Its 8.5 V reverse standoff voltage protects 8 V–9 V DC rails, with a minimum breakdown of 8.89 V and a maximum clamping voltage of 13.6 V at 110.3 A peak pulse current. The 1500 W rating means this diode can absorb a 1 ms surge that would destroy a smaller device — the kind of transient from an inductive load dump or a lightning-coupled spike on a 12 V battery line. The 8.5 V standoff allows it to sit across a 5 V or 8 V rail without leaking appreciably, then clamp hard when the rail rises above 8.89 V. ## Breakdown and Clamping Margins With a breakdown voltage range starting at 8.89 V, this part triggers before the protected IC's absolute maximum rating — typically 10–12 V for 5 V logic or 8 V for 3.3 V I/O. The 13.6 V clamp ensures the voltage never exceeds the downstream device's avalanche limit, even at full surge current. The 110.3 A peak pulse current (at 10/1000 µs) is the current the diode can shunt during the surge. For a 1500 W rating, this current aligns with a clamping voltage of 13.6 V — the product of current and clamp voltage equals the power rating within measurement tolerance. ## Active Production, DO-214AB Package The - suffix indicates lead-free / RoHS-compliant termination finish, meeting current environmental directives without requiring a separate waiver. ## Temperature Grade and Environment Fit The wide Tj range also means the leakage current at high temperature stays within the datasheet limits — critical for standby power budgets in battery-backed systems.","metaTitle":"SMCJ8.5AE3/TR13 TVS Diode – 1500 W, 8.5 V Standoff, DO-214AB","metaDescription":"Microchip Technology SMCJ8.5AE3/TR13 Zener TVS, 1500 W peak pulse, 8.89 V breakdown min, 13.6 V clamping.
