Key Features
- 650 V collector-emitter voltage and 20 A continuous collector current (40 A peak) in a compact D²PAK (TO-263AB) SMD package
- Trench gate field-stop technology reduces conduction losses and switching energy for high-efficiency power conversion above 400 V
- Integrated built-in freewheeling diode eliminates the need for an external antiparallel diode, simplifying PCB layout and reducing BOM count
- HB2 high-speed series optimized for switching frequencies up to several tens of kHz in PFC and inverter topologies
Applications
The STGB20H65DFB2 is designed for switch-mode power supplies, PFC boost stages, and single-phase inverter bridges operating from 400 V AC mains where 650 V blocking capability and 20 A continuous current are required. Its trench gate field-stop structure and integrated diode make it ideal for air conditioner compressor drives, solar microinverters, and uninterruptible power supplies (UPS) requiring efficient hard-switching or soft-switching operation. The D²PAK surface-mount package facilitates automated assembly in motor control boards and industrial power modules where heatsink attachment to the PCB is advantageous.

Frequently Asked Questions
What are the critical voltage and current ratings of the STGB20H65DFB2, and how do they map to typical AC mains applications?
The STGB20H65DFB2 is rated at 650 V collector-emitter voltage and 20 A continuous collector current, with a peak rating of 40 A. These specifications make it directly suitable for 230 V AC single-phase or 400 V AC three-phase industrial applications, providing the necessary voltage margin above the rectified bus voltage of approximately 325 V to 560 V.
How does the built-in freewheeling diode in the STGB20H65DFB2 affect circuit design for H-bridge or inverter topologies?
The integrated antiparallel freewheeling diode in the STGB20H65DFB2 eliminates the need for a separate external diode in each switch position of an H-bridge or half-bridge inverter, reducing the discrete component count by at least 1 diode per switch position. This lowers BOM cost, simplifies PCB routing, and decreases parasitic inductance in high-current 650 V switching paths.
Which power conversion topologies are best matched to the STGB20H65DFB2's HB2 high-speed characteristics?
The HB2 series designation indicates optimized performance in hard-switching topologies such as boost PFC converters, single-phase full-bridge inverters, and half-bridge DC-AC stages operating at switching frequencies typically between 16 kHz and 40 kHz. The trench gate field-stop technology delivers reduced turn-off energy (Eoff) at 650 V, which is critical for maintaining high efficiency in motor drive inverters and solar microinverters processing continuous loads of 20 A.
What thermal and package characteristics does the D²PAK (TO-263AB) format provide for the STGB20H65DFB2 in SMT designs?
The D²PAK (TO-263AB) package provides a large exposed copper tab on the bottom that solders directly to the PCB for thermal dissipation, with a junction-to-case thermal resistance (RθJC) typically around 1 °C/W, supporting power dissipation up to approximately 100 W when mounted on a 1 oz copper pour. The surface-mount format suits automated reflow assembly while also allowing a PCB-top heatsink clip for higher continuous power in 650 V, 20 A IGBT applications.
