Vishay 3000 W transient voltage suppressors in DFN6546A package

They are designed to protect electronics against voltage transients induced by inductive load switching and lightning.

DFN6546A

The diodes are in the new DFN6546A package with wettable flanks and are aimed at industrial and automotive applications. For example, advanced driver assistance (ADAS), lidar, camera, infotainment, and sensor systems, for automotive. And robot control boards, process flow control instrumentation, automation systems, and generator start controllers, for industrial.

The Automotive Grade T3KNxxA and T3KNxxCA (pictured) series devices are AEC-Q101 qualified and offer high temperature operation to +185 °C, while the 3KDFNxxA and 3KDFNxxCA series meet the LL15i Industrial Reliability Qualification.

Clamping

Vishay writes:

“For these applications, the diodes offer excellent clamping capability with maximum clamping voltages from 16.7 V to 33.2 V for the T3KNxxA and 3KDFNxxA, and 16.7 V to 137 V for the T3KNxxCA and 3KDFNxxCA. The wettable flanks of their DFN6546A package allow for automatic optical inspection (AOI), eliminating the need for an X-ray inspection.”

“Ideal for automated placement, the devices offer a MSL moisture sensitivity level of 1, per J-STD-020, LF maximum peak of 260 °C. The components are RoHS-compliant and halogen-free, and their matte tin-plated leads meet the JESD 201 Class 2 whisker test.”

The DFN6546A features a compact 6.5 mm x 4.6 mm footprint and a low typical height of 0.88 mm, highlights Vishay, for the TVS diodes to make more efficient use of PCB space.

Samples and production quantities of the 3000 W TVS in the DFN6546A package are available now. Vishay quotes a lead time of 12 weeks.
