Shockley diodes are curious devices, but rather limited in application. Their usefulness may be expanded, however, by equipping them with another means of latching. In doing so, each becomes true amplifying devices (if only in an on/off mode), and we refer to these as silicon-controlled rectifiers or … Ver mais If an SCR’s gate is left floating (disconnected), it behaves exactly as a Shockley diode. It may be latched by breakover voltage or by exceeding the critical rate of voltage … Ver mais A rudimentary test of SCR function, or at least terminal identification, may be performed with an ohmmeter. Because the internal connection between gate and cathode is a single … Ver mais If the SCR fails to latch, the problem may be with the load and not the SCR. A certain minimum amount of load current is required to hold the SCR latched in the “on” state. This minimum current level is called the holding … Ver mais “Normal” SCRs, lacking this internal resistor, are sometimes referred to as sensitive gate SCRs due to their ability to be triggered by the slightest positive gate signal. The test circuit for an SCR is both practical as a … Ver mais WebAs a result, the SCR with high failure current and high holding voltage are desired. Adding several diodes to the SCR [1] or stacking the SCRs [2] are solutions to increase the SCR’s holding voltage, but too many devices are needed to achieve high holding voltage since the intrinsic holding voltage of SCR is only ∼2 V in modern processes.
