Single Diodes Procurement Notes

Verify the specific ordering suffix to ensure the correct tape-and-reel configuration matches your automated assembly requirements. Confirm that the component meets all relevant environmental compliance standards required for your target market. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with your design specifications before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a standard NPN transistor with 100 V breakdown capability is required in a small footprint. Ensure the application current does not exceed the 300 mA limit and that thermal management can handle the 300 mW dissipation. Consider the 300 MHz frequency response for high-speed switching needs compared to lower-performance alternatives.
