Substitute Part Grouping Explanation

Substitution of the P6SMB24AHM3_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): 18.1A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Unidirectional Channels: 1
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Automotive Grade: AEC-Q101 Qualified
• RoHS Status: ROHS3 Compliant

The P6SMB24AHM3_B/I is classified as a manufacturer-recommended substitute. This part maintains identical electrical specifications and thermal performance while differing only in packaging configuration (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB24AHM3_B/I is the direct equivalent substitute for the obsolete P6SMB24AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical and thermal characteristics. The substitute part carries Active product status, ensuring continued availability and manufacturing support.

Both parts satisfy automotive-grade requirements with AEC-Q101 qualification and ROHS3 compliance. The primary distinction is packaging configuration: the substitute is supplied in Tape & Reel format, which is standard for high-volume production environments. No electrical performance degradation or functional compromise occurs with this substitution.

Frequently Asked Questions (FAQ)

Q: Can P6SMB24AHM3_B/I be used as a direct replacement for P6SMB24AHM3_A/I?

A: Yes. Both parts are electrically and thermally identical with matching voltage ratings (20.5V standoff, 33.2V clamping), current specifications (18.1A peak pulse), and power dissipation (600W). Both are housed in DO-214AA (SMB) surface mount packages and qualified to AEC-Q101 automotive standards.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging configuration. The P6SMB24AHM3_A/I is supplied in bulk packaging, while the P6SMB24AHM3_B/I is supplied in Tape & Reel (TR) format. Additionally, the substitute part maintains Active product status, whereas the original is classified as Obsolete.
