Overview
The DDTA144TE-7-F is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT523 package. It features a built-in bias resistor (R1) with a nominal value of 47 kOhms. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of 100 mA. Power dissipation is rated at 150 mW, with an operating temperature range from -55°C to +150°C. The DC current gain (hFE) has a minimum value of 100, and the transition frequency is typically 250 MHz.
Feature Summary
- Integrates a single internal bias resistor for simplified circuit design
- Utilizes epitaxial planar die construction for reliability
- Compliant with RoHS standards and free of halogen and antimony
Applications
- General-purpose switching applications
- Driver circuits for logic interfaces
- Pre-biasing stages in analog signal processing
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the marking code matches 'P19' for the DDTA144TE-7-F variant. Ensure packaging specifications align with reel quantities of 3000 units per 7-inch tape width. Check for compliance with RoHS 3 directives before final procurement decisions.
Selection Notes
Select this component when a PNP digital transistor with a 47 kOhm base resistor is required. The SOT523 package offers a compact footprint suitable for space-constrained designs. Consider the 150 mW power dissipation limit and -50 V voltage rating during thermal and electrical stress analysis. Verify compatibility with the intended logic levels and switching speeds.
Part Context
This part belongs to the DDTA R1-only series, which integrates only the base bias resistor. Complementary NPN types are available within the DDTC series. The product line includes various resistor values ranging from 1 kOhm to 200 kOhm, allowing for flexible design options across different input impedance requirements.
Replacement Considerations
Direct substitutes include other DDTA144 variants such as DDTA144TCA-7-F or DDTA144VCA-7-F, provided the package type (SOT-23-3 vs SOT523) and pinout compatibility are verified. Ensure any replacement maintains the same 47 kOhm resistor value and PNP polarity.
