Product details
Overview
PR2004G-T from Diodes Incorporated is a 2.0A fast recovery glass passivated rectifier diode in DO-15 package, rated for 400V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 2.0A, and 150ns reverse recovery time - deployed in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR2004G-T datasheet, PR2004G-T pinout, PR2004G-T application, or PR2004G-T equivalent, key selection criteria include VRRM derating margin, thermal resistance (50°C/W), surge capability (80A IFSM), and low IRM (5.0mA @25°C) for high-reliability offline rectification.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching power conversion. Its glass passivation ensures stable junction integrity under thermal cycling, while the DO-15 axial leaded package supports through-hole mounting with 0.4g mass and UL 94V-0 flammability rating.
The 150ns reverse recovery time (trr) enables operation in 20–100kHz SMPS topologies without excessive switching loss, and its 50°C/W junction-to-ambient thermal resistance requires heatsinking only above ~1.2A continuous conduction in still air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum non-repetitive reverse voltage before breakdown; sets minimum input AC peak withstand for 230VAC systems. |
| IO @ TA=55°C | 2.0 A - Continuous average forward current with leads held at ambient at 9.5mm from case; defines usable DC output capacity. |
| VFM @ IF=2.0A | 1.3 V - Forward voltage drop determining conduction loss (2.6W max at full load) and thermal rise. |
| IFSM (8.3ms) | 80 A - Non-repetitive surge rating; supports cold-start inrush into capacitive inputs without failure. |
| trr | 150 ns - Reverse recovery time measured at IF=0.5A/IR=1.0A/Irr=0.25A; limits switching frequency and EMI in flyback converters. |
| IRM @25°C | 5.0 mA - Peak reverse leakage at rated DC blocking voltage; impacts standby power in no-load conditions. |
| RθJA | 50 °C/W - Junction-to-ambient thermal resistance; used to calculate junction temperature rise (ΔTj = Pd × RθJA). |
Pinout & Package
DO-15 package: axial-leaded, molded plastic case with cathode band marking; polarity indicated by single black band on cathode end; leads tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to AC input or transformer secondary; must handle full surge current and thermal stress. |
| Cathode (banded end) | Forward current exit / reverse blocking node | Connected to bulk capacitor or output rail; reverse voltage rating applies across this terminal and anode. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Prevents moisture ingress and metallization corrosion, enabling >10-year field reliability in humid industrial environments. |
| Surge overload rating to 80A peak | Withstands 8.3ms half-sine surges - sufficient for 230VAC line transients and capacitor charging spikes. |
| Low reverse leakage (5.0mA @25°C) | Minimizes standby power loss in energy-sensitive applications such as LED lighting and IoT power adapters. |
| Fast switching (150ns trr) | Reduces reverse recovery loss and associated EMI in 50–100kHz flyback and forward converters. |
Applications
| AC/DC Power Adapter Input Stage | Industrial Motor Drive Front-End Rectifier |
|---|---|
Use Scenario: 230VAC-to-DC conversion feeding a 24V/2A isolated flyback supply in wall-mounted smart home gateways. IC Role / Device Role / Timing Role: Primary-side unidirectional rectifier converting AC line to pulsating DC prior to bulk capacitor filtering. Use Value: 400V VRRM provides 1.7× margin over 230VAC peak (325V), and 150ns trr prevents excessive switching loss at 65kHz operation. | Use Scenario: Single-phase rectification of 220VAC control power for PLC I/O modules operating in factory-floor cabinets. IC Role / Device Role / Timing Role: Half-wave rectifier supplying auxiliary 12V logic rails; mounted directly on PCB with minimal heatsinking. Use Value: 2.0A IO rating sustains continuous load under 55°C ambient, and 80A IFSM absorbs motor contactor coil de-energization spikes. |
| LED Driver Bulk Rectification | UPS Battery Charger Input Stage |
Use Scenario: Off-line LED driver for commercial downlights using bridge configuration with four PR2004G-T devices. IC Role / Device Role / Timing Role: One leg of full-wave bridge rectifier converting 120/230VAC to DC bus for constant-current LED regulation. Use Value: 1.3V VFM ensures <1.5W conduction loss per diode at 2A, limiting thermal rise without forced airflow. | Use Scenario: Input rectifier in 48V battery charger for telecom backup systems handling 200–240VAC mains. IC Role / Device Role / Timing Role: Half-wave rectifier feeding SCR-controlled charging circuit; exposed to frequent line interruptions and surges. Use Value: Glass passivation and 80A IFSM ensure survival during repeated grid dropout/recovery events with high dv/dt. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same 400V VRRM, 2A IO, but TO-220AC package; higher thermal mass, lower RθJA (25°C/W). | Requires PCB footprint change and screw-mount heatsink; better for >1.5A continuous conduction in enclosed enclosures. | Select when thermal management dominates over board space or cost; not drop-in compatible. |
| ON Semi MUR220 | 200V VRRM, same DO-15 package and 2A IO; 100ns trr, lower VFM (1.15V), but insufficient for 230VAC systems. | Limited to 115VAC or DC-fed applications; unsuitable where 400V isolation margin is required. | Only viable in 100–120VAC markets or low-voltage DC-DC pre-regulators. |
Compared with STTH2R04 and MUR220, PR2004G-T uniquely balances 400V isolation margin, DO-15 mountability, and 150ns trr for cost-sensitive, space-constrained 230VAC offline supplies - making it optimal where leaded reliability and legacy compatibility outweigh thermal or speed extremes.

FAQ
What is the maximum allowable junction temperature for PR2004G-T?
The absolute maximum junction temperature is +150°C, as specified in the datasheet's operating temperature range (Tj = –65°C to +150°C). Derating begins at +55°C ambient for the 2.0A average current rating, and sustained operation above 125°C requires thermal modeling using RθJA = 50°C/W and actual power dissipation.
Can PR2004G-T be used in a full-wave bridge configuration?
Yes - PR2004G-T is commonly used in discrete full-wave bridge rectifiers. Four units provide 400V VRRM, 2.0A IO per leg, and matched trr characteristics. Ensure symmetrical PCB layout and equal thermal exposure to avoid current imbalance; no internal series connection or integrated bridge functionality exists.
Is PR2004G-T RoHS compliant and lead-free?
Yes - PR2004G-T features lead-free terminations and complies with RoHS Directive 2011/65/EU (Revision 13.2.2003), including exemptions for glass and high-temperature solder per EU Directive Annex Notes 5 and 7. Tin-plated leads meet MIL-STD-202 Method 208 solderability requirements.
How does reverse recovery time affect EMI in switch-mode designs?
At 150ns, PR2004G-T's trr generates measurable high-frequency ringing during turn-off, especially with parasitic inductance in PCB traces. This contributes to conducted EMI in the 1–30MHz band; adding a small RC snubber (e.g., 100Ω + 100pF) across the diode reduces peak dv/dt and suppresses noise without significantly impacting efficiency.
