Product details
Overview
SFS1605GH from Taiwan Semiconductor is a 16A, 400V repetitive peak reverse voltage (VRRM) super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.300V max 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.
For engineers reviewing the SFS1605GH datasheet, SFS1605GH pinout, SFS1605GH application, or SFS1605GH equivalent, key selection criteria include its 400V VRRM, dual-die configuration, 125A IFSM, junction-to-case thermal resistance of 2.5°C/W, and moisture sensitivity level 1 compliance - all critical for automotive lighting and industrial power supply designs.
Technical Context
The SFS1605GH implements a dual-die super fast recovery rectifier structure optimized for low switching loss and high surge robustness. Its 35ns trr and 60pF junction capacitance support operation in high-frequency (>100kHz) DC-DC topologies, while the 400V VRRM rating targets mid-voltage automotive and industrial bus applications.
Thermally, the device leverages the TO-263AB package's low RθJC of 2.5°C/W to sustain 16A continuous forward current at case temperatures up to 115°C. Its AEC-Q101 qualification confirms stress-tested performance across -55°C to +150°C junction temperature range under automotive environmental conditions.

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-16EWH04FN-M3 | Same 400V VRRM, 16A IF, but TO-220AC package; 1.25V VF @ 8A; 30ns trr; no AEC-Q101 | Requires through-hole mounting and heatsink; not qualified for automotive vibration/temperature cycling | Preferred where board space allows through-hole and automotive qualification is unnecessary |
| ON Semiconductor MUR1640CT | 400V VRRM, 16A IF, TO-220AB package; 1.7V VF @ 8A; 60ns trr; no AEC-Q101 | Higher conduction loss and slower recovery; unsuitable for >200kHz operation or automotive environments | Lower-cost option for non-automotive 50–100kHz industrial supplies with relaxed efficiency targets |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SFS1605GH?
The SFS1605GH has a maximum repetitive peak reverse voltage (VRRM) of 400 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103). This rating applies across the full operating junction temperature range of -55°C to +150°C and defines the highest reverse voltage the device can block continuously without breakdown. The SFS1605GH is part of the SFS1601GH–SFS1608GH family, where the fifth digit '5' directly corresponds to the 400V rating.
Is SFS1605GH qualified for automotive applications?
Yes, the SFS1605GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), highly accelerated stress test (HAST), and unbiased highly accelerated stress test (UHAST). The device is intended for automotive applications such as LED headlamps, body control modules, and engine management subsystems where reliability under harsh thermal and vibrational conditions is mandatory.
What is the forward voltage drop (VF) of SFS1605GH at rated current?
The SFS1605GH exhibits a maximum forward voltage drop (VF) of 1.300 V at 8 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects typical conduction loss in high-duty-cycle rectification. At higher temperatures or currents, VF increases predictably per the Typical Forward Characteristics curve in the datasheet.
What package type does SFS1605GH use, and is it lead-free?
The SFS1605GH uses the TO-263AB (D2PAK) surface-mount package with matte tin-plated leads, fully compliant with J-STD-002 solderability standards. It is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the device carries moisture sensitivity level 1 per J-STD-020 - confirming full lead-free compatibility and no bake requirement before reflow soldering.
What is the reverse recovery time (trr) specification for SFS1605GH?
The SFS1605GH has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the Electrical Specifications table. This ultra-fast recovery enables efficient operation in high-frequency switching power supplies (100–500 kHz), minimizing switching losses and associated EMI generation compared to standard or fast recovery rectifiers.
