SD11809

Product catalog summary

Overview: The document provides technical specifications for the SD11809, a 1700V 25A Silicon Carbide Schottky Diode, manufactured by Solitron Devices, Inc. It includes details on absolute maximum ratings, electrical specifications, thermal and mechanical characteristics, and applications.

Absolute Maximum Ratings: The diode has a maximum D.C. reverse voltage, repetitive peak voltage, surge peak reverse voltage, and DC blocking voltage of 1700V. It supports a DC forward current of 25A at 25°C and 125°C, with a repetitive peak forward current of 57A at 125°C. The non-repetitive forward surge current is 117A at 25°C and 88A at 150°C. Power dissipation is 66W at 25°C and 21W at 125°C. The maximum case temperature is 175°C, and the maximum junction temperature is 225°C. The operating and storage temperature range is -55°C to +210°C, with a lead temperature of 260°C for 10 seconds.

Applications: The diode is suitable for aerospace, high-efficiency converters and motor drives, and power supplies.

Key Features: The diode features no reverse or forward recovery, near-zero switch loss, temperature-independent switching behavior, a 200°C operating temperature, an isolated case, and a hermetic package. It offers TX, TXV, and space-level screening.

Benefits: The diode allows for parallel devices without thermal runaway, higher efficiency, smaller heat sinks, and is ideal for extreme environment applications.

Electrical Specifications: The typical DC blocking voltage is 1700V. Forward voltage varies with temperature: 1.5V at 25°C, 2.5V at 175°C, and 1.4V at -55°C. Reverse current is 20µA at 25°C and 120µA at 175°C. Total capacitive charge is 225nC, and total capacitance varies with frequency and voltage.

Thermal and Mechanical Characteristics: The thermal resistance from junction to case is to be determined. The diode weighs 8.2g.

Pin Description: Pin 1 is the cathode, and pin 3 is the anode.

Schematic and Package Outline: The document includes detailed schematic and package outline dimensions for the TO-258-3L package.
