strip configuration depending on the distributor lot.

What package does the 1.5SMCJ26A-AQ use, and is it compatible with other TVS diodes in the same case size?

The SMC/DO-214AB surface-mount package is the industry-standard footprint; pin-compatible with other unidirectional TVS diodes in the same case size, but confirm the standoff voltage, clamping voltage, and peak pulse rating match the design before substituting — a different breakdown voltage changes the protection ceiling on the protected rail.
