ZXRE330AV-A

Overview

The ZXRE330AV-A is a precision micro-power shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 3.3V with an initial accuracy tolerance of ±0.5% at +25°C. The device operates within a wide current range from 1µA to 5mA and features a low temperature coefficient of 20ppm/°C (typical). It is housed in a TO-92 package and supports an extended operating temperature range from -40°C to +85°C.

Feature Summary

• Offers tight output voltage tolerance for high precision applications
• Maintains excellent stability without requiring external output capacitors
• Features sharp knee characteristics and low knee current consumption

Applications

• Battery-powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix 'AV' corresponds to the required TO-92 package and ±0.5% accuracy grade. Confirm that the component status aligns with project lifecycle requirements, as this part may be designated as Not Recommended for New Design (NRND) depending on the manufacturer's current production schedule.

Selection Notes

Select this component when a fixed 3.3V reference with high initial accuracy is required in a through-hole package. Ensure the design accommodates the specified operating current range of 1µA to 5mA. Verify that the thermal dissipation capabilities of the TO-92 package are sufficient for the intended ambient temperature conditions.

Part Context

This component belongs to the ZXRE330 series of precision micro-power shunt voltage references. The series includes variants in SOT-23 packages and different accuracy grades. The AV suffix specifically denotes the TO-92 package form factor with the highest precision tolerance available in this family.

Replacement Considerations

Check for ZXRE330EV-A if a lower accuracy grade (±2%) is acceptable. For surface mount alternatives, consider ZXRE330ASA-7 or ZXRE330ESA-7 in SOT-23 packages.
