Product details
Overview
SF2JDF-13 from Diodes Incorporated is a 600 V, 2.0 A surface-mount super-fast rectifier in D-FLAT package, designed as a boost diode in PFC circuits and for secondary rectification/freewheeling in high-frequency AC-DC and DC-DC converters operating up to +150°C. It delivers 1.7 V max forward voltage at 2 A, 35 ns reverse recovery time, and 5 µA max reverse leakage at 25°C.
For engineers reviewing the SF2JDF-13 datasheet, SF2JDF-13 pinout, SF2JDF-13 application, or SF2JDF-13 equivalent, key selection criteria include peak repetitive reverse voltage (600 V), thermal resistance junction-to-terminal (30 °C/W), low-profile D-FLAT packaging, RoHS-compliant matte tin terminals, and suitability for high-temperature consumer power supplies.
Technical Context
This super-fast rectifier operates with single-phase half-wave 60 Hz resistive/inductive loads and requires 20% current derating for capacitive loads. Its 35 ns reverse recovery time enables efficient operation in high-frequency switching topologies such as active clamp flyback and LLC resonant converters.
The device features glass passivation for reliability under thermal cycling and humidity stress, and its D-FLAT package provides low thermal resistance (30 °C/W junction-to-terminal) when mounted on standard FR-4 PCBs with defined copper pad geometry.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06S | 600 V, 2 A, 1.7 V VF, 50 ns tRR, TO-277 package | Higher thermal resistance (45 °C/W) and larger footprint than D-FLAT | Select when legacy TO-277 layout reuse is required and board height >1.8 mm is acceptable |
| ES2J | 600 V, 2 A, 1.7 V VF, 35 ns tRR, SMA package | SMA has higher RθJA (75 °C/W) and lower current derating above 75°C | Select only for low-power (<1.2 A avg) designs where D-FLAT footprint cannot be accommodated |
Compared with STTH2R06S and ES2J, SF2JDF-13 offers superior thermal performance in constrained spaces due to its D-FLAT package's 30 °C/W RθJT, enabling higher sustained current in thermally dense consumer power modules.

FAQ
What is the maximum allowable junction temperature for SF2JDF-13 during continuous operation?
The absolute maximum junction temperature is +150°C, verified per JEDEC JESD22-A108. Derating begins at +88°C terminal temperature, where average forward current drops linearly to zero at +150°C. Thermal design must ensure RθJT × PLOSS + TT ≤ 150°C under worst-case ambient and airflow conditions.
Can SF2JDF-13 replace SF2DDF-13 or SF2GDF-13 in an existing design?
Yes, but only if the circuit requires 600 V blocking capability. SF2JDF-13 has higher VRRM (600 V) than SF2DDF-13 (200 V) and SF2GDF-13 (400 V); substituting it into lower-voltage designs adds unnecessary cost and may increase forward voltage slightly due to higher doping gradients.
Is SF2JDF-13 suitable for use in automotive infotainment power supplies?
No - SF2JDF-13 is qualified for commercial temperature range (−55°C to +150°C) but lacks AEC-Q101 qualification. For automotive applications, Diodes' AEC-Q101-qualified equivalents like SB2J060Q (600 V, 2 A, DFN2020) must be used to meet PPAP and stress test requirements.
How does the D-FLAT package improve thermal performance compared to SMA or DO-214AA?
D-FLAT reduces junction-to-terminal thermal resistance to 30 °C/W versus 55–75 °C/W for SMA/DO-214AA, due to its exposed copper leadframe and minimal mold compound thickness. This allows 35% higher power dissipation at the same PCB copper area, critical for fanless consumer enclosures.
