Introduction
TISP8201HDMR-S is a Mixed Technology TVS (Transient Voltage Suppressor) device. It is designed for bidirectional protection against electrostatic discharge (ESD) and low current surge transients. The TISP8201HDMR-S is a low-capacitance, low-voltage surface mount device that combines two unidirectional TVS technologies – high voltage/low capacitance (HV/LC) and ultra-fast activating avalanche breakdown (UFA) – to offer high levels of performance in suppressing these transient events. This combination of technologies allows the TISP8201HDMR-S to offer ultra-low leakage current, an enhanced maximum clamping voltage (Vc) and superior transient energy absorption.
Application Field
The TISP8201HDMR-S can be used in a wide range of applications. It is well suited for use in a variety of medical devices, such as dialysis and imaging systems. It is also suitable for use in a variety of automotive applications, such as airbag safety systems, HVAC systems, electric power steering, and high-sensitivity electronic systems. Additionally, the TISP8201HDMR-S is well suited for use in industrial and consumer products that require the highest level of protection against transient surges.
Working Principle
The TISP8201HDMR-S is composed of two separate and independent TVS elements, each of which operates in its own monitor/trigger circuit. The first element uses a high-voltage/low-capacitance (HV/LC) TVS diode with a very fast activating avalanche breakdown (UFA) to suppress the ESD transients. This element has an ultra-low leakage current and a high maximum clamping voltage (Vc). The second element uses a low-voltage/low-capacitance (LV/LC) TVS diode with a fast responding unidirectional trigger circuit that is used to suppress low-current surge transients. When a surge transient occurs the UFA element will activate, clamping the voltage and dissipating the energy as heat. When both elements are activated, the transient voltage is quickly clamped down and dissipated, providing superior transient energy absorption.
Conclusion
The TISP8201HDMR-S is an example of a Mixed Technology TVS device. It uses two separate and independent TVS elements, each with their own monitor/trigger circuit, to provide superior protection against ESD and low-current surge transients. This combination of technologies allows for an ultra-low leakage current, enhanced maximum clamping voltage (Vc) and superior transient energy absorption. The TISP8201HDMR-S can be used in a wide range of applications including medical devices, automotive systems, industrial equipment, and consumer electronics.
