DTA114ESA-BP

Overview

The DTA114ESA-BP is a PNP digital transistor manufactured by Micro Commercial Components (MCC) in the TO-92S package. It integrates thin-film bias resistors to enable inverter circuit configuration without external input components. 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 internal base resistor (R1) of 10 kΩ with a resistance ratio (R2/R1) of 1.0, a minimum DC current gain of 30, and a transition frequency of 250 MHz.

Feature Summary

• Built-in bias resistors facilitate simple inverter circuit design by eliminating the need for external input resistors.
• Integrated thin-film resistors provide complete isolation to minimize parasitic effects and allow negative input biasing.
• Operation requires setting only On/Off conditions, simplifying device integration.

Applications

• Inverter circuits
• Switching applications
• Driver circuits

Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit parts. Confirm the BP suffix indicates bulk packaging containing 100,000 pieces per carton. Ensure compliance with RoHS standards as designated by the 'P' suffix. Check for specific halogen-free requirements using the '-HF' suffix if necessary.

Selection Notes

Select this component for designs requiring a PNP digital transistor with integrated biasing in a TO-92S through-hole package. Consider the 300 mW power dissipation limit and -50 V maximum voltage rating when designing the circuit. Verify that the 10 kΩ internal base resistance aligns with the required drive characteristics.

Part Context
