UMH11N-13P

Overview

The UMH11N-13P is a dual NPN digital transistor array manufactured by Micro Commercial Components (MCC). It integrates two pre-biased NPN transistors within a compact SOT-363 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50V and a continuous collector current of 50mA. The device features an internal base resistor of 10 kOhms and an emitter resistor of 10 kOhms, resulting in a typical resistance ratio of 1. It offers a minimum DC current gain (hFE) of 30 at 5mA and 5V, with a transition frequency of 250MHz. Power dissipation is rated at 150mW, and the saturation voltage is specified at 300mV under defined test conditions.

Procurement Notes

Verify the specific ordering suffix against official MCC documentation to ensure correct packaging configuration. Confirm that the component meets required RoHS and REACH compliance standards for the target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required to reduce external component count. Ensure the 50V voltage rating and 50mA current capacity align with the application's load requirements. Consider the SOT-363 footprint constraints during PCB layout and verify thermal management needs given the 150mW power dissipation limit.

Part Context

This component belongs to the UMH11 series of digital transistor arrays from Micro Commercial Components. It is designed as a replacement for discrete resistor-transistor networks, offering a simplified solution for switching applications. The series typically includes variants with different resistor values to accommodate various drive requirements while maintaining the same physical footprint and electrical characteristics.

Replacement Considerations

Check for direct equivalents such as the UMH11N-TP variant, which shares identical electrical specifications and pinout. Verify compatibility with other manufacturers' dual NPN digital transistors in the SOT-363 package, ensuring matching voltage, current, and resistor values.
