Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against the official ROHM datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to procurement. Ensure the component designation matches the exact part number required for the design specification.

Single Bipolar Transistors Selection Notes

Select this component when a dual NPN digital transistor with integrated base resistors is required. Verify that the 50V voltage rating and 30mA continuous current capacity meet the circuit requirements. Consider the TUMT-6 package dimensions for PCB layout constraints and ensure the operating temperature range aligns with the environmental conditions of the target application.

Single Bipolar Transistors Part Context

This component belongs to the UMH6N series of digital transistors manufactured by ROHM Semiconductor. These devices integrate NPN transistors with built-in bias resistors to reduce external component count. The UML6NTR variant specifically utilizes the TUMT-6 package, offering a compact solution for space-constrained designs while maintaining standard digital transistor functionality.

Single Bipolar Transistors Replacement Considerations

Consult the official ROHM replacement guide for verified substitute part numbers. Cross-reference pinout compatibility and electrical parameters such as VCEO and hfe before substituting. Generic equivalents may not match the integrated resistor ratios or package dimensions.
