STMicroelectronics Thyristor 600 V 8 A TO-92 3-Pin Sensitive Gate SCR P0111MA 1AA3

STMicroelectronics P0111MA 1AA3 is a sensitive gate thyristor (SCR) housed in a compact TO-92 3-pin package. It features a 600 V repetitive peak reverse voltage and can withstand an 8 A surge current, making it ideal for power switching controls in industrial and electronic circuits.

This device is engineered for applications where gate triggering current is limited, such as ground fault circuit interrupters and residual current circuit breakers. It offers reliable operation with a rated average on-state current of 0.5 A and a maximum holding current of 5 mA.

The low gate trigger voltage of 0.8 V and a minimal gate trigger current of 0.025 mA make it highly sensitive, improving efficiency and control in switching circuits.

The peak on-state voltage of 1.95 V ensures minimal power loss during conduction. It is designed for through-hole mounting on standard printed circuit boards with its TO-92 package configuration, featuring 3 pins for electrical connections.

With a maximum operating temperature of 125°C, this thyristor meets typical industrial temperature specifications. It does not carry automotive certifications but is widely used in industrial, domestic, and laboratory electronic applications for robust switching control.

The device is part of the P011xx SCR series by STMicroelectronics, representing a range of sensitive gate thyristors. Key features include its sensitive gate triggering, low leakage currents, and compact packaging. Applications include power control, circuit protection, and switching in semiconductor electronic systems.
