With 83.3 V minimum breakdown, the 75 V standoff typ means the diode stays off during normal rail operation up to 75 V and switches into avalanche conduction only when a surge exceeds the breakdown threshold — the 8.3 V margin above standoff is the headroom the design needs to survive distributed-line transients without false triggering. ## Unidirectional, not power-line protected — confirming fit Single unidirectional channel — current flows in one polarity only, which is the correct polarity for a positive-supply rail clamp. For a bipolar or AC rail the bidirectional variant of the same series is the right choice. Power line protection is flagged No — this part is a unidirectional TVS, not a dedicated mains-protection device; it protects downstream load circuitry from surge events on signal or low-power supply lines, not the AC mains feed itself. ## DO-214AB SMC package — board integration note SMC (DO-214AB) is the mid-size surface-mount package in the SMB/DO-214AA/SMA family — the cathode bar marks polarity on the sleeve. Standard IR reflow profile applies; the wide thermal pad under the body handles the 1.5 kW peak pulse without special board reinforcement, but the layout should respect the recommended land pattern for thermal relief at the pad.","metaTitle":"1.5SMCJ75A_R1_00001 Panjit TVS Diode, 75V Standoff, DO-214AB","metaDescription":"1.5SMCJ75A_R1_00001 — Panjit unidirectional TVS diode, 75V standoff, 1500W peak pulse, 121V clamping, DO-214AB SMC.
