TVS - Diodes

TVS diodes are an electrostatic discharge device mostly used as over-voltage protection for sensitive electronic components against high voltages. This type of diode is specifically designed for fast response times to transient pulses of high voltage and current. It presents a high level of protection in a small package and is very well suited for use in portable and low-cost applications like medical and communications devices. The CPDQC5V0USP-HF is a 5 V rating, 0.1 A bidirectional TVS diode.

CPDQC5V0USP-HF Application Field and Working Principle

CPDQC5V0USP-HF protects your sensitive electronic components from the destructive disturbances such as lightning, AC power induction and electrostatic discharge. It is especially suited for use in low voltage applications in portable and telecom devices. This diode is compatible with industrial and automotive temperatures and is also AEC-Q101 qualified.

This TVS diode is made up of a metal-oxide varistor (MOV) and a series diode chain mounted on a lead frame which is then encapsulated in the epoxy resin with the pins of the diode. The diode is a uni-directional device whose working principle is triggered by over-voltage. The glass passivated junction of the CPDQC5V0USP-HF provides superior surge protection due to an extra fast response time. The lead frame ensures a uniform thermal path, making the diode last longer when exposed to continuous high currents.

The CPDQC5V0USP-HF TVS diode also has a low capacitance and a low clamping voltage, making it suitable for a wide range of applications. This diode has an easy to handle, flat package with a thickness of only 0.8mm and is therefore ideal for use in portable devices. The CPDQC5V0USP-HF TVS diode is typically used in a variety of applications in fields such as automotive, consumer, industrial, medical, and telecom.

The CPDQC5V0USP-HF is suitable for high-speed data line protection in applications like USB 2.0 boards and consumer electronics. It can also be used in high current applications like power supply protection in home appliances, automotive power systems, and power supplies. The device has excellent transient protection performance and provides maximum protection against high voltage transient impulses.

This diode is also suitable for protecting against electrostatic discharge (ESD) in consumer electronic devices, medical devices, and motor control applications. It is compliant with international standards such as IEC 61000-4-2 (8 kV contact discharge) and IEC 61000-4-4 (2 kV air discharge). It has a surge capability of 8 A, 8/20 µs and a holding current of 0.1 A.

The CPDQC5V0USP-HF is a bidirectional TVS diode with superior performance, low capacitance, and excellent transient protection performance in an easy to handle package. Its fast response time and wide range of compatible temperatures make it a suitable choice for a variety of applications in portable devices, home appliances, automotive systems, medical devices, and telecom devices.
