Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official Toshiba documentation to confirm environmental compliance status, such as RoHS compatibility, as indicated by lot number markings. Ensure the selected variant matches the required DC current gain classification (O or Y) for your circuit design. Confirm availability through authorized distributors, as manufacturing status may change without notice.

Single Bipolar Transistors Selection Notes

Select this component for designs requiring a PNP counterpart to the 2SC3668. Evaluate the hFE classification requirements; the 'Y' suffix indicates a higher gain range (120-240) compared to the standard 'O' classification. Consider the thermal derating curves provided in the datasheet when designing for ambient temperatures exceeding 25°C to maintain safe operating area limits.

Single Bipolar Transistors Part Context

This component belongs to the Toshiba 2SA series of general-purpose bipolar junction transistors. It utilizes an epitaxial planar structure designed for robust performance in consumer electronics and industrial equipment. The device is intended for use in computers, office equipment, and measuring instruments, adhering to standard reliability guidelines for general electronic applications.

Single Bipolar Transistors Replacement Considerations

The 2SA1428 is electrically complementary to the 2SC3668 NPN transistor. When replacing, ensure the substitute part matches the -50 V collector-emitter voltage rating and -2 A continuous collector current limit. Verify that the replacement package type accommodates the physical footprint constraints of the original design.
