Product details
Overview
W02G from Diodes Incorporated is a 1.5A glass passivated single-phase bridge rectifier with 200V 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 requiring compact, RoHS-compliant rectification.
For engineers reviewing the W02G datasheet, W02G pinout, W02G application, or W02G equivalent, key selection criteria include VRRM derating for capacitive loads, thermal resistance (84°C/W) for PCB layout, junction temperature limits (–65°C to +150°C), and UL recognition (E94661) for safety-critical designs.
Technical Context
The W02G integrates four silicon diodes in a single molded plastic WOG package, configured as a full-wave bridge with isolated case-to-terminal insulation rated at 1500V. It operates under single-phase 60Hz resistive or inductive loads, with mandatory 20% current derating for capacitive loads per datasheet Note 1.
Thermal performance is defined for mounting on a 13×13mm PCB copper land (0.03mm thick), yielding RθJC = 84°C/W. Total capacitance is 12pF per element at 1MHz and 4V reverse bias, supporting high-frequency noise filtering in switching supply front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage before breakdown; sets minimum input AC voltage rating for safe operation. |
| IO (TA=25°C) | 1.5 A - Average rectified output current; requires thermal derating above 25°C ambient per Fig. 1 curve. |
| VFM @ 1.5A | 1.0 V - Forward voltage per diode pair; determines conduction loss (≈1.5W at full load). |
| IFSM | 50 A - Peak surge current tolerance for 8.3ms half-sine; supports inrush current handling in transformer-fed supplies. |
| RθJC | 84 °C/W - Junction-to-case thermal resistance; defines minimum heatsinking requirement when mounted on specified PCB land. |
| CT (per element) | 12 pF - Junction capacitance at 1MHz/4V; impacts EMI filtering and high-frequency reverse recovery behavior. |
| Tj/TSTG | –65°C to +150°C - Operating and storage range; enables deployment in extended-temperature industrial environments. |
Pinout & Package
Package: WOG - Molded plastic case, UL 94V-0 rated, 1.3g weight, with silver-plated leads solderable per MIL-STD-202 Method 208. Case-to-terminal isolation voltage: 1500V.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| ~ (AC2) | AC Input Terminal 2 | Second AC input node; completes full-wave bridge input path; polarity not fixed. |
| + (DC+) | Positive DC Output | Anode of internal upper diodes; delivers rectified positive output to filter capacitor or regulator. |
| – (DC–) | Negative DC Output / Ground Reference | Cathode of internal lower diodes; serves as return path and system ground reference point. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same 200V VRRM and 1.5A IO, but GBU package (larger footprint, higher RθJC = 100°C/W). | Requires larger PCB area and more thermal relief; less suitable for ultra-compact layouts. | Choose if legacy GBU footprint compatibility is required or higher surge margin (60A IFSM) is needed. |
| KBP202 (Comchip) | 200V VRRM, 2A IO, but higher VFM (1.1V) and no UL recognition. | Lacks UL E94661 listing; may require additional safety validation in certified end equipment. | Choose only for cost-sensitive, non-certified consumer applications where higher current headroom is prioritized. |
Compared with GBU2K and KBP202, W02G offers optimal balance of UL safety certification, compact WOG footprint, and thermal efficiency (84°C/W), making it preferred for space-constrained, safety-regulated industrial power supplies.

FAQ
What is the maximum allowable ambient temperature for continuous 1.5A operation?
At 1.5A DC output current, the W02G must be operated at ≤25°C ambient temperature to remain within its 150°C maximum junction temperature limit, assuming mounting on the specified 13×13mm PCB copper land. Derating is required above 25°C per Fig. 1; at 75°C ambient, maximum sustainable current drops to approximately 0.9A.
Does W02G support capacitive-input filter configurations?
Yes, but with mandatory 20% current derating per datasheet Note 1. For example, at 1.5A rated IO, only 1.2A average output current is permitted with capacitive input filters to prevent thermal runaway during cold-start inrush events.
Is the WOG package compatible with lead-free reflow soldering profiles?
Yes - the W02G features a lead-free, RoHS-compliant finish (DC 514+) and is qualified for standard Pb-free reflow processes. Its Moisture Sensitivity Level 1 rating eliminates pre-bake requirements, enabling direct placement into J-STD-020-compliant SMT lines.
What safety certifications does W02G hold?
W02G is UL Recognized under Component Index File E94661, confirming compliance with UL 60950-1 and UL 62368-1 for use in end equipment. It also meets RoHS Directive 2002/95/EC with glass and high-temperature solder exemptions applied per EU Annex Notes 5 and 7.
