Product details
Overview
SF2L6GHA0G from Taiwan Semiconductor is a 2 A, 400 V super fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 2 A and 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.
For engineers reviewing the SF2L6GHA0G datasheet, SF2L6GHA0G pinout, SF2L6GHA0G application, or SF2L6GHA0G equivalent, key selection criteria include its 400 V repetitive peak reverse voltage, 50 A surge capability, glass-passivated junction, RoHS/halogen-free compliance, and AEC-Q101 qualification status.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-efficiency DC–DC conversion and switching-mode power supplies. Its 35 ns trr enables operation at frequencies up to several hundred kHz while maintaining low switching losses.
The SF2L6GHA0G uses a glass-passivated junction for enhanced moisture resistance and long-term reliability under thermal cycling. With RθJL = 17°C/W and RθJA = 65°C/W, it supports continuous 2 A conduction at ambient temperatures up to 85°C with standard PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback or boost output stages |
| IF | 2 A - Continuous average forward current rating; determines heatsink or trace sizing in steady-state operation |
| IFSM | 50 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overload events |
| VF max | 1.30 V @ 2 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design in high-duty-cycle applications |
| trr | 35 ns - Reverse recovery time; enables efficient operation in SMPS above 100 kHz with reduced switching loss |
| Junction temp | −55°C to +150°C - Operating temperature range supports under-hood automotive and industrial environments |
| CJ | 20 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency noise coupling and snubber design requirements |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode indicated by a band. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to lower-potential node (e.g., switch node in flyback, ground in freewheeling path) |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential node (e.g., output rail, VIN in buck freewheeling) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive powertrain and body electronics per stress test requirements including HTOL, TCT, and ESD |
| Glass-passivated junction | Eliminates risk of corrosion-induced leakage or premature failure in humid or chemically aggressive environments |
| Low VF and trr | Reduces both conduction and switching losses simultaneously-critical for >90% efficiency targets in compact adapters |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for environmentally regulated end equipment |
| DO-204AC mechanical robustness | UL 94V-0 molding compound and 0.400 g mass support vibration resistance and automated assembly reliability |
Applications
| DC–DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Used in secondary-side synchronous or non-synchronous rectification of isolated DC–DC converters (e.g., 12 V → 3.3 V telecom supply). IC Role / Device Role / Timing Role: Unidirectional power switch conducting during positive half-cycle; blocks reverse voltage during off-time. Use Value: 35 ns trr minimizes reverse recovery charge loss, enabling >200 kHz operation without excessive heating. | Use Scenario: Placed across inductive loads (e.g., motor windings or solenoids) in H-bridge inverters to clamp inductive kickback. IC Role / Device Role / Timing Role: Freewheeling diode providing low-impedance return path when main switches turn off. Use Value: 50 A IFSM safely absorbs energy from 2 A inductive loads with L/R time constants up to 100 µs. |
| Automotive LED Driver Supply | Industrial AC–DC Adapter Secondary Side |
Use Scenario: Rectifies transformer output in constant-current LED drivers for headlamps or interior lighting. IC Role / Device Role / Timing Role: Output rectifier converting high-frequency AC from transformer secondary into DC bus for current regulation. Use Value: AEC-Q101 qualification ensures stable performance over −40°C to +125°C ambient, meeting ISO 16750-4 requirements. | Use Scenario: Final-stage rectifier in universal-input 100–240 VAC offline adapters delivering 5–24 VDC to embedded systems. IC Role / Device Role / Timing Role: Main output rectifier handling full load current in flyback or forward converter topologies. Use Value: 1.30 V VF max reduces conduction loss by ~15% vs. standard FR107, improving thermal margin at full load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | Same 2 A / 400 V rating; 30 ns trr, 1.35 V VF max; TO-220AC package | Requires PCB footprint change and heatsinking; not AEC-Q101 qualified | Select when higher surge rating (80 A) or forced-air cooling is needed; not suitable for space-constrained automotive modules |
| ON Semi MUR240 | 2 A / 400 V; 50 ns trr, 1.25 V VF max; DO-204AC package; no AEC-Q101 | Compatible footprint but lacks automotive qualification and has slower recovery | Acceptable for industrial adapters where AEC-Q101 is not mandated; verify trr impact on EMI in high-frequency designs |
Compared with STTH2R04 and MUR240, the SF2L6GHA0G uniquely combines DO-204AC form factor, AEC-Q101 qualification, and 35 ns recovery-making it the only drop-in solution for automotive-compliant, space-limited 400 V rectification without layout or qualification revalidation.

FAQ
What does the "H" and "A0G" suffix mean in SF2L6GHA0G?
The "H" indicates AEC-Q101 qualification, confirming the SF2L6GHA0G meets automotive reliability stress testing standards. The "A0G" denotes packaging in 1,500-unit ammo boxes with green compound (halogen-free) and standard date/lot coding. This distinguishes it from tape-and-reel variants like SF2L6GH.
Is SF2L6GHA0G pin-compatible with SF2L6G or SF2L6GH?
Yes-SF2L6GHA0G shares identical DO-204AC (DO-15) package dimensions, anode/cathode polarity marking, and electrical pinout with SF2L6G and SF2L6GH. All three use the same die and mechanical construction; only packaging format and qualification level differ.
What is the maximum junction temperature derating for SF2L6GHA0G at 2 A continuous current?
At 2 A DC, the SF2L6GHA0G reaches thermal equilibrium at approximately 125°C junction temperature with 1 cm² of 2 oz copper on FR-4, based on RθJA = 65°C/W. Derating begins above 85°C ambient; full 2 A rating is valid only up to 85°C ambient with adequate PCB copper area.
Does SF2L6GHA0G support reflow soldering, and what profile is recommended?
Yes-the pure tin-plated leads of SF2L6GHA0G comply with J-STD-002 and support lead-free reflow. Use a standard IPC/JEDEC J-STD-020 profile with peak temperature ≤ 260°C, 60–90 s above 217°C, and ramp rate ≤ 3°C/s. Avoid exceeding 10 s above 260°C to prevent molding compound degradation.
How does the 35 ns reverse recovery time of SF2L6GHA0G compare to standard fast rectifiers in the same package?
Standard fast rectifiers like 1N4937 specify trr ≥ 250 ns; even upgraded FR107 types are rated ≥ 150 ns. At 35 ns, the SF2L6GHA0G delivers >4× faster recovery, reducing switching loss and EMI generation-especially critical in 200–500 kHz SMPS designs where diode recovery dominates loss budget.
