Product details
Overview
PR3002-T from Diodes Incorporated is a 3.0A fast recovery rectifier diode in DO-201AD package, rated for 100V peak repetitive reverse voltage (VRRM), 1.2V forward voltage at 3.0A, and 150ns reverse recovery time - designed for high-efficiency AC/DC front-end rectification in offline power supplies and industrial SMPS.
For engineers reviewing the PR3002-T datasheet, PR3002-T pinout, PR3002-T application, or PR3002-T equivalent, key selection criteria include VRRM derating margin, trr-dependent switching loss in 50–100kHz flyback converters, thermal resistance (15°C/W) under lead-length-constrained PCB layouts, and RoHS-compliant tin-plated leads for lead-free reflow compatibility.
Technical Context
This device employs a diffused PN junction optimized for fast recovery (trr = 150ns) with low stored charge, enabling reduced switching losses in high-frequency rectification circuits. Its 150A non-repetitive surge rating supports inrush current handling in unregulated input stages.
Thermal performance is defined under standardized lead-length conditions (9.5mm from case), and reverse leakage remains ≤5.0mA at 25°C and ≤100mA at 100°C - critical for maintaining efficiency across wide ambient temperature ranges (-65°C to +150°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum allowable repetitive reverse voltage before breakdown; sets minimum insulation margin for 85–265VAC input designs. |
| IO @ TA=90°C | 3.0 A - Continuous average forward current with leads held at ambient at 9.5mm distance; defines usable DC output capability in thermally constrained layouts. |
| VFM @ IF=3.0A | 1.2 V - Forward conduction loss at rated current; contributes ~3.6W conduction loss per diode in full-wave bridge configurations. |
| trr | 150 ns - Reverse recovery time measured at IF=0.5A, IR=1.0A, Irr=0.25A; directly impacts EMI and switching loss in 50–100kHz hard-switched topologies. |
| RθJA | 15 °C/W - Junction-to-ambient thermal resistance under specified mounting condition; enables estimation of junction temperature rise in natural-convection environments. |
| IRM @ 25°C | 5.0 mA - Peak reverse leakage at rated DC blocking voltage and room temperature; affects standby power in no-load conditions. |
Pinout & Package
DO-201AD 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 | Forward current entry point | Connected to AC input or transformer secondary; must withstand surge currents up to 150A (8.3ms half-sine). |
| Cathode | Forward current exit / reverse voltage reference | Marked with band; ties to output capacitor or ground return; reverse voltage applied here during off-state. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery (trr) | 150 ns - Enables efficient operation in 50–100 kHz switch-mode power supplies without excessive switching loss or EMI. |
| Surge robustness | 150 A IFSM (8.3ms) - Supports repeated cold-start surges in universal-input AC/DC adapters and industrial power modules. |
| Low thermal resistance | 15 °C/W RθJA - Allows reliable 3.0A operation at 90°C ambient when mounted per JEDEC standard lead length. |
| RoHS-compliant finish | Tin-plated leads - Ensures compatibility with lead-free reflow profiles (peak ≤260°C) and long-term solder joint reliability. |
Applications
| AC/DC Adapter Front-End | Industrial SMPS Input Stage |
|---|---|
Use Scenario: Rectifying 50/60Hz AC line input in compact wall-wart adapters delivering 5–24V DC. IC Role / Device Role / Timing Role: Fast recovery rectifier in single-phase half-wave or full-wave bridge configuration.

Use Value: Low 5.0mA IRM at 25°C reduces no-load power consumption below 30mW, supporting Energy Star Tier 2 compliance. |
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 | VRRM = 600V, trr = 75ns, IO = 3.0A, SOD-123FL package | Higher voltage rating but lower surge rating (80A); surface-mount only | Select when higher VRRM margin or faster recovery is required and board space permits SMT layout. |
| ON Semi MUR3020CT | VRRM = 200V, trr = 75ns, IO = 3.0A, TO-220AB package | Dual-diode configuration; requires heatsinking above 1.5A continuous | Choose for dual common-cathode rectification where thermal management allows TO-220 mounting. |
Compared with STTH3L06S and MUR3020CT, PR3002-T offers optimal balance of 100V rating, 150ns recovery, axial DO-201AD through-hole compatibility, and 150A surge tolerance - making it preferred for cost-sensitive, thermally constrained, and high-inrush legacy power supply designs.

FAQ
What is the maximum allowable ambient temperature for continuous 3.0A operation?
PR3002-T sustains 3.0A average forward current at TA = 90°C, provided leads are maintained at ambient temperature at a distance of 9.5mm from the case. At higher ambient temperatures, derating is required per Figure 1 - e.g., 2.2A at 110°C ambient.
Can PR3002-T replace PR3001-T in a 50V design?
Yes - PR3002-T (100V VRRM) exceeds the 50V requirement of PR3001-T and maintains identical package, thermal, and surge characteristics. Its higher voltage rating provides additional safety margin against transients without altering layout or thermal design.
Is PR3002-T suitable for high-frequency resonant LLC rectification?
No - its 150ns trr is optimized for 50–100kHz hard-switched topologies, not MHz-range resonant rectification. For LLC secondaries, Schottky or SiC diodes with trr < 20ns are recommended to minimize body diode conduction loss and ringing.
Does PR3002-T require heatsinking in typical adapter applications?
Not typically - with RθJA = 15°C/W and 3.0A at 90°C ambient, junction temperature stays below 150°C under standard DO-201AD mounting (9.5mm lead length). Heatsinking becomes necessary only if ambient exceeds 90°C or if sustained current exceeds 2.5A in enclosed enclosures.
