This article will provide a brief explanation of the application field and working principle of CR08AS-12A-T14#B10.

Application Field

The CR08AS-12A-T14#B10 is a silicon-controlled rectifier (SCR) which is used in general purpose circuits for power management applications. It is suitable for inductive and motor speed control, DC light dimmers, AC motor control, battery chargers, DC motor control, and power conversion circuits.

This SCR can carry up to 12A of current and has a voltage drop of 1.4V. It can be used in high reliable power circuits such as home and industrial equipment and has an operating temperature of -40°C to 85°C.

The package configuration of this SCR is TO-220AB which measures in at 8.1 cm (L) X 14.8 cm (W) X 4.9 cm (H). It provides an easy installation to heat sink and wire solder method.

Working Principle

The basic structure of a CR08AS-12A-T14#B10 SCR consists of two P-type semiconductors and two N-type semiconductors connected in a four-layer structure as illustrated in the figure below.

When no voltage is applied to the gate, no current flows through the device. When a positive voltage is applied to the gate, the NPN transistor is activated and the region between the Anode and the Cathode is forward biased, allowing current to flow in the Anode to Cathode direction. This forward current can be controlled by the gate voltage.

The gate capacitance is very low, allowing the current to switch quickly. The device has a blocking voltage of 800 volts and a forward surge current of 2.5A. This allows the device to be used in applications requiring a high degree of reliability.

Conclusion

Overall, CR08AS-12A-T14#B10 is a sensitive gate, silicon-controlled rectifier (SCR) used for general purpose applications. It has a wide range of applications such as inductive and motor speed control, DC light dimmers, AC motor control, battery chargers, DC motor control, and power conversion circuits. It has a blocking voltage of 800V and a forward surge current of 2.5A, making it suitable for use in high-reliability power circuits.
