DBL205G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBL205G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for general-purpose rectification applications. This component operates at 600 V peak reverse voltage with a 2 A average rectified current rating and is housed in a 4-DIP through-hole package. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or application-specific qualification requirements.

Substitute Part Grouping Explanation

Substitute parts for the DBL205G are identified based on matching electrical and mechanical parameters that define functional equivalence in bridge rectifier applications. The critical parameters for substitution are:

Voltage - Peak Reverse (Max): 600 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 1.15 V @ 2 A
Current - Reverse Leakage @ Vr: 2 µA @ 600 V
Operating Temperature Range: -55°C ~ 150°C (TJ)
Package / Case: 4-DIP (0.300", 7.62mm)
Mounting Type: Through Hole

The DBL205GH qualifies as a parametric equivalent substitute because it maintains identical electrical specifications and mechanical packaging. The DBL205GH incorporates automotive-grade qualification (AEC-Q101) and is designated for automotive applications, representing an enhanced variant of the standard DBL205G within the same electrical performance envelope.
