PBRN113ZK,115

Overview

The PBRN113ZK,115 is an NPN Breakthrough In Small Signal (BISS) Resistor-Equipped Transistor from the Nexperia PBRN113Z series. It features a collector-emitter voltage of 40 V and an output current capability of 600 mA in the SOT346 package. The device integrates bias resistors with R1 at 1 kΩ and R2 at 10 kΩ, providing a nominal ratio of 10. Key electrical characteristics include a DC current gain ranging from 300 to 750 depending on collector current, and a low collector-emitter saturation voltage. The component operates within a junction temperature range up to 150 °C and is housed in a SC-59A plastic surface-mounted package.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status database, as availability may vary. Confirm that the SOT346 package dimensions match the target PCB footprint requirements before finalizing procurement decisions. Ensure compliance with RoHS directives if required by the end application specifications.

Selection Notes

Select this component when a compact NPN transistor with integrated base biasing is required for medium-current switching tasks. The 1 kΩ input resistor value determines the necessary drive current from the control logic. Consider the thermal resistance characteristics and power derating curves if operating near maximum current limits or in enclosed environments.

Part Context

This part belongs to the PBRN113Z family of BISS RETs, which includes variants in different packages such as SOT54 and SOT23. The 'K' suffix specifically denotes the SOT346 (SC-59A) surface-mount package. The '115' suffix indicates tape and reel packaging suitable for automated pick-and-place assembly processes.

Replacement Considerations

Direct replacements must maintain the NPN configuration, 40V VCEO rating, 600mA+ IO capability, and the 1kΩ/10kΩ bias resistor network. Verify pinout compatibility between SOT346 and alternative packages like SOT23 or SOT54 if physical space constraints allow for package changes.
