Overview
The Nexperia BZB84-B27-QR is a dual voltage regulator diode in the BZB84-Q series, housed in an SOT-23 surface-mount package. It features a common anode configuration with two independent cathodes. The nominal Zener voltage is 27 V with a ±2% tolerance (Series B). Total power dissipation is limited to 300 mW, while non-repetitive peak reverse power dissipation reaches 40 W per diode. Forward voltage is 0.9 V at 10 mA. Operating temperature ranges from -55 °C to +150 °C. Reverse current is 300 μA at 2 mA test current.
Feature Summary
- Dual common anode configuration for compact circuit design
- Qualified according to AEC-Q101 for automotive applications
- High non-repetitive peak reverse power dissipation capability
Applications
- General regulation functions
- Automotive electronic systems
- Voltage reference circuits
Procurement Notes
Verify the specific ordering suffix and tape-and-reel quantity against official distributor listings before purchase. Confirm that the component meets the required AEC-Q101 qualification standards for your intended application environment. Ensure proper handling procedures are followed during assembly to maintain device integrity.
Selection Notes
Select this component when a dual-diode solution with a common anode is required in a small SOT-23 footprint. The ±2% tolerance series provides tighter voltage accuracy compared to the ±5% option. Verify thermal constraints as total power dissipation is limited to 300 mW across both diodes.
Part Context
This part belongs to the Nexperia BZB84-Q series of dual voltage regulator diodes. The series offers various nominal working voltages from 2.4 V to 75 V in the E24 range. All variants share the same SOT-23 plastic package and AEC-Q101 automotive qualification, differing primarily in Zener voltage and tolerance series.
Replacement Considerations
Direct substitutes within the same family include BZB84-C27-Q for ±5% tolerance or other BZB84-Q series variants with matching voltage ratings. Cross-package replacements require verifying pin compatibility and thermal performance characteristics.
