Product details
Overview
PR1007G-T from Diodes Incorporated is a 1.0A fast recovery glass passivated rectifier diode in DO-41 package, rated for 1000V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 1.0A (VFM), and 150ns reverse recovery time (tRR), used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR1007G-T datasheet, PR1007G-T pinout, PR1007G-T application, or PR1007G-T equivalent, key selection criteria include its 1000V blocking capability, 30A non-repetitive surge rating, low 5.0µA reverse leakage at 25°C, RoHS-compliant tin-plated leads, and thermal resistance of 95°C/W for ambient-limited designs.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-voltage, medium-current switching applications. Its glass passivated die construction ensures stable performance under thermal cycling and humidity exposure, while the fast recovery (150ns) enables efficient operation in 50/60Hz and higher-frequency line-frequency rectifiers.
The DO-41 axial package supports manual and automated through-hole assembly, with cathode band polarity marking and 0.35g mass. Electrical derating follows standard curves: 1.0A average current at +55°C ambient, reduced to ~0.6A at +100°C, and surge withstand up to 30A (8.3ms half-sine) without failure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input range up to 700V RMS. |
| IO @ TA=55°C | 1.0 A - Continuous DC output current with leads held at ambient at 9.5mm from case; sets minimum heatsinking requirement. |
| VFM @ IF=1.0A | 1.3 V - Forward conduction loss at rated current; contributes ~1.3W dissipation in linear regulation or unregulated supplies. |
| tRR | 150 ns - Reverse recovery time measured at IF=0.5A, IR=1.0A, IRR=0.25A; limits usable frequency in flyback snubbers and PFC stages. |
| IRM @ 25°C | 5.0 µA - Reverse leakage at full blocking voltage; critical for high-impedance bias networks and low-power standby circuits. |
| RθJA | 95 °C/W - Junction-to-ambient thermal resistance; determines temperature rise under 1.3W dissipation without heatsink. |
| IFSM | 30 A - Single-cycle surge rating; withstands inrush into capacitive loads or cold-start conditions in offline SMPS. |
Pinout & Package
DO-41 plastic axial package with cathode band marking; lead finish is matte tin, solderable per MIL-STD-202 Method 208. Case meets UL 94V-0 flammability rating and J-STD-020 Level 1 moisture sensitivity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive input terminal during forward conduction | Connected to AC source or transformer secondary; carries full load current during positive half-cycle. |
| Cathode | Negative output terminal during forward conduction | Marked with band; connects to bulk capacitor or downstream regulator; defines output polarity in bridge or single-diode configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates need for hermetic sealing; provides stable reverse characteristics over 150°C operating range and >1000hr HAST reliability. |
| Fast recovery (150ns) | Reduces switching losses in line-frequency rectifiers operating above 1kHz ripple content; avoids hard reverse recovery in quasi-resonant topologies. |
| 30A surge rating | Supports direct connection to 120/230VAC mains without external NTC thermistor in low-cost LED driver and adapter designs. |
| RoHS-compliant tin plating | Enables lead-free reflow and wave soldering; eliminates post-process cleaning for high-volume manufacturing. |
Applications
| Industrial Power Supply Input Stage | LED Driver Bulk Rectification |
|---|---|
Use Scenario: Full-wave rectification of 230VAC mains input feeding a 350V bulk capacitor in open-frame industrial power supplies. IC Role / Device Role / Timing Role: Unidirectional current valve enabling DC bus generation; no timing function but defines conduction window via AC phase alignment. Use Value: 1000V VRRM prevents breakdown during line surges; 150ns tRR minimizes EMI from reverse recovery spikes in unshielded enclosures. | Use Scenario: Single-phase half-wave rectification in cost-sensitive constant-current LED drivers for street lighting. IC Role / Device Role / Timing Role: High-voltage anode-side switch converting AC line to pulsating DC; operates at 50/60Hz with no active control. Use Value: 30A IFSM absorbs lamp cold-filament inrush; 5.0µA IRM preserves standby power budget below 100mW. |
| AC-DC Adapter Output Protection | Motor Control Auxiliary Supply |
Use Scenario: Output-side reverse polarity protection in universal-input wall adapters powering IoT sensors and controllers. IC Role / Device Role / Timing Role: Series-blocking diode preventing backfeed from battery or supercapacitor backup sources. Use Value: 1.3V VFM limits voltage drop across protection path; DO-41 mechanical robustness survives repeated plug insertion cycles. | Use Scenario: Auxiliary 24V DC supply generation from 3-phase motor drive bus using three PR1007G-T diodes in half-wave configuration. IC Role / Device Role / Timing Role: Voltage clamping and rectification element in auxiliary power module; handles intermittent 600V transients. Use Value: 95°C/W RθJA allows operation at 75°C ambient without heatsink; glass passivation resists contamination in dusty motor environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1M-T | Same DO-41 package, 1000V VRRM, but 500ns tRR and 1.4V VFM at 1.0A. | Higher recovery loss limits use in high-ripple or high-frequency auxiliary supplies. | Select RS1M-T only when cost is primary constraint and 150ns tRR is not required for EMI compliance. |
| 1N4007G | Same DO-41, 1000V VRRM, but 30µA IRM at 25°C and 2.0µs tRR - standard recovery, not fast. | Unsuitable for designs requiring low reverse recovery charge (Qrr) or low EMI emission. | Choose 1N4007G only for purely resistive loads or low-frequency (<1kHz) applications where efficiency and noise are non-critical. |
Compared with RS1M-T and 1N4007G, PR1007G-T delivers superior dynamic performance (150ns vs. 500ns/2000ns tRR) and lower leakage (5.0µA vs. 5.0µA/30µA), making it optimal for EMI-sensitive, high-reliability industrial rectification where thermal margin and surge immunity are design priorities.

FAQ
What is the maximum junction temperature for continuous operation of PR1007G-T?
The PR1007G-T has an operating junction temperature range of –65°C to +150°C. For continuous operation at 1.0A average current, thermal design must ensure TJ remains ≤150°C - typically achieved by limiting ambient temperature to ≤55°C with leads held at ambient at 9.5mm from case, per Note 4 in DS27001 Rev. 12–3.
Is PR1007G-T suitable for use in a full-wave bridge configuration?
Yes - PR1007G-T is a single discrete diode and can be used in full-wave bridge configurations when four units are assembled. Its 1000V VRRM and 30A IFSM make it appropriate for 230VAC input bridges; however, thermal coupling between diodes must be managed to avoid exceeding RθJA-limited dissipation in compact layouts.
Does PR1007G-T have halogen-free or "Green" material status?
Yes - PR1007G-T complies with Diodes Incorporated's "Green" definition: it is halogen-free and antimony-free per their quality documentation, and fully RoHS 3 compliant (2015/863/EU), including all applicable exemptions. Full material declarations are available upon request via Diodes' website.
How does the 150ns reverse recovery time impact EMI in a 50Hz rectifier design?
The 150ns tRR reduces high-frequency spectral content during reverse recovery compared to standard recovery diodes (e.g., 1N4007G at 2µs), lowering radiated EMI in unshielded enclosures. In 50Hz designs, this primarily benefits conducted EMI filtering - allowing smaller X/Y capacitors and simpler choke designs while meeting CISPR-22 Class B limits.
