Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB82CAHM3_A/I is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• 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
• Bidirectional Channels: 1
• Type: Zener

Mechanical Parameters (Must Match):

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

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The P6SMB82CAHM3_B/I meets all substitution criteria as a manufacturer-recommended equivalent with identical electrical and mechanical specifications. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB82CAHM3_B/I is the direct substitute for the obsolete P6SMB82CAHM3_A/I. Both components are manufactured by Vishay and maintain identical electrical and mechanical specifications. The substitute part carries active product status, ensuring continued availability and manufacturing support. Both parts maintain automotive-grade qualification under AEC-Q101 and ROHS3 compliance, meeting all regulatory requirements for telecom applications.

The primary operational difference is packaging configuration: the substitute is supplied in Tape & Reel format, which is standard for production environments. No circuit redesign or board layout modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB82CAHM3_B/I be used as a direct replacement for the P6SMB82CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical with matching voltage ratings (70.1V standoff, 113V clamping), current ratings (5.3A peak pulse), and power dissipation (600W). Both are qualified to AEC-Q101 and ROHS3 compliant. The substitute is the manufacturer-recommended equivalent.

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

A: The primary difference is product status and packaging. The P6SMB82CAHM3_A/I is obsolete and supplied in bulk packaging. The P6SMB82CAHM3_B/I is active and supplied in Tape & Reel format. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with the DO-214AA SMB package?

A: No. Both parts use the identical DO-214AA (SMB) surface mount package. PCB footprints, solder reflow profiles, and mounting procedures remain unchanged.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Packaging format does not affect electrical performance or reliability. Tape & Reel is a standard production format that provides improved handling and automated assembly compatibility.

Q: Are both parts suitable for automotive telecom applications?

A: Yes. Both parts carry automotive-grade qualification (AEC-Q101) and are specified for telecom applications. Operating temperature range is -65°C to 150°C for both.
