Product details

The 1N6381G is a Zener transient voltage suppressor from onsemi's Mosorb™ series, designed for general-purpose circuit protection in through-hole assemblies. It delivers 1500W (1.5kW) peak pulse power at 10/1000 µs, clamping transients to 78.9V maximum at the rated peak pulse current. The reverse standoff voltage of 45V means this device protects a 45V nominal rail — common in 48V telecom or industrial bus applications — without conducting during normal operation.

Available inventory is limited to distributor stock and surplus lots. Each RFQ is sourced against the BOM quantity, with date-code and condition verified before commitment.

The 1N6381G is a through-hole device in an axial leaded package, intended for manual or wave-solder assembly on standard PCB layouts.
