Product details
Overview
SF68GHB0G from Taiwan Semiconductor is a 600 V, 6 A super fast recovery rectifier diode in DO-201AD package, featuring 1.700 V forward voltage at 6 A and 35 ns reverse recovery time, designed for high-efficiency freewheeling and switching-mode power conversion in automotive-grade systems.
For engineers reviewing the SF68GHB0G datasheet, SF68GHB0G pinout, SF68GHB0G application, or SF68GHB0G equivalent, key selection criteria include peak reverse voltage (600 V), surge current rating (150 A), junction-to-lead thermal resistance (5 °C/W), AEC-Q101 qualification, and low-junction-capacitance (50 pF) for high-frequency switching integrity.
Technical Context
This device operates as a single-die, unidirectional super fast rectifier with optimized carrier lifetime control to achieve 35 ns trr while maintaining low VF and high surge robustness. Its 600 V VRRM and 150 A IFSM support high-voltage DC-DC stages and motor drive freewheel paths under transient stress.
The DO-201AD package delivers 5 °C/W RθJL and meets UL 94V-0 flammability, JESD201 Class 2 whisker resistance, and pure tin plating per J-STD-002 - enabling reliable reflow and wave soldering in automotive and industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports primary-side rectification in 400 V AC-input SMPS and 48 V–60 V battery-fed inverters |
| IF | 6 A continuous - rated for sustained conduction in 100–200 W power stages without derating below 75°C ambient |
| IFSM | 150 A (8.3 ms half-sine) - withstands inrush and short-circuit currents in motor drives and UPS hold-up circuits |
| VF @ 6 A | 1.700 V - enables <10.2 W conduction loss at full load, critical for thermal management in sealed enclosures |
| trr | 35 ns - minimizes switching losses and EMI in >100 kHz converters, especially with SiC/GaN FETs |
| CJ | 50 pF @ 4 V - reduces capacitive coupling noise and improves dv/dt immunity in high-side switch node placement |
| RθJL | 5 °C/W - allows direct PCB copper pour heatsinking without clip or thermal pad, simplifying layout |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin-plated and solderable per J-STD-002; polarity indicated by single black band on cathode end.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6R06DJF | 600 V, 6 A, trr = 30 ns, VF = 1.75 V @ 6 A, TO-220AC package | Higher thermal mass but requires mounting hardware; no AEC-Q101 qualification | Preferred where board space permits and mechanical mounting is acceptable; not suitable for automotive under-hood use |
| ON Semi MUR660CT | 600 V, 6 A dual common-cathode, trr = 50 ns, VF = 1.85 V @ 6 A, TO-220AB | Dual configuration enables half-wave bridge; slower recovery increases switching loss in >100 kHz designs | Used when dual-diode topology is needed; avoid in high-frequency SMPS due to higher trr and VF |
Compared with STTH6R06DJF and MUR660CT, SF68GHB0G offers AEC-Q101 compliance, DO-201AD's compact axial footprint, and superior trr/VF trade-off - making it optimal for space-constrained, automotive-qualified, high-frequency freewheeling roles.

FAQ
What is the peak repetitive reverse voltage rating of SF68GHB0G?
The SF68GHB0G has a peak repetitive reverse voltage (VRRM) rating of 600 V, verified per the manufacturer's absolute maximum ratings table. This rating defines the maximum reverse-biased voltage the device can block continuously without breakdown, and is confirmed for SF68GHB0G in the SF61G–SF68G family datasheet revision G2105. The 600 V value corresponds to the "68" in the part number and is validated under standard test conditions (TA = 25°C).
Is SF68GHB0G qualified to AEC-Q101 standards?
Yes, SF68GHB0G is AEC-Q101 qualified, as indicated by the "H" suffix in the ordering code and explicitly stated in the FEATURES section of the official datasheet. The "H" denotes AEC-Q101 qualification, and the device undergoes full stress testing including HTOL, temperature cycling, and unbiased HAST per the AEC-Q101-005 standard. This makes SF68GHB0G suitable for automotive powertrain and body electronics applications.
What is the forward voltage drop of SF68GHB0G at 6 A and 25°C?
The forward voltage (VF) of SF68GHB0G is 1.700 V at IF = 6 A and TJ = 25°C, per the ELECTRICAL SPECIFICATIONS table. This value is measured under pulse test conditions (PW = 0.3 ms) and represents the typical conduction loss under nominal operating current. At elevated junction temperatures (e.g., 125°C), VF decreases slightly due to semiconductor physics, but the datasheet specifies only the 25°C value as typ/max.
What package type does SF68GHB0G use, and what are its key mechanical properties?
SF68GHB0G uses the DO-201AD axial-leaded package, confirmed in MECHANICAL DATA and PACKAGE OUTLINE DIMENSIONS sections. Key properties include UL 94V-0 flammability-rated molding compound, pure tin-plated leads compliant with J-STD-002, JESD201 Class 2 whisker resistance, and cathode polarity marked by a single black band. The device weighs approximately 1.20 g.
What is the reverse recovery time (trr) specification for SF68GHB0G?
The reverse recovery time (trr) of SF68GHB0G is 35 ns maximum, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the ELECTRICAL SPECIFICATIONS table. This parameter reflects the speed at which the diode transitions from conduction to blocking state and is critical for minimizing switching losses in high-frequency converters. The 35 ns value applies to the entire SF67G–SF68G subgroup.
