Overview
The BZX84C30S-7-F is a dual surface mount Zener diode from Diodes Incorporated, housed in an SOT-363 package. It provides a nominal Zener voltage of 30V with a tolerance range of 28.0V to 32.0V at a test current of 2.0mA. The device features a maximum Zener impedance of 80Ω at IZT and 300Ω at ZZK (0.5mA). It supports a power dissipation of 200mW and operates within a temperature range of -65°C to +150°C. The component is lead-free, RoHS compliant, and utilizes planar die construction for reliability.
Feature Summary
- Planar die construction ensures robust performance in surface mount applications.
- Ultra-small SOT-363 package design facilitates space-constrained circuit layouts.
- Lead-free and RoHS compliant manufacturing meets environmental standards.
Applications
- Voltage reference circuits requiring stable potential levels.
- Overvoltage protection for sensitive electronic components.
- Clamping applications in signal processing paths.
Procurement Notes
Verify the complete part number including the suffix -7-F to confirm tape and reel packaging quantity of 3000 units. Ensure compatibility with SOT-363 footprint dimensions during PCB layout. Confirm date code markings align with project requirements for material traceability and storage conditions.
Selection Notes
Select this component when a 30V Zener voltage is required in a dual-diode package format. Consider the 200mW power dissipation limit and thermal resistance of 625°C/W for heat management. Verify that the 2.0mA test current matches the operating conditions of the target circuit design.
Part Context
This part belongs to the BZX84C series of dual Zener diodes offered by Diodes Incorporated. The series covers voltages from 2.4V to 39V in the SOT-363 case. The BZX84C30S-7-F specifically denotes the 30V variant with standard packaging suffixes indicating reel distribution.
Replacement Considerations
Direct substitutes include other BZX84C30S variants from different manufacturers if pinout and electrical characteristics match. Verify package dimensions and marking codes to ensure mechanical compatibility without redesigning the PCB footprint.
