Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMBZ33VALT116 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 26V (Max)
• Voltage - Breakdown (Min): 31.35V
• Voltage - Clamping (Max) @ Ipp: 46V
• Current - Peak Pulse (10/1000µs): 870mA
• Power - Peak Pulse: 40W
• Unidirectional Channels: 2
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• Category: Transient Voltage Suppressors (TVS)
• Type: Zener

The MMBZ33VALYT116 qualifies as a direct substitute because it maintains identical electrical specifications across all voltage and current parameters, operates in the same package form factor, and is manufactured by the same supplier. Packaging format differences (bulk versus tape & reel) do not affect electrical compatibility or functional performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MMBZ33VALT116 and MMBZ33VALYT116 are active production components manufactured by Rohm Semiconductor with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement requirements and inventory availability rather than electrical performance, as they are electrically identical. The MMBZ33VALYT116 offers higher current inventory (3,467 units) and is supplied in tape & reel packaging, which may be advantageous for automated assembly processes. The MMBZ33VALT116 is available with 2,377 units in stock. Both parts carry unlimited moisture sensitivity level (MSL 1) classification, indicating no special storage or handling requirements beyond standard component practices.

Frequently Asked Questions (FAQ)

Q: Are MMBZ33VALT116 and MMBZ33VALYT116 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including reverse standoff voltage (26V), breakdown voltage (31.35V), clamping voltage (46V), peak pulse current (870mA), and peak pulse power (40W). They are direct functional equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. MMBZ33VALT116 is supplied in standard packaging, while MMBZ33VALYT116 is supplied in tape & reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical performance or circuit compatibility.

Q: Can I use MMBZ33VALYT116 as a drop-in replacement for MMBZ33VALT116?

A: Yes, provided your assembly process can accommodate tape & reel packaging. The component itself is identical in form factor (SOT-23-3 package) and electrical characteristics, making it suitable for direct substitution in circuit designs.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both MMBZ33VALT116 and MMBZ33VALYT116 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What applications are these TVS diodes suitable for?

A: Both parts are classified for general-purpose transient voltage suppression applications. The 26V standoff voltage and 46V clamping voltage make them suitable for protecting circuits operating in this voltage range from transient overvoltage events.
