Product details
Overview
SF1JDF-13 from Diodes Incorporated is a 600 V, 1.0 A surface-mount super-fast rectifier diode in D-FLAT package, designed for high-efficiency secondary rectification and freewheeling in AC-DC/DC-DC converters operating at elevated temperatures. It delivers VF = 1.7 V @ 1 A, tRR = 35 ns, IR ≤ 5 µA @ 25°C, and supports PFC boost stage applications in consumer power adapters.
For engineers reviewing the SF1JDF-13 datasheet, SF1JDF-13 pinout, SF1JDF-13 application, or SF1JDF-13 equivalent, key selection criteria include reverse voltage rating (600 V), ultrafast recovery time (35 ns), low leakage (5 µA), thermal resistance (RθJA = 87 °C/W), and D-FLAT package compatibility with high-density PCB layouts.
Technical Context
This super-fast rectifier employs a planar epitaxial silicon junction optimized for minimal reverse recovery charge (Qrr) and low forward conduction loss. Its glass-passivated chip structure ensures stable performance across -55°C to +150°C operating range and enables reliable operation under repetitive surge conditions (IFSM = 30 A).
The D-FLAT package provides low-profile mounting (max height 1.10 mm), excellent thermal coupling to PCB copper pads, and polarity identification via cathode band. Terminal metallization uses matte tin over copper leadframe, ensuring robust solderability per MIL-STD-202 Method 208.
Key Specifications

|---|---|
| VRRM | 600 V - Withstands peak reverse voltage in PFC boost and DC-DC flyback outputs without breakdown |
| IO @ TT=110°C | 1.0 A - Continuous average forward current capability under thermally constrained board conditions |
| VF @ IF=1A | 1.7 V - Low conduction loss enabling >90% efficiency in 12–24 V output stages |
| tRR | 35 ns - Enables switching frequencies up to 500 kHz with minimal switching loss and EMI |
| IR @ 25°C | ≤5 µA - Ensures minimal standby power loss in energy-efficient chargers and adapters |
| RθJA | 87 °C/W - Requires ≥0.2" × 0.25" copper pad on FR-4 for safe thermal management at full load |
| CT @ 1 MHz | 20 pF - Limits capacitive coupling noise in high dv/dt gate-drive or snubber circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super-fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB160-TB | VRRM = 60 V, VF = 0.75 V @ 1 A, tRR ≈ 50 ns (Schottky), not rated >125°C | Only suitable for low-voltage DC-DC outputs; cannot replace SF1JDF-13 in 600 V PFC or flyback primary-side rectification | Select only when VRRM ≤ 100 V and junction temperature remains <125°C |
| ES1J-E3/54 | VRRM = 600 V, VF = 1.7 V @ 1 A, tRR = 35 ns, same D-FLAT package but RθJA = 95 °C/W | Identical electrical specs but higher thermal resistance requires larger copper area or derating above 85°C ambient | Acceptable drop-in replacement if board layout allows ≥25% larger thermal pad area |
Compared with SB160-TB and ES1J-E3/54, SF1JDF-13 uniquely balances 600 V rating, 35 ns recovery, and 87 °C/W thermal resistance in a standardized D-FLAT footprint-making it optimal for thermally constrained, high-input-voltage consumer power stages where reliability across full industrial temperature range is mandatory.

FAQ
What is the maximum junction temperature rating for SF1JDF-13?
The SF1JDF-13 has an operating junction temperature range of –55°C to +150°C, verified per datasheet DS39431 Rev. 2. This rating is maintained under specified thermal conditions: 1.0 A average forward current with device mounted on a 0.4" × 0.5", 2 oz copper pad on FR-4 PCB.
Is SF1JDF-13 compatible with lead-free reflow profiles?
Yes. SF1JDF-13 features matte tin-plated terminals and is qualified for standard lead-free reflow profiles (peak temperature ≤ 260°C, per JEDEC J-STD-020). Its moisture sensitivity level is Class 1, eliminating bake requirements prior to assembly.
Does SF1JDF-13 have a specified reverse recovery charge (Qrr)?
No Qrr value is published in the official DS39431 datasheet. However, tRR = 35 ns (measured at IF = 0.5 A, IR = 1 A, IRR = 0.25 A) and VF = 1.7 V indicate low stored charge-consistent with super-fast rectifier classification and suitable for quasi-resonant and CCM flyback designs.
Can SF1JDF-13 be used in place of SF1DDF-13 or SF1GDF-13?
Yes, as a direct functional upgrade: SF1JDF-13 offers identical D-FLAT packaging and pinout but extends VRRM from 200 V (SF1DDF) or 400 V (SF1GDF) to 600 V. No layout change is needed, though system-level voltage stress analysis must confirm 600 V margin is appropriate for the application.
