Product details
Overview
SFS1601GH from Taiwan Semiconductor is a 16A, 50V 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 in DC-DC converters and freewheeling circuits.
For engineers reviewing the SFS1601GH datasheet, SFS1601GH pinout, SFS1601GH application, or SFS1601GH equivalent, key selection factors include its 50V VRRM, 0.975V typical forward voltage at 8A/25°C, dual-die configuration, J-STD-020 Level 1 moisture sensitivity, and RoHS/halogen-free compliance.
Technical Context
This device is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching applications. It delivers low conduction loss with 0.975V VF at 8A and rapid turn-off with 35ns reverse recovery time (trr), enabling efficient operation in snubber and freewheeling topologies.
The TO-263AB package provides robust thermal performance (RθJC = 2.5°C/W) and supports automated placement. Its AEC-Q101 qualification confirms suitability for automotive environments, including car lighting and powertrain auxiliary systems where reliability under thermal cycling and vibration is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage before breakdown; defines safe operating range in 12–24V automotive DC-DC stages. |
| IF | 16 A - Continuous forward current rating at case temperature ≤ 110°C; supports high-power buck converter outputs. |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); handles inductive kickback in motor drive freewheeling paths. |
| VF @ 8A, 25°C | 0.975 V - Low conduction loss per diode; reduces power dissipation and improves system efficiency at nominal load. |
| trr | 35 ns - Fast reverse recovery; minimizes switching losses and EMI in >100kHz SMPS designs. |
| RθJC | 2.5 °C/W - Efficient heat transfer to heatsink; enables compact thermal design without forced air cooling. |
| Junction Temp | −55°C to +150°C - Wide operating range compatible with under-hood automotive ambient conditions. |
Pinout & Package
TO-263AB (D2PAK) package with three terminals: Anode 1, Cathode (shared), Anode 2 - configured as dual independent dies in a single outline. Matte tin-plated leads meet J-STD-002 solderability requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Left) | Anode 1 | Input terminal for first rectifier die; connects to AC or switched node in dual-path configurations. |
| Pin 2 (Center) | Cathode | Common cathode output; ties both dies to positive rail in center-tapped or parallel rectification. |
| Pin 3 (Right) | Anode 2 | Input terminal for second rectifier die; enables independent control or redundancy in safety-critical paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, mechanical shock, and humidity testing. |
| Dual-die configuration | Enables independent or paralleled operation of two rectifiers in one footprint, reducing board area vs. discrete solutions. |
| Low VF (0.975V @ 8A) | Reduces conduction loss by ~15% vs. standard fast rectifiers, lowering thermal stress in space-constrained modules. |
| J-STD-020 Level 1 MSL | Zero bake requirement prior to reflow; supports direct placement into high-volume SMT lines without moisture mitigation steps. |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive; meets environmental compliance for global automotive OEMs. |

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-16EWH05 | Same 50V VRRM, 16A IF, but TO-220AC package; higher RθJC (3.0°C/W); no AEC-Q101 qualification. | Limited to industrial/non-automotive due to lack of automotive qualification and lower surge rating (100A). | Select when cost priority outweighs automotive compliance and thermal performance. |
| ON Semiconductor MUR1620CT | 200V VRRM, same TO-263AB package, 35ns trr, but higher VF (1.2V typ) and no AEC-Q101. | Higher voltage margin suits 24–48V systems but sacrifices efficiency in 12V automotive rails. | Choose only if system requires >50V reverse blocking and AEC-Q101 is not mandated. |
Compared with VS-16EWH05 and MUR1620CT, the SFS1601GH uniquely combines AEC-Q101 qualification, 50V optimization for 12V automotive systems, lowest VF in its class, and superior thermal resistance-making it the preferred choice for space- and efficiency-constrained automotive power stages.

FAQ
What is the maximum junction temperature rating for the SFS1601GH?
The SFS1601GH has a maximum junction temperature (TJ) of +150°C, with operational range from −55°C to +150°C. This rating enables reliable operation in under-hood automotive environments where ambient temperatures exceed 105°C. The device maintains specified electrical parameters up to this limit when thermal design ensures case temperature remains within derating curves shown in the datasheet.
Is the SFS1601GH pin-compatible with other parts in the SFS16xxGH family?
Yes, all SFS16xxGH devices-including SFS1601GH-share identical TO-263AB (D2PAK) package, pinout, and thermal characteristics. Only VRRM (50V to 600V) and forward voltage vary across the series. This allows drop-in replacement during design iteration or voltage-scaling without PCB changes.
Does the SFS1601GH require baking before reflow soldering?
No, the SFS1601GH is rated J-STD-020 Level 1 for moisture sensitivity, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without pre-bake. This simplifies manufacturing flow and eliminates risk of popcorn cracking during assembly.
What is the reverse recovery time (trr) specification for the SFS1601GH?
The SFS1601GH has a maximum reverse recovery time (trr) of 35ns, measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is confirmed across production lots and supports high-frequency switching (>200kHz) in DC-DC converters while minimizing switching losses and associated EMI.
How does the dual-die configuration of the SFS1601GH benefit circuit design?
The dual-die configuration in the SFS1601GH provides two independent anodes sharing one cathode, enabling flexible topologies such as dual-output rectification, interleaved freewheeling, or redundancy without adding discrete components. This reduces bill-of-materials count and PCB area versus two separate TO-263AB rectifiers.
