Single bidirectional channel — one device handles both positive and negative transients, which simplifies layout on AC or bipolar DC lines. ## Active production, DO-214AC package The DO-214AC (SMA) package is a common footprint, reflow-solderable, and widely stocked in the distribution channel. That covers military-grade cold and hot environments — avionics, outdoor telecom, engine bay — without derating concerns. Surface-mount DO-214AC (SMA) — the two-pad footprint is easy to hand-solder or reflow. Polarity is marked on the body; for a bidirectional part the marking is symmetric, so orientation is not critical.","metaTitle":"SMAJ33CE3/TR13 – Microchip 500W Zener TVS, 33V, DO-214AC","metaDescription":"SMAJ33CE3/TR13 Zener TVS diode from Microchip Technology. 500W peak pulse power, 33V reverse standoff, DO-214AC.
