BZD27B9V1P-E3-08

Single Zener Diodes Overview

The BZD27B9V1P-E3-08 is a silicon planar Zener diode from the Vishay eSMP series, housed in an SMF (DO-219AB) surface-mount package. It provides a nominal breakdown voltage of 9.1 V with a ±2% tolerance and operates at a test current of 50 mA. The device features a maximum reverse leakage current of 10 µA and a dynamic impedance of 4 Ω. Rated for 800 mW power dissipation at 30 °C ambient temperature, it withstands non-repetitive peak surge currents up to 100 A. Operating temperatures range from -65 °C to +175 °C.

Single Zener Diodes Procurement Notes

Verify that the specific ordering code matches the required voltage tolerance and packaging format. Confirm compliance with RoHS directives and AEC-Q101 qualification status if intended for automotive deployment. Ensure thermal management aligns with the specified power derating curves for the target operating environment.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation within tight tolerances is necessary alongside high surge immunity. The SMF package offers space efficiency compared to larger through-hole alternatives. Consider the temperature coefficient and leakage specifications relative to the circuit's sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the BZD27B Series, which encompasses 43 distinct breakdown voltages ranging from 3.6 V to 200 V. All variants share the same low-profile SMF footprint and standardized electrical testing parameters, allowing for consistent design integration across different voltage requirements.

Single Zener Diodes Replacement Considerations

Direct substitutes include other Vishay parts within the BZD27B series sharing the SMF package. Cross-brand replacements must match the DO-219AB outline, 9.1 V nominal voltage, and ±2% tolerance constraints.
