7.3.3 Transient Protection

The –16-V to 80-V common-mode range of INA901-SP is ideal for withstanding fault conditions ranging from 12-V battery reversal up to 80-V transients because no additional protective components are needed up to those levels. In the event that INA901-SP exposed to transients on the inputs in excess of their ratings, external transient absorption with semiconductor transient absorbers (Zeners or Transzorbs) are necessary.

Use of MOVs or VDRs is not recommended except when they are used in addition to a semiconductor transient absorber. Select the transient absorber such that it never allows the INA901-SP to be exposed to transients greater than 80 V (that is, allow for transient absorber tolerance, as well as additional voltage because of transient absorber dynamic impedance). Despite the use of internal Zener-type ESD protection, the INA901-SP is not suited to using external resistors in series with the inputs because the internal gain resistors can vary up to ±30%, but are tightly matched (if gain accuracy is not important, then resistors can be added in series with the INA901-SP inputs with two equal resistors on each input).
