P6SMB16A-M3/5B Equivalent & Substitute Parts

Part Overview

The P6SMB16A-M3/5B is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates as a Zener-type TVS device in the P6SMB series, designated as TransZorb®. The part is actively produced and widely used in general-purpose transient voltage suppression applications. Finding equivalent and substitute parts is necessary to address supply chain variations, packaging preferences, and manufacturer availability while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB16A-M3/5B are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Breakdown (Min): 15.2V
• Voltage - Clamping (Max) @ Ipp: 22.5V
• Current - Peak Pulse (10/1000µs): 26.7A minimum
• Power - Peak Pulse: 600W
• Type: Zener
• Unidirectional Channels: 1

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB

Allowed Variations:

• Packaging format (Tape & Box vs. Tape & Reel)
• Manufacturer (same electrical specifications)
• Operating temperature range (within or exceeding specified range)
• RoHS compliance status (ROHS3 or equivalent)

Substitute parts maintain identical electrical performance and mechanical form factor, differing only in packaging delivery method and manufacturer source.

Parameter Comparison

Engineering Selection Recommendations

P6SMB16A-E3/5B (Vishay - Direct Manufacturer Substitute)

This part is a direct equivalent from the same manufacturer, differing only in packaging format (Tape & Reel instead of Tape & Box). All electrical specifications, operating temperature range, and compliance certifications are identical. Selection of this part is appropriate when Tape & Reel packaging is preferred for automated assembly processes.

P6SMB16A (Eaton - Manufacturer Recommended Substitute)

This part meets all critical electrical parameters with a marginally higher peak pulse current specification (27.1A vs. 26.7A), providing equivalent or superior performance. The operating temperature range is -55°C to 150°C, which covers the upper portion of the original specification. RoHS compliance is confirmed. This part is suitable for applications where the lower temperature limit of -55°C is acceptable. Eaton's P6SMB16A is actively produced with substantial inventory availability.

Both substitute parts maintain full electrical and mechanical compatibility with the P6SMB16A-M3/5B and are appropriate for direct replacement in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can P6SMB16A-E3/5B be used as a direct replacement for P6SMB16A-M3/5B?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications, operating temperature range, and compliance status. The only difference is packaging format: P6SMB16A-E3/5B uses Tape & Reel (TR) while P6SMB16A-M3/5B uses Tape & Box (TB). Selection depends on assembly process requirements.

Q: What is the difference between the Vishay and Eaton versions?

A: The Eaton P6SMB16A meets all critical electrical parameters with a peak pulse current of 27.1A (compared to 26.7A for Vishay). The operating temperature range is -55°C to 150°C versus -65°C to 150°C for Vishay. Both are RoHS compliant and suitable for general-purpose TVS applications.

Q: Is the lower operating temperature limit of -55°C (Eaton) a limitation?

A: The Eaton part operates from -55°C to 150°C. If your application requires operation below -55°C, the Vishay versions (P6SMB16A-M3/5B or P6SMB16A-E3/5B) with -65°C minimum temperature are required.

Q: Are all three parts in the same physical package?

A: Yes. All three parts use the DO-214AA (SMB) surface mount package, ensuring identical PCB footprint and mechanical compatibility.

Q: What does the packaging designation (TB vs. TR) mean?

A: TB (Tape & Box) indicates components supplied in tape format within a box, typically for smaller quantities. TR (Tape & Reel) indicates components on a continuous reel, optimized for high-volume automated assembly. Electrical performance is identical.

Q: Are all substitute parts RoHS compliant?

A: Yes. P6SMB16A-M3/5B and P6SMB16A-E3/5B are ROHS3 compliant. P6SMB16A (Eaton) is RoHS compliant. All meet environmental compliance requirements.
