MM3Z33VB

Single Zener Diodes Overview

The MM3Z33VB is a Zener diode from the MM3Z2V4B-MM3Z75VB series, manufactured by onsemi. It features a nominal Zener voltage of 33 V with a tight tolerance of ±2%. The device operates in a SOD-323FL surface-mount package and provides a steady-state power dissipation rating of 200 mW. Key electrical characteristics include a maximum forward voltage of 1.0 V at 10 mA, a Zener impedance (ZZT) of 306 Ω at a test current (IZT) of 2 mA, and a reverse leakage current (IR) of 45 nA at 23.0 V. The component supports an operating temperature range from -65°C to +150°C.

Single Zener Diodes Feature Summary

• Offers high precision voltage regulation with a standard ±2% tolerance on the nominal Zener breakdown voltage.
• Utilizes a compact SOD-323 surface-mount package designed for applications where space is limited.
• Constructed using lead-free materials with a matte tin finish to ensure compliance with environmental standards.

Single Zener Diodes Applications

• Voltage regulation circuits requiring precise reference levels
• Protection against transient overvoltage events
• High-density printed circuit board designs

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix and marking code corresponding to the 33 V variant before procurement. Confirm that the required shipping format matches the available tape and reel specifications. Ensure the design accommodates the thermal resistance limits defined in the absolute maximum ratings to maintain reliability during operation.

Single Zener Diodes Selection Notes

Select this component when a tight voltage tolerance is critical for circuit stability. The SOD-323 package is suitable for automated assembly processes in space-constrained environments. Evaluate the thermal management requirements based on the 200 mW power dissipation limit and the junction-to-ambient thermal resistance provided in the datasheet.

Single Zener Diodes Part Context

This part belongs to the MM3Z B-Series Zener Voltage Regulators family produced by onsemi. The series covers a wide selection of breakdown voltages ranging from 2.4 V to 75 V. All devices in this portfolio share the same small body outline dimensions and low profile height, making them interchangeable regarding physical footprint while differing in electrical parameters.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include MM3Z30VB and MM3Z36VB, provided the application can accommodate their respective nominal voltages of 30 V and 36 V. Verify that any replacement maintains the ±2% tolerance requirement and the SOD-323 package compatibility.
