Product details

Overview

SF1005G from Taiwan Semiconductor is a 10A, 400V super fast rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 1.30V forward voltage at 5A/25°C, and dual-die construction for high surge capability. It serves as a primary output rectifier in high-frequency DC-DC converters requiring low conduction loss and fast switching.

For engineers reviewing the SF1005G datasheet, SF1005G pinout, SF1005G application, or SF1005G equivalent, key selection criteria include its 400V V_RRM, 125A I_FSM, 3.5°C/W R_θJC, AEC-Q101 qualification option (SF1005GH), and TO-220AB thermal/mechanical compatibility with standard heatsink mounting.

Technical Context

This super fast rectifier uses epitaxial planar construction with optimized carrier lifetime control to achieve 35ns trr while maintaining low VF and high I_FSM. Its dual-die configuration enables symmetrical current sharing and enhanced thermal distribution across the TO-220AB case.

The device operates over -55°C to +150°C junction temperature range, supports 0.56 N·m mounting torque, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements - critical for automotive and industrial power supply designs.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for SF1005G?

The SF1005G has a V_RRM of 400 V, confirmed in the Absolute Maximum Ratings table. This value defines the highest reverse voltage the device can block repeatedly without breakdown and is strictly assigned to SF1005G - distinct from SF1004G (200V) and SF1006G (500V) in the same family.

Is SF1005G AEC-Q101 qualified?

The base SF1005G is not AEC-Q101 qualified, but the variant SF1005GH is explicitly designated as AEC-Q101 qualified per the Ordering Information table. The "H" suffix denotes qualification, and both share identical electrical and thermal specifications except for the added automotive reliability testing.

What is the forward voltage (V_F) of SF1005G at rated current?

SF1005G exhibits a typical forward voltage of 1.30 V at 5A and 25°C, as specified in the Electrical Specifications table. This value applies specifically to SF1005G and SF1006G; lower-voltage variants (e.g., SF1001G–SF1004G) show 0.975 V, while higher-voltage versions reach 1.70 V.

Does SF1005G have a dual-die configuration?

Yes, SF1005G uses dual-die construction as stated in the KEY PARAMETERS section. This architecture improves current sharing, thermal distribution, and surge current handling compared to single-die TO-220 rectifiers, and is consistent across all SF1001G–SF1008G variants.

What is the junction-to-case thermal resistance (R_θJC) of SF1005G?

The SF1005G has a typical R_θJC of 3.5°C/W, measured from junction to the center tab (cathode), as listed in the Thermal Performance table. This value enables accurate thermal modeling when mounted to a heatsink using the recommended 0.56 N·m torque.
