Product details

Overview

SFS1602G 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 35ns reverse recovery time. It serves as a high-efficiency freewheeling or output rectifier in DC-DC converters and switching inverters operating up to 150°C junction temperature.

For engineers reviewing the SFS1602G datasheet, SFS1602G pinout, SFS1602G application, or SFS1602G equivalent, key selection criteria include its 100V V_RRM, 0.975V forward voltage at 8A/25°C, dual-die configuration, moisture sensitivity level 1 compliance, and RoHS/halogen-free qualification for industrial power conversion designs.

Technical Context

The SFS1602G integrates two independent silicon die in a single TO-263AB thermally optimized package, enabling high-current unidirectional conduction with low conduction loss and fast switching recovery. Its 35ns trr and 80pF junction capacitance support operation in high-frequency SMPS topologies up to several hundred kHz.

Designed for surface-mount automated assembly, the device uses matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The UL 94V-0 molding compound and 1.41g mass support reliable thermal dissipation in compact power modules.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-16CTH01-M3/45	100V V_RRM, 16A I_F, 35ns t_rr, but TO-220AC package (not surface-mount); R_θJC = 3.0°C/W	Requires through-hole assembly and larger heatsink; unsuitable for high-density SMT layouts	Select only if legacy through-hole design or manual assembly constraints apply
ON Semiconductor MUR1620CT	200V V_RRM, same 16A/125A ratings, but 60ns t_rr and TO-220AB package; VF = 1.1V @ 8A	Higher voltage rating trades off speed and conduction loss; not drop-in for 100V designs needing minimal V_F	Consider only when system-level V_RRM margin exceeds 150V and layout permits TO-220 footprint

Compared with VS-16CTH01-M3/45 and MUR1620CT, the SFS1602G delivers superior thermal performance (2.5°C/W), lower forward voltage, and native SMT compatibility-enabling higher power density and automated manufacturing without thermal or layout compromise.

FAQ

What is the maximum junction temperature rating for the SFS1602G?

The SFS1602G has a maximum junction temperature (T_J) of +150°C, with operational range from −55°C to +150°C. This rating allows reliable use in high-ambient environments such as enclosed industrial power supplies or under-hood automotive auxiliary converters. Thermal design must ensure that power dissipation-calculated using V_F × I_F and switching losses-keeps actual junction temperature below this limit, leveraging the device's 2.5°C/W R_θJC and proper PCB copper area.

Does the SFS1602G have a dual-diode configuration, and how are the terminals arranged?

Yes, the SFS1602G contains two independent silicon rectifier dies in a single TO-263AB (D2PAK) package. It features two anode terminals (Anode 1 and Anode 2) and one shared cathode terminal on the exposed metal tab. This arrangement supports dual-channel freewheeling, interleaved rectification, or redundancy in critical power paths without requiring separate devices or additional board area.

What is the reverse recovery time (t_rr) of the SFS1602G, and under what test conditions is it specified?

The SFS1602G has a reverse recovery time (t_rr) of 35 ns, measured under the condition: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A. This value reflects its super fast switching performance, enabling efficient operation in high-frequency switch-mode power supplies above 100 kHz. The low t_rr minimizes switching loss and associated EMI compared to standard or fast recovery rectifiers.

Is the SFS1602G compliant with RoHS and halogen-free requirements?

Yes, the SFS1602G is RoHS compliant and halogen-free according to IEC 61249-2-21. Its molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations meet EU RoHS Directive 2011/65/EU restrictions. This makes the SFS1602G suitable for export to regulated markets and integration into environmentally certified industrial and telecom equipment.

What is the moisture sensitivity level (MSL) of the SFS1602G, and does it require baking before reflow?

The SFS1602G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not moisture-sensitive and may be stored indefinitely at ambient conditions without dry packing. No pre-reflow baking is required, simplifying SMT line integration and eliminating yield loss risks associated with moisture-induced popcorning during reflow soldering.
