Overview
The DZ23C9V1-G3-18 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 ±5% tolerance and operates at a test current of 5 mA. The device provides a dynamic resistance of 10 Ω and maintains a reverse leakage current of 0.1 μA at 7 V. Designed for commercial applications, it supports power dissipation up to 500 mW on leads and 300 mW on FR-4 boards, functioning reliably within an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Silicon planar construction with E24 standard grading
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
- Green commercial grade compliant with RoHS3
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific suffix '-18' against official documentation to confirm the 10,000-unit reel packaging format. Ensure that the 'G3' designation aligns with required environmental compliance standards for the target assembly process before finalizing procurement orders.
Selection Notes
Select this component when a 9.1 V Zener voltage with tight ±5% tolerance is required in a compact SOT-23 footprint. Consider the 5 mA test current and 10 Ω dynamic resistance for precise regulation needs. Verify thermal management requirements against the 300 mW dissipation limit on standard PCB footprints.
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 performance characteristics across various voltage grades for general-purpose electronic designs.
Replacement Considerations
Consult the manufacturer's datasheet or authorized distributors for verified parameter-equivalent alternatives. Cross-referencing requires matching the 9.1 V nominal voltage, ±5% tolerance, SOT-23 package, and 300 mW power dissipation limits to ensure functional compatibility.
