Product details
Overview
2W01G from Diodes Incorporated is a 2.0A glass passivated bridge rectifier with 100V peak repetitive reverse voltage (VRRM), 1.1V forward voltage drop at 2.0A, and 60A non-repetitive surge current rating - used for AC-to-DC conversion in offline power supplies, LED drivers, and industrial control power stages.
For engineers reviewing the 2W01G datasheet, 2W01G pinout, 2W01G application, or 2W01G equivalent, key selection criteria include VRRM margin for line-voltage transients, thermal resistance (40°C/W) for PCB layout, IRM leakage at 125°C, and WOG package compatibility with through-hole reflow or wave soldering.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic WOG package. It operates under 60Hz resistive/inductive loads with mandatory 20% derating for capacitive loads per datasheet specification.
Thermal performance is defined with junction-to-case resistance of 40°C/W on a 13×13mm PCB copper land. Reverse leakage rises from 5.0μA at 25°C to 500μA at 125°C at rated DC blocking voltage, directly impacting standby power in low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum peak reverse voltage the device withstands without breakdown; sets minimum input AC voltage safety margin. |
| IO | 2.0 A - Average rectified output current at 25°C ambient; requires thermal derating above 25°C per Fig.1. |
| VFM | 1.1 V @ 2.0A - Forward voltage per element; determines conduction loss (2.2V total bridge drop) and thermal load. |
| IFSM | 60 A - Non-repetitive surge current (8.3ms half-sine); defines inrush tolerance during cold-start. |
| RθJC | 40 °C/W - Junction-to-case thermal resistance; used with heatsink or PCB copper area to calculate max operating temperature. |
| IRM | 5.0 μA @ 25°C / 500 μA @ 125°C - Peak reverse leakage; critical for high-impedance hold-up or low-quiescent circuits. |
| CT | 16 pF @ 1MHz - Typical total capacitance per element; affects EMI filtering and high-frequency switching noise. |

Applications
| LED Driver Power Supply | Industrial PLC Power Input |
|---|---|
Use Scenario: Converts 120/230VAC mains to unregulated DC for constant-current LED driver ICs in streetlight and high-bay fixtures. IC Role / Device Role / Timing Role: Primary AC/DC interface component; provides full-wave rectification before bulk capacitor and buck controller. Use Value: Low VFM (1.1V) minimizes conduction loss at 2A load, improving efficiency by ~0.8% over legacy 1.3V bridges; WOG package enables automated through-hole assembly. | Use Scenario: Powers 24VDC logic and I/O circuitry in programmable logic controllers exposed to factory floor voltage transients. IC Role / Device Role / Timing Role: Front-end rectifier in isolated auxiliary supply; interfaces with transformer secondary and downstream linear/LDO regulators. Use Value: 1500V isolation and 60A surge rating ensure immunity to 1kV ring-wave transients per IEC 61000-4-12; UL recognition simplifies panel builder certification. |
| AC-DC Adapter for Consumer Electronics | Motor Control Auxiliary Supply |
Use Scenario: Rectifies AC input in compact wall-wart adapters powering routers, set-top boxes, and IoT gateways. IC Role / Device Role / Timing Role: Input-stage bridge in flyback or buck-derived topologies; feeds primary-side capacitor and controller. Use Value: 100V VRRM provides 2× safety margin over 120VAC peak (170V); 16pF capacitance limits high-frequency EMI generation near switching nodes. | Use Scenario: Supplies isolated 15V bias rail for gate drivers and microcontrollers in 3-phase inverter modules. IC Role / Device Role / Timing Role: Secondary-side rectifier in auxiliary flyback or forward converter; delivers clean DC to isolated logic rails. Use Value: Low IRM (5μA @ 25°C) prevents excessive standby drain on hold-up capacitors; WOG footprint allows direct replacement of legacy DO-15 packages. |
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/100V rating, but GBU package (larger, 10.5mm height); RθJC = 35°C/W; IRM = 10μA @ 25°C. | Higher thermal performance but requires more board space; better for higher ambient temp (>60°C) designs. | Select when thermal headroom is constrained and PCB real estate permits larger footprint. |
| KBP201 (Shindengen) | 2A/100V, KBP package (4-pin inline); VFM = 1.05V; IFSM = 50A; UL recognized (E125977). | Lower forward drop improves light-load efficiency; lower surge rating limits use in high-inrush applications. | Select for cost-sensitive consumer adapters where inrush is controlled externally. |
Compared with GBU2K and KBP201, the 2W01G offers optimal balance of surge robustness (60A), compact WOG footprint, and UL/1500V isolation - making it preferred for space-constrained industrial and lighting power supplies where transient immunity is critical.

FAQ
Is 2W01G RoHS compliant and lead-free?
Yes, 2W01G is RoHS compliant with lead-free finish per EU Directive 2002/95/EC, effective for date codes 0514 and later. Exemptions for glass and high-temperature solder apply per Annex Notes 5 and 7. Full compliance documentation is available via Diodes Incorporated's quality portal.
What is the maximum operating temperature for 2W01G?
The 2W01G has an operating junction temperature range of –65°C to +150°C. At 25°C ambient, it supports 2.0A average output current; derating begins above 25°C per Figure 1, reaching ~1.2A at 75°C ambient with standard PCB mounting (13×13mm copper land).
Can 2W01G replace 2W005G in existing designs?
Yes, 2W01G is a direct functional upgrade from 2W005G (50V VRRM) with identical WOG package, pinout, and thermal characteristics. The higher 100V VRRM improves margin against line surges in 120VAC systems, while all other electrical parameters remain compatible.
Does 2W01G require heatsinking in typical applications?
No external heatsink is required for 2W01G at ≤2.0A and ≤25°C ambient when mounted on a 13×13mm PCB copper land (RθJC = 40°C/W). At higher currents or ambient temperatures, thermal design must account for total RθJA using PCB copper area and airflow per Diodes Application Note AP02007.
