Product details
Overview
SFAF1602G from Taiwan Semiconductor is a 16A, 100V repetitive peak reverse voltage super fast rectifier diode in ITO-220AC package, featuring 0.975V forward voltage at 16A/25°C, 35ns reverse recovery time, and 130pF junction capacitance - deployed in DC-DC converters and switching inverters for high-efficiency power conversion.
For engineers reviewing the SFAF1602G datasheet, SFAF1602G pinout, SFAF1602G application, or SFAF1602G equivalent, key selection criteria include VRRM=100V, IF=16A, trr=35ns, RθJC=1.3°C/W, and AEC-Q101 qualification status (SFAF1602GH variant only).
Technical Context
The SFAF1602G uses a glass-passivated single-die silicon junction optimized for low conduction loss and fast switching. Its 100V VRRM, 200A IFSM, and 150°C maximum junction temperature support robust operation in high-frequency switching topologies.
With 130pF junction capacitance at 1MHz/4V and 35ns reverse recovery time under 0.5A/1.0A test conditions, it delivers reduced switching losses compared to standard fast recovery diodes in SMPS freewheeling paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage before breakdown; defines usable input voltage range in buck/boost stages. |
| IF | 16 A - Continuous average forward current rating; determines heatsink sizing and thermal derating margin. |
| VF | 0.975 V @ 16A, 25°C - Low forward drop reduces conduction loss and improves system efficiency at rated load. |
| trr | 35 ns - Fast reverse recovery minimizes switching loss and EMI in high-frequency (>100 kHz) converters. |
| RθJC | 1.3 °C/W - Thermal resistance from junction to case enables direct mounting to heatsink with predictable temperature rise. |
| CJ | 130 pF @ 1MHz, 4V - Low junction capacitance limits displacement current and dv/dt-induced turn-on risk. |
Pinout & Package
Package: ITO-220AC - Insulated TO-220 variant with isolated metal tab, UL 94V-0 molding compound, matte tin-plated leads, and 0.56 N·m max mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switching node (e.g., MOSFET drain) in freewheeling path; requires low-inductance layout. |
| Cathode | Forward current exit point | Connected to output rail or ground return; carries full load current and must handle 200A surge peaks. |
| Tab (isolated) | Thermal interface / mechanical anchor | Electrically isolated metal surface for heatsink attachment; no electrical connection required for circuit function. |
Key Features

Applications
| DC-DC Converter Output Stage | Switching Inverter Freewheeling Path |
|---|---|
Use Scenario: Secondary-side rectification in isolated flyback or forward converters delivering 12–48V outputs at up to 16A. IC Role / Device Role / Timing Role: Freewheeling diode conducting during MOSFET off-time; clamps inductive kickback and transfers energy to output capacitor. Use Value: 0.975V VF and 35ns trr reduce conduction + switching losses, enabling >92% efficiency at 100 kHz switching frequency. | Use Scenario: Bidirectional freewheeling in H-bridge motor drives or solar microinverters operating at 20–50 kHz. IC Role / Device Role / Timing Role: Unidirectional current path during inductive energy recirculation; blocks reverse voltage during active PWM phases. Use Value: 100V VRRM and 200A IFSM withstand motor back-EMF spikes and grid-synchronization transients without failure. |
| Industrial SMPS Input Rectification | Automotive On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: High-current AC input rectification in 1–3 kW industrial switch-mode power supplies. IC Role / Device Role / Timing Role: Primary-side bridge rectifier leg handling continuous 16A RMS current and line-voltage surges. Use Value: 1.3°C/W RθJC allows direct heatsink mounting with <10°C junction rise at full load, eliminating need for thermal interface pads. | Use Scenario: Auxiliary 12V supply generation in EV on-board chargers using flyback topology with 400V DC-link input. IC Role / Device Role / Timing Role: Output rectifier sustaining 100V reverse bias while delivering 10–15A to control logic and gate drivers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602D | VRRM=200V, VF=1.05V @ 16A, trr=30ns, TO-220AC package | Higher voltage rating suits 200V systems; slightly higher VF increases conduction loss by ~8% at 16A | Select when 200V blocking is required and 30ns trr provides marginal EMI advantage over SFAF1602G's 35ns. |
| ON Semi MUR1620CT | Dual common-cathode configuration, VRRM=200V, VF=1.15V @ 8A per diode, TO-220AB package | Not single-diode; dual topology requires PCB redesign; higher VF and lower per-leg current rating limit direct substitution | Consider only for new designs needing dual-output rectification; not a drop-in replacement for SFAF1602G. |
Compared with STTH1602D and MUR1620CT, the SFAF1602G offers optimal balance of 100V rating, 0.975V VF, and 35ns trr for cost-sensitive 100V SMPS designs where thermal resistance (1.3°C/W) and UL recognition are critical.

FAQ
What is the maximum junction temperature rating for the SFAF1602G?
The SFAF1602G has a maximum junction temperature (TJ) of +150°C, verified across its full operating range from –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed power supplies or automotive under-hood locations. Derating curves in the official datasheet define allowable forward current reduction above 25°C ambient, ensuring safe thermal margins for long-term SFAF1602G deployment.
Is the SFAF1602G RoHS and halogen-free compliant?
Yes, the SFAF1602G is fully RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating meets JEDEC J-STD-020 moisture sensitivity and J-STD-002 solderability standards. This compliance supports lead-free reflow assembly and aligns with global environmental directives applicable to the SFAF1602G.
Does the SFAF1602G have AEC-Q101 qualification?
The base SFAF1602G is not AEC-Q101 qualified; however, the SFAF1602GH variant - identical in all electrical and thermal specifications - is fully AEC-Q101 qualified. The "H" suffix denotes automotive-grade screening including temperature cycling, highly accelerated life testing (HALT), and board-level reliability validation. Engineers specifying SFAF1602G for automotive use must select SFAF1602GH to meet OEM component qualification requirements.
What is the reverse recovery time (trr) test condition for the SFAF1602G?
The SFAF1602G reverse recovery time is specified as 35ns maximum under the condition: IF = 0.5A, IR = 1.0A, IRR = 0.25A, measured at TA = 25°C. This standardized test reflects real-world behavior during hard-switching transitions in SMPS circuits. The value is confirmed across production lots and guaranteed in the official Taiwan Semiconductor datasheet for SFAF1602G.
Can the SFAF1602G be mounted directly to a heatsink?
Yes, the SFAF1602G in ITO-220AC package features an electrically isolated metal tab designed for direct heatsink mounting. With a junction-to-case thermal resistance of 1.3°C/W and matte tin-plated leads, it supports secure mechanical attachment at ≤0.56 N·m torque. No insulating washer is required, simplifying thermal design while maintaining electrical isolation - a key advantage of the ITO-220AC construction used in the SFAF1602G.
