Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to ensure exact pinout and thermal characteristics match design requirements. Confirm RoHS compliance status if environmental regulations apply to the end product. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability. Ensure the TO-220ML package dimensions align with PCB footprint constraints before finalizing procurement decisions.

Single Bipolar Transistors Selection Notes

Select this component when circuit designs require an NPN transistor capable of handling 200 V collector voltage and 200 mA current simultaneously. The 300 MHz transition frequency makes it suitable for applications demanding faster switching speeds than standard low-frequency devices. Consider the TO-220ML package for its thermal performance and mechanical stability in through-hole implementations compared to smaller surface-mount alternatives.

Single Bipolar Transistors Part Context

The 2SC4474E belongs to the family of single bipolar junction transistors manufactured by onsemi. It is categorized under power discretes, specifically designed for applications exceeding the capabilities of small-signal transistors. The device utilizes silicon technology and is packaged in a standard three-pin configuration, distinguishing it from multi-element integrated circuits or MOSFET-based solutions within the broader transistor market.

Single Bipolar Transistors Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in transition frequency or thermal resistance. Verify that any replacement maintains the 200 V V(BR)CEO and 200 mA Ic ratings to prevent circuit failure.
