Product details
Overview
SFAF1603G from Taiwan Semiconductor is a 16A, 150V super fast rectifier diode in ITO-220AC package, featuring 0.975V forward voltage at 16A/25°C, 35ns reverse recovery time, and 130pF junction capacitance. It serves as a high-efficiency freewheeling or output rectifier in DC-DC converters and switching inverters.
For engineers reviewing the SFAF1603G datasheet, SFAF1603G pinout, SFAF1603G application, or SFAF1603G equivalent, key selection criteria include repetitive peak reverse voltage (150V), surge current capability (200A), thermal resistance (1.3°C/W), AEC-Q101 qualification status, and UL recognition (E-326243).
Technical Context
The SFAF1603G employs a glass-passivated silicon junction for enhanced reliability and moisture resistance. Its super fast recovery (trr ≤ 35ns) enables operation in high-frequency switching topologies up to several hundred kHz without excessive switching loss.
Designed for single-die configuration in ITO-220AC, it delivers low conduction loss (VF = 0.975V typ. @ 16A, 25°C) and high thermal efficiency (RθJC = 1.3°C/W), supporting continuous operation at junction temperatures up to +150°C with appropriate heatsinking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CT | 16A, 200V dual common-cathode; VF = 1.05V @ 16A; trr = 30ns; TO-220AC package | Dual configuration supports center-tapped transformer or dual-output designs; higher VRRM margin | Select when dual-diode topology or >150V blocking is required; not drop-in for single-diode footprint |
| ON Semi MUR1620CT | 16A, 200V dual common-cathode; VF = 1.1V @ 16A; trr = 35ns; TO-220AC | Same speed but higher VF increases conduction loss; RoHS-compliant but not AEC-Q101 qualified | Choose for cost-sensitive industrial use where automotive qualification is unnecessary |
Compared with STTH1602CT and MUR1620CT, the SFAF1603G offers lower forward voltage and AEC-Q101 qualification in a single-diode ITO-220AC package-making it optimal for space-constrained, thermally demanding, and automotive-grade 150V rectification tasks where dual-diode integration isn't needed.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for the SFAF1603G?
The SFAF1603G has a VRRM rating of 150 V, meaning it reliably blocks up to 150 V of reverse voltage in repetitive operation. This value is fixed per the part number suffix "03" (SFAF1601G=50V, SFAF1602G=100V, SFAF1603G=150V, etc.) and is validated per JEDEC test conditions. Exceeding this voltage risks avalanche breakdown and permanent damage to the SFAF1603G.
Does the SFAF1603G have AEC-Q101 qualification?
The base SFAF1603G is not AEC-Q101 qualified; however, the variant SFAF1603GH (with 'H' suffix) is explicitly qualified per AEC-Q101 Rev D for automotive applications. The datasheet confirms AEC-Q101 availability across the SFAF1601G–SFAF1608G series, and the 'H' ordering code denotes qualification. Always verify the full part number-including suffix-when selecting for automotive use.
What is the typical forward voltage (VF) of the SFAF1603G at rated current?
The SFAF1603G exhibits a typical forward voltage of 0.975 V at 16 A and junction temperature of 25°C, measured under pulse conditions (PW = 0.3 ms). At higher temperatures (e.g., TJ = 100°C), VF decreases slightly (~0.85 V), while conduction loss remains well-controlled due to the device's low RDS(on)-like behavior in forward conduction.
How does the thermal resistance (RθJC) of the SFAF1603G impact heatsink design?
The SFAF1603G has a junction-to-case thermal resistance of 1.3°C/W. For a 16 A load with VF ≈ 0.975 V, power dissipation is ~15.6 W; with RθJC = 1.3°C/W, the junction-to-case temperature rise is ~20.3°C. To maintain TJ ≤ 150°C at TA = 85°C, the heatsink must limit case-to-ambient rise to ≤ 44.7°C, requiring a heatsink thermal resistance of ≤ 2.9°C/W when combined with interface material losses.
Is the SFAF1603G compatible with lead-free reflow soldering processes?
Yes-the SFAF1603G features matte tin-plated leads compliant with J-STD-002 for solderability, and its ITO-220AC package uses UL 94V-0 molding compound rated for peak reflow temperatures up to 260°C. The device supports standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020), and its construction meets JEDEC MSL Level 1 requirements with unlimited floor life when stored per specification.
