DTA115TUAT106

Overview

The DTA115TUAT106 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 surface-mount package. It features a built-in bias resistor with a typical input resistance of 100 kOhms. The device supports a maximum 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 100 at -1 mA and -5 V, a power dissipation rating of 350 mW, and a maximum operating frequency of 250 MHz. The emitter-base voltage (VEBO) is rated at -5 V, and the component operates within a temperature range up to +150 C.

Feature Summary

• Integrates a 100 kOhm bias resistor to eliminate external input components for inverter circuit configuration.
• Provides simplified circuit design by requiring only on/off condition settings for operation.
• Offers high-speed switching capability suitable for interface and driver applications.

Applications

• Inverter circuits
• Interface logic circuits
• Driver stages

Procurement Notes

Verify the specific suffix AT106 against the official datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the order matches the required quantity multiples defined by the manufacturer's standard packing format. Cross-reference the RoHS compliance status directly from the product documentation before finalizing procurement decisions.

Selection Notes

Select this component when a PNP digital transistor with a 100 kOhm input resistor is required in an SOT-323-3 package. Compare the 350 mW power dissipation and -50 V voltage rating against circuit requirements. Consider the complementary NPN model DTC115T series if a matched pair is needed for push-pull configurations.

Part Context

This part belongs to the DTA115TUA series of digital transistors from ROHM Semiconductor. These devices are designed as standalone solutions for replacing discrete resistor-transistor combinations. The series focuses on reducing board space and simplifying assembly by integrating biasing networks directly into the semiconductor package.
