It clamps transients at 22.5V maximum when the surge current hits, with a reverse standoff voltage of 13.6V — meaning the protected rail stays below that level during normal operation. The DO-201AD axial package is a through-hole legacy footprint, common in industrial power supplies, telecom line cards, and motor drive snubber circuits where board space isn't the constraint. ## Voltage ratings that define the protection window The breakdown voltage (minimum 15.2V) sits between the 13.6V standoff and the 22.5V clamp — that 2.6V margin is the avalanche region where the diode absorbs the surge. For a 12V nominal rail with 10% tolerance (13.2V max), the 13.6V standoff leaves only 0.4V headroom; a 12V rail at 5% tolerance (12.6V) is safer. The 1500W peak pulse rating at 1ms means the diode can handle a 66.7A surge at the clamp voltage — enough for most secondary-side transients in a 100W-class supply. ## Lifecycle reality — obsolete, not gone onsemi lists the 1N6276A as Obsolete. For sustainment programs — medical, defence, industrial control — this means the only sourcing path is the open market or a last-time buy from remaining distributor stock. ## Temperature range and mounting note Operating junction temperature spans -65°C to 175°C, which covers military and downhole environments. The through-hole axial body (DO-201AD) requires a 1.0mm to 1.3mm diameter hole on the PCB — the lead diameter is typically 0.96mm. No moisture sensitivity level applies to hermetic glass-passivated Zener diodes; no bake-out is needed before soldering.","metaTitle":"1N6276A Zener TVS Diode – onsemi Mosorb™ 1500W DO-201AD","metaDescription":"onsemi 1N6276A Mosorb™ Zener TVS, 1500W peak pulse, 13.6V standoff, 22.5V clamp.
