Motorola Thyristor Device Data is a document about half-wave AC control applications, primarily designed for motor controls, heating controls, and power supplies, or wherever half-wave, silicon gate-controlled devices are needed. Its features include blocking voltage up to 800 volts, an on-state current rating of 12 amperes RMS, high surge current capability of 100 amperes, etc.
This Motorola semiconductor technical data sheet covers the MCR12 series SCRs: MCR12D, MCR12M and MCR12N. It describes devices designed primarily for half-wave ac control applications such as motor controls, heating controls and power supplies.
The document lists maximum ratings, thermal characteristics and electrical characteristics, including blocking voltage to 800 volts, a 12 ampere RMS on-state current rating and a 100 ampere surge current capability. It also gives TO-220AB package dimensions for Case 221A–06, Style 3.

It is designed primarily for half-wave ac control applications such as motor controls, heating controls and power supplies.
The MCR12D is rated 400 V, the MCR12M 600 V and the MCR12N 800 V peak repetitive off-state voltage.
The devices use the industry-standard TO-220AB package, Case 221A–06, Style 3.
The on-state RMS current rating is 12 amperes.
