UMH5NTR

Overview

The UMH5NTR is a dual NPN digital transistor manufactured by ROHM Semiconductor, housed in a compact SMD/SMT package. It features a typical input resistance of 10 kOhms and a typical resistor ratio of 2. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 30 mA. Key electrical parameters include a minimum DC collector/base gain (hfe) of 68 at 10 mA and 5 V, with a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, and the unit operates within a temperature range of -55°C to +150°C.

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, as specified in the official datasheet. Confirm RoHS compliance status and lead times directly with the supplier prior to procurement to align with production schedules.

Selection Notes

Select this component when a dual NPN configuration with integrated base resistors is required for space-constrained designs. The 10 kOhm input resistance offers a balance between drive current requirements and noise immunity. Verify that the 50 V voltage rating and 30 mA current capacity meet the specific load conditions of the target application circuit.

Part Context

The UMH5NTR belongs to the UMH series of complex transistors from ROHM Semiconductor. This series integrates pre-biased resistors with bipolar junction transistors to reduce external component count.
