UTC MCR101 Sensitive Gate Silicon Controlled Rectifier Datasheet
The UTC MCR101 is a sensitive-gate silicon controlled rectifier supplied in a plastic TO-92 package. The document describes it as a PNPN device intended for high-volume, line-powered consumer applications including relay and lamp drivers, small motor controls, gate drivers for larger thyristors, and sensing and detection circuits. It lists features such as a sensitive gate, blocking voltage to 600 V, 0.8 A RMS on-state current at 80°C, 10 A surge current capability, and 20 V/µs minimum dV/dt immunity.
Ordering information covers MCR101 variants in TO-92 with gate, anode, and cathode pins, including Pb-free MCR101L versions and peak-voltage suffixes -4 (200 V), -6 (400 V), and -8 (600 V). The datasheet also provides absolute maximum ratings, thermal data, electrical characteristics, a voltage-current characteristic section, classification of IGT ranks, and typical characteristic curves.
