Product details
Overview
SFAF1606GHC0G from Taiwan Semiconductor is a 16A, 400V repetitive peak reverse voltage (VRRM) super fast rectifier diode in ITO-220AC package, featuring 1.300V forward voltage at 16A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC-DC converters.
For engineers reviewing the SFAF1606GHC0G datasheet, SFAF1606GHC0G pinout, SFAF1606GHC0G application, or SFAF1606GHC0G equivalent, key selection criteria include VRRM=400V, VF=1.300V @16A, trr=35ns, TJ(max)=150°C, and AEC-Q101 qualification status - all critical for switching power supply efficiency and thermal robustness.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for high-speed switching. Its 35ns reverse recovery time and low junction capacitance (100pF @1MHz, 4V) minimize switching losses in 50–500kHz SMPS topologies.
The ITO-220AC package provides 1.3°C/W junction-to-case thermal resistance and supports 0.56 N·m mounting torque. Matte tin-plated leads meet J-STD-002 solderability, and UL Recognition #E-326243 confirms safety compliance.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of SFAF1606GHC0G?
The SFAF1606GHC0G has a VRRM rating of 400 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2105). This value defines the highest reverse voltage the device can block repeatedly without breakdown under specified thermal conditions.
Is SFAF1606GHC0G qualified to AEC-Q101 standards?
Yes, SFAF1606GHC0G is AEC-Q101 qualified - indicated by the "H" suffix in the ordering code and explicitly stated in the FEATURES section. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing for automotive power applications.
What is the forward voltage (VF) of SFAF1606GHC0G at rated current?
The forward voltage of SFAF1606GHC0G is 1.300 V maximum at IF = 16 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulse conditions (PW = 0.3 ms) and directly impacts conduction loss in power converter designs.
What package type does SFAF1606GHC0G use, and is the tab electrically active?
SFAF1606GHC0G uses the ITO-220AC package, where the metal tab is the cathode terminal and electrically active. The datasheet confirms polarity marking on the device body and specifies the tab as part of the cathode connection - requiring electrical isolation from the heatsink unless circuit topology permits common-cathode mounting.
What is the reverse recovery time (trr) specification for SFAF1606GHC0G?
The reverse recovery time (trr) of SFAF1606GHC0G is 35 ns maximum, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency DC-DC converters and is verified per JEDEC-standard test conditions.
