Product details
Overview
SFF1601G from Taiwan Semiconductor is a 16A, 50V super fast recovery rectifier diode in ITO-220AB package, featuring 35ns reverse recovery time, 0.975V forward voltage at 8A/25°C, and 125A surge current capability; used in DC-DC converters and freewheeling paths where low conduction loss and fast switching are required.
For engineers reviewing the SFF1601G datasheet, SFF1601G pinout, SFF1601G application, or SFF1601G equivalent, key selection criteria include VRRM = 50V, IF = 16A, trr = 35ns, RθJC = 1.5°C/W, and AEC-Q101 qualification availability (SFF1601GH variant), all critical for high-efficiency power stage design.
Technical Context
This device is a single-die, single-phase super fast rectifier optimized for switching-mode power supplies operating at frequencies up to several hundred kHz. Its 35ns reverse recovery time and low 0.975V forward voltage directly reduce switching losses and thermal stress under continuous 16A conduction.
The ITO-220AB package provides low 1.5°C/W junction-to-case thermal resistance and supports direct heatsink mounting with ≤0.56 N·m torque. Dual-die variants exist in the SFF160xG family, but SFF1601G is confirmed as single-die per datasheet absolute maximum ratings table and electrical specifications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF | 16 A - Continuous forward current rating defines maximum steady-state output current handling in DC-DC output stages. |
| VRRM | 50 V - Peak repetitive reverse voltage sets maximum blocking capability in low-voltage secondary-side rectification. |
| trr | 35 ns - Reverse recovery time determines switching loss and EMI generation during turn-off in hard-switched topologies. |
| VF | 0.975 V @ 8A, 25°C - Forward voltage directly impacts conduction loss and thermal rise in high-current paths. |
| IFSM | 125 A - Non-repetitive surge current rating supports inrush and fault transient tolerance without bond-wire failure. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance enables accurate heatsink sizing for 16A operation at TJ ≤ 150°C. |
Pinout & Package
Package: ITO-220AB - Insulated TO-220 variant with electrically isolated tab, matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and 1.70g mass.

Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | 35 ns trr minimizes switching loss and improves efficiency in 100–500 kHz SMPS designs. |
| Low forward voltage | 0.975 V @ 8A reduces conduction loss by ~15% vs. standard fast rectifiers with VF > 1.1V. |
| High surge robustness | 125 A IFSM withstands 8.3 ms half-sine surges common in automotive load-dump and startup transients. |
| UL Recognized | UL File #E-326243 confirms compliance with safety standards for end-equipment certification. |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side synchronous or diode rectification in isolated 12V–48V output DC-DC converters. IC Role / Device Role / Timing Role: Power rectifier converting transformer AC output to regulated DC; conducts during positive half-cycle of secondary winding voltage. Use Value: 0.975V VF and 35ns trr jointly reduce total power loss and improve light-load efficiency over standard FRDs. | Use Scenario: Freewheeling path across inductive loads (e.g., motor windings, solenoids) in H-bridge inverters. IC Role / Device Role / Timing Role: Provides low-impedance current recirculation path when high-side switch turns off, clamping inductive kickback. Use Value: 125A IFSM and 1.5°C/W RθJC ensure reliable energy dissipation during repeated inductive turn-off events. |
| Automotive On-Board Charger (OBC) Auxiliary Supply | Industrial PLC Power Module Input Stage |
Use Scenario: Auxiliary 12V/24V supply rectification in EV on-board chargers, where space and thermal constraints are tight. IC Role / Device Role / Timing Role: Primary rectifier in flyback or forward converter feeding control logic and gate drivers. Use Value: AEC-Q101 qualified version (SFF1601GH) meets automotive reliability requirements; ITO-220AB allows direct heatsink mounting without isolation hardware. | Use Scenario: Input rectification in industrial programmable logic controller (PLC) power modules accepting 24V–48V DC input. IC Role / Device Role / Timing Role: Front-end rectifier converting external DC supply to internal rail, often followed by buck regulation. Use Value: UL recognition and halogen-free construction support industrial safety and environmental compliance (IEC 61249-2-21). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-16EWH05-M3 | Same ITO-220AB package, 16A/50V, trr = 30ns, VF = 0.92V @ 8A - slightly faster and lower VF. | Optimized for ultra-low-loss 100–300 kHz converters; no AEC-Q101 option available. | Select when lowest possible conduction + switching loss is prioritized over automotive qualification. |
| ON Semiconductor MUR1620CT | Dual common-cathode configuration in TO-220AB, 16A/200V, trr = 35ns, VF = 0.97V - higher VRRM, same speed, but dual-diode topology. | Used in dual-output or center-tapped transformer rectification; requires circuit redesign for single-diode replacement. | Select only if dual-diode functionality is needed; not a drop-in replacement for SFF1601G's single-diode layout. |
Compared with VS-16EWH05-M3 and MUR1620CT, the SFF1601G offers the unique combination of 50V rating, 35ns recovery, and AEC-Q101-qualified variant (SFF1601GH), making it optimal for cost-sensitive, thermally constrained automotive auxiliary supplies where exact voltage rating and qualification matter.

FAQ
What is the maximum junction temperature rating for the SFF1601G?
The SFF1601G has a maximum junction temperature (TJ) rating of +150°C, as specified in the Absolute Maximum Ratings table. This allows operation in high-ambient environments such as automotive engine compartments or enclosed industrial enclosures when paired with appropriate heatsinking. Derating curves in the datasheet confirm usable current down to 125°C case temperature.
Is the SFF1601G pin-compatible with other devices in the SFF160xG family?
Yes, all SFF160xG devices-including SFF1601G-share identical ITO-220AB packaging, pinout, and thermal footprint. Only VRRM (50V to 600V) and forward voltage (0.975V to 1.700V) differ across the family. PCB layout designed for SFF1601G can accommodate any SFF160xG variant without modification.
Does the SFF1601G have AEC-Q101 qualification?
The base SFF1601G is not AEC-Q101 qualified, but the SFF1601GH variant is explicitly listed as AEC-Q101 qualified in the Ordering Information section. The "H" suffix denotes automotive-grade screening and testing per AEC-Q101 Rev D, including extended temperature cycling and bias-HAST.
What is the thermal resistance from junction to case for the SFF1601G?
The SFF1601G has a typical junction-to-case thermal resistance (RθJC) of 1.5°C/W, measured from die to the metal tab surface. This value enables accurate thermal modeling when mounted to a heatsink with known interface resistance, supporting reliable 16A operation at TJ ≤ 150°C under forced or natural convection.
How does the SFF1601G compare to standard fast recovery diodes in terms of reverse recovery performance?
The SFF1601G achieves 35ns reverse recovery time (trr), significantly faster than standard fast recovery diodes (typically 50–100ns). This reduction lowers switching losses and EMI in high-frequency converters. Its soft recovery characteristic-confirmed by trr test circuit in Fig.6-also minimizes voltage overshoot during turn-off compared to abrupt-recovery types.
