Product details
Overview
SFAF1607G from Taiwan Semiconductor is a 16A, 500V super fast rectifier diode in ITO-220AC package, featuring 1.700V forward voltage at 16A/25°C, 35ns reverse recovery time, and 100pF junction capacitance - deployed in high-frequency DC-DC converters requiring low-loss freewheeling paths.
For engineers reviewing the SFAF1607G datasheet, SFAF1607G pinout, SFAF1607G application, or SFAF1607G equivalent, key selection criteria include VRRM = 500V, IF = 16A, trr = 35ns, RθJC = 1.3°C/W, and AEC-Q101 qualification status (SFAF1607GH variant only).
Technical Context
This super fast rectifier uses a glass-passivated silicon junction to achieve high surge capability (IFSM = 200A) and stable operation up to TJ = 150°C. Its 35ns trr and low CJ (100pF) support switching frequencies beyond 100kHz in SMPS topologies.
The ITO-220AC package provides direct heatsink mounting with 0.56 N·m max torque and UL 94V-0 molding compound. Polarity is marked on the device body, and terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum repetitive reverse blocking voltage; defines usable input voltage range in boost/flyback stages |
| IF | 16 A - continuous forward current rating at TC = 100°C; sets minimum heatsink requirement for steady-state conduction |
| VF | 1.700 V @ 16A, 25°C - forward drop directly impacts conduction loss and thermal design in high-current paths |
| trr | 35 ns - reverse recovery time determines switching loss and EMI behavior in hard-switched converters |
| RθJC | 1.3 °C/W - junction-to-case thermal resistance enables accurate die temperature estimation under forced-air or heatsink cooling |
| CJ | 100 pF @ 4V - junction capacitance affects snubber sizing and high-frequency ringing in resonant circuits |
Pinout & Package
ITO-220AC package: single-diode configuration with anode and cathode leads mounted on insulated tab; tab is electrically connected to cathode; matte tin-plated leads; 1.70g mass; UL Recognized File #E-326243.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to switching node or transformer secondary; must withstand peak reverse voltage and surge current |
| Cathode (Lead 2) | Output current exit point | Electrically tied to metal tab; requires isolation from heatsink unless referenced to system ground |
| Tab (Cathode) | Thermal and electrical path | Primary heat dissipation surface; electrically active - insulation required if not at common reference potential |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35 ns) | Enables efficient operation in 50–500 kHz SMPS without excessive switching loss or voltage overshoot |
| Glass passivated junction | Ensures long-term reliability under humidity, thermal cycling, and high dv/dt stress in automotive-grade environments |
| UL Recognized (E-326243) | Validates flammability (UL 94V-0), terminal solderability (J-STD-002), and whisker resistance (JESD201 Class 2) |
| AEC-Q101 qualified option (SFAF1607GH) | Supports automotive powertrain and body electronics where component-level stress testing is mandated |
Applications
| DC-DC Converters | Switching Inverters |
|---|---|

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 | VRRM = 500V, trr = 35ns, VF = 1.75V @ 16A - slightly higher forward drop; TO-220AC package | Same VRRM and trr | Acceptable for non-AEC-Q101 designs where 50mV higher VF is tolerable in thermal budget |
| IXYS MUR1650CT | Dual common-cathode configuration; VRRM = 500V, trr = 35ns, VF = 1.7V - requires PCB layout change due to dual-die footprint | Designed for dual-phase or interleaved topologies; not single-device drop-in | Select only when dual-diode functionality is needed; verify thermal coupling between dies in shared heatsink |
Compared with STTH1605D and IXYS MUR1650CT, the SFAF1607G offers identical VRRM and trr but lower VF than STTH1605D and single-die simplicity versus MUR1650CT's dual configuration - making it optimal for space-constrained, single-channel 500V rectification.

FAQ
What is the maximum junction temperature rating for SFAF1607G?
The SFAF1607G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table. This allows continuous operation in high-ambient industrial environments when paired with appropriate heatsinking. Derating curves confirm usable current down to TC = 125°C. The SFAF1607G must not exceed this limit to maintain reliability and avoid parametric shift.
Is SFAF1607G AEC-Q101 qualified?
The base SFAF1607G is not AEC-Q101 qualified; however, the SFAF1607GH variant - indicated by the "H" suffix in the ordering code - is fully AEC-Q101 qualified. Both share identical electrical specs, but only SFAF1607GH undergoes automotive-grade stress testing including temperature cycling, HTRB, and UHAST. Always specify "H" for automotive applications.
What is the reverse recovery time (trr) of SFAF1607G and under what test conditions?
The SFAF1607G has a typical reverse recovery time (trr) of 35ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the electrical specifications table. This value is confirmed across the SFAF1605G–SFAF1608G group and applies directly to the SFAF1607G. It reflects performance at room temperature and supports high-frequency switching up to ~300kHz.
Does SFAF1607G have a UL recognition rating?
Yes, the SFAF1607G is UL Recognized under File #E-326243. This certification covers flammability (UL 94V-0), terminal solderability (J-STD-002), and tin whisker resistance (JESD201 Class 2). The UL mark applies to the ITO-220AC package and confirms compliance for use in end-equipment requiring safety agency approval.
What is the junction-to-case thermal resistance (RθJC) of SFAF1607G?
The SFAF1607G has a typical junction-to-case thermal resistance (RθJC) of 1.3°C/W, as specified in the Thermal Performance section. This value is measured with the device mounted to a flat, bare copper heatsink using recommended mounting torque (≤0.56 N·m). It enables accurate thermal modeling for heatsink sizing in 16A continuous applications.
