Overview
The DDTA142JE-7-F is a PNP pre-biased surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT-523 package. The device integrates built-in biasing resistors with nominal values of R1 = 0.47 kΩ and R2 = 10 kΩ. Key electrical ratings include a maximum collector-emitter voltage (BVCEO) of -40 V, a continuous collector current of -100 mA, and a power dissipation of 150 mW at 25°C ambient temperature. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Integrates built-in biasing resistors for simplified circuit design
- Utilizes epitaxial planar die construction for reliability
- Available in compact SOT-523 surface mount package
Applications
- General-purpose switching applications
- Driver circuits for low-current loads
- Logic interface level shifting
Procurement Notes
Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. Confirm RoHS compliance status through official datasheets or product compliance reports before integration into regulated assemblies. Ensure storage conditions adhere to moisture sensitivity level requirements specified in the mechanical data section.
Selection Notes
Select this component when a PNP configuration with integrated base and emitter resistors is required. The 0.47 kΩ input resistor value suits applications needing moderate drive currents. Verify that the -40 V collector-emitter breakdown voltage meets the system's maximum operating voltage constraints. Consider the SOT-523 footprint dimensions during PCB layout planning.
Part Context
This part belongs to the DDTA series of pre-biased transistors from Diodes Incorporated. It serves as the PNP counterpart to the DDTC NPN series. The 'JE' designation specifically identifies the resistor ratio combination of 0.47 kΩ and 10 kΩ within the SOT-523 form factor.
Replacement Considerations
Direct functional substitutes within the same family include the DDTA142TE-7-F, which shares the same package but lacks the second biasing resistor (R2). Cross-family replacements require matching polarity, voltage ratings, and current capabilities.
