It is a single-channel bidirectional device, so it protects against both positive and negative transients without needing two diodes back-to-back. ## Junction temperature range and mounting It is supplied on Tape & Reel, making it compatible with automated pick-and-place assembly. The mounting type is surface mount, so no through-hole rework is needed. The part is sourced to order through our distribution network — no stock-holding claim, no immediacy promise.","metaTitle":"SMAJ18CE3/TR13 – Microchip 500W Zener TVS, 18V Standoff","metaDescription":"Microchip Technology SMAJ18CE3/TR13 Zener TVS diode: 500W peak pulse power, 18V reverse standoff, DO-214AC (SMA) surface mount.
