DTA114ECAHZGT116

Overview

DTA114ECAHZGT116 is a single PNP digital transistor manufactured by ROHM Semiconductor, housed in an SST3 (SOT-23) surface-mount package. It features built-in bias resistors with values of 10 kOhms for both R1 and R2, resulting in a resistance ratio of 1. The device supports a maximum collector current of 100 mA and a collector-emitter voltage of -50 V. Key electrical parameters include a minimum DC current gain (hFE) of 30 at -5 mA and -5 V, a transition frequency of 250 MHz, and a power dissipation rating of 350 mW. It is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Integrates thin-film bias resistors to enable inverter circuit configuration without external input components.
• Provides complete isolation between bias resistors to allow negative input biasing.
• Eliminates parasitic effects associated with discrete resistor networks.
• Simplifies circuit design by requiring only on/off condition settings.

Applications

• Inverter circuits
• Interface logic
• Driver circuits

Procurement Notes

Verify the specific suffix GT116 against the official ROHM datasheet to confirm packaging details such as reel size or tape width. Ensure the component meets AEC-Q101 automotive grade requirements if used in vehicle electronics. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm active status and RoHS compliance before finalizing procurement orders.

Selection Notes

Select this component when a PNP digital transistor with equal 10 kOhm bias resistors is required. It is suitable for applications needing a 250 MHz transition frequency and 100 mA continuous collector current. Consider the SOT-23 footprint for space-constrained designs. Verify that the -50 V collector-emitter voltage rating aligns with the system's supply voltage constraints.

Part Context

This part belongs to the DTA114 series of pre-biased transistors from ROHM Semiconductor. It serves as the PNP counterpart to the NPN DTC114ECAHZGT116. The series is designed for high reliability in automotive environments, adhering to AEC-Q101 standards. The SST3 package provides a compact solution for surface-mount assembly processes.

Replacement Considerations

The complementary NPN equivalent is DTC114ECAHZGT116. Other variants in the DTA114 family may offer different resistance ratios or voltage ratings. Verify pinout compatibility and thermal characteristics when substituting with other SOT-23 digital transistors from different manufacturers.
