Overview
The DZ23C33-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 33 V with a standard tolerance of ±5 %. The device operates within a test current range of 0.5 to 2 mA and features a maximum reverse leakage current of 50 µA at 25 V. Dynamic resistance is specified at 80 Ω, with a temperature coefficient ranging from 8 to 10 × 10⁻⁴/°C. It supports power dissipation up to 500 mW and functions across an operating temperature range of -55 °C to +150 °C.
Feature Summary
- Silicon planar construction for reliable voltage regulation
- ESD protection exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant commercial grade configuration
Applications
- Voltage reference circuits requiring stable bias points
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in low-power electronic systems
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number against official datasheet documentation. Confirm that the ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with RoHS directives and material categorization standards before finalizing procurement orders.
Selection Notes
Select this component when a 33 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the 80 Ω dynamic resistance and specific temperature coefficient for precision requirements. Verify thermal management capabilities if ambient temperatures approach the upper operational limit of +150 °C.
Part Context
This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages according to the E24 standard. The -E3-18 suffix indicates a RoHS-compliant version supplied in 10,000-unit reels on 13-inch carriers.
Replacement Considerations
Substitute parts must match the 33 V nominal voltage, ±5 % tolerance, and SOT-23 package dimensions. Verify equivalent dynamic resistance and thermal characteristics to ensure circuit performance remains consistent during replacement.
