• Unidirectional voltage regulation capability

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Microchip Technology to ensure component authenticity. Check datasheets for exact thermal resistance values and maximum operating temperature limits before integration into final designs.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 4.7 V Zener voltage in a small surface-mount form factor. Ensure the circuit current does not exceed the 0.5 W power dissipation limit at the expected ambient temperature. Consider the ±5% tolerance when designing precision voltage references.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family used for voltage regulation. The BUR designation typically indicates a specific manufacturing lot or variant within the Microchip portfolio, while TR denotes reel packaging. It serves as a surface-mount alternative to through-hole axial packages like DO-35.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5230B from other manufacturers in DO-35 packages, though pinout and mounting differ. Surface-mount equivalents in MLL34 or SOD-80 packages should be verified for matching voltage, power, and tolerance specifications.
