Key Parameters

Substitute Part Grouping Explanation

Substitute parts for Transient Voltage Suppressor (TVS) diodes are determined by exact alignment of electrical, mechanical, and compliance-related parameters. The substitute must share the following key parameters: reverse standoff voltage (Typ), breakdown voltage (Min), clamping voltage (Max) at specified peak pulse current, peak pulse power, mounting type, package/case, automotive grade, AEC-Q101 qualification, operating temperature range, and RoHS/REACH compliance status. Only parts explicitly matching these characteristics within the same product family or series are considered as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

SMB10J22AHM3_B/I is active and meets all critical compliance certifications, including ROHS3 and AEC-Q101, matching the automotive grade and operating temperature range specified in SMB10J22AHM3_A/I. Selection between these models is determined by part status, with SMB10J22AHM3_B/I as the suitable substitute for applications requiring continued availability and compliance within the specified parameters.

Frequently Asked Questions (FAQ)

Q1: What determines substitution compatibility for TVS diodes in this case?
A1: Compatibility is determined strictly by matching reverse standoff voltage, breakdown voltage, clamping voltage at peak pulse current, peak pulse power, automotive grade, AEC-Q101 qualification, operating temperature range, mounting type, and package/case.

Q2: Is the substitute part SMB10J22AHM3_B/I mechanically identical to the main part?
A2: Both parts use the DO-214AA (SMB) surface mount package and share supplier device package identification, ensuring mechanical interchangeability.

Q3: Are compliance and environmental standards matched between the main and substitute part?
A3: Both parts are ROHS3 Compliant and REACH Unaffected, with AEC-Q101 automotive qualification.

Q4: Does the substitute part support the same electrical protection?
A4: All specified electrical parameters, including voltage, current, and peak pulse power ratings, are identical between SMB10J22AHM3_A/I and SMB10J22AHM3_B/I.

Q5: How should inventory status influence component selection?
A5: SMB10J22AHM3_A/I is Obsolete, so selection should prioritize SMB10J22AHM3_B/I, which is classified as Active and available in stock.
