The Motorola IN759A Zener Diode is a military-grade component designed for use in various electronic applications that require voltage regulation or protection against voltage surges. This diode, specifically identified as Military Specification MIL-Z-51.5, is manufactured by Motorola Solutions, a reputable name in the electronics industry.
The Motorola IN759A Zener Diode is a voltage regulator that maintains a constant voltage level by releasing excess current when the input voltage exceeds a certain value. It features a zener material, typically made of cadmium sulfide, which provides a stable voltage reference. The diode comes in a TO-56 package, which is a standard rectangular case with a flange for heat sinking.
This military-specified zener diode is designed to operate over a wide temperature range, from -55 C to 125 C, making it suitable for use in harsh environments. It also features a high power rating of 1 watt, which allows it to handle a significant amount of electrical current.
The Motorola IN759A Zener Diode is tested to meet the stringent requirements of Military Specification MIL-Z-51.5. This specification outlines the electrical, mechanical, and environmental requirements for zener diodes used in military equipment. The diode undergoes rigorous testing to ensure its reliability, stability, and durability under various conditions.
The diode has a voltage rating of 7.5 volts, with a maximum power dissipation of 1 watt. Its reverse breakdown voltage is 7.2 volts, which is the voltage at which the diode begins to conduct current in the reverse direction. The diode also has a maximum forward current of 1.25 amps and a maximum reverse voltage of 10 volts.
In summary, the Motorola IN759A Zener Diode is a high-performance, military-grade component designed for use in voltage regulation and voltage surge protection applications. Its wide temperature range, high power rating, and rigorous testing to meet military specifications make it an ideal choice for applications that require reliable and stable voltage regulation in challenging environments.
