DTA114ECAHE3-TP

Overview

The DTA114ECAHE3-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates internal biasing resistors within an SOT-23 surface-mount package. The device features a collector-emitter maximum voltage of -50 V and a continuous collector current of -100 mA. Typical base resistance is 10 kOhms with a resistor ratio of 1. The DC current gain (hFE) minimum is 30 at 5 mA and 5 V. Power dissipation is rated at 200 mW, with an operating temperature range from -55 C to +150 C. The component holds AEC-Q101 qualification for automotive applications.

Feature Summary

• Integrated pre-biased resistor network simplifies circuit design by reducing external component count.
• AEC-Q101 qualified for reliability in automotive electronic environments.
• High-frequency operation capability up to 250 MHz supports fast switching applications.

Applications

• Automotive logic interface circuits
• General-purpose switching applications
• Driver circuits for low-power loads

Procurement Notes

Verify the specific suffix HE3-TP against the manufacturer's latest datasheet to confirm lead-free status and RoHS compliance. Confirm that the SOT-23 package dimensions match the PCB footprint requirements. Ensure the -50 V rating aligns with the target circuit's voltage levels. Check for any regional distribution restrictions or supply limitations before finalizing procurement plans.

Selection Notes

Select this component when a PNP digital transistor with integrated biasing is required for space-constrained designs. The 10 kOhm base resistor value suits standard logic level interfacing. Consider the 200 mW power dissipation limit for thermal management. Verify that the -100 mA current capacity meets the load requirements. Compare with the NPN counterpart DTC114ECAHE3-TP if polarity differs.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from MCC. It serves as the PNP equivalent to the DTC114 series. The HE3 designation typically indicates environmental compliance features. The TP suffix denotes tape and reel packaging availability. This family is designed to replace discrete resistor-transistor combinations in compact electronics.

Replacement Considerations

Direct substitutes include other PNP digital transistors with similar -50V ratings and SOT-23 packages. Verify pinout compatibility and electrical parameters such as hFE and R1 values. Cross-reference with DTA114YCAHE3-TP for potential pin-compatible alternatives within the same manufacturer line.
