Overview
The DDTB142TC-7-F is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-23 package. It integrates biasing resistors with a nominal R1 of 0.47kΩ and R2 of 10kΩ. The device supports a maximum collector current of -500 mA and a supply voltage of -50 V. Electrical characteristics include a minimum DC current gain (hFE) of 100 at -5mA and a typical gain-bandwidth product of 200 MHz. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Integrates built-in biasing resistors for simplified circuit design
- Utilizes epitaxial planar die construction for reliability
- Complies with RoHS standards and is halogen-free
Applications
- General-purpose switching applications
- Driver circuits requiring integrated biasing
- Automotive electronics (subject to specific qualification requirements)
Procurement Notes
This component is officially marked as obsolete and discontinued by the manufacturer. Verification of availability requires direct contact with Diodes Incorporated or authorized distributors, as standard commercial channels may not stock this part. Engineering teams should initiate replacement strategies immediately due to the confirmed end-of-life status.
Selection Notes
Select this component only if legacy compatibility is mandatory. For new designs, consider alternative PNP digital transistors within the same series that offer active manufacturing status. Verify that the 0.47kΩ input resistor and 10kΩ output resistor values align precisely with the target circuit's drive requirements.
Part Context
The DDTB142TC-7-F belongs to the DDTB series of PNP pre-biased transistors. It serves as the complement to the NPN DDTD series. This specific variant features a 0.47kΩ base resistor and a 10kΩ emitter resistor configuration, designed for high-speed switching tasks in compact surface-mount layouts.
Replacement Considerations
Direct substitutes include other DDTB series parts with identical resistor ratios but different packaging, such as DDTB142JC-7-F. Engineers must verify pinout compatibility and thermal performance when transitioning between SOT-23 variants.
