Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX84J-C22,115 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Parameters (Must Match):

• Nominal Zener voltage: 22 V
• Maximum power dissipation: 550 mW
• Maximum impedance: 25 Ohms
• Reverse leakage current: 50 nA @ 15.4 V
• Forward voltage: 1.1 V @ 100 mA
• Operating temperature range: -65°C to 150°C

Mechanical & Compliance Parameters (Must Match):

• Package type: SOD-323F (SC-90)
• Mounting type: Surface Mount
• Automotive grade qualification: AEC-Q101
• RoHS compliance status

The BZX84J-B22,115 is classified as a parametric equivalent because it maintains all critical electrical specifications while offering a tighter tolerance specification (±2% versus ±5%), making it suitable for applications requiring higher precision voltage regulation.

Parameter Comparison

Engineering Selection Recommendations

Both the BZX84J-C22,115 and BZX84J-B22,115 are Active products with full automotive qualification under AEC-Q101 standard, ensuring compliance with automotive reliability and quality requirements. The primary distinction between these parts is the voltage tolerance specification: the main part carries ±5% tolerance, while the substitute carries ±2% tolerance.

Selection between these parts depends on circuit tolerance requirements. The BZX84J-B22,115 substitute is suitable for applications requiring tighter voltage regulation accuracy due to its narrower tolerance band. Both parts are ROHS3 compliant and carry identical electrical performance across all other specified parameters, including power dissipation, impedance, leakage current, and operating temperature range.

The SOD-323F package and surface mount configuration are identical for both parts, ensuring direct PCB layout compatibility without design modification. Both parts are manufactured by the same corporate entity (Nexperia/NXP), providing consistent quality and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the BZX84J-B22,115 be used as a direct replacement for the BZX84J-C22,115?

A: Yes. The BZX84J-B22,115 is electrically and mechanically compatible with the BZX84J-C22,115. Both parts share identical nominal Zener voltage (22 V), maximum power rating (550 mW), impedance (25 Ohms), and operating temperature range (-65°C to 150°C). The substitute part features a tighter tolerance specification (±2% versus ±5%), which provides improved voltage regulation accuracy without compromising any other electrical characteristics.

Q: Are there any package or mounting differences between these parts?

A: No. Both the BZX84J-C22,115 and BZX84J-B22,115 use the identical SOD-323F package (SC-90 case) and surface mount configuration. PCB footprints, solder pad layouts, and component placement are identical, requiring no design or assembly modifications.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both parts carry Automotive grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards. Both are ROHS3 compliant and suitable for automotive and industrial applications requiring regulated voltage protection.

Q: What is the significance of the tolerance difference between ±5% and ±2%?

A: The tolerance specification defines the allowable deviation of the actual Zener voltage from the nominal 22 V rating. The BZX84J-C22,115 (±5%) allows actual voltage between 20.9 V and 23.1 V, while the BZX84J-B22,115 (±2%) constrains actual voltage between 21.56 V and 22.44 V. Applications requiring precise voltage regulation benefit from the tighter tolerance of the substitute part.

Q: Are there any electrical performance differences in leakage current or forward voltage?

A: No. Both parts specify identical reverse leakage current (50 nA @ 15.4 V) and forward voltage (1.1 V @ 100 mA). All electrical performance characteristics except tolerance are identical between the two parts.

Q: Can the BZX84J-C22,115 be used in place of the BZX84J-B22,115?

A: The BZX84J-C22,115 can be used in applications designed for the BZX84J-B22,115 only if the circuit design tolerates the wider ±5% voltage tolerance. Applications requiring the tighter ±2% tolerance specification of the substitute part cannot use the main part as a replacement.
