DTC323TKT146

Overview

The DTC323TKT146 is a single NPN pre-biased bipolar transistor manufactured by ROHM Semiconductor. It features a collector-emitter maximum voltage of 15 V and a continuous collector current of 600 mA. The device operates with a maximum frequency of 200 MHz and has a power dissipation rating of 200 mW. Packaged in an SMT3 (SOT-346) surface-mount case, it integrates internal biasing resistors to simplify circuit design.

Feature Summary

• Integrates built-in biasing resistors for simplified circuit configuration
• Supports high-speed switching applications up to 200 MHz
• Designed for surface-mount assembly in compact SMT3 packages

Applications

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

Procurement Notes

Verify the specific suffix T146 against the official ROHM datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a single NPN digital transistor with integrated biasing is required for space-constrained designs. The 600 mA current capacity suits moderate load driving tasks. Consider the 15 V voltage limit for low-voltage logic systems. The SMT3 package offers a small footprint suitable for high-density PCB layouts requiring surface-mount technology.
