The YAZ1P5D3V3 to YAZ1P5D240 series utilizes SMA-packaged silicon planar Zener diodes, offering an industrial-grade voltage regulation range of 3.3V to 240V and a maximum power dissipation of 1.5W. They feature a wide voltage dropout range of 216V to 264V, a minimum test current of 1600μA, and 1.5W of continuous power output.
This series offers ±5% or ±10% voltage accuracy options, test currents ranging from 1mA to 113.6mA, and dynamic impedance as low as 1.5Ω. Reverse leakage current is as low as 1μA at the rated voltage at 25°C, while the maximum DC Zener current reaches 454mA.
These devices are solder-certified to MIL-STD-750 and operate in harsh environments ranging from -55°C to +150°C. The SMA package measures 4.5×2.7mm, with a maximum height of 2.2mm and weighs only 0.055g, optimizing space utilization for high-power density designs.
Designed for overvoltage protection of power modules and industrial equipment, these products feature electrical characteristics based on 20ms pulse testing. Dynamic impedance is linearly optimized with increasing voltage, and the 240V high-voltage model maintains a 1.5Ω impedance characteristic, supporting the precise voltage regulation requirements of motor drive systems, photovoltaic inverters, and communication base station power supplies.
