The PUML1,115 is a PNP transistor manufactured by NXP USA Inc., designed for general-purpose switching and amplification applications. It features a maximum collector-emitter voltage of -40 V and a continuous collector current rating of 100 mA. The device operates within a junction temperature range of -55 °C to +150 °C and is housed in an SOT-323 surface-mount package. It complies with RoHS directives and is classified under EAR99 export control codes.
Verify the specific ordering code suffix to ensure correct tape-and-reel quantities and packaging variants. Confirm that the component meets the required environmental standards for the intended deployment environment. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with current design specifications and lead-free manufacturing processes.
Select this component when a compact PNP transistor is required for low-current switching tasks. Ensure the circuit design accommodates the -40 V voltage limit and 100 mA current capacity. Consider the thermal management requirements given the small SOT-323 footprint and the specified operating temperature range for reliable long-term performance.
This part belongs to NXP's portfolio of discrete semiconductor devices, specifically focusing on small-signal transistors. It serves as a fundamental building block for analog and digital circuits where space constraints necessitate miniature surface-mount packages like SOT-323.
Consult official substitution guides for compatible PNP transistors in SOT-323 packages with similar electrical ratings. Verify pinout compatibility and thermal characteristics before implementing any alternative components.
