Overview
The DDTA114GUA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-323 package. It features an epitaxial planar die construction with a built-in biasing resistor R2 of 10 kΩ nominal value. Key electrical parameters 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. The device exhibits a DC current transfer ratio (hFE) minimum of 30 at IC = -5 mA and VCE = -5 V, with a gain-bandwidth product (fT) of 250 MHz. Operating temperature range spans from -55°C to +150°C.
Feature Summary
- Integrates a single internal emitter resistor (R2) for simplified circuit design
- Utilizes epitaxial planar die construction for reliable performance
- Offers RoHS compliance and lead-free plating options
Applications
- Switching applications requiring integrated base biasing
- Driver circuits for low-power loads
- General-purpose digital logic interfacing
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging quantity and tape-and-reel specifications. Ensure that any requested variants match the exact part number structure, as suffixes may indicate differences in shipping configuration rather than electrical function. Cross-reference the manufacturer's latest datasheet revision to confirm current availability status and manufacturing date code requirements.
Selection Notes
Select this component when a PNP transistor with a fixed emitter resistor is required to simplify biasing networks. The SOT-323 package is suitable for space-constrained surface-mount designs. Consider the 10 kΩ nominal R2 value and the -50 V voltage rating to ensure compatibility with the target circuit's operating conditions and load requirements.
Part Context
This component belongs to the DDTA series of pre-biased transistors manufactured by Diodes Incorporated. The 'UA' designation indicates the SOT-323 case style and the inclusion of only the R2 resistor. The 'G' suffix typically denotes the specific resistor value within the series, while '-7-F' specifies the tape-and-reel packaging format.
Replacement Considerations
Complementary NPN types such as DDTC are available from the same manufacturer. Verify pinout compatibility and electrical parameter alignment before substitution.
