Zener TVS for 5.8V rail clamping
The 1N6267ARL4 is a unidirectional Zener TVS diode from onsemi's Mosorb™ series, designed to clamp transients on a 5.8V nominal rail. Its 6.45V minimum breakdown voltage triggers clamping at 10.5V maximum under peak pulse current, absorbing 1500W of surge energy in a DO-201AD axial package.
Surge rating and thermal limits
Rated for 1500W peak pulse power at 1ms pulse width, the 1N6267ARL4 handles high-energy transients typical of inductive load switching or lightning surge on low-voltage DC buses. The junction operates from -65°C to 175°C, so the part can sit in hot environments like an engine bay or power supply output without derating the clamping voltage.
Obsolete – sourcing window is closing
onsemi has marked the 1N6267ARL4 as Obsolete. No official successor is listed on the record. For existing BOM lines, the last-time buy window is effectively past – remaining stock in franchised or independent channels is the only supply. Sourcing is per RFQ; availability and pricing are confirmed at quote time against the required quantity.
Package and mounting
Through-hole axial package with tape-and-reel or cut-tape options. The axial leads suit point-to-point wiring or PCB through-hole mounting.
