Engineering Selection Recommendations

Selection among substitute Zener diodes is governed by electrical parameter equivalence, package compatibility, and environmental compliance. All listed substitutes are ROHS3 compliant, have a Moisture Sensitivity Level of 1 (Unlimited), and are REACH unaffected. Obsolete status of PZM13NB,115 necessitates transition to currently active substitutes meeting these requirements.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match when substituting a Zener diode for PZM13NB,115?
A: The substitute must have a 13 V nominal Zener voltage, equivalent tolerance, maximum power rating close to 300 mW, similar operating temperature range, and comparable reverse leakage and impedance values.

Q: Are the listed substitute Zener diodes compatible with the same mounting method and case as PZM13NB,115?
A: Yes. All substitutes provided are surface mount devices compatible with TO-236-3, SC-59, and SOT-23-3 package types.

Q: What compliance certifications are matched by the substitutes?
A: All substitute parts are ROHS3 compliant, have a Moisture Sensitivity Level of 1 (Unlimited), and are REACH unaffected.

Q: How does package type affect direct replacement?
A: Direct replacement is facilitated by identical or compatible footprint and package/case dimensions (TO-236-3, SC-59, SOT-23-3).

Q: If the PZM13NB,115 is obsolete, can any listed substitute be used in its place?
A: Yes, provided the key electrical parameters and package compatibility match as presented in the table, substitution is appropriate under the given information.
