Product details
Overview
2W02G from Diodes Incorporated is a 2.0A glass passivated bridge rectifier with 200V peak repetitive reverse voltage (VRRM), 1.1V forward voltage at 2.0A, and 60A non-repetitive surge current capability; used for AC-to-DC conversion in offline power supplies, LED drivers, and industrial control power stages.
For engineers reviewing the 2W02G datasheet, 2W02G pinout, 2W02G application, or 2W02G equivalent, key selection criteria include VRRM rating, thermal resistance (40°C/W), case isolation voltage (1500V), RoHS compliance (lead-free finish), and WOG package suitability for PCB mounting.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic WOG molded plastic package with silver-plated leads. It operates under 60Hz resistive/inductive loads and requires 20% current derating for capacitive loads.
Thermal performance is defined with 13×13mm PCB copper land areas; junction-to-case thermal resistance is 40°C/W. Reverse leakage is specified at 5.0μA @ 25°C and 500μA @ 125°C at rated DC blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage the device blocks without breakdown; sets minimum input AC voltage headroom. |
| IO | 2.0 A - Average rectified output current at 25°C ambient; defines continuous DC output capability per design. |
| VFM | 1.1 V @ 2.0A - Forward voltage drop per diode pair; directly impacts conduction loss and thermal load in power stage. |
| IFSM | 60 A - Non-repetitive surge current tolerance for 8.3ms half-sine wave; determines inrush withstand in transformer-coupled supplies. |
| RθJC | 40 °C/W - Junction-to-case thermal resistance; enables thermal interface design when mounted on PCB with specified 13×13mm copper area. |
| Isolation Voltage | 1500 V - Case-to-terminal isolation rating; satisfies basic insulation requirements for Class II AC/DC converters. |

Key Features
| Feature | Design Value |
|---|---|

| 1500V case-to-terminal isolation | Meets reinforced insulation requirements for double-insulated AC/DC power supplies without additional creepage/clearance barriers. |
| UL Recognized Component (E94661) | Validates safety compliance for end-equipment certification (e.g., IEC 62368-1) without requiring retesting of the rectifier itself. |
| Lead-free, RoHS-compliant finish (Date Code 0514+) | Enables compliance with EU RoHS Directive 2002/95/EC and supports lead-free reflow soldering processes. |
Applications
| LED Driver Power Supply | Industrial PLC Power Stage |
|---|---|
|
Use Scenario: Converts 120/230VAC mains to unregulated DC for constant-current LED driver ICs in commercial lighting fixtures. IC Role / Device Role / Timing Role: Primary AC/DC rectification stage; provides isolated, ripple-rich DC bus prior to bulk capacitance and switching regulation. Use Value: 200V VRRM accommodates 230VAC +10% line surges; 60A IFSM handles inrush from large input X-capacitors. |
Use Scenario: Supplies auxiliary 24VDC logic power in programmable logic controller (PLC) backplanes operating in factory environments. IC Role / Device Role / Timing Role: Off-line bridge rectifier feeding linear or buck regulator; must survive voltage transients and temperature cycling. Use Value: 1500V isolation and –65°C to +150°C operating range ensure robustness across industrial ambient extremes and EMC events. |
| Appliance Control Board | AC Fan Speed Controller |
|
Use Scenario: Powers microcontroller and relay drivers in white goods (e.g., washing machine control modules) using split-phase 120VAC input. IC Role / Device Role / Timing Role: Mains-side rectification before 5V/3.3V LDO or DC/DC converter; subject to frequent on/off cycling. Use Value: Glass passivation prevents corrosion-induced failure during high-humidity storage or condensation exposure in laundry environments. |
Use Scenario: Rectifies phase-controlled AC to variable DC for triac-driven universal motor speed control in HVAC blowers. IC Role / Device Role / Timing Role: Full-wave bridge handling discontinuous conduction mode (DCM) and high dv/dt from triac commutation. Use Value: Low 1.1V VFM minimizes heat generation during partial-conduction operation; WOG package allows compact SMT-compatible layout. |
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 2A/200V rating, but GBU package (larger footprint, higher RθJC = 50°C/W). | Requires larger PCB area and more thermal copper; less suitable for space-constrained designs. | Prefer where legacy GBU footprint compatibility is required and thermal margin exists. |
| KBP202 (Shindengen) | Identical WOG package, same VRRM/IO, but slightly higher VFM (1.15V) and lower IFSM (50A). | Lower surge rating may require upstream fusing in high-inrush applications. | Acceptable where surge stress is low and supply chain diversification is prioritized. |
Compared with GBU2K and KBP202, the 2W02G offers superior thermal resistance (40°C/W vs. 50°C/W) and highest surge rating (60A), making it optimal for compact, high-reliability AC/DC front-ends where thermal headroom and transient robustness are critical.

FAQ
Is the 2W02G RoHS compliant and lead-free?
Yes, the 2W02G features a lead-free finish and is RoHS compliant per EU Directive 2002/95/EC for date codes 0514 and later. The plating meets MIL-STD-202 Method 208 for solderability, and exemptions for high-temperature solder and glass are applied per Annex Notes 5 and 7 of the directive.
What is the maximum ambient temperature for full 2.0A operation?
Full 2.0A average output current is rated at TA = 25°C. As shown in Figure 1 of the datasheet, current must be linearly derated above 25°C - e.g., to approximately 1.3A at 75°C ambient - based on the forward current derating curve for single-phase, half-sine-wave 60Hz loading.
Can the 2W02G replace the 2W01G in an existing design?
Yes, the 2W02G is a direct upgrade from the 2W01G (100V VRRM) with identical WOG package, pinout, and thermal characteristics, offering higher reverse voltage margin. No layout or thermal redesign is needed, but verify that the increased VRRM does not affect snubber or clamping circuit behavior.
Why is the 2W02G marked "NOT RECOMMENDED FOR NEW DESIGN"?
This designation reflects Diodes Incorporated's internal product lifecycle guidance, indicating newer alternatives (e.g., higher-efficiency or smaller-footprint bridges) are preferred for new projects. The 2W02G remains fully qualified, in active production, and supported for existing designs and legacy replacements.
