Engineering Selection Recommendations

Selection among the listed substitute Zener diodes should consider the product status and RoHS compliance. The 1N5367A/TR8 device is listed as RoHS non-compliant, while all listed substitutes are ROHS3 compliant and active. Where RoHS compliance is mandated, 1N5367BG, 1N5367BRLG, 1N5260B-TAP, and BZX79-C43,133 are suitable alternatives.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for selecting a substitute for the 1N5367A/TR8 Zener diode?
A1: Substitutes are selected based on matching voltage rating, tolerance, power dissipation, impedance, leakage current, forward voltage, operating temperature range, mounting type, and package/case type.

Q2: Are the substitute parts pin-to-pin compatible with the 1N5367A/TR8?
A2: All listed substitutes use a through-hole axial package, consistent with the original part's mounting requirements.

Q3: How does RoHS compliance affect substitution?
A3: The original part is RoHS non-compliant. If compliance is necessary, select a substitute marked as ROHS3 compliant.

Q4: Can alternative packages be used as direct substitutes?
A4: Only through-hole axial package types with matching key dimensions are listed, ensuring mechanical compatibility.

Q5: Are all listed substitutes currently active products?
A5: Yes, all substitutes listed are active and suitable for ongoing design use within the specified parameters.
