DTA114YU3HZGT106

Overview

The DTA114YU3HZGT106 is a single NPN digital transistor manufactured by ROHM Semiconductor, housed in an SOT-323-3 surface-mount package. It features a built-in bias resistor network with typical values of R1 at 10 kOhms and R2 at 47 kOhms (ratio 4.7). The device supports a supply voltage of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a minimum DC current gain (hFE) of 68 at -5 mA/-5 V, a maximum operating frequency of 250 MHz, and power dissipation of 200 mW. It operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates bias resistors to simplify circuit design by eliminating external input components for inverter configurations.
• Meets AEC-Q101 standards for high reliability in automotive electronic applications.
• Provides stable switching performance with a high DC current gain suitable for low-current drive scenarios.

Applications

• Automotive interface circuits requiring robust signal switching.
• Inverter circuits where external base resistors are omitted.
• Driver stages for low-power loads in vehicle electronics.

Procurement Notes

Verify the specific suffix HZGT106 against the manufacturer's latest datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering part number matches the required reel quantity of 3000 units. Cross-reference the AEC-Q101 qualification documentation if automotive grade certification is strictly required for the final assembly.

Selection Notes

Select this component when an NPN digital transistor with a 10k input resistor and 47k emitter-base resistor is needed in a compact SOT-323 footprint. It is appropriate for designs requiring AEC-Q101 compliance and operation up to 150°C. Compare hFE specifications against load requirements to ensure sufficient gain at the target operating current.
