BZT03C7V5V – VISHAY

Overview

The Diotec Semiconductor BZT52C7V5 is a 7.5V Zener diode designed for precise voltage regulation in compact electronic assemblies. Its critical operational characteristic lies in its low Zener impedance of 30 Ohms at a test current of 5 mA, ensuring stable output voltage with minimal ripple rejection. A common design trade-off when selecting such a low-power device is managing thermal dissipation; with a maximum power dissipation of 500 mW, careful consideration of ambient temperature and duty cycle is paramount to prevent exceeding its +150°C maximum operating temperature and ensure long-term reliability, especially in densely populated PCBs.
