Overview
The DZ23C7V5-7 is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features two Zener diodes in a common cathode configuration within an SOT-23 package. The nominal Zener voltage is 7.5 V with a range of 7.0 to 7.9 V at a test current of 5.0 mA. Maximum Zener impedance is 7.0 Ω at IZT = 5.0 mA and 50 Ω at IZK = 1.0 mA. Power dissipation is rated at 300 mW, with a thermal resistance (junction to ambient) of 417 °C/W. Operating and storage temperature ranges span from -65 °C to +150 °C.
Feature Summary
- Dual Zener diodes integrated in a single common cathode configuration for space-efficient designs.
- High reliability qualification meeting JEDEC standards for robust performance.
- Lead-free construction fully compliant with RoHS directives and halogen/antimony free.
Applications
- Voltage reference circuits requiring stable dual references.
- Clamping applications for transient voltage suppression.
- Automated insertion processes due to SOT-23 packaging suitability.
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to commercial grade qualification and tape & reel shipping quantities of 3000 units. Confirm that the component meets the required environmental standards, specifically RoHS compliance and lead-free plating specifications, before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution in a compact SOT-23 footprint is required. Ensure the application operates within the specified power dissipation limits and temperature range. Consider the typical temperature coefficient of +0.050 %/°C for thermal stability requirements in precision voltage regulation tasks.
Part Context
This part belongs to the DZ23C series of 300mW dual surface mount Zener diodes. The series covers a wide voltage range from 2.7 V to 51 V. Variants are available in both common cathode and common anode configurations, with automotive-grade options featuring Q-suffixes for AEC-Q101 qualification.
Replacement Considerations
Direct substitutes include other DZ23C series parts with matching voltage ratings or AZ23 series variants for common anode configurations. Verify pinout compatibility and thermal characteristics when replacing with components from different manufacturers.
