5KP33CA-TP Circuit Protection

A Transient Voltage Suppressor Diode, or TVS for short, is a form of surge protection device. Designed to protect against voltage transients, such as those caused by electrical overstresses, electrostatic discharge (ESD) and induced electrical fields, TVS diodes offer protection devices for all types of circuits and applications.

5KP33CA-TP is a TVS diode manufactured by Littelfuse, Inc., a global leader in circuit protection. The 5KP33CA-TP is designed to protect electronic components from the damaging effects of voltage transients. It features an industry standard 5.0mm package that is compatible with a variety of industry standard footprints, a low breakover voltage of 33V (33A) which helps with space and cost savings, and a low initial clamping voltage of 42V. The 5KP33CA-TP is also compatible with reflow technology and has a lead-free solder finish.

The 5KP33CA-TP provides excellent protection from ESD transient strikes of greater than 25kV (contact) and 45kV (air) and is able to handle repetitive surges of up to 150A. It is suitable for a wide variety of applications, including cell phones, digital cameras/camcorders, medical equipment, and other consumer electronics. This diode also offers excellent transient protection up to 1MHz, making it ideal for use in a variety of industrial applications. It is also designed to meet AEC-Q101 specifications and is UL recognized to UL 783 and CSA certified to CSA C22.2 No. 235

The working principle of the 5KP33CA-TP Transient Voltage Suppressor Diode is based on the avalanche effect. When an extra pulse voltage is applied to the diode, it starts to conduct electric current faster than the normal avalanche effect. This increases the internal temperature of the diode and causes the electrons to rapidly increase in speed, which results in an increased conduction current through the diode. This current is then able to expand the area of protection and protect connected components from surge and transient voltage spikes.

In conclusion, the 5KP33CA-TP Transient Voltage Suppressor Diode from Littelfuse, Inc. is a popular choice for applications requiring increased protection from voltage transients. With its unique design, low voltage rating, and ESD protection of up to 25kV (contact) and 45kV (air), this diode offers excellent protection for a variety of applications including cell phones, digital cameras/camcorders, medical equipment, and other consumer electronics. It is also designed to meet AEC-Q101 specifications and has a lead-free solder finish.
