Product details

Overview

SFF1007G from Taiwan Semiconductor is a 10A, 500V super fast rectifier diode in ITO-220AB package, featuring 1.700V forward voltage at 5A/25°C, 35ns reverse recovery time, and 50pF junction capacitance per diode - deployed in high-frequency DC-DC converters and freewheeling paths where low switching loss and thermal robustness are critical.

For engineers reviewing the SFF1007G datasheet, SFF1007G pinout, SFF1007G application, or SFF1007G equivalent, key selection criteria include its 500V V_RRM, 125A I_FSM, 2°C/W R_θJC, AEC-Q101 qualification option (SFF1007GH), and dual-die configuration enabling parallel-ready thermal management in automotive and industrial power stages.

Technical Context

The SFF1007G implements a super fast recovery silicon PN junction optimized for switching-mode power supplies operating above 20kHz. Its 35ns trr and 1.700V VF at 5A reflect trade-offs favoring reduced reverse recovery charge over ultra-low conduction loss - suitable for hard-switched topologies requiring predictable turn-off behavior.

Thermally, the ITO-220AB package delivers 2°C/W junction-to-case resistance with matte tin-plated leads compliant to J-STD-002, supporting direct heatsink mounting at ≤0.56 N·m torque. The device operates from –55°C to +150°C junction temperature and meets UL 94V-0 and halogen-free (IEC 61249-2-21) requirements.

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	600V V_RRM, 1.75V V_F @ 5A, 30ns t_rr, TO-220AC package (non-insulated tab)	Higher voltage margin but no AEC-Q101 option; requires external insulation for heatsink mounting	Preferred when 600V blocking is needed and automotive qualification is not required
IXYS MUR1060CT	600V V_RRM, 1.7V V_F @ 5A, 60ns t_rr, TO-220AB package, dual common-cathode configuration	Slower recovery increases switching loss above 100kHz; common-cathode layout differs from SFF1007G's single-diode pinout	Selected for cost-sensitive 50–100kHz applications where trr < 40ns is not mandatory

Compared with STTH10R06DJF and IXYS MUR1060CT, the SFF1007G offers tighter trr tolerance (35ns vs. 30/60ns), AEC-Q101 availability, and ITO-220AB insulation - making it optimal for automotive-grade, high-frequency, thermally constrained rectification where isolation and transient robustness are prioritized over absolute lowest V_F.

FAQ

What is the maximum junction temperature rating for the SFF1007G?

The SFF1007G has a maximum junction temperature (T_J) of +150°C, with operational range from –55°C to +150°C. This rating enables reliable use in high-ambient environments such as engine compartments or enclosed industrial enclosures. Thermal design must maintain junction temperature below this limit using the specified 2°C/W R_θJC and appropriate heatsinking. The SFF1007G datasheet confirms this value under Absolute Maximum Ratings.

Is the SFF1007G pin-compatible with other devices in the SFF1001G–SFF1008G family?

Yes, all SFF1001G–SFF1008G devices share identical ITO-220AB package dimensions, pinout, and thermal footprint - Anode (Lead 1), Cathode (Lead 2), and electrically connected metal tab. This allows voltage-tiered substitution (e.g., SFF1007G ↔ SFF1006G) without PCB changes, provided V_RRM, V_F, and t_rr meet circuit requirements. The SFF1007G marking code is laser-etched on the device body per standard practice.

Does the SFF1007G have AEC-Q101 qualification?

The base SFF1007G is not AEC-Q101 qualified; however, the variant SFF1007GH is fully AEC-Q101 qualified per Version M2105 documentation. The "H" suffix denotes automotive-grade screening including temperature cycling, mechanical shock, and humidity testing. For automotive applications requiring qualification, SFF1007GH must be specified - the SFF1007G itself is intended for industrial and commercial use.

What is the reverse recovery time (t_rr) test condition for the SFF1007G?

The SFF1007G reverse recovery time is measured at I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A, per the manufacturer's Electrical Specifications table. This standardized condition ensures consistent comparison across super fast rectifiers. The typical t_rr is 35ns, with no maximum specified - confirming performance consistency within the SFF1007G production lot. This value is validated in the Characteristics Curves section (Fig.6).

How does the dual-die configuration of the SFF1007G affect its thermal and electrical performance?

The SFF1007G uses dual-die construction within a single ITO-220AB package to improve current sharing uniformity and reduce localized thermal hotspots. Electrically, it functions as a single 10A/500V rectifier; thermally, the dual die spreads power dissipation across the metal tab, enhancing effective R_θJC stability under sustained load. This architecture directly supports the SFF1007G's 125A I_FSM rating and 150°C T_J limit without derating.
