Some diode manufacturers caution against using the diode tester function in ohmmeters because it could exceed the reverse-voltage and forward-current ratings of sensitive diodes.

Vishay’s single-line VGSOTxx and two-line VGSOTxxC ESD protection diodes offer reverse working voltages from 3.3 V to 36 V.

Unlike ideal diodes with reverse current blocking features, these devices are suitable for applications where energy may return to the input supply.
