TPSMC and TPSMD Series Automotive TVS Diodes
What Are They? What Do They Do?
The TPSMC and TPSMD Series Automotive TVS Diodes are designed specifically to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events.
They provide 1500W (TPSMC) or 3000W (TPSMD) peak pulse power dissipation in a standard DO-214AB SMC/SMD package, one of the most popular form factors in automotive applications.
Both TPSMC and TPSMD Series TVS Diodes are AEC-Q101 qualified.

TPSMC and TPSMD Series Automotive TVS Diodes
What Do They Offer?
Features Benefits
• Peak pulse power (Pppm) dissipation
rating of 1500W for TPSMC and 3000W
for TPSMD
• Very popular power dissipation rating for
automotive applications. Helps the power
system pass the different 1, 2a, 2b, 3a,
3b and 5b surge tests operationally as
specified by ISO7637-2
• AEC-Q101 qualified • Automotive-grade products are well-
suited for high reliability applications
• SMC/SMD package (DO-214AB) • Standard package and compact footprint
allow quick and easy layout in high
reliability applications
• Both uni-directional and bi-directional
polarity devices offer 10V to 77V standoff
voltage range for TPSMC Series; TPSMD
Series offers 10V to 43V standoff voltage
range for unidirectional.
• Wide standoff voltage range fulfills all
design requirements for automotive
applications
• Comply with IEC 61000-4-2 and IEC
610000-4-4 standards
• Helps designers meet global regulatory
standards
