It clamps a transient at 26.5 V maximum when the peak current hits 107 A under the 8/20 µs waveform. That 26.5 V clamp ceiling is what the downstream silicon sees — if your rail is a 15 V bus, the 1N6464 holds the surge well below a typical 30 V absolute-max of a downstream regulator. ## Breakdown and Clamp Window The reverse standoff voltage is 15 V — the rail voltage the part leaves alone during normal operation. Breakdown starts at 16.4 V minimum, so on a 15 V supply the diode begins conducting about 1.4 V above the rail, well before the clamp voltage of 26.5 V. That gap between standoff and breakdown gives margin for steady-state ripple without the diode chewing up leakage current. ## Thermal and Package Reality The junction temperature range spans -55°C to 175°C, which covers both cold-start in outdoor gear and self-heating during repetitive surge events. The part comes in an axial-lead through-hole package (B, Axial) — the leads carry the surge current into the PCB, so the trace width from the anode and cathode pads to the protected rail needs to handle the 107 A peak without fusing. ## Active Production — Sourcing Posture For current pricing and lead time, the part is quoted to order against the BOM quantity — no stock-holding claim is made here, but the supply chain is open.","metaTitle":"1N6464 Zener TVS Diode – 500W, 15V Standoff, Axial","metaDescription":"1N6464 Zener TVS diode from Microchip Technology – 500W peak pulse, 15V standoff, 26.5V clamp, 107A (8/20µs).
