DDTB142JC-7-F

Overview

The DDTB142JC-7-F is a PNP pre-biased transistor manufactured by Diodes Incorporated, housed in an SOT-23 package. It features built-in biasing resistors with nominal values of R1 = 0.47 kΩ and R2 = 10 kΩ. The device supports a maximum collector current of 500 mA and a collector-emitter breakdown voltage (BVCEO) of -40 V. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C. The minimum DC current gain (hFE) is specified as 56.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Totally lead-free and fully RoHS compliant
• Halogen and antimony free "Green" device

Applications

• Automotive applications requiring specific change control
• General-purpose switching circuits
• Driver circuits for low-power loads

Procurement Notes

This component is officially marked as obsolete and discontinued by the manufacturer. Verification of availability should focus on remaining stock or alternative sourcing channels rather than direct procurement from Diodes Incorporated. Confirm end-of-life status before finalizing designs.

Selection Notes

Select this part only if legacy compatibility is required due to its discontinued status. Verify that the 0.47 kΩ base resistor and 10 kΩ emitter resistor values align with the target circuit requirements. Ensure the -40 V voltage rating meets system constraints.

Part Context

The DDTB142JC-7-F belongs to the DDTB series of PNP pre-biased transistors. It is complementary to NPN types within the same family. The suffix 'JC' indicates the specific resistor ratio configuration. This series is designed for surface-mount applications using the SOT-23 case.

Replacement Considerations

Check for available DDTB142TC-7-F if different resistor values are acceptable. Verify if other PNP pre-biased transistors from the DDTB series meet the electrical specifications.
