1N4937G-T Description

Short technical summary and product information.

The 1N4937G-T is a 600V, 1A fast recovery rectifier diode manufactured by Diodes Incorporated. It is part of the 1N4933G-1N4937G series and features a glass passivated die construction for reliable performance. The device offers a fast reverse recovery time of 200ns, making it suitable for high-efficiency switching applications. With a forward voltage drop of 1.2V at 1A and a non-repetitive peak surge current rating of 30A, it provides robust current handling.

 

This diode is packaged in a DO-41 (DO-204AL) axial leaded through-hole package, with bright tin-plated leads and a cathode band polarity marking. The case material is molded plastic with UL 94V-0 flammability classification. The operating junction temperature range is -65°C to +150°C, and the device is MSL Level 1 per J-STD-020D.

 

Typical applications include power supplies, inverters, and freewheeling diodes in switching circuits. The 1N4937G-T is RoHS compliant and lead-free finished.
