BZT52C11LP-TP Equivalent & Substitute Parts

Part Overview

The BZT52C11LP-TP is a Zener diode manufactured by Micro Commercial Co, rated at 11 V nominal with 100 mW maximum power dissipation in a surface mount SOD-882 package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, production continuity, and component sourcing.

Zener diodes in this voltage and power class are used for voltage regulation, overvoltage protection, and reference voltage applications in electronic circuits. The obsolete status of the BZT52C11LP-TP requires engineers to evaluate active alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C11LP-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Nominal Zener voltage of 11 V (primary functional requirement)
• Zener voltage tolerance within acceptable design margins
• Reverse leakage current characteristics
• Forward voltage characteristics
• Operating temperature range coverage (-65°C to 150°C minimum)

Mechanical Compatibility Criteria:

• Surface mount technology
• Package form factor compatibility
• Moisture sensitivity level

Regulatory Compliance:

• RoHS3 compliance status

The BZX884-C11,315 manufactured by Nexperia USA Inc. qualifies as a substitute based on matching nominal Zener voltage, operating temperature range, reverse leakage current, forward voltage characteristics, surface mount technology, and RoHS3 compliance. The substitute offers enhanced power dissipation capability (250 mW versus 100 mW) and improved impedance characteristics, making it suitable for applications requiring the original part's electrical function.

Parameter Comparison

Engineering Selection Recommendations

The BZX884-C11,315 is an active substitute for the obsolete BZT52C11LP-TP. Selection of this substitute is based on the following factors:

Product Status: The BZX884-C11,315 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical Equivalence: Both parts share identical nominal Zener voltage (11 V), reverse leakage current (100 nA @ 8 V), and forward voltage characteristics (900 mV @ 10 mA). The substitute exhibits tighter Zener voltage tolerance (±5% versus ±5.45%) and lower impedance (10 Ohms versus 20 Ohms), representing improved performance characteristics.

Regulatory Compliance: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), meeting environmental and handling requirements.

Enhanced Capability: The BZX884-C11,315 provides 250 mW maximum power dissipation compared to 100 mW in the original part, offering design margin for thermal performance in voltage regulation and protection applications.

Automotive Qualification: The substitute carries AEC-Q100 qualification, indicating suitability for automotive-grade applications where applicable.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C11,315 be used as a direct replacement for the BZT52C11LP-TP?

A: Yes. Both parts share the same nominal Zener voltage (11 V), operating temperature range (-65°C to 150°C), reverse leakage current (100 nA @ 8 V), forward voltage characteristics (900 mV @ 10 mA), surface mount technology, SOD-882 package form factor, and RoHS3 compliance status. The substitute is electrically and mechanically compatible.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Product status—the BZX884-C11,315 is active while the BZT52C11LP-TP is obsolete; (2) Power dissipation—250 mW versus 100 mW; (3) Zener voltage tolerance—±5% versus ±5.45%; (4) Impedance—10 Ohms versus 20 Ohms; (5) Manufacturer—Nexperia USA Inc. versus Micro Commercial Co; (6) Qualification—the substitute carries AEC-Q100 automotive qualification.

Q: Are there package compatibility concerns?

A: No. Both parts use the SOD-882 surface mount package. The physical form factor and land pattern are compatible for PCB assembly without layout modifications.

Q: Does the higher power rating of the substitute affect circuit operation?

A: No. The 250 mW rating of the BZX884-C11,315 represents a design margin enhancement. Circuits designed for 100 mW operation will function within the substitute's specifications. The higher power capability does not alter voltage regulation or protection characteristics at equivalent current levels.

Q: What is the significance of the AEC-Q100 qualification on the substitute?

A: AEC-Q100 qualification indicates the BZX884-C11,315 meets automotive industry reliability and quality standards. This qualification is relevant for applications in automotive or similarly demanding environments. Non-automotive applications are not affected by this qualification status.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity). No compliance barriers exist for substitution.
