Product details
Overview
SFA1006GH from Taiwan Semiconductor is a 400 V, 10 A super fast recovery rectifier diode in TO-220AC package, featuring 35 ns reverse recovery time, 1.300 V forward voltage at 10 A and 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency switching power supplies.
For engineers reviewing the SFA1006GH datasheet, SFA1006GH pinout, SFA1006GH application, or SFA1006GH equivalent, key selection criteria include peak repetitive reverse voltage (400 V), surge current capability (125 A), junction-to-case thermal resistance (3.5 °C/W), and AEC-Q101 compliance status.
Technical Context
This super fast rectifier uses a single-die silicon PN junction optimized for low forward voltage and rapid carrier recombination. Its 35 ns trr enables operation in 100–500 kHz SMPS topologies without excessive switching loss.
The device operates across -55°C to +150°C junction temperature range with 10 µA max reverse leakage at 25°C and 400 µA at 100°C. Thermal performance is defined by 3.5 °C/W RθJC, supporting direct heatsink mounting via the TO-220AC case tab.

FAQ
What is the peak repetitive reverse voltage rating of the SFA1006GH?
The SFA1006GH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is specified in the Absolute Maximum Ratings table and confirmed across all official documentation versions, including Revision K2103. It defines the maximum DC or sinusoidal peak AC voltage the device can block continuously without breakdown under normal operating conditions.
Is the SFA1006GH qualified to AEC-Q101 standards?
Yes, the SFA1006GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the Features section of the datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and temperature cycling, making it suitable for automotive power electronics applications such as on-board chargers and DC-DC converters.
What is the forward voltage drop of the SFA1006GH at rated current?
The SFA1006GH exhibits a maximum forward voltage (VF) of 1.300 V at 10 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss baseline for thermal and efficiency calculations in power supply designs.
Does the SFA1006GH share the same package and pinout as other devices in the SFA100xG family?
Yes, the SFA1006GH uses the TO-220AC package with standardized anode/cathode/tab pinout shared across the entire SFA1001G–SFA1008G family. The cathode is connected to the metal tab, and polarity is marked on the device body-ensuring mechanical and electrical interchangeability within the series when voltage ratings align.
What is the reverse recovery time specification for the SFA1006GH?
The SFA1006GH has a typical reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is documented in the Electrical Specifications table and applies specifically to the SFA1005G–SFA1008G subgroup, confirming its suitability for high-frequency switching applications up to 500 kHz.
