Substitute Part Grouping Explanation

Substitution for the SMBJ150AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 150V (±5% tolerance)
• Voltage - Breakdown (Min): 167V
• Voltage - Clamping (Max) @ Ipp: 243V
• Current - Peak Pulse (10/1000µs): 2.5A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade: AEC-Q101 Qualified
• RoHS Status: ROHS3 Compliant

The SMBJ150AHM3_B/I meets all these criteria and is the manufacturer-recommended substitute. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.

Parameter Comparison

Engineering Selection Recommendations
