Product details
Overview
SFAF1606G from Taiwan Semiconductor is a 400 V, 16 A super fast rectifier diode in ITO-220AC package, featuring 1.300 V forward voltage at 16 A and 25°C, 35 ns reverse recovery time, and 100 pF junction capacitance - used in high-efficiency DC/DC converters and switching inverters.
For engineers reviewing the SFAF1606G datasheet, SFAF1606G pinout, SFAF1606G application, or SFAF1606G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), surge current capability (200 A), thermal resistance (1.3 °C/W), AEC-Q101 qualification status, and UL recognition (E-326243).
Technical Context
The SFAF1606G is a single-die, glass-passivated super fast recovery rectifier optimized for high-frequency switching applications. Its 35 ns trr and low VF enable reduced switching losses in SMPS topologies, while its 1.3 °C/W RθJC supports stable thermal performance under continuous 16 A conduction.
Designed for operation across -55°C to +150°C junction temperature range, it delivers 10 µA max reverse leakage at 25°C and 400 µA at 100°C under rated 400 V reverse bias - meeting stringent reliability requirements for automotive and industrial power conversion.

FAQ
What is the maximum repetitive peak reverse voltage rating for SFAF1606G?
The SFAF1606G has a maximum repetitive peak reverse voltage (VRRM) of 400 V, as confirmed in the Absolute Maximum Ratings table. This rating defines the highest reverse-biased voltage the device can block repeatedly without avalanche breakdown under normal operating conditions at TA = 25°C.
Is SFAF1606G AEC-Q101 qualified?
The base SFAF1606G is not automatically AEC-Q101 qualified; however, the variant SFAF1606GH - indicated by the "H" suffix in the ordering code - is explicitly AEC-Q101 qualified per the Ordering Information section. Always verify the full part number suffix when selecting for automotive applications.
What is the forward voltage drop of SFAF1606G at rated current?
The SFAF1606G exhibits a typical forward voltage (VF) of 1.300 V at IF = 16 A and TJ = 25°C, as specified in the Electrical Specifications table. This value increases with junction temperature and is measured under pulsed conditions (PW = 0.3 ms).
Does SFAF1606G have an electrically isolated package?
Yes, the SFAF1606G uses the ITO-220AC package, where the metal tab is electrically isolated from both the anode and cathode terminals. This isolation enables direct mounting to a common heatsink without additional insulating hardware, simplifying thermal management in high-voltage systems.
What is the junction-to-case thermal resistance of SFAF1606G?
The SFAF1606G has a typical junction-to-case thermal resistance (RθJC) of 1.3 °C/W, as listed in the Thermal Performance section. This value is critical for calculating maximum allowable power dissipation and heatsink requirements under steady-state conduction conditions.
