Product details
Overview
PR1006G-T from Diodes Incorporated is a 1.0A fast recovery glass passivated rectifier diode in DO-41 package, rated for 800V peak repetitive reverse voltage (VRRM), 1.3V forward voltage drop at 1.0A (VFM), and 30A non-repetitive surge current (IFSM), used in AC/DC front-end rectification for industrial power supplies and LED drivers.
For engineers reviewing the PR1006G-T datasheet, PR1006G-T pinout, PR1006G-T application, or PR1006G-T equivalent, key selection criteria include VRRM rating, tRR of 500 ns, low IRM (50 µA @ +100°C), thermal resistance (RθJA = 95 °C/W), and DO-41 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device operates as a unidirectional silicon PN junction rectifier optimized for high-efficiency switching-mode power conversion. Its glass passivated die construction ensures stable reverse characteristics and robust surge tolerance up to 30A for 8.3 ms half-sine pulses.
The 500 ns reverse recovery time (tRR) enables operation in 20–100 kHz SMPS topologies without excessive switching loss, while its 15 pF typical junction capacitance (CT) minimizes high-frequency noise coupling in EMI-sensitive designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Withstands peak reverse transients in 600 VAC line applications after bridge rectification |
| IO @ TA=+55°C | 1.0 A - Continuous DC output current capability under standard heatsink-free PCB mounting |
| VFM @ IF=1.0A | 1.3 V - Contributes ≤1.3 W conduction loss per diode in series rectifier configurations |
| tRR | 500 ns - Enables efficient operation in 20–100 kHz flyback and forward converters |
| IRM @ +100°C | 50 µA - Limits leakage-induced standby power loss in high-temperature environments |
| RθJA | 95 °C/W - Requires ≥1.5 cm² copper pour for safe operation at full load in still air |
| CT @ 1 MHz, 4 V | 15 pF - Reduces high-frequency displacement current in snubberless designs |

Use Value: 800 V rating accommodates 277 VAC utility lines and transient spikes; glass passivation ensures stability during frequent charge/discharge cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RS1M-T | VRRM = 1000 V, tRR = 500 ns, IO = 1.0 A, same DO-41 package | Higher voltage margin; identical thermal and switching performance | Select when >800 V transient immunity is required beyond IEC 61000-4-5 Level 4 |
| FR107 | VRRM = 1000 V, tRR = 500 ns, IO = 1.0 A, DO-41, but higher VFM (1.7 V) | Same surge rating but higher conduction loss; RoHS-compliant but not "Green" certified | Acceptable where cost sensitivity outweighs 0.4 V VFM penalty and thermal derating is managed |
Compared with RS1M-T and FR1007, PR1006G-T offers optimal balance of 800 V rating, 1.3 V VFM, and Diodes Inc.'s Green/RoHS-3 compliance-making it preferred for energy-efficient, thermally constrained, and environmentally regulated designs.

FAQ
What is the maximum junction temperature for continuous operation of PR1006G-T?
The PR1006G-T has an operating junction temperature range of –65°C to +150°C. For reliable long-term operation at 1.0 A average current, thermal design must ensure TJ remains ≤125°C under worst-case ambient and power dissipation conditions, typically requiring ≥1.5 cm² of 2-oz copper on the PCB.
Is PR1006G-T compatible with lead-free reflow soldering processes?
Yes - PR1006G-T features matte tin-plated leads qualified per J-STD-020 moisture sensitivity level 1 and is rated for peak reflow temperatures up to 260°C. Its DO-41 package withstands standard lead-free solder profiles without delamination or parameter shift.
How does the 500 ns reverse recovery time impact EMI in switch-mode designs?
A 500 ns tRR limits high-frequency ringing during turn-off, reducing broadband EMI generation in the 1–30 MHz range. When paired with appropriate snubbers and layout practices, it meets CISPR-22 Class B conducted emissions limits without additional filtering in most 65–100 kHz flyback converters.
Can PR1006G-T replace PR1007G in a 1000 V design?
No - PR1006G-T is rated for 800 V VRRM and must not be substituted for PR1007G (1000 V) in circuits exposed to peak reverse voltages exceeding 800 V. Doing so risks premature avalanche breakdown and catastrophic failure under transient overvoltage conditions.
