Overview
The DZ23C3V3-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 3.3 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 5 μA at 1 V. Dynamic resistance is specified at 95 Ω (max) at the test current, with a temperature coefficient ranging from -8 to -3 x 10⁻⁴/°C. Power dissipation is rated at 300 mW on an FR-4 board, supporting an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for reliable small-signal regulation
- ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant commercial grade material categorization
Applications
- Voltage reference circuits requiring stable low-voltage rails
- Clamping applications for signal line protection
- Biasing networks in analog electronic systems
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with RoHS directives and material categorization requirements before finalizing procurement orders.
Selection Notes
Select this component when a precise 3.3 V reference is needed within a compact SOT-23 footprint. Consider the negative temperature coefficient for thermal stability analysis. Verify that the 300 mW power dissipation rating aligns with the expected thermal environment on the target PCB layout.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of graded Zener voltages according to the E24 standard, providing designers with standardized options for various voltage regulation needs in consumer and industrial electronics.
Replacement Considerations
Direct substitutes include other DZ23 series variants with identical packaging and electrical characteristics but different voltage ratings, such as DZ23C3V0 or DZ23C3V6. Cross-brand replacements must match the SOT-23 package, 3.3 V nominal voltage, and ±5% tolerance specifications.
