Key Parameters

Substitute Part Grouping Explanation

Substitution logic for Zener diodes in this category requires strict alignment to the following parameters: Voltage - Zener (Nom) (Vz), Tolerance, Power - Max, Impedance (Max) (Zzt), Current - Reverse Leakage @ Vr, Voltage - Forward (Vf) (Max) @ If, Operating Temperature, Mounting Type, Package / Case, and Supplier Device Package. Additionally, compliance to RoHS status and moisture sensitivity levels must match application requirements. Only substitute models matching these key criteria qualify as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Selection between SMBJ5919A/TR13 and SMBJ5919BE3/TR13 should be based on RoHS compliance requirements and tolerance specifications. SMBJ5919BE3/TR13 is compliant with ROHS3 and offers a tighter tolerance at ±5%. Both devices are active, and their electrical and mechanical parameters are matched as per category requirements. Inventory levels may also be factored into selection when strict compliance or specification parameters are specified.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting SMBJ5919A/TR13 with SMBJ5919BE3/TR13?
A1: Substitution is validated by matching nominal Zener voltage (5.6 V), power rating (2 W), impedance (2 Ohms), leakage current (5 µA @ 3 V), forward voltage (1.2 V @ 200 mA), operating temperature range (-65°C ~ 150°C), mounting type (surface mount), package (DO-214AA, SMB), supplier device package (SMBJ DO-214AA), and electrical compliance parameters.

Q2: Is package compatibility maintained between SMBJ5919A/TR13 and SMBJ5919BE3/TR13?
A2: Yes, both components utilize the DO-214AA, SMB surface-mount package and SMBJ device outline.

Q3: How does tolerances affect substitution choices?
A3: SMBJ5919A/TR13 has a ±10% tolerance, while SMBJ5919BE3/TR13 has a ±5% tolerance. Both are parametric equivalents, but the tighter tolerance may support applications requiring stricter voltage control.

Q4: What regulatory compliance differences exist between the parts?
A4: SMBJ5919A/TR13 is RoHS non-compliant, whereas SMBJ5919BE3/TR13 is ROHS3 compliant. Selection should reflect compliance requirements specific to the end application.

Q5: Are there differences in moisture sensitivity or environmental ratings?
A5: Both models have a Moisture Sensitivity Level (MSL) of 1 (Unlimited) and REACH Unaffected status, making them suitable for environments where these ratings are required.

Q6: Can these Zener diodes be directly interchanged in a design?
A6: Direct interchange is possible where electrical parameters, mechanical form factor, and required compliance criteria align with specification requirements.
