Product details
Overview
PR1005G-T from Diodes Incorporated is a 1.0A fast recovery glass passivated rectifier diode in DO-41 package, rated for 600V 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 of offline power supplies and auxiliary power rails.
For engineers reviewing the PR1005G-T datasheet, PR1005G-T pinout, PR1005G-T application, or PR1005G-T equivalent, key selection criteria include its 600V blocking capability, 30A non-repetitive surge rating, low 5.0µA reverse leakage at 25°C, DO-41 mechanical compatibility, and RoHS-compliant tin-plated leads for reflow and wave soldering.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching power conversion. Its glass passivated die construction ensures stable performance under thermal cycling, while the fast recovery characteristic (tRR = 150ns) minimizes switching losses in 50/60Hz and higher-frequency line-frequency rectification circuits.
The DO-41 package provides standardized axial lead mounting with 95°C/W junction-to-ambient thermal resistance when leads are held at ambient temperature at 9.5mm from case. It supports average forward current of 1.0A at +55°C ambient, derated to zero at +150°C per the published derating curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum peak reverse voltage the diode blocks without breakdown in repetitive operation |
| IO @ TA=+55°C | 1.0 A - Continuous average forward current rating under specified thermal conditions |
| VFM @ IF=1.0A | 1.3 V - Forward conduction loss contributing directly to power dissipation in rectifier stage |
| tRR | 150 ns - Time required to transition from forward conduction to reverse blocking, limiting switching frequency suitability |
| IFSM (8.3ms) | 30 A - Surge current handling capacity during line transients or inrush events |
| IRM @ 25°C | 5.0 µA - Reverse leakage current affecting standby power and high-impedance bias networks |
| RθJA | 95 °C/W - Thermal resistance defining junction temperature rise above ambient per watt of power dissipated |
Pinout & Package
DO-41 plastic package with axial leads: cathode identified by band-marked end; anode at opposite lead. Case meets UL 94V-0 flammability rating and J-STD-020 moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked lead) | Forward current entry point | Connected to AC source or transformer secondary winding during positive half-cycle |
| Cathode (banded lead) | Forward current exit point | Connected to output capacitor or load return path; defines polarity of DC output |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances long-term reliability and moisture resistance versus epoxy-passivated alternatives |
| Fast recovery (150ns) | Reduces reverse recovery charge and associated switching losses in line-frequency applications |

Applications
| AC/DC Adapter Input Stage | Industrial Control Power Supply |
|---|---|
Use Scenario: Rectifying 50/60Hz AC from wall outlet or transformer secondary into unregulated DC bus. IC Role / Device Role / Timing Role: Unidirectional current valve enabling half-wave or full-wave bridge operation. Use Value: 600V VRRM safely handles 230VAC mains with margin; 1.0A IO sustains typical adapter loads up to 12W. | Use Scenario: Providing isolated auxiliary power for PLC I/O modules and sensor interfaces. IC Role / Device Role / Timing Role: Primary-side rectifier in flyback or forward converter auxiliary winding circuit. Use Value: 150ns tRR limits switching loss in 60–100kHz auxiliary supplies; DO-41 fits standard through-hole footprints. |

Use Value: Glass passivation withstands humid environments; 30A IFSM accommodates motor startup surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1M-T | Same DO-41 package, identical 1.0A/600V ratings, but tRR = 500ns (slower recovery) | Lower switching loss criticality; acceptable where EMI or efficiency is less constrained | Select RS1M-T only if system operates below 20kHz and reverse recovery noise is not regulated |
| 1N4007G | 600V VRRM, 1.0A IO, but tRR > 2µs (standard recovery); higher VFM (~1.55V) | Cost-sensitive, non-switching applications with minimal di/dt demands | Use 1N4007G only in purely 50/60Hz linear supplies where efficiency and EMI are non-critical |
Compared with RS1M-T and 1N4007G, PR1005G-T delivers superior dynamic performance (150ns tRR) and lower conduction loss (1.3V VFM), making it preferred for compact, thermally constrained, or higher-frequency auxiliary supplies requiring tighter regulation and lower standby power.

FAQ
What is the maximum operating temperature for PR1005G-T?
The PR1005G-T has an operating and storage temperature range of –65°C to +150°C. Its 1.0A average forward current rating is specified at +55°C ambient; derating follows the published curve, reaching zero current at +150°C with leads maintained at ambient at 9.5mm from case.
Is PR1005G-T compatible with lead-free reflow soldering?
Yes. PR1005G-T features tin-plated leads compliant with RoHS directives and qualified for lead-free reflow soldering per JEDEC J-STD-020. Its moisture sensitivity level is Class 1, eliminating bake requirements prior to assembly.
How does PR1005G-T differ from PR1004G-T?
PR1005G-T is rated for 600V VRRM and 420V VR(RMS), whereas PR1004G-T is rated for 400V VRRM and 280V VR(RMS). All other parameters-including IO, VFM, tRR, and package-are identical. The higher voltage rating makes PR1005G-T suitable for 230VAC mains with safety margin.
Can PR1005G-T be used in full-wave bridge configurations?
Yes. As a single-junction axial diode in DO-41 package, PR1005G-T is commonly used in discrete full-wave bridge rectifiers (e.g., four units per bridge). Its 30A IFSM and 150ns tRR support reliable operation in both half-wave and full-wave topologies with resistive, inductive, or capacitive loads.
