Product details
Overview
SF807G from Taiwan Semiconductor is an AEC-Q101-qualified 8A, 600V super fast rectifier diode in TO-220AB package, featuring 1.700 V forward voltage at 4A/25°C, 35 ns reverse recovery time, and 50 pF junction capacitance per diode - deployed in high-efficiency DC-DC converters and freewheeling paths in automotive power supplies.
For engineers reviewing the SF807G datasheet, SF807G pinout, SF807G application, or SF807G equivalent, key selection criteria include its 600V VRRM, dual-die configuration, thermal resistance of 3°C/W, AEC-Q101 qualification status, and compatibility with high-surge (125A IFSM) switching environments.
Technical Context
The SF807G implements a super fast recovery rectifier architecture optimized for high-frequency switching applications, with trr ≤ 35 ns under IF = 0.5A / IR = 1.0A / Irr = 0.25A conditions and VF = 1.700 V at 4A and 25°C. Its dual-die construction enables balanced current sharing in parallel configurations.
Thermally, it delivers RθJC = 3°C/W and operates across –55°C to +150°C junction temperature range. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements in its TO-220AB molded package.

FAQ
What is the peak repetitive reverse voltage rating of the SF807G?
The SF807G has a peak repetitive reverse voltage (VRRM) rating of 600 V, verified per the manufacturer's absolute maximum ratings table. This allows the SF807G to safely block transients up to 600 V in DC-link and output rectification applications without avalanche breakdown. The SF807G is the highest-voltage member of the SF801G–SF808G family.
Is the SF807G AEC-Q101 qualified?
Yes, the SF807G is AEC-Q101 qualified - confirmed in the FEATURES section and ordering code notes (SF807GH denotes AEC-Q101 version). The SF807G undergoes stress testing per AEC-Q101 Rev D, including HTGB, HTRB, and temperature cycling, making it suitable for automotive underhood power modules and ADAS subsystems.
What is the forward voltage drop of the SF807G at rated current?
The SF807G exhibits a typical forward voltage (VF) of 1.700 V at 4 A and 25°C, as specified in the ELECTRICAL SPECIFICATIONS table. At full rated current (8 A), VF increases due to resistive heating but remains within design margins for high-efficiency SMPS output stages where thermal management is implemented.
Does the SF807G have a dual-die configuration, and why does it matter?
Yes, the SF807G uses a dual-die configuration inside its TO-220AB package - explicitly stated in the KEY PARAMETERS section. This architecture improves current sharing, enhances thermal distribution, and increases reliability margin compared to single-die 8A rectifiers, especially under unbalanced PCB layout or asymmetric heatsinking conditions.
What is the reverse recovery time of the SF807G, and how is it measured?
The SF807G has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the ELECTRICAL SPECIFICATIONS table. This value reflects its super fast recovery performance, critical for minimizing switching losses and EMI in high-frequency converters operating above 100 kHz.
