Product details
Overview
SFT16GH from Taiwan Semiconductor is a 400 V, 1 A AEC-Q101-qualified super fast rectifier diode in TS-1 package, featuring 1.30 V forward voltage at 1 A and 35 ns reverse recovery time, used for freewheeling and DC-DC converter output stages in automotive power supplies.
For engineers reviewing the SFT16GH datasheet, SFT16GH pinout, SFT16GH application, or SFT16GH equivalent, key selection criteria include peak reverse voltage (400 V), surge current rating (30 A), junction-to-ambient thermal resistance (100 °C/W), AEC-Q101 qualification status, and TS-1 package compatibility with high-density PCB layouts.
Technical Context
The SFT16GH is a single-die silicon planar super fast recovery rectifier optimized for switching-mode power conversion. Its 35 ns trr and low 1.30 V VF at 1 A enable high-efficiency operation in 100–500 kHz DC-DC topologies while maintaining robust 30 A IFSM capability under 8.3 ms half-sine surge conditions.
Thermally, the TS-1 package delivers 100 °C/W RθJA, supporting continuous 1 A conduction up to +125 °C ambient when mounted on standard FR-4 with minimal copper area. Reverse leakage remains ≤100 µA at TJ = 125 °C, ensuring stable blocking in high-temperature automotive environments.

FAQ
What is the peak repetitive reverse voltage rating of the SFT16GH?
The SFT16GH has a peak repetitive reverse voltage (VRRM) rating of 400 V, verified per JESD201 and confirmed in the official Taiwan Semiconductor datasheet Version J2104. This rating defines the maximum reverse voltage the SFT16GH can block repeatedly without breakdown under normal operating conditions, making it suitable for 24 V and 48 V automotive and industrial DC bus-derived power supplies.
Is the SFT16GH qualified for automotive applications?
Yes, the SFT16GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the "FEATURES" section of the Taiwan Semiconductor datasheet. The SFT16GH undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TCT), and highly accelerated temperature-humidity bias (HAST) to meet automotive reliability standards for powertrain and body electronics.
What is the forward voltage drop of the SFT16GH at 1 A and 25°C?
The forward voltage (VF) of the SFT16GH is 1.30 V at 1 A and TJ = 25°C, per the "ELECTRICAL SPECIFICATIONS" table in the official datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss during steady-state operation in DC-DC converters, directly impacting system efficiency and thermal design.
What package type does the SFT16GH use, and what are its key mechanical features?
The SFT16GH uses the TS-1 surface-mount package, defined in the "MECHANICAL DATA" section. Key features include UL 94V-0 flammability-rated molding compound, pure tin-plated leads compliant with J-STD-002, cathode polarity indicated by a visible band, and a mass of approximately 0.200 g. The TS-1 footprint supports automated reflow assembly and provides reliable thermal dissipation for 1 A continuous operation.
What is the reverse recovery time (trr) specification for the SFT16GH?
The reverse recovery time (trr) of the SFT16GH is 35 ns, specified under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the "ELECTRICAL SPECIFICATIONS" table. This parameter reflects the diode's speed during turn-off transitions and is critical for minimizing switching losses and EMI in high-frequency DC-DC converters using the SFT16GH as a freewheeling or output rectifier.
