Substitute Part Grouping Explanation

Substitution for the SMBJ5.0AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5V
• Voltage - Breakdown (Min): 6.4V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 65.2A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101

The SMBJ5.0AHM3_B/I is identified as the manufacturer-recommended substitute. This part maintains identical electrical specifications and mechanical packaging while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ5.0AHM3_B/I is the direct equivalent substitute for the obsolete SMBJ5.0AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical performance specifications across all critical parameters: 5V reverse standoff voltage, 9.2V clamping voltage, and 65.2A peak pulse current.
