For engineers reviewing the SFF2006GH datasheet, SFF2006GH pinout, SFF2006GH application, or SFF2006GH equivalent, key selection criteria include peak reverse voltage (400 V), thermal resistance (2.5 °C/W), AEC-Q101 qualification, UL recognition (E-326243), and dual-die layout for parallel current handling.
Technical Context
This device implements a super fast recovery rectifier architecture optimized for switching-mode power supplies, featuring low VF and trr to minimize conduction and switching losses. Its dual-die construction enables balanced current sharing and improved thermal distribution across the ITO-220AB case.
The SFF2006GH operates over –55°C to +150°C junction temperature range and supports 8.3 ms half-sine surge currents up to 150 A. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2004TV1 | Single-die 400 V/20 A, 30 ns trr, RθJC = 2.0 °C/W, no AEC-Q101 | Lacks automotive qualification; higher trr margin but lower thermal robustness in sustained 20 A operation | Prefer where cost sensitivity outweighs automotive compliance and thermal derating headroom is available |
| VS-20EWH04-M3 | Dual-die 400 V/20 A, 35 ns trr, RθJC = 2.4 °C/W, AEC-Q101 qualified, same ITO-220AB footprint | Identical electrical specs and qualification; differs in lead finish (NiPdAu vs. matte tin) and JEDEC moisture sensitivity level | Drop-in alternative when matte tin plating compatibility with existing reflow profile is confirmed |
Compared with STTH2004TV1 and VS-20EWH04-M3, the SFF2006GH offers identical dual-die layout and AEC-Q101 validation but uses industry-standard matte tin leads - simplifying solder process integration while maintaining 35 ns recovery and 2.5 °C/W thermal performance.

FAQ
What is the peak repetitive reverse voltage rating for SFF2006GH?
The SFF2006GH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is specified per diode in the dual-die structure and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is validated per IEC 60747-2 and aligns with the "06" digit in the marking code SFF2006GH.
Does SFF2006GH require external heatsinking in 20 A continuous operation?
Yes, the SFF2006GH requires heatsinking for 20 A continuous operation. With RθJC = 2.5 °C/W and VF ≈ 1.3 V, power dissipation exceeds 26 W at full load - necessitating a heatsink capable of maintaining case temperature ≤ 75°C. The isolated tab allows direct mounting to a grounded heatsink without electrical isolation components.
Is SFF2006GH pin-compatible with other devices in the SFF200xG series?
Yes, all SFF200xG and SFF200xGH variants share identical ITO-220AB package dimensions, pinout, and terminal assignments. The "x" digit only changes VRRM (50–600 V) and forward voltage (0.975–1.700 V); mechanical and thermal interfaces remain fully interchangeable across the family.
What does the "H" suffix in SFF2006GH signify?
The "H" suffix in SFF2006GH indicates AEC-Q101 qualification. This means the device has passed stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - confirming suitability for automotive under-hood applications such as engine control units and ADAS power supplies.
How is the dual-die configuration of SFF2006GH utilized in circuit design?
The dual-die configuration of SFF2006GH provides two independent anodes sharing one cathode. This enables flexible topologies: parallel connection for 40 A total current, center-tapped transformer rectification, or independent channel rectification in multi-output converters - all within a single ITO-220AB footprint, reducing PCB area and thermal interface complexity.
