Overview
The DZ23C28-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 28 V with a power dissipation rating of 300 mW. The component utilizes an SOT-23-3 surface-mount package and supports installation via SMD/SMT mounting styles. It is qualified under the AEC-Q101 standard for automotive applications. The device operates within a temperature range from -55 °C to +150 °C junction temperature. Factory packaging quantity is listed as 3000 units.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Dual common cathode configuration in compact SOT-23-3 package
- Surface-mount design optimized for automated assembly
Applications
- Voltage reference circuits in automotive instrument clusters
- Transient voltage suppression in digital dashboards
- Real-time vehicle data signal conditioning
Procurement Notes
Verify current availability through authorized distributors, as stock status varies. Confirm RoHS compliance and specific ordering suffixes match project requirements. Check lead times for reel quantities against production schedules. Ensure the AEC-Q101 qualification meets automotive grade specifications before finalizing procurement orders.
Selection Notes
Select this component when a 28 V Zener reference is required in space-constrained automotive designs. The SOT-23-3 package suits high-density PCB layouts. Verify that the 300 mW power rating aligns with thermal management capabilities. Consider the dual common cathode structure if multiple voltage references are needed in a single footprint.
Part Context
This part belongs to the DZ23C series of Zener diodes from MCC. Similar parts include DZ23C10-TP, DZ23C18-TP, DZ23C30-TP, and DZ23C68-TP, which share the same package and power ratings but differ in Zener voltage values. The series is designed for general-purpose and automotive electronics applications requiring reliable voltage regulation.
Replacement Considerations
Direct substitutes within the same family include DZ23C27-TP or DZ23C30-TP if voltage tolerance allows. Cross-brand replacements require matching SOT-23-3 package, 300 mW power rating, and AEC-Q101 qualification. Verify pinout compatibility and thermal characteristics before substitution.
