Product details
Overview
SFT16GHA1G from Taiwan Semiconductor is a 400 V, 1 A AEC-Q101-qualified super fast rectifier diode in TS-1 package, featuring 1.30 V forward voltage at 1 A and 35 ns reverse recovery time, used in automotive-grade DC-DC converters and freewheeling paths.
For engineers reviewing the SFT16GHA1G datasheet, SFT16GHA1G pinout, SFT16GHA1G application, or SFT16GHA1G equivalent, key selection criteria include peak reverse voltage (400 V), surge current rating (30 A), junction temperature range (–55 °C to +150 °C), thermal resistance (100 °C/W), and AEC-Q101 qualification status.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. It delivers low conduction loss via 1.30 V VF at 1 A and fast switching via 35 ns trr, enabling efficient operation in 50–500 kHz SMPS topologies.
The TS-1 package supports surface-mount assembly with pure tin-plated leads compliant with J-STD-002, and its 100 °C/W RθJA requires PCB copper area for thermal management in continuous 1 A operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/clamp circuits |
| IF | 1 A - average forward current; sets continuous power handling under derated ambient conditions |
| IFSM | 30 A - non-repetitive surge current (8.3 ms half-sine); withstands startup/inrush transients |
| VF | 1.30 V @ 1 A, 25 °C - forward drop directly impacts conduction loss and thermal load in high-duty-cycle apps |
| trr | 35 ns - reverse recovery time; enables stable operation up to ~500 kHz without excessive switching loss |
| CJ | 10 pF @ 1 MHz, 4 V - low junction capacitance minimizes capacitive coupling and EMI in high-dv/dt environments |
| TJ max | +150 °C - maximum junction temperature; allows use in under-hood automotive modules with limited airflow |
Pinout & Package
TS-1 package: surface-mount, single-anode/single-cathode configuration with cathode band marking; lead-free, RoHS-compliant, halogen-free molding compound (UL 94V-0), 0.200 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck freewheel path) |
| Cathode | Forward current exit point | Marked by band; ties to output rail or inductor return; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive power electronics per stress test requirements (HTOL, TC, HAST, etc.) |
| Super fast recovery (35 ns) | Reduces switching loss and ringing in high-frequency converters vs. standard rectifiers (>100 ns) |
| Low VF (1.30 V) | Lowers conduction loss by ~15% vs. comparable 400 V rectifiers with VF ≥ 1.5 V at 1 A |
| High IFSM/IF ratio (30×) | Supports robust transient tolerance without derating for pulsed loads like motor commutation spikes |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive 2011/65/EU for green manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.05 V VF @ 1 A, 50 ns trr, TO-277A package | Higher voltage margin but slower recovery; higher thermal resistance (125 °C/W) | Prefer when system requires >400 V blocking but can accept higher switching loss |
| ES1J-M3/84A | 600 V VRRM, 1.7 V VF @ 1 A, 35 ns trr, SMA package | Same trr but higher VF; smaller package with lower IFSM (25 A) | Choose for space-constrained designs where 400 V rating suffices and surge margin is secondary |
Compared with STTH1L06S and ES1J-M3/84A, the SFT16GHA1G offers optimal balance of 400 V rating, 1.30 V VF, 35 ns trr, and AEC-Q101 qualification-making it preferred for cost-sensitive, thermally constrained automotive and industrial 24–48 V systems.

FAQ
What is the peak repetitive reverse voltage rating of the SFT16GHA1G?
The SFT16GHA1G has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the official Taiwan Semiconductor datasheet (Version J2104). The "16" in the part number directly encodes this 400 V rating per the SFT1xG family coding scheme. Operating above this voltage risks avalanche breakdown and permanent device failure.
Is the SFT16GHA1G suitable for automotive applications?
Yes, the SFT16GHA1G is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in the part number and confirmed in the Features section of the datasheet. It undergoes stress testing including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST) to ensure reliability in automotive under-hood environments with ambient temperatures up to +125 °C and junction temperatures to +150 °C.
What is the forward voltage drop of the SFT16GHA1G at rated current?
The SFT16GHA1G exhibits a typical forward voltage (VF) of 1.30 V at 1 A forward current and 25 °C junction temperature, per the Electrical Specifications table on page 2 of the datasheet. This value is measured under pulse conditions (PW = 0.3 ms) and represents the conduction loss baseline for thermal design calculations in continuous or high-duty-cycle operation.
What package type does the SFT16GHA1G use, and what are its key mechanical attributes?
The SFT16GHA1G uses the TS-1 surface-mount package, as specified in the Mechanical Data and Ordering Information sections. Key attributes include pure tin-plated leads (J-STD-002 solderable), UL 94V-0 flammability-rated molding compound, cathode polarity marked by a band, and a typical weight of 0.200 g. The TS-1 outline dimensions are provided on page 5 of the datasheet.
How does the reverse recovery time of the SFT16GHA1G impact switching performance?
The SFT16GHA1G has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery minimizes switching loss and voltage overshoot during turn-off, enabling stable operation in high-frequency (up to ~500 kHz) switch-mode power supplies and reducing EMI generation compared to standard or fast recovery diodes with trr > 75 ns.
