Key Features
- 100 V reverse voltage rating enables use in high-voltage rectification stages of AC-DC power supplies and industrial power converters
- Low 0.81 V maximum forward voltage reduces conduction losses and heat generation compared to standard rectifier diodes at 8 A forward current
- Low leakage current characteristic minimizes off-state power dissipation in high-voltage hold-up capacitor circuits and output filter stages
- D2PAK surface-mount power package with cathode case connection allows direct PCB mounting with excellent thermal coupling to copper power planes
Applications
The STPS8H100G is used in output rectification stages of switch-mode power supplies operating from 48 V to 100 V input rails, where its low forward voltage reduces heat generation and improves overall conversion efficiency. It serves as a freewheeling diode in motor drive H-bridge circuits and boost PFC stages, where reverse recovery characteristics and low leakage are important for switching losses. The device is also applied in solar panel bypass diode strings and battery charger output stages requiring reliable rectification at up to 100 V and 8 A.

Frequently Asked Questions
What is the maximum reverse voltage of the STPS8H100G?
The STPS8H100G has a maximum reverse voltage rating of 100 V. This allows it to be used in power supply output stages, PFC rectifiers, and motor drive circuits where the reverse voltage across the diode can approach or exceed standard 48 V and 60 V bus levels under transient conditions.
What is the forward voltage drop of the STPS8H100G at rated current?
The STPS8H100G has a maximum forward voltage (VF) of 0.81 V. This relatively low forward drop reduces conduction losses when carrying the rated 8 A forward current, resulting in less power dissipated as heat in the diode and improved overall power supply efficiency compared to standard rectifier diodes.
What package does the STPS8H100G use?
The STPS8H100G is housed in a 3-pin D2PAK (TO-263) surface-mount package with cathode case connection. The D2PAK package provides a large exposed metal tab that solders directly to the PCB copper, enabling efficient heat transfer to the board's thermal plane and eliminating the need for a separate heatsink in many applications.
What does 'low leakage current' mean for the STPS8H100G?
Low leakage current means the STPS8H100G passes very little reverse current when reverse biased at its rated voltage. This reduces standby power losses in circuits where the diode blocks high voltage for extended periods, such as bulk capacitor hold-up circuits in offline power supplies and high-voltage battery protection stages.
Is the STPS8H100G suitable for high-frequency switching applications?
The STPS8H100G is a silicon rectifier diode optimized for low forward voltage and low leakage at high voltage, making it suitable for power frequency and moderate switching frequency applications up to several hundred kHz. For very high switching frequencies above 500 kHz, Schottky diodes with faster recovery characteristics may be more appropriate depending on the specific circuit requirements.
