SZ1SMB5930BT3G

Single Zener Diodes Overview

The SZ1SMB5930BT3G is a 3 W plastic surface mount Zener voltage regulator diode from the 1SMB59xxBT3G series. It features a nominal reverse Zener voltage of 16 V with a tolerance of ±5%, measured at a test current (IZT) of 23.4 mA. The device operates within a temperature range of −65°C to +150°C and is housed in an SMB (DO-214AA) package. Key electrical parameters include a maximum Zener impedance (ZZT) of 10 Ω, a maximum reverse leakage current (IR) of 1 µA at 12.2 V, and a forward voltage (VF) of 1.5 V max at 200 mA DC.

Single Zener Diodes Feature Summary

• Qualified for automotive applications under AEC-Q101 standards with PPAP capability.
• Features a flat handling surface designed for accurate automated placement.
• Includes modified L-bend leads providing increased contact area for bond pads.

Single Zener Diodes Applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the specific voltage and tolerance requirements for the target application. Confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the procurement channel provides valid traceability documentation required for automotive or high-reliability sectors. Check for specific marking variations associated with the SZ prefix.

Single Zener Diodes Selection Notes

Select this component when a 16 V regulation point is needed with a 3 W power dissipation capacity in an SMB package. Consider the low leakage current and tight impedance specifications for precision regulation tasks. Evaluate thermal derating curves if operating above ambient temperatures of 25°C. Verify that the package footprint aligns with the PCB design guidelines provided in the mechanical case outline.

Single Zener Diodes Part Context

This part belongs to the 1SMB59xxBT3G series of 3 W Zener diodes manufactured by onsemi. The series covers a wide voltage range from 3.3 V to 200 V. The SZ1 prefix indicates a variant qualified for automotive use, adhering to stricter quality and site control requirements compared to standard commercial versions.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other SZ1SMB59xxBT3G variants with different nominal voltages. Cross-reference with the 1SMB5930BT3G for non-automotive equivalents. Verify pinout compatibility and thermal characteristics before substituting with generic SMB Zener diodes.
