Product details

54V rail clamp – 1500W in a DO-214AB footprint

Its 1500W peak pulse power rating (10/1000 µs) means it can absorb substantial surge energy without failing — useful for industrial power supplies, telecom rectifiers, and automotive auxiliary rails where the 54V standoff matches a nominal 48V bus or a 54V battery line.

Clamp voltage and junction temperature range

The wider the margin between the rail's normal operating voltage and the clamp, the safer the downstream components.

Active production – sourcing to order

Microchip lists the SMCJ54E3/TR13 as Active.

Frequently asked questions

What is the closest pin-compatible alternative to SMCJ54E3/TR13 in this Circuit Protection family?

Within the same SMCJ54 base number family, the SMCJ54A (unidirectional, 5% tolerance) and SMCJ54AE3 (enhanced-screening version) share the same DO-214AB footprint and 54V standoff. The SMCJ54E3/TR13 is the standard 5% tolerance variant with the /TR13 tape-and-reel suffix. Confirm the breakdown voltage tolerance your design requires before substituting.
