DZ23C9V1-G3-08

Overview

The DZ23C9V1-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and provides a maximum reverse leakage current of 0.1 µA at 7 V. Dynamic resistance is specified at 10 Ω, with a temperature coefficient ranging from 5 to 8 x 10⁻⁴/°C. Power dissipation reaches 500 mW on lead-mounted configurations and 300 mW on FR-4 boards. Operating temperatures span from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• Graded Zener voltages according to international E24 standard
• ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
• Green commercial grade material categorization

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection in low-power electronic systems
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and check for AEC-Q101 automotive qualification if required by specific application standards. Ensure ordering suffixes match desired reel quantities and tape specifications before finalizing procurement orders.

Selection Notes

Select this component when a 9.1 V reference is needed in a compact SOT-23 footprint. Consider the 5% tolerance and dynamic resistance values for precision requirements. Evaluate thermal management needs based on the 300 mW dissipation limit on PCBs versus higher lead-mounted ratings.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, offering standardized tolerances and consistent packaging across multiple voltage options for design flexibility.

Replacement Considerations

Direct substitutes within the same series include other DZ23C variants with different Zener voltages but identical packages. Cross-brand replacements require matching SOT-23 pinouts, voltage ratings, and power dissipation capabilities.
