  • The SPT02 is specifically designed for the protection of 24 V proximity sensors. It implements the reverse polarity and the overvoltage protection of the sensor power supply and the power switch overvoltage protection.

    It provides a very compact and flexible solution.
    Thanks to high performance ST technology, the SPT02 protects the proximity sensor to the highest level compliant with IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 standards.

    Key Features

    • Double diode array for switch protection and reverse blocking protection
    • 6 V to 36 V supply voltage range
    • Minimum breakdown voltage VBR: 38 V
    • 8/20 μs 2 A maximum clamping voltage: 46 V
    • Blocking diode drop forward voltage VF: 1.1 V at 300 mA
    • Blocking diode maximum 10 ms square pulse current IFSM: 3 A
    • Ambient temperature: -40 °C to +100 °C
    • μQFN 2L 0.8 mm flat package
    • Complies with following standards
      • Voltage surge: IEC 61000-4-5, RCC= 500 Ω, ±1 kV
      • Electrostatic discharge, IEC 61000-4-2:
        • ±8 kV contact discharge
        • ±15 kV air discharge
      • Electrical transient immunity: IEC 61000-4-4: ±2 kV
    • Benefits
      • Compliant for interface with logic input type 1, 2 and 3 IEC 61131-2 standard
      • Highly compact with integrated power solution in SMD version
