CMSH9930Q8-HF

Overview

The CMSH9930Q8-HF is a MOSFET array manufactured by Comchip Technology, housed in an 8-SOP surface-mount package. It integrates two complementary channels: one N-channel and one P-channel. The device supports a drain-source voltage of 30V for both configurations. The N-channel exhibits a continuous drain current of 6A, while the P-channel provides 4.4A. On-resistance values are specified at 21 milliohms for the N-channel and 25 milliohms for the P-channel when driven at a gate-source voltage of 10V. The total power dissipation capacity is rated at 1.38W.

Feature Summary

• Integrates dual complementary N-channel and P-channel MOSFETs within a single compact surface-mount package.
• Features low on-resistance characteristics to minimize conduction losses and enhance overall circuit efficiency.
• Designed for high-speed switching applications with optimized thermal performance for dense layouts.

Applications

• DC-DC converter synchronous rectification stages
• Motor driver bridge circuits
• Low-voltage load switch implementations

Procurement Notes

Verify the specific suffix designation against the manufacturer's latest documentation to ensure compatibility with required pinout and electrical tolerances. Confirm that the 8-SOP package dimensions align with the target PCB footprint constraints. Cross-reference the maximum power dissipation rating with the intended thermal management strategy to prevent overheating during continuous operation.

Selection Notes

Select this component when space-constrained designs require integrated complementary switching pairs. The 30V voltage rating suits low-voltage logic-level systems. Evaluate the 1.38W power dissipation limit against the expected thermal environment. Ensure the gate drive voltage meets the threshold requirements for achieving the specified low on-resistance values effectively.
