What this protection diode does
The 1N6375 is a unidirectional Zener TVS diode from onsemi's Mosorb™ series, designed to clamp voltage transients on a 10V rail. It delivers 1500W peak pulse power (1.5kW) in an axial-lead package.
Voltage ratings and clamping behavior
With a reverse standoff voltage of 10V, the diode begins conducting at the minimum breakdown voltage of 11.7V and clamps the transient to a maximum of 16.7V at the peak pulse current. The 1500W rating assumes an 8/20 µs waveform per the Mosorb™ datasheet; real-world pulse width and duty cycle will shift the power capability.
onsemi lists the 1N6375 as Obsolete. For BOM positions that require this exact order code, the only channel is independent distribution — we source from verified inventory on the open market. Confirm the quantity and date-code requirements at quote time.
Mounting and thermal notes
The axial through-hole package has a junction temperature range of -65°C to 175°C. The copper lead diameter and board trace width set the thermal path — for repetitive pulsing, keep the lead length short and the solder fillet full to avoid hot-spotting at the glass passivation junction.
