Product details

Overview

W005G-E4/51 from Vishay General Semiconductor is a glass passivated single-phase bridge rectifier in WOG package, rated for 50 V repetitive peak reverse voltage (V_RRM), 1.5 A average forward current (I_F(AV)), and 50 A non-repetitive surge current (I_FSM). It delivers 1.0 V forward voltage at 1.0 A per diode and supports operation from −55 °C to +150 °C - used in AC/DC power supplies for consumer adapters and lighting ballasts.

For engineers reviewing the W005G-E4/51 datasheet, W005G-E4/51 pinout, W005G-E4/51 application, or W005G-E4/51 equivalent, key selection criteria include V_RRM = 50 V, I_F(AV) = 1.5 A, thermal resistance R_θJA = 36 °C/W, low leakage (I_R = 5 μA @ 25 °C), and UL E54214 recognition for safety-critical board-level integration.

Technical Context

This device implements a quad-diode full-wave bridge configuration in a single molded WOG package, enabling compact AC-to-DC conversion without external interconnects. Its glass passivation ensures stable reverse characteristics and high reliability under thermal cycling and humid conditions.

Designed for PCB mounting with 0.375" (9.5 mm) lead length, it meets JESD 22-B106 solderability (275 °C, 10 s) and J-STD-002 plating standards. The silver-plated leads and UL 94 V-0 molding compound support automated assembly and flame-retardant compliance in consumer-grade power systems.

FAQ

What is the maximum operating temperature for W005G-E4/51?

The W005G-E4/51 has a specified operating junction temperature range of −55 °C to +150 °C. This allows reliable use in enclosed or thermally demanding environments such as LED drivers and appliance control boards. Derating is required above 25 °C ambient per the published derating curve, and thermal design must account for R_θJA = 36 °C/W on a 5.5 mm × 5.5 mm copper pad. The W005G-E4/51 maintains stable electrical performance across this full range when mounted per datasheet guidelines.

Does W005G-E4/51 meet RoHS and lead-free requirements?

Yes, W005G-E4/51 is RoHS-compliant and classified as commercial grade per its base P/N-E4 suffix. The device uses lead-free silver-plated leads and conforms to J-STD-002 solderability standards. Its molding compound meets UL 94 V-0 flammability rating, and material categorization aligns with Vishay's compliance documentation (www.vishay.com/doc?99912). The W005G-E4/51 is suitable for environmentally regulated markets without requiring exemptions.

What is the reverse leakage current specification for W005G-E4/51?

The W005G-E4/51 specifies a maximum DC reverse current (I_R) of 5.0 μA per diode at 25 °C and rated V_DC = 50 V. At 125 °C, leakage rises to 500 μA - a typical behavior for silicon rectifiers. This low room-temperature leakage supports energy-efficient standby modes in adapters and lighting. The W005G-E4/51 achieves this via glass passivation, which stabilizes surface conduction paths and reduces humidity-induced drift.

Can W005G-E4/51 be used in place of a discrete diode bridge?

Yes, W005G-E4/51 integrates four diodes in a single WOG package with fixed quad configuration (+, −, ~, ~), eliminating wiring errors and reducing PCB area versus discrete solutions. Its 1.5 A I_F(AV) and 50 A I_FSM match typical discrete bridge requirements for sub-15 W supplies. The W005G-E4/51 also provides consistent thermal coupling and matched V_F characteristics across all diodes - improving waveform symmetry and reducing EMI compared to hand-assembled discrete bridges.

What is the meaning of the "/51" suffix in W005G-E4/51?

The "/51" suffix in W005G-E4/51 denotes the preferred packaging code per Vishay's ordering information: it indicates the device is supplied in plastic bags containing 100 units each. This packaging format supports manual and semi-automated assembly lines. The "E4" prefix confirms RoHS-compliant, commercial-grade construction. The W005G-E4/51 part number uniquely identifies both compliance status and unit quantity per packaging option - critical for inventory and procurement accuracy.
