Product details

Overview

SF1008G from Taiwan Semiconductor is a 600V, 10A super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 1.700V forward voltage at 5A/25°C, and 125A surge capability - deployed in high-frequency switching inverters and DC-DC converters requiring low conduction loss and fast turn-off.

For engineers reviewing the SF1008G datasheet, SF1008G pinout, SF1008G application, or SF1008G equivalent, key selection criteria include V_RRM = 600V, I_F = 10A, t_rr = 35ns, R_θJC = 3.5°C/W, and AEC-Q101 qualification status (SF1008GH variant only).

Technical Context

This device is a single-die, unidirectional super fast rectifier optimized for high-efficiency power conversion above 20kHz. Its 35ns reverse recovery time and low junction capacitance (50pF at 4V) minimize switching losses in hard-switched topologies.

The SF1008G operates with maximum junction temperature of 150°C and thermal resistance of 3.5°C/W from junction to case, enabling direct heatsink mounting without isolation washers in industrial-grade designs.

Key Specifications

V_RRM	600 V - supports DC bus voltages up to 424V RMS in bridge configurations
I_F	10 A continuous - rated for sustained conduction in 100W–200W power stages
t_rr	35 ns - enables operation in 100–500 kHz SMPS without excessive switching loss
V_F	1.700 V @ 5A, 25°C - determines conduction loss of ~8.5W at full load in single-diode path
R_θJC	3.5 °C/W - allows 40°C temperature rise at 10A with 140°C max junction temp
C_J	50 pF @ 4V - limits capacitive coupling noise in high-dv/dt gate-drive environments
I_FSM	125 A @ 8.3ms - withstands inrush currents during cold-start in offline converters

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH10R06DJF	V_F = 1.75V @ 5A, t_rr = 30ns, same TO-220AC package	Lower t_rr but higher V_F; no AEC-Q101 option available	Preferred where faster recovery outweighs conduction loss penalty
VS-10EWH06-M3	V_F = 1.65V @ 5A, t_rr = 40ns, TO-220AC with insulated tab	Lower V_F, slightly slower recovery; includes integrated thermal pad	Selected when lower conduction loss dominates over EMI concerns

Compared with STTH10R06DJF and VS-10EWH06-M3, the SF1008G offers balanced trade-off between V_F and t_rr with documented 3.5°C/W thermal resistance - critical for thermally constrained industrial layouts where heatsink space is limited.

FAQ

What is the maximum junction temperature rating for SF1008G?

The SF1008G has a maximum junction temperature (T_J) of +150°C, validated per JEDEC standards. This rating allows operation in ambient temperatures up to +105°C when mounted on a heatsink providing ≤3.5°C/W thermal resistance. Derating curves in the SF1008G datasheet confirm 10A continuous current remains viable at 125°C case temperature.

Is SF1008G AEC-Q101 qualified?

The SF1008G itself is not AEC-Q101 qualified; only the SF1008GH variant carries that qualification. The "H" suffix denotes automotive-grade screening including extended temperature cycling, high-temperature operating life, and biased HTRB testing. For automotive designs, SF1008GH must be specified explicitly - SF1008G is intended for industrial and commercial applications.

What is the reverse recovery time (t_rr) of SF1008G and how is it measured?

The SF1008G has a typical reverse recovery time (t_rr) of 35ns, measured under conditions of I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A per the manufacturer's test circuit (Fig.6 in the SF1008G datasheet). This value is guaranteed maximum and applies across the full operating temperature range.

Does SF1008G have an insulated tab?

No, the SF1008G uses a standard TO-220AB package with electrically conductive tab connected to the cathode. Insulation (e.g., mica washer or silicone pad) is required when mounting to a grounded heatsink. Unlike TO-220AC variants, the TO-220AB outline does not integrate internal insulation - this is confirmed in the mechanical drawings on page 5 of the SF1008G datasheet.

What is the forward voltage (V_F) of SF1008G at elevated temperature?

The SF1008G exhibits positive temperature coefficient for V_F: at I_F = 5A and T_J = 100°C, V_F rises to approximately 1.85V (vs. 1.700V at 25°C). This behavior is documented in Fig.4 (Typical Forward Characteristics) of the SF1008G datasheet and supports predictable thermal runaway immunity in parallel configurations.
