The ZMM5236B-13 is a single zener diode that can be used in many applications. It is a low-leakage, high-stability zener diode with a 5.6 Volt zener voltage and a double-layer integrated resistive network for impedance matching and thermal stabilization. The ZMM5236B-13 is intended for use in circuit designs where low leakage, superior stability, and reliable operation are required.

Application Field

The ZMM5236B-13 can be used in a variety of applications wherein low leakage, superior stability, and reliable operation are desired. This diode can be used as a clamp in high-current DC applications, as a voltage reference in AC-level control circuits, and as a voltage comparator in AC-level control circuits. It can also be used to bridge circuit breaks in circuits, provide temperature correction in high-frequency oscillator circuits, and as a protection device in power supply circuits.

Working Principle

The basic working principle of the ZMM5236B-13 zener diode is structure, characterized by an N-type semiconductor and a P-type semiconductor. This diode has a double-layer integrated resistive network. The data sheet describes this network as capable of providing impedance matching and thermal stabilization. The diode can operate in either single or split anode configurations and is capable of dissipating up to 500 mW.

During normal operation, a zener diode acts as an ideal voltage source providing a constant voltage output. The voltage output is determined by the breakdown voltage of the diode. A voltage drop occurs across the diode when the reverse voltage across it exceeds the breakdown voltage. For the ZMM5236B-13, the threshold of breakdown is 5.6 volts. At this point, current begins to flow through the diode, instead of the regular mode of operation.

When the voltage exceeds this threshold of breakdown, the circuit enters an avalanche region. At this point, the voltage across the diode is limited by its zener saturation current, also known as zener current. This current is determined by the breakdown voltage, the temperature of the junction, and the height of the barrier. As a result, this current limits the reverse voltage across the diode to the breakdown voltage.

When the applied voltage source is reversed, the diode works in the normal mode of operation. In this mode, no current passes through the diode, and the voltage just follows the source. As the source is reversed, the voltage across the diode follows the source and the forward current also follows it.

The ZMM5236B-13 is also equipped with an integrated resistive network. This network consists of two layers stacked one over the other. This helps to impedance-match the zener and provides a controlled temperature variation for better performance in AC and high-frequency circuits. It can also serve to reduce the leakage current and increase the overall stability of the diode.

The ZMM5236B-13 can be used in a variety of applications in order to achieve different results. By using it in combination with other components, it can be used for power supply circuits, voltage reference and clamping, voltage level sensing and comparator circuits, and temperature compensation circuits. Its low leakage, its temperature stabilization network, and its controlled voltage characteristics make it well suited for these kinds of applications.
