Product details

Zener TVS for 22V rail clamping

With a minimum breakdown voltage of 25.9V and a maximum clamping voltage of 37.5V at rated peak pulse current, this part provides a 3.9V margin above the 22V standoff before avalanche. That window suits protection of 24V bus lines where the steady-state rail sits at 22V or below.

Obsolete — sourcing through distribution

onsemi lists the 1N6379RL4 as Obsolete. For BOM lines requiring this exact order code, we source through our authorized and independent supply channels — quoted per RFQ against your target quantity.

The DO-201AD axial body is a standard through-hole footprint, easily hand-soldered or wave-soldered on single-sided boards.

Frequently asked questions

How can I order 1N6379RL4 or check availability?

The 1N6379RL4 is obsolete per onsemi. Submit an RFQ with your target quantity and we will confirm pricing and lead time against available stock. No stock-holding claim is made here.

What is the replacement for 1N6379RL4?

onsemi has not published an official successor for the 1N6379RL4. For a 22V rail requiring 1500W peak pulse in a DO-201AD axial package, consider the 1N6379 (base part without Tape & Reel suffix) if still available, or cross-reference to a current Littelfuse or Vishay Zener TVS with matching standoff and clamping voltages. We can assist with cross-referencing on request.

What is the difference between 1N6379 and 1N6379RL4?

The 1N6379RL4 is the Tape & Reel packaging variant of the base part 1N6379. Electrically identical — same 22V standoff, 25.9V breakdown, 37.5V clamp, 1500W rating. The RL4 suffix indicates reel packaging for automated assembly; the base 1N6379 may come in bulk or other packaging.
