1N5949APE3/TR12 Application Field and Working Principle

Introduction to 1N5949APE3/TR12 Zener Diode

The 1N5949APE3/TR12 Zener diode is an ideally suited device for use in a wide range of circuits where high voltage protection and regulation is needed. This is a single-diode, voltage regulator type, operating at a constant breakdown voltage of 12 volts. It provides the circuit designer with high level of protection against overloads and damaging overloads.The 1N5949APE3/TR12 Zener diode is a guaranteed 5 watt device, with a maximum reverse power dissipation of 3 watts. This device has an absolute maximum breakdown voltage rating of 12 volts and an absolute maximum surge voltage rating of 20 volts. This Zener diode also exhibits an excellent thermal response time characteristic and is rated for 150 ohms maximum normal forward current.

Application Field of 1N5949APE3/TR12 Zener Diode

The 1N5949APE3/TR12 Zener diode is ideal for use in circuits where high voltage protection and regulation is required. This device can be used for applications such as lighting control circuits, battery-backed power supplies and ground loops. It is particularly useful for motor speed or light intensity control circuits, where the same circuit is used for both protection and regulation.The device is also perfect for use as a voltage regulator since it has a guaranteed breakdown voltage of 12 volts and an absolute maximum breakdown voltage of 20 volts. This Zener diode can also be used in a wide range of low voltage applications such as essential signal conditioning, logic circuits, instrumentation and control loops.

Working Principle of 1N5949APE3/TR12 Zener Diode

The 1N5949APE3/TR12 Zener diode operates by allowing a certain amount of current to flow in reverse through the diode when a certain voltage is applied to it. This is called its “breakdown voltage” and is guaranteed to be 12 volts.When this voltage is reached, the reverse current starts to flow and is limited by the resistance of the diode junction, resulting in a regulated, constant voltage across the diode. This regulator action is beneficial, since it limits the voltage to a constant level which is ideal for providing a stable voltage in circuits.The 1N5949APE3/TR12 Zener diode also has two other terms which describe its characteristics: its “normal forward” current, which is the amount of current allowed to flow through the diode when the voltage does not reach the breakdown voltage, and its “reverse power dissipation”, which is the amount of power that can be dissipated by the diode in the reverse direction.

Conclusion

The 1N5949APE3/TR12 Zener diode is a reliable and efficient device which is perfect for use in low voltage applications such as lighting control circuits and battery-backed power supplies. It has a guaranteed breakdown voltage of 12 volts and an absolute maximum breakdown voltage of 20 volts as well as an excellent thermal response time. Its reverse power dissipation is rated at 3 watts and its normal forward current is rated at 150 ohms.
