The 85 V reverse standoff (typ) sets the rail voltage the TVS guards without turning on — a 24 VDC rail sits comfortably below this, so the device remains off during normal operation and activates only on a surge event. ## Peak pulse power and temperature margin The junction temperature limit is 150°C, which gives headroom in enclosed panels where ambient can run to 85°C — the derating curve in the datasheet tells you how much of the 1500 W is usable at your actual ambient. Unidirectional polarity means this is a DC-rail clamp — it protects the positive rail relative to ground. AC line protection requires a bidirectional TVS or a back-to-back pair. ## Package and active sourcing The SMC (DO-214AB) package is the standard JEDEC footprint for 1.5–3 kW TVS diodes — the cathode bar on the top face is the thermal and electrical contact; the recommended land pattern uses a copper pad sized to the datasheet thermal recommendation.","metaTitle":"1.5SMCJ85AS_R1_00001 Zener TVS, 85V standoff, SMC","metaDescription":"Panjit 1.5SMCJ85AS_R1_00001 Zener TVS, 85V standoff, 137V clamping, 1.5kW peak pulse, SMC (DO-214AB).
