Overview
The Nexperia BZB84-B2V7-QR is a dual voltage regulator diode in a SOT-23 (TO-236AB) package. It features a nominal Zener voltage of 2.7 V with ±2% tolerance. Total power dissipation is 300 mW, with a non-repetitive peak reverse power dissipation of 40 W. The device operates between -55 °C and +150 °C. Key electrical parameters include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 600 µA at 5 mA test current, and a diode capacitance of 450 pF. It is qualified to AEC-Q101 for automotive use.
Feature Summary
- Dual common anode configuration within a compact SOT-23 surface-mounted plastic package.
- Qualified according to AEC-Q101 standards for automotive applications.
- High non-repetitive peak reverse power dissipation capability.
Applications
- General regulation functions
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and availability status. Ensure the component matches the required automotive qualification level. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity before purchase.
Selection Notes
Select this component when a dual Zener array with precise ±2% voltage tolerance is required. The low forward voltage drop supports efficient signal handling. Verify that the 300 mW total power dissipation meets the thermal requirements of the target circuit design under expected operating conditions.
Part Context
This part belongs to the BZB84-Q series, which offers nominal working voltages from 2.4 V to 75 V. The series includes both ±2% (B series) and approximately ±5% (C series) tolerance options. All variants share the same SOT-23 footprint and AEC-Q101 automotive qualification.
Replacement Considerations
Direct replacements within the same family include BZB84-C2V7-QR for ±5% tolerance or other BZB84-Bxxx-QR variants for different voltage levels. Verify pinout compatibility and thermal characteristics before substituting.
