Overview
The SZBZX84C27LT3G is a single Zener voltage regulator diode from the BZX84CxxxLT1G series, manufactured by onsemi. It provides a nominal Zener voltage of 27 V with a standard tolerance range of 25.1 V to 28.9 V at a test current of 5 mA. The device features a maximum power dissipation of 250 mW and operates within a junction temperature range of -65°C to +150°C. Packaged in an SOT-23 (TO-236AB) surface-mount case, it exhibits a maximum Zener impedance of 80 Ohms and a typical capacitance of 70 pF.
Feature Summary
- SZ prefix indicates qualification for automotive applications requiring unique site and control change requirements, including AEC-Q101 certification and PPAP capability.
- Designed for high-density circuit board assembly with a compact SOT-23 package optimized for automated manufacturing processes.
- Features robust electrostatic discharge protection rated at Class 3 (> 16 kV) per the Human Body Model.
Applications
- Voltage regulation in cellular phones
- Voltage reference circuits in hand-held portable devices
- Voltage clamping on high density PC boards
Procurement Notes
Verify that the ordering suffix matches the required packaging quantity and tape-and-reel specifications. Confirm the presence of the SZ prefix if automotive-grade documentation or specific site traceability is mandated for the project. Ensure compliance with RoHS standards and lead-free finish requirements during component acceptance testing.
Selection Notes
Select this component when a 27 V regulation point is required in space-constrained designs. Consider the 250 mW thermal rating and ensure adequate PCB copper area for heat dissipation. Evaluate the 80 Ohm dynamic impedance against load regulation requirements and verify that the leakage current characteristics meet system standby power constraints.
Part Context
This part belongs to the BZX84CxxxLT1G series of 250 mW Zener diodes. The SZ prefix distinguishes it as an automotive-qualified variant subject to stricter production controls compared to the standard commercial BZX84CxxxLT1G version. Both share identical electrical performance and mechanical dimensions.
Replacement Considerations
Standard BZX84C27LT1G offers equivalent electrical parameters but lacks the automotive-specific site controls. Tighter tolerance alternatives include BZX84B27LT1G. Verify pinout compatibility and thermal resistance values before substituting.
