DTC115TM3T5G

Overview

The DTC115TM3T5G is a PNP digital transistor manufactured by onsemi, belonging to the DTA115TM3 series. It integrates a single PNP bipolar junction transistor with built-in biasing resistors in a compact surface-mount package. The device is designed for switching applications requiring simplified circuit design by eliminating external base resistors. Key electrical characteristics include a collector-emitter voltage rating of 50 V and a continuous collector current capability of 100 mA. The component features an input resistance of approximately 100 kOhms and operates within a temperature range from -55°C to +150°C. It complies with RoHS standards and is supplied in tape and reel packaging.

Feature Summary

• Integrates a PNP transistor with internal biasing resistors to reduce external component count
• Designed for high-speed switching applications with simplified drive circuits
• Operates over an extended industrial temperature range up to 150°C

Applications

• General-purpose signal switching in consumer electronics
• Driver circuits for logic level translation
• Switching loads in portable battery-powered devices

Procurement Notes

Verify the specific ordering suffix T5G to confirm the reel packaging quantity and tape specifications required for automated assembly lines. Confirm RoHS compliance documentation is available for the specific manufacturing lot. Ensure the procurement channel provides genuine onsemi components to avoid counterfeit risks associated with small signal transistors.

Selection Notes

Select this PNP variant when the circuit design requires current sinking or negative logic switching configurations. Compare against NPN equivalents like the DTC115 series if positive logic switching is preferred. Verify that the 100 mA collector current and 50 V breakdown voltage meet the load requirements of the target application without exceeding thermal limits.

Part Context

This component is part of onsemi's broader portfolio of biased resistor transistors (BRTs). These devices consolidate discrete transistor and resistor functions into a single surface-mount package, facilitating space-constrained PCB layouts. The DTA115TM3 series specifically targets cost-sensitive and high-volume consumer applications where board real estate is limited.

Replacement Considerations

Direct pin-compatible substitutes may include other PNP digital transistors with similar 50V/100mA ratings and 100kOhm input resistance, such as parts from Rohm or STMicroelectronics, provided the package footprint matches exactly.
