Transient voltage suppression devices reach 11 kW with flat clamping
Vishay’s XFD11KxxCA flat-clamping transient voltage suppression (TVS) devices provide 11 kW of peak pulse power dissipation at 10/1000 µs. Offered in surface-mount DO-218AC packages, the bidirectional devices maintain a low clamping ratio (VC/VBR) close to 1.0, supporting high power density.
The XFD11KxxCA series comprises 15 devices, each available in commercial and AEC-Q101 qualified grades. They have clamping voltages of 40.6 V to 104.0 V, breakdown voltages from 36.7 V to 104 V, and standoff voltages from 33 V to 85 V, making them suitable for 12-V, 24-V, and 48-V automotive powertrains. At the same standoff voltage, they have lower clamping voltage than conventional TVS products in DO-218 packages and deliver approximately 1.6 times higher peak pulse current, up to 207.1 A at 10/1000 µs.
Additional key specifications include an 8/20-µs surge capability of up to 2140 A and maximum leakage current of 10 µA at the standoff voltage (VWM) to minimize power loss. The series’ low, stable clamping and breakdown voltages over a wide temperature range of -55°C to +175°C allow the use of lower-voltage downstream components, reducing voltage overshoot and enabling smaller design guard bands.
Samples and production quantities of the XFD11KxxCA series are available now, with lead times of 12 weeks.
