Abstract: An electronic test equipment apparatus includes a power terminal configured to receive power, an interface for a device under test (DUT), at least one power transistor connected in series between the power terminal and the interface for the DUT, and a protection circuit. The protection circuit is configured to: switch on the at least one power transistor, to electrically connect the power terminal to the DUT through the interface as part of a test routine; and subsequently automatically switch off the at least one power transistor after a predetermined delay, to electrically disconnect the power terminal from the DUT regardless of whether the DUT passes or fails the test routine. A voltage clamp circuit for electronic test equipment and corresponding methods of testing devices using such electronic test equipment are also described.
