Microchip Introduces 3 kW Transient Voltage Suppressor Diode Array Family for Superior Circuit Protection in Harsh Environments

To ensure important functions, aviation and house units rely on digital and logic performance and circuitry in engine handle units, environmental controls, instruments and actuators. Info centers, the 5G infrastructure and interaction units also rely on advanced circuitry requiring security. Just about every technique need to run continuously despite voltage surges and spikes from lightning, solar functions and electromagnetic incidents. Microchip Technological know-how Inc. (Nasdaq: MCHP) right now declared its recently-expanded portfolio of Transient Voltage Suppressor (TVS) vertical arrays – the MDA3KP Transient Voltage Suppressor (TVS), a three kW diode relatives of extra than 25 goods with diverse screening levels, polarities and qualification specifications.

Microchip’s MDA3KP TVS diode array relatives – the only offered technological know-how presenting a detailed voltage variety analyzed to a superior dependability common and certified based mostly on the MIL-PRF-19500 JANTX degree equivalence common – provides an integrated multi-diode alternative. These voltage-clamping equipment offer rapidly-reacting Avalanche Breakdown Diode (ABD) functions that divert excess recent around delicate factors to protect them from electrical overstress.

“Digital controls, logic and diagnostic technique circuit blocks require highly reputable, secure recent and power security to ensure functions in intense environments,” mentioned Leon Gross, vice president of Microchip’s Discrete Item Group company unit. “This diode relatives also addresses the challenges technique designers confront with a extra productive vertical building and requirement for a lot less board house than other equipment.”

MDA3KP TVS diode arrays are offered in the adhering to screened version market specifications: M, MA, MXL and MX. The equipment have been exposed to various levels of testing to ensure they meet up with the aircraft lightning security specifications established forth in the common for environmental testing of avionics, RTCA DO-160G (Lightning Induced Transient Susceptibility). RTCA is the market consortium that develops consensus on important aviation modernization concerns.

The MDA3KP TVS diode array, a vertically constructed 8-diode, sixteen-pin area mount deal, allows for productive structure and ease of style and design, as a lot less printed circuit board house is demanded whilst enabling higher power densities. In the MDA3KP TVS diode array relatives, each device’s vertical building provides the power of eight lesser equipment on a printed circuit board, removing the want for the numerous equipment even as it provides higher power.

Readily available in unidirectional and bidirectional building in standoff voltages of 6V to 40V, the factors offer Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT) security according IEC specifications and a Peak Pulse Ability rating of 3000 W at 10/a thousand µs. With an extended temperature variety from -55°C to +150°C, the equipment are good deal traceable, surge analyzed, and Humidity Sensitivity Level (MSL) Level 1 – demonstrating that these equipment are completely ready for use in severe environments. MSL signifies that no dry pack or bake is demanded prior to use. The MDA3KP TVS diode array family’s power rating is the industry’s only offered technological know-how with this degree of screening in this deal.

Microchip’s three kW MDA diode relatives provides army technique circuit security for ruggedized handheld radios, the World Positioning System (GPS) and interaction test gear. Other product purposes include automotive, industrial logging gear, power materials and maritime units.
