Product details

Overview

SFS1604G from Taiwan Semiconductor is a 200 V repetitive peak reverse voltage, 16 A average forward current super fast surface-mount rectifier in TO-263AB (D2PAK) package, with 0.975 V forward voltage at 8 A and 25°C junction temperature, used for freewheeling and DC-DC converter output rectification.

For engineers reviewing the SFS1604G datasheet, SFS1604G pinout, SFS1604G application, or SFS1604G equivalent, key selection criteria include its 200 V V_RRM, 125 A non-repetitive surge rating, 35 ns reverse recovery time, 80 pF junction capacitance at 4 V, and thermal resistance of 2.5 °C/W - all critical for high-frequency switching power supply design.

Technical Context

The SFS1604G is a single-die, single-phase super fast recovery rectifier optimized for high-efficiency, high-frequency switching applications. It features low Q_rr and tight trr distribution, enabling reduced switching losses in synchronous and quasi-resonant topologies.

Its 2.5 °C/W junction-to-case thermal resistance supports high-power density layouts when mounted on copper-clad PCBs with thermal pads. The device operates across -55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1602CW	200 V V_RRM, 16 A I_F, 1.05 V V_F @ 8 A, 30 ns t_rr, TO-247AC package	Higher V_F and larger through-hole package; lower thermal resistance but requires hole mounting	Preferred where higher surge margin and legacy through-hole assembly exist; not suitable for space-constrained SMT designs
ON Semiconductor MUR1620CT	200 V V_RRM, dual common-cathode configuration, 1.15 V V_F @ 8 A, 60 ns t_rr, TO-220AB package	Dual-diode layout and slower recovery increase conduction loss and limit max switching frequency	Acceptable for lower-frequency (<100 kHz) industrial supplies; avoid in high-density or high-frequency SMPS

Compared with STTH1602CW and MUR1620CT, the SFS1604G delivers superior thermal performance in surface-mount form factor, tighter t_rr control than MUR1620CT, and lower V_F than both - making it optimal for compact, high-efficiency 200–300 kHz DC-DC and inverter designs requiring automated assembly.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the SFS1604G?

The SFS1604G has a maximum repetitive peak reverse voltage (V_RRM) of 200 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version O2103). This rating defines the highest reverse-biased voltage the device can block continuously without breakdown, and is fixed for the SFS1604G within the SFS1601G–SFS1608G family.

What is the forward voltage (V_F) of the SFS1604G under typical operating conditions?

The SFS1604G exhibits a maximum forward voltage (V_F) of 0.975 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 represents the conduction loss baseline used for thermal and efficiency calculations in real-world SFS1604G applications.

Does the SFS1604G have a specified reverse recovery time (t_rr)?

Yes, the SFS1604G has a specified reverse recovery time (t_rr) of 35 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is explicitly listed in the Electrical Specifications section of the Taiwan Semiconductor datasheet and confirms the device's suitability for high-frequency switching applications up to ~500 kHz.

What package type does the SFS1604G use, and is it lead-free?

The SFS1604G uses the TO-263AB (D2PAK) surface-mount package with matte tin-plated leads and green molding compound. It is RoHS compliant and halogen-free per IEC 61249-2-21, and its moisture sensitivity level is rated J-STD-020 Level 1 - meaning it can be stored indefinitely at ambient conditions without baking prior to reflow.

Is the SFS1604G suitable for automotive applications?

The SFS1604G is not qualified to AEC-Q101 or automotive-grade reliability standards. While it operates across -55°C to +150°C junction temperature and meets industrial-level robustness requirements (JESD201 Class 2 whisker test, J-STD-020 Level 1), Taiwan Semiconductor explicitly states these devices are "not designed for use in medical, life-saving, or life-sustaining applications" - and automotive safety-critical systems fall under this restriction unless separately qualified.
