DESCRIPTION
SOT-223
The UTC MCR08 is a 0.8A SCR, it uses UTC’s advanced
technology to provide customers with sensitive gate trigger current,
etc.
The UTC MCR08 is suitable for line powered consumer
applications such as relay and lamp drivers, small motor controls,
gate drivers for larger thyristors, and sensing and detection circuits.

Notes: 1. VDRM and VRRM for all types can be applied on a continuous basis. Ratings apply for zero or negative gate
voltage; however, positive gate voltage shall not be applied concurrent with negative potential on the
anode. Blocking voltages shall not be tested with a constant source such that the voltage ratings of the
devices are exceeded.
2. Pulse Test: Pulse width≤300μs, Duty cycle≤2%.
3. RGK=1000Ω is included in measurement.
4. RGK is not included in measurement.
