MMBZ20VALT116 Equivalent & Substitute Parts

Part Overview

The MMBZ20VALT116 is a transient voltage suppressor (TVS) diode manufactured by Rohm Semiconductor, designed for general-purpose overvoltage protection in surface-mount applications. This dual-channel Zener diode operates with a 17V reverse standoff voltage and provides 28V maximum clamping voltage at peak pulse current. The component is actively produced and widely stocked, with 1,400 units available in new original condition. Finding equivalent parts may be necessary for supply chain optimization, packaging format preferences, or inventory management across manufacturing facilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMBZ20VALT116 is determined by strict electrical and mechanical parameter matching within the TVS diode category. The following parameters define acceptable equivalents:

• Voltage - Reverse Standoff (Typ): 17V (Max)
• Voltage - Breakdown (Min): 19V
• Voltage - Clamping (Max) @ Ipp: 28V
• Current - Peak Pulse (10/1000µs): 1.4A
• Power - Peak Pulse: 40W
• Unidirectional Channels: 2
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• Type: Zener

The MMBZ20VALYT116 qualifies as a direct substitute based on identical electrical specifications and compatible packaging. The primary difference is the packaging format (Tape & Reel versus standard packaging) and supplier device package designation (SOT-23 versus SSD3), which do not affect electrical performance or circuit compatibility.

Engineering Selection Recommendations

Both the MMBZ20VALT116 and MMBZ20VALYT116 are active products manufactured by Rohm Semiconductor with identical electrical performance specifications. Selection between these parts should be based on:

• Packaging format requirements: The MMBZ20VALYT116 is supplied in Tape & Reel format, suitable for high-volume automated assembly processes. The MMBZ20VALT116 uses standard packaging appropriate for lower-volume or mixed-component applications.
• Supply chain availability: The MMBZ20VALYT116 has higher inventory availability (3,224 units) compared to the MMBZ20VALT116 (1,400 units).
• Regulatory compliance: Both parts meet ROHS3 compliance, REACH unaffected status, and carry identical moisture sensitivity ratings, ensuring equivalent environmental and regulatory performance.

Frequently Asked Questions (FAQ)

Q: Can MMBZ20VALYT116 be used as a direct replacement for MMBZ20VALT116 in existing designs?

A: Yes. Both parts are electrically identical with matching voltage ratings (17V reverse standoff, 28V clamping), current ratings (1.4A peak pulse), and power dissipation (40W). The SOT-23-3 package is mechanically compatible with the same PCB footprint.

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

A: The primary difference is packaging format. MMBZ20VALYT116 is supplied in Tape & Reel format for automated assembly, while MMBZ20VALT116 uses standard packaging. Electrical specifications and performance are identical.

Q: Are there any temperature or operating condition differences between these parts?

A: The MMBZ20VALYT116 specifies an operating temperature of 150°C (TJ). The MMBZ20VALT116 does not provide an explicit operating temperature specification in the available data. Both parts are rated for general-purpose applications.

Q: Do both parts have the same RoHS and REACH compliance status?

A: Yes. Both MMBZ20VALT116 and MMBZ20VALYT116 are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Which part should be selected for high-volume production?

A: MMBZ20VALYT116 in Tape & Reel format is optimized for high-volume automated assembly processes and offers greater inventory availability.
