Littelfuse Introduces TVS Diodes

Littelfuse, a global leader in circuit protection, announced the launch of the TPSMB series of transient voltage suppression (TVS) diodes. The product is designed to provide secondary protection for sensitive automotive and other electronic components that induce transient voltages during load dumps and other transient voltage events. This product is ideal for protecting the input/output interface, VCC bus, and other fragile circuits in automotive applications because it meets the automotive electronics board's Q101 automotive-grade discrete semiconductor fatigue test standard (AEC-Q101 certification). Its compact, small-size DO-214AA SMB package simplifies board layout and is one of the most popular forms of packaging in automotive applications.

The TPSMB series TVS diodes have a rated off-state voltage range of 11V to 77V in both uni-directional and bi-directional devices and can meet a wide range of design needs in automotive applications.

Typical applications for the TPSMB series include automotive electronics and electronic control devices in portable devices that require high reliability, sensors, DC power for entertainment systems, and ESD protection.

“The TPSMB series' compact DO-214AA package and 600W power rating make it an excellent secondary for high-reliability, automotive and portable equipment applications,” said Charlie Cai, Global Product Manager for Automotive Transient Voltage Suppression and High-Reliability TVS Diodes. Protection solutions.The series also meets the AEC-Q101 standard, which is an important factor for automotive manufacturers because it means that these products are suitable for demanding automotive applications and do not require additional component quality testing. ."
