DTA115TCAT116

Overview

The DTA115TCAT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SOT-23-3 surface-mount package. It integrates a bias resistor with a typical value of 100 kOhms to simplify circuit design. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA. Key electrical characteristics include a minimum DC current gain (hFE) of 100 at -1 mA and -5 V, a transition frequency of 250 MHz, and a power dissipation rating of 350 mW. It operates within a temperature range up to +150 C.

Feature Summary

• Integrates a built-in bias resistor to eliminate the need for external input resistors, simplifying inverter circuit configuration.
• Designed for high-speed switching applications with a maximum operating frequency of 250 MHz.
• Provides robust performance with a high DC current gain and low saturation voltage for efficient signal processing.

Applications

• Inverter circuits requiring simplified input stages
• Interface drivers for logic level translation
• General-purpose switching applications in consumer electronics

Procurement Notes

Verify the specific ordering suffix 'T116' against the manufacturer's datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure compatibility with automated pick-and-place equipment regarding the SOT-23-3 footprint. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with a 100 kOhm base resistor is required in a compact SOT-23-3 package. Compare the -50 V voltage rating and -100 mA current capacity against circuit demands. Consider complementary NPN models like the DTC115TCAT116 for push-pull configurations or balanced design pairs.

Part Context

This part belongs to the DTx series of digital transistors from ROHM Semiconductor, which are designed to replace discrete resistor-transistor networks. The DTA115 variant specifically denotes a PNP polarity with a 100 kOhm internal resistor. The T116 suffix indicates the specific taping and reeling format used for mass production and surface-mount assembly processes.

Replacement Considerations

Direct pin-compatible substitutes include other ROHM parts such as DTA115TCA without the T116 suffix, provided packaging differences are acceptable. External distributors may list equivalent parts from other manufacturers, but electrical parameters must be verified against the original datasheet to ensure functional equivalence.
