Product details
Overview
SFS1602GH from Taiwan Semiconductor is a 16A, 100V super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 125A surge capability, 2.5°C/W junction-to-case thermal resistance, and AEC-Q101 qualification for automotive use. It serves as a freewheeling or snubber diode in high-efficiency DC-DC converters and car lighting systems.
For engineers reviewing the SFS1602GH datasheet, SFS1602GH pinout, SFS1602GH application, or SFS1602GH equivalent, key selection factors include its 100V VRRM, 0.975V forward voltage at 8A/25°C, 35ns reverse recovery time, dual-die construction, and moisture sensitivity level 1 compliance.
Technical Context
This super fast rectifier uses dual silicon dies in a single TO-263AB package to deliver high current handling with low conduction loss and rapid switching. Its 35ns trr and 80pF junction capacitance support high-frequency operation in snubber and freewheeling roles.
The device operates across –55°C to +150°C junction temperature range, maintains ≤10µA reverse leakage at 25°C, and achieves 2.5°C/W thermal resistance-enabling compact thermal design in space-constrained automotive power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in 12–48V automotive bus applications. |
| IF | 16 A - Continuous forward current rating; supports high-power DC-DC output stages without forced cooling. |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); withstands load dump transients in vehicle electrical systems. |
| VF | 0.975 V @ 8A, 25°C - Low conduction loss reduces power dissipation and improves efficiency in high-duty-cycle freewheeling paths. |
| trr | 35 ns - Reverse recovery time; enables stable operation up to ~3 MHz switching frequencies in resonant converters. |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct heatsinking via PCB copper pour or external heatsink mounting. |
| Junction capacitance | 80 pF @ 1MHz, 4V - Limits displacement current in high-dv/dt snubber networks and affects EMI filter design. |
Pinout & Package

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-16EWH10 | Same 100V VRRM, 16A IF, but TO-220AC package; higher RθJC = 3.0°C/W; trr = 30ns. | Requires through-hole mounting and larger heatsink; not AEC-Q101 qualified. | Prefer SFS1602GH for SMT automotive designs requiring AEC-Q101 and lower thermal resistance. |
| ON Semiconductor MUR1620CT | Dual common-cathode configuration; 200V VRRM; 1.15V VF @ 8A; trr = 35ns; TO-220AB package. | Higher voltage rating but higher forward drop; not automotive-qualified; different pinout. | Choose SFS1602GH when 100V rating, AEC-Q101, and surface-mount compatibility are mandatory. |
Compared with VS-16EWH10 and MUR1620CT, the SFS1602GH offers superior thermal performance (2.5°C/W), AEC-Q101 validation, and SMT compatibility-making it the preferred choice for space-constrained, thermally demanding automotive power stages where reliability and assembly efficiency are critical.

FAQ
What is the maximum junction temperature rating for the SFS1602GH?
The SFS1602GH has a maximum junction temperature (TJ) of +150°C, with operational range from –55°C to +150°C. This rating enables use in under-hood automotive environments where ambient temperatures exceed 105°C, provided thermal design maintains junction temperature below this limit using the specified 2.5°C/W RθJC and adequate PCB copper area. The SFS1602GH datasheet confirms this value in the Absolute Maximum Ratings table.
Is the SFS1602GH suitable for use in AEC-Q101-compliant automotive designs?
Yes, the SFS1602GH is explicitly AEC-Q101 qualified per the manufacturer's documentation, with test reports covering temperature cycling, humidity, mechanical shock, and high-temperature operating life. It meets all stress test requirements for discrete semiconductors in automotive applications, making it suitable for safety-critical subsystems like lighting and engine control-provided layout and thermal design follow TSC's recommended guidelines for the SFS1602GH.
What is the forward voltage drop of the SFS1602GH under typical operating conditions?
The SFS1602GH exhibits a typical forward voltage (VF) of 0.975 V at 8 A and 25°C junction temperature, as specified in the Electrical Specifications table. At higher temperatures (e.g., 125°C), VF decreases slightly due to negative temperature coefficient of silicon diodes. This low VF directly reduces conduction losses in high-current freewheeling paths, improving system efficiency-especially in 12V automotive DC-DC converters where the SFS1602GH is commonly deployed.
Does the SFS1602GH have a defined reverse recovery time, and how does it impact switching performance?
Yes, the SFS1602GH 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 fast recovery enables clean commutation in high-frequency (>500 kHz) switching topologies such as LLC resonant converters and active clamp forward circuits. In practical terms, the SFS1602GH's 35 ns trr minimizes reverse recovery current spikes and associated EMI, supporting stable operation without additional snubbers in well-designed layouts.
What packaging and moisture sensitivity level applies to the SFS1602GH?
The SFS1602GH is supplied in TO-263AB (D2PAK) package on 800-unit tape-and-reel, with moisture sensitivity level (MSL) 1 per J-STD-020. MSL 1 means the device may be stored indefinitely at ≤30°C/85% RH and placed directly into reflow without baking-ideal for high-volume SMT lines. The matte tin-plated leads meet J-STD-002 solderability requirements, and the SFS1602GH marking includes "SFS1602G" plus date and factory codes per the official outline drawing.
