Product details
Overview
PR3001G-T from Diodes Incorporated is a 3.0A, 50V fast recovery glass passivated rectifier diode in DO-201AD package, designed for high-efficiency AC/DC conversion in offline power supplies and switching adapters. It delivers 1.3V forward voltage at 3.0A, 125A non-repetitive surge capability, and 150ns reverse recovery time, enabling compact, thermally robust designs in industrial and consumer SMPS.
For engineers reviewing the PR3001G-T datasheet, PR3001G-T pinout, PR3001G-T application, or PR3001G-T equivalent, key selection criteria include peak repetitive reverse voltage (50V), average forward current rating (3.0A @ 55°C), thermal resistance (32°C/W), reverse recovery time (150ns), and DO-201AD mechanical compatibility with standard through-hole layouts.
Technical Context
This device operates as a single-phase, half-wave rectifier under resistive or inductive loads at 60Hz, with derating required for capacitive loads. Its glass passivated junction ensures stable reverse leakage (<5.0μA at 25°C) and reliable operation across –65°C to +150°C ambient and junction temperatures.
The fast recovery characteristic (trr = 150ns) is measured under defined conditions (IF = 0.5A, IR = 1A, Irr = 0.25A), supporting higher switching frequencies than standard recovery diodes while maintaining low forward conduction loss (VFM = 1.3V @ 3.0A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum peak repetitive reverse voltage; defines safe blocking capability in AC line rectification. |
| IO @ TA=55°C | 3.0 A - Continuous average forward current; requires lead temperature control at 9.5mm from case. |
| VFM @ IF=3.0A | 1.3 V - Forward voltage drop; determines conduction loss and thermal dissipation in power stage. |
| IFSM | 125 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush current handling in input stages. |
| trr | 150 ns - Reverse recovery time; enables efficient operation up to ~100kHz switching in flyback and forward converters. |
| RθJA | 32 °C/W - Junction-to-ambient thermal resistance; informs heatsinking requirements for sustained 3.0A operation. |
| IRM @ 25°C | 5.0 μA - Peak reverse leakage; critical for low-power standby and high-impedance bias networks. |
Pinout & Package
Package: DO-201AD molded plastic case (UL 94V-0), cathode-banded polarity, tin-plated leads, 1.12g weight. Leads are solderable per MIL-STD-202, Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to AC source or transformer secondary; must withstand surge and thermal stress. |
| Cathode | Forward current exit / DC output node | Connects to bulk capacitor or downstream regulator; polarity marking (band) prevents misorientation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enhances humidity resistance and long-term reliability in unsealed industrial environments. |
| Fast recovery (150ns) | Reduces switching losses and EMI generation compared to general-purpose rectifiers in 50–100kHz SMPS. |
| 125A surge rating | Withstands cold-start inrush without degradation, eliminating need for external NTC thermistors in many adapters. |
| Low IRM (5.0μA @ 25°C) | Minimizes standby power loss in energy-efficient designs complying with Level VI or ErP standards. |
Applications
| AC-DC Adapter Input Stage | Industrial SMPS Primary Rectification |
|---|---|
Use Scenario: 5–24W wall adapter converting 90–264VAC to 5–12VDC using flyback topology. IC Role / Device Role / Timing Role: Primary-side bridge or half-wave rectifier converting AC line to pulsating DC before bulk capacitor. Use Value: 1.3V VFM and 150ns trr reduce conduction and switching losses, improving efficiency by ~1.2% over standard 1N4007-based designs. | Use Scenario: 30–60W open-frame industrial power supply operating in harsh ambient (–25°C to +70°C). IC Role / Device Role / Timing Role: Input rectifier in dual-switch forward converter with active clamp snubber. Use Value: 125A IFSM and –65°C to +150°C Tj range ensure robustness during repeated cold starts and extended thermal cycling. |
| LED Driver Bulk Rectification | Automotive Aftermarket Power Module |
Use Scenario: Constant-current LED driver for street lighting, accepting universal AC input. IC Role / Device Role / Timing Role: Front-end rectifier feeding PFC controller and DC/DC stage. Use Value: Low 5.0μA IRM at 25°C and stable leakage up to 125°C maintain low no-load consumption and prevent false triggering of protection circuits. | Use Scenario: 12V DC-DC module powering infotainment systems from vehicle battery (13.5–16V nominal, transients to 40V). IC Role / Device Role / Timing Role: Reverse-polarity protection and input surge clamping rectifier in hybrid discrete front-end. Use Value: DO-201AD mechanical robustness and 32°C/W RθJA support reliable operation without heatsink in confined under-dash 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 |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3.0A IO, TO-220AC package, trr = 50ns | Higher voltage rating; requires heatsink due to higher RθJA (~40°C/W) | Preferred for 230VAC+ PFC front-ends where 50V rating is insufficient. |
| ON Semi MUR305 | 50V VRRM, 3.0A IO, DO-201AD, trr = 75ns, VFM = 1.25V | Faster recovery and slightly lower VFM; RoHS-compliant but not lead-free finish | Better efficiency in high-frequency adapters; verify Pb-free compliance for medical/industrial end-equipment. |
Compared with STTH3L06S and MUR305, PR3001G-T offers optimal balance of cost, DO-201AD footprint compatibility, and sufficient 50V rating for low-voltage universal-input adapters-making it suitable where space, thermal budget, and regulatory compliance (lead-free/RoHS) are jointly constrained.

FAQ
Is PR3001G-T suitable for use in new designs?
No-Diodes Incorporated explicitly marks PR3001G-T as "NOT RECOMMENDED FOR NEW DESIGN" in its official datasheet (DS27003 Rev. 7). It remains available for legacy production and repair, but newer alternatives like the MUR305 or SB350 are recommended for new projects due to improved trr, VFM, and lifetime support.
What is the maximum allowable PCB pad temperature during reflow soldering?
PR3001G-T uses tin-plated leads compliant with MIL-STD-202, Method 208, and is rated for moisture sensitivity Level 1 (J-STD-020C). Standard SnPb or lead-free reflow profiles apply; peak temperature must not exceed 260°C for ≤10 seconds, with preheat ramp ≤3°C/s to avoid thermal shock to the glass-passivated junction.
Can PR3001G-T replace a 1N4001 in a linear power supply?
Yes-PR3001G-T matches or exceeds 1N4001's 50V VRRM and 1A IO rating, but its 3.0A IO and 125A IFSM provide significant margin. However, its faster trr (150ns vs. ~30μs) may increase EMI in unfiltered linear supplies; ferrite beads or RC snubbers may be needed if noise is observed.
Does PR3001G-T require a heatsink in continuous 3.0A operation?
No heatsink is required if ambient temperature stays ≤55°C and leads are maintained at ambient temperature at ≥9.5mm from the case, per datasheet Note 1. At higher ambient or with restricted airflow, thermal simulation using RθJA = 32°C/W and Pd = IO × VFM ≈ 3.9W confirms junction temperature rise of ~125°C-exceeding 150°C max unless heatsinking or derating is applied.
