MMBZ10VALFHT116 Equivalent & Substitute Parts

Part Overview

The MMBZ10VALFHT116 is an automotive-grade Transient Voltage Suppressor (TVS) diode manufactured by Rohm Semiconductor. This dual-channel Zener diode is designed for surface mount applications in protective circuitry requiring fast transient suppression. The device is actively produced and maintains full AEC-Q101 automotive qualification with ROHS3 compliance. Substitute parts are identified when electrical performance parameters, mechanical compatibility, and qualification standards remain equivalent across manufacturing variants.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMBZ10VALFHT116 is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Reverse standoff (6.5V max), breakdown minimum (9.5V), and clamping voltage (14.2V @ Ipp)
• Current handling: Peak pulse current of 1.7A at 10/1000µs pulse width
• Power dissipation: Peak pulse power of 24W
• Package compatibility: Surface mount SOT-23-3 / TO-236-3 / SC-59 footprint
• Automotive qualification: AEC-Q101 certification required
• Compliance: ROHS3 and REACH unaffected status

The MMBZ10VALYFHT116 meets all substitution criteria. Both parts are manufactured by Rohm Semiconductor with identical electrical specifications and automotive-grade qualification. The primary difference is packaging format: the main part is supplied in standard packaging, while the substitute is available in Tape & Reel format for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the MMBZ10VALFHT116 and MMBZ10VALYFHT116 are qualified for direct substitution in automotive applications. Selection between these parts should be based on supply chain and assembly process requirements:

The MMBZ10VALFHT116 is suitable for standard procurement and manual assembly workflows. The MMBZ10VALYFHT116, supplied in Tape & Reel format, is optimized for high-volume automated pick-and-place assembly operations. Both parts carry identical AEC-Q101 automotive qualification and ROHS3 compliance certification, ensuring equivalent performance and regulatory acceptance in end-use applications.

Frequently Asked Questions (FAQ)

Q: Can MMBZ10VALYFHT116 replace MMBZ10VALFHT116 in production?

A: Yes. Both parts are electrically and mechanically identical. The substitute differs only in packaging format (Tape & Reel vs. standard packaging). Footprint, pinout, and electrical performance are equivalent.

Q: Are there any voltage or current rating differences between these parts?

A: No. Both parts maintain identical voltage ratings (6.5V standoff, 9.5V breakdown minimum, 14.2V clamping) and current handling (1.7A peak pulse). Power dissipation and operating temperature ranges are also equivalent.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the MMBZ10VALFHT116 and MMBZ10VALYFHT116 carry AEC-Q101 automotive qualification and are ROHS3 compliant. They are suitable for automotive-grade applications without additional qualification testing.

Q: What is the difference between SSD3 and SOT-23 package designations?

A: SSD3 and SOT-23-3 refer to the same physical package format (3-pin surface mount). The designations reflect different supplier naming conventions for the identical mechanical and electrical footprint.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The parts are pin-compatible and electrically equivalent. PCB layout and schematic designs require no modification for substitution.
