EMZ7T2R Working Principle

The EMZ7T2R contains six independent NPN transistors, which can be used in various combinations to suit the requirements of any particular circuit. The device is designed to operate in the common base circuit, however, the transistors can be configured in the common emitter or common collector circuit. In the common base configuration, the base of the transistor is connected to a voltage source and the emitter is grounded. In this configuration, the emitter to base voltage (Veb) can be varied, allowing the collector current to be adjusted. The amount of collector current is then regulated by the amount of base current supplied.

The EMZ7T2R is designed to operate from a minimum of 4V to an absolute maximum of 16V. It is also designed to provide a high gain, low noise and fast switching speed, making it suitable for applications requiring low power dissipation and fast response times. The EMZ7T2R is able to operate at temperatures ranging from -55°C to +125°C, making it suitable for a wide range of operating environments.

Conclusion

The EMZ7T2R is a surface mount transistor array ideal for use in applications requiring very low power dissipation. Its ability to operate at a wide temperature range, along with its small footprint size, make it a popular choice for portable and hand-held devices. The EMZ7T2R has a wide range of uses including switching, amplifying, and providing logic level control, making it suitable for linear and digital applications alike.
