Toshiba introduces two bidirectional transient voltage suppression diodes

     Toshiba "introduces two bidirectional transient voltage suppression diodes (electrostatic discharge protection diodes)" DF2B5PCT "and" DF2B7PCT "for increasing the rated peak pulse current of the standard capacitor types applicable to IC power lines. Available in small SOD-882 package (Toshiba package name: CST2). Due to the reduced surface area of the board, it can be used in various applications, including mobile devices.

     The two new products have a rated peak pulse current  of 27A and a typical dynamic impedance  of 0.1Ω. Compared with the bidirectional transient voltage suppression diode DF2B7BSL, which has a high rated peak pulse current , the electrostatic discharge absorption performance of the new product increases the peak pulse current  by about three times, reduces the typical dynamic impedance  by about 50%, and achieves a low clamping voltage . Thus increased stability.

     The new products include DF2B7PCT for standard 5V power lines and DF2B5PCT for 3.3V power lines. Select the appropriate transient voltage suppression diode based on the voltage, thereby protecting ics and other devices from damage in subsequent stages by suppressing excessive power supply transient voltages.

     The miniaturization process of ics has continuously reduced the electrostatic discharge capacity, so the stability requirements of mobile devices such as smartphones and tablets are also constantly increasing. In addition, in order to prevent the transient overvoltage damage caused by electrostatic discharge, lightning induction and poor power supply, it is necessary to provide transient overvoltage protection for the device, so the protection device itself also needs a high peak pulse current. To meet these requirements, we have developed a new set of products featuring high rated peak pulse currents and low dynamic impedances.
