Overview
The DDTA142JE-7-F is a PNP pre-biased surface mount transistor manufactured by Diodes Incorporated. It features built-in biasing resistors with nominal values of R1 = 0.47 kΩ and R2 = 10 kΩ, housed in an SOT-523 package. The device supports a maximum collector-emitter voltage (BVCEO) of -40 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 component includes a gain-bandwidth product of approximately 200 MHz and meets RoHS compliance standards.
Feature Summary
- Integrates built-in biasing resistors to simplify circuit design and reduce board space.
- Utilizes epitaxial planar die construction for reliable performance.
- Offers complementary NPN types within the same series for flexible configuration.
Applications
- General-purpose switching applications requiring compact form factors.
- Driver circuits for low-power loads where external biasing components are undesirable.
- Logic interface circuits utilizing standard voltage levels.
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. Ensure that the requested variant matches the required resistor ratios and marking codes. Confirm compliance requirements such as RoHS status prior to procurement. Cross-reference the manufacturer part number with distributor listings to ensure authenticity. Review datasheet notes regarding moisture sensitivity and handling precautions.
Selection Notes
Select this component when a PNP pre-biased transistor with specific internal resistance values is required. The SOT-523 package is suitable for space-constrained designs. Consider the thermal resistance and power derating curves for high-temperature environments. Verify that the input voltage limits align with the system logic levels. Compare electrical characteristics against alternative devices if higher current or voltage ratings are needed.
Part Context
This component belongs to the DDTA series of pre-biased transistors from Diodes Incorporated. The series offers various combinations of internal resistors and packages to suit different application needs. The DDTA142JE-7-F specifically provides a PNP configuration with defined biasing ratios. It is designed for use in consumer electronics and industrial control systems requiring efficient signal switching.
Replacement Considerations
Complementary NPN types such as DDTC142 are available within the same series. Other variants in the DDTA family offer different resistor ratios or package options. Verify pinout compatibility and electrical specifications before substituting. Consult the manufacturer's documentation for approved alternatives.
