Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB170CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 145V
• Voltage - Breakdown (Min): 162V
• Voltage - Clamping (Max) @ Ipp: 234V
• Current - Peak Pulse (10/1000µs): 2.6A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Type: Zener
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The P6SMB170CAHM3_B/I is identified as the manufacturer-recommended substitute. Both parts share identical electrical specifications, thermal characteristics, and package configuration. The primary distinction is product status: the original part is Obsolete, while the substitute is Active. The substitute maintains full compliance with RoHS3, REACH, and automotive qualification requirements.

Parameter Comparison

Engineering Selection Recommendations
