The 1N6280ARL4 is a unidirectional Zener TVS diode from the onsemi Mosorb™ series, rated for 1500W peak pulse power at 10/1000 µs waveform. The 20.5V reverse standoff voltage lets it sit on a 20V rail without leakage; clamping starts at 22.8V breakdown and holds the load to 33.2V maximum during a surge.
onsemi lists the 1N6280ARL4 as Obsolete.
Designers and maintenance techs need a direct drop-in or functionally equivalent part because 1N6280ARL4 is obsolete.
Engineers and buyers must know if the part is end-of-life to plan redesigns or source alternatives.
Transactional intent for sourcing buyers needing to fill a BOM line or replace a failed unit immediately.
Design engineers validating fit need precise parameters to ensure compatibility with the circuit.
Brokers and buyers evaluate multiple sources when the original onsemi part is unavailable.
Common confusion between suffix variants requires clarification to avoid compatibility issues.
