Overview
The Nexperia BZB84-B2V4-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 (TO-236AB) surface-mounted package. It features a dual common anode configuration with two independent cathodes. The nominal Zener voltage is 2.4 V with a ±2% tolerance range of 2.35 V to 2.45 V. Key electrical parameters include a maximum reverse current of 600 μA at 2V, a differential resistance of 600 Ω at IZ=5 mA, and a temperature coefficient of -3.5 mV/K. The device supports a total power dissipation of 300 mW and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration providing two independent regulation channels in a single compact package.
- Qualified according to AEC-Q101 standards for automotive applications.
- High non-repetitive peak reverse power dissipation capability of up to 40 W per diode.
Applications
- General voltage regulation functions
- Automotive electronic circuits
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm package type and tolerance grade. Ensure the component matches the required AEC-Q101 qualification status if used in automotive designs. Cross-reference the marking code 'V9%' on the physical device to validate authenticity and part identity before integration into production.
Selection Notes
Select this component when a dual-channel voltage reference is required in a space-constrained design. The BZB84-B2V4-QR is suitable for low-voltage regulation tasks requiring tight tolerance. Consider the negative temperature coefficient for thermal stability analysis. Verify that the 300 mW total power dissipation limit accommodates the expected operating conditions of both diodes simultaneously.
Part Context
This part belongs to the BZB84-Q series of dual voltage regulator diodes manufactured by Nexperia. The series offers various nominal voltages from 2.4 V to 75 V in the E24 range. All variants share the same SOT-23 plastic package and dual common anode topology, differing primarily in Zener voltage specifications and tolerance grades.
Replacement Considerations
Direct substitutes within the same family include BZB84-C2V4-QR for ±5% tolerance or other BZB84-Q series variants with different voltage ratings. Ensure any replacement maintains the SOT-23 footprint and dual common anode pinout compatibility.
