Good-Ark Semiconductor 2W08G

Overview

2W08G from Diodes Incorporated is a 2.0A glass passivated bridge rectifier with 800V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 2.0A, and 60A non-repetitive surge capability - used for AC-to-DC conversion in offline power supplies, LED drivers, and industrial control power stages.

For engineers reviewing the 2W08G datasheet, 2W08G pinout, 2W08G application, or 2W08G equivalent, key selection criteria include VRRM rating, thermal resistance (40°C/W), case isolation voltage (1500V), RoHS-compliant silver-plated leads, and WOG package compatibility with PCB mounting.

Technical Context

This single-phase, full-wave bridge rectifier integrates four silicon diodes in a molded plastic WOG package with glass-passivated junctions to ensure stable reverse leakage (<5.0μA @ 25°C) and high surge tolerance. It operates across –65°C to +150°C and supports resistive/inductive loads at 60Hz.

Thermal performance is defined with 13×13mm PCB copper land areas; derating begins above 25°C ambient, dropping to ~1.2A at 75°C. Capacitance is low (16pF typical per element), minimizing high-frequency noise coupling in switching applications.

Key Specifications

Pinout & Package

Package: WOG - Molded plastic case (UL 94V-0), 9.35mm × 4.30mm × 26.65mm (A/B/D max), 1.3g weight, silver-plated leads solderable per MIL-STD-202 Method 208.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar bridge rectifier applications.

Compared with GBU8K and KBP208, the 2W08G offers UL recognition and optimized thermal design for PCB-only cooling - making it preferable where safety certification, space constraints, and no-heatsink operation are mandatory.

Availability

2W08G is available at Aetrix Electronics and suitable for industrial PLC power inputs, LED driver power supplies, AC fan motor controls, and appliance auxiliary power conversion requiring stable component supply and long-lifecycle support.

Supply support for 2W08G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

Is the 2W08G RoHS compliant?

Yes - the 2W08G carries RoHS compliance per EU Directive 2002/95/EC for date codes 0514 and later, using lead-free silver-plated leads and exempted high-temperature solder materials as specified in Annex Notes 5 and 7.

What is the maximum operating temperature for continuous use?

The 2W08G supports continuous operation from –65°C to +150°C junction temperature. At 75°C ambient, its average output current must be derated to approximately 1.2A per the forward current derating curve in Figure 1 of DS21204.

Can the 2W08G replace the 2W06G in a design?

Yes - the 2W08G shares identical WOG packaging, thermal characteristics, and pinout with the 2W06G (600V VRRM), offering higher reverse voltage margin. No layout change is needed, and it improves surge resilience in 230VAC systems with line transients.

Why is the 2W08G marked "NOT RECOMMENDED FOR NEW DESIGN"?

This designation reflects Diodes Incorporated's internal product lifecycle guidance - indicating newer alternatives (e.g., higher-efficiency GBU or KBU series) are preferred for new projects. The 2W08G remains fully qualified, in production, and supported for existing designs and legacy BOMs.
