Product details

Overview

SF13G R0G from Taiwan Semiconductor is a 150 V, 1 A super fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 1 A and 25°C, and 30 A surge current capability; used in DC-DC converters and switching-mode inverters for efficient freewheeling and flyback paths.

For engineers reviewing the SF13G R0G datasheet, SF13G R0G pinout, SF13G R0G application, or SF13G R0G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), forward voltage drop, thermal resistance (R_θJL = 20°C/W), junction capacitance (20 pF), and AEC-Q101 qualification status where applicable.

Technical Context

The SF13G R0G is a single-die, planar epitaxial silicon rectifier optimized for high-speed switching with low stored charge. Its 35 ns trr and 20 pF junction capacitance enable operation in high-frequency power supplies up to several hundred kHz.

Designed for surface-mount–compatible through-hole assembly, it operates across –55°C to +150°C junction temperature range, with 80°C/W junction-to-ambient thermal resistance and pure tin-plated leads compliant with J-STD-002 solderability standards.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L06S	V_RRM = 600 V, V_F = 1.05 V @ 1 A, t_rr = 30 ns, DO-204AL	Higher voltage rating suits 400 V bus designs; slightly higher V_F increases conduction loss at 1 A	Select when 600 V blocking is required; verify layout compatibility with identical DO-41 footprint
ON Semi MUR115	V_RRM = 150 V, V_F = 0.93 V @ 1 A, t_rr = 35 ns, DO-41	Near-identical electrical specs; not AEC-Q101 qualified; different thermal resistance (R_θJA = 75°C/W)	Drop-in alternative where automotive qualification is not required; same pinout and mounting

Compared with STTH1L06S and MUR115, the SF13G R0G offers balanced 150 V/1 A performance with verified AEC-Q101 availability in H-suffix versions, tighter V_F consistency at 25°C, and halogen-free compliance aligned with modern industrial sourcing policies.

FAQ

What is the maximum junction temperature rating for SF13G R0G?

The SF13G R0G has a maximum junction temperature (T_J) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in enclosed industrial environments and under moderate PCB heating. Thermal design must account for R_θJL = 20°C/W and R_θJA = 80°C/W to ensure the SF13G R0G stays within limits under full 1 A load at elevated ambient temperatures.

Does SF13G R0G have AEC-Q101 qualification?

The base SF13G R0G part is not AEC-Q101 qualified; however, the SF13GH variant (with "H" suffix) is explicitly qualified per AEC-Q101 Rev D for automotive underhood applications. The R0G suffix indicates reel packaging (5,000 pcs/tape), not qualification status. Always verify ordering code suffixes-SF13GH R0G-not SF13G R0G-for automotive-grade use.

What is the reverse recovery time (t_rr) specification for SF13G R0G?

The SF13G R0G has a maximum 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 value is confirmed in the official Taiwan Semiconductor H2104 datasheet and enables efficient operation in switching power supplies operating above 200 kHz without significant switching loss penalties.

How does the forward voltage (V_F) of SF13G R0G compare to similar 150 V rectifiers?

The SF13G R0G specifies a typical forward voltage of 0.95 V at 1 A and 25°C, which is competitive with industry benchmarks like ON Semi's MUR115 (0.93 V) and slightly lower than STTH1L06S (1.05 V). Its V_F remains stable across temperature, contributing to predictable conduction loss in thermally varying environments where the SF13G R0G is deployed.

What package type and marking does SF13G R0G use?

SF13G R0G uses the DO-204AL (DO-41) axial-leaded plastic package with cathode indicated by a painted band. Marking on the device reads "SF13G", followed by "G" (green compound), date code (YWW), and factory code (F). Lead finish is pure tin, certified solderable per J-STD-002, and compliant with RoHS and halogen-free standards.
