Key Features
- 30 A average forward current rating with 100 V reverse voltage enabling high-current DC rectification in power supplies and motor drives
- Maximum 0.565 V forward voltage (VF) delivering lower conduction losses compared to standard silicon rectifiers in efficiency-critical designs
- Isolated TO-220FPAB (R-PSFM-T3) case connection allowing direct mounting to heatsink without electrical insulation pads
Applications
STPS30M100SFP is designed for output rectification in switch-mode power supplies, solar charge controllers, and DC-DC converters where low forward voltage drop is critical to improving efficiency at high currents. The 30 A current rating suits industrial motor drive freewheeling diode positions and UPS battery charger output stages operating at bus voltages up to 100 V. The isolated TO-220FPAB package simplifies thermal management by allowing direct heatsink contact without an insulating washer.

Frequently Asked Questions
What is the forward voltage of STPS30M100SFP and how does it reduce power losses in a 30 A rectifier stage?
At 30 A forward current, the maximum forward voltage of STPS30M100SFP is 0.565 V, compared to 0.7-1.0 V for standard silicon PN diodes. This lower VF reduces conduction loss by roughly (1.0 - 0.565) × 30 A = 13 W per rectifier, a significant efficiency improvement in high-current DC power supplies and battery chargers operating continuously.
Why is the isolated TO-220FPAB package of STPS30M100SFP advantageous in multi-diode heatsink assemblies?
The isolated case (TO-220FPAB) means the metal tab is not electrically connected to any diode terminal, so multiple STPS30M100SFP units can share a single heatsink without individual isolation pads. This simplifies mechanical design, improves thermal conductivity versus adding an insulating washer, and reduces assembly time in 3-phase or bridge rectifier configurations.
For a 100 V bus solar charge controller, how does STPS30M100SFP compare to a 60 V-rated Schottky in reverse voltage margin?
STPS30M100SFP is rated at 100 V reverse voltage, providing a 2x safety margin over a 60 V Schottky when used on a nominal 48 V bus with transient spikes. Solar and battery bus voltages can spike 20-50% above nominal, so the 100 V rating prevents reverse breakdown, while the 30 A current rating handles typical 1-2 kW charge controller output currents.
