Product details
Overview
SFAF1604G from Taiwan Semiconductor is a 16A, 200V 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 high-frequency DC-DC converters and freewheeling paths.
For engineers reviewing the SFAF1604G datasheet, SFAF1604G pinout, SFAF1604G application, or SFAF1604G equivalent, key selection criteria include VRRM=200V, IF=16A, trr=35ns, RθJC=1.3°C/W, and AEC-Q101 qualification availability (SFAF1604GH variant).
Technical Context
This super fast rectifier uses glass-passivated silicon die to achieve low conduction loss and rapid carrier recombination. Its 35ns reverse recovery time enables operation in switching-mode power supplies up to several hundred kHz without excessive switching loss.
The ITO-220AC package provides direct thermal path from junction to case (RθJC=1.3°C/W) and supports 200A non-repetitive surge current (IFSM). Polarity is marked on device body; terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling topologies |
| IF | 16 A - Continuous forward current rating at TC=100°C; determines heatsink sizing for steady-state conduction |
| trr | 35 ns - Reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; limits switching frequency and EMI in SMPS |
| VF | 0.975 V - Forward voltage drop at IF=16A, TJ=25°C; directly impacts conduction loss and thermal design |
| CJ | 130 pF - Junction capacitance at 1 MHz, VR=4.0V; affects high-frequency noise coupling and snubber design |
| RθJC | 1.3 °C/W - Junction-to-case thermal resistance; enables accurate thermal modeling when mounted to heatsink |
Pinout & Package
ITO-220AC package: single-diode configuration with anode and cathode leads; case serves as cathode terminal; polarity marked on body; 1.70g weight; UL 94V-0 molding compound; mounting torque ≤0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to positive side of input or inductive load; must withstand full IF and IFSM |
| Cathode (Case + Lead 2) | Forward current exit / heat sink interface | Electrically and thermally connected to heatsink; requires insulated mounting if case is not referenced to system ground |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances humidity resistance and long-term reliability under thermal cycling and high-voltage stress |
| Super fast recovery (35 ns) | Reduces switching loss and EMI generation compared to standard rectifiers in 100–500 kHz SMPS |
| Low VF (0.975 V @ 16A) | Lowers conduction loss by ~15–20% versus comparable 200V fast rectifiers, improving efficiency in high-current rails |
| UL Recognized (E-326243) | Validates safety compliance for end-equipment certification in industrial and automotive power supplies |
| AEC-Q101 qualified option | SFAF1604GH variant meets stress test requirements for automotive under-hood applications |
Applications
| DC-DC Converter Primary Side | Switching Inverter Freewheeling |
|---|---|
Use Scenario: High-efficiency isolated DC-DC converter operating at 200–300 kHz with 24–48V input and 12V/15A output. IC Role / Device Role / Timing Role: Output rectifier handling continuous 16A forward current and absorbing inductive energy during switch-off. Use Value: 0.975V VF minimizes conduction loss; 35ns trr prevents reverse recovery tail current from overlapping with high-side FET turn-on. | Use Scenario: Three-phase motor drive inverter using IGBTs with passive freewheeling paths across each phase leg. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback during IGBT commutation cycles. Use Value: 200V VRRM safely blocks bus voltage spikes; 200A IFSM withstands transient overload during stall or short-circuit events. |
| Industrial SMPS Secondary Rectification | Automotive On-Board Charger (OBC) Auxiliary Supply |
Use Scenario: 400W telecom power supply with synchronous rectification disabled on secondary side due to cost constraints. IC Role / Device Role / Timing Role: Main secondary-side rectifier converting transformer output to regulated 5V/12V rails. Use Value: 130pF CJ reduces capacitive coupling noise into control circuitry; RθJC=1.3°C/W allows compact heatsinking in dense PCB layouts. | Use Scenario: 1.5kW bidirectional OBC auxiliary power module supplying gate drivers and MCU from high-voltage battery bus. IC Role / Device Role / Timing Role: Input rectifier converting AC line or HV DC to stable intermediate DC bus for downstream DC-DC stages. Use Value: AEC-Q101-qualified SFAF1604GH variant ensures reliability under automotive temperature cycling (-40°C to +150°C junction); UL recognition simplifies system-level safety approval. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1602CW | VRRM=200V, trr=35ns, VF=0.95V @ 16A, but in TO-247AC package (higher RθJC=1.5°C/W) | Same voltage/current class; different mechanical footprint and thermal performance | Prefer when existing layout uses TO-247 heatsink; verify thermal margin given higher RθJC |
| ON Semi MUR1620CT | Dual common-cathode configuration (16A per diode), VRRM=200V, trr=35ns, VF=0.93V @ 16A, TO-220AB package | Offers dual-diode integration; not single-die like SFAF1604G | Select only if dual-channel topology is required; otherwise, single-diode ITO-220AC offers better thermal path |
Compared with STTH1602CW and MUR1620CT, the SFAF1604G delivers superior thermal resistance (1.3°C/W) in ITO-220AC, enabling higher power density in space-constrained industrial converters where heatsink interface efficiency is critical.

FAQ
What is the maximum junction temperature rating for SFAF1604G?
The SFAF1604G has a maximum junction temperature (TJ) of +150°C and a storage temperature range of –55°C to +150°C. This rating is validated across its full operating current and voltage range, supporting use in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when properly heatsinked.
Is SFAF1604G pin-compatible with other devices in the SFAF160xG family?
Yes, all SFAF160xG devices share identical ITO-220AC packaging, pinout, and thermal-mechanical dimensions - only VRRM and related parameters (e.g., VF, CJ) differ. The SFAF1604G can be substituted for SFAF1601G–SFAF1608G in the same footprint, provided the 200V rating meets system voltage requirements.
Does SFAF1604G meet automotive qualification standards?
The base SFAF1604G is not AEC-Q101 qualified, but the SFAF1604GH variant is explicitly rated to AEC-Q101. Both share identical electrical specs; the 'H' suffix denotes additional stress testing including temperature cycling, HTRB, and ESD per AEC-Q101 Rev D. Use SFAF1604GH for automotive applications.
What is the reverse leakage current specification for SFAF1604G at elevated temperature?
At TJ = 100°C and rated VR = 200V, the SFAF1604G exhibits a maximum reverse leakage current (IR) of 400 µA. At 25°C, IR is limited to 10 µA - critical for low-power standby modes and high-impedance sensing circuits where leakage could affect accuracy.
How does the junction-to-case thermal resistance of SFAF1604G impact heatsink design?
With RθJC = 1.3°C/W, the SFAF1604G transfers heat efficiently from die to case. For a 16A load at 0.975V VF, power dissipation is ~15.6W; using this RθJC, a 10°C max case-to-ambient rise requires a heatsink with RθCA ≤ 0.6°C/W - achievable with compact extruded aluminum designs in forced-air environments.
