Good-Ark Semiconductor W06G

Overview

W06G from Diodes Incorporated is a 1.5A glass passivated single-phase bridge rectifier with 600V peak repetitive reverse voltage (VRRM), 1.0V forward voltage at 1.5A, and 50A non-repetitive surge current capability; used in AC/DC power supplies for industrial control panels requiring reliable mains input rectification.

For engineers reviewing the W06G datasheet, W06G pinout, W06G application, or W06G equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (84°C/W) under PCB-mount conditions, junction temperature limits (–65°C to +150°C), and UL recognition (E94661) for safety-critical designs.

Technical Context

The W06G integrates four silicon diodes in a single molded plastic WOG package, configured as a full-wave bridge with AC input terminals (A1, A2) and DC output terminals (+, –). Its glass passivated die construction ensures stable reverse leakage (5.0 µA at 25°C) and robust surge tolerance (50A, 8.3ms half-sine).

Thermal performance is defined for mounting on 13×13 mm² copper land areas (0.03 mm thick); total capacitance is 12 pF per element at 1 MHz and 4 V reverse bias, supporting low-noise operation in EMI-sensitive power stages.

FAQ

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

Per Fig. 1 in DS21202 Rev. 12, the W06G delivers full 1.5 A only up to 25°C ambient. At 75°C ambient, derated current is approximately 1.0 A; at 100°C, it drops to ~0.75 A. Thermal design must account for RθJC = 84°C/W and PCB copper area.

Is the W06G suitable for capacitive-input filter applications?

No-datasheet Note 1 explicitly requires 20% current derating for capacitive loads due to higher peak currents. For such topologies, use IO ≤ 1.2 A and verify ripple current ratings of downstream bulk capacitors.

Does the W06G meet lead-free soldering standards for reflow assembly?

Yes-the device features a lead-free finish compliant with RoHS Directive 2002/95/EC (exemptions applied per Annex 5 & 7), and its silver-plated leads are qualified for soldering per MIL-STD-202, Method 208.

What is the isolation voltage rating between case and terminals?

The W06G provides 1500 V RMS case-to-terminal isolation, verified per safety testing protocols. This rating supports reinforced insulation in Class II power supplies and enables use in medical auxiliary circuits meeting IEC 60601-1 creepage requirements.
