Product details
Overview
PR2006G-T from Diodes Incorporated is a 2.0A fast recovery glass passivated rectifier diode in DO-15 package, rated for 800V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 2.0A, and 150ns reverse recovery time - deployed in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR2006G-T datasheet, PR2006G-T pinout, PR2006G-T application, or PR2006G-T equivalent, key selection criteria include VRRM derating under surge conditions, thermal resistance (50°C/W) in PCB layout, IRM leakage at 100°C, and compatibility with 60Hz half-wave resistive/inductive loads per JEDEC JESD24-11.
Technical Context
This device operates as a unidirectional silicon junction rectifier optimized for high-efficiency switching power conversion. Its glass passivation ensures stable surface characteristics under thermal cycling, while the DO-15 axial leaded package supports through-hole mounting with UL 94V-0 flammability rating and moisture sensitivity level 1.
The 150ns reverse recovery time (trr) enables operation in medium-frequency rectification up to ~20kHz without excessive switching loss, and the 80A non-repetitive surge rating (IFSM) accommodates line transients in offline SMPS input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum peak reverse voltage before breakdown; defines safe operating margin in 600–700VAC line applications. |
| IO @ TA=55°C | 2.0 A - Average forward current derated to ambient 55°C; requires heatsinking or airflow above 55°C ambient. |
| VFM @ IF=2.0A | 1.3 V - Forward voltage drop determining conduction loss (2.6W max at full load). |
| trr | 150 ns - Reverse recovery time measured at IF=0.5A, IR=1.0A, Irr=0.25A; limits usable frequency in flyback snubber networks. |
| RθJA | 50 °C/W - Junction-to-ambient thermal resistance; sets temperature rise under 2A DC load with standard PCB pad (9.5mm lead length). |
| IRM @ 100°C | 100 mA - Peak reverse leakage at elevated temperature; impacts standby power in high-temperature enclosed designs. |
Pinout & Package
DO-15 package: axial-leaded, molded plastic case with cathode band marking; polarity identified by single black band on cathode end; tin-plated leads compliant with MIL-STD-202 Method 208 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or transformer secondary; must withstand 80A surge during cold-start. |
| Cathode | Forward current exit / reverse blocking terminal | Marked with black band; ties to bulk capacitor positive rail; reverse leakage dominates standby loss. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die | Prevents surface degradation under humidity and thermal stress, extending reliability in industrial environments. |
| 80A IFSM surge rating | Withstands single half-sine surges up to 80A (8.3ms), enabling robustness against lightning-induced line spikes. |
| Low IRM at 100°C | 100mA max reverse leakage ensures <10mW standby dissipation in 700VDC bus hold-up circuits. |
| RoHS-compliant finish | Tin-plated leads meet EU Directive 2011/65/EU Annexes 5 & 7 exemptions for glass and high-temp solder. |
Applications
| Industrial AC/DC Power Supplies | LED Driver Input Rectification |
|---|---|
Use Scenario: Single-phase 230VAC input rectification feeding bulk capacitor in 30–100W open-frame power supply. IC Role / Device Role / Timing Role: Primary rectifier converting AC to pulsating DC; handles 2.0A average output with 80A surge tolerance. Use Value: 150ns trr minimizes switching loss during capacitor charging peaks, improving efficiency over standard recovery diodes. | Use Scenario: Off-line LED driver with passive PFC stage operating from 100–240VAC mains. IC Role / Device Role / Timing Role: Input bridge leg rectifier; blocks 800V reverse voltage during negative half-cycle. Use Value: 1.3V VFM reduces conduction loss in high-duty-cycle constant-current LED loads, lowering thermal stress on PCB. |
| UPS Input Stage | Motor Control Auxiliary Supply |
Use Scenario: Rectification in battery backup charger input stage exposed to generator-sourced distorted waveforms. IC Role / Device Role / Timing Role: Front-end diode handling intermittent 60Hz/50Hz input with harmonic-rich content. Use Value: Glass passivation maintains stable VRRM and IRM across 10,000+ thermal cycles in UPS cabinet environments. | Use Scenario: Auxiliary 24V DC supply derived from main AC line for gate driver ICs in 3-phase inverter modules. IC Role / Device Role / Timing Role: Isolated rectifier feeding linear regulator; operates continuously at 1.2A average load. Use Value: 50°C/W RθJA allows direct mounting on metal-core PCB without heatsink in space-constrained motor control 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 |
|---|---|---|---|
| STTH2R08 | Same VRRM (800V), lower VFM (1.15V), higher trr (200ns), TO-220AC package | Requires heatsink; suited for higher-power (>50W) continuous conduction mode designs | Select when lower conduction loss outweighs board space and thermal management complexity |
| ON Semiconductor MUR280E | Same DO-15 package, identical VRRM and IO, but 250ns trr and 1.45V VFM | Better surge robustness (100A IFSM), higher leakage (200mA @100°C) | Prefer where cost sensitivity and surge margin dominate over efficiency and leakage |
Compared with STTH2R08 and MUR280E, PR2006G-T offers optimal balance of low VFM, fast trr, and DO-15 form factor for compact 20–40W industrial power supplies where thermal budget and layout area are constrained.

FAQ
What is the maximum allowable ambient temperature for continuous 2.0A operation?
Per Figure 1 in the datasheet, full 2.0A average current is only rated at TA = 55°C. At 75°C ambient, derated current drops to ~1.4A. Layout must ensure 9.5mm lead length from case and adequate copper area to maintain junction temperature ≤150°C.
Can PR2006G-T replace PR2005G-T in a 600V design?
Yes - PR2006G-T has higher VRRM (800V vs. 600V) and identical IO, VFM, and package. It provides increased reverse voltage margin in 600V designs, especially under transient overvoltage or elevated temperature conditions where IRM increases.
Is PR2006G-T suitable for capacitive-input filter applications?
No - the datasheet explicitly states "For capacitive load, derate current by 20%." With 2.0A rated for resistive/inductive loads, capacitive-input operation limits average current to 1.6A to avoid excessive peak currents and thermal runaway.
Does the DO-15 package support automated optical inspection (AOI) after soldering?
Yes - the DO-15's axial symmetry, consistent cathode band contrast, and defined lead geometry enable reliable AOI detection. Tin plating and UL 94V-0 mold compound provide stable reflectivity and minimal shadowing during top-down inspection.
