PUMB9,115

Overview

The PUMB9,115 is a dual pre-biased NPN digital transistor manufactured by Nexperia USA Inc. It integrates two NPN transistors with built-in base resistors into a single SOT-363 (SC-88) surface-mount package. The device features a collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Each transistor includes a typical input resistor of 10 kOhms with a resistance ratio of 0.2. Designed for operation between -65 °C and +150 °C, it supports peak DC collector currents up to 100 mA and is available in reel, cut tape, and MouseReel packaging formats.

Feature Summary

• Dual NPN configuration with integrated base biasing resistors
• Compact SMD footprint suitable for space-constrained designs
• High thermal stability across extended temperature ranges

Applications

• General-purpose switching circuits
• Logic level translation interfaces
• Driver stages for low-power loads

Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm exact packaging and reel specifications. Ensure compatibility with standard SMT reflow profiles for the SOT-363 package. Confirm RoHS compliance status through the manufacturer's latest declaration before finalizing procurement orders.

Selection Notes

Select this component when a compact dual NPN solution with fixed biasing is required. The 10 kOhm input resistor simplifies circuit design by eliminating external base components. Verify that the 50 V voltage rating and 100 mA current limits meet the specific application requirements.

Part Context

This part belongs to the Nexperia PUM series of resistor-equipped transistors. These devices are designed to replace multiple discrete components, reducing board space and assembly costs. The PUMB9 variant specifically provides dual NPN configurations within the widely used SC-88 form factor.

Replacement Considerations

Check for direct equivalents such as the PUMD9 or other PUM-series variants from Nexperia. Verify pinout compatibility and electrical parameter alignment before substituting with parts from other manufacturers.
