MCR12LD/LM/LN is the preferred device for half-wave ac control applications such as motor controls, heating controls, and power supplies; or wherever half-wave, silicon gate-controlled devices are needed.
This document provides technical specifications and application information for the MCR12LD, MCR12LM, and MCR12LN silicon controlled rectifiers (SCRs). These devices are reverse blocking thyristors designed primarily for half-wave AC control applications, such as motor controls, heating controls, and power supplies. The series offers a peak non-repetitive surge current capability of 100 Amperes and is housed in a rugged TO-220AB package.
| On-State RMS Current | 12 A |
|---|---|
| Peak Non-repetitive Surge Current | 100 A |
| Operating Junction Temperature Range | -40 to 125 °C |
| Thermal Resistance — Junction to Case | 22 °C/W |
| Package Type | TO-220AB |
The MCR12LD has a rating of 400 Volts, the MCR12LM is 600 Volts, and the MCR12LN is 800 Volts.
The maximum lead temperature for soldering purposes is 260 °C for 1/8” from the case for 10 seconds.
