SMBJ58CAHM3_A/I Equivalent & Substitute Parts

Part Overview

The SMBJ58CAHM3_A/I is a bidirectional transient voltage suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for telecom applications requiring transient protection. This component operates with a 58V reverse standoff voltage and provides 93.6V maximum clamping voltage at peak pulse current of 6.4A, delivering 600W peak pulse power dissipation in a surface mount DO-214AA (SMB) package.

The SMBJ58CAHM3_A/I carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring this specific electrical and mechanical configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ58CAHM3_A/I is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 58V (±5% tolerance)
• Voltage - Clamping (Max) @ Ipp: 93.6V
• Current - Peak Pulse: 6.4A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Bidirectional configuration: 1 channel
• Operating Temperature Range: -55°C to 150°C (TJ)
• Automotive Grade with AEC-Q101 qualification
• RoHS3 compliance

The SMBJ58CAHM3_B/I meets all these criteria and qualifies as a direct substitute. The primary distinction is packaging format and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ58CAHM3_B/I is the direct substitute for SMBJ58CAHM3_A/I. Both components maintain identical electrical specifications, automotive-grade qualification, and AEC-Q101 certification. The transition from obsolete to active product status makes SMBJ58CAHM3_B/I the preferred selection for new designs and ongoing production requirements.

The packaging format difference (bulk versus Tape & Reel) reflects standard industry practice for active versus legacy product lines and does not affect electrical performance or mechanical compatibility in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can SMBJ58CAHM3_B/I be used as a direct replacement for SMBJ58CAHM3_A/I?

A: Yes. Both parts share identical electrical parameters, including reverse standoff voltage, clamping voltage, peak pulse current, and power dissipation. Both are packaged in DO-214AA (SMB) and meet automotive AEC-Q101 qualification requirements.

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

A: The primary difference is product status and packaging format. SMBJ58CAHM3_A/I is obsolete and supplied in bulk packaging, while SMBJ58CAHM3_B/I is active and supplied in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both components use the same DO-214AA (SMB) surface mount package with identical footprint and soldering requirements. PCB designs do not require modification.

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

A: No. Tape & Reel packaging is a standard format for active production components and does not impact electrical performance, reliability, or operating characteristics.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SMBJ58CAHM3_A/I and SMBJ58CAHM3_B/I are ROHS3 compliant and REACH unaffected.
