Product details
Overview
SF63G from Taiwan Semiconductor is a 150V, 6A super fast recovery 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 DC-DC converters and switching inverters for high-efficiency power conversion.
For engineers reviewing the SF63G datasheet, SF63G pinout, SF63G application, or SF63G equivalent, key selection criteria include VRRM = 150V, IF = 6A, trr = 35ns, VF = 0.975V, and DO-201AD thermal performance (RθJL = 5°C/W).
Technical Context
This single-die, axial-leaded super fast rectifier operates with low conduction loss and rapid charge removal, enabled by optimized epitaxial structure and controlled lifetime control. Its 35ns trr and 100pF junction capacitance support high-frequency switching up to several hundred kHz.
The device sustains repetitive 150V reverse blocking while delivering 6A average forward current at ≤150°C junction temperature, with thermal resistance RθJA = 40°C/W enabling compact heatsink-free designs in moderate-power applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum non-repetitive reverse voltage the diode blocks reliably in circuit |
| IF | 6 A - Continuous average forward current rating at TA = 75°C with adequate PCB copper |
| trr | 35 ns - Reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables <500 kHz switching |
| VF | 0.975 V @ 6A, 25°C - Low conduction loss reduces power dissipation in high-current paths |
| IFSM | 150 A - Peak non-repetitive surge current (8.3ms half-sine) for inrush/load-dump tolerance |
| RθJL | 5 °C/W - Junction-to-lead thermal resistance supports direct lead soldering into thermally robust layouts |
| CJ | 100 pF @ 1MHz, 4V - Low junction capacitance minimizes switching node ringing and EMI |
Pinout & Package
DO-201AD package: axial-leaded, molded epoxy case with cathode band marking; leads are pure tin-plated, J-STD-002 solderable; weight ≈1.20g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Forward current entry point | Connected to lower-potential side (e.g., switch node or ground return) in freewheeling path |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail; polarity marking ensures correct orientation in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35 ns) | Enables high-frequency SMPS operation with reduced switching loss and EMI vs. standard rectifiers |
| Low VF (0.975 V @ 6A) | Minimizes conduction loss in 6A continuous paths, improving efficiency in 12–48V DC-DC stages |
| High IFSM (150 A) | Withstands transient overcurrents without failure during startup, short-circuit, or load dump events |
| DO-201AD with UL 94V-0 molding | Provides mechanical robustness and flame-retardant reliability in industrial and automotive-qualified assemblies |
| AEC-Q101 qualified option (SF63GH) | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock stress |
Applications
| DC-DC Converters | Switching Inverters |
|---|---|
Use Scenario: Secondary-side rectification in isolated 24V–48V input buck-derived DC-DC modules for telecom and industrial PLCs. IC Role / Device Role / Timing Role: Freewheeling diode conducting during low-side switch off-time to maintain inductor current continuity. Use Value: 35ns trr and 0.975V VF reduce switching loss and thermal rise, enabling >92% efficiency at 200 kHz. | Use Scenario: Output stage anti-parallel diode in half-bridge motor drive inverters for HVAC blowers and pump controllers. IC Role / Device Role / Timing Role: Bidirectional current path for inductive kickback energy recovery during PWM dead-time. Use Value: 150A IFSM handles motor stall surges; 150V VRRM matches 100V bus derating requirements. |
| Freewheeling Diodes | Power Factor Correction |
Use Scenario: Inductor flyback path in synchronous buck regulators powering FPGA core rails or ASIC SoCs. IC Role / Device Role / Timing Role: Uncontrolled rectifier providing low-loss current recirculation when high-side MOSFET is off. Use Value: 100pF CJ limits capacitive coupling noise into sensitive analog/digital domains on shared PCBs. | Use Scenario: Boost diode in active PFC front-end stages for LED drivers and industrial AC-DC supplies. IC Role / Device Role / Timing Role: High-voltage output rectifier handling 150–200V DC link with fast turn-off to minimize boost switch overlap loss. Use Value: 35ns trr prevents reverse recovery current from overlapping with MOSFET turn-on, reducing shoot-through risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D (STMicroelectronics) | VRRM = 600V, trr = 35ns, VF = 1.15V @ 6A - higher voltage rating but higher VF | Used where 600V isolation or universal input AC-DC is required; less efficient at 150V-class systems | Select SF63G when VRRM = 150V suffices and lowest conduction loss is prioritized |
| ES6D (ON Semiconductor) | VRRM = 200V, trr = 35ns, VF = 0.92V @ 6A - slightly lower VF, same speed, 50V higher VRRM | Common in 24V/48V telecom rectifiers; marginally better surge margin than SF63G | Choose ES6D if 200V rating is needed for design headroom or legacy board reuse |
Compared with STTH6L06D and ES6D, the SF63G delivers optimal balance of low VF, precise 150V rating, and proven DO-201AD manufacturability - making it preferred for cost-sensitive, thermally constrained 150V-rated power stages.

FAQ
What is the maximum junction temperature rating for SF63G?
The SF63G has a maximum junction temperature (TJ) of +150°C, with operational storage range from –55°C to +150°C. This rating allows reliable operation in enclosed industrial enclosures or under-hood automotive environments when mounted on sufficient copper area or heatsink. Thermal derating begins above 75°C ambient per the forward current derating curve in the SF63G datasheet.
Is SF63G RoHS and halogen-free compliant?
Yes, SF63G is RoHS compliant and halogen-free per IEC 61249-2-21. The DO-201AD molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes are confirmed in Taiwan Semiconductor's G2105 revision documentation for the SF6xG family.
Does SF63G have AEC-Q101 qualification?
The base SF63G is not AEC-Q101 qualified; however, the variant SF63GH is fully AEC-Q101 qualified and shares identical electrical and thermal specifications. SF63GH adds automotive-grade screening including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - critical for automotive power modules and body control units.
What is the reverse recovery time test condition for SF63G?
The SF63G reverse recovery time (trr) is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per JEDEC-standard test circuit shown in Figure 6 of the SF6xG datasheet. This 35ns value is guaranteed maximum and applies across the full operating temperature range, supporting stable high-frequency switching behavior.
Can SF63G replace SF62G or SF64G in an existing design?
SF63G can replace SF62G (100V) only if 150V VRRM margin is acceptable; it cannot safely replace SF64G (200V) in 200V-rated circuits due to insufficient reverse voltage rating. All SF6xG devices share identical DO-201AD package, pinout, and thermal characteristics - so mechanical layout remains unchanged, but voltage derating must be re-verified per application stress conditions.
