Substitute Part Grouping Explanation

Substitution for the P6SMB10AHM3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 8.55V
• Voltage - Breakdown (Min): 9.5V
• Voltage - Clamping (Max) @ Ipp: 14.5V
• Current - Peak Pulse (10/1000µs): 41.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Type: Zener, Unidirectional
• Automotive Grade: AEC-Q101 Qualified
• RoHS Compliance: ROHS3 Compliant

The P6SMB10AHM3_B/I is classified as a direct manufacturer-recommended substitute, maintaining identical electrical specifications and package configuration while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB10AHM3_B/I is the manufacturer-recommended substitute for the obsolete P6SMB10AHM3_A/I. Both components are qualified to AEC-Q101 automotive standards and maintain ROHS3 compliance. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary distinction between the two parts is packaging format: the substitute is supplied in Tape & Reel (TR) configuration, which is standard for high-volume manufacturing and automated assembly processes. Electrical performance, thermal characteristics, and mechanical compatibility remain identical across both part numbers.

Selection of the P6SMB10AHM3_B/I is appropriate for all applications previously specified for the P6SMB10AHM3_A/I, provided that the Tape & Reel packaging format is compatible with your procurement and assembly workflow.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB10AHM3_B/I be used as a direct replacement for the P6SMB10AHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (8.55V standoff, 14.5V clamping), current handling (41.4A peak pulse), power dissipation (600W), and package configuration (DO-214AA SMB). The substitute is the manufacturer-recommended alternative.

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

A: The primary difference is product status and packaging format. The P6SMB10AHM3_A/I is obsolete and supplied in standard packaging, while the P6SMB10AHM3_B/I is active production and supplied in Tape & Reel format. All electrical and thermal specifications are identical.

Q: Are both parts automotive-qualified?

A: Yes. Both the P6SMB10AHM3_A/I and P6SMB10AHM3_B/I are AEC-Q101 qualified and suitable for automotive applications requiring transient voltage suppression in the 10V class.

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

A: No. Tape & Reel is a packaging and delivery format only. It does not affect electrical performance, thermal characteristics, or reliability of the component itself.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What applications are these TVS diodes suitable for?

A: These components are specified for telecom applications requiring transient voltage suppression. The unidirectional configuration and 10V rating make them suitable for protecting sensitive circuitry from voltage transients within this specification range.
