Product details
Overview
SFT11GHR0G from Taiwan Semiconductor is a 1 A, 50 V super fast 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 current capability; used in DC-DC converters and freewheeling paths where low conduction loss and fast switching are required.
For engineers reviewing the SFT11GHR0G datasheet, SFT11GHR0G pinout, SFT11GHR0G application, or SFT11GHR0G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), thermal resistance (100 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status.
Technical Context
This device is a single-die, planar epitaxial super fast recovery rectifier optimized for high-efficiency switching power supplies. Its 35 ns trr and low VF enable reduced switching losses and improved system efficiency in high-frequency operation.
The TS-1 package provides surface-mount compatibility with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band; device weight is approximately 0.200 g.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling circuits |
| IF | 1 A - average forward current rating at TA = 25°C; determines continuous conduction capacity |
| IFSM | 30 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload handling |
| trr | 35 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching frequency use |
| VF | 0.95 V - forward voltage at IF = 1 A, TJ = 25°C; directly impacts conduction loss and thermal rise |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance; informs heatsinking requirements on standard FR-4 PCB |
| TJ max | +150 °C - maximum junction temperature; sets upper thermal boundary for reliability under 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 |
|---|---|---|---|
| STTH1R06U | VRRM = 600 V, VF = 1.15 V @ 1 A, trr = 30 ns, TO-277A package | Higher voltage rating suits universal-input PFC stages; not drop-in due to different footprint and higher VF | Select when >100 V reverse blocking is needed; verify layout compatibility and thermal margin |
| ON APT10S20B | VRRM = 200 V, VF = 0.92 V @ 1 A, trr = 35 ns, SOD-123FL package | Same trr and lower VF, but rated for only 1 A average in SOD-123FL; derated thermal performance | Acceptable for space-constrained designs with <0.5 A continuous load; requires thermal validation |
Compared with STTH1R06U and APT10S20B, the SFT11GHR0G offers optimal balance of 50 V VRRM, 0.95 V VF, and TS-1 thermal robustness for cost-sensitive 12–24 V DC-DC outputs-without over-specifying voltage or compromising solderability.

FAQ
What is the maximum junction temperature rating for SFT11GHR0G?
The SFT11GHR0G has a maximum junction temperature (TJ max) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This rating allows reliable operation in under-hood automotive environments and enclosed industrial enclosures. Derating curves confirm usable current capacity down to –55 °C ambient. The SFT11GHR0G must be mounted on PCB copper areas sufficient to maintain TJ ≤ 150 °C under worst-case load.
Is SFT11GHR0G AEC-Q101 qualified?
Yes, SFT11GHR0G is AEC-Q101 qualified, as confirmed by the "H" suffix in the ordering code and explicit listing in Taiwan Semiconductor's qualification documentation. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge. The SFT11GHR0G is approved for use in automotive powertrain and body electronics where component-level reliability is mandated.
What does the "R0G" suffix mean in SFT11GHR0G?
The "R0G" suffix in SFT11GHR0G indicates tape-and-reel packaging: "R" denotes reel, "0" is a placeholder, and "G" signifies green (halogen-free) molding compound per IEC 61249-2-21. This matches Taiwan Semiconductor's ordering convention where SFT11GHR0G = TS-1 package, AEC-Q101 qualified ("H"), green compound ("G"), and 5,000 pcs/reel ("R0"). The SFT11GHR0G is not a variant with altered electrical specs.
What is the reverse recovery time (trr) of SFT11GHR0G and how is it measured?
The SFT11GHR0G has a reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the official datasheet test condition. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency converters. The SFT11GHR0G's trr remains stable across its –55 to +150 °C operating range, supporting consistent performance in variable-temperature applications.
Can SFT11GHR0G replace a standard fast recovery diode like FR107?
The SFT11GHR0G can replace FR107 in 1 A, ≤50 V applications where faster recovery and lower VF are beneficial-but not as a blind drop-in. FR107 has VRRM = 1000 V and trr ≈ 500 ns; the SFT11GHR0G offers superior speed (35 ns) and efficiency (0.95 V VF) at much lower voltage rating. System-level validation of voltage margin and EMI is required before substituting the SFT11GHR0G for FR107 in legacy designs.
