Taiwan Semiconductor Corporation SF2006G

Overview

SF2006G from Taiwan Semiconductor is a 20A, 400V super fast recovery rectifier diode in TO-220AB package, featuring 35ns reverse recovery time, 1.300V forward voltage at 10A/25°C, and 150A surge capability - deployed in switching-mode DC-DC converters and freewheeling paths in industrial power supplies.

For engineers reviewing the SF2006G datasheet, SF2006G pinout, SF2006G application, or SF2006G equivalent, key selection criteria include V_RRM = 400V, I_F = 20A, t_rr = 35ns, R_θJC = 2.5°C/W, and AEC-Q101 qualification availability (SF2006GH variant), critical for high-efficiency 48V–400V power conversion designs.

Technical Context

The SF2006G integrates dual die configuration in a single TO-220AB package with common-cathode arrangement, enabling bidirectional conduction control in bridge or dual-switch topologies. Its 35ns t_rr and low Q_rr minimize switching losses during hard-commutation in 50–200kHz SMPS stages.

Thermal performance is defined by R_θJC = 2.5°C/W and T_J(max) = 150°C, supporting continuous 20A operation with heatsink mounting (torque ≤ 0.56 N·m). Reverse leakage remains ≤400 µA at 125°C, ensuring stable blocking under elevated ambient conditions.

Key Specifications

Pinout & Package

Equivalent & Alternatives

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

Compared with STTH2004TV and MUR2040CT, the SF2006G delivers balanced performance: 35ns t_rr meets mid-frequency SMPS needs without premium cost, while its dual-die TO-220AB layout offers unique integration for dual-path designs not supported by single-die alternatives.

Availability

SF2006G is available at Aetrix Electronics and suitable for industrial DC-DC converters, automotive on-board chargers, and telecom rectifier modules requiring stable component supply, long-term lifecycle assurance, and RoHS/halogen-free compliance.

Supply support for SF2006G includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and power discrete manufacturer headquartered in Hsinchu, Taiwan, serving industrial, computing, and automotive markets since 1979.

The SF2001G–SF2008G series targets high-efficiency, high-reliability power conversion systems - specifically engineered for cost-sensitive yet thermally demanding applications where super fast recovery, robust surge capability, and AEC-Q101 qualification (H-grade) are decisive.

FAQ

What is the maximum junction temperature rating for SF2006G?

The SF2006G has a maximum junction temperature (T_J(max)) of +150°C, verified per absolute maximum ratings table. This allows continuous 20A operation with appropriate heatsinking and case temperature monitoring. Derating begins above 75°C case temperature, as shown in Fig.1 Forward Current Derating Curve. The SF2006G must not be operated beyond this limit to ensure reliability and avoid parametric shift.

Is SF2006G pin-compatible with other devices in the SF200xG family?

Yes, all SF2001G–SF2008G devices share identical TO-220AB mechanical outline, pin assignment (Anode1–Cathode–Anode2), and mounting torque specification (≤0.56 N·m). Voltage rating differences (50V–600V) do not affect physical compatibility. However, electrical substitution requires verification of V_RRM, V_F, and t_rr suitability for the target circuit's stress profile.

Does SF2006G meet automotive qualification standards?

The base SF2006G is not AEC-Q101 qualified; however, the SF2006GH variant - indicated by "H" suffix in ordering code - is fully AEC-Q101 qualified and tested per stress test conditions including temperature cycling, HTSL, and unbiased HAST. Automotive users must specify SF2006GH explicitly to receive qualified units.

What is the reverse recovery time measurement condition for SF2006G?

The SF2006G reverse recovery time (t_rr) is specified as 35ns maximum under the condition: I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A, with test circuit per Fig.6. This reflects real-world hard-switching behavior in SMPS freewheeling paths. Data is valid at T_J = 25°C; t_rr increases moderately at elevated junction temperatures.

How does the dual-die configuration of SF2006G impact PCB layout?

The SF2006G's dual-die common-cathode structure allows two independent anode connections sharing one cathode terminal - enabling compact dual-output rectification or interleaved freewheeling without external parallel diodes. Layout benefits include reduced trace inductance between cathodes, simplified thermal pad design, and elimination of mismatch-induced current imbalance seen in discrete paralleling.
