BZX8450-C2V0-QR

Single Zener Diodes Overview

The Nexperia BZX8450-C2V0-QR is a low-current voltage regulator diode housed in a SOT-23 surface-mounted device plastic package. It features a nominal Zener voltage of 2.0 V with a tolerance of approximately ±5 %. The device operates at a test current of 50 μA, making it suitable for low bias applications. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA and a total power dissipation of 250 mW. It supports an ambient temperature range from -55 °C to +150 °C and is qualified according to AEC-Q101.

Single Zener Diodes Feature Summary

• Low test current specification (50 μA) optimized for portable battery-powered applications
• Automotive qualification compliant with AEC-Q101 standards
• Small SOT-23 surface-mount package design

Single Zener Diodes Applications

• Low-current general regulation functions
• Portable battery-powered circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix 'QR' against official Nexperia documentation to confirm reel packaging details. Ensure the C-series designation matches the required approximate ±5 % tolerance for the 2.0 V rating. Confirm AEC-Q101 automotive qualification status if intended for automotive use. Cross-reference the marking code '2R%' with the datasheet to validate authenticity during inspection.

Single Zener Diodes Selection Notes

Select this component when a precise 2.0 V reference is needed in space-constrained designs. The low test current requirement minimizes power consumption compared to standard Zener diodes. Verify that the application current does not exceed the limits defined in the characteristics table. Consider the thermal resistance values if operating near the upper temperature limit.

Single Zener Diodes Part Context

This part belongs to the BZX8450-Q series of low-current voltage regulator diodes manufactured by Nexperia. The series offers working voltages from 1.8 V to 51 V in both ±2 % and ±5 % tolerance options. The Q-series suffix indicates automotive-grade qualification. The BZX8450-C2V0-QR specifically represents the lower voltage end of the C-tolerance range.

Single Zener Diodes Replacement Considerations

Check for BZX8450-B2V0-QR if tighter ±2 % tolerance is acceptable. Other BZX8450 variants may serve as substitutes if voltage and package compatibility are verified.
