BZX84-C2V7.215 – PHILIPS

Overview

The Nexperia BZX84-C2V7,215 is a highly precise 2.7V Zener diode designed for robust voltage regulation in compact surface-mount applications. Its critical operational characteristic is its tight ±5% tolerance, ensuring stable reference voltages essential for sensitive analog circuitry. A key design consideration often overlooked is the trade-off between its 250mW power dissipation and its impedance (Zzt) of 100 Ohms; achieving lower impedance typically requires larger die sizes or more complex internal structures, which are incompatible with the SOT-23 package. This component excels where space and precise voltage clamping are paramount.
