Overview
The onsemi CPH3323-TL-E is a P-channel silicon MOSFET designed for ultrahigh-speed switching applications. It features a compact SOT-457 (CPH) surface-mount package with dimensions of 2.9 x 1.6 x 0.9 mm. The device supports a maximum continuous drain current of 3 A and offers a breakdown voltage of 50 V between the drain and source. With a maximum power dissipation rating of 900 mW, it is suitable for efficient power management in space-constrained designs.
Feature Summary
- Ultrahigh-speed switching capability for efficient power management
- Compact SOT-457 surface-mount package for space-constrained designs
- P-channel silicon construction for complementary circuit configurations
Applications
- Motor drivers
- Power supply circuits
- High-speed switching applications
Procurement Notes
Verify the specific datasheet version when sourcing, as manufacturer documentation may be hosted by distributors. Confirm that the ordering suffix corresponds to the intended tape-and-reel packaging configuration. Ensure compatibility with standard SOT-457 footprints during PCB layout. Cross-reference part numbers carefully to distinguish between similar NPN and P-channel variants within the same package family.
Selection Notes
Select this component for applications requiring fast switching speeds in a minimal footprint. The 50 V rating provides adequate headroom for low-voltage systems. Consider the 900 mW thermal limit when designing heat dissipation strategies. Verify gate drive requirements against the specific threshold voltages listed in the official electrical characteristics table.
Part Context
This component belongs to onsemi's lineup of small-signal discrete semiconductors. It utilizes the CPH package, also known as SOT-457, which houses three pins in a dual-side leadless form factor. This packaging allows for high-density mounting on printed circuit boards while maintaining reliable electrical connections for high-frequency operations.
Replacement Considerations
Check for direct substitutes such as the CPH3212-TL-E, noting that it is an NPN transistor rather than a P-channel MOSFET. Ensure any replacement matches the required channel type and voltage ratings. Verify pinout compatibility before substituting components in existing designs.
