The device operates within a power dissipation range up to 225 mW and is housed in an SOT-23 package. Key electrical parameters include a maximum reverse leakage current of 25 μA at 1 V and a dynamic impedance of 28 Ω at a test current of 20 mA. The component supports an operating temperature range from -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a nominal 3.3 V output and tight ±5% tolerance.
• Engineered for compact surface-mount integration using the standard SOT-23 footprint.
• Capable of reliable operation across extended industrial temperature ranges up to 150 °C.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable low-voltage sources
• Clamping and protection stages in signal processing paths
• Biasing networks in portable electronic devices

Single Zener Diodes Procurement Notes

Verify the specific suffix 'ELT1' against official onsemi documentation to confirm exact tape-and-reel packaging specifications and moisture sensitivity level. Ensure the procurement channel provides traceability to the original manufacturer. Cross-reference the datasheet revision date to validate that all electrical characteristics match the intended design requirements before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a compact SOT-23 form factor is required for 3.3 V regulation. Compare the 225 mW power rating against thermal constraints in the target application. Verify that the 28 Ω dynamic impedance meets noise and stability requirements for the specific circuit topology. Confirm compatibility with automated pick-and-place equipment due to the small outline dimensions.

Single Zener Diodes Part Context

This part belongs to the MMBZ5226B series of Zener voltage regulators from onsemi. These components are silicon planar junction devices optimized for general-purpose voltage regulation tasks. The series offers various power ratings and packages, with the ELT1 variant specifically utilizing the SOT-23 case style for high-density PCB layouts.

Single Zener Diodes Replacement Considerations

Direct substitutes include MMBZ5226BLT1G and MMBZ5226BT1G, which share identical electrical characteristics but may differ in packaging suffixes or reel quantities. Verify pinout compatibility and thermal performance when swapping between these variants.
