Overview
The DTA144TU3HZGT106 is a PNP digital transistor manufactured by ROHM Semiconductor, featuring a built-in bias resistor (R1) in an SOT-323 (UMT3) surface-mount package. It operates with a collector-emitter voltage of -50 V and a continuous collector current of -100 mA. The device includes a typical input resistance of 47 kOhms and achieves a minimum DC current gain (hFE) of 100 at 1 mA and 5 V. It supports a maximum operating frequency of 250 MHz and dissipates up to 200 mW of power. Designed for automotive applications, it complies with AEC-Q101 standards and functions within a temperature range of -55°C to +150°C.
Feature Summary
- Integrates a single bias resistor to simplify circuit design by eliminating external input components.
- Complies with AEC-Q101 automotive grade standards for enhanced reliability in vehicle electronics.
- Utilizes a compact SOT-323 package suitable for space-constrained surface-mount applications.
Applications
- Inverter circuits
- Interface drivers
- Automotive electronic control units
Procurement Notes
Verify the specific suffix GT106 against official ROHM documentation to confirm reel quantity and tape specifications. Ensure compatibility with AEC-Q101 requirements if used in automotive designs. Cross-reference the ordering code with authorized distributors to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a PNP digital transistor with a 47 kOhm base resistor is required for automotive or high-reliability applications. The SOT-323 package offers a small footprint compared to larger alternatives. Verify that the -50 V rating and -100 mA current capacity meet the specific load requirements of the target circuit design.
Part Context
This part belongs to the DTA144TU3HZ series of PNP digital transistors designed for automotive use. It shares the same pinout and core electrical characteristics as other variants in the family but differs in packaging and taping specifications. The 'TU3' designation indicates the SOT-323 form factor, while 'HZ' denotes automotive qualification.
Replacement Considerations
DTA143TU3HZGT106: Offers identical pinout and package but features a 4.7 kOhm input resistor instead of 47 kOhm. Verify resistor value compatibility before substitution.
