Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMBZ30VALT116 are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The critical parameters that determine substitution eligibility are:

• Voltage - Reverse Standoff: 24V (Max)
• Voltage - Breakdown (Min): 28.5V
• Voltage - Clamping (Max) @ Ipp: 43V
• Current - Peak Pulse (10/1000µs): 950mA
• Power - Peak Pulse: 40W
• Unidirectional Channels: 2
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

The MMBZ30VALYT116 qualifies as a direct substitute because it maintains identical electrical specifications across all critical voltage and current parameters, operates in the same SOT-23 package family, and shares the same surface-mount configuration. Both parts are manufactured by Rohm Semiconductor and carry active product status with ROHS3 compliance.
