Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ10CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 10V (±tolerance)
• Voltage - Breakdown (Min): 11.1V
• Voltage - Clamping (Max) @ Ipp: 17V
• Current - Peak Pulse (10/1000µs): 35.3A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Type: Zener
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The SMBJ10CAHM3_B/I is the manufacturer-recommended substitute, maintaining identical electrical specifications and compliance certifications while differing only in product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ10CAHM3_B/I is the direct substitute for the obsolete SMBJ10CAHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical performance specifications, thermal operating range, and automotive-grade AEC-Q101 qualification. Both parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction is product status: SMBJ10CAHM3_A/I is obsolete while SMBJ10CAHM3_B/I is active. For new designs or ongoing production requiring this 10V TVS diode with 600W peak pulse power rating, SMBJ10CAHM3_B/I ensures continued availability and manufacturer support. The packaging difference (Tape & Reel for the substitute) is a standard industry format for active production components and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMBJ10CAHM3_B/I be used as a direct replacement for SMBJ10CAHM3_A/I?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage ratings (10V standoff, 17V clamping), current handling (35.3A peak pulse), power dissipation (600W), operating temperature range (-55°C to 150°C), and package format (DO-214AA SMB). Both are AEC-Q101 qualified and RoHS3 compliant.

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

A: The primary difference is product status. SMBJ10CAHM3_A/I is obsolete, while SMBJ10CAHM3_B/I is active. The substitute also specifies Tape & Reel packaging, which is standard for active production components. Electrical specifications and performance are identical.

Q: Are there any compatibility concerns when switching from SMBJ10CAHM3_A/I to SMBJ10CAHM3_B/I?

A: No compatibility concerns exist. Both parts use the same DO-214AA (SMB) surface mount package, have identical pinout, and meet the same electrical and thermal specifications. PCB layout and circuit design require no modification.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel is a standard packaging and handling format for surface mount components. It does not affect electrical performance, reliability, or thermal characteristics. The component itself remains identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both SMBJ10CAHM3_A/I and SMBJ10CAHM3_B/I carry automotive-grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: What compliance certifications do these parts hold?

A: Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both meet HTSUS code 8541.10.0080 for semiconductor diodes.
