TPSMB43CA is a surface mount unidirectional triode transient voltage suppressor (TVS) diode especially designed to protect high-speed data and transmission lines from voltage transients induced by order discharge or electrostatic discharge (ESD). The device comes in an SOT-413 package and has a peak pulse power of 700 watts.

Application Field

TPSMB43CA is a prodcuct of microsemi and mainly used to protect high-speed data and transmission lines from disturbances caused by fast transient voltages. It can provide wide protection from Charge Device Model (CDM) and ESD. It is also suitable for power protection, and communication network and automotive applications. The applications fields are audio lines, low voltage power supplies, telecom/datacom lines, USB ports, automotive, home appliance and other high-speed data applications.

Working Principle

The TPSMB43CA uses a combination of a TVS diode and a unidirectional anode to provide protection against transient voltages. The TVS diode acts like a reverse biased regular diode, and so it is able to absorb the transients caused by order discharge or ESD. Its unidirectional anode functions by diverting additional energy from high-current transients to a storage element, dampening their impact and allows the product to achieve peak pulse power of 700W. In addition, the storage element absorbs power and decreases the let-through energy. The efficiency of TPSMB43CA is realized by the combination of unidirectional and bi-directional TVS diodes to suppress both positive and negative transient values.

TPSMB43CA is ideal for protecting high-speed transmission lines and data systems from transient events induced by order discharge or ESD. Its variety of features and low power consumption make it the ideal choice for protecting against CDM and ESD. If you are looking for a device with excellent protection form fast transient voltages, then the TPSMB43CA is a good option.
