TVS diodes clamp automotive transients

Two TVS diode series from Littelfuse, the TP5.0SMD-FL and TP1KSMB-FL, protect 48-V automotive electronics from voltage transients. Based on the FlatSuppressX TVS architecture, the devices exhibit a flatter clamping characteristic with a significantly lower clamping voltage than conventional TVS components. Their foldback/snapback function tightly controls transient response while avoiding latch-up risk.

The TP5.0SMD-FL series has a peak pulse power rating of up to 5 kW in a DO-214AB (SMC) package. The TP1KSMB-FL series has a peak pulse power rating of up to 1 kW in a DO-214AA (SMB) package. Devices in both series are AEC-Q101 qualified, providing scalable protection options for varying system requirements. Their architecture enhances system efficiency, enabling the use of lower-rated downstream components.

Optimized for protecting I/O interfaces, power buses, and other vulnerable circuits in automotive electronics, particularly 48-V architectures, these TVS diodes provide a fast transient response, typically in less than 1 ps.

The TP5.0SMD-FL and TP1KSMB-FL series are available in tape and reel format in quantities of 3,000. Sample requests are accepted through authorized Littelfuse distributors worldwide.
