Overview
The DDTA124GKA-7-F is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SC-59 package. It features an epitaxial planar die construction with a built-in biasing resistor (R2 only) of 22 kOhms nominal value. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous collector current of -100 mA, with a power dissipation rating of 200 mW. Operating temperature ranges from -55°C to +150°C. DC current gain (hFE) has a minimum value of 56 at IC = -5mA, VCE = -5V.
Feature Summary
- Epitaxial planar die construction for reliable performance
- Integrated single biasing resistor simplifies circuit design
- Lead-free plating with matte tin finish over copper leadframe
- RoHS compliant and available in green molding compound
Applications
- General-purpose switching applications
- Driver circuits for low-power loads
- Logic interface buffering
Procurement Notes
Verify the specific ordering suffix '-7-F' against official Diodes Incorporated documentation to confirm tape and reel packaging quantities and RoHS compliance status. Ensure the SC-59 footprint matches the target PCB layout dimensions provided in the mechanical data section of the datasheet before finalizing procurement orders.
Selection Notes
Select this component when a PNP digital transistor with a 22k Ohm internal pull-up resistor is required. Compare hFE minimums and VCEO ratings against load requirements. Verify that the SC-59 package size fits within the available board space constraints compared to alternatives like SOT-23 or SOT-323.
Part Context
This part belongs to the DDTA R2-only series, which integrates a single biasing resistor into the transistor package. It serves as a complementary counterpart to the DDTC NPN series. The 'KA' designation specifically indicates the SC-59 case style and the 22k Ohm resistor value variant within the broader DDTA family.
Replacement Considerations
Direct pin-compatible replacements include other DDTA124 variants in SC-59 packages such as DDTA124EKA-7 or DDTA124TCA-7-F, provided their electrical characteristics meet the application requirements.
