Overview
The DDTC124GCA-7-F is an NPN pre-biased small signal transistor from Diodes Incorporated, housed in a SOT-23 surface-mount package. It features a built-in biasing resistor R2 with a nominal value of 22 kOhms. The device supports a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C. The component utilizes epitaxial planar die construction and includes lead-free plating.
Feature Summary
- Integrates a single internal biasing resistor (R2 only) to simplify circuit design
- Constructed using epitaxial planar die technology for reliable performance
- Manufactured as a lead, halogen, and antimony-free RoHS compliant green device
Applications
- General-purpose switching applications requiring simplified base drive circuits
- Driver stages for logic interfaces where external biasing components are minimized
- Low-power signal processing circuits within the specified voltage and current limits
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details and shipping quantities. Ensure that the requested part number matches the exact electrical characteristics and marking codes defined in the datasheet. Confirm compliance requirements such as RoHS status and material composition directly with the supplier or manufacturer before finalizing procurement orders.
Selection Notes
Select this component when a single NPN pre-biased transistor with a 22 kOhm emitter resistor is required in a compact SOT-23 footprint. Consider the 200 mW power dissipation limit and 50 V voltage rating during thermal and electrical design. Verify that the 250 MHz gain-bandwidth product meets the frequency requirements of the intended application.
Part Context
This component belongs to the DDTC (R2-ONLY SERIES) CA family produced by Diodes Incorporated. The series offers complementary PNP types under the DDTA designation. The 'GCA' suffix indicates the specific pinout and physical dimensions associated with the SOT-23 case style used in this product line.
Replacement Considerations
Direct replacements within the same series include DDTC114GCA-7-F, DDTC144GCA-7-F, and DDTC115GCA-7-F, which share identical mechanical and electrical specifications but differ in the nominal value of the internal R2 resistor.
