Overview
The SZBZX84C16LT3G is a Zener voltage regulator diode from onsemi, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 16 V with a tolerance range of 15.3 V to 17.1 V at a test current of 5 mA. The device features a maximum power dissipation of 250 mW and a maximum Zener impedance of 40 Ohms at the same test current. Reverse leakage current is limited to 50 nA at 11.2 V. It operates within a junction temperature range of -65°C to +150°C and carries AEC-Q101 qualification.
Feature Summary
- SZ prefix indicates automotive qualification and unique site control requirements
- AEC-Q101 qualified and PPAP capable for automotive applications
- Designed for optimal automated board assembly processes
- ESD rating of Class 3 (> 16 kV) per Human Body Model
Applications
- Cellular phones
- Hand held portables
- High density PC boards
Procurement Notes
Verify the complete part number includes the 'G' suffix for lead-free compliance. Confirm the 'SZ' prefix requirement for automotive-specific manufacturing controls. Check the specific tape and reel quantity against the ordering information section of the datasheet. Ensure the application environment meets the thermal derating guidelines provided for FR-4 or FR-5 substrates.
Selection Notes
Select this component when a standard ±6% tolerance Zener voltage is required in a compact SOT-23 footprint. The SZ prefix is mandatory for projects requiring AEC-Q101 qualification and PPAP documentation. Consider the 250 mW power dissipation limit and thermal resistance values when designing heat management strategies for high-density PCB layouts.
Part Context
This device belongs to the BZX84CxxxLT1G series of low-power Zener diodes manufactured by onsemi. The series offers various breakdown voltages from 2.4 V to 75 V in the same SOT-23 package. The SZ variant specifically targets automotive and other applications demanding strict site and change control requirements beyond standard commercial grade components.
Replacement Considerations
Standard BZX84C16LT1G devices lack the automotive qualification and site control associated with the SZ prefix. Other manufacturers offer equivalent SOT-23 Zener diodes with similar electrical characteristics, but compatibility requires verification of pinout, tolerance, and thermal performance.
