2SD1835S

Single Bipolar Transistors Overview

The onsemi 2SD1835S is an NPN single bipolar transistor housed in the NP package, equivalent to SC-34A, TO-92, or SOT-54. It features a collector-to-emitter voltage of 50V and a continuous collector current of 2A. The device utilizes FBET and MBIT processes for large current capacity and fast switching times. Key electrical characteristics include a DC current gain (hFE) ranging from 100 to 560 at 100mA, a gain-bandwidth product of 150MHz, and a low collector-to-emitter saturation voltage of 0.4V maximum at 1A.

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging format. The 'S' suffix indicates bag packing, while 'AA' denotes box taping. Confirm that the required hFE rank aligns with the application needs, as gain varies significantly across ranks. Ensure the NP package dimensions match the target PCB layout constraints before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when designing circuits requiring high-speed switching and robust current handling within a compact form factor. The wide hFE range necessitates checking the specific rank for biasing stability. Consider the thermal dissipation limits, as power ratings decrease with rising ambient temperatures. Verify that the 50V breakdown voltage exceeds the peak operating voltages in the intended circuit environment.

Single Bipolar Transistors Part Context

This part belongs to the 2SD1835 series of NPN bipolar transistors manufactured by onsemi. The series includes variants such as 2SD1835T and 2SD1835S-AA, which share identical electrical specifications but differ in shipping packaging. These devices are designed for general-purpose switching applications where low saturation voltage and fast response are critical requirements.

Single Bipolar Transistors Replacement Considerations

Direct substitutes include 2SD1835T and 2SD1835S-AA, which maintain identical electrical parameters. Cross-referencing with other NPN transistors requires verifying pinout compatibility and ensuring comparable VCEO, IC, and switching speed specifications.
