Product details
Overview
SFS1603GH from Taiwan Semiconductor is a 150 V, 16 A super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 35 ns reverse recovery time, 0.975 V forward voltage at 8 A/25°C, and AEC-Q101 qualification for automotive-grade reliability-used in freewheeling and snubber circuits in DC-DC converters.
For engineers reviewing the SFS1603GH datasheet, SFS1603GH pinout, SFS1603GH application, or SFS1603GH equivalent, key selection criteria include repetitive peak reverse voltage (150 V), surge current capability (125 A), junction-to-case thermal resistance (2.5 °C/W), dual-die configuration, and moisture sensitivity level 1 compliance.
Technical Context
The SFS1603GH integrates two fast-recovery silicon dies in a single TO-263AB thermally enhanced package, enabling high-current freewheeling with low conduction loss and minimal switching loss. Its 35 ns trr and 80 pF junction capacitance support operation in high-frequency DC-DC topologies up to several hundred kHz.
Designed for automotive environments, the device meets AEC-Q101 stress testing requirements including temperature cycling, HTRB, and unbiased HAST. The matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance standards.

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-16EWH03-M3 | Same VRRM (150 V), IF (16 A), TO-263AB package; trr = 30 ns (slightly faster), VF = 0.92 V @ 8 A | Optimized for higher-frequency SMPS (>500 kHz); lower VF improves light-load efficiency | Preferred where <30 ns trr and sub-0.95 V VF are critical; verify layout compatibility with Vishay's pad dimensions |
| ON Semiconductor MUR1620CTG | Higher VRRM (200 V), same IF (16 A), TO-220AB package; trr = 35 ns, VF = 1.1 V @ 8 A | Through-hole mounting only; lacks AEC-Q101 qualification and moisture level 1 rating | Acceptable for non-automotive industrial supplies; not suitable for SMT automotive production or humid-environment deployment |
Compared with VS-16EWH03-M3 and MUR1620CTG, the SFS1603GH uniquely combines AEC-Q101 qualification, moisture level 1, dual-die D2PAK packaging, and 0.975 V VF-making it the only option qualified for automated SMT assembly in under-hood automotive converters requiring 150 V blocking.

FAQ
What is the maximum junction temperature rating for the SFS1603GH?
The SFS1603GH has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 requirements. This rating enables reliable operation in automotive under-hood environments when mounted on adequately sized copper areas or heatsinks. Thermal design must maintain TJ ≤ 150°C under worst-case ambient and power dissipation conditions, using the specified 2.5 °C/W RθJC value.
Is the SFS1603GH pin-compatible with other devices in the SFS160xGH family?
Yes, all SFS160xGH devices-including SFS1603GH-share identical TO-263AB (D2PAK) mechanical outline, pin assignment (Anode 1 / Cathode / Anode 2), and thermal pad layout. Voltage ratings differ across the family (50–600 V), but PCB footprint and assembly process are fully interchangeable for design flexibility and BOM consolidation.
Does the SFS1603GH require baking before reflow soldering?
No, the SFS1603GH carries moisture sensitivity level (MSL) 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without pre-baking. This eliminates dry-pack handling and reduces manufacturing overhead in high-volume SMT lines-confirmed by TSC's qualification report A2103.
What is the reverse recovery time (trr) specification for the SFS1603GH?
The SFS1603GH has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is consistent across the SFS1601GH–SFS1604GH subgroup and enables efficient operation in DC-DC converters switching up to 1 MHz, minimizing switching losses and EMI generation.
How does the dual-die configuration of the SFS1603GH benefit circuit design?
The SFS1603GH integrates two matched silicon dies in a single TO-263AB package with a common cathode. This allows designers to implement interleaved freewheeling or parallel current paths without discrete paralleling-reducing layout complexity, eliminating current-sharing resistors, and ensuring thermal symmetry between dies during high-current operation.
