DTA114ESA-AP

Overview

The DTA114ESA-AP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in a TO-92S package. It integrates built-in thin-film bias resistors to simplify circuit design. Key electrical parameters include a maximum supply voltage of -50 V, a continuous output current of -100 mA, and a power dissipation of 300 mW. The device features an input resistance (R1) of 10 kΩ with a typical range of 7.0 to 13 kΩ, and a resistance ratio (R2/R1) of 1.0. It operates within a junction temperature range of -55°C to 150°C and has a transition frequency of 250 MHz.

Feature Summary

• Built-in bias resistors enable inverter configuration without external input components
• Thin-film resistors provide complete isolation to eliminate parasitic effects
• Moisture sensitivity level 1 certification for reliable handling
• Epoxy meets UL 94 V-0 flammability rating

Applications

• Inverter circuits
• Interface applications
• Driver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging type and compliance status. The -AP suffix indicates ammo packing, while other suffixes may denote bulk or halogen-free variants. Ensure procurement from authorized distributors to guarantee part authenticity and traceability as per MCC guidelines.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required in a through-hole TO-92S package. Consider the 300 mW power dissipation limit and -50 V voltage rating during thermal and electrical design. Verify that the 10 kΩ input resistance aligns with the driving source requirements for the intended logic interface.

Part Context

The DTA114ESA belongs to the DTA114 series of pre-biased PNP transistors produced by Micro Commercial Components. This series is designed to replace discrete resistor-transistor networks, reducing board space and assembly complexity. The TO-92S package distinguishes it from surface-mount counterparts like the SOT-23 variants found in the same product family.

Replacement Considerations

Cross-reference with other PNP digital transistors offering similar -50V ratings and integrated biasing. Verify pinout compatibility for the TO-92S package and ensure equivalent electrical characteristics such as DC current gain and transition frequency are met for direct substitution.
