Good-Ark Semiconductor W10G

Overview

W10G from Diodes Incorporated is a 1.5A glass passivated single-phase bridge rectifier with 1000V peak repetitive reverse voltage (VRRM), 1.0V forward voltage at 1.5A (VFM), and 50A non-repetitive surge current rating (IFSM), used for AC-to-DC conversion in offline power supplies, LED drivers, and industrial control power stages.

For engineers reviewing the W10G datasheet, W10G pinout, W10G application, or W10G equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (84°C/W junction-to-case), case isolation voltage (1500V), and UL recognition (E94661) for safety-critical designs.

Technical Context

The W10G integrates four silicon diodes in a single molded plastic WOG package with internal bridge topology, enabling full-wave rectification without external interconnects. It supports 60Hz single-phase resistive/inductive loads and requires 20% current derating under capacitive loading per datasheet Note 1.

Thermal performance is defined with 13×13mm PCB copper land areas (0.03mm thick); typical total capacitance is 12pF per element at 1MHz/4V reverse bias, and reverse leakage remains ≤5µA at 25°C and ≤500µA at 125°C under rated blocking voltage.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with GBU10K and KBP1010, the W10G offers optimal thermal performance (84°C/W) in the compact WOG form factor while maintaining full 1.5A continuous rating and 1000V robustness-making it preferred for space-constrained, thermally demanding AC-DC front-ends.

FAQ

What is the maximum ambient temperature for continuous 1.5A operation?

The W10G delivers full 1.5A average output current only at TA = 25°C, as specified in the derating curve (Fig. 1). At 75°C ambient, its usable current drops to ~0.9A; operation above 125°C ambient is prohibited. Thermal design must ensure junction temperature stays ≤150°C using the 84°C/W RθJC value and appropriate PCB copper area.

Does the W10G require external snubbers for inductive load switching?

No external snubber is required for standard 60Hz inductive loads per datasheet conditions. However, when switching highly inductive loads (e.g., solenoids or relays) on the DC output side, transient suppression (e.g., TVS or RC network) should be added downstream-not across the W10G terminals-to protect connected logic or regulators from flyback spikes.

Can the W10G be used in a center-tapped transformer configuration?

No-the W10G is a monolithic full-wave bridge with fixed internal connections and four dedicated terminals (~, ~, +, −). It cannot substitute for dual-diode configurations used with center-tapped secondaries. For such topologies, discrete diodes (e.g., 1N4007 × 4) or dual common-cathode packages are required instead.

Is the W10G suitable for high-frequency AC inputs (e.g., 20kHz from an inverter)?

No-it is characterized and rated exclusively for 50/60Hz operation. At 20kHz, junction capacitance (12pF) and reverse recovery behavior (not specified in datasheet) cause excessive switching losses and potential thermal runaway. For high-frequency rectification, fast-recovery or ultrafast diodes (e.g., FR107, UF4007) must be used instead.
