BT169D Thyristor 0.8A 400v

The BT169D is a compact thyristor engineered for efficient control of electrical power in circuits requiring up to 0.8 amperes and 400 volts. Its reliable switching characteristics and low gate trigger current make it suitable for a range of industrial and consumer power-regulation tasks where compact size and stable performance are required. Maximum current rating: 0.8 A for controlled current flow. Peak voltage capability: 400 V for moderate-voltage applications. Package: TO-92 configuration enabling simple integration into compact PCB layouts. Fast switching performance to improve circuit responsiveness. Low gate trigger current for reduced drive power and improved energy efficiency. Compared with typical devices in its class, the BT169D offers a balanced combination of voltage tolerance and current capacity while retaining a small footprint. The device’s improved gate sensitivity lowers the required drive energy, which can simplify gate drive design and reduce power loss in the control stage. Its construction and semiconductor design contribute to enhanced thermal stability and durability under routine operating conditions. Engineers can leverage the BT169D in small to medium power control applications such as switching and phase control where a compact TO-92 packaged thyristor with reliable switching and modest voltage and current ratings is appropriate.
