W005G Bridge Rectifier Single Phase 50V 1.5A Equivalent & Substitute Parts

Part Overview

The W005G is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 50V peak reverse voltage and 1.5A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The W005G operates across a temperature range of -65°C to 150°C and is housed in a 4-Circular WOG through-hole package. ROHS3 compliance and REACH affected status are applicable to this part.

Substitute Part Grouping Explanation

Substitution eligibility for the W005G is determined by the following critical parameters: single-phase diode type, standard technology classification, 50V peak reverse voltage rating, through-hole mounting configuration, and ROHS3 compliance. The average rectified current rating and forward voltage characteristics are secondary selection criteria that define functional equivalence within application-specific constraints.

Two substitute parts are identified:

DF005M (Fairchild Semiconductor): Maintains identical voltage rating (50V), single-phase topology, standard technology, and through-hole mounting. Current rating is reduced to 1A average rectified current with slightly elevated forward voltage (1.1V @ 1A). Package configuration differs (4-EDIP vs. 4-Circular WOG). Product status is active.

W005G-E4/51 (Vishay General Semiconductor - Diodes Division): Maintains identical voltage rating (50V), current rating (1.5A), forward voltage (1V @ 1A), reverse leakage (5µA @ 50V), single-phase topology, standard technology, and package configuration (4-Circular WOG). Operating temperature range is -55°C to 150°C. Product status is active. RoHS3 compliant.

Engineering Selection Recommendations

W005G-E4/51 is the primary substitute for the obsolete W005G. This part maintains identical electrical specifications (50V, 1.5A, 1V forward voltage, 5µA reverse leakage), identical package configuration (4-Circular WOG), and active product status. ROHS3 compliance is confirmed. The operating temperature minimum is -55°C versus -65°C for the original part; applications requiring operation below -55°C require thermal analysis validation.

DF005M is a secondary substitute suitable for applications where current requirements do not exceed 1A average rectified current. This part maintains 50V voltage rating, standard technology, and through-hole mounting. The package configuration differs (4-EDIP vs. 4-Circular WOG), requiring PCB layout modification. Forward voltage is elevated to 1.1V @ 1A, and reverse leakage is doubled to 10µA @ 50V. Active product status and full temperature range (-65°C to 150°C) are available.

Frequently Asked Questions (FAQ)

Q: Can DF005M directly replace W005G in existing designs? A: DF005M is electrically compatible for applications rated at 1A or below. However, the package configuration differs (4-EDIP vs. 4-Circular WOG), requiring PCB footprint modification. Forward voltage and reverse leakage specifications differ; thermal and noise performance may vary.

Q: Is W005G-E4/51 a pin-for-pin replacement? A: Yes. W005G-E4/51 maintains identical package configuration (4-Circular WOG), electrical ratings (50V, 1.5A), and forward voltage characteristics (1V @ 1.5A). No PCB layout changes are required.

Q: What is the impact of the -55°C minimum operating temperature on W005G-E4/51? A: W005G-E4/51 operates from -55°C to 150°C, compared to W005G's -65°C to 150°C range. Applications requiring operation below -55°C must use DF005M or source alternative parts with extended low-temperature ratings.

Q: Are both substitute parts ROHS3 compliant? A: W005G-E4/51 is confirmed ROHS3 compliant. DF005M compliance status is not specified in available documentation.

Q: How do reverse leakage specifications affect circuit performance? A: W005G and W005G-E4/51 specify 5µA @ 50V reverse leakage. DF005M specifies 10µA @ 50V. Higher reverse leakage increases standby current and heat dissipation in high-impedance circuits; applications with stringent leakage requirements should prioritize W005G-E4/51.
