IMH21T110

Overview

The IMH21T110 is a dual NPN pre-biased digital transistor from ROHM Semiconductor, housed in an SMT-6 surface-mount package. It features a maximum collector-emitter voltage of 20V and a continuous collector current rating of 600mA. The device supports a maximum operating frequency of 150MHz with a power dissipation capacity of 300mW. Internal biasing resistors simplify circuit design by reducing component count.

Feature Summary

• Integrates two NPN transistors with built-in biasing resistors for simplified switching applications
• Optimized for high-speed operation with a 150MHz maximum frequency rating
• Designed for compact surface-mount integration to minimize PCB footprint

Applications

• General-purpose signal switching circuits
• Driver stages for low-power loads
• Logic interface buffering

Procurement Notes

Verify the specific suffix against the official ROHM datasheet to confirm pinout compatibility and electrical tolerances. Ensure the procurement channel provides authentic components with traceable documentation. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity before purchase.

Selection Notes

Select this component when a dual NPN configuration with integrated biasing is required for space-constrained designs. Evaluate the 20V voltage limit and 600mA current capability against load requirements. Consider the SMT-6 package dimensions for board layout constraints and thermal management needs during selection.

Part Context

This device belongs to ROHM's digital transistor series, which combines bipolar junction transistors with internal resistors. These components replace discrete resistor-transistor networks, offering improved reliability and reduced assembly complexity in modern electronic systems requiring efficient switching solutions.

Replacement Considerations

Consult the official ROHM replacement guide for verified equivalents. Verify that any substitute maintains identical pinout configurations and electrical specifications to ensure direct compatibility without circuit redesign.
