P6SMB62CAHM3_A/I Equivalent & Substitute Parts

Part Overview

The P6SMB62CAHM3_A/I is a bidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for telecom applications requiring transient overvoltage protection in surface mount configurations. The part operates with a 53V reverse standoff voltage and provides 85V maximum clamping voltage at peak pulse current of 7.1A, delivering 600W peak pulse power dissipation.

The P6SMB62CAHM3_A/I is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution of the P6SMB62CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 53V
• Voltage - Breakdown (Min): 58.9V
• Voltage - Clamping (Max) @ Ipp: 85V
• Current - Peak Pulse (10/1000µs): 7.1A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB62CAHM3_B/I is a direct substitute manufactured by the same supplier within the same P6SMB TransZorb® series. Both parts share identical electrical specifications and mechanical packaging. The primary distinction is product status: the _A/I variant is obsolete, while the _B/I variant maintains active production status with improved availability.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB62CAHM3_B/I is the direct equivalent substitute for the obsolete P6SMB62CAHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical and thermal performance specifications. The _B/I variant carries active product status, ensuring long-term availability and supply chain continuity.

Both parts satisfy automotive-grade requirements with AEC-Q101 qualification and ROHS3 compliance. The _B/I variant is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly processes. The _A/I variant was supplied in bulk packaging and is no longer in production.

For new designs and production runs, the P6SMB62CAHM3_B/I is the appropriate selection. For field replacements or legacy system maintenance, the _B/I variant provides functional and electrical equivalence with improved component availability.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB62CAHM3_B/I be used as a direct replacement for the P6SMB62CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical. All voltage ratings, current specifications, temperature ranges, and automotive qualifications match exactly. The primary difference is product status and packaging format.

Q: What is the difference between the _A/I and _B/I designations?

A: The suffix designations indicate production variants within the same part family. The _A/I is obsolete, while the _B/I maintains active production status. The electrical and mechanical specifications are identical.

Q: Is the Tape & Reel (TR) packaging of the _B/I variant compatible with existing assembly equipment?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your assembly process currently uses bulk packaging, conversion to Tape & Reel format is a standard industry practice and does not affect component performance or compatibility.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the P6SMB62CAHM3_A/I and P6SMB62CAHM3_B/I carry automotive-grade classification with AEC-Q101 qualification. Both are ROHS3 compliant and suitable for automotive telecom protection circuits.

Q: What is the moisture sensitivity level (MSL) for the _B/I variant?

A: The P6SMB62CAHM3_B/I maintains MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
