Overview
The AO3415B is a P-Channel Enhancement Mode Field Effect Transistor manufactured by Alpha & Omega Semiconductor. It features a maximum drain-source voltage (Vds) of -20 V and a continuous drain current (Id) of -5.8 A at 25°C. The device utilizes a compact SOT-23 surface-mount package with three pins. Key electrical characteristics include a low on-resistance (Rds(on)) of 0.045 Ω at Vgs = -10 V, ensuring efficient power handling. The component operates within a junction temperature range of -55°C to +150°C and complies with RoHS standards for lead-free construction.
Feature Summary
- P-Channel enhancement mode architecture for low-side switching applications
- Ultra-low on-resistance optimized for high-efficiency power management
- Compact SOT-23 surface-mount footprint for space-constrained designs
Applications
- Power management circuits in portable consumer electronics
- Load switches for battery-powered devices
- DC-DC converter output stages
Procurement Notes
Verify the specific datasheet revision and manufacturer lot codes upon receipt to ensure compliance with the stated electrical parameters. Confirm that the component matches the AO3415B designation exactly, as suffixes may indicate variations in packaging or testing criteria defined by Alpha & Omega Semiconductor. Cross-reference part markings against official manufacturer documentation to authenticate origin and prevent counterfeit substitution.
Selection Notes
Select this component when a -20 V P-Channel MOSFET with approximately -6 A current capability is required in a small outline transistor package. Ensure the application voltage does not exceed the rated drain-source limit and that thermal management supports the specified power dissipation in the SOT-23 form factor. Compare input capacitance and gate charge requirements against the driving circuit capabilities for optimal switching performance.
Part Context
The AO3415B belongs to the AO34xx series of P-Channel MOSFETs from Alpha & Omega Semiconductor, designed for general-purpose switching and load control. It serves as a complementary device to N-Channel counterparts in bridge configurations. The series emphasizes low on-resistance and fast switching speeds suitable for modern portable electronic systems requiring efficient power regulation.
Replacement Considerations
Direct substitutes include AO3415A and AO3416, which share similar -20 V P-Channel specifications and SOT-23 packaging. Verify pinout compatibility and exact Rds(on) values before implementation to ensure circuit performance remains within design tolerances.
