Its reverse standoff voltage is 15V, meaning it stays off during normal operation. When the line sees a surge, breakdown occurs at a minimum of 17.6V, and the diode clamps the peak to 25V while absorbing up to 1500W of peak pulse power. That 1500W rating is the 10/1000 µs waveform — enough to handle inductive kickback, lightning-induced spikes, or load-dump events in industrial and automotive auxiliary circuits. onsemi lists the 1N6377RL4 as Obsolete. For BOM lines that still call out this exact order code, the only sourcing path is through independent distributors who hold existing stock or can locate inventory from surplus channels. ## Package and mounting — DO-201AD axial leaded The 1N6377RL4 comes in a DO-201AD axial package, a through-hole form factor with two wire leads. It mounts by inserting the leads into plated through-holes on the PCB and soldering.","metaTitle":"1N6377RL4 onsemi Mosorb™ Zener TVS – Obsolete, 1500W","metaDescription":"onsemi 1N6377RL4 Mosorb™ Zener TVS diode, 1500W peak pulse, 15V reverse standoff, 17.6V breakdown, 25V clamp.
