We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop?

A potential difficulty due to diode-turn-on time is that the resultant transitory overshoot voltage across the diode, even when restricted to nanoseconds, can induce overvoltage stress, causing ...

The Model 2520 Pulsed Laser Diode Test System performs electrical characterization of laser diodes in either the chip/bar state or in finished products. According to its manufacturer, the 2520 is ...
