Overview
The DZ23C5V1-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 5.1 V with a ±5% tolerance and operates at a test current of 5 mA. The device provides a maximum reverse leakage current of 0.1 µA at 4.85 V and exhibits a dynamic resistance of 60 Ω at the test current. Electrical characteristics are specified over an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Dual-element common cathode configuration within a compact SOT-23 footprint
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant commercial grade construction without automotive qualification
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Clamping applications for transient voltage suppression
- Biasing networks in small signal processing stages
Procurement Notes
Verify that the specific ordering suffix matches the required reel quantity and tape specifications. Confirm compliance requirements against the latest Vishay material categorization documentation. Ensure the component meets the intended environmental conditions before finalizing procurement orders.
Selection Notes
Select this part when a dual Zener array in an SOT-23 package is required. Verify that the 5.1 V nominal voltage aligns with circuit design parameters. Consider thermal dissipation limits if operating near maximum ambient temperatures or utilizing high pulse currents.
Part Context
This component belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded Zener voltages according to the E24 standard. The base product line includes both commercial and AEC-Q101 qualified variants depending on the specific ordering code.
Replacement Considerations
Check for equivalent parts within the same DZ23 series featuring different voltage ratings or packaging options. Verify compatibility with existing board footprints and soldering profiles. Confirm that alternative components meet the same electrical tolerances and thermal performance criteria.
