STMicroelectronics 100 V 20 A Schottky Diode Through Hole TO-220ABFP STPS20H100CFP

STMicroelectronics STPS20H100CFP is a high-performance Schottky diode designed for power electronics applications requiring reliable rectification and low forward voltage drop. Housed in a TO-220ABFP package, this diode supports through-hole mounting and offers rugged construction with excellent thermal characteristics.

Rated for a maximum continuous forward current of 20 A and withstands peak reverse repetitive voltages up to 100 V, it ensures robust operation in demanding circuits. The device’s low forward voltage drop of 0.59 V minimizes conduction losses, making it energy-efficient for power supply and conversion applications.

The diode features a common cathode configuration with a compact three-pin layout. Its wide operating temperature range from -65°C to 175°C allows usage in harsh industrial and automotive environments where thermal resilience is critical.

With a high surge current capability of 250 A for short durations, it can handle transient currents without damage. The diode's very low peak reverse current of 4.5 μA further improves circuit reliability by reducing leakage currents.

Typical uses include automotive electronics, power supplies, voltage clamping, and general-purpose rectification in semiconductor and discrete device circuits. Its dimensions of 10.4 mm length, 9.3 mm height, and 4.6 mm width facilitate easy PCB layout integration.

This diode features a common cathode configuration to provide efficient performance. The package type is TO-220ABFP suitable for through-hole mounting. Maximum continuous forward current is rated at 20A with a peak reverse repetitive voltage of 100V.

The device supports a maximum operating temperature up to 175°C with minimum operating temperature down to -65°C. Maximum forward voltage drop is 0.59 V, ensuring low power losses. Peak non-repetitive forward surge current can reach up to 250 A.

The diode has 3 pins for connectivity and compact dimensions (10.4mm length, 9.3mm height, 4.6mm width). Peak reverse current is very low at 4.5 microamperes to reduce leakage. This diode is ideal for power and discrete semiconductor applications requiring efficient rectification.
