Product details
Overview
W01G from Diodes Incorporated is a 1.5A glass passivated single-phase bridge rectifier with 100V 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 modules, LED drivers, and appliance power stages.
For engineers reviewing the W01G datasheet, W01G pinout, W01G application, or W01G equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (84°C/W), junction-to-case isolation, UL recognition (E94661), and RoHS-compliant silver-plated leads solderable per MIL-STD-202.
Technical Context
The W01G integrates four silicon diodes in a single molded plastic WOG package to form a full-wave bridge configuration, enabling AC input conversion without external interconnects. Its glass passivated die construction ensures stable reverse leakage (<5 µA at 25°C) and robust surge tolerance under 8.3ms half-sine transients.
Designed for PCB mounting with 13×13 mm copper land areas, it delivers 1.5A average output current at 25°C ambient, derated linearly to zero at 125°C - validated per Fig. 1 derating curve. Total capacitance is 12 pF per element at 1 MHz and 4V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum peak reverse voltage before breakdown; defines safe AC input range for 70V RMS systems |
| IO | 1.5 A - continuous DC output current at 25°C ambient with specified PCB copper area |
| VFM | 1.0 V @ 1.5A - total forward drop across two series diodes in conduction path; impacts power loss and thermal design |
| IFSM | 50 A - surge rating for 8.3ms half-sine waveform; supports inrush current in transformer-coupled supplies |
| RθJC | 84 °C/W - thermal resistance from junction to case; determines temperature rise under load with proper heatsinking |
| CT | 12 pF per element - low junction capacitance minimizes high-frequency noise coupling in switching applications |
| Isolation Voltage | 1500 V - case-to-terminal withstand voltage; meets reinforced insulation requirements for Class II appliances |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1K (ON Semiconductor) | Same 1.5A IO and 100V VRRM; GBU package has larger footprint (18.8 × 13.2 mm vs. WOG's 9.3 × 4.3 mm) and higher RθJC (100°C/W) | Preferred where board space permits and higher surge margin (60A IFSM) is required | Select GBU1K only if PCB layout accommodates larger body and thermal management supports higher junction rise |
| MB1S (Vishay) | Lower 1.0A IO rating and 100V VRRM; SMB surface-mount package (4.6 × 3.6 mm); no UL recognition | Suitable for low-power, space-constrained designs where safety certification is not mandated | Choose MB1S only for cost-sensitive, non-safety-critical applications with <1A load current |
Compared with GBU1K and MB1S, the W01G uniquely balances compact WOG through-hole packaging, UL recognition, 1500V isolation, and 50A surge rating - making it optimal for certified industrial and appliance power supplies requiring reliability and regulatory compliance.

FAQ
What is the maximum allowable ambient temperature for continuous 1.5A operation?
The W01G delivers its full 1.5A average output current only at 25°C ambient temperature. As shown in Fig. 1 of the datasheet, current must be linearly derated to zero at 125°C ambient when mounted on a 13×13 mm PCB copper area. At 75°C ambient, the usable current drops to approximately 0.75A.
Does the W01G require a heatsink for 1.5A operation?
No external heatsink is required for 1.5A operation at 25°C ambient, provided the device is mounted on a PCB with minimum 13×13 mm (0.03 mm thick) copper land areas per terminal. The 84°C/W junction-to-case thermal resistance assumes this layout; smaller copper areas will increase junction temperature and necessitate current derating.
Is the W01G suitable for capacitive-load applications like switch-mode power supplies?
Yes, but with mandatory 20% current derating per the datasheet note. For example, at 1.5A rated IO, maximum continuous current under capacitive loading is 1.2A. This accounts for higher peak currents drawn during capacitor charging cycles, which increase thermal stress beyond resistive/inductive load conditions.
What safety certifications does the W01G hold?
The W01G is UL Recognized under Component Index File E94661, compliant with UL 60747-4. It also meets RoHS Directive 2002/95/EC (with glass and high-temp solder exemptions), carries DC 514+ lead-free finish, and provides 1500V case-to-terminal isolation - satisfying reinforced insulation requirements for Class II equipment.
