Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB160CAHM3_A/I is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 136V
• Voltage - Breakdown (Min): 152V
• Voltage - Clamping (Max) @ Ipp: 219V
• Current - Peak Pulse (10/1000µs): 2.7A
• Power - Peak Pulse: 600W
• Bidirectional Channels: 1

Mechanical Parameters (Must Match):

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

Compliance & Certification (Must Match):

• Manufacturer: Vishay General Semiconductor - Diodes Division
• Series: P6SMB, TransZorb®
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The substitute part P6SMB160CAHM3_B/I meets all electrical, mechanical, and compliance requirements for direct substitution. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P6SMB160CAHM3_B/I is the direct equivalent substitute for the P6SMB160CAHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division within the P6SMB TransZorb® series and share identical electrical specifications, thermal operating range, and automotive-grade certifications including AEC-Q101 qualification.

The primary advantage of selecting P6SMB160CAHM3_B/I is its Active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance and are suitable for telecom transient voltage suppression applications.

The packaging difference (Tape & Reel versus bulk) does not affect electrical performance or functional compatibility. Selection between these formats depends on production volume requirements and assembly process specifications.

Frequently Asked Questions (FAQ)

Q: Can P6SMB160CAHM3_B/I be used as a direct replacement for P6SMB160CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical. They share the same 136V reverse standoff voltage, 219V clamping voltage, 2.7A peak pulse current, and 600W power dissipation. Both are housed in DO-214AA (SMB) surface mount packages and carry identical automotive-grade certifications.

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

A: The primary differences are product status and packaging format. P6SMB160CAHM3_A/I is Obsolete with bulk packaging, while P6SMB160CAHM3_B/I is Active with Tape & Reel packaging. Electrical performance and specifications are identical.

Q: Are there any compatibility concerns when substituting P6SMB160CAHM3_B/I for P6SMB160CAHM3_A/I?

A: No compatibility concerns exist. Both parts use identical DO-214AA (SMB) surface mount packages, operate across the same temperature range (-65°C to 150°C), and meet the same automotive and RoHS compliance standards. PCB footprints and assembly processes remain unchanged.

Q: Does the Tape & Reel packaging of P6SMB160CAHM3_B/I affect circuit performance?

A: No. Packaging format does not affect electrical performance or functional characteristics. Tape & Reel packaging is a supply and assembly convenience format. The component itself performs identically to bulk-packaged versions.

Q: Why is P6SMB160CAHM3_A/I marked as Obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. P6SMB160CAHM3_B/I, as an Active equivalent, provides continued availability and support for applications requiring 160V bidirectional TVS diodes in the P6SMB series.

Q: Are both parts suitable for automotive applications?

A: Yes. Both P6SMB160CAHM3_A/I and P6SMB160CAHM3_B/I carry Automotive grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.
