The DDTA125TCA-7 is a PNP pre-biased transistor from the DDTA (R1-ONLY SERIES) CA family, manufactured by Diodes Incorporated. It features an epitaxial planar die construction housed in a SOT23 package. The device integrates a single built-in biasing resistor with a nominal value of 200 kΩ. Key electrical specifications include a collector-emitter voltage (VCEO) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (PD) of 200 mW at +25°C. The DC current transfer ratio (hFE) ranges from 100 to 600 under standard test conditions.
Verify component status before procurement as this specific part number is listed as obsolete in official documentation. Confirm availability of active replacements such as the DDTA125TCA-7-F variant if continued production is required. Ensure sourcing channels are authorized to guarantee authenticity and compliance with environmental directives.
Select this component when a PNP configuration with a 200 kΩ base resistor is needed within a compact SOT23 footprint. Consider the -50 V breakdown voltage and -100 mA current limits against application requirements. Evaluate thermal resistance characteristics for high-temperature environments exceeding standard operating ranges.
This component belongs to the DDTA R1-Only Series CA, which provides PNP pre-biased transistors with varying resistor values. The 'CA' suffix indicates the specific pinout and marking code associated with the SOT23 package. Complementary NPN types are available in the DDTC series for designs requiring matched pairs or differential configurations.
The DDTA125TCA-7-F is documented as an active alternative within the same series. Verify pin compatibility and electrical parameter equivalence before substitution. Check for updated packaging or marking codes that may differ from the obsolete version.
