TVS Diodes in DFN3820A Package

Vishay's four series of surface-mount, industrial-grade TRANSZORB, and automotive-grade PAR transient voltage suppressors (TVS) are available in a low-profile DFN3820A package with wettable flanks. Providing space-saving solutions for automotive, computer, consumer, and industrial applications, the 6DFNxxA, 6DFNxxxCA, T6NxxA, and T6NxxxCA offer a peak pulse power of 600 W at 10/1,000 μs and low leakage current down to 1 μA. The first package in Vishay’s power DFN family, the DFN3820A’s compact footprint and low profile allow the devices to make more efficient use of the PCB space. Footprint-compatible with the SMP (DO-220AA) package, the DFN3820A is 85% smaller than the SMB (DO-214AA) and 42% smaller than the SlimSMAW (DO-221AD) but keeps peak pulse power dissipation with a 10/1000 μs waveform at 600 W. The 6DFNxxA, 6DFNxxxCA, T6NxxA, and T6NxxxCA are designed to protect sensitive electronic equipment against voltage transients induced by inductive load switching and lightning.
