Product details
Overview
PR1503G-T from Diodes Incorporated is a 1.5A fast recovery glass passivated rectifier diode in DO-15 package, rated for 200V peak repetitive reverse voltage, 1.3V forward voltage at 1.5A, and 150ns reverse recovery time, used in AC/DC input stage rectification for offline power supplies and auxiliary power rails.
For engineers reviewing the PR1503G-T datasheet, PR1503G-T pinout, PR1503G-T application, or PR1503G-T equivalent, key selection criteria include its 200V VRRM rating, 50A non-repetitive surge capability, low 5.0μA reverse leakage at 25°C, thermal resistance of 65°C/W, and DO-15 through-hole mechanical compatibility with legacy 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 (−20% current). Its glass passivated die construction ensures stable junction performance across −65°C to +150°C operating range.
The 150ns reverse recovery time enables efficient switching in high-frequency flyback and forward converter auxiliary windings, while its 25pF typical junction capacitance minimizes high-frequency noise coupling in EMI-sensitive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum peak reverse voltage sustainable without breakdown; sets safe operating margin for 170VAC-derived DC bus applications. |
| IO @ 55°C | 1.5 A - Continuous average forward current at 55°C ambient; defines usable output capacity in convection-cooled power supplies. |
| VFM @ 1.5A | 1.3 V - Forward voltage drop at rated current; directly determines conduction loss (1.95W max) and thermal design requirements. |
| IFSM | 50 A - Non-repetitive surge rating for 8.3ms half-sine; supports cold-start inrush and transient overload handling. |
| trr | 150 ns - Reverse recovery time measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables operation up to ~500kHz switching frequencies. |
| RθJA | 65 °C/W - Junction-to-ambient thermal resistance; used to calculate junction temperature rise above ambient under steady-state load. |
| IRM @ 25°C | 5.0 μA - Peak reverse leakage at rated DC blocking voltage; critical for low-power standby circuits and high-impedance bias networks. |
Pinout & Package
DO-15 molded plastic package with axial leads, cathode band marking, tin-plated solderable terminals, UL 94V-0 flammability rating, and moisture sensitivity level 1. Weight: 0.40 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must withstand full surge current and reverse voltage during off-state. |
| Cathode | Forward current exit / DC output node | Feeds bulk capacitor or downstream regulator; polarity marking (band) prevents reverse installation in PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates silicon surface contamination and enhances long-term reliability under humidity and thermal cycling stress. |
| Fast recovery (150ns) | Reduces switching losses and EMI generation compared to standard recovery rectifiers in SMPS auxiliary supplies. |
| 50A surge rating | Supports repeated cold-start events without degradation-critical for industrial equipment with frequent power cycling. |
| Low 5.0μA reverse leakage | Minimizes standby power loss in energy-efficient designs compliant with EU CoC v5 or DOE Level VI standards. |
| DO-15 mechanical compatibility | Enables drop-in replacement for legacy 1N400x and 1N540x series in existing through-hole power supply designs. |
Applications
| AC/DC Adapter Input Stage | Industrial PLC Power Supply |
|---|---|

Use Value: DO-15 package allows robust mechanical mounting; 65°C/W RθJA enables natural convection cooling without heatsink. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4934GP-E3/54 | Same DO-15 package, 200V VRRM, but 1.25V VFM and 200ns trr; higher 10μA IRM at 25°C. | Suitable for cost-sensitive consumer adapters where slightly higher leakage is acceptable. | Select when lower forward drop is prioritized over ultra-low leakage or fastest recovery. |
| ES1D-E3/54 | DO-214AC (SMA) surface-mount package, 200V VRRM, 1.7V VFM, 35ns trr; 500μA IRM at 25°C. | Used in space-constrained, automated assembly environments requiring SMT footprint. | Choose only if board redesign supports SMA package and higher leakage can be tolerated. |
Compared with 1N4934GP-E3/54, PR1503G-T offers tighter reverse leakage and faster recovery; versus ES1D-E3/54, it trades superior thermal performance and lower leakage for through-hole assembly compatibility and higher surge tolerance.

FAQ
Is PR1503G-T RoHS compliant?
Yes, PR1503G-T features 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 requirements.
What is the maximum operating temperature for PR1503G-T?
The PR1503G-T has an operating junction temperature range of −65°C to +150°C. Its storage temperature matches this range. Derating curves in the datasheet define safe current limits above 55°C ambient, based on thermal resistance of 65°C/W and lead length constraints.
Can PR1503G-T replace 1N4004 in existing designs?
Yes-PR1503G-T is a direct functional upgrade: both are DO-15, 200V-rated rectifiers, but PR1503G-T offers faster recovery (150ns vs. 2μs), lower forward voltage (1.3V vs. 1.1V at 1A), and higher surge rating (50A vs. 30A), making it suitable for higher-frequency or higher-reliability applications.
Why is PR1503G-T marked "Not Recommended for New Design"?
Diodes Incorporated issued this notice due to strategic portfolio rationalization-not performance or reliability concerns. The device remains fully qualified, in active production, and supported with full datasheet, packaging, and quality documentation for legacy program continuity and repair use.
