Overview
The PDTA123YM,315 is a digital transistor manufactured by Nexperia USA Inc., featuring an integrated NPN bipolar junction transistor with built-in biasing resistors. It is housed in the SOT-883B (DFN1006-3) surface-mount package, measuring 1.02 mm in length, 0.62 mm in width, and 0.47 mm in height. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Typical internal resistor values include a base resistor of 2.2 kOhms and an emitter resistor of 10 kOhms, yielding a typical resistor ratio of 0.222. It operates within a temperature range of -65°C to +150°C.
Feature Summary
- Integrates an NPN transistor with dual biasing resistors to simplify circuit design and reduce component count.
- Utilizes a compact DFN1006-3 footprint for efficient space utilization on high-density printed circuit boards.
- Engineered for high-temperature operation, supporting ambient temperatures up to 150°C.
Applications
- General-purpose switching applications in consumer electronics.
- Level shifting and logic interface circuits.
- Driver stages for low-current loads in embedded systems.
Procurement Notes
Verify the specific suffix '315' corresponds to the required tape-and-reel packaging configuration from official Nexperia documentation. Confirm that the SOT-883B package variant matches the PCB footprint requirements. Ensure compliance with RoHS directives as indicated in manufacturer specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN digital transistor with a 50V rating and 100mA current capacity is required. The fixed 2.2k/10k resistor network suits standard logic interfacing. Consider the DFN1006-3 thermal and mechanical constraints compared to larger packages like SOT-23 if higher power dissipation or ease of assembly is prioritized.
Part Context
This part belongs to the PDTC123 series of pre-biased transistors from Nexperia. It serves as a direct replacement for legacy parts such as the PDTC123YM315 previously listed under NXP branding. The component is designed to replace discrete resistor-transistor combinations, offering improved consistency and reduced board space in modern electronic designs.
Replacement Considerations
The PDTA123YM,315 is functionally similar to the PDTA123JMB,315. Verify pinout compatibility and exact resistor tolerances against the original design specifications before substitution.
