What are the key features of PDTA123JU?
- Integrated 2.2 kΩ input resistor and 47 kΩ bias resistor (ratio 0.047) eliminate external discrete resistors, reducing BOM count by 2 components per stage
- PNP configuration rated at 100 mA collector current and 50 V VCEO supports logic-level switch driving of LEDs, relays, and small loads directly from MCU output pins
- Compact SOT323 (UMT) 3-pin SMD package minimizes PCB area to under 1 mm² per transistor in dense handheld and wearable designs
What is PDTA123JU used for?
The PDTA123JU is used in smartphones, wearables, and IoT sensor nodes to switch LEDs, buzzers, and low-current loads from 3.3 V or 5 V MCU GPIO pins without separate bias resistors. Its built-in 2.2 kΩ and 47 kΩ resistor network makes it a drop-in single-component solution for PNP switch stages in consumer electronics where board space and component count are tightly constrained.

Frequently Asked Questions
What built-in resistors does the PDTA123JU include, and how do they simplify circuit design?
The PDTA123JU integrates a 2.2 kΩ base input resistor and a 47 kΩ base-to-emitter bias resistor in a single SOT323 package, giving a bias ratio of 0.047. This eliminates two discrete SMD resistors per transistor stage, saving PCB area and reducing pick-and-place operations in high-volume consumer and IoT PCB assembly lines.
What is the maximum collector current and collector-emitter voltage of the PDTA123JU, and what loads can it switch?
The PDTA123JU is rated for 100 mA maximum collector current and 50 V collector-emitter voltage. These ratings allow it to directly switch indicator LEDs drawing up to 20 mA, small signal relays with coils up to 50 mA, and piezo buzzers from a 3.3 V or 5 V logic supply, all with a minimum DC current gain (hFE) of 100 for reliable saturation switching.
When is the PDTA123JU a lower-component-count alternative to a discrete PNP transistor plus external resistors?
Any PNP switch stage using a standard transistor like BC857 requires at least 2 external resistors (a base series resistor and a pull-down to prevent false turn-on) that the PDTA123JU replaces with a single 3-pin UMT package. On a board with 50 such switch stages, substituting PDTA123JU saves 100 passive components and the associated 100 solder joints, improving assembly yield in portable devices with dense 0402-scale layouts.
