Zener diode for transient suppression
The 1N6268ARL4G is a unidirectional Zener diode from onsemi's Mosorb™ series, designed for general-purpose transient voltage suppression. It delivers a peak pulse power rating of 1500W (1.5kW) to clamp overvoltage events, with a reverse standoff voltage of 6.4V and a breakdown voltage minimum of 7.13V. The clamping voltage at peak pulse current is 11.3V max, defining the protection ceiling for the downstream circuit.
Package and mounting for through-hole assembly
Housed in an axial-lead package, the 1N6268ARL4G is a through-hole component suited for wave-solder assembly on single-sided or double-sided boards. The axial leads simplify hand-replacement in rework or field-service scenarios, though the part's obsolescence means new designs should consider surface-mount alternatives for automated assembly lines.
Sourcing reality for an obsolete Mosorb™ diode
onsemi has marked the 1N6268ARL4G as Obsolete. For BOM lines that require this exact order code, procurement should treat it as a last-time-buy candidate. We can source and quote against an RFQ — confirm the required quantity and date-code window, and we will check multi-supplier availability. The wide operating junction temperature range of -65°C to 175°C still applies to any authentic stock found, making it viable for harsh-environment repairs if the date code is verified.
