Microsemi is a long-time supplier of high-reliability discrete components to military, aerospace, and medical customers. Microsemi has transformed itself into a global supplier of high performance analog, mixed-signal integrated circuits and high reliability discrete semiconductors that manage and regulate voltage, current and power, as well as protect against transient voltage spikes, and transmit, receive and amplify electronic signals.

Our products include linear microcircuits, digital microcircuits, op amps, logic array networks, analog control circuits, and a variety of discrete devices (transistors, quad transistors, FETs, diode arrays, glass rectifiers, and many other diode products including Zeners, Transient Voltage Suppressors, Current Limiters, Reference Diodes, and Signal Diodes.

Microsemi specializes in assembly of hermetic packages, such as: Flat Packs, DIPS, TO-46, TO-18, TO-87, TO-39, TO-99, TO-3, TO-254, TO-257, TO-258, as well as DO-4, DO-5, DO-7, DO-8, DO-9, DO-13, DO-35, DO-213AA, DO-213AB and many other thermally matched void- less metallurgically-bonded hirel packages in both axial-leaded and MELF designs (for through-hole and surface mount applications respectively) to name a few.
