Product details
Overview
SFT13GHA1G from Taiwan Semiconductor is a 150 V, 1 A super fast recovery rectifier diode in TS-1 package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A/25°C, and 30 A surge capability-used in DC-DC converters and freewheeling paths in automotive power supplies.
For engineers reviewing the SFT13GHA1G datasheet, SFT13GHA1G pinout, SFT13GHA1G application, or SFT13GHA1G equivalent, key selection criteria include VRRM = 150 V, IF = 1 A, trr = 35 ns, VF = 0.95 V, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The SFT13GHA1G is a single-die, planar junction super fast rectifier optimized for high-frequency switching applications. Its 35 ns reverse recovery time and low 0.95 V forward voltage at 1 A reduce conduction and switching losses in SMPS topologies.
Designed for automotive environments, it meets AEC-Q101 stress test requirements and operates across –55°C to +150°C junction temperature range, with 100°C/W junction-to-ambient thermal resistance in the TS-1 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling clamping |
| IF | 1 A continuous - average forward current rating at TA = 75°C; determines steady-state power handling |
| trr | 35 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching in resonant converters |
| VF | 0.95 V @ 1 A, 25°C - low conduction loss improves efficiency in high-duty-cycle DC-DC stages |
| IFSM | 30 A @ 8.3 ms half-sine - supports inrush and transient overload without failure |
| Junction temp | –55°C to +150°C - validated for under-hood automotive use with no derating below 125°C ambient |
Pinout & Package
TS-1 package: molded epoxy case with pure tin-plated leads, polarity indicated by cathode band, weight ≈ 0.200 g, UL 94V-0 rated compound.
| 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 / reverse blocking terminal | Connected to output rail; blocks reverse voltage up to 150 V during off-state |
Key Features
| Feature | Design Value |
|---|---|

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 | VRRM = 600 V, trr = 35 ns, VF = 1.05 V @ 1 A - higher voltage rating, same speed, slightly higher VF | Preferred where system transients exceed 200 V or multi-rail designs require common BOM across 12 V/24 V/48 V outputs | Select when higher VRRM margin is required; not drop-in due to different marking and minor VF increase |
| ES1D-E3/57T | VRRM = 200 V, trr = 35 ns, VF = 0.93 V @ 1 A - identical speed, lower VF, higher VRRM, same TS-1 footprint | Better suited for universal-input offline adapters where 200 V VRRM provides safety margin above 170 Vpk line | Direct physical replacement in TS-1 layout; verify system-level VR derating before substitution |
Compared with STTH1L06S and ES1D-E3/57T, the SFT13GHA1G offers optimal balance of 150 V rating, AEC-Q101 qualification, and 0.95 V VF for cost-sensitive automotive DC-DCs-where ES1D-E3/57T matches pinout but lacks automotive qualification, and STTH1L06S trades voltage headroom for non-automotive status.

FAQ
What is the maximum junction temperature rating for the SFT13GHA1G?
The SFT13GHA1G has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating is validated per AEC-Q101 requirements and supports sustained operation in under-hood automotive environments where ambient temperatures reach 125°C. The SFT13GHA1G maintains full electrical performance within this range without derating until TA exceeds 75°C.
Is the SFT13GHA1G pin-compatible with other TS-1 rectifiers like ES1D or STTH1R06?
Yes-the SFT13GHA1G uses the standard TS-1 package with anode and cathode terminals in identical physical locations to ES1D and STTH1R06. However, while mechanical fit is guaranteed, electrical differences exist: SFT13GHA1G has VRRM = 150 V (vs. 200 V for ES1D, 600 V for STTH1R06), and only SFT13GHA1G carries AEC-Q101 qualification. System-level validation is required before substitution.
What does the 'H' suffix in SFT13GHA1G signify?
The 'H' in SFT13GHA1G indicates AEC-Q101 qualification-confirmed by Taiwan Semiconductor's compliance documentation (Version J2104). This means the SFT13GHA1G has passed accelerated stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST), making it suitable for automotive power electronics where reliability is critical.
How is reverse recovery time (trr) measured for the SFT13GHA1G?
The SFT13GHA1G reverse recovery time of 35 ns is measured under standardized conditions: IF = 0.5 A forward bias, IR = 1.0 A reverse step, Irr = 0.25 A peak reverse recovery current, using a half-sine waveform test circuit per JEDEC JESD24-11. This value is typical and applies across the full –55°C to +125°C operating range, supporting design of >500 kHz switching converters.
Does the SFT13GHA1G meet RoHS and halogen-free requirements?
Yes-the SFT13GHA1G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are pure tin-plated to meet J-STD-002 solderability standards. These attributes are confirmed in Taiwan Semiconductor's official documentation (Version J2104) and verified through third-party material declarations.
