Overview
The DDTA123YUA-7 is a PNP pre-biased small signal surface mount transistor manufactured by Diodes Incorporated. It features an epitaxial planar die construction in a SOT-323 case. The device integrates internal biasing resistors with nominal values of R1 = 2.2 kΩ and R2 = 10 kΩ. Key electrical ratings include a supply voltage (VCC) of -50 V, a continuous collector current (IC) of -100 mA, and power dissipation (Pd) of 200 mW at 25°C ambient temperature. The transition frequency (fT) is typically 250 MHz. Operating and storage temperatures range from -55°C to +150°C.
Feature Summary
- Integrates built-in biasing resistors with unequal resistance values for simplified circuit design.
- Utilizes epitaxial planar die construction for reliable performance.
- Available in a compact SOT-323 surface mount package.
Applications
- General-purpose switching applications
- Driver circuits requiring integrated biasing
- Logic interface circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details. The datasheet lists the -7-F variant as being supplied in tape and reel quantities of 3000 units. Confirm that the component meets RoHS compliance requirements if necessary for the intended application environment.
Selection Notes
Select this component when a PNP digital transistor with a 2.2 kΩ base resistor and 10 kΩ emitter resistor is required. Ensure the design accommodates the -50 V maximum supply voltage and -100 mA output current limits. Consider the thermal resistance of 625 °C/W for heat dissipation calculations in the SOT-323 package.
Part Context
This component belongs to the DDTA1x3 series of PNP pre-biased transistors from Diodes Incorporated. It serves as the complement to the DDTC1x3 NPN series. The 'Y' designation specifically identifies the resistor ratio configuration within the family, distinguishing it from variants like the JUA or ZUA which have different resistance values.
Replacement Considerations
Direct substitutes include the DDTA123YUA-7-F. Cross-manufacturer equivalents such as the PDTA123YU,115 from Nexperia or DTB123YUT106 from Rohm Semiconductor are listed as similar alternatives.
