Microchip Technology Inc. has introduced its expanded portfolio of Transient Voltage Suppressor (TVS) vertical arrays- the MDA3KP Transient Voltage suppressor (TVS). The  MDA3KP TVS family consists of more than 25 3kW diodes with different screening levels, polarities, and qualification standards and it is the only available technology that offers a comprehensive voltage range tested to a high-reliability standard and qualified based in the MIL-PRF-19500 JANTX level equivalence standard – provides an integrated multi-diode solution.

 

The MDA3KP TVS diodes are available in different screened version industry standards like M, MA, MXL, and MX and they are taken under various levels of testing to make sure that they meet the aircraft lightning protection requirements set forth in the standard for environmental testing of avionics, RTCA DO-160G (Lightning Induced Transient Susceptibility). RTCA is the industry consortium that develops consensus on critical aviation modernization issues.

 

The MDA3KP TVS diode array, a vertically constructed 8-diode,16-pin surface mount package provides an efficient layout and ease of design and each device in the family is vertically constructed to provide the power of eight smaller devices on a PCB and to eliminate the need for multiple devices even as it provides higher power.

 

The new voltage clamping devices are designed with a fast-reacting Avalanche Breakdown Diode (ABD) feature for diverting excess current around sensitive components to protect them from overstress. The devices are traceable, surge tested, and Moisture Sensitivity Level (MSL) Level 1, hence they are suitable to be used in harsh environments. MSL indicates that no dry pack or bake is required prior to use.

 

Microchip’s 3 kW MDA diode family provides military system circuit protection for ruggedized handheld radios, the Global Positioning System (GPS) and communication test equipment, they can also be used in device applications such as automotive, industrial logging equipment, power supplies, and marine systems.
