Product details
Overview
PR3005-T from Diodes Incorporated is a 3.0A fast recovery rectifier diode in DO-201AD package, rated for 600V peak repetitive reverse voltage (VRRM), 1.2V forward voltage at 3.0A, and 150ns reverse recovery time (trr). It features low reverse leakage (5.0mA @ 25°C), surge capability up to 150A peak, and RoHS-compliant tin-plated leads. Used in AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the PR3005-T datasheet, PR3005-T pinout, PR3005-T application, or PR3005-T equivalent, key selection criteria include VRRM rating, IF(AV) derating at elevated ambient temperature, trr for switching loss minimization, thermal resistance (RθJA = 15°C/W), and DO-201AD mechanical compatibility with high-volume through-hole assembly.
Technical Context
This device is a planar diffused-junction silicon rectifier optimized for high-efficiency, medium-power AC-to-DC conversion. Its 600V blocking capability supports universal input (85–265VAC) offline SMPS designs, while the 150ns trr enables operation up to ~100kHz without excessive switching losses.
The DO-201AD package provides robust thermal performance (RθJA = 15°C/W) under natural convection when leads are held at ambient within 9.5mm of the case. Reverse leakage remains ≤100mA at 100°C, supporting reliable operation in thermally demanding environments such as enclosed industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse voltage before breakdown; sets minimum insulation margin for 400VDC bus applications. |
| IF(AV) | 3.0 A @ TA = 90°C - Average forward current rating under defined thermal conditions; requires PCB copper area or heatsinking above 70°C ambient. |
| VFM | 1.2 V @ IF = 3.0A - Forward conduction loss directly impacts efficiency; contributes ~3.6W conduction loss at full load. |
| trr | 150 ns - Reverse recovery time determines turn-off switching loss and EMI generation in hard-switched topologies. |
| IFSM | 150 A (8.3ms half-sine) - Surge rating defines immunity to line transients and inrush currents during cold start. |
| RθJA | 15 °C/W - Junction-to-ambient thermal resistance under standard mounting; used to calculate max junction temperature rise. |
| IRM | 5.0 mA @ 25°C - Low reverse leakage preserves hold-up capacitor charge and reduces standby power loss. |
Pinout & Package
DO-201AD package: axial-leaded, molded plastic case (UL 94V-0), cathode band marking, tin-plated leads solderable per MIL-STD-202 Method 208. Weight: 1.12 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to AC input or transformer secondary; must withstand surge current and reverse voltage stress. |
| Cathode (Lead 2, banded end) | Forward current exit / DC output node | Connects to bulk capacitor positive rail; polarity critical for correct rectification and EMI filter orientation. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery (trr = 150 ns) | Reduces switching loss and diode-induced ringing in flyback and forward converters operating >50kHz. |
| 150A non-repetitive surge rating | Withstands 8.3ms line surges and transformer inrush without degradation, eliminating need for external NTC or fusing in many cases. |
| Low IRM (5.0mA @ 25°C) | Minimizes standby power loss and improves no-load regulation in energy-efficient power adapters. |
| DO-201AD mechanical standardization | Enables drop-in replacement across legacy 3A rectifier families and supports automated through-hole insertion. |
Applications
| Industrial AC/DC Power Supply | LED Driver Input Stage |
|---|---|
Use Scenario: Single-phase, 60Hz, 230VAC input rectification feeding a PFC boost stage. IC Role / Device Role / Timing Role: Main input rectifier diode in bridge configuration (as one leg) or discrete half-wave configuration. Use Value: 600V VRRM ensures margin against 380VDC peak line transients; 150ns trr limits switching loss during PFC controller dead-time. | Use Scenario: Off-line LED driver with passive X-capacitor EMI filtering and bulk capacitance. IC Role / Device Role / Timing Role: Primary-side rectifier converting AC line to high-voltage DC bus prior to buck/buck-boost regulation. Use Value: Low IRM preserves capacitor charge between half-cycles, improving dimming stability and reducing audible noise in TRIAC-dimmable drivers. |
| UPS Battery Charger Input | Motor Drive Auxiliary Power Supply |
Use Scenario: Dual-input rectifier accepting either utility AC or generator AC for battery charging circuitry. IC Role / Device Role / Timing Role: Input rectifier in dual-source selector circuit with relay or MOSFET OR-ing. Use Value: 150A IFSM handles generator startup surges; DO-201AD lead spacing accommodates creepage requirements for reinforced isolation. | Use Scenario: Auxiliary 24V DC supply derived from main 3-phase AC bus via step-down transformer and rectification. IC Role / Device Role / Timing Role: Secondary-side rectifier in isolated auxiliary SMPS fed by 24VAC winding. Use Value: RθJA = 15°C/W allows operation at 85°C ambient without forced air; 1.2V VFM maintains regulation accuracy under variable load. |
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, IF(AV) = 3.0A, trr = 110ns, TO-220AC package | Higher thermal mass but requires heatsink; lower trr reduces switching loss further | Select when board space permits TO-220 and higher efficiency at >100kHz is required |
| ON Semi MUR3060CT | VRRM = 600V, IF(AV) = 3.0A per diode, trr = 60ns, TO-220AB dual common-cathode | Dual-diode configuration enables full-wave center-tap or synchronous rectification; faster trr | Choose for full-wave rectification or where dual-diode layout simplifies transformer secondary routing |
Compared with STTH3L06S and MUR3060CT, PR3005-T offers lowest cost and smallest footprint in DO-201AD, making it optimal for cost-sensitive, space-constrained single-phase rectifiers where 150ns trr meets system efficiency targets.

FAQ
What is the maximum allowable junction temperature for PR3005-T?
The absolute maximum junction temperature is +150°C, as specified in the datasheet's operating temperature range (Tj = –65°C to +150°C). Derating begins at TA = 90°C for the 3.0A average current rating, and thermal design must ensure Tj stays below 150°C under worst-case load and ambient conditions using RθJA = 15°C/W.
Can PR3005-T be used in full-wave bridge configurations?
Yes - PR3005-T is a single die rectifier and is commonly used as one quadrant in discrete full-wave bridge assemblies. Four units can form a complete bridge; its 600V VRRM and 150A IFSM provide sufficient margin for 230VAC inputs with transient protection, and its DO-201AD package allows standardized PCB layout for bridge footprints.
How does the 150ns reverse recovery time impact EMI in switch-mode designs?
A 150ns trr limits high-frequency ringing during diode turn-off, reducing conducted and radiated EMI in the 30–100MHz band. When paired with proper snubbing and layout (short traces, ground plane), it enables compliance with CISPR-22 Class B without additional filtering in low-to-medium power SMPS designs.
Is PR3005-T suitable for capacitive-input filter applications?
No - the datasheet explicitly states "For capacitive load, derate current by 20%." In capacitive-input rectifiers, peak current is significantly higher than average current, increasing thermal stress and risk of premature failure. Use only with resistive or inductive loads unless derated to 2.4A average and verified with thermal imaging under worst-case line/load conditions.
