Microchip Technology JANS1N4954DUS is a high-reliability Zener diode designed for demanding applications. This D-5B package device offers a precise 6.8 V nominal Zener voltage with a tight ±1% tolerance, ensuring stable voltage regulation. With a maximum power dissipation of 5 W and a low impedance of 1 Ohm (Zzt), it effectively manages power in regulated power supplies and voltage clamping circuits. The JANS1N4954DUS features a low reverse leakage of 150 µA at 5.2 V and a forward voltage of 1.5 V at 1 A. Its military-grade qualification (MIL-PRF-19500/356) and wide operating temperature range of -65°C to 175°C make it suitable for aerospace, defense, and industrial control systems. The surface mount SQ-MELF, E package facilitates efficient board assembly.
