Product details
Overview
SFF502GHC0G from Taiwan Semiconductor is a 100 V, 5 A AEC-Q101-qualified super fast rectifier diode in ITO-220AB package, featuring 0.98 V forward voltage at 2.5 A and 35 ns reverse recovery time, used in automotive DC-DC converters and switching inverters.
For engineers reviewing the SFF502GHC0G datasheet, SFF502GHC0G pinout, SFF502GHC0G application, or SFF502GHC0G equivalent, key selection criteria include peak reverse voltage rating (100 V), thermal resistance (5.5 °C/W), surge capability (70 A), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This device is a single-die, dual-terminal super fast recovery rectifier optimized for high-frequency switching applications. It delivers low conduction loss (VF = 0.98 V @ 2.5 A, 25 °C) and fast switching (trr = 35 ns) with low junction capacitance (70 pF @ 1 MHz, 4 V).
The ITO-220AB package enables direct heatsink mounting with 0.56 N·m max torque and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements, supporting automotive under-hood environments.

FAQ
What is the peak repetitive reverse voltage rating of the SFF502GHC0G?
The SFF502GHC0G has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is specified in the Absolute Maximum Ratings table and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate clamping and snubber components in the SFF502GHC0G application circuit.
Is the SFF502GHC0G qualified for automotive use?
Yes, the SFF502GHC0G is AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section. This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing-ensuring reliability for under-hood automotive power systems using the SFF502GHC0G.
What is the forward voltage drop of the SFF502GHC0G at typical operating conditions?
The SFF502GHC0G exhibits a typical forward voltage (VF) of 0.98 V at 2.5 A and 25 °C, per the Electrical Specifications table. This low VF directly reduces conduction losses in high-current DC-DC stages, making the SFF502GHC0G especially effective in 12 V automotive auxiliary power supplies.
Does the SFF502GHC0G have a defined reverse recovery time?
Yes, the SFF502GHC0G has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic minimizes switching losses and EMI in high-frequency converters, a key design advantage of the SFF502GHC0G in modern SMPS designs.
What package type does the SFF502GHC0G use, and how is thermal management addressed?
The SFF502GHC0G uses the ITO-220AB package, which features an electrically isolated metal tab thermally coupled to the cathode. Its junction-to-case thermal resistance is 5.5 °C/W, enabling efficient heat transfer to external heatsinks. Mounting torque must not exceed 0.56 N·m, and the package complies with UL 94V-0 and JESD201 Class 2 whisker standards-critical for long-term reliability of the SFF502GHC0G in automotive environments.
