Product details

Overview

SF64G from Taiwan Semiconductor is a 200V, 6A super fast recovery rectifier diode in DO-201AD package, featuring 35ns reverse recovery time, 0.975V forward voltage at 6A/25°C, and 150A surge capability - deployed in DC-DC converters and switching inverters requiring low conduction loss and fast commutation.

For engineers reviewing the SF64G datasheet, SF64G pinout, SF64G application, or SF64G equivalent, key selection criteria include V_RRM = 200V, I_F = 6A, t_rr = 35ns, V_F = 0.975V, and thermal resistance R_θJL = 5°C/W - all critical for high-frequency power stage efficiency and thermal management.

Technical Context

The SF64G is a single-die, planar junction super fast rectifier optimized for high-frequency switching applications. Its 35ns reverse recovery time and low 0.975V forward voltage at rated current enable reduced switching losses and improved system efficiency in SMPS topologies.

Designed with pure tin-plated leads compliant with J-STD-002 and JESD201 Class 2 whisker testing, the device supports lead-free reflow soldering. The DO-201AD package provides 5°C/W junction-to-lead thermal resistance, enabling reliable operation up to 150°C junction temperature.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH6S02	V_RRM = 200V, I_F = 6A, t_rr = 35ns, V_F = 0.95V - Slightly lower V_F, same recovery speed, TO-220AC package.	Requires different mounting (tabbed TO-220 vs. axial DO-201AD); higher thermal mass but needs heatsink for same power level.	Select STTH6S02 when board space permits larger footprint and heatsink integration is preferred for >5W dissipation.
ON Semi MUR620	V_RRM = 200V, I_F = 6A, t_rr = 35ns, V_F = 0.97V - Near-identical electrical specs; DO-201AD package, same pinout and footprint.	No layout change required; identical mechanical fit and soldering profile; qualified per AEC-Q101 in MUR620H variant.	MUR620 is a direct form-fit-function alternative with validated automotive qualification path if SF64GH is unavailable.

Compared with STTH6S02 and MUR620, the SF64G offers identical V_RRM/I_F/t_rr performance in a cost-optimized DO-201AD package, with lower R_θJL than TO-220 alternatives and proven compatibility in high-volume telecom and industrial adapter designs.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for SF64G?

The SF64G has a V_RRM rating of 200 V, meaning it can reliably block up to 200 volts of reverse voltage in repetitive operation without breakdown. This rating is confirmed in the Absolute Maximum Ratings table on page 2 of the official TSC SF61G–SF68G datasheet (Version G2105), and defines its use in 200V-class power rails such as telecom DC-DC secondaries and industrial 200V inverters.

What is the forward voltage (V_F) of SF64G at 6A and 25°C?

The SF64G exhibits a typical forward voltage of 0.975 V at 6 A and 25°C junction temperature, as specified in the Electrical Specifications table (page 2, Version G2105). This low V_F directly reduces conduction loss and improves thermal performance compared to standard fast recovery diodes, making SF64G especially effective in high-duty-cycle rectification stages.

Is SF64G suitable for automotive applications?

The base SF64G is not AEC-Q101 qualified, but the pin-compatible SF64GH variant is explicitly qualified per AEC-Q101. Engineers designing automotive DC-DC converters or infotainment power supplies should specify SF64GH to meet automotive reliability and qualification requirements - the "H" suffix denotes full qualification, while SF64G remains suited for industrial and commercial applications.

What package type does SF64G use, and what are its key mechanical features?

SF64G uses the DO-201AD axial-leaded package, with cathode polarity indicated by a band, pure tin-plated leads compliant with J-STD-002, and UL 94V-0 flammability-rated molding compound. Its R_θJL is 5°C/W, supporting direct thermal coupling to PCB copper, and it weighs approximately 1.20 g - all confirmed in the Mechanical Data section of the TSC SF61G–SF68G datasheet.

How does SF64G compare to SF63G and SF65G in terms of voltage rating and forward voltage?

SF64G is rated for 200 V V_RRM, positioned between SF63G (150 V) and SF65G (300 V). Its forward voltage is 0.975 V at 6A/25°C - identical to SF61G–SF64G group, while SF65G–SF68G have higher V_F (1.300–1.700 V) due to increased voltage-blocking structure. This makes SF64G optimal for 200V systems needing lowest possible V_F without sacrificing voltage margin.
