Overview
The DDTA115GCA-7-F is a PNP pre-biased small signal transistor from the DDTA (R2-only series) CA by Diodes Incorporated. It features an integrated 100 kOhm biasing resistor (R2) within a surface-mount SOT-23 package. Key electrical ratings include a collector-emitter voltage of -50 V, continuous collector current of -100 mA, and power dissipation of 200 mW at 25°C. The device operates across a temperature range of -55°C to +150°C with a gain-bandwidth product of 250 MHz.
Feature Summary
- Integrates a single built-in biasing resistor (R2 only) for simplified circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Qualified to AEC-Q101 standards for high reliability applications
Applications
- Switching circuits requiring integrated base biasing
- Driver stages for low-power loads
- General-purpose digital logic interfacing
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and green molding compound status via date codes. Ensure storage conditions adhere to moisture sensitivity level 1 requirements. Validate ordering suffixes against official manufacturer documentation prior to procurement.
Selection Notes
Select this component when a PNP configuration with a fixed 100 kOhm internal resistor is required. Compare against complementary NPN types in the DDTC series if polarity reversal is needed. Verify thermal resistance and power dissipation limits relative to the specific PCB layout and ambient operating conditions.
Part Context
This part belongs to the DDTA115 family of pre-biased transistors. Variants such as DDTA114GCA, DDTA124GCA, and DDTA144GCA share identical physical dimensions and electrical characteristics except for the nominal value of the integrated R2 resistor, which ranges from 10 kOhms to 47 kOhms.
Replacement Considerations
Direct substitutes include other DDTA115 variants with different packaging or suffixes. Complementary NPN equivalents are available in the DDTC115 series. Cross-reference pinouts and resistor tolerances when replacing with generic discrete components.
