FET, MOSFET Arrays Procurement Notes

Verify authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors to avoid counterfeit components. Confirm the specific suffix designation matches the required packaging format, as the tape and reel variant contains four thousand pieces per reel. Ensure all procurement documentation aligns with the manufacturer's general terms and conditions regarding liability and product usage restrictions.

FET, MOSFET Arrays Selection Notes

Select this component when a compact solution requires matched N and P-channel performance within a limited footprint. Evaluate thermal resistance constraints carefully, as the specified junction-to-ambient value assumes minimum recommended pad sizes on FR4 substrates. Verify that the required gate drive voltages fall within the specified ranges to ensure optimal on-resistance and switching speed characteristics for the target application load.

FET, MOSFET Arrays Part Context

This part belongs to the MCQ4559 series manufactured by Micro Commercial Components. It utilizes a silicon-based MOSFET technology housed in an SOP-8 surface mount package. The device is designed for general-purpose switching applications where space efficiency and complementary channel integration are prioritized over high-power handling capabilities found in larger packages.

FET, MOSFET Arrays Replacement Considerations

Direct substitutes must match the 60V rating, SOP-8 package, and dual N/P-channel configuration. Verify pinout compatibility and thermal resistance specifications before implementation. Cross-referencing with other manufacturers' dual MOSFET arrays requires careful validation of electrical parameters such as on-resistance and gate charge to ensure circuit performance remains unaffected.

FET, MOSFET Arrays FAQ

What is the maximum pulsed drain current for the N-channel?

The maximum pulsed drain current for the N-channel is 18 Amperes, tested under pulse width conditions of 300 microseconds or less with a duty cycle of 2 percent or less.

Does the device support automotive grade reliability?

The provided datasheet does not specify AEC-Q100 qualification or automotive grade certification for the MCQ4559-TP. It is rated for industrial operating temperatures but lacks explicit automotive compliance documentation in the source material.

How is the gate threshold voltage defined?

The gate threshold voltage is defined as the voltage required to achieve a drain current of 250 microamperes with the drain-source voltage equal to the gate-source voltage. For the N-channel, it ranges from 1V to 3V, and for the P-channel, it ranges from -1V to -3V.
