Substitute Part Grouping Explanation

Substitution of the P6SMB200CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 171V (Typ)
• Voltage - Breakdown: 190V (Min)
• Voltage - Clamping: 274V (Max) @ Ipp
• Current - Peak Pulse: 2.2A (10/1000µs)
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1
• Operating Temperature: -65°C to 150°C (TJ)
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB200CAHM3_B/I is identified as a manufacturer-recommended substitute. Both parts share identical electrical specifications, thermal operating range, package configuration, and automotive-grade qualification. The primary distinction is product status: the substitute part is Active, whereas the original part is Obsolete.
