MMBZ24VALT116 Equivalent & Substitute Parts

Part Overview

The MMBZ24VALT116 is a transient voltage suppressor (TVS) diode manufactured by Rohm Semiconductor, designed for general-purpose voltage clamping applications. This surface-mount component operates with a 22V reverse standoff voltage and 32V maximum clamping voltage, providing 1.25A peak pulse current capability in a compact SOT-23 package. The part is currently in active production status with 787 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative packaging formats are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMBZ24VALT116 is determined by the following critical electrical and mechanical parameters:

• Voltage Rating Compatibility: Reverse standoff voltage and breakdown voltage must support the same or lower voltage protection threshold
• Current Handling: Peak pulse current rating must equal or exceed 1.25A
• Clamping Voltage: Maximum clamping voltage at peak pulse current must not exceed 32V
• Package Compatibility: Surface-mount SOT-23-3 package format required for direct board-level substitution
• Zener Type: Dual-channel unidirectional TVS diode configuration
• Compliance Status: RoHS3 compliance and REACH unaffected status maintained

The MMBZ24VALYT116 qualifies as a substitute part based on matching electrical performance specifications (1.25A peak pulse current, 32V clamping voltage, 40W peak pulse power) and identical package format (SOT-23-3). The primary difference is the reverse standoff voltage rating of 20V versus 22V on the main part, which represents a lower protection threshold suitable for applications with reduced voltage stress requirements.

Engineering Selection Recommendations

Both the MMBZ24VALT116 and MMBZ24VALYT116 maintain active production status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance for current and future applications. Selection between these parts is based on voltage protection requirements and packaging format availability.

The MMBZ24VALT116 is specified for applications requiring 22V reverse standoff voltage protection. The MMBZ24VALYT116 provides equivalent electrical performance with a 20V reverse standoff voltage and is supplied in Tape & Reel packaging format, offering higher inventory availability (3625 units in stock versus 787 units). The MMBZ24VALYT116 is suitable for applications where the lower voltage threshold does not compromise circuit protection requirements.

Both parts share identical clamping voltage (32V), peak pulse current (1.25A), and power dissipation (40W) specifications, ensuring functional equivalence in transient suppression performance. Package format remains consistent across both variants (SOT-23-3), enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MMBZ24VALYT116 directly replace the MMBZ24VALT116 in existing designs?

A: Direct substitution is possible when the application voltage stress does not exceed the 20V reverse standoff threshold of the MMBZ24VALYT116. Both parts share identical SOT-23-3 package dimensions, clamping voltage (32V), and peak pulse current (1.25A) specifications. Verify that your circuit protection requirements align with the lower 20V standoff voltage before implementing this substitution.

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

A: The primary difference is the reverse standoff voltage rating: MMBZ24VALT116 operates at 22V, while MMBZ24VALYT116 operates at 20V. Both parts are manufactured by Rohm Semiconductor and share identical electrical performance for clamping voltage, peak pulse current, and power dissipation. The MMBZ24VALYT116 is supplied in Tape & Reel packaging format.

Q: Are both parts RoHS3 compliant?

A: Yes, both the MMBZ24VALT116 and MMBZ24VALYT116 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What packaging formats are available?

A: Both parts are supplied in SOT-23-3 surface-mount package format. The MMBZ24VALT116 is available in standard packaging, while the MMBZ24VALYT116 is supplied in Tape & Reel format for automated assembly processes.

Q: Can these parts be used interchangeably in high-voltage protection circuits?

A: Interchangeability depends on the specific voltage protection threshold required by your application. The MMBZ24VALT116 with 22V reverse standoff voltage is suitable for circuits requiring protection up to 22V. The MMBZ24VALYT116 with 20V reverse standoff voltage is appropriate for lower-voltage applications. Both parts provide identical 32V maximum clamping voltage performance.
