Overview
The DDTB142TC-7 is a PNP pre-biased digital transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction and integrates biasing resistors R1 (0.47 kΩ) and R2 (10 kΩ). The device operates with a maximum collector current of -500 mA and a supply voltage of -50 V. Electrical characteristics include a DC current gain (hFE) ranging from 100 to 600 at IC = -5mA, and a gain-bandwidth product of 200 MHz. The component is housed in a SOT-23 surface-mount package and supports an operating temperature range from -55°C to +150°C.
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
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic level translation interfaces
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 representatives. Standard procurement channels may not support new orders. Engineering teams should initiate replacement strategies immediately to ensure long-term supply stability for production schedules.
Selection Notes
Select this part only if legacy compatibility is required. Verify that the integrated resistor values (R1=0.47kΩ, R2=10kΩ) match the specific drive requirements. Ensure the SOT-23 footprint aligns with existing PCB layouts. Confirm thermal management capabilities within the specified ambient temperature range during system design validation.
Part Context
The DDTB142TC-7 belongs to the DDTB series of PNP pre-biased transistors. It serves as the complementary counterpart to NPN types within the DDTD family. This specific variant distinguishes itself through its 0.47 kΩ input resistor configuration, differentiating it from other series members like the DDTB122TC or DDTB142JC.
