BZT52C8V2LP-TP Equivalent & Substitute Parts

Part Overview

The BZT52C8V2LP-TP is a Zener diode manufactured by Micro Commercial Co, rated at 8.2 V nominal voltage 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 BZT52C8V2LP-TP requires engineers to identify functionally compatible alternatives that maintain circuit performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZT52C8V2LP-TP is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Zener voltage (Vz) must be 8.2 V nominal
• Operating temperature range must encompass -65°C to 150°C
• Reverse leakage current must not exceed 700 nA @ 5 V
• Forward voltage must not exceed 900 mV @ 10 mA
• RoHS3 compliance required

Mechanical Compatibility Criteria:

• Surface mount technology required
• Package footprint must be compatible with SOD-882 or equivalent land pattern

Performance Considerations:

• Power rating may exceed 100 mW (higher power rating is acceptable for thermal margin)
• Impedance may be lower than 15 Ohms (lower impedance provides improved performance)
• Tolerance may be tighter than ±6.1% (improved tolerance is acceptable)

The BZX884-C8V2,315 meets all substitution criteria and is identified as an equivalent part for the BZT52C8V2LP-TP.

Parameter Comparison

Engineering Selection Recommendations

The BZX884-C8V2,315 is a direct substitute for the BZT52C8V2LP-TP based on the following factors:

Electrical Equivalence: All critical electrical parameters match or exceed the original specification. The 8.2 V nominal zener voltage, reverse leakage current, and forward voltage characteristics are identical. The substitute provides tighter tolerance (±5% versus ±6.1%), lower impedance (10 Ohms versus 15 Ohms), and higher power rating (250 mW versus 100 mW), all of which represent equal or improved performance.

Compliance and Certification: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The BZX884-C8V2,315 carries AEC-Q100 automotive qualification and is manufactured by Nexperia USA Inc., an active supplier with current production status.

Availability and Supply Chain: The BZT52C8V2LP-TP is obsolete. The BZX884-C8V2,315 is in active production with documented inventory availability, ensuring long-term component sourcing for new designs and production continuity.

Package and Thermal Considerations: Both components use identical SOD-882 surface mount packaging, ensuring PCB footprint compatibility without layout modifications. The higher power rating of the substitute provides additional thermal margin in applications approaching the 100 mW limit.

Frequently Asked Questions (FAQ)

Q: Can the BZX884-C8V2,315 be used as a direct replacement for the BZT52C8V2LP-TP without circuit modifications?

A: Yes. The BZX884-C8V2,315 is electrically and mechanically compatible with the BZT52C8V2LP-TP. Both components share identical zener voltage, operating temperature range, package type, and critical electrical characteristics. No circuit modifications are required.

Q: What is the significance of the higher power rating (250 mW versus 100 mW) in the substitute part?

A: The higher power rating indicates the substitute can dissipate more heat without exceeding maximum junction temperature. This provides additional thermal margin and does not negatively affect circuit operation. Applications operating at or near the 100 mW limit benefit from this increased capability.

Q: Does the tighter tolerance (±5% versus ±6.1%) of the substitute part affect compatibility?

A: No. Tighter tolerance represents improved performance and is fully compatible with circuits designed for the original ±6.1% tolerance. The substitute will maintain zener voltage within a narrower band, which is acceptable for all applications requiring the original part.

Q: Are there package compatibility concerns between SOD-882 and DFN1006-2 designations?

A: The supplier device package designation (DFN1006-2) refers to the manufacturer's internal classification. The actual package / case for both parts is SOD-882, which is the industry-standard designation for the physical footprint. PCB layouts designed for SOD-882 are compatible with both parts.

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

A: AEC-Q100 is an automotive industry qualification standard. The BZX884-C8V2,315 meets this qualification, indicating it has undergone rigorous testing for automotive applications. This qualification is not a requirement for general-purpose applications but indicates higher reliability standards.

Q: Can the BZX884-C8V2,315 be used in applications where the original BZT52C8V2LP-TP was specified?

A: Yes. The substitute meets or exceeds all electrical and mechanical specifications of the original part. The obsolete status of the BZT52C8V2LP-TP makes the BZX884-C8V2,315 the appropriate choice for design updates, production continuity, and new component sourcing.
