Product details
Overview
SFS1608GH from Taiwan Semiconductor is a 16A, 600V super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.700V forward voltage at 8A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-efficiency DC-DC converters operating up to 150°C junction temperature.
For engineers reviewing the SFS1608GH datasheet, SFS1608GH pinout, SFS1608GH application, or SFS1608GH equivalent, key selection criteria include its 600V VRRM, dual-die configuration, 125A IFSM, JESD201 Class 2 whisker resistance, and suitability for automotive lighting and industrial power supplies requiring robust surge handling and low thermal resistance (RθJC = 2.5°C/W).
Technical Context
This device is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching topologies. Its 35ns trr and 60pF junction capacitance support efficient operation in 100–500kHz DC-DC stages, while the 2.5°C/W junction-to-case thermal resistance enables high-power dissipation with minimal heatsinking.
The SFS1608GH uses epitaxial planar construction with soft-recovery characteristics, delivering stable reverse leakage (<400µA at 125°C) and consistent forward conduction across its full -55°C to +150°C operating range. Its matte tin-plated leads meet J-STD-002 solderability and J-STD-020 MSL Level 1 requirements.
Key Specifications

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-16EWH06-M3 | Same 600V VRRM, 16A IF, but 50ns trr and 3.0°C/W RθJC; no AEC-Q101 certification. | Not qualified for automotive use; limited to industrial/commercial DC-DC where qualification is not mandated. | Select when cost sensitivity outweighs automotive compliance and thermal performance. |
| ON Semiconductor MUR1660CTG | 600V, dual common-cathode configuration, but 60ns trr, 200µA max IR at 125°C, and TO-220AC package. | Through-hole mounting only; higher thermal resistance limits power density in SMT designs. | Choose only if legacy TO-220 layout reuse is required and surface-mount constraints do not apply. |
Compared with VS-16EWH06-M3 and MUR1660CTG, the SFS1608GH delivers superior automotive qualification, faster recovery (35ns vs. ≥50ns), lower thermal resistance (2.5°C/W), and surface-mount compatibility-making it the optimal choice for next-generation automotive power modules and high-density industrial converters.

FAQ
What is the maximum junction temperature rating for the SFS1608GH?
The SFS1608GH has a maximum junction temperature (TJ) of +150°C, with operational capability from -55°C to +150°C. This rating is validated per AEC-Q101 stress testing and enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves in the datasheet define safe IF limits above 25°C ambient.
Is the SFS1608GH pin-compatible with other parts in the SFS160xGH family?
Yes, all SFS160xGH variants-including SFS1608GH-share identical TO-263AB (D2PAK) package dimensions, pinout, and thermal pad layout. The only differences are VRRM (50V–600V) and corresponding forward voltage; thus, SFS1608GH can be substituted within the same footprint when 600V blocking is required.
Does the SFS1608GH have a common cathode or independent cathodes?
The SFS1608GH features a common cathode configuration: both anodes are electrically isolated, but the cathodes are internally bonded to the shared metal tab. This structure supports dual-channel freewheeling or parallel operation with a single thermal interface, as confirmed in the mechanical data and marking diagram.
What is the reverse leakage current specification for SFS1608GH at elevated temperature?
At TJ = 125°C and rated VR, the SFS1608GH exhibits a maximum reverse leakage current (IR) of 400 µA, per the electrical specifications table. This value is measured under 30ms pulse conditions and remains stable across production lots, supporting predictable thermal design in high-temperature applications.
How does the SFS1608GH's 35ns reverse recovery time impact EMI in switching circuits?
The 35ns trr of the SFS1608GH reduces high-frequency ringing and dv/dt-induced noise during diode turn-off, directly lowering conducted EMI in DC-DC converters. When paired with optimized snubbers, this enables simpler EMI filter designs and helps meet CISPR 25 Class 5 requirements in automotive power systems using the SFS1608GH.
