MCR8/D is a reverse blocking thyristor designed primarily 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.
The MCR8M and MCR8N are silicon controlled rectifiers (SCRs) designed for half‑wave AC control applications such as motor and heating controls. They feature a rugged TO‑220AB package, high surge capability, and reliable glass‑passivated junctions.
Key specifications include a blocking voltage of 600‑800 V, 8 A RMS on‑state current, and thermal resistance values that support operation up to 125 °C junction temperature.
| Blocking Voltage | 600 V to 800 V |
|---|---|
| On‑State RMS Current | 8 A RMS at 80 °C |
| Thermal Resistance – Junction to Case | 22 °C·W |
| Thermal Resistance – Junction to Ambient | 62.5 °C·W |
| dv/dt Rating | 100 V/µs |
The devices can block voltages from 600 V up to 800 V.
Both parts are rated for 8 A RMS on‑state current at 80 °C.
Junction‑to‑case resistance is 22 °C·W and junction‑to‑ambient resistance is 62.5 °C·W.
