Substitute Part Grouping Explanation

Substitution of the P6SMB160AHE3_A/H is determined by strict electrical and mechanical parameter matching within the P6SMB series. The following parameters establish substitution validity:

• Voltage - Reverse Standoff (Typ): 136V
• Voltage - Breakdown (Min): 152V
• Voltage - Clamping (Max) @ Ipp: 219V
• Current - Peak Pulse (10/1000µs): 2.7A
• Power - Peak Pulse: 600W
• Operating Temperature Range: -65°C to 150°C (TJ)
• Package / Case: DO-214AA, SMB
• Unidirectional Channels: 1
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB160AHE3_B/H is identified as the manufacturer-recommended substitute. Both parts share identical electrical specifications and mechanical packaging, with the primary distinction being product status: the substitute is active production while the original is obsolete.
