Product details

Zener TVS for 8V rail protection

The 1N6374 is a 1500W (1.5kW) peak pulse power Zener TVS diode from onsemi's Mosorb™ series, designed to clamp transients on an 8V nominal rail. Its 9.4V minimum breakdown voltage and 15V maximum clamping at Ipp ensure the protected circuitry sees no more than 15V during a surge event.

Obsolete — plan for replacement

onsemi lists the 1N6374 as Obsolete. Sourcing is through independent distribution; request a quote for current availability and pricing.

DO-201AD axial package — through-hole mounting

Housed in an axial-lead package, the 1N6374 is a through-hole device intended for wave-soldered or hand-soldered PCB assembly.
