Notes
1. In the application, the reference current will be generated by means of a resistor. The given current can be realized
2. I
3. The voltage on TLN can be clamped with respect to GND (positive and negative) with one or two diodes. The clamp
4. In the TZA1020A, pin MIRN is clamped with respect to GND (positive) by means of one diode.
