Overview
The PUMB18,115 is a dual PNP resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates two PNP transistors with built-in bias resistors into a single SOT-363 (SC-88) surface-mounted package. The device features a collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA per transistor. The typical input bias resistor (R1) is 4.7 kΩ, with a bias resistor ratio (R2/R1) of 2.1. Total power dissipation is rated at 200 mW per transistor and 300 mW for the entire device at an ambient temperature of 25 °C. The component operates within a junction temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates two PNP transistors with built-in bias resistors in a compact SOT-363 package.
- Reduces printed circuit board area and pick-and-place costs compared to discrete components.
- Simplifies circuit design through integrated biasing networks.
- Qualified according to AEC-Q101 standards for automotive applications.
Applications
- Low current peripheral driver circuits
- Control of IC inputs
- Replacement for general-purpose transistors in digital applications

Selection Notes
Select the PUMB18 when space-constrained designs require dual PNP switching with integrated biasing. Ensure the required collector current does not exceed 100 mA and that the -50 V voltage rating accommodates the circuit's maximum operating conditions. Verify thermal management requirements against the 200 mW per-transistor dissipation limit.
Part Context
The PUMB18 belongs to the PEMB18/PUMB18 family of PNP resistor-equipped transistors. While the PEMB18 utilizes the larger SOT-666 package, the PUMB18 employs the smaller SOT-363 (SC-88) footprint. Both variants share identical electrical characteristics, including the 4.7 kΩ input resistor and 50 V voltage rating, allowing for pin-compatible or functionally equivalent design choices based on available PCB real estate.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult official Nexperia replacement guides or datasheets for cross-reference information.
