Zener TVS diode, 20V standoff / 22.2V breakdown / 32.4V clamping, 1.5kW peak pulse, 46.3A peak pulse current, SMC (DO-214AB) surface-mount, -55°C to 150°C, unidirectional single-channel.","salesMarkdown":"## 20V standoff, 1.5 kW peak-pulse TVS in SMC The 1.5SMCJ20AS_R1_00001 is a unidirectional Zener-based TVS (Transient Voltage Suppressor) in the DO-214AB (SMC) package — one clamping channel that sinks transient energy away from the protected rail rather than crowbarring it to ground. The 32.4V clamping ceiling is the number that matters for downstream ICs — whatever is on that rail sees no more than that voltage during the event, assuming the peak pulse current stays within the 46.3A rating. ## Surface-mount SMC package and reel packaging SMC (DO-214AB) is a standard pick-and-place surface-mount package — the cathodes band on the tape identifies polarity unambiguously for automated assembly. For board layout, the SMC thermal pad under the body conducts heat to the copper plane — TVS dissipation is event-driven and short-duration, so continuous thermal management is not the constraint; the mount quality matters for mechanical robustness on the line rather than steady-state heat spreading.","metaTitle":"Panjit 1.5SMCJ20AS_R1_00001 TVS Diode, 20V Standoff, 1.5kW","metaDescription":"Panjit 1.5SMCJ20AS_R1_00001 unidirectional Zener TVS, 20V standoff, 22.2V breakdown, 32.4V clamping, 1.5kW peak pulse.
