DTA114TMT2L

Overview

DTA114TMT2L is a PNP digital transistor manufactured by ROHM Semiconductor, featuring built-in bias resistors to simplify circuit design. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device utilizes an SOT-323 (VMT3) surface-mount package. Key electrical parameters include a typical input resistance of 10 kΩ, a minimum DC current gain (hFE) of 100 at -1 mA and -5 V, and a maximum operating frequency of 250 MHz. Power dissipation is rated at 150 mW, with a maximum junction temperature of +150 °C.

Feature Summary

• Integrates built-in bias resistors to eliminate the need for external input components in inverter circuits.
• Provides simplified on/off switching operation through integrated resistor networks.
• Designed for surface-mount assembly in compact electronic applications.

Applications

• Inverter circuits
• Interface logic driving
• General-purpose switching applications

Procurement Notes

Verify the specific suffix TMT2L against official ROHM documentation to confirm the exact reel packaging quantity and tape-and-reel specifications. Ensure compatibility with automated pick-and-place equipment requirements for the SOT-323 form factor. Cross-reference the RoHS compliance status and automotive qualification status if applicable to the target design environment.

Selection Notes

Select this component when a PNP digital transistor with a 10 kΩ input resistor is required in a small SOT-323 package. Compare the 150 mW power dissipation rating against thermal constraints. Verify that the -50 V collector-emitter voltage meets the circuit's supply requirements. Consider the complementary NPN type DTC114TMT2L for push-pull configurations.

Part Context

The DTA114T series represents ROHM's standard line of digital transistors with built-in bias resistors. These devices are designed to reduce board space and component count by integrating resistors directly with the transistor die. The TMT2L variant specifically denotes the SOT-323 package configuration within this family.

Replacement Considerations

Check for direct pin-compatible alternatives from other manufacturers offering similar PNP digital transistor characteristics in SOT-323 packages. Verify equivalent electrical parameters such as VCEO, IC, and hFE before substitution.
