BZX84-C13 – PHILIPS

Overview

The PHILIPS BZX84-C13 is a high-stability Zener diode designed for precise voltage regulation in sensitive electronic circuits. Its nominal working voltage of 13V, coupled with a tight 5% tolerance, ensures predictable performance critical for analog signal conditioning and bias stabilization. A key design consideration when utilizing this device is managing its total power dissipation (Ptot ≤ 250 mW); exceeding this limit, especially during transient events with its non-repetitive peak reverse power dissipation (PZSM ≤ 40 W), can lead to thermal runaway and premature component failure, necessitating careful thermal design and current limiting.
