DTC113ZU3T106

Overview

The DTC113ZU3T106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323 (UMT3) surface-mount package. It integrates biasing resistors with typical values of R1 = 1 kΩ and R2 = 10 kΩ, yielding a resistance ratio of 10. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 33 at -5 mA/-5 V, a maximum operating frequency of 250 MHz, and a power dissipation rating of 200 mW. The saturation voltage is specified at -300 mV, with an emitter-base voltage (VEBO) limit of -3 V.

Feature Summary

• Integrates built-in biasing resistors to simplify circuit design by eliminating the need for external input resistors.
• Enables direct configuration of inverter circuits within compact surface-mount footprints.
• Provides high-speed switching capabilities suitable for digital logic applications.

Applications

• Inverter circuits requiring compact pre-biased transistor solutions
• Digital logic interface and level shifting applications
• General-purpose switching in consumer electronics

Procurement Notes

Verify component authenticity through authorized distribution channels or official manufacturer documentation. Confirm that the ordering suffix matches the specific tape-and-reel packaging requirements for automated assembly processes. Ensure compliance with RoHS directives and check for AEC-Q101 automotive qualification status if applicable to the target end-use environment.

Selection Notes

Select this component when a single NPN digital transistor with a 1 kΩ base resistor is required in an SOT-323 package. Consider the 200 mW power dissipation limit and -50 V voltage rating against circuit demands. Compare against similar models like DTC114ZU3 for different resistance ratios or DTC113ZCAHZGT116 for automotive-grade specifications.

Part Context

This part belongs to the ROHM DTC113 series of pre-biased transistors, designed for space-constrained digital applications. The U3 suffix indicates the SOT-323/UMT3 package type, while T106 denotes the specific reel packaging format. It serves as a standard discrete solution for replacing multiple discrete components in low-power switching tasks.

Replacement Considerations

Direct pin-compatible substitutes include DTC113ZU3 (same electrical specs, verify packaging suffix) and DTC113ZCAT116 (SST3 package). For automotive applications, consider DTC113ZU3HZGT106 which holds AEC-Q101 certification. Verify thermal performance and resistance tolerances when cross-referencing with other manufacturers' equivalents.
