MMBZ16VALFHT116 Equivalent & Substitute Parts

Part Overview

The MMBZ16VALFHT116 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Rohm Semiconductor, designed for surface mount applications in automotive-grade circuits. This component provides transient overvoltage protection with a 13V reverse standoff voltage and 23V maximum clamping voltage. The part is currently active in production with full AEC-Q101 automotive qualification and ROHS3 compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging format preferences, or design revision requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMBZ16VALFHT116 is determined by strict equivalence across the following critical parameters:

Voltage specifications must match exactly: 13V reverse standoff voltage, 15.2V minimum breakdown voltage, and 23V maximum clamping voltage at peak pulse current.

Current and power ratings must be identical: 1.7A peak pulse current (10/1000µs) and 40W peak pulse power.

Package and mounting compatibility must be maintained: Surface mount technology with TO-236-3/SC-59/SOT-23-3 package footprint.

Automotive qualification and compliance certifications must be present: AEC-Q101 qualification, ROHS3 compliance, and active product status.

The substitute part MMBZ16VALYFHT116 meets all electrical parameter requirements and maintains automotive-grade certification. The primary difference is packaging format (Tape & Reel versus Cut Tape) and channel configuration (dual-line versus single-line), which do not affect electrical substitutability in single-channel protection applications.

Parameter Comparison

Engineering Selection Recommendations

Both MMBZ16VALFHT116 and MMBZ16VALYFHT116 are qualified for direct substitution based on identical electrical performance specifications and automotive-grade certifications. Selection between these parts should be based on the following criteria:

MMBZ16VALFHT116 (Cut Tape packaging) is appropriate for applications requiring manual component handling, small-volume assembly, or reel-to-tape conversion workflows.

MMBZ16VALYFHT116 (Tape & Reel packaging) is appropriate for high-volume automated assembly processes where continuous reel feeding is standard practice.

The dual-channel configuration of MMBZ16VALYFHT116 does not affect single-channel circuit applications, as only one channel is utilized in standard TVS protection topologies. Both parts maintain identical electrical characteristics for the active protection channel.

Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, confirming suitability for automotive and industrial applications requiring transient overvoltage suppression.

Frequently Asked Questions (FAQ)

Q: Can MMBZ16VALYFHT116 replace MMBZ16VALFHT116 in existing designs?

A: Yes. Both parts have identical electrical specifications (13V standoff, 23V clamping, 1.7A peak pulse current, 40W peak power), identical package footprint (SOT-23-3), and identical automotive qualification (AEC-Q101). The only differences are packaging format and channel count, neither of which affects electrical substitutability.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips suitable for manual assembly or small-batch operations. Tape & Reel (TR) packaging provides continuous reels for automated pick-and-place assembly systems. Both formats contain identical components with the same electrical performance.

Q: Why does MMBZ16VALYFHT116 have dual channels while MMBZ16VALFHT116 has one channel?

A: The dual-channel configuration in MMBZ16VALYFHT116 provides two independent protection paths within a single package. In single-channel applications, only one channel is active, delivering identical electrical performance to the single-channel MMBZ16VALFHT116.

Q: Are both parts suitable for automotive applications?

A: Yes. Both MMBZ16VALFHT116 and MMBZ16VALYFHT116 carry Automotive grade classification and AEC-Q101 qualification, confirming compliance with automotive reliability and quality standards.

Q: What are the critical parameters for TVS diode substitution?

A: Critical parameters include reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, package footprint, and automotive qualification status. All these parameters must match exactly between the original and substitute part.
