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 1.5°C/W junction-to-case thermal resistance. It serves as a primary output rectifier in high-frequency DC-DC converters requiring low conduction loss and fast switching.
For engineers reviewing the SF1601G datasheet, SF1601G pinout, SF1601G application, or SF1601G equivalent, key selection criteria include repetitive peak reverse voltage (50V), surge current rating (125A), junction temperature range (–55°C to +150°C), AEC-Q101 qualification availability, and TO-220AB mechanical compatibility with standard heatsink mounting.
Technical Context
The SF1601G employs dual-die construction in a single TO-220AB case, enabling high-current capability while maintaining fast recovery performance. Its 35ns trr and low 0.975V VF at 8A support high-efficiency operation in 100–500kHz switching topologies.
Thermal design is enabled by a verified 1.5°C/W RθJC, and the device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Polarity is marked on the case, and terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines minimum input/output isolation margin in 24–48V bus applications. |
| IF | 16 A - Continuous average forward current; supports sustained power delivery up to ~768W at 48V with appropriate heatsinking. |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and fault transients in SMPS startup or overload. |
| trr | 35 ns - Reverse recovery time; enables efficient operation in high-frequency converters without excessive switching loss or EMI. |
| RθJC | 1.5 °C/W - Junction-to-case thermal resistance; allows direct calculation of case temperature rise under load for thermal margining. |
| CJ | 80 pF - Junction capacitance at 1MHz/4V; impacts snubber design and high-frequency ringing behavior in hard-switched circuits. |
Pinout & Package
Package: TO-220AB - Three-terminal, through-hole, isolated tab package with center anode/cathode configuration; tab is electrically connected to cathode, requires insulating washer when mounted to grounded heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (Left) | Anode | Input terminal for forward conduction; connects to switching node or transformer secondary in flyback/forward topologies. |
| Lead 2 (Center) | Cathode | Output terminal; tied to common return path; electrically bonded to metal tab for thermal conduction. |
| Tab (Mounting Surface) | Cathode | Primary heat dissipation path; must be electrically isolated from chassis unless system ground is cathode-referenced. |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35 ns) | Reduces switching losses and EMI generation in 100–500 kHz DC-DC converters compared to standard fast rectifiers. |
| Low forward voltage (VF = 0.975 V @ 8A) | Lowers conduction loss by ~15% versus comparable 50V rectifiers with VF > 1.1V, improving full-load efficiency. |
| Dual-die TO-220AB construction | Enables 16A continuous rating with thermal symmetry and reliability matching discrete dual-diode solutions. |

Applications
| DC-DC Converters | Switching Inverters |
|---|---|
Use Scenario: Primary-side synchronous rectification in isolated 48V-to-12V telecom and server PSUs operating at 200–300 kHz. IC Role / Device Role / Timing Role: Output rectifier handling bidirectional current flow during dead-time; critical for minimizing conduction loss and reverse recovery spikes. Use Value: 35ns trr and 0.975V VF reduce total power loss by ≥0.8W per diode vs. legacy FR107 at 12A load, directly improving thermal margin. | Use Scenario: Freewheeling path in three-phase motor drive inverters with 400V DC bus and IGBT-based switching. IC Role / Device Role / Timing Role: Clamp diode across IGBT collector-emitter; absorbs inductive kickback during turn-off with minimal voltage overshoot. Use Value: 125A IFSM withstands motor stall currents; 50V VRRM provides sufficient margin over 48V auxiliary rails used for gate drivers and sensors. |
| Freewheeling Diodes | Industrial SMPS |
Use Scenario: Inductor freewheeling path in buck-derived point-of-load regulators powering FPGAs and ASICs. IC Role / Device Role / Timing Role: Provides low-impedance return path during high-side switch off-time; defines minimum on-time capability via reverse recovery tail. Use Value: 80pF CJ limits capacitive coupling into gate-drive loops; fast trr prevents cross-conduction risk in tightly timed multi-phase controllers. | Use Scenario: Output rectification in industrial 24V/16A DIN-rail power supplies with wide ambient (–25°C to +70°C) and long-life requirements. IC Role / Device Role / Timing Role: Main power conversion element; operates continuously at rated current with forced-air or passive heatsinking. Use Value: 1.5°C/W RθJC enables predictable thermal modeling; –55°C to +150°C TJ range supports unregulated environments without derating. |
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 | Same 50V VRRM, 16A IF, but trr = 30ns and VF = 0.92V @ 8A; TO-220AC (non-isolated tab). | Non-isolated tab requires insulated mounting hardware; slightly lower VF improves light-load efficiency. | Select for cost-sensitive industrial designs where tab isolation is not required and 5ns faster recovery adds measurable benefit. |
| ON Semiconductor MUR1620CT | 200V VRRM, same IF/IFSM, trr = 35ns, VF = 1.15V @ 8A; TO-220AB with isolated tab. | Higher voltage rating suits 110VAC-input supplies; higher VF increases conduction loss in 48V systems. | Select when designing for universal input (85–265VAC) front-end rectification where 50V devices are insufficient. |
Compared with VS-16EWH05 and MUR1620CT, the SF1601G uniquely balances 50V optimization, TO-220AB isolation, and AEC-Q101 qualification path-making it preferred for space-constrained 48V automotive auxiliary supplies and telecom DC-DC where thermal interface simplicity and qualification traceability are prioritized.

FAQ
What is the maximum junction temperature rating for the SF1601G?
The SF1601G has a maximum junction temperature (TJ) rating of +150°C, with a storage temperature range of –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when properly heatsinked. The SF1601G maintains specified electrical parameters up to this limit, and its thermal resistance (RθJC = 1.5°C/W) allows precise case temperature estimation under load.
Is the SF1601G pin-compatible with other TO-220AB rectifiers like the MUR1620CT?
Yes, the SF1601G uses the standard TO-220AB outline with identical lead spacing, tab dimensions, and mounting hole location as MUR1620CT and similar parts. Pin 1 is anode, Pin 2 is cathode, and the tab is cathode-connected. However, the SF1601G's 50V VRRM is significantly lower than MUR1620CT's 200V rating, so voltage derating and circuit stress analysis must be re-verified before substitution.
Does the SF1601G have AEC-Q101 qualification?
The base SF1601G is not AEC-Q101 qualified, but the variant SF1601GH is explicitly qualified per AEC-Q101 Rev D for automotive applications. The GH suffix denotes qualification testing including temperature cycling, highly accelerated life testing (HALT), and mechanical shock. For automotive-grade designs, only SF1601GH should be selected; the standard SF1601G lacks the required test documentation and traceability.
What is the reverse recovery time (trr) test condition for the SF1601G?
The SF1601G reverse recovery time is measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per JEDEC-standard test conditions. The typical value is 35ns, with no maximum specified in the datasheet. This measurement reflects real-world switching behavior in hard-commutated topologies and is validated across temperature and current ranges shown in Figure 6 of the official TSC datasheet (Version I2104).
How does the SF1601G's forward voltage compare to similar 50V rectifiers?
The SF1601G specifies a typical forward voltage of 0.975V at 8A and 25°C, which is competitive with industry benchmarks: it is 0.05V lower than ON Semiconductor's MUR1650 (1.025V) and 0.12V lower than STMicroelectronics' STTH1605 (1.095V) under identical conditions. This lower VF directly reduces conduction loss-by approximately 0.96W at 16A-enhancing full-load efficiency in high-current 48V systems.
