Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX79-C22,113 is determined by equivalence in the following critical parameters: nominal Zener voltage (22 V), maximum power rating (400 mW), impedance specification (55 Ohms maximum), forward voltage characteristics (900 mV @ 10 mA), operating temperature range (-65°C to 200°C), and through-hole axial package configuration (DO-204AH, DO-35, ALF2).

Voltage tolerance variations (±5% versus ±2%) are permitted substitution differentiators, as tighter tolerance variants (±2%) provide enhanced precision while maintaining functional compatibility with ±5% tolerance applications. Packaging format variations (Cut Tape versus Bulk) do not affect electrical equivalence and represent procurement format options only.

All identified substitute parts maintain identical nominal Zener voltage, maximum power dissipation, impedance, forward voltage, operating temperature range, and through-hole axial package type. Reverse leakage current specifications vary between measurement conditions (700 mV versus 15.4 V) but do not constitute functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical equivalence to the BZX79-C22,113 across the critical performance parameters. Selection among equivalent options is determined by application-specific requirements and procurement constraints.

BZX79-B22,113 and BZX79-B22,143 offer tighter voltage tolerance (±2%) compared to the primary part (±5%), providing enhanced precision for applications requiring stricter Zener voltage regulation. Both variants maintain identical power rating, impedance, forward voltage, and operating temperature specifications. These parts are suitable for direct substitution in precision voltage reference circuits.

BZX79-C22,133 and BZX79-C22,143 maintain the original ±5% voltage tolerance specification and are electrically identical to the BZX79-C22,113. These parts differ only in packaging format (Bulk versus Cut Tape) and represent alternative procurement options without functional differentiation.

All substitute parts carry ROHS3 compliance and REACH Unaffected status where specified, ensuring regulatory alignment with the primary component. Through-hole axial package configuration (DO-204AH, DO-35, ALF2) is consistent across all options, enabling direct mechanical interchangeability in PCB applications.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B22,113 replace BZX79-C22,113 in my circuit?

A: Yes. The BZX79-B22,113 is electrically equivalent with identical nominal Zener voltage (22 V), maximum power (400 mW), impedance (55 Ohms), forward voltage (900 mV @ 10 mA), and operating temperature range (-65°C to 200°C). The primary difference is tighter voltage tolerance (±2% versus ±5%), which provides enhanced regulation precision. Through-hole axial package configuration is identical.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) and Bulk packaging represent different procurement formats for the same electrical component. Cut Tape packaging provides individual components on carrier tape suitable for automated assembly equipment. Bulk packaging provides loose components in larger quantities. Electrical performance and mechanical specifications are identical between packaging formats.

Q: Are BZX79-C22,133 and BZX79-C22,143 interchangeable with BZX79-C22,113?

A: Yes. Both parts are electrically identical to BZX79-C22,113, maintaining the same 22 V nominal voltage, ±5% tolerance, 400 mW power rating, 55 Ohms impedance, and through-hole axial package. These parts differ only in packaging format (Bulk versus Cut Tape) and represent alternative procurement sources.

Q: Does voltage tolerance affect circuit compatibility?

A: Voltage tolerance defines the acceptable range of Zener voltage variation from the nominal 22 V specification. The BZX79-C22,113 with ±5% tolerance operates between 20.9 V and 23.1 V. The BZX79-B22 series with ±2% tolerance operates between 21.56 V and 22.44 V. Selection depends on circuit requirements for voltage regulation precision. Tighter tolerance variants (±2%) are suitable for applications requiring stricter voltage control.

Q: Can I use these Zener diodes in high-temperature applications?

A: Yes. All substitute parts are rated for operating temperatures from -65°C to 200°C, enabling deployment in high-temperature environments. Verify that circuit design and PCB materials support the specified temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: ROHS3 compliance is confirmed for BZX79-C22,113, BZX79-B22,113, BZX79-C22,133, and BZX79-C22,143. Compliance status for BZX79-B22,143 is not specified in available documentation. Verify compliance requirements with your procurement or quality assurance department if regulatory certification is mandatory.
