• Designed for switching applications with defined saturation characteristics

Applications

• General-purpose switching circuits
• Driver stages for relays and small loads
• Logic level translation interfaces

Procurement Notes

Verify the specific suffix E6393 against official Infineon documentation to confirm tape-and-reel specifications and marking codes. Confirm availability status as distribution channels may list obsolete or end-of-life variants. Ensure the ordering part number matches the required packaging format before finalizing procurement orders.

Selection Notes

Select this component when an NPN digital switch with 50V rating and 500mA capacity is required in a SOT-23-3 package. Verify that the internal resistor ratio meets the drive requirements of the controlling logic source. Check thermal dissipation limits for the intended operating environment.

Part Context

This part belongs to the BCR series of digital transistors, which combine BJTs with built-in resistors to simplify circuit design. The series offers various configurations and resistor ratios to accommodate different logic families and switching speeds within compact surface-mount packages.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may differ in hFE gain, leakage currents, or internal resistor tolerances. Validate pinout compatibility and electrical parameters before implementation.
