Product details
Overview
PR1002G-T from Diodes Incorporated is a 1.0A fast recovery glass passivated rectifier diode in DO-41 package, rated for 100V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 1.0A (VFM), and 150ns reverse recovery time (tRR). It delivers low reverse leakage (5.0µA at 25°C), handles 30A non-repetitive surge current, and is RoHS-compliant with tin-plated leads.
For engineers reviewing the PR1002G-T datasheet, PR1002G-T pinout, PR1002G-T application, or PR1002G-T equivalent, key selection criteria include its 100V blocking capability, fast 150ns recovery for switching power supplies, thermal resistance of 95°C/W, DO-41 mechanical compatibility, and suitability for AC/DC front-end rectification where efficiency and surge robustness are critical.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-frequency switching applications. Its glass passivated die construction ensures stable junction protection and low IRM, while the 150ns tRR enables use in 20–100kHz SMPS designs without excessive switching loss.
The DO-41 package supports lead-free soldering per MIL-STD-202 Method 208, with polarity indicated by cathode band marking. Thermal derating follows a defined curve: full 1.0A IO is rated at TA = +55°C, dropping to ~0.7A at +100°C ambient under standard mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage the diode blocks reliably in circuit |
| IO @ TA=55°C | 1.0 A - Continuous average forward current rating under specified thermal condition |
| VFM @ IF=1.0A | 1.3 V - Forward conduction loss impacting efficiency and thermal rise in rectifier stage |
| tRR | 150 ns - Reverse recovery time determining minimum switching frequency limit and EMI generation |
| IFSM (8.3ms) | 30 A - Surge withstand capability 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 - Junction-to-ambient thermal resistance defining heatsinking requirements |
Pinout & Package
DO-41 plastic package with axial leads: cathode identified by band-marked end; anode at opposite lead. Molded UL 94V-0 plastic case, 0.35g weight, tin-plated solderable terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary side; must withstand peak inverse voltage during off-state |
| Cathode | Forward current exit point | Connected to output capacitor or load; polarity band identifies this terminal for correct PCB orientation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhanced junction reliability and moisture resistance vs. epoxy-passivated alternatives |
| Fast 150ns recovery | Enables efficient operation in 50–100kHz flyback and forward converters |
| 30A surge rating | Withstands 8.3ms half-sine surges common in AC mains input stages without failure |
| Low 5.0µA IRM | Minimizes power loss in high-voltage hold-up or sensing circuits at elevated temperatures |
Applications
| AC/DC Adapter Input Stage | Industrial Power Supply Rectification |
|---|---|
Use Scenario: 5–24W wall adapter converting 90–264VAC to 5–12VDC using single-phase bridge or voltage-doubler topology. IC Role / Device Role / Timing Role: Primary-side rectifier handling full-line input current and transient surges. Use Value: 100V VRRM safely covers 1.4×264VAC peak (373V) with margin when used in doubler; 150ns tRR reduces switching loss vs. general-purpose rectifiers. | Use Scenario: 24–48V industrial DC power module accepting universal AC input with active PFC pre-regulator. IC Role / Device Role / Timing Role: Secondary-side output rectifier in isolated DC/DC stage operating at 65–100kHz. Use Value: 1.3V VFM limits conduction loss at 1A load; DO-41 footprint allows manual or automated through-hole assembly in ruggedized enclosures. |
| LED Driver Bulk Rectification | Automotive Auxiliary Power Module |
Use Scenario: Non-isolated LED driver for street lighting, rectifying 230VAC before buck conversion. IC Role / Device Role / Timing Role: High-voltage input rectifier in capacitive-input filter configuration. Use Value: 30A IFSM accommodates cold-start inrush into large bulk capacitors; low IRM prevents leakage-induced dimming drift over temperature. | Use Scenario: 12V auxiliary supply in commercial vehicle electronics, fed from alternator output (13.5–16V nominal, up to 36V transients). IC Role / Device Role / Timing Role: Reverse-polarity protection and input rectification in dual-battery interface circuit. Use Value: Cathode-band polarity marking ensures fail-safe installation; RoHS-compliant tin plating meets automotive soldering and corrosion standards. |
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 1000V VRRM but higher 1.3V VFM and 500ns tRR | Slower recovery increases switching loss above 30kHz; better suited for line-frequency rectification | Select RS1M-T only if cost sensitivity outweighs high-frequency efficiency needs |
| 1N4934G | 100V VRRM, 1.2V VFM, but 250ns tRR and no glass passivation | Higher IRM (50µA) and reduced humidity resistance limit use in sealed outdoor enclosures | Prefer 1N4934G only in cost-constrained consumer products with short lifetime expectations |
Compared with RS1M-T and 1N4934G, PR1002G-T uniquely balances 150ns speed, 5.0µA leakage, and glass passivation-making it optimal for compact, thermally constrained, medium-frequency SMPS where long-term reliability matters.

FAQ
What is the maximum operating temperature for PR1002G-T?
The PR1002G-T has an operating junction temperature range of –65°C to +150°C. Its ambient temperature rating is limited to +55°C for full 1.0A average forward current, based on standard DO-41 mounting with 9.5mm lead length at ambient. Derating curves show usable current drops to approximately 0.7A at +100°C ambient.
Is PR1002G-T compatible with lead-free reflow soldering?
PR1002G-T features tin-plated leads compliant with MIL-STD-202 Method 208 and is rated for lead-free soldering. While DO-41 is primarily intended for wave or hand soldering, it withstands peak reflow temperatures up to 260°C for 10 seconds. Thermal shock testing confirms reliability under JEDEC J-STD-020 Level 1 moisture sensitivity conditions.
How does PR1002G-T differ from PR1001G-T?
PR1002G-T differs from PR1001G-T solely in peak repetitive reverse voltage rating: PR1002G-T is rated for 100V VRRM, while PR1001G-T is rated for 50V. All other parameters-including IO, VFM, tRR, IFSM, IRM, and package-are identical. The devices share the same DO-41 outline, marking format, and thermal characteristics.
Can PR1002G-T be used in place of a Schottky diode?
No-PR1002G-T is a PN-junction fast recovery diode, not a Schottky. It has higher VFM (1.3V vs. typical 0.4–0.6V for Schottkys) and slower tRR (150ns vs. <10ns), making it unsuitable for ultra-low-loss or very high-frequency (>200kHz) applications. Use only where its 100V rating, surge robustness, and cost advantage justify the trade-off in conduction and switching loss.
