DTA115EUBTL

Overview

The DTA115EUBTL is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323FL-3 surface-mount package. It integrates biasing resistors with typical values of 100 kOhms for both R1 and R2, maintaining a ratio of 1. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW. The device features a minimum DC current gain (hFE) of 82 at -5 mA and -5 V, with a maximum operating frequency of 250 MHz. It operates within a temperature range up to +150°C.

Feature Summary

• Integrates built-in bias resistors to eliminate external input components for inverter circuit configuration.
• Simplifies circuit design by requiring only on/off condition settings for operation.
• Provides high-speed switching capabilities suitable for interface and driver applications.

Applications

• Inverter circuits
• Interface circuits
• Driver circuits

Procurement Notes

Verify the specific suffix 'UBTL' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and handling specifications. Ensure compatibility with standard SMD/SMT assembly processes. Confirm RoHS compliance status through the latest regulatory documentation provided by ROHM Semiconductor before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with 100 kOhm internal biasing resistors is required in a compact SOT-323FL-3 package. Consider the -50 V voltage rating and -100 mA current capacity for appropriate load matching. Verify that the 200 mW power dissipation limit aligns with the thermal management requirements of the target application environment.
