Refer to the 'ZSC31150 High Voltage Protection Description' for specification and detailed conditions

2

Notice temperature profile description in the 'ZSC31150 Dice Package Document' for operation in temperature range > 125 °C

3

Symmetric behavior and identical electrical properties (especially with regard to the low pass characteristic) of both sensor inputs of

the ZSC31150 are required. Unsymmetrical conditions of the sensor and/or external components connected to the sensor input pins of

ZSC31150 can generate a failure in signal operation

4

No measurement in mass production, parameter is guaranteed by design and/or quality observation.
