It clamps transients from an 8 V reverse standoff rail, with a breakdown voltage minimum of 9.4 V and a clamping ceiling of 15 V at peak current. The through-hole axial body (DO-201AD) suits point-to-point wiring or PCB mounting where a soldered lead absorbs mechanical strain better than a surface-mount package. The -65°C to 175°C junction range covers cold-start and under-hood thermal cycles. ## Obsolete – source through independent distribution onsemi lists the 1N6374G as Obsolete. No official successor is published. For BOM lines that still call out this exact order code, independent distribution is the sourcing channel – we can quote against your quantity from available inventory or locate last-time-buy stock. The DO-201AD package and axial format are common across many Zener families, so a cross-reference search is worth the time if you are consolidating SKUs. ## Voltage ratings and clamping margin The 8 V reverse standoff is the maximum DC or peak AC voltage the diode will not conduct in normal operation. Above that, breakdown starts at 9.4 V minimum, and the clamping voltage is held to 15 V maximum at the rated peak pulse current. That 7 V window between standoff and clamp gives the downstream circuitry a defined transient suppression envelope.","metaTitle":"1N6374G onsemi Mosorb™ Zener – 1500W, DO-201AD, Obsolete","metaDescription":"onsemi 1N6374G Mosorb™ Zener, 1500W peak pulse, 8V standoff, DO-201AD axial.
