Two series of TVS Diodes designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events has been introduced by Littelfuse. The AEC-Q101 qualified TP1.5KE and TP5KP series Automotive Transient Voltage Suppression (TVS) Diodes offer a choice of 1500W (TP1.5KE) or 5000W (TP5KP) peak pulse power dissipation ratings in standard DO-201 and P600 axial-lead packages respectively.
Their high peak pulse power dissipation ratings help the power systems into which they are designed pass surge tests outlined in the ISO7637-2 International Standard, which is widely used in the automotive industry as the basis for transient specifications.
Applications for the TP1.5KE and TP5KP Series include DC line protection and ESD protection in automotive electronics such as electronic control units, sensors, entertainment systems, and Body Control Modules (BCMs); they are also useful for the protection of I/O interfaces, VCC busses and other vulnerable circuits used in telecom, computer, industrial and portable consumer electronics applications.
“For automotive electronics systems applications, these TVS Diodes outperform conventional circuit protection technologies like Metal-Oxide Varistors (MOVs) and Multi-Layer Varistors (MLVs), due to their AEC-101 qualified designs, low reverse voltage breakdown and low voltage clamping ratings,” said Charlie Cai, Global Product Marketing Manager for Littelfuse. “They also have no wear-out mechanism, ensuring longer life.” TP1.5KE and TP5KP series TVS Diodes from Littelfuse offer these key benefits:
