Overview
The MMBT4403 is a 600mA Silicon PNP Epitaxial Planar Transistor manufactured by ANBON SEMICONDUCTOR (INT'L) LIMITED. It operates with a maximum collector-base voltage of -40V, a collector-emitter voltage of -40V, and an emitter-base voltage of -5.0V. The device supports a continuous collector current of -600mA and dissipates up to 225mW on an FR-5 board or 300mW on an alumina substrate. It functions within a storage temperature range of -55°C to +150°C and an operating junction temperature range of -55°C to +150°C.
Feature Summary
- Epitaxial planar chip construction for reliable switching and amplifier performance.
- Lead-free composition exceeding MIL-STD-19500/228 environmental standards.
- UL94-V0 rated flame retardant epoxy in a molded plastic SOT-23 case.
Applications
- Medium power applications
- Switching circuits
Procurement Notes
Verify the specific ordering suffix against the manufacturer's documentation before procurement. Confirm that the component matches the required lead-free specifications if environmental compliance is mandatory. Ensure the package type aligns with the intended surface mount assembly process. Cross-reference the datasheet revision date to confirm the accuracy of the electrical parameters provided.
Selection Notes
Select this component for designs requiring a general-purpose PNP transistor in a compact SOT-23 footprint. Consider the complementary NPN type for paired circuit requirements. Evaluate thermal management needs based on the specified dissipation limits on standard FR-5 substrates. Verify that the saturation voltages meet the efficiency requirements of the target switching application.
Part Context
This component belongs to the family of small-signal bipolar junction transistors designed for low-power electronic systems. It utilizes silicon technology to provide stable amplification and switching capabilities. The epitaxial planar structure ensures consistent performance across varying operational temperatures and load conditions.
Replacement Considerations
The datasheet recommends the NPN transistor MMBT4401 as the complementary type. No other direct substitute part numbers are documented in the provided source material.
