Product details

Obsolete — sourcing path for this TVS diode

The 1N6273ARL4 is listed as Obsolete by onsemi. Sourcing is per RFQ against the BOM quantity — availability and pricing confirmed at quote time.

1500W peak pulse power in a DO-201AD axial package

This is a single unidirectional Zener TVS diode rated for 1500W peak pulse power at 10/1000 µs waveform. The 10.2V reverse standoff voltage and 11.4V minimum breakdown voltage set the clamping threshold at 16.7V max. The DO-201AD axial package is through-hole mounted — the lead bend and body length are standard for this power level, so the PCB footprint matches any 1N6273-series socket.

Temp range and application fit

Junction temperature range is -65°C to 175°C, which covers military and industrial environments. No power line protection — this is a signal-rail or low-voltage DC bus clamp, not a mains-side suppressor. The Mosorb™ series is a standard onsemi TVS family; the 1N6273ARL4 is the tape-and-reel variant of the base 1N6273A.

Frequently asked questions

What is the replacement for 1N6273ARL4?

onsemi has not published an official replacement for the 1N6273ARL4. The base number 1N6273A (without the RL4 tape-and-reel suffix) is the same die in the same DO-201AD package — functionally identical, just different packaging format. For a direct parametric match, any 1500W, 10.2V standoff, 11.4V breakdown, 16.7V clamping TVS in DO-201AD will fit the same PCB footprint.

How does 1N6273ARL4 compare to the 1N6273A?

The 1N6273ARL4 is the tape-and-reel packaged variant of the base 1N6273A. All electrical ratings — 1500W peak pulse power, 10.2V standoff, 11.4V breakdown, 16.7V clamping — are identical. The only difference is the packaging format: RL4 indicates tape-and-reel for automated assembly; the base 1N6273A is typically supplied in bulk or ammo pack.
