Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ160CAHM3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 160V
• Voltage - Breakdown (Min): 178V
• Voltage - Clamping (Max) @ Ipp: 259V
• Current - Peak Pulse (10/1000µs): 2.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade and AEC-Q101 Qualification

The SMBJ160CAHM3_B/I is the direct active equivalent, maintaining identical electrical specifications and automotive qualifications while differing only in packaging format (Tape & Reel) and product status (Active).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ160CAHM3_B/I is the direct replacement for the obsolete SMBJ160CAHM3_A/I. Both components maintain identical electrical performance specifications and automotive qualifications (AEC-Q101). The primary distinction is product status: the _B/I variant is currently active in production, while the _A/I is obsolete. Both components are ROHS3 compliant and suitable for telecom transient protection applications. Selection of the SMBJ160CAHM3_B/I ensures continued access to qualified inventory and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the SMBJ160CAHM3_B/I be used as a direct replacement for the SMBJ160CAHM3_A/I?

A: Yes. Both components are electrically and mechanically identical across all critical parameters: 160V reverse standoff voltage, 259V clamping voltage, 2.3A peak pulse current, 600W peak pulse power, and DO-214AA (SMB) package. Both maintain AEC-Q101 automotive qualification and ROHS3 compliance.

Q: What is the difference between the _A/I and _B/I variants?

A: The primary differences are product status and packaging format. The _A/I is obsolete, while the _B/I is active. The _B/I is supplied in Tape & Reel (TR) format, whereas the _A/I uses standard packaging. Electrical specifications and performance are identical.

Q: Are there any compatibility concerns when switching from SMBJ160CAHM3_A/I to SMBJ160CAHM3_B/I?

A: No compatibility concerns exist. The components are pin-compatible, electrically equivalent, and both qualified to the same automotive standards. PCB layout and circuit design require no modification.

Q: What applications are these components suitable for?

A: Both components are designed for telecom applications requiring transient voltage suppression. The bidirectional configuration and automotive-grade qualification make them suitable for protection circuits in telecommunications equipment operating across the -55°C to 150°C temperature range.

Q: Are both components RoHS compliant?

A: Yes. Both the SMBJ160CAHM3_A/I and SMBJ160CAHM3_B/I are ROHS3 compliant and REACH unaffected.
