BZX84C9V1-E3-08

Single Zener Diodes Overview

The BZX84C9V1-E3-08 is a silicon planar Zener diode from the Vishay BZX84 series, designed for voltage regulation in surface-mount applications. It features a nominal Zener voltage of 9.1 V with a standard tolerance of ±5%, indicated by the 'C' designation. The device operates within a test current range of 2 to 5 mA and is housed in an SOT-23 package. It supports a maximum power dissipation of 300 mW on an FR-4 board and functions across an operating temperature range of -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Silicon planar construction with Zener voltages graded according to the international E24 standard
• ESD capability compliant with AEC-Q101 standards, exceeding 8 kV human body model and 800 V machine model thresholds
• RoHS-compliant commercial grade construction without lead content

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in signal conditioning paths
• Clamping applications for transient suppression

Single Zener Diodes Procurement Notes

Verify that the ordering code matches the required voltage tolerance; replace the 'C' suffix with 'B' if a tighter ±2% tolerance is necessary. Confirm the tape and reel configuration aligns with automated assembly requirements. Ensure compliance with RoHS directives for commercial grade usage. Check for specific AEC-Q101 qualification needs, which require the HE3_A suffix variant rather than the standard E3 version.

Single Zener Diodes Selection Notes

Select this component when a standard 9.1 V regulation point is needed in a compact SOT-23 footprint. Consider the dynamic resistance and leakage current specifications at the intended operating current. Evaluate thermal management capabilities, as power dissipation drops significantly above ambient temperatures. Verify that the single circuit configuration meets the design topology requirements.

Single Zener Diodes Part Context

This part belongs to the BZX84 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of nominal voltages from 2.2 V to 75 V. The 'E3' suffix denotes a lead-free, RoHS-compliant commercial grade product. The '08' suffix indicates packaging in 8 mm tape on a 7-inch reel with a minimum order quantity of 15,000 units.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering SOT-23 packaged Zener diodes with a 9.1 V nominal voltage and ±5% tolerance. Ensure equivalent thermal resistance and maximum junction temperature ratings are met. Verify pinout compatibility, specifically identifying the anode, no-connect, and cathode terminals.
