Product details
Overview
PR1502G-T from Diodes Incorporated is a 1.5A fast recovery glass passivated rectifier diode in DO-15 package, rated for 100V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 1.5A (VFM), and 50A non-repetitive surge current (IFSM); used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR1502G-T datasheet, PR1502G-T pinout, PR1502G-T application, or PR1502G-T equivalent, key selection criteria include VRRM derating margin, thermal resistance (RθJA = 65°C/W), reverse recovery time (trr = 250 ns), and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device operates as a single-phase, half-wave rectifier under 60Hz resistive or inductive loads, with forward current derated above 55°C ambient per Figure 1. It employs glass passivated die construction to ensure stable reverse leakage (IRM = 5.0 μA @ 25°C) and robust surge capability (50A IFSM).
Reverse recovery time is measured under defined conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A), and total capacitance (CT = 25 pF) is specified at 1.0 MHz and 4.0V reverse bias - critical for high-frequency switching noise control in offline SMPS front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets minimum insulation margin for 120VAC input designs. |
| IO @ TA=55°C | 1.5 A - Continuous average forward current rating at 55°C ambient; requires heatsinking or airflow above this temperature. |
| VFM @ IF=1.5A | 1.3 V - Forward voltage drop determining conduction loss (1.95W max at full load) and thermal rise in linear rectifier stages. |
| IFSM (8.3ms) | 50 A - Surge withstand capability during cold-start inrush; supports compliance with IEC 61000-4-5 line transient immunity. |
| trr | 250 ns - Reverse recovery time affecting switching losses and EMI generation in high-frequency rectifier applications. |
| RθJA | 65 °C/W - Junction-to-ambient thermal resistance; defines required PCB copper area or heatsink for safe operation at full load. |
| IRM @ 25°C | 5.0 μA - Low reverse leakage ensures minimal standby power loss in always-on auxiliary supplies. |
Pinout & Package
DO-15 molded plastic package (UL 94V-0), axial leaded, cathode indicated by band. Leads are tin-plated, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input for positive half-cycle conduction | Connected to AC source or transformer secondary; must handle full surge current and RMS voltage stress. |
| Cathode | Output for rectified DC | Feeds bulk capacitor or downstream regulator; polarity marking ensures correct orientation on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances humidity resistance and long-term reliability in humid industrial environments without conformal coating. |
| Fast recovery (250 ns) | Reduces switching loss and ringing in 50–100 kHz SMPS input stages compared to standard recovery rectifiers. |
| 50A surge rating | Withstands repeated cold-start surges in unregulated AC/DC adapters without degradation or failure. |
| RoHS-compliant tin finish | Enables lead-free reflow or hand-soldering while maintaining wetting performance and intermetallic bond integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4002GP-E3/54 (Vishay) | Same DO-15 package, but 100V VRRM and 1A IO rating; slower trr (~2 μs) and higher VFM (1.5V). | Lower current handling limits use to sub-1A auxiliary rails; unsuitable for 1.5A continuous loads. | Select only when cost sensitivity outweighs efficiency and thermal margin requirements. |
| ES1B (ON Semiconductor) | SMD SMB package, 100V VRRM, 1A IO, 35 ns trr, 1.7V VFM; not pin-compatible. | Requires PCB redesign; better for high-frequency, space-constrained designs but lacks surge robustness. | Choose for automated assembly and EMI-sensitive applications where layout flexibility permits SMD adoption. |
Compared with 1N4002GP-E3/54 and ES1B, PR1502G-T uniquely balances 1.5A current capacity, 250 ns recovery, and DO-15 through-hole manufacturability - making it optimal for cost-sensitive, thermally constrained, and serviceable industrial rectifier designs.

FAQ
Is PR1502G-T suitable for use in 230VAC input applications?
No. With a 100V peak repetitive reverse voltage (VRRM), PR1502G-T is rated only for 120VAC nominal inputs. For 230VAC systems, the minimum required VRRM is typically ≥600V (e.g., PR1505G-T). Using PR1502G-T on 230VAC risks catastrophic reverse breakdown during voltage peaks.
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is +150°C, but sustained operation above 125°C requires significant thermal management. At 55°C ambient, the device supports 1.5A IO; derating follows the curve in Figure 1 - e.g., at 100°C ambient, IO drops to ~0.75A due to RθJA = 65°C/W and self-heating.
Does PR1502G-T have a qualified automotive grade variant?
No. PR1502G-T is not AEC-Q101 qualified and is explicitly marked "NOT RECOMMENDED FOR NEW DESIGN" in its datasheet. Diodes does not offer an automotive-grade version of this part; alternative AEC-Q101 rectifiers like the SB1100 or DFLS1100 should be considered for automotive applications.
Can PR1502G-T be substituted with a Schottky diode for lower VFM?
Not directly. Schottky diodes with comparable VRRM (e.g., 100V) typically exhibit higher reverse leakage (≥100 μA at 25°C) and cannot withstand 50A surges. PR1502G-T's 5.0 μA IRM and 50A IFSM make it more robust for mains-connected applications where leakage and surge immunity are critical.
