DTC115TCAT116

Overview

The DTC115TCAT116 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates a bias resistor network to simplify circuit design. Key electrical parameters include a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. The device features a typical input resistance of 100 kOhms and achieves a minimum DC current gain (hFE) of 100 at 1 mA and 5 V. It supports a maximum operating frequency of 250 MHz with a power dissipation rating of 200 mW. The component operates within a temperature range up to +150°C and complies with RoHS standards.

Feature Summary

• Integrates built-in bias resistors to eliminate the need for external input components, enabling straightforward inverter circuit configuration.
• Provides high-speed switching capabilities suitable for applications requiring operation up to 250 MHz.
• Offers compact surface-mount packaging to facilitate automated assembly and space-constrained board layouts.

Applications

• Inverter circuits for logic level translation
• Driver stages for relays and solenoids
• Switching applications in consumer electronics

Procurement Notes

Verify the complete part number including the AT116 suffix to ensure correct tape-and-reel packaging specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain component integrity during handling and soldering processes.

Selection Notes

Select this component when a single NPN digital transistor with a 100 kOhm base resistor is required. Compare against complementary PNP types like the DTA115TCAT116 for push-pull configurations. Evaluate thermal performance based on the 200 mW power dissipation limit and verify that the 50 V voltage rating meets the specific circuit requirements.

Part Context

This part belongs to the DTC115 series of pre-biased transistors from ROHM Semiconductor. It shares functional similarities with variants such as DTC114TCA but differs in internal resistor values. The AT116 suffix denotes specific packaging and handling characteristics distinct from other reel options within the same product family.

Replacement Considerations

Direct substitutes include the DTC115TCA without the trailing suffix if packaging compatibility is verified. For complementary polarity needs, consider the DTA115TCAT116. Alternative packages like SOT-416 require mechanical adaptation despite similar electrical profiles.
