Littelfuse 5KP40A Transient Voltage Suppression Diode

The Littelfuse 5KP series is a range of axial-leaded transient voltage suppression diodes specifically engineered to safeguard sensitive electronic equipment from voltage transients induced by lightning 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. The 5KP40A, in particular, is suitable for applications in telecom, computer, industrial, and consumer electronics where protection of I/O interfaces, VCC bus, and other vulnerable circuits is critical.
