• Voltage - Reverse Standoff (Typ): 30.8V
• Voltage - Breakdown (Min): 34.2V
• Voltage - Clamping (Max) @ Ipp: 49.9V
• Current - Peak Pulse (10/1000µs): 12A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Package / Case: DO-214AA, SMB
• Operating Temperature Range: -65°C ~ 150°C (TJ)
• Type: Zener
• Grade: Automotive
• Qualification: AEC-Q101

The P6SMB36AHM3_B/I is classified as a 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 P6SMB36AHM3_B/I is the manufacturer-recommended substitute for the obsolete P6SMB36AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical and mechanical specifications. The P6SMB36AHM3_B/I carries Active product status, ensuring continued availability and manufacturing support. Both parts meet AEC-Q101 automotive qualification requirements and ROHS3 compliance standards, making them suitable for automotive and telecom applications requiring transient voltage suppression.

The primary distinction between the two parts is packaging format: the substitute is supplied in Tape & Reel (TR) configuration, which is standard for high-volume production environments. This packaging difference does not affect electrical performance or mechanical compatibility in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the P6SMB36AHM3_B/I be used as a direct replacement for the P6SMB36AHM3_A/I?
