Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C36LP-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage rating must be 36 V nominal
• Operating temperature range must encompass -65°C to 150°C
• Forward voltage characteristics must match at specified test conditions
• Impedance maximum rating must not exceed 90 Ohms
• Reverse leakage current specifications must be compatible with circuit requirements

Mechanical Compatibility Criteria:

• Surface mount mounting type
• SOD-882 package footprint compatibility
• RoHS3 compliance requirement

The BZX884-C36,315 manufactured by Nexperia USA Inc. meets these substitution criteria. While this part features increased power dissipation (250 mW versus 100 mW) and improved tolerance (±5% versus ±5.56%), it maintains electrical equivalence in all critical parameters and maintains the same package footprint and compliance standards.

Engineering Selection Recommendations

The BZX884-C36,315 is a direct substitute for the obsolete BZT52C36LP-TP based on the following factors:

Product Status Consideration: The BZX884-C36,315 maintains active product status with Nexperia USA Inc., ensuring long-term availability and supply chain continuity compared to the obsolete BZT52C36LP-TP.

Compliance and Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The BZX884-C36,315 includes AEC-Q100 automotive qualification and REACH unaffected status, providing additional quality assurance documentation.

Electrical Performance: The substitute part maintains identical nominal zener voltage (36 V), forward voltage characteristics (900 mV @ 10 mA), impedance maximum (90 Ohms), and operating temperature range (-65°C to 150°C). The improved tolerance (±5% versus ±5.56%) and reduced reverse leakage current (50 nA versus 100 nA) represent performance enhancements.

Power Dissipation: The BZX884-C36,315 features 250 mW maximum power dissipation compared to 100 mW in the original part. This increased rating provides design margin and thermal performance improvement without introducing compatibility issues in applications designed for the lower-power original component.

Package Compatibility: Both parts utilize SOD-882 surface mount packaging with identical footprints, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C36,315 be used as a direct replacement for the BZT52C36LP-TP in existing designs?

A: Yes. The BZX884-C36,315 maintains electrical equivalence across all critical parameters including zener voltage (36 V), forward voltage (900 mV @ 10 mA), impedance (90 Ohms maximum), and operating temperature range (-65°C to 150°C). Both parts use identical SOD-882 surface mount packaging with matching footprints.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Micro Commercial Co versus Nexperia USA Inc.), product status (obsolete versus active), power rating (100 mW versus 250 mW), tolerance (±5.56% versus ±5%), and reverse leakage current (100 nA versus 50 nA). The BZX884-C36,315 includes AEC-Q100 automotive qualification.

Q: Does the higher power rating of the BZX884-C36,315 affect circuit compatibility?

A: No. The increased power dissipation rating (250 mW versus 100 mW) in the substitute part does not create compatibility issues. Applications designed for the 100 mW original part operate within the thermal and electrical specifications of the 250 mW substitute.

Q: Are there package considerations when substituting these parts?

A: Both parts use SOD-882 surface mount packaging. No package changes or PCB layout modifications are required for substitution.

Q: What compliance standards apply to both parts?

A: Both the BZT52C36LP-TP and BZX884-C36,315 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity ratings. The BZX884-C36,315 additionally carries AEC-Q100 automotive qualification and REACH unaffected status.

Q: Why is the BZT52C36LP-TP classified as obsolete?

A: The BZT52C36LP-TP is listed as obsolete product status by the manufacturer. The BZX884-C36,315 maintains active status, ensuring continued availability and manufacturing support.
