Diode Reference Guide

This quick reference covers common rectifier, general-purpose, and switching diodes, along with their key voltage and current ratings.

Rectifier Diodes

SS510: 5A forward current, 100V reverse voltage

SS310: 3A forward current, 100V reverse voltage

SS210: 2A forward current, 100V reverse voltage

SS110: 1A forward current, 100V reverse voltage

General-Purpose & Switching Diodes

1N4448: 100V reverse voltage, 300mA forward current

1N4148: 100V reverse voltage, 300mA forward current

BAV21W: 250V reverse voltage, 250mA forward current

BAV20W: 200V reverse voltage, 200mA forward current

The SS-series devices are Schottky rectifier diodes commonly specified for higher-current rectification, while the 1N4448, 1N4148, BAV21W, and BAV20W are used in general-purpose or switching applications.

Technical note: Ratings can vary by manufacturer and exact device version. For example, manufacturer datasheets list different guaranteed current ratings for some 1N4448 and 1N4148 variants, so the manufacturer's datasheet should be checked before using a rating in a design.
