Overview
The DZ23C43-G3-08 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 43 V with a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 500 mW on lead-mounted configurations or 300 mW on FR-4 boards. Electrical characteristics include a reverse leakage current of 50 μA maximum at 32 V and a dynamic resistance of 97 Ω at a test current of 2 mA.
Feature Summary
- Silicon planar construction for stable voltage regulation
- ESD protection capability exceeding 8 kV via human body model
- Compliant with RoHS standards and free of halogenated substances
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in low-power electronic assemblies
Procurement Notes
Verify component authenticity by cross-referencing the ordering code against official manufacturer documentation. Confirm that the specific part number matches the required voltage grade and tolerance specifications before finalizing acquisition. Ensure storage conditions align with moisture sensitivity level requirements to maintain device integrity during handling.
Selection Notes
Select this component when a single Zener diode with a 43 V breakdown voltage is required in a compact SOT-23 footprint. Consider the thermal resistance values if operating near maximum power dissipation limits. Verify that the circuit design accommodates the specified dynamic resistance and leakage current parameters for optimal performance.
Part Context
This device belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded Zener voltages from 2.2 V to 75 V, all adhering to the international E24 standard. These components are designed for general-purpose voltage regulation tasks in commercial electronics.
Replacement Considerations
Direct substitutes within the same series include other DZ23Cxx-G3-08 variants with different voltage ratings. For identical electrical characteristics, verify availability of equivalent parts from authorized distributors. Cross-reference pinout compatibility and thermal management requirements when considering alternative manufacturers.
