Microchip Technology MDA3KP SMD 3000W Vertical TVSs

Microchip Technology MDA3KP SMD 3000W Vertical Transient Voltage Suppressors (TVS) are 3kV diode arrays designed to protect aircraft, space systems, critical infrastructure, and communications systems from surges, spikes, and electrostatic events. The high-reliability TVS diode arrays from Microchip Technology are available with unidirectional and bidirectional construction in standoff voltages of 6V to 40V, provide electrostatic discharge (ESD), electrical fast transients (EFT) protection according to IEC standards, and a peak pulse power rating of 3000W at 10/1000µs. The devices offer an extended temperature range from -55°C to +150°C.

These voltage-clamping devices provide fast-reacting avalanche breakdown diode (ABD) features that divert excess current around sensitive components to protect them from electrical overstress and address the challenges of board space with vertical construction. The vertically constructed 8-diode, 16-pin, SMD package allows for an efficient layout and ease of design, reducing printed-circuit-board (PCB) space while enabling higher power densities. Each device’s vertical construction provides the power of eight smaller devices on a PCB, eliminating the need for multiple devices even at higher power. The devices are lot traceable, surge tested, and moisture sensitivity level (MSL) Level 1 rated, indicating that these devices can be used in harsh environments. No dry pack or bake is required prior to use.

MDA3KP TVS diode arrays are available in the following screened version industry standards: M, MA, MXL, and MX. The devices have undergone various levels of testing to ensure they meet the aircraft lightning protection requirements in the standard for environmental testing of avionics, RTCA DO-160G (Lightning Induced Transient Susceptibility). The 3-kW MDA diode family provides military system circuit protection for ruggedized handheld radios, global positioning systems (GPS), and communication test equipment. Other device applications include automotive, industrial logging equipment, power supplies, and marine systems.
