Product details
Overview
FR106-T from Diodes Incorporated is a 1.0A fast recovery rectifier diode in DO-41 axial package, rated for 800V maximum recurrent peak reverse voltage (VRRM), 1.3V max forward voltage at 1.0A, and 250ns reverse recovery time (Trr), used in AC/DC input stage rectification of offline power supplies and auxiliary power rails.
For engineers reviewing the FR106-T datasheet, FR106-T pinout, FR106-T application, or FR106-T equivalent, key selection criteria include VRRM margin for 230VAC surge tolerance, Trr impact on switching loss in high-frequency flyback snubbers, thermal derating above 75°C ambient, and DO-41 lead-form compatibility with through-hole PCB layouts.
Technical Context
This device operates as a unidirectional current switch in single-phase half-wave rectification circuits, with junction-to-ambient thermal resistance of 50°C/W under standard PC board mounting (9.5mm lead length). Its 15pF junction capacitance at 4V reverse bias supports stable high-frequency behavior up to ~10MHz.
The 250ns reverse recovery time enables efficient operation in 20–100kHz SMPS front-end stages, while its 30A non-repetitive surge rating withstands inrush currents from cold-started capacitive inputs per JEDEC Method 208.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800V - Withstands peak line voltage + safety margin for 230VAC mains applications |
| IF(AV) | 1.0A @ TA = 75°C - Continuous output capability in compact open-frame adapters |
| VF | 1.3V @ IF = 1.0A - Contributes ≤1.3W conduction loss at full load |
| Trr | 250ns - Limits reverse recovery charge (Qrr ≈ 6.25nC) to reduce snubber dissipation |
| CJ | 15pF @ VR = 4V - Minimizes capacitive coupling noise in EMI-sensitive input filters |
| IR | 5.0µA @ 25°C - Ensures low standby leakage in energy-efficient standby circuits |
Pinout & Package
DO-41 molded plastic axial-leaded package (UL 94V-0 rated); cathode identified by band; weight ≈ 0.35g; mountable in any orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction path | Connects to AC source or transformer secondary; carries full load current during positive half-cycle |
| Cathode | Output terminal for forward conduction path | Connects to bulk capacitor or downstream DC rail; polarity-marked with band for assembly verification |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 250ns - Reduces switching losses and EMI generation in 50–100kHz flyback converters |
| High VRRM rating | 800V - Supports universal-input (90–264VAC) designs without series stacking |
| Low leakage current | 5.0µA @ 25°C - Maintains low no-load power consumption in Energy Star-compliant adapters |
| Robust surge handling | 30A IFSM (8.3ms) - Survives cold-start surges from 100µF+ input capacitors |
Applications
| AC/DC Adapter Input Stage | Industrial Control Auxiliary Supply |
|---|---|
Use Scenario: Rectifying 50/60Hz transformer output in wall-wart adapters delivering 5–12V/1A. IC Role / Device Role / Timing Role: Primary-side unidirectional current valve enabling capacitor-input filter operation. Use Value: 1.3V VF ensures <1.5W conduction loss at full load; DO-41 form factor fits legacy through-hole layouts. | Use Scenario: Generating isolated +15V bias rail for PLC I/O modules operating in -25°C to +70°C environments. IC Role / Device Role / Timing Role: Half-wave rectifier feeding linear regulator; handles intermittent 100ms overloads. Use Value: 30A IFSM withstands relay-coil turn-off spikes; -65°C to +175°C TJ range supports extended industrial temp operation. |
| LED Driver Bulk Rectification | Appliance Power Supply Snubber Path |
Use Scenario: Off-line rectification in constant-current LED drivers powering streetlight modules. IC Role / Device Role / Timing Role: Front-end AC input rectifier preceding PFC stage; operates at 50Hz with low thermal cycling stress. Use Value: 50°C/W RθJA allows natural convection cooling on FR4; 800V VRRM accommodates 300VAC transients. | Use Scenario: Clamp diode in RCD snubber network across flyback transformer primary winding. IC Role / Device Role / Timing Role: Fast-recovery path for leakage inductance energy dissipation during MOSFET turn-off. Use Value: 250ns Trr minimizes voltage overshoot; 15pF CJ avoids resonant ringing with snubber capacitor. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FR107-T | 1000V VRRM, 500ns Trr, same DO-41 package and IF(AV) | Higher voltage margin for 277VAC lighting systems; slower recovery increases snubber loss | Select when >800V line transients are expected; avoid in high-frequency snubbers |
| PR1006G | 800V VRRM, 150ns Trr, TO-220AC package, 1.5A IF(AV) | Surface-mount alternative with lower Trr and higher current; requires heatsink for >0.8A | Prefer for new SMT designs needing faster recovery; not drop-in for DO-41 footprints |
Compared with FR107-T, FR106-T offers 250ns faster recovery for reduced snubber loss but sacrifices 200V VRRM headroom; versus PR1006G, it provides legacy through-hole compatibility at the cost of higher Trr and lower thermal current rating.

FAQ
What is the maximum allowable junction temperature for FR106-T?
The absolute maximum junction temperature (TJ) is +175°C, with storage temperature matching this range. Operation above +125°C requires derating of average forward current per Figure 1 in the datasheet, where I(AV) drops to 0.6A at +100°C ambient with 9.5mm leads.
Can FR106-T be used in full-wave bridge configurations?
Yes - four FR106-T diodes can construct a discrete full-wave bridge rectifier. Each device must handle half the peak inverse voltage (PIV) of the transformer secondary, so a 400V RMS secondary yields ~565V PIV, remaining within the 800V VRRM rating with margin.
Is FR106-T compliant with RoHS and REACH regulations?
Yes - FR106-T meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound confirmed in Diodes Incorporated's official compliance documentation.
How does FR106-T compare to standard silicon rectifiers like 1N4007?
FR106-T offers 250ns reverse recovery vs. 30µs for 1N4007, reducing switching loss and EMI in high-frequency applications. It shares the same DO-41 package and 1.0A rating but trades higher VF (1.3V vs. 1.1V) for faster recovery and tighter leakage control (5µA vs. 50µA).
