Product details
Overview
PR1004G-T from Diodes Incorporated is a 1.0A fast recovery glass passivated rectifier diode in DO-41 package, rated for 400V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 1.0A (VFM), and 150ns reverse recovery time (tRR), used in AC/DC input stage rectification for offline power supplies and auxiliary power rails.
For engineers reviewing the PR1004G-T datasheet, PR1004G-T pinout, PR1004G-T application, or PR1004G-T equivalent, key selection criteria include VRRM derating margin, thermal resistance (RθJA = 95°C/W), surge capability (IFSM = 30A), low IRM (5.0µA @ 25°C), and DO-41 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching-mode power supply (SMPS) front-end stages. Its fast recovery (tRR = 150ns) minimizes switching losses during commutation, while glass passivation ensures stable surface leakage performance under humid or contaminated conditions.
The DO-41 package supports axial lead mounting with defined thermal path to ambient (RθJA = 95°C/W under specified lead length condition), and its 400V VRRM rating targets universal-input (85–265VAC) offline converters where 2x peak line voltage plus safety margin dictates minimum blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Sustains peak reverse voltage up to 400V without breakdown; suitable for 230VAC mains-derived designs with 2×VPEAK + margin |
| IO @ TA=55°C | 1.0 A - Continuous average forward current rating at 55°C ambient; requires heatsinking or airflow above this temperature |
| VFM @ IF=1.0A | 1.3 V - Forward conduction loss per diode; contributes ~1.3W dissipation at full load, impacting efficiency and thermal design |
| tRR | 150 ns - Fast reverse recovery enables use in 50–100kHz SMPS without excessive switching loss or EMI from tail current |
| IFSM (8.3ms) | 30 A - Withstands single half-sine surge events such as cold-start inrush or lightning-induced transients on AC line |
| IRM @ 25°C | 5.0 µA - Low leakage preserves hold-up capacitor charge during standby and reduces no-load power consumption |
| RθJA | 95 °C/W - Thermal resistance from junction to ambient under standard test condition (9.5mm lead length); defines max power before thermal runaway |
Pinout & Package
DO-41 plastic package with axial leads; cathode identified by band marking. Case meets UL 94V-0 flammability rating and J-STD-020 moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must withstand full reverse voltage when cathode is biased higher |
| Cathode | Forward current exit point | Connected to output capacitor or bulk DC rail; polarity band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Eliminates surface contamination-induced leakage drift; maintains stable IRM over time and humidity exposure |
| Fast switching (tRR = 150ns) | Reduces reverse recovery charge (Qrr), lowering EMI and conduction loss in high-frequency rectifier applications |
| 30A non-repetitive surge rating | Supports robust operation during AC line surges without catastrophic failure, reducing need for upstream fusing |
| RoHS-compliant lead finish | Tin-plated leads meet MIL-STD-202 solderability requirements and eliminate Pb-based assembly concerns |
| Low thermal resistance (RθJA = 95°C/W) | Enables 1.0A operation at 55°C ambient without forced cooling, simplifying thermal management in compact adapters |
Applications
| AC/DC Adapter Input Rectification | Industrial Control Power Supply |
|---|---|
Use Scenario: 12V/1A wall adapter converting 85–265VAC to DC using bridge or single-diode configuration. IC Role / Device Role / Timing Role: Primary rectifier conducting during positive half-cycle; blocks reverse voltage during negative half-cycle. Use Value: 400V VRRM provides 2× margin over 265VAC peak (375V), ensuring reliability across global mains voltages. | Use Scenario: Auxiliary 5V/12V rail generation in PLC I/O modules powered from 24VDC or 120VAC inputs. IC Role / Device Role / Timing Role: Standby rectifier feeding linear regulator or buck converter; operates continuously at partial load. Use Value: 5.0µA IRM at 25°C minimizes standby current draw, extending system uptime during brownout conditions. |
| LED Driver Bulk Rectification | Appliance Main Power Conversion |
Use Scenario: Off-line LED driver for commercial lighting, rectifying AC before PFC and DC/DC stages. IC Role / Device Role / Timing Role: Input-stage diode in voltage-doubler or bridge configuration; handles 50/60Hz line frequency conduction.

IC Role / Device Role / Timing Role: High-reliability rectifier exposed to noisy, high-surge industrial AC lines. Use Value: 30A IFSM rating withstands repeated compressor or relay turn-on surges without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1J-T | VRRM = 600V, tRR = 250ns, VFM = 1.3V, same DO-41 package | Higher blocking voltage but slower recovery; better for 277VAC lighting systems | Select RS1J-T if >400V margin required; accept 100ns longer tRR for improved surge margin |
| 1N4937 | VRRM = 600V, tRR = 200ns, VFM = 1.2V, DO-41, IFSM = 30A | Lower VFM and faster than PR1004G-T but not RoHS-compliant (lead-bearing) | Choose 1N4937 only for legacy non-RoHS production; verify compliance requirements first |
Compared with RS1J-T and 1N4937, PR1004G-T offers optimal balance of 400V rating, 150ns speed, and RoHS compliance for cost-sensitive universal-input adapters-where lower VRRM reduces junction capacitance (CT = 15pF) and improves high-frequency noise immunity.

FAQ
What is the maximum operating temperature for PR1004G-T?
The PR1004G-T has an operating junction temperature range of –65°C to +150°C. Its safe continuous operation at 1.0A average current is limited to 55°C ambient temperature unless additional heatsinking or airflow is applied, due to its 95°C/W thermal resistance and 1.3W typical power dissipation at full load.
Is PR1004G-T compatible with lead-free reflow soldering?
Yes, PR1004G-T features tin-plated leads compliant with RoHS and solderable per MIL-STD-202, Method 208. It supports standard lead-free reflow profiles (peak 260°C), though its DO-41 axial package is typically hand-soldered or wave-soldered-not reflowed-due to thermal mass and lead geometry.
How does PR1004G-T compare to standard recovery rectifiers like 1N4007?
PR1004G-T offers 150ns reverse recovery versus 30µs for 1N4007, enabling efficient operation above 20kHz. It also delivers lower forward voltage (1.3V vs. ~1.1V at low current but significantly higher at 1A), reduced leakage (5µA vs. ~50µA), and tighter VRRM tolerance-making it suitable for modern switch-mode, not linear, power supplies.
Can PR1004G-T be used in parallel for higher current handling?
No-parallel operation is not recommended without individual series resistors or active current balancing. Mismatches in VFM and thermal coupling cause current hogging; the device's 1.0A rating assumes single-device operation with defined thermal conditions. For >1A, select a higher-current part like PR2004G-T or use a multi-phase topology.
