Overview
The DDTA124EE-7-F is a PNP pre-biased transistor from Diodes Incorporated, housed in an SOT523 surface-mount package. It integrates two equal biasing resistors (R1 = R2) with a nominal value of 22 kΩ. The device supports a maximum supply voltage of 50 V and a continuous collector current of -100 mA. Electrical characteristics include a typical input low voltage of -1.1 V and a DC current gain minimum of -56 at -5 V and -5 mA. Thermal performance specifies a power dissipation of 150 mW and a junction-to-ambient thermal resistance of 833 °C/W. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Epitaxial planar die construction for high reliability
- Integrated equal-value biasing resistors simplify circuit design
- Totally lead-free and fully RoHS compliant
- Halogen and antimony-free green device
Applications
- General-purpose switching applications
- Driver circuits for logic interfaces
- Automotive electronics requiring specific change control
Procurement Notes
Verify the component against the official datasheet DS30317 Rev. 10-2 to confirm authenticity. Ensure the marking code matches 'P17' for the DDTA124EE series. Check that the packaging quantity aligns with the standard 3,000-unit reel specification. Confirm compliance with RoHS 3 and REACH regulations as stated by the manufacturer.
Selection Notes
Select this part when a PNP configuration with integrated 22 kΩ biasing resistors is required. The SOT523 package is suitable for space-constrained designs. Verify that the -100 mA output current and 50 V voltage ratings meet the application requirements. Consider the complementary NPN type if an equivalent NPN solution is needed.
Part Context
This component belongs to the DDTA (R1 = R2 Series) EE family of pre-biased transistors. It is designed for high-reliability applications and is qualified to JEDEC standards. The product line includes various resistor values ranging from 2.2 kΩ to 100 kΩ, all sharing the same epitaxial planar construction and SOT523 packaging format.
Replacement Considerations
The complementary NPN version DDTC124EE-7-F offers identical electrical characteristics and pinout for NPN applications. Other members of the DDTA124EE series share the same resistor values but may differ in marking codes or packaging suffixes.
