Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ60CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 60V
• Voltage - Breakdown (Min): 66.7V
• Voltage - Clamping (Max) @ Ipp: 96.8V
• Current - Peak Pulse (10/1000µs): 6.2A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The SMBJ60CAHM3_B/I is classified as a manufacturer-recommended substitute. Both parts share identical electrical specifications and thermal performance characteristics. The primary distinction is product status: the SMBJ60CAHM3_A/I is obsolete, while the SMBJ60CAHM3_B/I maintains active production status.

Parameter Comparison
