6.3.2 Reverse-Voltage Protection

The XTR106 low compliance rating (7.5V) permits the use of various voltage protection methods without compromising operating range. Figure 6-6 shows a diode bridge circuit which allows normal operation even when the voltage connection lines are reversed. The bridge causes a two diode drop (approximately 1.4V) loss in loop-supply voltage. This results in a compliance voltage of approximately 9V—satisfactory for most applications. If a 1.4V drop in loop supply is too much, a diode can be inserted in series with the loop supply voltage and the V+ pin, as shown in Figure 7-6. This protects against reverse output connection lines with only a 0.7V loss in loop-supply voltage.

(1) 36V Zener diode, such as 1N4753A or P6KE39A. Use lower-voltage Zener diodes with loop power-supply voltages < 30V for increased protection.
