SM4001 Description

Short technical summary and product information.

The SM4001 is a surface mount silicon rectifier diode manufactured by Vishay Dale. It is designed for applications requiring a voltage range of up to 1000 Volts and a current rating of 1.0 Ampere.

 

Key electrical specifications include a maximum recurrent peak reverse voltage of 1000V, a maximum RMS voltage of 700V, and a maximum DC blocking voltage of 1000V. The device has a maximum average forward rectified current of 1.0A at 75°C and a peak forward surge current of 20A. The maximum forward voltage is 1.1V at 1.0A DC, with a low DC reverse current of 50µA at 25°C and 5mA at 125°C.

 

This rectifier features a glass passivated junction and is ideal for surface-mounted applications. The case is molded plastic with UL 94V-0 rate flame retardant epoxy. It operates and stores within a temperature range of -65°C to +175°C. The terminals are solder plated and suitable for soldering per MIL-STD-202E, Method 208.

 

With its compact SM-1 (DO-213AB) package, the SM4001 is suitable for various electronic circuits where space is a constraint. Its low leakage current and robust construction make it a reliable choice for rectification tasks.
