Overview
The SZMMBZ16VALT1G is a dual monolithic silicon Zener transient voltage suppressor in an SOT-23 package. It features a common anode design for protecting two separate lines. The working peak reverse voltage is 13 V, with a breakdown voltage range of 15.20 V to 16.80 V at a test current of 1.0 mA. The maximum clamping voltage is 23 V at a peak pulse current of 1.7 A. It handles 40 W peak power and offers ESD protection up to ±30 kV contact discharge.
Feature Summary
- Dual common anode configuration protects two independent signal lines within a single compact package.
- AEC-Q101 qualified with PPAP capability, suitable for automotive applications requiring unique site control.
- Provides robust ESD protection meeting IEC61000-4-2 Level 4 standards with low leakage current.
Applications
- Computer interface protection
- Microprocessor data bus and address bus protection
- Printer and business machine I/O protection
Procurement Notes
Verify the presence of the 'SZ' prefix to confirm automotive qualification and specific manufacturing site requirements. Ensure the ordering suffix matches the desired tolerance and packaging format. Confirm compliance with RoHS directives and lead-free status before finalizing procurement specifications.
Selection Notes
Select this component when board space is limited and dual-line protection is required. Choose the unidirectional variant for standard DC line protection. Verify that the operating voltage remains below the 13 V working peak reverse voltage rating to prevent excessive leakage during normal operation.
Part Context
This device belongs to the MMBZ16V series of 40 Watt peak power Zener TVS diodes. It shares the same electrical characteristics as the MMBZ16VALT1G but includes the SZ prefix to denote automotive-grade qualification and traceability requirements defined by AEC-Q101 standards.
Replacement Considerations
The MMBZ16VALT1G serves as a direct functional replacement. Other members of the MMBZ16V series may be substituted if voltage ratings align. Verify package compatibility and thermal dissipation requirements when replacing with similar SOT-23 TVS devices.
FAQ
What is the pin configuration for the SZMMBZ16VALT1G?
Pin 1 is Cathode 1, Pin 2 is Cathode 2, and Pin 3 is the Common Anode.
Does the SZ prefix affect the electrical performance compared to the standard version?
No, the electrical parameters are identical. The SZ prefix indicates AEC-Q101 qualification and specific manufacturing site controls.
What is the maximum clamping voltage for this device?
The maximum clamping voltage is 23 V when subjected to a peak pulse current of 1.7 A.
