UMG3N-TP

Overview

The UMG3N-TP is a complex digital transistor from Micro Commercial Components, integrating two NPN transistors within a single SOT-353 (UMT5) surface-mount package. This dual configuration provides a compact solution for differential amplifier circuits and high-frequency applications such as crystal oscillators. The device features a supply voltage of 1V and supports a collector current of 0.1A per channel. It includes integrated input resistors with typical values of 1kΩ and 4.7kΩ, offering a resistor ratio of 10. Designed for robust operation, it withstands storage temperatures ranging from -55°C to +150°C and is supplied in tape-and-reel packaging with a standard quantity of 3000 units.

Feature Summary

• Integrates two NPN transistors into a single ultra-small SOT-353 package for space-efficient designs.
• Includes built-in input resistors to simplify biasing networks and reduce external component count.
• Supports low-voltage operation with a 1V supply capability suitable for portable electronics.

Applications

• Differential amplifier circuits requiring matched transistor pairs.
• High-frequency crystal oscillator starter stages.
• General-purpose switching applications in compact consumer devices.

Procurement Notes

Verify the specific suffix requirements for RoHS compliance and halogen-free status before ordering, as manufacturing variations may exist. Confirm that the SOT-353 footprint matches your PCB design constraints. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a dual NPN configuration is required in a minimal footprint. Compare its 0.1A current rating against load requirements. Verify that the integrated resistor values meet the circuit's biasing needs without external components. Consider thermal dissipation limits in dense layouts.

Part Context

This part belongs to MCC's UMG series of complex digital transistors. It serves as an alternative to discrete transistor pairs, simplifying assembly. The SOT-353 package is common in mobile and handheld devices where board space is limited. It complements other pre-biased transistor arrays in the manufacturer's portfolio.

Replacement Considerations

The DTc143t is listed as an equivalent single-part reference. For direct dual-transistor replacement, verify pinout compatibility with existing designs. Check if alternative suppliers offer identical SOT-353 dual NPN packages with matching electrical characteristics.
