UMF17NTR

Overview

The UMF17NTR is a pre-biased bipolar transistor array manufactured by ROHM Semiconductor. It integrates one NPN and one PNP transistor within a single surface-mount package. The device features a maximum collector-emitter voltage of 50V for the NPN section and supports continuous collector currents up to 100mA for NPN and 150mA for PNP configurations. Operating frequencies reach 250MHz for the NPN element and 140MHz for the PNP element. Power dissipation is rated at 150mW, with an internal base resistor (R1) of 2.2kOhms.

Feature Summary

• Integrates complementary NPN and PNP transistors in a single compact package
• Includes built-in base resistors to simplify circuit design
• Supports high-speed switching applications with specified frequency ratings
• Designed for surface-mount technology assembly

Applications

• General-purpose switching circuits
• Logic interface buffers
• Driver stages for small loads

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as reel or cut tape availability. Ensure storage conditions adhere to moisture sensitivity level requirements. Cross-reference part numbers to avoid confusion with similar series components. Validate technical specifications against current datasheets before integration.

Selection Notes

Select this component when space-constrained designs require both NPN and PNP switching capabilities. Consider the 50V voltage rating and current limits for load compatibility. Evaluate the 150mW power dissipation against thermal management constraints. Compare frequency responses if high-speed operation is critical. Verify package dimensions match PCB footprint requirements.

Part Context

This component belongs to ROHM's pre-biased transistor array series, designed to replace discrete resistor-transistor networks.
