Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMBJ130CAHM3_A/I is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage specifications must match exactly: 130V reverse standoff voltage, 144V minimum breakdown voltage, and 209V maximum clamping voltage. Current handling capability must remain at 2.9A peak pulse current (10/1000µs waveform). Power dissipation capacity must be maintained at 600W peak pulse. The component must retain bidirectional channel configuration (1 channel) and Zener diode type classification.

Mechanical compatibility requires identical package designation: DO-214AA (SMB) surface mount package. Operating temperature range must span -55°C to 150°C junction temperature. Automotive grade qualification (AEC-Q101) and ROHS3 compliance must be preserved.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ130CAHM3_B/I serves as the direct substitute for the obsolete SMBJ130CAHM3_A/I. Both components are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: SMBJ130CAHM3_A/I is classified as Obsolete, while SMBJ130CAHM3_B/I maintains Active status. Both components carry AEC-Q101 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are maintained in the substitution.

For new designs or component replenishment, SMBJ130CAHM3_B/I is the appropriate selection. Existing inventory of SMBJ130CAHM3_A/I may continue to be utilized in current production until depletion, as electrical and mechanical compatibility is complete.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130CAHM3_B/I be used as a direct replacement for SMBJ130CAHM3_A/I?

A: Yes. Both components are electrically and mechanically identical across all specified parameters. The SMBJ130CAHM3_B/I is the active production equivalent of the obsolete SMBJ130CAHM3_A/I.

Q: Are there any differences in package or pinout between these parts?

A: No. Both components use the DO-214AA (SMB) surface mount package with identical mechanical specifications and pinout configuration.

Q: What is the significance of the product status difference?

A: The SMBJ130CAHM3_A/I is classified as Obsolete, indicating it is no longer in active production. The SMBJ130CAHM3_B/I maintains Active status and represents the current production equivalent. For ongoing supply chain requirements, SMBJ130CAHM3_B/I should be specified.

Q: Do both parts meet the same automotive and compliance standards?

A: Yes. Both components carry AEC-Q101 automotive qualification, ROHS3 compliance, and REACH Unaffected status, ensuring equivalent regulatory and quality standing.

Q: Are the electrical performance characteristics identical?

A: Yes. Voltage ratings (130V standoff, 144V breakdown, 209V clamping), current handling (2.9A peak pulse), power dissipation (600W), and operating temperature range (-55°C to 150°C) are identical between both parts.
