UMH15N-TP

Overview

The UMH15N-TP is a dual NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates two NPN transistors with built-in biasing resistors in a compact SOT-363 surface-mount package. The device features a collector-emitter breakdown voltage of 50V and a continuous collector current rating of 100mA. Each transistor includes a base resistor (R1) of 22 kOhms and an emitter resistor (R2) of 22 kOhms, providing a typical resistance ratio of 1. Key electrical characteristics include a minimum DC current gain (hFE) of 56 at 5mA and 5V, a maximum saturation voltage of 300mV at specified currents, and a transition frequency of 250MHz. The component supports operation within a temperature range of -55°C to +150°C with a power dissipation of 150mW.

Procurement Notes

Verify the specific ordering suffix and packaging configuration directly with authorized distributors or the manufacturer before procurement. Confirm that the delivered components match the exact part number UMH15N-TP to ensure compatibility with the intended design specifications. Check for any recent product change notices regarding assembly sites or material compositions.

Selection Notes

Select the UMH15N-TP when a dual NPN configuration with equal base and emitter resistances is required. Ensure the application demands a 50V voltage rating and 100mA current capacity. Consider this component for designs prioritizing board space reduction through integrated biasing networks while maintaining standard logic interface compatibility.

Part Context

This component belongs to the UMH series of digital transistors from Micro Commercial Components. It shares the SOT-363 form factor with other variants in the lineup but differs in internal resistor values and specific electrical parameters. The series is designed to replace discrete resistor-transistor combinations, offering a standardized solution for embedded systems and portable devices.

Replacement Considerations

Direct substitutes may include other dual NPN digital transistors in SOT-363 packages with similar 50V ratings and 22k/22k resistor configurations. Verify pinout compatibility and electrical limits before substitution. Cross-reference with equivalent parts from other manufacturers ensuring identical functional characteristics.
