PBRN123EK,115

Overview

The PBRN123EK,115 is an NPN Resistor-Equipped Transistor (RET) from the BISS family, housed in a SOT346 (SC-59A/TO-236) surface-mount package. It integrates bias resistors R1 and R2 with a typical value of 2.2 kΩ each and a ratio tolerance of ±10%. The device supports a collector-emitter voltage (VCEO) of 40 V and a continuous output current (IO) of 600 mA. Total power dissipation reaches 250 mW at 25 °C ambient temperature. Key electrical characteristics include a DC current gain (hFE) ranging from 70 to 560 depending on collector current, and a low collector-emitter saturation voltage.

Feature Summary

• Integrates built-in bias resistors to simplify circuit design and reduce component count.
• Features low collector-emitter saturation voltage for efficient switching performance.
• Provides high current gain suitable for digital applications in automotive and industrial segments.
• Offers ±10% resistor ratio tolerance for consistent biasing.

Applications

• Digital applications in automotive and industrial segments
• Switching loads
• Medium current peripheral driver

Procurement Notes

Verify the specific ordering suffix '115' against manufacturer documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and manufacturing origin details prior to procurement. Ensure compatibility with standard SMT pick-and-place processes for the SOT346 package.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for medium-current switching. The SOT346 package is appropriate for space-constrained PCB layouts. Consider the 600 mA continuous current limit and 40 V voltage rating to ensure operation within absolute maximum ratings under all expected load conditions.

Part Context

This part belongs to the PBRN123E series of NPN Resistor-Equipped Transistors manufactured by Nexperia. The series includes variants in different packages such as SOT54 and SOT23. The PBRN123EK specifically utilizes the SOT346 plastic surface-mounted package configuration.

Replacement Considerations

PBRN123ET is a functional substitute within the same series using the SOT23 package. PBRN123ES serves as a through-hole alternative in the SOT54 package. Verify pinout compatibility and thermal dissipation requirements when substituting between these package types.
