1R5GU41 datasheet

Description

1R5GU41 diode is Silicon Diffused Type Duper Fast Recovery Rectifier. Ultra-Fast Recovery: With a 100 ns reverse-recovery time, it’s well-suited for high-frequency applications where efficiency and low switching losses are critical.

 

Features

1. Repetitive Peak Reverse Voltage  : VRRM = 400V

2. Average Forward Current  : IF (AV) = 1.5A (Ta = 25°C)

3. Very Fast Reverse−Recovery Time  : trr = 100ns

 

Absolute maximum ratings

1. Repetitive Peak Reverse Voltage : VRRM = 400 V

2. Average Forward Current : IF (AV) = 1.5 A

3. Peak One Cycle Surge Forward Current  (Non−Repetitive) : IFSM = 60 (50Hz), 66 (60Hz) A

4. Junction Temperature : Tj = – 40 ~ 150 °C

5. Storage Temperature Range : Tstg = – 40 ~ 150 °C

 

Applications

1. SMPS / DC–DC Converters: Fast recovery ensures reduced switching losses and minimal EMI.

2. Flyback / Boost Converters: Acts as a fast freewheeling or output rectifier.

3. Snubber and Hard-Switching Circuits: Where brief reverse currents and quick transitions demand sharp recovery.
