Product details
Overview
SF67GHR0G from Taiwan Semiconductor is a 500V, 6A super fast recovery rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 1.7V forward voltage at 6A/25°C, and 150A surge capability - deployed in high-frequency DC-DC converters and freewheeling paths in automotive power supplies.
For engineers reviewing the SF67GHR0G datasheet, SF67GHR0G pinout, SF67GHR0G application, or SF67GHR0G equivalent, key selection criteria include VRRM = 500V, IF = 6A, trr = 35ns, VF = 1.7V (6A, 25°C), and RθJA = 40°C/W - critical for thermal management and switching loss optimization in compact SMPS designs.
Technical Context
This device operates as a single-die, unidirectional super fast rectifier with AEC-Q101 qualification available (H-suffix variant), optimized for high-frequency switching where low reverse recovery charge and tight trr tolerance reduce switching losses and EMI generation.
Its DO-201AD package delivers 5°C/W junction-to-lead thermal resistance and supports 150A non-repetitive surge current under 8.3ms half-sine waveform, enabling robust operation during transient overloads in automotive and industrial power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum repetitive reverse blocking voltage; defines safe operating range in 400–450V DC bus applications |
| IF | 6 A - continuous average forward current; sets minimum heatsink requirement for sustained conduction |
| trr | 35 ns - reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables >100 kHz switching without excessive turn-off loss |
| VF | 1.7 V @ 6A, 25°C - forward voltage drop; determines conduction loss of ~10.2 W at full load |
| IFSM | 150 A - peak non-repetitive surge current; withstands inrush and fault currents in motor drives and UPS systems |
| RθJA | 40 °C/W - junction-to-ambient thermal resistance; requires ≤25°C ambient or active cooling for 6A continuous operation |
| CJ | 50 pF @ 1 MHz, 4V - junction capacitance; limits high-frequency noise coupling and affects snubber design |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance; UL 94V-0 molding compound; weight ≈1.20 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheeling path |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); blocks 500V reverse voltage |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr ≤ 35 ns) | Reduces switching loss and EMI in >100 kHz SMPS, enabling smaller magnetics and filters |
| Low VF = 1.7 V @ 6A | Lowers conduction loss by ~15% vs. standard fast rectifiers at same current, improving efficiency in 12–48V outputs |
| High IFSM = 150 A | Survives repeated cold-start surges in automotive DC-DC modules without derating |
| AEC-Q101 qualified option (SF67GH) | Validated for automotive under-hood temperature cycling, vibration, and humidity stress per JESD47 |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing compliance |

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) | VRRM = 600V, trr = 30ns, VF = 1.75V @ 6A - slightly faster but higher VF | Better suited for 400–600V DC bus with tighter trr requirements; less optimal for low-VF-driven efficiency targets | Select when trr margin is critical and 50mV VF penalty is acceptable |
| ES6D (ON Semiconductor) | VRRM = 200V, trr = 35ns, VF = 1.15V @ 6A - lower voltage rating, significantly lower VF | Only suitable for ≤200V applications (e.g., 12V/24V secondary-side rectification); not interchangeable in 500V systems | Choose only for low-voltage, ultra-low-loss designs where VRRM headroom is not required |
Compared with STTH6S06D and ES6D, SF67GHR0G provides the optimal balance of 500V blocking, 35ns recovery, and 1.7V forward drop - making it uniquely suited for 400–450V automotive and industrial DC-DC outputs where both voltage margin and conduction efficiency matter.

FAQ
What is the maximum junction temperature rating for SF67GHR0G?
The SF67GHR0G has a maximum junction temperature (TJ) of +150°C and a storage temperature range of –55°C to +150°C. This rating allows reliable operation in under-hood automotive environments and sealed industrial enclosures when mounted on appropriate copper area or heatsink per its RθJA = 40°C/W specification. Thermal design must ensure TJ remains below 150°C under worst-case load and ambient conditions.
Is SF67GHR0G AEC-Q101 qualified?
SF67GHR0G itself is not AEC-Q101 qualified; however, the pin-compatible SF67GH variant (same DO-201AD package, identical electrical specs) is fully AEC-Q101 qualified. The "H" suffix denotes automotive qualification per JESD47 stress testing including temperature cycling, mechanical shock, and humidity bias. For automotive production, specify SF67GH instead of SF67GHR0G.
What does the "R0G" suffix in SF67GHR0G indicate?
The "R0G" suffix in SF67GHR0G is a Taiwan Semiconductor internal reel packaging code indicating tape-and-reel delivery with 1,250 units per reel and green (halogen-free) molding compound. It does not affect electrical or thermal specifications - all SF67G variants share identical VRRM, trr, VF, and package dimensions. The base device remains SF67G.
How does SF67GHR0G compare to SF66G in terms of voltage rating and use cases?
SF67GHR0G has a 500V VRRM, while SF66G is rated at 400V. This 100V difference makes SF67GHR0G suitable for 400–450V DC bus applications (e.g., automotive 48V systems with transient margin), whereas SF66G fits 300–350V rails. Both share identical trr = 35ns and VF = 1.3V (SF66G) vs. 1.7V (SF67GHR0G), so SF67GHR0G trades higher VF for enhanced voltage safety margin.
Can SF67GHR0G be used as a direct replacement for SF67G in existing PCB layouts?
Yes - SF67GHR0G uses the identical DO-201AD package, pinout, and mechanical dimensions as SF67G. The "R0G" suffix denotes packaging format only (tape-and-reel, green compound); all electrical, thermal, and mounting characteristics are unchanged. No PCB or layout modifications are required when substituting SF67GHR0G for SF67G in production or rework.
