Overview
The DZ23C4V3-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 4.3 V with a 5% tolerance and a power dissipation rating of 300 mW. The device utilizes an SOT-23 surface-mount package, measuring 3.04 mm in length, 1.4 mm in width, and 1.12 mm in height. It operates within a temperature range of -55 °C to +150 °C and has a maximum reverse leakage current of 100 nA at 32 V.
Feature Summary
- Dual common cathode configuration for space-efficient circuit design
- Automotive-grade qualification ensuring reliability under rigorous conditions
- Low thermal mass construction suitable for high-speed switching applications
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection stages in sensitive electronic systems
- Clamping applications in automotive electronics modules
Procurement Notes
Verify the specific suffix against official MCC documentation to confirm exact electrical tolerances and packaging options. Ensure compatibility with AEC-Q101 standards if used in automotive contexts. Cross-reference datasheet parameters with system requirements before finalizing procurement decisions.
Selection Notes
Select this component when a dual Zener configuration in an SOT-23 package is required. Consider the 300 mW power rating and 4.3 V nominal voltage for appropriate biasing. Verify that the 5% voltage tolerance meets the precision requirements of the target application.
Part Context
This part belongs to the DZ23 series of dual Zener diodes from Micro Commercial Components. It shares the SOT-23 footprint with other variants in the family but differs in internal resistor networks or voltage ratings. The 'TP' suffix typically denotes tape and reel packaging for automated assembly processes.
Replacement Considerations
The Vishay Semiconductors DZ23C4V3-G3-08 is a confirmed substitute offering identical 4.3 V specifications and SOT-23-3 packaging. Both devices share the same 300 mW power dissipation rating and dual common cathode configuration.
