Substitute Part Grouping Explanation

Substitute parts for TVS diode SMAJ75A-E3/5A are grouped strictly by matching essential electrical and mechanical parameters:

• Unidirectional TVS diode operation
• Standoff voltage (75V typ.)
• Breakdown voltage (83.3V min.)
• Clamping voltage (121V max. @ 3.3A)
• Peak pulse current (3.3A)
• Peak pulse power (400W)
• Surface mount DO-214AC (SMA) package
• General purpose application suitability
• RoHS3 compliance
• Comparable operating temperature range

Only parts that precisely match these listed parameters are designated as substitutes.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute transient voltage suppressor TVS diodes are active, RoHS3 compliant, and share the same Moisture Sensitivity Level (MSL 1), ECCN, and HTSUS classifications as the original SMAJ75A-E3/5A. The operating temperature ranges are compatible within specified limits. Selection is suitable for inventory maintenance and design changes requiring matched electrical and mechanical characteristics with compliance to the stated standards.

Frequently Asked Questions (FAQ)

Q1: What determines if a substitute TVS diode is compatible with SMAJ75A-E3/5A?
A1: Compatibility is strictly based on matching standoff, breakdown, and clamping voltages, peak pulse current, peak pulse power, package type (DO-214AC SMA), and unidirectional operation.

Q2: Is the footprint and mounting identical across all substitutes listed?
A2: All substitutes use the DO-214AC (SMA) package and are designed for surface mount applications.

Q3: Are there any regulatory or compliance differences among the listed equivalents?
A3: All substitutes are RoHS3 compliant and have MSL 1 classification. ECCN and HTSUS codes are identical.

Q4: Is the operating temperature range always the same?
A4: Substitute parts offer operating temperature ranges fully covered by the original device range. For instance, SMAJ75A-TP supports an extended upper temperature up to 175°C (TA).

Q5: Do all substitutes perform equally in general purpose applications?
A5: All substitutes are specified for general purpose, with identical electrical ratings and package type.

Q6: Are there any form, fit, or function discrepancies?
A6: No discrepancies exist with respect to form, fit, or function based on the provided parameters.

Q7: How is substitution approved for engineering release?
A7: Substitution is determined by matching all listed key electrical, mechanical, and compliance parameters without deviation from the specification set.

Q8: Can these substitutes be used interchangeably in automated SMT processes?
A8: All listed substitutes use the surface mount DO-214AC (SMA) package suitable for automated SMT assembly processes.
