Product details

18V rail clamp with 1.5kW surge capacity

The SMCJ18AE3/TR13 is a unidirectional Zener TVS diode from Microchip Technology, designed to protect a single 18V rail from transients up to 1500W peak pulse power (10/1000µs waveform). Breakdown occurs at a minimum of 20V, and the clamping voltage is held to 29.2V at the rated peak pulse current of 51.4A — the downstream circuitry must survive that clamp voltage for the pulse duration.

Active production, sourced per RFQ

Temperature range and mounting note

Rated for junction temperatures from -65°C to 150°C, covering industrial and some military-ambient environments.

Frequently asked questions

Can the SMCJ18AE3/TR13 replace the SMCJ18A?

The SMCJ18AE3/TR13 shares the same base number (SMCJ18) and DO-214AB package as the standard SMCJ18A. The '' suffix indicates Microchip's lead-free / RoHS-compliant finish. Electrical ratings — 18V standoff, 20V breakdown, 29.2V clamp, 1500W peak pulse — are identical to the standard SMCJ18A. It is a direct drop-in replacement for the non- version.
