Notes: 1. Tested with pulses tp= 20 ms.
2. Valid provided that leads at a distance of 8mm from body are kept at ambient temperature.
3. The ZPD1 is a silicon diode with operation in forward direction. Hence, the index of all parameters should
be “F” instead of “Z”. Connect the cathode electrode to the negative pole.
4. 15 volts ±2% available upon special request as part number ZPD15C.
