According to foreign media reports, Vishay Intertechnology has launched four new series of surface mount industrial grade TRANSZORB ®and gauge grade PAR ®transient voltage suppressors (TVS), all in a thin DFN3820A package with wettable flanks (wettable flank).
6DFNxxA, 6DFNxxxCA, T6NxxA and T6NxxxCA provide space-saving solutions for automotive, computer, consumer and industrial applications, providing peak pulse power of 600W at 10 / 1000 μ s and leakage current as low as 1 μ A.
As the first package in the new Power DFN series, the DFN3820A features a compact 3.
8mm x 2.
0mm area and a very low 0.
88 mm typical height, enabling Visch General Semiconductor TVS (Vishay General Semiconductor TVS) to make more efficient use of printed circuit board (PCB) space.
The DFN3820A is compatible with the SMP (DO-220AA) package, which is 85% smaller than SMB (DO-214AA) and 42% smaller than SlimSMAW (DO-221AD), but can maintain the peak pulse power consumption of 10 / 1000 μ s waveform at 600W.
The purpose of this release is to protect sensitive electronic devices from inductive load switching and voltage transients caused by lightning.
In addition to industrial robot dashboards, process / flow control instruments and automation systems, 6DFNxxA and 6DFNxxxCA TRANSZORB TVS will also be used for signal line protection in server power modules for computer and consumer applications, digital media controllers and AV signal extenders.
T6NxxA and T6NxxxCA PAR TVS are AEC-Q101 certified and can operate at temperatures exceeding 185C for protection against sudden load drops.
Typical applications include Advanced driving Assistance (ADAS), Battery Management system (BMS), Electric Power steering (EPS) and infotainment systems, as well as central control units, vehicle chargers (OBC), DC/DC converters and traction inverters, and motor drivers.
These TVS have excellent clamping ability, in which the maximum clamping voltage of 6DFNxxA and T6NxxA is 16.7V-70.1V, and that of 6DFNxxxCA and T6NxxxCA is 16.
7V-137V.
The wettable flank in the DFN3820A package supports automatic optical inspection (AOI) without the need for X-ray inspection.
These rectifiers are ideal for automatic placement, with a MSL moisture sensitivity rating of JmurSTD-020 and a maximum LF peak of 260 °C.
These devices are RoHS-compliant and halogen-free, and their matte tinned leads conform to JESD Class 201 whisker test.
Device specification sheet: the new TVS in DFN3820A package is now available for mass production with a delivery time of 12 weeks.
