DTC123YCAHZGT116

Overview

The DTC123YCAHZGT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It features built-in biasing resistors with typical values of R1 = 2.2 kΩ and R2 = 10 kΩ, yielding a resistor ratio of 21. The device supports a maximum collector current of 100 mA and operates up to a transition frequency of 250 MHz. Key electrical limits include a collector-emitter voltage (VCEO) of 30 V, an emitter-base voltage (VEBO) of 1.1 V, and a power dissipation rating of 350 mW. It meets AEC-Q101 automotive qualification standards.

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Ensure the ordering suffix matches the required tape-and-reel packaging configuration. Cross-reference the specific part number against official ROHM databases to confirm current production status and compliance with RoHS directives before finalizing procurement plans.

Selection Notes

Select this component when a compact NPN solution with integrated base resistance is required for space-constrained designs. The 2.2 kΩ input resistor value suits applications needing moderate drive currents. Verify that the 30 V collector-emitter voltage rating aligns with the target circuit's supply levels and signal swings to ensure safe operation within specified thermal limits.

Part Context

This part belongs to the DTC123 series of pre-biased transistors from ROHM. It serves as the NPN counterpart to PNP variants like the DTA123YCAHZGT116. The series is engineered for automotive-grade reliability, offering a compact alternative to discrete transistor-resistor combinations in modern electronic assemblies.

Replacement Considerations

Direct functional substitutes within the same family include DTC123JCAHZGT116, which shares the SOT-23 package but differs in resistor ratios and gain characteristics. Designers must verify pin compatibility and electrical parameter alignment when considering cross-model replacements.
