2SA1682-4-TB-E

Single Bipolar Transistors Overview

The onsemi 2SA1682-4-TB-E is a PNP bipolar junction transistor (BJT) designed for high-voltage switching applications. It features a collector-emitter breakdown voltage of 300V and a continuous collector current rating of 50mA. The device is housed in a compact SOT-23VAR surface-mount package, facilitating automated assembly and space-constrained designs. Key electrical characteristics include a typical reverse transfer capacitance of 1.5pF, which supports excellent high-frequency performance. This component serves as a direct replacement for the original Sanyo Semicon Device part number 2SA1682-4, maintaining identical pinout and functional specifications within the onsemi portfolio.

Single Bipolar Transistors Feature Summary

• High breakdown voltage capability exceeding 300V for robust operation in demanding circuits
• Optimized high-frequency characteristics with low reverse transfer capacitance
• Compact SOT-23VAR surface-mount package design for efficient board space utilization

Single Bipolar Transistors Applications

• Audio line driver stages requiring low output capacitance
• GPIO protection and signal conditioning interfaces

Single Bipolar Transistors Procurement Notes

Verify that the specific suffix -TB-E corresponds to the required tape-and-reel packaging configuration if automated placement is intended. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the sourcing channel provides valid traceability for the onsemi brand designation. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing specifications and material composition declarations.

Single Bipolar Transistors Selection Notes

Select this component when circuit requirements demand a PNP transistor capable of handling 300V collector-emitter voltage with moderate 50mA current capacity. The low capacitance profile makes it suitable for applications where signal integrity at higher frequencies is critical. Consider the SOT-23VAR footprint constraints during layout planning. This device is appropriate for replacing legacy Sanyo parts in existing designs without modifying the PCB layout or schematic topology.

Single Bipolar Transistors Part Context

This component belongs to the single bipolar transistor category within the onsemi product lineup. It represents the continuation of the 2SA1682 series originally developed by Sanyo Semicon Device. The -4 variant specifically denotes the SOT-23VAR package style. The product maintains the electrical performance standards established by the predecessor while adhering to modern manufacturing quality and reliability frameworks provided by onsemi.

Single Bipolar Transistors Replacement Considerations

The 2SA1682-4-TB-E is the direct onsemi equivalent for the Sanyo 2SA1682-4. Designers transitioning from the original Sanyo part should verify that the -TB-E suffix meets specific packaging requirements. Electrical parameters remain consistent, allowing for drop-in replacement in validated designs without requalification of the core circuit functionality.
