Littelfuse 5KP33A Transient Voltage Suppression Diode

The Littelfuse 5KP series are axial-leaded transient voltage suppression (TVS) diodes specifically engineered to safeguard sensitive electronic equipment from voltage transients caused by lightning strikes and other transient voltage events. These diodes offer a 5000W peak pulse power dissipation, ensuring robust protection. They are characterized by their low incremental surge capability, fast response time, and excellent clamping voltage capability. Typical failure mode is short, and they are suitable for applications in telecom, computer, industrial, and consumer electronics, protecting I/O interfaces and VCC bus lines.
