15V 1Watt Zener Diode SMD 1SMA4744A

The 1SMA4744A is a 15V, 1W surface-mount silicon planar Zener diode manufactured by Microdiode Semiconductor (MDD) for voltage regulation, voltage clamping, and overvoltage protection applications. Housed in a compact surface-mount DO-214AC (SMA) molded plastic package, this discrete component features a single diode configuration designed with a low profile to optimize automated board placement. It operates with a nominal Zener breakdown voltage of 15V and a maximum power dissipation of 1W while carrying the package top-side marking code "744A". Engineered with a maximum forward voltage drop of 1.2V at a 200mA test current and low reverse leakage, this robust device delivers reliable performance across an operating junction temperature range from minus 55 to plus 150 degrees Celsius.
