PUMB14,115

Overview

The PUMB14,115 is a dual PNP resistor-equipped transistor manufactured by Nexperia USA Inc. It integrates two PNP transistors with built-in bias resistors in a compact SOT363 (SC-88) surface-mount package. The device features a collector-emitter voltage of -50 V and a continuous DC output current of -100 mA per transistor. The input bias resistor R1 has a typical value of 47 kΩ, while the second resistor R2 is left open. Total power dissipation is rated at 300 mW at an ambient temperature of 25 °C. The component operates within a junction temperature range up to 150 °C and supports reflow soldering processes.

Feature Summary

• Built-in bias resistors simplify circuit design and reduce component count
• Reduces pick and place costs during manufacturing
• Compact SOT363 plastic surface-mounted package

Applications

• Low current peripheral driver
• Control of IC inputs
• Replacement of general-purpose transistors in digital applications

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details. The -115 suffix corresponds to standard taping on a reel. Confirm RoHS compliance and halogen-free status through the manufacturer's latest product data sheet or environmental declaration before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring dual PNP switching with integrated base drive resistors. Ensure the required input resistance matches the fixed 47 kΩ typical value. Verify that the -50 V collector-emitter voltage rating meets the circuit requirements. Consider the 300 mW total power dissipation limit when designing thermal management strategies for the SOT363 package.

Part Context

The PUMB14 belongs to the PEMB14/PUMB14 family of PNP/PNP resistor-equipped transistors. It serves as the SC-88 packaged variant, complemented by the PEMD14 and PEMH14 models. This series is designed to replace discrete transistor networks, offering space savings and simplified assembly compared to using separate transistors and bias resistors in digital logic circuits.

Replacement Considerations

Publicly confirmed substitute part numbers include PUMD14 and PEMH14 from the same family.
