BZT52B5V6 is an SMD planar Zener diode designed for voltage stabilization and regulation applications. It features a nominal Zener voltage of 5.6V with a typical tolerance of ±2%, sharp Zener voltage breakdown characteristics, and low leakage current. The device is rated for 500 mW power dissipation at 75°C ambient temperature, with a maximum junction temperature of 150°C and thermal resistance of 340 K/W (junction to ambient). Housed in the compact SOD-123F surface-mount package with dimensions of 3.8 × 2.7 mm, it is ideal for commercial and industrial-grade voltage regulation circuits, overvoltage protection schemes, and precision power supply designs where reliable voltage reference performance is required.
