Product details
Overview
PR2005G-T from Diodes Incorporated is a 2.0A fast recovery glass passivated rectifier diode in DO-15 package, rated for 600V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 2.0A, and 150ns reverse recovery time - used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR2005G-T datasheet, PR2005G-T pinout, PR2005G-T application, or PR2005G-T equivalent, key selection criteria include VRRM derating margin, thermal resistance (50°C/W), surge capability (80A IFSM), and low IRM (5.0mA @ 25°C) for high-reliability offline rectification.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching-mode power conversion. Its glass passivation ensures stable junction integrity under thermal cycling, while the DO-15 axial leaded package supports through-hole mounting with 0.4g mass and UL 94V-0 flammability rating.
The 150ns trr enables operation up to ~100kHz in discontinuous conduction mode flyback designs; its 50°C/W junction-to-ambient thermal resistance requires minimum 9.5mm lead length for full 2.0A IO rating at TA = 55°C per JEDEC conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600V - withstands peak line transients in 230VAC mains applications with ≥2× safety margin |
| IO @ TA=55°C | 2.0A - continuous average forward current with leads held at ambient at 9.5mm from case |
| VFM @ IF=2.0A | 1.3V - contributes ≤2.6W conduction loss at full load, critical for thermal budgeting |
| IFSM (8.3ms) | 80A - survives cold-start inrush into bulk capacitors without failure |
| trr | 150ns - limits switching losses and EMI in 50–100kHz SMPS front-end stages |
| IRM @ 25°C | 5.0mA - low leakage preserves efficiency in standby and light-load conditions |
| RθJA | 50°C/W - defines minimum PCB copper area and airflow needed for thermal compliance |
Pinout & Package
DO-15 molded plastic package with axial leads; cathode identified by band; tin-plated terminals compliant with MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | AC input connection point | Accepts alternating input; must be routed with clearance for 600V working voltage |
| Cathode (Lead 2, banded end) | DC output connection point | Delivers rectified positive voltage; polarity marking prevents reverse installation |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable long-term reliability under humidity and thermal stress per J-STD-020C Level 1 |
| Fast recovery (150ns) | Reduces switching loss and di/dt-induced ringing in high-frequency rectifier applications |
| 80A non-repetitive surge rating | Supports robust startup behavior in capacitor-input filter designs without derating |
| Low IRM (5.0mA @ 25°C) | Minimizes standby power loss in energy-efficient power adapters and LED drivers |
| RoHS-compliant finish | Meets EU Directive Annex Notes 5 & 7 exemptions for glass and high-temp solder |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|

Use Value: 50°C/W RθJA allows direct mounting on metal-core PCB without heatsink in space-constrained 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 |
|---|---|---|---|
| STTH2R06 | VRRM = 600V, trr = 120ns, VFM = 1.25V @ 2A, DO-15 | Slightly faster recovery and lower VF, but higher cost and limited tape-and-reel availability | Preferred where EMI reduction is critical and BOM cost premium is acceptable |
| ON Semi MUR260 | VRRM = 600V, trr = 35ns, VFM = 1.7V @ 2A, DO-15 | Ultra-fast recovery improves high-frequency efficiency but increases conduction loss | Select when operating >200kHz; avoid in thermally constrained 50/60Hz applications due to higher VF |
Compared with STTH2R06 and MUR260, PR2005G-T balances low VF, moderate trr, and cost-effective DO-15 packaging - making it optimal for mainstream 50–100kHz industrial rectification where thermal and EMI trade-offs are tightly coupled.

FAQ
What is the maximum allowable junction temperature for PR2005G-T?
The absolute maximum junction temperature is +150°C, and the storage temperature range matches this limit. Operation above 125°C requires derating IO below 2.0A per the Fig. 1 derating curve; sustained operation at Tj > 135°C may accelerate parametric drift in IRM and trr.
Can PR2005G-T replace PR2004G-T in a 400V design?
Yes - PR2005G-T has VRRM = 600V versus PR2004G-T's 400V, providing greater transient margin. However, VFM remains identical (1.3V), so no thermal redesign is needed; layout clearance must accommodate the higher voltage rating.
Is PR2005G-T suitable for use in a capacitive-input filter?
No - the datasheet explicitly states that current must be derated by 20% for capacitive loads. For such topologies, select a part rated ≥2.5A average current or implement inrush limiting to stay within the 2.0A IO limit.
Does PR2005G-T meet lead-free assembly requirements?
Yes - it features lead-free finish and is RoHS compliant per EU Directive Annex Notes 5 and 7, with exemptions applied for glass and high-temperature solder. It passes reflow profiles up to 260°C per J-STD-020C Level 1 moisture sensitivity.
