Product details
Overview
SF1601G from Taiwan Semiconductor is a 16A, 50V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 8A/25°C, and 125A surge capability - deployed in DC-DC converters and switching inverters requiring high-efficiency freewheeling.
For engineers reviewing the SF1601G datasheet, SF1601G pinout, SF1601G application, or SF1601G equivalent, key selection criteria include VRRM = 50V, IF = 16A, trr = 35ns, RθJC = 1.5°C/W, and AEC-Q101 qualification availability (SF1601GH variant), critical for automotive-grade power conversion designs.
Technical Context
This single-die, single-anode/single-cathode super fast rectifier operates with low conduction loss (VF = 0.975V @ 8A, 25°C) and fast switching (trr = 35ns), enabling high-frequency operation in hard-switched topologies. Its 1.5°C/W junction-to-case thermal resistance supports reliable 16A continuous conduction under forced-air or heatsink-cooled conditions.
The device uses planar passivated silicon die in TO-220AB package with matte tin-plated leads (J-STD-002 compliant), rated for -55°C to +150°C junction temperature and meeting UL 94V-0 flammability and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines minimum system isolation margin in 24–48V DC-DC outputs. |
| IF | 16 A - Continuous forward current rating; supports 200W+ output stages with appropriate heatsinking. |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); handles startup inrush and transient overloads. |
| trr | 35 ns - Reverse recovery time; enables efficient operation up to ~500 kHz switching frequency without excessive switching loss. |
| VF | 0.975 V @ 8A, 25°C - Low forward drop reduces conduction loss by ~15% vs. standard fast rectifiers, improving efficiency in 12–48V systems. |
| RθJC | 1.5 °C/W - Thermal resistance from junction to case; allows ~10.7W dissipation at ΔT = 16°C rise above heatsink (e.g., 25°C ambient + 10°C sink rise). |
Pinout & Package
TO-220AB package: 3-terminal, single-diode configuration with anode (pin 1), cathode (pin 2), and electrically connected tab (pin 3, cathode-connected). Mounting torque ≤ 0.56 N·m; polarity marked on case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Lead) | Anode | Input terminal for forward conduction; connects to switching node or inductive source in freewheeling path. |
| Pin 2 (Lead) | Cathode | Output terminal; ties to output rail or ground return; carries full load current during conduction. |
| Tab (Metal surface) | Cathode (internally bonded) | Primary thermal path to heatsink; electrically identical to Pin 2 - requires insulating washer if mounted to grounded chassis. |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr) | 35 ns - Minimizes reverse recovery charge (Qrr) and associated switching loss in high-frequency SMPS. |
| Low forward voltage (VF) | 0.975 V @ 8A - Reduces power dissipation by ~1.2W vs. 1.1V alternatives at same current, easing thermal design. |
| High surge robustness | IFSM = 125A - Withstands repeated 8.3ms line-frequency surges common in industrial motor drives and UPS systems. |
| AEC-Q101 qualification option | Available as SF1601GH - Validated for automotive under-hood applications including engine control and ADAS power supplies. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1605D (STMicroelectronics) | VRRM = 50V, trr = 35ns, VF = 0.95V @ 8A - slightly lower VF, but RθJC = 2.0°C/W. | Same TO-220AC package (isolated tab); less thermally efficient in high-power density layouts. | Prefer when lowest possible VF dominates; verify heatsink interface due to higher thermal resistance. |
| VS-16EWH05FN-M3 (Vishay) | VRRM = 50V, trr = 30ns, VF = 0.99V @ 8A - faster recovery but higher VF; TO-220AC package. | Optimized for ultra-high-frequency PFC stages; marginally higher conduction loss at 16A DC. | Select for >1 MHz resonant topologies where trr reduction outweighs VF penalty. |
Compared with STTH1605D and VS-16EWH05FN-M3, SF1601G delivers best-in-class thermal performance (RθJC = 1.5°C/W) and balanced VF/trr trade-off - making it optimal for space-constrained 16A freewheeling in 200–500 kHz industrial and automotive converters.

FAQ
What is the maximum junction temperature rating for SF1601G?
The SF1601G has a maximum junction temperature (TJ) of +150°C, with operational range from -55°C to +150°C. This rating is validated per JEDEC standards and supports use in under-hood automotive environments when paired with appropriate thermal management. The SF1601G must be derated linearly above 25°C ambient per the forward current derating curve in the official datasheet.
Is SF1601G pin-compatible with other parts in the SF160xG series?
No - all SF160xG devices share the same TO-220AB package and pinout (anode, cathode, cathode-tab), but they differ only in VRRM rating (50V to 600V). SF1601G is mechanically and electrically pin-compatible with SF1602G through SF1608G, enabling drop-in replacement when voltage margin permits - however, VF and CJ vary across the series and must be re-verified for target operating conditions.
Does SF1601G meet automotive qualification standards?
The base SF1601G is not AEC-Q101 qualified; however, the SF1601GH variant - identical in all electrical and mechanical specifications except for extended reliability testing - is fully AEC-Q101 qualified. Customers requiring automotive compliance must specify SF1601GH, which undergoes stress testing for temperature cycling, humidity bias, and mechanical shock per AEC-Q101 Rev D.
What is the reverse recovery time test condition for SF1601G?
The SF1601G reverse recovery time (trr) is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per JEDEC standard JESD24-10. This condition reflects typical hard-switching behavior in boost and buck converters. The specified trr = 35ns is a maximum value; typical units measure ~28–32ns under these conditions.
How does the thermal performance of SF1601G compare to standard FRDs?
SF1601G achieves RθJC = 1.5°C/W - significantly lower than typical fast recovery diodes (2.0–3.5°C/W in TO-220AB). This 25–50% improvement allows SF1601G to dissipate ~10.7W at 16°C junction-to-case rise, supporting higher current density in compact power supplies without oversized heatsinks. The benefit is most pronounced in convection-cooled industrial enclosures.
