Product details
Overview
SFS1604GH from Taiwan Semiconductor is a 200V repetitive peak reverse voltage, 16A average forward current super fast recovery surface-mount rectifier in TO-263AB (D2PAK) package, with 0.975V max forward voltage at 8A/25°C and 35ns reverse recovery time - used in automotive DC-DC converters and freewheeling paths.
For engineers reviewing the SFS1604GH datasheet, SFS1604GH pinout, SFS1604GH application, or SFS1604GH equivalent, key selection criteria include VRRM = 200V, IF = 16A, trr = 35ns, VF ≤ 0.975V @ 8A, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This device is a single-die, common-cathode configured super fast recovery rectifier optimized for high-frequency switching applications. Its 35ns reverse recovery time and low 0.975V forward voltage drop at 8A reduce conduction and switching losses in synchronous and non-synchronous topologies.
The TO-263AB (D2PAK) package delivers 2.5°C/W junction-to-case thermal resistance and supports automated placement. It is rated for TJ = –55°C to +150°C and qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating range in flyback/freewheeling clamping |
| IF(AV) | 16 A - continuous forward current rating at TC = 110°C; determines heatsink sizing in high-duty-cycle operation |
| VF | ≤0.975 V @ 8A, 25°C - low conduction loss enabling >92% efficiency in 12V–48V DC-DC stages |
| trr | 35 ns - ultra-fast recovery minimizes switching node ringing and EMI in >100kHz converters |
| RθJC | 2.5 °C/W - enables direct PCB copper pour thermal path for high-power density layouts |
| AEC-Q101 | Qualified - validated for automotive under-hood temperature cycling, humidity, and mechanical shock requirements |
Pinout & Package
TO-263AB (D2PAK) package with three terminals: Anode 1, Cathode (common), Anode 2 - configured as dual-anode, single-cathode super fast rectifier. Matte tin-plated leads meet J-STD-002 solderability; polarity marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 | Input terminal for first diode path | Connects to switching node in half-bridge freewheeling or dual-phase output rectification |
| Cathode | Common output node (shared cathode) | Routes combined rectified current to output capacitor; requires low-inductance copper plane |
| Anode 2 | Input terminal for second diode path | Enables interleaved or dual-rail input handling; electrically isolated from Anode 1 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics per stress test conditions including HTOL, TC, UHAST |
| Super fast recovery (trr = 35 ns) | Reduces reverse recovery charge (Qrr) to <15 nC, limiting turn-off spikes in high-frequency SMPS |
| Low VF (≤0.975 V @ 8A) | Minimizes I²R conduction loss - critical for thermally constrained automotive modules with limited airflow |
| TO-263AB thermal performance (RθJC = 2.5°C/W) | Supports 16A continuous operation with ≤40°C rise above case when mounted on ≥250 mm² 2-oz copper |
| Moisture sensitivity level 1 | Zero bake requirement before reflow; compatible with standard SMT assembly lines without dry-pack handling |

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-16EWH02-M3 | VRRM = 200V, IF = 16A, trr = 30ns, VF = 0.92V @ 8A - slightly faster but lower surge rating (IFSM = 110A vs. 125A) | Same automotive qualification (AEC-Q101), but tighter VF distribution; preferred where EMI margin is critical | Select for lower EMI-sensitive designs; verify layout clearance for smaller D2PAK variant |
| ON Semiconductor MUR1620CTG | VRRM = 200V, IF = 16A, trr = 35ns, VF = 1.05V @ 8A - higher VF, same IFSM, TO-220AB package (not surface-mount) | Lacks AEC-Q101; requires through-hole assembly and larger footprint; unsuitable for automated automotive production | Use only in industrial prototypes or cost-sensitive non-automotive applications where reflow compatibility is not required |
Compared with VS-16EWH02-M3 and MUR1620CTG, the SFS1604GH offers optimal balance of AEC-Q101 compliance, 125A surge capability, and D2PAK manufacturability - making it the preferred choice for volume automotive power modules requiring zero rework on SMT lines.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for SFS1604GH?
The SFS1604GH has a VRRM of 200 V, confirmed in the Absolute Maximum Ratings table of the official TSC datasheet (Version A2103). This rating defines the highest reverse voltage the device can block repeatedly without breakdown under normal operating conditions and is specific to the SFS1604GH variant within the SFS1601GH–SFS1608GH family.
Is SFS1604GH qualified for automotive applications?
Yes, the SFS1604GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the TSC datasheet. This qualification covers temperature cycling, high-temperature operating life, and mechanical shock testing - confirming its suitability for under-hood automotive power systems such as 48V DC-DC converters and LED drivers.
What is the forward voltage (VF) specification for SFS1604GH at operating conditions?
The SFS1604GH has a maximum forward voltage of 0.975 V at IF = 8 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulse conditions (PW = 0.3 ms) and reflects conduction loss behavior critical for efficiency calculation in high-frequency switching applications.
Does SFS1604GH have a dual-anode configuration?
Yes, the SFS1604GH uses a dual-anode, single-cathode configuration in its TO-263AB (D2PAK) package, as indicated by the "Dual dies" note in KEY PARAMETERS and confirmed by the marking code "SFS1604G" and pinout structure. This allows independent anode connections while sharing a common cathode terminal.
What is the junction-to-case thermal resistance (RθJC) of SFS1604GH?
The SFS1604GH has a typical junction-to-case thermal resistance of 2.5°C/W, specified in the THERMAL PERFORMANCE section of the datasheet. This value applies to the TO-263AB package and enables accurate thermal modeling when designing PCB copper pours or external heatsinks for 16A continuous operation.
