?The 1SMA4736A Zener Diodes SMA (DO-214AC) RoHS manufactured by LG Electronics is a type of diode which offers a precise zener voltage with high temperature stability. It has a reverse standby current of less than 1µA and its power dissipation of 500mW guarantees its excellent power dissipation capability. The device has an extremely low noise for excellent noise performance. The high peak current allows it to protect other devices in its circuit from over-current. The Zener Diodes SMA (DO-214AC) RoHS package meets the RoHS requirements for material-free packaging, which is why this part is one of the most widely used parts for high temperature applications. It is also ideal for automotive, communications, consumer, industrial, and medical applications.
