UMG1NTR

Overview

The UMG1NTR is a dual NPN digital transistor manufactured by ROHM Semiconductor, housed in a compact SOT-353-5 (SC-88A) surface-mount package. It integrates two NPN transistors with built-in bias resistors configured for common emitter operation. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The device features a typical input resistance of 22 kOhms with a resistor ratio of 1, ensuring simplified circuit design. It offers a minimum DC current gain (hFE) of 56 at 5 mA and 5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, and the unit supports an operating temperature range up to +150°C.

Feature Summary

• Integrates dual NPN transistors with built-in bias resistors to reduce external component count and simplify digital circuit design.

• Utilizes a small SOT-353-5 surface-mount package to facilitate space-constrained PCB layouts.

Applications

• General-purpose digital logic interface circuits
• High-frequency switching applications
• Automotive electronics systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical tolerances. Ensure that the procurement channel provides authentic components with traceable documentation to meet quality standards. Confirm RoHS compliance status if required by regulatory frameworks. Check for any end-of-life notifications or recommended alternative part numbers before finalizing purchase orders.

Selection Notes

Select the UMG1NTR when a dual NPN configuration with integrated biasing is required for space-efficient designs. The 22 kOhm input resistance suits standard logic levels, while the 50 V rating provides adequate headroom for low-voltage digital systems. Consider the 150 mW power dissipation limit and thermal management requirements for dense packaging environments. Evaluate the 250 MHz frequency response against signal speed requirements to ensure adequate performance margins.

Part Context

The UMG1NTR belongs to the UMG1N series of general-purpose dual digital transistors from ROHM Semiconductor. This series is designed to replace multiple discrete components by integrating transistors and bias resistors into a single package. The UMG1N variant specifically denotes the 22 kOhm input resistance configuration within this family, distinguishing it from other variants with different resistance values.

Replacement Considerations
