  • The SPT01-335 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 offering two connections for PNP or NPN sensors as shown in and Figure 9.
    Thanks to high performance ST technology, the SPT01-335 protects the proximity sensor to the highest level compliant with IEC 61000-4-2, IEC 61000-4-4 and IEC 60947-5-2 / IEC 61000-4-5 standards.

    Key Features

    • Triple diode array for power bus protection, switch protection and reverse blocking protection
    • Flexible connection for NPN low side or PNP high side sensor configuration
    • 6 V to 36 V supply voltage range
    • Stand-off voltage: 36 V
    • Minimum breakdown voltage VBR: 38 V
    • 8/20 μs 2A maximum clamping voltage: 46 V
    • Direct sensor switches current: 300 mA
    • Blocking diode drop forward voltage VF: 1 V at 300 mA
    • Blocking diode maximum 10 ms square pulse current IFSM: 1 A
    • Ambient temperature: -40 °C to +100 °C
    • QFN3x3-6L 1 mm flat package: 3x3 mm
    • Voltage surge: EN 60947-5-2 or IEC 61000-4-5 with RCC = 500 Ω: ±1 kV
    • Electrostatic discharge ESD, IEC 61000-4-2: ± 8 kV in contact, ± 15 kV in air
    • Electrical transient immunity, IEC 61000-4-4: ±2 kV
