BZB84-B30,215

Overview

The Nexperia BZB84-B30,215 is a single Zener diode voltage regulator in the BZX84 series. It features a nominal Zener voltage of 30 V with a tight tolerance of ±2%. The device is housed in a surface-mount SOT-23 (TO-236AB) package with three pins. It supports a maximum power dissipation of 250 mW and operates within a temperature range of -65°C to +150°C. Key electrical parameters include a test current of 2 mA, a maximum Zener impedance of 80 Ω, and a maximum reverse leakage current of 50 nA. The component carries AEC-Q101 automotive qualification.

Feature Summary

• Automotive-grade reliability certified under AEC-Q101 standards for robust performance in demanding environments.
• Compact SOT-23 surface-mount packaging designed for high-density circuit board layouts.
• Tight voltage tolerance ensures precise regulation stability across operating conditions.

Applications

• Voltage reference circuits requiring stable DC levels.
• Overvoltage protection stages in automotive electronic modules.
• Clamping applications in signal conditioning paths.

Procurement Notes

Verify the complete part number including the suffix ,215 to ensure correct tape-and-reel packaging configuration. Confirm that the specific revision level matches the design requirements. Cross-reference the AEC-Q101 certification status if the application mandates strict automotive quality standards. Ensure the ordering quantity aligns with standard reel sizes to avoid cut-tape handling issues.

Selection Notes

Select this component when a 30 V regulation point is required in a compact form factor. The ±2% tolerance suits precision applications where tighter control is necessary compared to standard 5% variants. Consider the 250 mW power rating against expected thermal loads. Verify that the low leakage current meets the sensitivity requirements of the connected circuitry.

Part Context

This device belongs to the BZX84 family of single Zener diodes manufactured by Nexperia. The BZX84 series provides various voltage options in the same SOT-23 footprint, facilitating design flexibility. The BZB84 prefix typically denotes dual configurations, but datasheet listings for this specific part number identify it as a single unit within the broader BZX84 product line context.

Replacement Considerations

Check for direct equivalents from other manufacturers offering identical 30 V, 250 mW specifications in SOT-23 packages. Verify pinout compatibility and thermal characteristics before substitution. Ensure any alternative part meets the same AEC-Q101 qualification if automotive usage is intended.
