Product details

Fast recovery rectifier for 400 V rails — 150 ns trr

The 1N4944GP-E3/54: The 1N4944GP-/54: The Vishay 1N4944GP-/54 is a SUPERECTIFIER® standard fast recovery diode rated 400 V reverse voltage and 1 A average rectified current. Its 150 ns reverse recovery time places it squarely in the fast-recovery class, bridging the gap between a standard 1N400x (several µs) and an ultrafast (< 50 ns) Schottky or epitaxial diode. The 1.3 V forward voltage drop at 1 A is typical for a glass-passivated junction in this voltage class. The 1 µA reverse leakage at 400 V confirms the junction integrity for low-standby-power rectifier stages.

175°C junction — industrial and underhood thermal margin

Rated for an operating junction temperature range of -65°C to 175°C.

Active production, ROHS3 compliant — no LTB risk

Listed as Active on the manufacturer's lifecycle status, with ROHS3 compliance confirmed.

DO-204AL (DO-41) axial package — through-hole fit

Supplied in the DO-204AL axial-lead package. The through-hole mounting suits point-to-point wiring, terminal blocks, and PCB layouts.

Frequently asked questions

What is the reverse recovery time of 1N4944GP-/54?

The reverse recovery time (trr) is 150 ns, measured under standard test conditions. This qualifies it as a fast recovery diode suitable for 50–60 Hz line rectification with moderate switching stress.

Is 1N4944GP-/54 RoHS compliant?

Yes, it is listed as ROHS3 compliant, meeting the current EU RoHS exemption framework for lead-free soldering processes.
