STMicroelectronics Sensitive Gate Thyristor SCR 600 V 1.25 A TO-92 Package X0202MA 1BA2

STMicroelectronics X0202MA 1BA2 is a sensitive gate Silicon Controlled Rectifier (SCR) thyristor in a compact TO-92 package, optimized for power switching and control applications requiring low gate trigger currents.

This thyristor features a rated average on-state current of 1.25 A, repetitive peak reverse voltage of 600 V, and an ability to withstand surge currents up to 25 A. Its low maximum gate trigger current of 200 μA makes it ideal for circuits where gate current is limited.

The device offers robust operating temperature range from -40°C to 125°C, ensuring reliable performance in demanding industrial, electronic, and electrical environments.

Typical use cases include ground fault circuit interrupters (GFCI), residual current circuit breakers (RCCB), and other applications requiring sensitive gate triggering and precise power control.

Easy to mount with through-hole TO-92 package. Low gate trigger voltage of 0.8 V enhances triggering efficiency. Designed for efficient power switching with stable holding current of 5 mA. Repetitive peak off-state current at 500 μA provides device stability.

Suitable for use in automation, industrial controls, and power management systems. The package contains the single STMicroelectronics X0202MA 1BA2 Thyristor. Compatible with industrial, laboratory, and manufacturing electronic equipment.
