MMBZ24VALFHT116 Equivalent & Substitute Parts

Part Overview

The MMBZ24VALFHT116 is a dual-channel Zener transient voltage suppressor (TVS) diode manufactured by Rohm Semiconductor in SSD3 surface mount packaging. This component provides 20V reverse standoff voltage with 32V maximum clamping voltage and 1.25A peak pulse current capability, designed for transient overvoltage protection in automotive and industrial applications. The part maintains Active product status with AEC-Q101 automotive qualification and ROHS3 compliance. Substitute parts are identified when electrical specifications, mechanical compatibility, and regulatory certifications remain equivalent across packaging variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMBZ24VALFHT116 is determined by equivalence across the following critical parameters:

Voltage specifications: Reverse standoff voltage of 20V (Max), breakdown voltage minimum of 22.8V, and clamping voltage maximum of 32V must remain identical.

Current and power ratings: Peak pulse current of 1.25A at 10/1000µs pulse width and peak pulse power of 40W must be maintained.

Channel configuration: Dual-channel (2 unidirectional channels) topology is required.

Thermal performance: Operating temperature rating of 150°C (TJ) must be met or exceeded.

Package compatibility: Surface mount configuration with TO-236-3, SC-59, or SOT-23-3 case outline.

Regulatory compliance: Automotive grade with AEC-Q101 qualification, ROHS3 compliance, and MSL 1 rating must be preserved.

The MMBZ24VALYFHT116 qualifies as a direct substitute based on identical electrical specifications and regulatory certifications. The primary distinction is packaging format: the main part uses Cut Tape (CT) while the substitute uses Tape & Reel (TR) format, both compatible with automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the MMBZ24VALFHT116 and MMBZ24VALYFHT116 maintain Active product status with full AEC-Q101 automotive qualification and ROHS3 compliance. Selection between these parts should be based on supply chain requirements and assembly process specifications. The Cut Tape format of the main part suits lower-volume or manual assembly operations, while the Tape & Reel format of the substitute accommodates high-volume automated pick-and-place assembly. Both parts carry identical electrical performance, thermal ratings, and regulatory certifications, making them functionally interchangeable in circuit design and application.

Frequently Asked Questions (FAQ)

Q: Can MMBZ24VALYFHT116 replace MMBZ24VALFHT116 in production?

A: Yes. Both parts are electrically identical with matching voltage specifications (20V standoff, 32V clamping), current ratings (1.25A peak pulse), and thermal performance (150°C). The difference is packaging format: Cut Tape versus Tape & Reel. Assembly process compatibility should be verified with your manufacturing partner.

Q: Are there differences in reliability or lifespan between these parts?

A: No. Both parts carry identical AEC-Q101 automotive qualification, ROHS3 compliance, and MSL 1 rating. Reliability and lifespan are equivalent.

Q: What does the packaging format difference mean for my application?

A: Cut Tape (CT) packaging is suitable for manual component handling and lower-volume assembly. Tape & Reel (TR) packaging is optimized for automated assembly equipment. The electrical and mechanical performance of the component itself is unchanged.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry Automotive grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: Can I mix these parts in the same production batch?

A: Yes, from an electrical and functional perspective. However, assembly process compatibility should be confirmed with your manufacturing facility, as different packaging formats may require different handling procedures.
