Overview
The CMS15P03Q8A-HF is a P-channel silicon MOSFET manufactured by Comchip Technology, designed for power management applications. It features a drain-to-source voltage (Vdss) rating of -30V and a continuous drain current (Id) of 15A at case temperature. The device exhibits a maximum on-resistance (Rds(on)) of 0.012Ω. It is housed in an SOP-8 surface-mount package with thermal dissipation ratings of 1.5W at ambient temperature and 4.5W at case temperature.
Feature Summary
- High-efficiency switching capability in a compact surface-mount form factor
- Robust power switch design for reliable performance
- Optimized for high-frequency operation in power management circuits
Applications
- Power management systems
- High-frequency switching applications
- Compact electronic circuit designs requiring surface-mount components
Procurement Notes
This component is currently listed as no longer manufactured by the producer. Potential buyers should verify availability through authorized distributors or secondary markets. Tariff regulations may apply if shipping to the United States; costs are calculated separately during checkout. Due to its end-of-life status, sourcing original units may require careful verification of authenticity and storage conditions.
Selection Notes
Engineers selecting this part must account for its discontinuation status. Designers should evaluate the -30V Vdss and 15A Id specifications against their load requirements. The SOP-8 package limits thermal handling compared to larger packages; therefore, PCB layout and heat sinking strategies must align with the 1.5W (Ta) and 4.5W (Tc) dissipation ratings. Alternative solutions should be considered for new designs due to supply chain constraints.
Part Context
Comchip Technology produces discrete semiconductors including MOSFETs and diodes. The CMS15P03Q8A-HF belongs to their single FET lineup, targeting efficiency and reliability in modern electronics. This specific model represents a P-channel variant optimized for low on-resistance and fast switching speeds within a small footprint suitable for dense board layouts.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Given the discontinued status, engineers should consult manufacturer cross-reference guides or distributor databases for compatible P-channel MOSFETs with matching -30V, 15A, and SOP-8 specifications.
