Single Bipolar Transistors Procurement Notes

Verify the specific suffix 'AA' against the manufacturer's official documentation to confirm pinout and mechanical dimensions, as suffixes often denote specific tape-and-reel or packaging variations. Ensure the sourcing channel provides original Sanyo or authorized distributor evidence. Cross-reference the datasheet revision date to guarantee compatibility with current manufacturing standards. Confirm that the received components match the specified flange mount package type and terminal configuration.

Single Bipolar Transistors Selection Notes

Select this component when a high-voltage NPN switching transistor with a 500V rating and 4A continuous current capacity is required. The flange mount package facilitates direct heatsinking for thermal management in high-power scenarios. Consider the minimum hFE of 15 for base drive circuit calculations. This part is suitable for designs prioritizing high reliability and isolation between the case and internal circuitry.

Single Bipolar Transistors Part Context

The 2SC4455 series belongs to Sanyo's lineup of power bipolar transistors. These devices are engineered for general-purpose use in consumer and industrial electronics. The Q-AA variant specifies the particular packaging and handling format within the broader 2SC4455 family. Sanyo Semicon Device was a recognized manufacturer before its acquisition, contributing to the component's established history in the market.

Single Bipolar Transistors Replacement Considerations

Direct substitutes must match the 500V V(BR)CEO, 4A IC, NPN polarity, and flange mount package. Verify equivalent hFE characteristics and thermal resistance values. Check for compatible mounting hole patterns and terminal arrangements to ensure mechanical interchangeability without PCB redesign.
