2W08G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2W08G is a single-phase bridge rectifier manufactured by onsemi, rated for 800 V peak reverse voltage with 2 A average rectified current. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. Bridge rectifiers in this voltage and current class are fundamental components in AC-to-DC conversion circuits, power supply designs, and industrial rectification applications. The obsolete status necessitates sourcing from available substitute parts that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2W08G is determined by strict equivalence across all critical electrical parameters: peak reverse voltage (800 V), average rectified current (2 A), forward voltage drop (1.1 V @ 2 A), reverse leakage current (5 µA @ 800 V), and operating temperature range (-55°C ~ 150°C). Mechanical compatibility is ensured through identical mounting type (through hole) and package configuration (4-circular). The substitute part 2W08G-E4/51 maintains all these specifications while offering active product status and current availability, making it a direct functional equivalent for the obsolete 2W08G.
