Key Parameters

Substitute Part Grouping Explanation

Substitution for the SMBJ130AHM3_A/I is determined by the following critical parameters:

• Voltage - Reverse Standoff: 130V (±5% tolerance)
• Voltage - Clamping (Max) @ Ipp: 209V
• Current - Peak Pulse (10/1000µs): 2.9A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA (SMB)
• Unidirectional configuration: 1 channel
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Automotive Grade with AEC-Q101 qualification

The SMBJ130AHM3_B/I meets all these electrical and mechanical requirements and is manufactured by the same supplier using the same base product platform (SMBJ130).

Parameter Comparison

Engineering Selection Recommendations

The SMBJ130AHM3_B/I is the direct substitute for the obsolete SMBJ130AHM3_A/I. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications, package configuration, and automotive qualifications. The primary distinction is product status: the SMBJ130AHM3_A/I is obsolete while the SMBJ130AHM3_B/I maintains active production status. The substitute part carries the same AEC-Q101 automotive qualification and ROHS3 compliance, ensuring compatibility in automotive and telecom applications. The packaging difference (tape & reel for the substitute versus unspecified for the main part) does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can SMBJ130AHM3_B/I be used as a direct replacement for SMBJ130AHM3_A/I?

A: Yes. Both parts are identical in electrical performance, voltage ratings, current handling, power dissipation, package type (DO-214AA/SMB), and automotive qualifications. The substitute is the recommended choice due to active production status.

Q: Are there differences in packaging between these parts?

A: The main part packaging is unspecified in available data. The substitute (SMBJ130AHM3_B/I) is supplied in Tape & Reel (TR) format. Both use the same DO-214AA (SMB) component package, ensuring PCB compatibility.

Q: Do both parts meet automotive standards?

A: Yes. Both the SMBJ130AHM3_A/I and SMBJ130AHM3_B/I are automotive grade components with AEC-Q101 qualification, suitable for automotive and telecom applications.

Q: What are the critical voltage parameters for substitution?

A: The critical parameters are: Reverse Standoff Voltage of 130V, Breakdown Voltage minimum of 144V, and Clamping Voltage maximum of 209V at peak pulse current. Both parts match these specifications exactly.

Q: Is the SMBJ130AHM3_B/I compliant with environmental regulations?

A: Yes. The substitute part is ROHS3 compliant and REACH unaffected, matching the compliance status of the original part.
