BZX84W-C75-QX

Single Zener Diodes Overview

The Nexperia BZX84W-C75-QX is a general-purpose Zener diode from the BZX84W-Q series, designed for surface-mount applications. It operates within a nominal voltage range of 2.4 V to 75 V and features a ±5% tolerance variant. The device is housed in a leadless SOT323 (SC-70) plastic package with three leads. Key electrical parameters include a total power dissipation of 275 mW at 25 °C, a maximum forward voltage of 0.9 V at 10 mA, and a reverse current of 50 nA at 0.7 times the nominal Zener voltage. It supports an ambient temperature range of -55 °C to +150 °C and has been qualified according to AEC-Q101 standards.

Single Zener Diodes Procurement Notes

Verify the specific suffix against official Nexperia documentation to confirm packaging configuration and manufacturing site codes. Ensure the selected component matches the required AEC-Q101 qualification status if intended for automotive use. Cross-reference the marking code table to validate part identification on the physical device. Confirm that the ordering information aligns with the requested tolerance series and package version before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a compact surface-mount solution is required for voltage regulation or high-frequency tasks. The BZX84W-C75-QX offers a specific 75 V nominal voltage with 5% tolerance. Consider the thermal resistance and power dissipation limits relative to the PCB footprint. Verify compatibility with standard reflow or wave soldering processes using the provided footprint dimensions. Ensure the operating environment stays within the specified junction and ambient temperature ranges.

Single Zener Diodes Part Context

This device belongs to the BZX84W-Q series, which comprises 74 types with nominal working voltages ranging from 2.4 V to 75 V. The series includes both ±2% and ±5% tolerance options. All variants share the same SOT323 leadless package and are designed for general-purpose Zener regulation. The 'Q' designation indicates automotive qualification under AEC-Q101 standards.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other BZX84W-Q variants with different nominal voltages but identical packages and qualifications. For example, BZX84W-C68-Q or BZX84W-C82-Q may be considered if voltage requirements differ. Ensure any replacement maintains the SOT323 package and AEC-Q101 compliance.
