Overview
The Nexperia PUMH11/ZLX is a dual NPN resistor-equipped transistor (RET) housed in a SOT363 surface-mount package. It integrates two NPN transistors with built-in bias resistors, where R1 is typically 10 kΩ and the R2/R1 ratio is 1. The device supports a maximum collector-emitter voltage of 50 V and an output current of 100 mA per transistor. Total power dissipation is rated at 300 mW for the device and 200 mW per transistor at 25 °C ambient temperature. It features a junction-to-ambient thermal resistance of 417 K/W and operates within an ambient temperature range of -65 °C to +150 °C.
Feature Summary
- Integrates dual NPN transistors with built-in bias resistors to reduce component count and simplify circuit design.
- AEC-Q101 qualified for automotive applications.
- Optimized for low voltage collector-emitter saturation.
Applications
- Low current peripheral driver
- Control of IC inputs
- Replaces general-purpose transistors in digital applications
Procurement Notes
Verify the specific suffix ZLX against official Nexperia documentation to confirm manufacturing site or tape-and-reel specifications. Ensure the ordering code matches the required packing method, such as 4 mm pitch tape and reel. Confirm RoHS compliance and REACH status prior to procurement.
Selection Notes
Select this component when space-constrained designs require dual NPN switching with integrated base biasing. The SOT363 package offers a very small footprint suitable for high-density PCB layouts. Verify that the 10 kΩ input resistor value aligns with the driving source impedance requirements.
Part Context
The PUMH11 belongs to the PUMH series of NPN/NPN resistor-equipped transistors. It shares the same electrical characteristics as the PEMH11 but utilizes the SOT363 (SC-88) package instead of the SOT666 package. This series is designed to replace discrete transistor and resistor networks in digital logic circuits.
