Product details
Overview
SFS1607G from Taiwan Semiconductor is a 16A, 600V super fast surface-mount rectifier in TO-263AB (D2PAK) package, configured with dual dies for high-efficiency DC/DC conversion and freewheeling paths in switching power supplies. It delivers VF = 1.700 V at IF = 8 A, TJ = 25°C; trr = 35 ns; IR ≤ 10 µA at VR = 600 V, TJ = 25°C; and RθJC = 2.5 °C/W.
For engineers reviewing the SFS1607G datasheet, SFS1607G pinout, SFS1607G application, or SFS1607G equivalent, key selection criteria include its 600V VRRM rating, 125A IFSM surge capability, low junction capacitance (60 pF), thermal performance, and suitability for high-frequency switching converters requiring fast recovery and low conduction loss.
Technical Context
The SFS1607G is a dual-die super fast recovery rectifier optimized for high-frequency switching topologies. Its 35 ns reverse recovery time and 60 pF junction capacitance per diode minimize switching losses and EMI generation in SMPS operating above 50 kHz.
Rated for 16 A average forward current and 600 V repetitive peak reverse voltage, it operates across –55°C to +150°C junction temperature range with 2.5 °C/W junction-to-case thermal resistance - enabling compact heatsink integration in space-constrained industrial and telecom power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input stages of 400 VAC rectified systems and 380–400 VDC bus designs |
| IF(AV) | 16 A - sustains continuous output current in 200–500 W isolated DC/DC converters |
| IFSM | 125 A - withstands inrush and transient surges without degradation in PFC or LLC resonant circuits |
| VF @ 8A, 25°C | 1.700 V - limits conduction loss to ~13.6 W per diode at full load, critical for thermal management |
| trr | 35 ns - enables operation up to ~2 MHz switching frequency before recovery-related losses dominate |
| RθJC | 2.5 °C/W - allows direct mounting to PCB copper pour or small heatsink for <10°C rise at 16 A |
| CJ | 60 pF - reduces capacitive coupling noise and improves EMI filter effectiveness in high-dV/dt environments |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, single-ended anode-cathode configuration with exposed cathode tab for thermal and electrical connection. Polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | 600 V VRRM, 16 A IF, trr = 35 ns, VF = 1.75 V @ 8 A - slightly higher forward drop | Same TO-220AC package; requires mechanical mounting and separate thermal interface | Preferred where legacy TO-220 footprint compatibility is required and board-level thermal design permits discrete heatsinking |
| IXYS MUR1660CT | 600 V VRRM, 16 A IF, trr = 35 ns, VF = 1.7 V @ 8 A - dual common-cathode configuration, same D2PAK package | Identical pinout and thermal profile; rated for TJ = 175°C (vs. 150°C for SFS1607G) | Recommended when extended junction temperature margin (>150°C) or long-term reliability under sustained overload is prioritized |
Compared with STTH1606D and IXYS MUR1660CT, the SFS1607G offers identical electrical performance in a surface-mount D2PAK package with level-1 moisture sensitivity - simplifying automated assembly and reducing thermal interface complexity, while maintaining competitive VF and trr at lower cost-per-watt in high-volume telecom and industrial power supplies.

FAQ
What is the maximum junction temperature rating for the SFS1607G?
The SFS1607G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This rating is validated under specified thermal conditions including RθJC = 2.5 °C/W and proper PCB copper pour design. Exceeding +150°C risks permanent degradation of the silicon die and metallization integrity in the SFS1607G.
Does the SFS1607G support lead-free reflow soldering?
Yes, the SFS1607G features matte tin-plated leads compliant with J-STD-002 and qualified for both lead-free (peak 260°C) and SnPb reflow profiles. Its moisture sensitivity level 1 classification eliminates pre-bake requirements, making it fully compatible with standard high-volume SMT assembly lines without process adjustment for the SFS1607G.
What is the reverse recovery time (trr) specification for the SFS1607G?
The SFS1607G has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed across production lots and applies directly to the SFS1607G - enabling efficient operation in switching power supplies up to 1–2 MHz before recovery losses dominate.
Is the SFS1607G pin-compatible with other devices in the SFS160xG family?
Yes, all SFS1601G through SFS1608G share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. The SFS1607G uses the same anode–cathode terminal configuration and marking orientation as the rest of the family, allowing direct substitution within the same voltage grade group when thermal and electrical margins permit.
What is the typical junction capacitance (CJ) of the SFS1607G?
The SFS1607G exhibits a typical junction capacitance (CJ) of 60 pF per diode, measured at 1 MHz and VR = 4.0 V. This value is confirmed in the official TSC datasheet Version O2103 and is consistent across SFS1605G–SFS1608G variants - critical for minimizing high-frequency displacement current and EMI in fast-switching applications using the SFS1607G.
