BZX8850S-C4V7YL

Single Zener Diodes Overview

The Nexperia BZX8850S-C4V7YL is a low-current voltage regulator diode housed in an ultra-small SOD882BD (DFN1006BD-2) leadless surface-mount package. It features a nominal working voltage of 4.7 V with approximately ±5% tolerance, specified at a test current of 50 μA. The device supports a total power dissipation of up to 365 mW and operates within a temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a differential resistance of 80 Ω at 1 mA, and a reverse leakage current of 5.0 μA at 5 mA.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix and marking code against official Nexperia documentation to ensure correct voltage tolerance and package variant. Confirm availability status as product lifecycles may change. Ensure design compliance with absolute maximum ratings and thermal constraints during procurement planning.

Single Zener Diodes Selection Notes

Select this component for designs requiring precise low-voltage regulation in compact form factors. The DFN1006BD-2 package suits high-density PCB layouts. Consider the 50 μA test current requirement when designing bias networks to ensure accurate voltage regulation performance under actual operating conditions.

Single Zener Diodes Part Context

This part belongs to the BZX8850S series of low-current voltage regulator diodes manufactured by Nexperia. The series offers a wide working voltage range from 1.8 V to 75 V in an ultra-small SMD plastic package. These devices are designed for general-purpose regulation tasks where space constraints and low power consumption are critical design parameters.

Single Zener Diodes Replacement Considerations

Direct replacements must match the SOD882BD (DFN1006BD-2) package dimensions and pinout. Verify that substitute components offer equivalent 4.7 V Zener voltage, ±5% tolerance, and similar thermal and electrical characteristics to maintain circuit performance integrity.
