Optimize Military Drone Performance with DEI ASICs
Proven aerospace-grade ASICs for flight systems, monitoring, and diagnostics.
DEI1606-MES-G
The DEI1606 Surge Blocking Module (SBM) is a high voltage, bidirectional current limiting element implemented with proprietary Silicon Carbide FET technology. The device is intended to be used in conjunction with a Transient Voltage Suppressor (TVS) diode to implement a current limiting / voltage clamping protection network. While similar to the DEI1604, the DEI1606 is fuseless, featuring a smaller 8L DFN package for additional space savings benefit.

Functional Description In normal operation, the SBM acts as a low value series resistor (< 1.7Ω including both FETs) and is designed to operate at currents up to ±0.45A. In surge stress operation, the TVS device conducts surge current when the surge voltage exceeds the TVS standoff voltage. The series SBM limits the surge current to a few Amps, thus allowing use of small, low power, low capacitance TVS diodes to provide the voltage clamp protection.
