Substitute Part Grouping Explanation

Substitution of the P6SMB82CA-M3/52 is determined by strict equivalence of the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 70.1V
• Voltage - Breakdown (Min): 77.9V
• Voltage - Clamping (Max) @ Ipp: 113V
• Current - Peak Pulse (10/1000µs): 5.3A
• Power - Peak Pulse: 600W
• Mounting Type: Surface Mount
• Package / Case: DO-214AA, SMB
• Operating Temperature: -65°C ~ 150°C (TJ)
• Type: Zener, Bidirectional

The primary substitute identified is P6SMB82CA-E3/52, which maintains identical electrical specifications and mechanical compatibility. The difference between the main part and its substitute is limited to packaging configuration: the main part uses Tape & Box (TB) packaging, while the substitute uses Tape & Reel (TR) packaging. Both parts share the same base product number (P6SMB82) and are manufactured by the same supplier.

Parameter Comparison

Engineering Selection Recommendations

Both P6SMB82CA-M3/52 and P6SMB82CA-E3/52 are active production parts with identical electrical and thermal specifications. Selection between these parts should be based on packaging requirements and supply chain logistics:

• P6SMB82CA-M3/52 (Tape & Box): Suitable for applications requiring smaller order quantities or mixed component shipments.
• P6SMB82CA-E3/52 (Tape & Reel): Suitable for high-volume manufacturing environments utilizing automated pick-and-place assembly equipment.

Both parts maintain full ROHS3 compliance and carry unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly processes. No additional testing or qualification is required when substituting between these two part numbers, provided the packaging format is compatible with the intended assembly method.

Frequently Asked Questions (FAQ)

Q: Can P6SMB82CA-E3/52 be used as a direct replacement for P6SMB82CA-M3/52?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Box versus Tape & Reel. Substitution is valid provided the receiving assembly process can accommodate the alternate packaging configuration.

Q: What does the packaging designation (M3 vs. E3) indicate?

A: The designations M3 and E3 refer to the packaging and supplier configuration codes assigned by Vishay. M3 indicates Tape & Box packaging, while E3 indicates Tape & Reel packaging. Both use the same DO-214AA (SMB) component package.

Q: Are there any electrical performance differences between these substitute parts?

A: No. Both parts share identical electrical specifications: 70.1V reverse standoff voltage, 77.9V minimum breakdown voltage, 113V maximum clamping voltage, and 5.3A peak pulse current. Operating temperature range and power dissipation ratings are also identical.

Q: What is the operating temperature range for this TVS diode?

A: The operating temperature range is -65°C to 150°C (junction temperature). This specification applies to both the main part and its substitute.

Q: Is this component RoHS compliant?

A: Yes. Both P6SMB82CA-M3/52 and P6SMB82CA-E3/52 are ROHS3 compliant and carry REACH Unaffected status.

Q: What is the moisture sensitivity level (MSL) for this component?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard PCB assembly processes and storage conditions are acceptable.
