Product details
Overview
SF63G from Taiwan Semiconductor is a 150 V, 6 A super fast recovery rectifier diode in DO-201AD package, featuring 35 ns reverse recovery time, 0.975 V forward voltage at 6 A/25°C, and 150 A surge capability - deployed in DC-DC converters and switching inverters requiring low conduction loss and rapid commutation.
For engineers reviewing the SF63G datasheet, SF63G pinout, SF63G application, or SF63G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), forward voltage consistency across temperature, junction-to-lead thermal resistance (5 °C/W), and AEC-Q101 qualification availability for automotive-grade reliability validation.
Technical Context
The SF63G employs a single-die silicon PN junction optimized for super-fast recovery (trr ≤ 35 ns) with low stored charge, enabling high-frequency operation in hard-switched topologies. Its 150 V VRRM rating targets mid-voltage industrial and automotive power conversion stages where efficiency and EMI control are critical.
Thermal design is supported by a low RθJL of 5 °C/W and DO-201AD package construction with pure tin-plated leads compliant to J-STD-002. The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating ceiling in flyback or boost output rectification |
| IF | 6 A - continuous average forward current; sets baseline conduction capacity under thermal equilibrium |
| IFSM | 150 A - non-repetitive surge rating (8.3 ms half-sine); supports inrush and fault-current handling without failure |
| VF @ 6A, 25°C | 0.975 V - forward drop at rated current; directly determines conduction loss (Pcond ≈ 5.85 W) |
| trr | 35 ns - reverse recovery time; enables stable operation up to ~3 MHz switching frequencies with minimal switching loss |
| RθJL | 5 °C/W - junction-to-lead thermal resistance; allows direct heatsinking via PCB copper or clip-mounting for thermal management |
| CJ @ 1MHz, 4V | 100 pF - junction capacitance; impacts high-frequency turn-off behavior and EMI generation in snubberless designs |
Pinout & Package
DO-201AD axial-leaded package with cathode band marking; lead finish: pure tin, solderable per J-STD-002; weight ≈ 1.20 g; UL 94V-0 molding compound.
| 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 adequate trace width for 6 A RMS |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to output rail or bus; polarity must be observed to prevent catastrophic short during reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Super-fast recovery (trr ≤ 35 ns) | Enables efficient operation in 100–500 kHz SMPS without added snubbers or gate drive complexity |
| Low VF (0.975 V @ 6 A) | Reduces conduction loss by ~15% vs. standard fast rectifiers, improving system efficiency at full load |
| High IFSM (150 A) | Withstands transient overloads common in motor drives and battery-charging circuits without degradation |
| DO-201AD mechanical robustness | Supports automated insertion and wave soldering; meets JESD201 Class 2 whisker resistance for long-term reliability |
| AEC-Q101 qualified option (SF63GH) | Validated for automotive power modules and engine control units requiring zero-defect reliability |
Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling Path |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48 V–12 V buck-derived DC-DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Unidirectional current valve conducting during transformer secondary positive half-cycle; blocks reverse voltage during reset phase. Use Value: 35 ns trr minimizes reverse recovery loss and associated ringing, reducing MOSFET stress and EMI filter burden. | Use Scenario: Freewheeling path across IGBTs in 3-phase motor inverters for HVAC and industrial drives. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during IGBT turn-off; clamps inductive kickback energy. Use Value: 0.975 V VF lowers conduction loss during freewheeling intervals, improving thermal margin at 6 A continuous. |
| Automotive On-Board Charger (OBC) Auxiliary Supply | Industrial AC-DC Front-End Bridge Leg |
Use Scenario: Auxiliary 12 V supply rectification in AEC-Q101-compliant OBC modules powering control logic and gate drivers. IC Role / Device Role / Timing Role: High-reliability output rectifier subjected to wide ambient temperature swings and vibration. Use Value: AEC-Q101-qualified variant (SF63GH) ensures validated lifetime performance under automotive thermal cycling and humidity tests. | Use Scenario: Single-leg replacement in discrete bridge configurations for 24 V industrial PLC power supplies. IC Role / Device Role / Timing Role: Standalone high-current rectifier used in half-wave or center-tap configurations where integrated bridges lack voltage headroom. Use Value: 150 V VRRM provides 2× safety margin over 24 V AC input peaks (≈67 V), supporting brownout and surge resilience. |
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 (STMicroelectronics) | Same 6 A / 600 V rating but higher VF (1.15 V @ 6 A); trr = 30 ns; TO-220AC package | Higher thermal mass suits forced-air-cooled industrial supplies; not axial-leaded | Select when board space allows TO-220 mounting and higher VF is acceptable for improved trr margin |
| ES1J (ON Semiconductor) | Lower current (1 A), lower VRRM (600 V), smaller DO-41 package; VF = 0.95 V @ 1 A | Not suitable for 6 A continuous use; limited to signal-level or low-power auxiliary rails | Use only in low-current sensing or bias supply paths - not a functional substitute for SF63G's 6 A rating |
Compared with STTH6L06S and ES1J, the SF63G uniquely balances 6 A current handling, 150 V rating, axial DO-201AD form factor, and 0.975 V VF - making it optimal for cost-sensitive, high-volume industrial DC-DC and inverter freewheeling where leaded assembly and thermal resistance matter.

FAQ
What is the maximum junction temperature rating for SF63G?
The SF63G has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating allows reliable deployment in enclosed industrial enclosures and under-hood automotive environments when mounted on sufficient copper area or heatsink. Derating curves in the SF63G datasheet define allowable IF versus ambient temperature.
Is SF63G RoHS and halogen-free compliant?
Yes, SF63G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These compliance attributes are verified in TSC's G2105 revision documentation for the SF6xG series.
Does SF63G have AEC-Q101 qualification?
The base SF63G is not AEC-Q101 qualified, but its variant SF63GH is fully AEC-Q101 qualified. SF63GH shares identical electrical and thermal specifications with SF63G and adds automotive-grade stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST).
What is the reverse recovery time (trr) test condition for SF63G?
The SF63G reverse recovery time is specified as ≤35 ns under conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, measured per JEDEC standards. This value is confirmed across the full operating temperature range and supports stable operation in hard-switched topologies up to 500 kHz.
How does SF63G compare to SF64G in terms of forward voltage?
SF63G and SF64G share identical forward voltage specification: VF ≤ 0.975 V at IF = 6 A and TJ = 25°C. Both belong to the same die family optimized for low conduction loss; the only difference is VRRM - 150 V for SF63G vs. 200 V for SF64G - with no impact on VF performance at rated current.
