UMY1N-TP

Overview

The UMY1N-TP is a dual bipolar junction transistor array manufactured by Micro Commercial Components, housed in a compact SOT-353 surface-mount package. It integrates one NPN and one PNP transistor within a single device to facilitate space-efficient circuit designs. The component supports a maximum collector-emitter voltage of 50V and a continuous collector current of 150mA. Key electrical characteristics include a transition frequency of 250MHz and a maximum power dissipation of 150mW. Internal base resistors are typically configured at 4.7kOhms with a ratio of 10, ensuring stable switching performance in digital logic applications.

Feature Summary

• Integrates complementary NPN and PNP transistors into a single compact package for simplified board layout
• Includes internal base resistors to reduce external component count and simplify driver interface requirements
• Designed for high-speed digital switching applications with a transition frequency of 250MHz
• Operates reliably across an extended temperature range from -55°C to +150°C

Applications

• Digital logic level shifting circuits
• Switching regulators and power management modules
• General-purpose signal switching and buffering
• Interface circuits between microcontrollers and peripheral devices

Procurement Notes

Verify the specific suffix designation when ordering, as variants such as UMY1N-TPHF may indicate halogen-free compliance. Confirm that the SOT-353 footprint matches the target PCB design, noting potential pinout differences compared to standard SOT-363 packages. Ensure the selected distributor provides official datasheets to validate the integrated resistor values and polarity configuration for the specific batch.

Selection Notes

Select this component when a mixed NPN/PNP pair is required in a minimal footprint. It serves as a direct replacement for discrete transistor pairs previously used in TTL or CMOS interfacing stages. Consider the 150mA current rating for low-power switching loads. Verify thermal management requirements, as the 150mW power dissipation limit constrains operation in high-density assemblies without adequate copper plane cooling.

Part Context

This part belongs to the UMY series of dual transistor arrays from Micro Commercial Components. It complements other series like UMH (dual NPN) and UMD (mixed NPN/PNP with different resistor configurations). The UMY1N-TP specifically targets applications requiring complementary symmetry in a small outline package, offering a cost-effective alternative to using two separate discrete transistors.

Replacement Considerations

• UMY1NTR (ROHM Semiconductor equivalent)
• UMD22NHE3-TP (MCC mixed pair, verify resistor values)
