BZX585B7V5

Single Zener Diodes Overview

The BZX585B7V5 is a surface-mounted Zener diode from Taiwan Semiconductor Corporation, housed in an SOD-523F package. It provides a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 200 mW of power. Key electrical characteristics include a maximum reverse leakage current of 1.0 µA and a dynamic impedance of 75 Ω. It supports high-temperature soldering at 260°C for 10 seconds and functions within a junction temperature range of -65°C to +150°C.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix (e.g., RS) against the manufacturer's official documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure that the requested component matches the exact part number and series designation provided by Taiwan Semiconductor Corporation to guarantee compliance with the stated electrical parameters and mechanical data.

Single Zener Diodes Selection Notes

Select this component when a compact footprint and precise voltage regulation are required. The SOD-523F package offers space efficiency for dense PCB layouts. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy compared to standard ±5% variants. Consider the 200 mW power dissipation limit when designing thermal management strategies for the circuit.

Single Zener Diodes Part Context

This component belongs to the BZX585B series, which covers a wide Zener voltage range from 2.4 V to 51 V. All devices in this series share the same SOD-523F package and mechanical profile, differing primarily in their specific breakdown voltage and associated electrical characteristics like dynamic impedance and leakage current.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' Zener diodes in the SOD-523F package with a 7.5 V nominal voltage and ±2% tolerance. Verify that alternative parts meet the 200 mW power dissipation rating and operate within the specified temperature range.
