2W06G-E4/51 Equivalent & Substitute Parts

Part Overview

The 2W06G-E4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. This through-hole component operates at 600 V peak reverse voltage with a 2 A average rectified current rating. The device is designed for AC-to-DC conversion applications requiring standard rectification technology. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for this diode category.

Substitute Part Grouping Explanation

Substitution eligibility for the 2W06G-E4/51 is determined by the following criteria:

Voltage rating must equal or exceed 600 V peak reverse voltage. Current rating must meet or exceed 2 A average rectified current. Forward voltage characteristics must be compatible with circuit design parameters. Reverse leakage current must not exceed specified limits at rated voltage. Operating temperature range must encompass -55°C to 150°C. Mounting configuration must be through-hole. Diode type must be single-phase bridge rectifier. Technology classification must be standard rectification.

The GBU2506-G meets these substitution criteria with equivalent voltage and temperature ratings, higher current capacity (4.2 A), compatible forward voltage performance, and matching through-hole mounting configuration.

Engineering Selection Recommendations

Both the 2W06G-E4/51 and GBU2506-G maintain Active product status and ROHS3 compliance. The GBU2506-G provides higher average rectified current capacity (4.2 A versus 2 A), making it suitable for applications requiring additional current headroom while maintaining identical voltage ratings and operating temperature specifications. Both components are classified as standard technology single-phase bridge rectifiers with through-hole mounting. Selection between these parts depends on circuit current requirements and PCB layout constraints related to package geometry (WOG versus GBU package configurations).

Frequently Asked Questions (FAQ)

Q: Can the GBU2506-G replace the 2W06G-E4/51 in existing designs?

A: Yes, provided the PCB layout accommodates the GBU package footprint. The GBU2506-G meets all electrical parameter requirements with equivalent voltage and temperature ratings. The higher current rating (4.2 A) is compatible with applications designed for 2 A operation.

Q: What is the primary difference between these two parts?

A: The GBU2506-G provides higher average rectified current capacity (4.2 A) compared to the 2W06G-E4/51 (2 A). Both maintain identical 600 V peak reverse voltage ratings and -55°C to 150°C operating temperature ranges. Package configurations differ (WOG versus GBU).

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance differences exist between the two components.

Q: What mounting considerations apply to substitution?

A: Both parts use through-hole mounting. Physical package dimensions differ between WOG and GBU configurations, requiring verification of PCB hole spacing and layout compatibility before substitution.

Q: How do forward voltage characteristics compare?

A: The 2W06G-E4/51 specifies 1.1 V maximum forward voltage at 2 A. The GBU2506-G specifies 1 V maximum at 12.5 A. Both are compatible for standard rectification applications within their respective current ratings.
