Product details
Overview
SF67G from Taiwan Semiconductor is a 500V, 6A super fast recovery rectifier diode in DO-201AD package, featuring 1.700 V forward voltage at 6 A and 35 ns reverse recovery time. It serves as a freewheeling or output rectifier in high-frequency switching power supplies requiring low conduction loss and fast turn-off.
For engineers reviewing the SF67G datasheet, SF67G pinout, SF67G application, or SF67G equivalent, key selection criteria include its 500 V repetitive peak reverse voltage, 150 A surge rating, 1.700 V VF at 6 A, 50 pF junction capacitance, and AEC-Q101 qualification option (SF67GH).
Technical Context
This single-die silicon rectifier uses planar epitaxial construction to achieve super-fast recovery (trr ≤ 35 ns) with controlled minority-carrier lifetime. Its 500 V VRRM and 150 A IFSM support robust operation in DC-DC converters and inverters operating up to 100 kHz.
Thermal performance is defined by RθJL = 5 °C/W and RθJA = 40 °C/W, enabling 6 A continuous forward current with appropriate PCB copper area. The device exhibits 5 µA max reverse leakage at 25 °C and 100 µA at 125 °C under rated VR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6S06D (STMicroelectronics) | Same 600 V VRRM, 6 A IF, but VF = 1.75 V @ 6 A; trr = 30 ns; TO-220AC package | Requires PCB mount heatsink; not axial-leaded | Preferred where higher surge rating (200 A IFSM) and lower trr justify TO-220 footprint |
| ES6D (ON Semiconductor) | 500 V VRRM, 6 A IF, VF = 1.7 V @ 6 A, trr = 35 ns; DO-201AD package; no AEC-Q101 option | Identical mechanical fit and basic specs; lacks automotive qualification path | Cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with STTH6S06D and ES6D, SF67G offers identical DO-201AD form factor and 500 V/6 A rating, with unique availability of AEC-Q101-qualified version (SF67GH), making it optimal for space-constrained automotive auxiliary supplies needing qualification traceability.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SF67G?
The SF67G has a VRRM rating of 500 V, verified per Taiwan Semiconductor's G2105 datasheet. This value defines the highest instantaneous reverse voltage the device can block repeatedly without breakdown. Designers must ensure circuit peak reverse stresses remain below this limit, including margin for ringing and transients. The SF67G is part of an 8-part family spanning 50 V to 600 V, with SF67G specifically assigned to the 500 V grade.
What is the forward voltage drop (VF) of SF67G at rated current?
The SF67G exhibits a maximum forward voltage of 1.700 V at 6 A and 25 °C junction temperature, as specified in the Electrical Specifications table. This VF value directly impacts conduction loss-calculating to ~10.2 W at full load-and is measured under pulsed conditions (PW = 0.3 ms). At elevated temperatures, VF decreases slightly, improving thermal stability in sustained operation.
Does SF67G have automotive qualification?
The base SF67G is not AEC-Q101 qualified, but Taiwan Semiconductor offers the SF67GH variant-identical electrically and mechanically-which is fully AEC-Q101 qualified. The "H" suffix denotes qualification per stress test requirements for automotive power electronics. Customers requiring automotive compliance must specify SF67GH; standard SF67G is intended for industrial and commercial applications.
What is the reverse recovery time (trr) specification for SF67G?
The SF67G has a maximum reverse recovery time of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This trr value reflects its super fast recovery performance, enabling efficient operation in high-frequency switching circuits up to 100 kHz. The 35 ns figure is consistent across SF67G and SF68G, distinguishing them from lower-voltage variants (SF61G–SF64G) which show higher capacitance but similar trr.
What package type does SF67G use, and what are its key mechanical features?
SF67G uses the DO-201AD axial-leaded package, with cathode indicated by a band, pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and 1.20 g typical weight. Its RθJL is 5 °C/W and RθJA is 40 °C/W, supporting 6 A continuous current when mounted on ≥1 sq-in copper area. Polarity marking and lead finish are critical for automated assembly and long-term solder joint reliability.
