Diodes Incorporated 2W005G

Overview

2W005G from Diodes Incorporated is a 2.0A glass passivated bridge rectifier with 50V 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 2W005G datasheet, 2W005G pinout, 2W005G application, or 2W005G equivalent, key selection factors include its WOG package thermal resistance (40°C/W), 1500V case-to-terminal isolation, and derating behavior above 25°C ambient per Figure 1.

Technical Context

This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic WOG molded plastic case. It operates under resistive or inductive loads at 60Hz, with mandatory 20% current derating for capacitive loads.

Thermal performance is defined with 13×13mm PCB copper land areas (0.03mm thick); junction-to-case thermal resistance is 40°C/W. Reverse leakage is specified at 5.0μA @ 25°C and 500μA @ 125°C under rated DC blocking voltage.

Key Specifications

Pinout & Package

Package: WOG - Molded plastic case, UL 94V-0 rated, 1.3g weight, silver-plated leads solderable per MIL-STD-202 Method 208. Polarity marked on body: AC terminals (±) and DC output (+/−).

Key Features

Applications

Equivalent & Alternatives

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

Compared with GBU4A and DB105, the 2W005G offers superior board-level integration via WOG package, certified 1500V isolation, and UL recognition - making it preferred for safety-regulated industrial and lighting applications despite its "Not Recommended for New Design" status due to obsolescence planning.

Availability

2W005G is available at Aetrix Electronics and suitable for LED driver power supplies, industrial PLC input stages, AC-DC wall adapters, and appliance motor control boards requiring stable component supply and legacy design continuity.

Supply support for 2W005G 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 2W005G RoHS compliant?

Yes, the 2W005G is RoHS compliant with lead-free finish per EC Directive 2002/95/EC (RoHS), effective for date codes 0514 and later. Exemptions for glass and high-temperature solder apply per EU Directive Annex Notes 5 and 7.

What is the maximum operating temperature for the 2W005G?

The 2W005G has an operating and storage temperature range of −65°C to +150°C. Its thermal derating curve (Figure 1) shows usable average current drops to ~1.2A at 75°C ambient and ~0.6A at 125°C ambient with the specified PCB layout.

Can the 2W005G be used in capacitive-load applications?

Yes, but with mandatory 20% current derating from the rated 2.0A IO. Capacitive loads cause high inrush currents that stress the junction; the 60A IFSM rating helps absorb this, but sustained operation requires reduced average current to avoid thermal overload.

Why is the 2W005G marked "Not Recommended for New Design"?

This designation reflects Diodes Incorporated's product lifecycle management - the part remains fully manufactured and supported, but newer alternatives with improved efficiency, smaller footprints, or enhanced surge ratings are recommended for new projects to ensure long-term supply and performance optimization.
