DZ23C33-E3-08

Overview

The DZ23C33-E3-08 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 at a test current of 2 mA and features a maximum reverse leakage current of 50 µA at 38 V. Dynamic resistance is specified at 80 Ω, with a temperature coefficient ranging from 8 to 10 x 10⁻⁴/°C. Power dissipation reaches 500 mW on a lead base and 300 mW on an FR-4 board, supporting an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable small-signal regulation
• Dual common cathode configuration within a compact SOT-23 footprint
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable low-power regulation
• Protection against electrostatic discharge in sensitive electronics
• General-purpose clamping applications in consumer devices

Procurement Notes

Verify that the specific part number matches the required electrical parameters before integration. Confirm compliance with RoHS directives and material categorization standards as defined by the manufacturer. Ensure storage conditions align with moisture sensitivity level requirements to maintain component integrity during assembly processes.

Selection Notes

Select this component when a dual common cathode arrangement is necessary within a limited board area. Consider the thermal resistance characteristics if power dissipation exceeds standard limits. Validate the temperature coefficient against the specific environmental operating conditions of the target application to ensure long-term stability.

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 suffix indicates RoHS compliance for commercial grade applications, distinguishing it from the HE3_A variant which carries AEC-Q101 automotive qualification.

Replacement Considerations

Direct substitutes include other Vishay DZ23 series parts with identical configurations or equivalent Zener voltages. Cross-manufacturer replacements must match the SOT-23 package dimensions and verify that dynamic resistance and leakage currents fall within acceptable design margins.
