VOLTAGE REGULATOR

Manufacturer: Microchip Technology

Categories: Single Zener Diodes

Quality Control: Learn More

Microchip Technology JANS1N4478DUS is a precision Zener diode designed for demanding applications requiring stable voltage regulation. This military-grade component offers a nominal Zener voltage of 36 V with a tight ±1% tolerance, ensuring consistent performance across various operating conditions. With a maximum power dissipation of 1.5 W and a low reverse leakage of 50 nA @ 28.8 V, it is suitable for applications where efficiency and reliability are paramount. The JANS1N4478DUS features a low impedance of 27 Ohms (Max) at its Zener voltage and is supplied in a compact SQ-MELF, A (D-5A) surface mount package. Its robust construction and MIL-PRF-19500/406 qualification make it ideal for use in aerospace, defense, and high-reliability industrial systems. The operating temperature range of -65°C to 175°C further underscores its suitability for extreme environments.
