That 1500W rating is the energy the part can absorb in a single surge event — it sets the clamp voltage at 37.4V maximum when the peak current hits 40.1A. For a 20.6V reverse standoff rail, the clamp margin is about 16.8V above the working voltage, which gives downstream silicon enough headroom to survive an automotive load-dump or lightning-induced transient. ## Bidirectional channel — one part for bipolar or AC-coupled lines With a single bidirectional channel, the 1N6152AUS clamps both positive and negative transients symmetrically. That matters when the protected line swings through zero — think RS-485 pairs, audio lines, or sensor outputs where the signal is referenced to a virtual ground. A unipolar part would need two devices back-to-back; this one covers both polarities in one package. ## Active production — no last-time-buy clock ticking Microchip lists the 1N6152AUS as Active. ## SQ-MELF C — surface-mount footprint with a thermal twist The package is SQ-MELF, C-bend variant — a surface-mount body with solderable end caps. Unlike a standard SMB or SMC, the MELF body has no flat side for visual orientation, so the pick-and-place vision system must be programmed to recognise the cylindrical profile. The thermal pad is the end-cap metallisation; the board copper area under the body sets the junction-to-ambient thermal resistance. For a 1500W pulse, the PCB land pattern should follow Microchip's recommended footprint to keep the transient thermal impedance within the device's SOA.","metaTitle":"1N6152AUS TVS Diode - 1500W Bidirectional Zener, SQ-MELF","metaDescription":"1N6152AUS Zener TVS diode from Microchip Technology. 1500W peak pulse power, bidirectional, SQ-MELF package.
