Product details
Overview
PR1504G-T from Diodes Incorporated is a 1.5A fast recovery glass passivated rectifier diode in DO-15 package, rated for 400V peak repetitive reverse voltage, 1.3V forward voltage at 1.5A, and 150ns reverse recovery time, used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR1504G-T datasheet, PR1504G-T pinout, PR1504G-T application, or PR1504G-T equivalent, key selection criteria include VRRM=400V, IO=1.5A@55°C, trr=150ns, low IRM=5.0μA@25°C, and DO-15 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching power conversion. Its glass passivated die construction ensures stable performance under thermal cycling, while the 150ns reverse recovery time enables operation in 50–100kHz SMPS front-end stages without excessive switching loss.
The DO-15 package provides robust thermal resistance (RθJA = 65°C/W) and supports 50A non-repetitive surge current handling. Polarity is marked by a cathode band; terminals are tin-plated for MIL-STD-202-compliant solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage before breakdown; sets safe operating limit in 230VAC input bridge configurations. |
| IO @ 55°C | 1.5 A - Continuous average forward current rating at 55°C ambient; defines usable output capacity in thermally constrained enclosures. |
| VFM @ 1.5A | 1.3 V - Forward voltage drop at rated current; determines conduction loss (1.95W max) and thermal load in linear rectifier designs. |
| trr | 150 ns - Reverse recovery time; enables efficient operation up to ~100kHz without significant commutation loss or EMI generation. |
| IRM @ 25°C | 5.0 μA - Peak reverse leakage at rated DC blocking voltage; ensures minimal standby power loss in high-impedance hold-up circuits. |
| RθJA | 65 °C/W - Junction-to-ambient thermal resistance; allows estimation of junction temperature rise (ΔTj ≈ 127°C at full load, no heatsink). |
Pinout & Package
PR1504G-T uses the axial-lead DO-15 molded plastic package (UL 94V-0), with cathode identified by a band near one lead end. Leads are tin-plated and solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must withstand 50A surge transients during cold-start. |
| Cathode | Forward current exit point | Connected to bulk capacitor positive rail; polarity marking ensures correct orientation in bridge or half-wave layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Eliminates moisture-induced degradation and improves long-term reliability in humid industrial environments. |
| Fast recovery (150ns) | Reduces reverse recovery charge (Qrr) to <15nC, minimizing switching loss and snubber requirements in 60–100kHz converters. |
| 50A IFSM rating | Withstands inrush currents from large input capacitors without failure, supporting robust startup behavior in offline SMPS. |
| RoHS-compliant finish | Tin-plated leads meet EU Directive Annex exemptions for glass and high-temp solder, enabling compliance in export-bound equipment. |
Applications
| AC/DC Power Adapter Input Stage | Industrial LED Driver Rectification |
|---|---|
Use Scenario: Single-phase 230VAC input rectification feeding a 30W flyback converter with 47μF/400V bulk capacitor. IC Role / Device Role / Timing Role: Primary-side unidirectional current valve converting AC line to pulsating DC; timing role defined by 50Hz/60Hz line frequency envelope. Use Value: 400V VRRM safely accommodates 230VAC + 30% tolerance and transient spikes; 1.3V VFM limits conduction loss to ≤1.95W at full load. | Use Scenario: Half-wave rectification in constant-current LED driver for street lighting, operating at 100kHz PWM dimming. IC Role / Device Role / Timing Role: Line-frequency rectifier preceding high-frequency buck controller; timing role independent of PWM but critical for ripple amplitude fed to filter stage. Use Value: 150ns trr prevents tail current overlap with switching transitions, reducing audible noise and EMI in dimmed operation. |
| UPS Battery Charger Input | Appliance Motor Control Bridge |
Use Scenario: Dual-diode configuration in 120VAC battery charger for telecom backup systems with active PFC pre-regulator. IC Role / Device Role / Timing Role: Secondary rectifier in isolated DC/DC stage delivering 28V@3A to sealed lead-acid battery; operates at 100kHz switching frequency. Use Value: Low 5.0μA IRM minimizes self-discharge during standby, extending battery hold-up time between grid outages. | Use Scenario: Half-wave rectifier in universal motor speed control circuit for power tools, interfacing triac-based phase-angle dimming. IC Role / Device Role / Timing Role: Unidirectional clamp protecting triac gate drive from reverse voltage; timing role synchronized to zero-crossing detection. Use Value: 50A IFSM rating absorbs energy from inductive kickback during abrupt motor shutdown, preventing gate oxide damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L04S | DO-204AL (DO-41) package; 400V VRRM, 1.0A IO, 50ns trr, 1.15V VFM | Lower current rating and faster recovery; suited for lower-power, higher-frequency designs | Select when board space permits smaller DO-41 and efficiency at >200kHz is prioritized over surge robustness |
| ON Semiconductor MUR150 | DO-15 package; 50V VRRM, 1.5A IO, 75ns trr, 0.95V VFM | Lower voltage rating; intended for low-voltage DC/DC or automotive auxiliary supplies | Choose only for sub-100V applications where ultra-low VFM and fast trr outweigh voltage margin needs |
Compared with STTH1L04S and MUR150, PR1504G-T offers superior surge immunity (50A vs. 30A/25A) and higher voltage margin for global AC mains, making it preferred for industrial 230VAC inputs despite slower recovery than STTH1L04S.

FAQ
Is PR1504G-T suitable for use in new designs?
No - Diodes Incorporated explicitly marks PR1501G/S through PR1507G/S as "NOT RECOMMENDED FOR NEW DESIGN" in the official datasheet. It remains available for legacy support and existing production, but designers should evaluate modern alternatives like the DFLS160 or SB140 for new projects requiring improved efficiency or RoHS-2 compliance.
What is the difference between PR1504G-T and PR1504GS-T?
PR1504G-T uses the DO-15 package (larger body, 5.5–7.62mm length), while PR1504GS-T uses the DO-41 package (smaller body, 4.06–5.21mm length). Both share identical electrical specs (400V VRRM, 1.5A IO, 150ns trr), but DO-15 offers better thermal dissipation (RθJA = 65°C/W vs. ~75°C/W for DO-41) and higher mechanical robustness for automated insertion.
Can PR1504G-T be used in surface-mount designs?
No - PR1504G-T is an axial-lead through-hole device in DO-15 package and is not compatible with SMT assembly. It requires wave soldering or hand-soldering into plated-through holes. For SMT equivalents, consider Diodes Inc.'s B140WS (SOD-123W, 40V) or evaluate DO-214AA (SMA) packages like SR140, though voltage/current ratings differ.
What derating applies to PR1504G-T at elevated ambient temperatures?
Per Figure 1 in the datasheet, PR1504G-T's average forward current must be linearly derated above 55°C ambient: at 100°C ambient, IO drops to ~0.9A; at 125°C, it falls to ~0.5A. Derating assumes leads are held at ambient temperature at 9.5mm from case - forced-air cooling or heatsinking significantly improves usable current.
