Product details
Overview
SF64GH from Taiwan Semiconductor is a 200V, 6A AEC-Q101-qualified super fast rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 0.975V forward voltage at 6A/25°C, and 150A surge capability - deployed in automotive DC-DC converters and industrial switching inverters.
For engineers reviewing the SF64GH datasheet, SF64GH pinout, SF64GH application, or SF64GH equivalent, key selection criteria include VRRM = 200V, IF = 6A, trr = 35ns, AEC-Q101 qualification status, and DO-201AD thermal performance (RθJL = 5°C/W).
Technical Context
This single-die silicon rectifier operates with ultra-fast recovery (trr ≤ 35ns) under 0.5A forward / 1.0A reverse test conditions, enabling high-frequency switching in SMPS topologies. Its low VF (0.975V typ. @ 6A, 25°C) and low CJ (100pF @ 1MHz, 4V) reduce conduction and capacitive losses.
The device sustains repetitive reverse voltages up to 200V (VRRM) and handles non-repetitive surge currents of 150A (8.3ms half-sine), with junction temperature rated from –55°C to +150°C and RθJA = 40°C/W for ambient-limited designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling circuits |
| IF | 6 A - Continuous average forward current; determines heatsink sizing and PCB copper area requirements |
| trr | 35 ns - Reverse recovery time; enables operation up to ~3 MHz switching frequency without excessive switching loss |
| VF | 0.975 V (typ.) @ 6A, 25°C - Low conduction loss; reduces power dissipation by ~1.2W vs. standard FR diodes at same current |
| CJ | 100 pF @ 1MHz, 4V - Junction capacitance; impacts EMI generation and snubber design in high-dv/dt applications |
| RθJL | 5 °C/W - Junction-to-lead thermal resistance; supports direct lead soldering to copper planes for enhanced thermal transfer |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; leads are pure tin-plated, J-STD-002 solderable, and meet JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires thermal relief on PCB pad |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); polarity must be verified before placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications per stress test requirements (HTOL, TC, H3TRB, etc.) |
| Super fast recovery (trr ≤ 35ns) | Enables >500 kHz switching in PFC and LLC stages without significant reverse recovery loss |
| Low VF (0.975V typ.) | Reduces steady-state conduction loss by ~25% versus standard fast recovery diodes at 6A |
| RoHS & halogen-free | Complies with IEC 61249-2-21; suitable for consumer, industrial, and automotive end-equipment compliance programs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06S | VRRM = 600V, trr = 35ns, VF = 1.15V @ 6A - higher voltage rating but 18% higher VF | Preferred where system overvoltage transients exceed 200V; less efficient at 12–48V bus levels | Select when VRRM margin >300V required; not drop-in due to higher VF and different thermal profile |
| ON Semi MUR620CT | Dual common-cathode configuration, VRRM = 200V, trr = 35ns, VF = 0.92V - lower VF but dual-die layout increases footprint | Used in dual-phase or interleaved rectification; requires PCB redesign for single-diode replacement | Choose only if dual-diode topology is already implemented; not pin-compatible with SF64GH's single DO-201AD form factor |
Compared with STTH6L06S and MUR620CT, SF64GH offers optimal balance of 200V rating, 0.975V VF, AEC-Q101 qualification, and compact DO-201AD packaging - making it the preferred choice for space-constrained, automotive-grade 6A rectification where exact VRRM match and qualification are mandatory.

FAQ
What is the peak repetitive reverse voltage rating for SF64GH?
The SF64GH has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version G2105), and defines the maximum reverse-bias voltage the device can block continuously without breakdown. It is critical for selecting appropriate voltage derating margins in circuit design.
Is SF64GH AEC-Q101 qualified, and what does the "H" suffix indicate?
Yes, SF64GH is AEC-Q101 qualified - the "H" suffix explicitly denotes qualification per the AEC-Q101 stress test standard for discrete semiconductors. This includes HTOL, temperature cycling, H3TRB, and mechanical shock testing. The qualification applies to the specific SF64GH variant, not the entire SF6xG family, and is documented in Taiwan Semiconductor's product change notice G2105.
What is the typical forward voltage of SF64GH at 6A and 25°C?
The typical forward voltage (VF) of SF64GH is 0.975 V at IF = 6 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects low conduction loss essential for high-efficiency power conversion. Maximum VF is not specified; only typical is provided.
Does SF64GH have a specified reverse recovery time, and under what test conditions?
Yes, SF64GH has a maximum reverse recovery time (trr) of 35 ns. This is measured under the condition: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. The test circuit and waveform are illustrated in Figure 6 of the datasheet, confirming its suitability for high-frequency switching applications.
What package type and marking does SF64GH use?
SF64GH uses the DO-201AD axial-leaded package with cathode polarity indicated by a visible band. The device marking reads "SF64G" followed by date code and factory identifier (e.g., "SF64G YWW F"). Lead finish is pure tin, compliant with J-STD-002 for reliable solderability, and the molding compound meets UL 94V-0 flammability rating.
