Product details
Overview
SF67GHA0G from Taiwan Semiconductor is a 500V, 6A super fast recovery rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 1.700V forward voltage at 6A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC-DC converters requiring low conduction loss and fast switching.
For engineers reviewing the SF67GHA0G datasheet, SF67GHA0G pinout, SF67GHA0G application, or SF67GHA0G equivalent, key selection criteria include its 500V VRRM, 150A IFSM, 5°C/W RθJL, junction capacitance of 50pF, and AEC-Q101 qualification status - all critical for automotive power supply and industrial SMPS design.
Technical Context
This discrete silicon rectifier uses a single-die planar structure optimized for super-fast recovery (trr ≤ 35ns), enabling efficient operation in 100–500kHz switching topologies. Its low Qrr and controlled soft-recovery behavior minimize EMI and switching losses during freewheeling and flyback transitions.
The device operates across –55°C to +150°C junction temperature range with 5°C/W junction-to-lead thermal resistance, supporting high-power density designs where thermal management is constrained. Pure tin-plated leads ensure J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - Maximum repetitive reverse voltage; defines safe blocking capability in 400V DC bus applications |
| IF | 6 A - Continuous average forward current; supports 75W–100W output stages without forced air |
| trr | 35 ns - Reverse recovery time; enables stable operation up to 500kHz with minimal switching loss |
| VF | 1.700 V @ 6A, 25°C - Forward voltage drop; determines conduction loss (10.2W at full load) |
| CJ | 50 pF @ 4V - Junction capacitance; impacts high-frequency ringing and snubber sizing |
| RθJL | 5 °C/W - Junction-to-lead thermal resistance; allows direct heatsinking via PCB copper pour or lead frame |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; body length 9.5mm, diameter 3.6mm, lead spacing 5.0mm; RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to lower-potential node (e.g., transformer secondary center-tap or switch node) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail; polarity marking prevents incorrect PCB placement |
Key Features
| Feature | Design Value |
|---|---|

| Super fast recovery (trr ≤ 35ns) | Reduces switching loss and EMI in high-frequency SMPS vs. standard fast rectifiers (≥75ns) |
| Low VF = 1.700V @ 6A | Minimizes conduction loss in 12V–48V output rails, improving efficiency by ~0.8% over 1.85V alternatives |
| High IFSM = 150A | Withstands 8.3ms surge events (e.g., cold-start inverter inrush) without degradation |
| DO-201AD mechanical robustness | Meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability for under-hood use |

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 VRRM (600V), slightly higher VF (1.75V), trr = 30ns, TO-220AC package | Requires heatsink mounting; not AEC-Q101 qualified | Preferred for non-automotive 600V systems needing lowest trr; unsuitable for space-constrained DO-201AD layouts |
| VS-6EWH05FN-M3 (Vishay) | 500V VRRM, 6A IF, trr = 35ns, same DO-201AD, AEC-Q101 qualified | Identical electrical specs and qualification; different marking and traceability chain | Drop-in alternative with identical form, fit, and function; verified for automotive infotainment power rails |
Compared with STTH6S06D, SF67GHA0G offers smaller footprint and automotive qualification but requires tighter layout for thermal dissipation; versus VS-6EWH05FN-M3, it delivers equivalent performance with Taiwan Semiconductor's supply chain continuity and green compound compliance.

FAQ
What is the peak repetitive reverse voltage rating of SF67GHA0G?
The SF67GHA0G has a peak repetitive reverse voltage (VRRM) rating of 500 V, confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version G2105). This rating defines the maximum DC or sinusoidal AC reverse voltage the device can block continuously without breakdown, making it suitable for 400V nominal bus applications with 25% safety margin.
Is SF67GHA0G AEC-Q101 qualified, and what does the 'H' suffix indicate?
Yes, SF67GHA0G is AEC-Q101 qualified - the 'H' in the ordering code explicitly denotes AEC-Q101 qualification per the TSC Ordering Information table. This means SF67GHA0G has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing, validating its suitability for automotive power electronics.
What is the forward voltage drop of SF67GHA0G at rated current?
The forward voltage (VF) of SF67GHA0G is 1.700 V at 6 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value increases with temperature and current; at 125°C and 6A, typical VF rises to approximately 1.45V due to negative temperature coefficient behavior of silicon PN junctions.
Does SF67GHA0G have a defined reverse recovery time, and how is it measured?
Yes, SF67GHA0G has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the Electrical Specifications table. This parameter reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss and EMI in high-frequency converters.
What package type and lead finish does SF67GHA0G use?
SF67GHA0G uses the DO-201AD axial-leaded package with pure tin-plated leads, compliant with J-STD-002 for solderability and JESD201 Class 2 for whisker resistance. The cathode is marked by a visible band, and the molding compound is halogen-free and UL 94V-0 rated, as documented in the Mechanical Data section.
