Product details
Overview
PR1507G-T from Diodes Incorporated is a 1.5A, 1000V fast recovery glass passivated rectifier diode in DO-15 package, featuring 1.3V forward voltage at 1.5A, 50A non-repetitive surge rating, and 150ns reverse recovery time-used in AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the PR1507G-T datasheet, PR1507G-T pinout, PR1507G-T application, or PR1507G-T equivalent, key selection criteria include peak reverse voltage (1000V), thermal resistance (65°C/W), low leakage (5μA @ 25°C), and DO-15 mechanical compatibility with legacy through-hole board layouts.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60Hz resistive or inductive loads, with derating required for capacitive loads. Its glass passivated junction ensures stable reverse characteristics and enhanced moisture resistance per J-STD-020C Level 1.
The 150ns reverse recovery time enables efficient switching in offline SMPS input stages, while the 65°C/W junction-to-ambient thermal resistance supports operation up to +150°C junction temperature when mounted on standard PCB copper areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse transients up to 1000V without breakdown in AC line applications. |
| IO @ 55°C | 1.5 A - Continuous average forward current rating at 55°C ambient, defining usable output capacity in convection-cooled designs. |
| VFM @ 1.5A | 1.3 V - Forward voltage drop determines conduction loss (1.95W max at full load) and thermal design margin. |
| IFSM | 50 A - Surge capability handles 8.3ms half-sine inrush events like capacitor charging or cold-start conditions. |
| trr | 150 ns - Fast recovery minimizes switching loss and EMI generation in high-frequency rectifier topologies. |
| IRM @ 25°C | 5.0 μA - Low leakage preserves efficiency in high-impedance bias networks and reduces standby power loss. |
| RθJA | 65 °C/W - Thermal resistance sets minimum PCB copper area needed to maintain Tj ≤ 150°C under full load. |
Pinout & Package
DO-15 molded plastic package with axial leads; cathode identified by band marking; tin-plated leads compliant with MIL-STD-202 Method 208 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input connection point | Accepts incoming alternating waveform; must withstand full peak inverse voltage during negative half-cycle. |
| Cathode | DC output connection point | Delivers rectified unidirectional current; polarity marking ensures correct orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Enables stable long-term reverse leakage performance and improved humidity resistance vs. epoxy-passivated alternatives. |
| Surge overload rating to 50A peak | Supports robust startup behavior in power supplies subject to high inrush currents without degradation. |
| Low reverse leakage (5μA @ 25°C) | Reduces standby power consumption and improves reliability in high-temperature environments. |
| RoHS-compliant lead finish | Meets EU Directive Annex exemptions for glass and high-temp solder, enabling compliance in regulated markets. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Front-end rectification in 85–265VAC input switch-mode power supplies for factory automation controllers. IC Role / Device Role / Timing Role: Discrete rectifier converting AC line to pulsating DC prior to bulk capacitor filtering and PWM conversion. Use Value: 1000V VRRM ensures margin against line surges; 150ns trr limits switching loss during high-frequency operation. | Use Scenario: Input stage of constant-current LED drivers used in street lighting and commercial signage. IC Role / Device Role / Timing Role: Unidirectional current path enabling capacitor-input filter design with minimal ripple and thermal stress. Use Value: 1.3V VFM balances conduction loss and thermal rise; DO-15 package allows manual rework and high-voltage creepage spacing. |
| UPS Battery Charger Circuits | Appliance Motor Control Rectifiers |
Use Scenario: AC-to-DC conversion in online UPS systems where battery charging circuitry interfaces directly with mains. IC Role / Device Role / Timing Role: Isolates AC source from DC bus during charging; handles bidirectional energy flow during transfer switching. Use Value: 50A IFSM accommodates transient overloads during battery equalization; low IRM prevents self-discharge during standby. | Use Scenario: Rectification in universal motor control modules for HVAC blowers and kitchen appliances. IC Role / Device Role / Timing Role: Provides DC link voltage for triac or MOSFET-based phase-angle control circuits. Use Value: DO-15 mechanical robustness withstands vibration; 65°C/W RθJA supports compact heatsink-less layout in enclosed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06U | TO-220AC package, 600V VRRM, 1.05V VFM @ 1A, 75ns trr | Limited to ≤600V AC lines; lower VF reduces conduction loss but requires heatsink mounting | Select when higher efficiency at lower voltage and surface-mount thermal management are prioritized. |
| ON Semiconductor MUR160 | DO-41 package, 600V VRRM, 1.25V VFM @ 1A, 75ns trr | Lower voltage rating and smaller DO-41 footprint; not suitable for 1000V-class surge immunity | Choose for space-constrained 230VAC designs where faster recovery and smaller size outweigh voltage margin needs. |
Compared with STTH1L06U and MUR160, PR1507G-T provides superior 1000V surge tolerance and DO-15 mechanical compatibility for through-hole industrial power supplies, trading off slightly slower recovery and higher VF for ruggedness and legacy board support.

FAQ
What is the maximum operating temperature for PR1507G-T?
The PR1507G-T has an operating junction temperature range of –65°C to +150°C. Its thermal resistance (RθJA = 65°C/W) means that at 1.5A continuous current and 1.3V forward drop, it dissipates ~1.95W-requiring adequate PCB copper area to keep Tj within limit under worst-case ambient conditions.
Is PR1507G-T RoHS compliant?
Yes, PR1507G-T features a lead-free finish and complies with RoHS Directive 2011/65/EU, including exemptions for glass and high-temperature solder per Annexes V and VII. Tin-plated leads meet MIL-STD-202 Method 208 solderability standards.
Can PR1507G-T replace PR1507GS-T?
No-PR1507G-T uses the DO-15 package (larger body, higher power dissipation), while PR1507GS-T uses DO-41 (smaller, lower thermal mass). They share identical electrical specs but differ mechanically; substitution requires board layout verification and thermal validation.
Why is PR1507G-T marked "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes Incorporated issued this notice due to newer alternatives offering faster recovery (e.g., <100ns), lower VF, or smaller packages. However, PR1507G-T remains fully qualified and supported for existing designs, especially where DO-15 mechanical fit, 1000V margin, and long-term supply stability are critical.
