Ween BT145 Thyristor 800V 16A TO-220AB

The Ween BT145 Thyristor 800V 16A TO-220AB is a planar passivated Silicon Controlled Rectifier (SCR) with a peak repetitive off-state voltage of 800V and an average on-state current of 16A, making it a practical choice for power control and protection circuits.

Overview

The BT145 is housed in a robust TO-220AB (SOT78) plastic package with three pins and a through hole mounting type. Planar passivation is a key feature of this device, enhancing voltage ruggedness and long-term reliability. The thyristor is engineered to manage high surge currents and maintain stable performance under continuous operational stress, with a maximum operating temperature of 125°C.
