<div class="diodes-zener-single"><p>The ZMM5243B-13 is a voltage reference diode that goes by the nickname Zener Diode. The ZMM5243B-13 is a Zener diode with a forward voltage drop of 0.7V and a reverse rated voltage between 8-13V. The ZMM5243B-13 is designed for use in low voltage applications. The ZMM5243B-13 is especially useful in applications where a reference voltage is required for voltage stabilization and protection circuits.</p><p>The ZMM5243B-13 is a silicon planar epitaxial type designed for use in low voltage operations. It has a cathode connection with a maximum power dissipation rating of 500mW. The ZMM5243B-13 is available in SOT-23 and SOT-343 packages.</p><p>The ZMM5243B-13 application field includes electronic metering, radio communication, industrial controls and computer peripherals. It is also used in consumer electronics, automotive electronic systems, voltage adjustable power supplies and voltage stabilization circuits.</p><p>The ZMM5243B-13 working principle is based on the principles of reverse biasing. The reverse voltage on the diode causes a current known as the reverse saturation current to flow. The reverse saturation current remains relatively constant over a wide range of reverse voltage called the Zener breakdown voltage. This Zener breakdown voltage is the reverse voltage at which the diode breakdowns and allows for the control of current.</p><p>The ZMM5243B-13 diode also has two other useful operating modes, namely avalanche mode and dynamic resistance mode. In avalanche mode, the current flow through the diode increases exponentially when the applied voltage is greater than the reverse breakdown voltage. This attractive feature of the ZMM5243B-13 makes it suitable for use in voltage regulation applications.</p><p>The dynamic resistance mode of the ZMM5243B-13 diode is primarily used in applications requiring protection against transient over-voltage conditions. In this mode, the diode provides low dynamic resistance and fast dynamic switching. This feature makes the ZMM5243B-13 suitable for use in voltage regulation or voltage protection circuits.</p><p>In summary, the ZMM5243B-13 is a versatile voltage reference diode ideal for low voltage applications. It is designed for use in electronic metering, radio communication, industrial controls, computer peripherals, consumer electronics, automotive electronic systems, voltage adjustable power supplies, voltage stabilization circuits and more. The ZMM5243B-13 is also useful for providing protection against transient over-voltage conditions through its dynamic resistance mode.</p></div>
