Transient Suppression Circuit

Sensitive electrical components can be given limited protection against excessive voltage or current, especially during testing, by providing a dual- polarity transient suppression circuit to prevent electrostatic charge build-up.

Referring to Fig. 1, a signal Line 1 to component 2, such as a module, is connected to ground through a pair of parallel, oppositely poled diodes 3, 4 in series with a current-limiting resistor 5.

Additional diode pairs 6 can be added in the circuit to establish different desired thresholds, as indicated by diode pair 7, 8 shown in phantom. Other thresholds can also be established by using Zener diodes 9 in series, either alone or with diodes 3, 4, as shown in Fig. 2.

These circuits enable static protection, without power supply voltages or modification of test equipment. Furthermore, no degradation of high frequency testing occurs.
