Substitute Part Grouping Explanation

Substitution eligibility for the SM6T24AHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 20.5V
• Voltage - Breakdown (Min): 22.8V
• Voltage - Clamping (Max) @ Ipp: 33.2V
• Current - Peak Pulse (10/1000µs): 18A
• Power - Peak Pulse: 600W
• Type: Zener, Unidirectional
• Package / Case: DO-214AA (SMB)
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade with AEC-Q101 Qualification
• RoHS3 Compliance

The SM6T24AHM3_B/I meets all substitution criteria as a direct equivalent, sharing identical electrical specifications, package configuration, and automotive qualification requirements. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SM6T24AHM3_B/I is the direct substitute for the obsolete SM6T24AHM3_A/I. Both components are manufactured by Vishay General Semiconductor - Diodes Division within the SM6T TransZorb® series and maintain identical electrical performance specifications across all critical parameters.

The SM6T24AHM3_B/I carries Active product status, ensuring ongoing availability and manufacturing support. Both parts meet automotive-grade requirements with AEC-Q101 qualification and ROHS3 compliance, making them suitable for equivalent circuit implementations without design modification.

The primary operational difference is packaging format: the SM6T24AHM3_A/I is supplied in bulk format, while the SM6T24AHM3_B/I is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical performance or functional compatibility.
