Product details
Overview
PR3006G-T from Diodes Incorporated is a 3.0A fast recovery glass passivated rectifier diode in DO-201AD package, rated for 800V peak repetitive reverse voltage (VRRM), 1.3V forward voltage at 3.0A, and 125A non-repetitive surge current - used in AC/DC input stage rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR3006G-T datasheet, PR3006G-T pinout, PR3006G-T application, or PR3006G-T equivalent, key selection criteria include VRRM rating, trr of 500 ns, thermal resistance of 32°C/W, low IRM of 5.0 μA at 25°C, and DO-201AD mechanical compatibility with high-surge industrial front-end designs.
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 (−20% IO). Its glass passivated die construction ensures stable junction isolation and enhanced moisture resistance per J-STD-020C Level 1.
Reverse recovery time (trr = 500 ns) is measured under standardized conditions (IF = 0.5A, IR = 1A, Irr = 0.25A), and typical total capacitance is 50 pF at 1.0 MHz and 4.0V reverse bias - critical for EMI-sensitive switching power supply inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands up to 800V transient reverse voltage without breakdown in AC line rectification. |
| IO @ TA=55°C | 3.0 A - Continuous average forward current capability when leads are held at ambient at 9.5mm from case. |
| VFM @ IF=3.0A | 1.3 V - Forward conduction loss directly impacts efficiency and thermal rise in 3A-class power stages. |
| IFSM (8.3ms) | 125 A - Handles brief inrush surges common during cold-start of offline SMPS and motor drives. |
| trr | 500 ns - Fast recovery minimizes switching losses and reduces EMI generation in high-frequency rectifier applications. |
| IRM @ 25°C | 5.0 μA - Low leakage preserves hold-up energy and improves no-load efficiency in standby modes. |
| RθJA | 32 °C/W - Junction-to-ambient thermal resistance defines heatsinking requirements for sustained 3A operation. |
Pinout & Package
Package: DO-201AD molded plastic case (UL 94V-0), cathode indicated by band, tin-plated leads solderable per MIL-STD-202 Method 208, weight ≈1.12 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for AC or positive half-cycle source | Connected to transformer secondary or bridge input; carries full load current during conduction. |
| Cathode | Output terminal for rectified DC | Feeds bulk capacitor or downstream converter; polarity marking (band) prevents reverse installation. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Enables stable long-term reliability and humidity resistance in unsealed industrial enclosures. |
| 125A surge rating | Supports repeated cold-start events in 100–240VAC universal-input power supplies without degradation. |
| 500 ns trr | Reduces reverse recovery charge (Qrr), lowering switching losses in 50–100 kHz flyback and forward converters. |
| Low IRM (5.0 μA) | Minimizes standby power loss and improves compliance with Energy Star and EU CoC Tier 2 requirements. |
| DO-201AD package | Standardized through-hole footprint compatible with legacy PCB layouts and automated insertion equipment. |
Applications
| Industrial Power Supply Input Stage | LED Driver Bulk Rectification |
|---|---|
Use Scenario: AC line rectification in 30–100W open-frame industrial power supplies operating across 85–264VAC. IC Role / Device Role / Timing Role: Primary-side uncontrolled rectifier converting AC mains to DC bus prior to PFC or PWM controller stage. Use Value: 800V VRRM provides 2× safety margin over 264VAC peak (373V), while 125A IFSM handles transformer inrush without failure. |
Use Scenario: High-reliability rectification in outdoor LED streetlight drivers exposed to wide ambient temperature swings. IC Role / Device Role / Timing Role: Front-end diode in bridge or single-diode configuration feeding bulk electrolytic capacitor. Use Value: Glass passivation and −65°C to +150°C operating range ensure performance stability under thermal cycling and humidity stress. |
| AC Motor Drive Snubber Circuit | UPS Input Rectifier Module |
Use Scenario: Clamping and freewheeling path in IGBT-based single-phase motor inverters with regenerative braking. IC Role / Device Role / Timing Role: Fast recovery diode absorbing inductive kickback energy during IGBT turn-off. Use Value: 500 ns trr enables clean commutation at 10–20 kHz switching frequencies, reducing voltage overshoot and snubber losses. |
Use Scenario: Input rectifier in online double-conversion UPS systems requiring high surge tolerance and low leakage. IC Role / Device Role / Timing Role: Main rectifier in three-phase or split-phase input stage delivering DC link voltage to inverter section. Use Value: 32°C/W RθJA supports natural convection cooling in compact chassis; 5.0 μA IRM limits self-discharge during battery backup mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L08S | Same 800V VRRM and 3A IO, but TO-220AC package (RθJA = 25°C/W); trr = 60 ns (faster). | Requires heatsink mounting; better suited for forced-air-cooled higher-power designs (>50W). | Select when lower trr and superior thermal performance justify TO-220 layout change and added cost. |
| ES3J | DO-204AL (DO-15) package, 600V VRRM, 3A IO, trr = 35 ns; smaller footprint but lower voltage rating. | Limited to 230VAC-only systems; unsuitable for universal-input or 400VDC bus applications. | Choose only for space-constrained 600V-rated designs where 800V margin is not required. |
Compared with STTH3L08S and ES3J, PR3006G-T offers optimal balance of DO-201AD drop-in compatibility, 800V robustness, and cost-effective thermal performance for mid-power industrial rectification - without requiring board redesign or heatsink addition.

FAQ
Is PR3006G-T RoHS compliant?
Yes, PR3006G-T features lead-free finish and complies with RoHS Directive 2011/65/EU (Revision 13.2.2003), including exemptions for glass and high-temperature solder per EU Annex Notes 5 and 7.
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is +150°C. Derating begins above +55°C ambient, as shown in Figure 1: at +80°C ambient, IO reduces to approximately 2.2A for reliable long-term operation.
Can PR3006G-T be used in a full-wave bridge configuration?
Yes - each PR3006G-T diode is rated for single-phase half-wave operation, but four units can form a discrete full-wave bridge. Ensure matching VFM and trr across all four devices to avoid current imbalance and thermal runaway.
Why is PR3006G-T marked "NOT RECOMMENDED FOR NEW DESIGN"?
Diodes Incorporated issued this notice due to newer alternatives with improved trr, lower VFM, or enhanced packaging. However, PR3006G-T remains fully qualified, in active production, and supported for existing designs and legacy system maintenance.
