Substitution of the P6SMB56AHM3_A/I is determined by the following critical electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 47.8V
• Voltage - Breakdown (Min): 53.2V
• Voltage - Clamping (Max) @ Ipp: 77V
• Current - Peak Pulse (10/1000µs): 7.8A
• Power - Peak Pulse: 600W
• Unidirectional Channels: 1
• Type: Zener

Mechanical Parameters (Must Match):

• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The substitute part P6SMB56AHM3_B/I maintains identical electrical specifications and mechanical packaging while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The P6SMB56AHM3_B/I is the direct equivalent for the obsolete P6SMB56AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, mechanical packaging, and automotive-grade certifications including AEC-Q101 qualification and ROHS3 compliance.

The primary distinction is product status: P6SMB56AHM3_A/I is obsolete while P6SMB56AHM3_B/I maintains active status. The substitute part is available in Tape & Reel packaging, which is standard for production environments. Both parts are suitable for telecom applications requiring 600W peak pulse power dissipation and transient voltage suppression at 47.8V standoff voltage.

Frequently Asked Questions (FAQ)

Q: Can P6SMB56AHM3_B/I be used as a direct replacement for P6SMB56AHM3_A/I?

A: Yes. Both parts are identical in electrical performance, mechanical packaging (DO-214AA SMB), and automotive qualification (AEC-Q101). The substitute part is active and available, making it the appropriate choice for new designs and ongoing production.

Q: What is the difference between the A/I and B/I variants?

A: The primary difference is product lifecycle status. P6SMB56AHM3_A/I is obsolete, while P6SMB56AHM3_B/I is active. Electrical specifications and mechanical packaging are identical. Packaging format differs: A/I is supplied in bulk, while B/I is supplied in Tape & Reel.

Q: Are there any compatibility concerns when switching from P6SMB56AHM3_A/I to P6SMB56AHM3_B/I?

A: No compatibility concerns exist. Both parts use the same DO-214AA SMB surface mount package, operate across the same temperature range (-65°C to 150°C), and meet identical automotive and RoHS compliance requirements.

Q: What are the critical parameters that define substitution for this TVS diode?

A: Substitution is determined by matching voltage ratings (47.8V standoff, 53.2V breakdown minimum, 77V clamping maximum), current rating (7.8A peak pulse), power rating (600W), package type (DO-214AA SMB), and automotive qualifications (AEC-Q101, ROHS3 Compliant).

Q: Is the Tape & Reel packaging of P6SMB56AHM3_B/I suitable for my application?

A: Tape & Reel packaging is standard for surface mount production environments and is compatible with automated assembly equipment. The component itself is identical to bulk-packaged versions; only the delivery format differs.
