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.","metaTitle":"Vishay 1N4944GP-E3/54 Fast Recovery Diode, 400V 1A DO-204AL","metaDescription":"Vishay 1N4944GP-E3/54 SUPERECTIFIER® fast recovery diode, 400V 1A, 150ns trr, DO-204AL axial.
