Industrial 109270 Thyristor Silicon Controlled Rectifier

Miller 109270 Silicon Controlled Rectifier (SCR) is an industrial-grade thyristor rated for 300 volts, designed to switch and regulate current in power-electronic circuits through gate-triggered control, suitable for discrete devices or modular power assemblies in industrial environments. The device carries part number 109270 and is packaged in a hockey-puck form factor, a compact disc-shaped package that minimizes space requirements and simplifies integration into tight assemblies. In operation, an SCR conducts when a gate signal is applied and, once triggered, remains on until the current falls below the device’s holding value, enabling reliable, latch-like conduction for rectification and switching across various pulse-width or AC control scenarios. With Miller as the manufacturer, the 109270 provides a clearly defined option for engineers seeking a 300V, low-profile silicon-controlled rectifier in a hockey-puck package for industrial power electronics.
