BZX85C10V – MAGNATEC

Overview

The MAGNATEC BZX85C10V is a robust 10V Zener diode designed for precise voltage regulation in demanding electronic circuits. Its primary function is to maintain a stable output voltage, crucial for protecting sensitive downstream components from overvoltage conditions. A key design consideration when implementing this DO-41 package is managing thermal dissipation; while rated at 1W, exceeding this limit, especially in compact, high-density PCBs, can lead to premature failure or performance degradation, necessitating careful heatsinking or derating in high-ambient temperature environments.

Key Features

• Nominal Zener Voltage: 10V
• Maximum Power Dissipation: 1W
• Zener Voltage Tolerance: ±5%
• Maximum Zener Impedance: 7Ω @ 25mA
• Maximum Reverse Leakage Current: 500nA @ 7V
• Package Type: DO-41 (Through Hole)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

• Precision voltage reference generation in analog signal processing chains.
• Overvoltage protection for sensitive microcontrollers and FPGAs.
• Stabilizing bias voltages for discrete transistor amplifiers.
• Shunt regulation in low-power DC-DC converter feedback loops.
