TISP4220M3BJR-S

The TISP4220M3BJR-S is a high-speed, low-capacitance, low-current television thyristor. It is designed to protect low-current housings, such as mobile phones and laptops, from over-voltage or electrostatic discharge (ESD), and works with an integrated surge absorber. As a member of the TVS (Thyristors) family, the TISP4220M3BJR-S provides high-efficiency surge protection performance and improved discharge capability.

The TISP4220M3BJR-S is suitable for electronic devices that require ESD protection and must be compliant with IEC61000-4-2 and JEDEC standards. It protects the device from damage caused by transient voltage such as lightning, power surges, and static discharge. The device does not degrade with age, features a small footprint, and withstands a wide operating temperature range.

The TISP4220M3BJR-S thyristor works on the principle of utilizing a semiconductor junction that behaves as a rectifier under alternating current. When the current applied to one external connection is less than a predetermined threshold, the junction is forward-biased, allowing electrons to flow freely, creating a conduction path. When the current applied to the second external connection exceeds this threshold, the junction is reverse-biased, blocking further current flow and deactivating the conduction path. This principle is illustrated in the figure below.

The TISP4220M3BJR-S features built-in ESD protection, which is an important feature for protecting sensitive electronic components against external electrostatic shocks. It is designed to protect against voltage transients up to 400V, withstand up to 1.5A peak transient current, and operate up to a maximum voltage of 55V. The device features excellent switchability and fast surge response times for superior ESD protection.

In summary, the TISP4220M3BJR-S is an excellent choice for providing high-efficiency surge protection and a reliable form of ESD protection in sensitive electronic components, such as mobile phones and laptops. It is tailored to meet the stringent requirements of IEC61000-4-2 and JEDEC standards and can withstand up to 400V of transient voltage. The device is small, power efficient, and performs well even at wide operating temperatures.
