MTZJT-7216C Discrete Semiconductor Products

The MTZJT-7216C is a single Zener diode, a two-terminal electronic device which conducts in the forward direction when the applied voltage is in the designated breakdown region. It is composed of a junction between two different types of semiconductors, an n-type and a p-type, with the depletion region surrounding the junction. The single Zener diode has many applications, including linear and clipping circuits, bridge rectifiers and reverse voltage protection.

The MTZJT-7216C is a low voltage Zener diode with a breakdown voltage of around 72 volts. It has a high power rating of 3 watts, with its maximum power dissipation at 25°C. It is a surface mount device, with a maximum total height of 1 mm, a lead to lead distance of 4 mm, and a weight of 0.2 mg. Its forward voltage drop is between 0.7V to 1.25V for a range of currents up to 100mA. It also has a high reverse current leakage of up to 5mA.

The working principle of the single Zener diode is based on the Zener effect. When the applied voltage reaches the breakdown voltage, a small current flows in the reverse direction, over the junction, and the diode starts to conduct. As the applied voltage increases, the current increases, up to the maximum rated current of the diode. This current flows through the depletion region, causing the reverse bias to decrease. When the reverse bias drops below the breakdown voltage, the current drops again to a low value.

The MTZJT-7216C has a wide range of applications in several industries. It is commonly used for low voltage linear and clipping circuits, along with voltage stabilizing circuits, in consumer electronics like TVs and radios. It can also be used for surge protection, reverse polarity protection and bridge rectifiers for AC to DC conversion. The single Zener diode has also found its uses for audio equipment, in the form of a voltage regulator circuit.

The single Zener diode is a simple yet versatile device with plenty of applications. The MTZJT-7216C is a low voltage Zener diode with a wide range of uses, and an excellent power rating. It is suitable for linear and clipping circuits, as well as reverse voltage and polarity protection. It can also be used for bridge rectifiers, audio equipment and AC-DC conversion.
