BZB84-B75,215

Overview

The Nexperia BZB84-B75,215 is a dual common anode Zener diode array housed in a TO-236AB (SOT-23) surface-mount package. It features a nominal Zener voltage of 75 V with a tight tolerance of ±2%. The device supports a total power dissipation of 300 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum reverse leakage current of 50 nA at 52.5 V, a forward voltage of 0.9 V at 10 mA, and a differential resistance of 255 Ω. It is qualified under the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual common anode configuration for compact circuit design
• High precision ±2% voltage tolerance series
• Automotive grade qualification compliant with AEC-Q101
• Small plastic SMD package suitable for high-density layouts

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component when a dual Zener array with high voltage accuracy is required in a small footprint. The ±2% tolerance distinguishes it from the C-series (±5%). Ensure the 75 V rating matches the target regulation point and that the 300 mW power budget accommodates the expected operating current and ambient thermal conditions.

Part Context

This part belongs to the BZB84 series of dual Zener diodes from Nexperia. The series offers various voltage options ranging from 2.4 V to 75 V in both ±2% (B-series) and ±5% (C-series) tolerances. All variants share the same SOT-23 package and pinout, facilitating design flexibility across different voltage requirements while maintaining consistent physical dimensions.

Replacement Considerations

Direct functional substitutes with identical pinout and specifications include the BZX84-B75-QR (single diode, requires two units) or other BZB84-B75 variants from different manufacturers if pin-compatible. Verify that any replacement maintains the ±2% tolerance and AEC-Q101 qualification if automotive reliability is required.
