Product details
Overview
PR3003-T from Diodes Incorporated is a 3.0A fast recovery rectifier diode in DO-201AD package, rated for 200V peak repetitive reverse voltage (VRRM), 1.2V forward voltage at 3.0A, and 150ns reverse recovery time - optimized for high-efficiency AC/DC front-end rectification in offline power supplies and industrial SMPS.
For engineers reviewing the PR3003-T datasheet, PR3003-T pinout, PR3003-T application, or PR3003-T equivalent, key selection criteria include VRRM derating margin, trr-dependent switching loss trade-offs, thermal resistance (RθJA = 15°C/W), and DO-201AD lead-form compatibility with automated tape-and-reel assembly.
Technical Context
This device uses a diffused junction structure to achieve fast recovery characteristics without soft-recovery tail current, enabling reduced EMI and improved efficiency in 50–100 kHz switch-mode topologies. Its 150 ns trr is measured under standardized conditions (IF = 0.5A, IR = 1.0A, Irr = 0.25A), ensuring consistent timing behavior across production lots.
The DO-201AD package supports 3.0A average forward current at TA = 90°C when leads are held at ambient within 9.5mm of the case, and its 15°C/W junction-to-ambient thermal resistance enables direct heatsink-less operation in moderate-power applications up to ~15W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum non-repetitive reverse voltage before breakdown; sets minimum input bridge rating for 115/230VAC systems. |
| IO @ TA=90°C | 3.0 A - Continuous DC output current capability with defined PCB copper area and lead thermal management. |
| VFM @ IF=3.0A | 1.2 V - Forward conduction loss contributing ~3.6W dissipation at full load; impacts thermal design and efficiency. |
| trr | 150 ns - Recovery delay limiting maximum practical switching frequency to ~300 kHz in hard-switched converters. |
| IFSM | 150 A - Single half-sine surge rating; withstands inrush currents during cold-start of 120VAC-fed power supplies. |
| RθJA | 15 °C/W - Junction-to-ambient thermal resistance; defines temperature rise per watt without heatsink or forced airflow. |
Pinout & Package
DO-201AD axial-leaded plastic package with cathode band marking; body length 7.2–9.5 mm, diameter 1.2–1.3 mm, lead diameter 0.5–0.6 mm, overall length 25.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction | Connected to AC input or transformer secondary; must handle full surge current and RMS heating. |
| Cathode (Lead 2, banded end) | Output terminal for forward conduction | Feeds bulk capacitor or downstream converter; polarity-sensitive for correct DC polarity establishment. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery (trr = 150 ns) | Reduces switching losses and EMI generation in 50–200 kHz flyback and forward converters. |
| 150 A IFSM surge rating | Supports reliable cold-start operation in universal-input AC/DC adapters without external inrush limiting. |
| Low IRM (5.0 µA @ 25°C) | Minimizes standby power loss in no-load or light-load conditions for energy-efficient designs. |
| RoHS-compliant tin-plated leads | Ensures solderability per MIL-STD-202 Method 208 and compatibility with lead-free reflow profiles. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Rectifying 115/230VAC mains input in enclosed 15–25W industrial power modules with natural convection cooling. IC Role / Device Role / Timing Role: Primary-side unidirectional current path; blocks reverse voltage during negative AC half-cycles while conducting forward current. Use Value: 200V VRRM provides 2× safety margin over 230VAC peak (325V), and 15°C/W RθJA allows operation without heatsink below 18W output. | Use Scenario: Input stage rectification in constant-current LED drivers powering streetlight or high-bay fixtures. IC Role / Device Role / Timing Role: Converts AC line to pulsating DC prior to buck or flyback regulation; operates continuously at 50/60Hz. Use Value: 3.0A IO rating supports >20W LED loads; low trr prevents excessive ringing when paired with EMI filter inductors. |
| UPS Battery Charger Front-End | Motor Drive Auxiliary Supply |
Use Scenario: Charging circuit rectification in line-interactive UPS units where battery backup requires stable DC bus generation. IC Role / Device Role / Timing Role: Half-wave or full-bridge rectifier delivering DC to charging controller IC and battery management circuitry. Use Value: 150A IFSM withstands repeated battery equalization surges; 1.2V VFM limits heat buildup during extended float-charge operation. | Use Scenario: Isolated auxiliary supply rectification in 3-phase inverter gate driver boards requiring clean +15V/-15V rails. IC Role / Device Role / Timing Role: Secondary-side rectifier in small flyback transformer supplying isolated bias power to IGBT/SiC gate drivers. Use Value: Fast trr ensures minimal cross-conduction risk during high dv/dt switching events on primary side. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L02 | VRRM = 200V, trr = 100 ns, VFM = 1.15V @ 3A, DO-201AD | Lower trr reduces switching loss but higher cost; tighter VFM tolerance improves thermal predictability. | Select when operating above 200 kHz or requiring lower EMI in compact enclosures. |
| ON Semi MUR320 | VRRM = 200V, trr = 35 ns, VFM = 1.3V @ 3A, DO-201AD | Ultra-fast trr enables >500 kHz operation but increases reverse recovery noise and requires snubber optimization. | Select for high-frequency resonant converters where trr dominates total loss budget. |
Compared with STTH3L02 and MUR320, PR3003-T offers balanced trr/VFM trade-off and proven reliability in cost-sensitive 50–150 kHz industrial power supplies, making it optimal for mainstream AC/DC conversion where thermal margin and manufacturability outweigh ultra-fast switching needs.

FAQ
What is the maximum allowable case temperature for continuous operation of PR3003-T?
The device is rated for continuous operation with case temperature up to +150°C, but average forward current must be derated linearly from 3.0A at TA = 90°C to zero at TA = 150°C per Figure 1. Sustained operation above 125°C requires thermal modeling to confirm junction temperature remains within -65°C to +150°C range.
Can PR3003-T replace PR3002-T in a 100V-rated design?
No - PR3003-T has 200V VRRM versus PR3002-T's 100V rating. Substituting it into a 100V design introduces unnecessary voltage overhead and may affect layout parasitics or snubber sizing. However, it is electrically safe if board-level clearance and creepage distances support 200V isolation.
Is PR3003-T suitable for use in a full-bridge rectifier configuration?
Yes - each PR3003-T diode handles one quadrant of the full-bridge. Its 200V VRRM and 150A IFSM make it appropriate for 115/230VAC full-bridge inputs. Ensure symmetrical PCB layout and thermal coupling to avoid current imbalance; parallel devices require individual thermal vias and matching trace lengths.
Does PR3003-T meet JEDEC moisture sensitivity level requirements?
Yes - PR3003-T is rated Moisture Sensitivity Level 1 per J-STD-020C, meaning it can be stored indefinitely at ≤30°C/85% RH and subjected to standard surface-mount reflow without baking, provided packaging remains unopened and humidity indicator cards show no exposure.
