Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6SMB110A-M3/52 are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 94V
• Voltage - Breakdown (Min): 105V
• Voltage - Clamping (Max) @ Ipp: 152V
• Package / Case: DO-214AA, SMB (surface mount)
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener

All identified substitutes maintain these core specifications, ensuring functional equivalence in transient voltage suppression applications. Variations in peak pulse current (3.9A vs. 4A) and packaging format (Tape & Box vs. Tape & Reel) do not affect electrical compatibility but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet applicable compliance requirements (RoHS and REACH standards). Selection between these substitutes should be based on:

• Packaging Format Requirements: The P6SMB110A-M3/52 is supplied in Tape & Box format, while P6SMB110A-E3/52 is available in Cut Tape & Digi-Reel format, and P6SMB110A is supplied in standard Tape & Reel format. Choose based on assembly line compatibility and procurement volume requirements.

• Temperature Range Specification: The P6SMB110A-M3/52 and P6SMB110A-E3/52 both support the extended lower temperature limit of -65°C, while the Eaton P6SMB110A supports -55°C minimum. For applications requiring operation below -55°C, the Vishay variants are required.

• Peak Pulse Current: The Eaton P6SMB110A provides 4A peak pulse current compared to 3.9A for the Vishay variants. This represents a minor increase in transient handling capability with identical clamping voltage performance.

• Manufacturer Source Diversity: Selecting the Eaton P6SMB110A provides alternative sourcing from a different manufacturer while maintaining electrical equivalence, supporting supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can P6SMB110A-E3/52 be used as a direct replacement for P6SMB110A-M3/52?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications (94V standoff, 105V breakdown minimum, 152V clamping maximum, 3.9A peak pulse current, 600W peak power). The difference is packaging format: Tape & Box versus Cut Tape & Digi-Reel. Electrical performance in the circuit is equivalent.

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

A: The primary electrical difference is peak pulse current: Eaton P6SMB110A provides 4A versus 3.9A for Vishay parts. All other electrical parameters (voltage ratings, clamping, power dissipation) are identical. The Eaton part has a minimum operating temperature of -55°C versus -65°C for Vishay variants. Packaging format also differs.

Q: Are all three parts suitable for the same application?

A: Yes, provided the application does not require operation below -55°C. All three parts maintain the same voltage suppression characteristics (94V standoff, 152V clamping) and power handling (600W peak). The Eaton variant's slightly higher peak pulse current (4A) provides additional margin in transient protection.

Q: Does packaging format affect electrical performance?

A: No. Tape & Box, Cut Tape & Digi-Reel, and standard Tape & Reel are packaging and delivery formats only. They do not affect the electrical characteristics of the diode itself. Selection should be based on assembly equipment compatibility and procurement volume requirements.

Q: Are all parts RoHS compliant?

A: Yes. P6SMB110A-M3/52 and P6SMB110A-E3/52 are ROHS3 Compliant. P6SMB110A (Eaton) is RoHS Compliant. Both certifications meet current regulatory requirements for electronic components.
