BZX79-C47,113 Equivalent & Substitute Parts

Part Overview

The BZX79-C47,113 is a through-hole zener diode manufactured by Nexperia USA Inc., rated at 47 V nominal zener voltage with 400 mW maximum power dissipation. This component operates across a temperature range of -65°C to 200°C and is packaged in the DO-204AH/DO-35 axial configuration. The part maintains Active product status and carries ROHS3 compliance certification.

Substitute parts are identified when electrical and mechanical parameters remain identical across the component specification. Equivalent zener diodes with matching voltage ratings, power ratings, impedance characteristics, and package configurations can be directly substituted in circuit applications without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX79-C47,113 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Zener voltage rating: 47 V nominal
• Power dissipation rating: 400 mW maximum
• Impedance specification: 170 Ohms maximum
• Reverse leakage current: 50 nA @ 700 mV
• Forward voltage: 900 mV @ 10 mA maximum
• Operating temperature range: -65°C to 200°C
• Package configuration: DO-204AH/DO-35 axial through-hole
• Supplier device package: ALF2
• Voltage tolerance: ±5%

All identified substitute parts maintain identical electrical performance characteristics and physical package specifications. Substitution is valid across different packaging formats (Cut Tape versus Bulk) and different manufacturer designations when the base product number BZX79-C47 remains constant with matching suffix codes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BZX79-C47,113, BZX79-C47,133, and BZX79-C47,143—are functionally equivalent zener diodes with identical electrical specifications and package configurations. Selection between these parts is determined by availability, packaging format requirements, and regulatory compliance needs.

BZX79-C47,113 and BZX79-C47,133 are both supplied by Nexperia USA Inc. in Cut Tape packaging format. Both maintain ROHS3 compliance and REACH Unaffected status. The primary distinction is inventory availability: BZX79-C47,113 has 10,854 pieces in stock, while BZX79-C47,133 has 1,205 pieces available.

BZX79-C47,143 is supplied by NXP Semiconductors in Bulk packaging format with significantly higher inventory availability at 176,005 pieces. This part maintains REACH Unaffected status. RoHS compliance status is not specified for this variant.

For applications requiring Cut Tape packaging, either BZX79-C47,113 or BZX79-C47,133 is appropriate. For applications where Bulk packaging is acceptable and maximum inventory availability is prioritized, BZX79-C47,143 is suitable. All three parts are Active products suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can BZX79-C47,133 be used as a direct replacement for BZX79-C47,113?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical parameters: 47 V zener voltage, 400 mW power rating, 170 Ohms maximum impedance, and DO-204AH/DO-35 axial package configuration. The parts differ only in packaging format (both Cut Tape) and inventory levels.

Q: What is the difference between BZX79-C47,143 and the other two substitutes?

A: BZX79-C47,143 is manufactured by NXP Semiconductors and supplied in Bulk packaging rather than Cut Tape. All electrical specifications remain identical: 47 V nominal zener voltage, 400 mW maximum power, 170 Ohms impedance, and through-hole axial mounting. The primary differences are supplier, packaging format, and inventory availability.

Q: Are there packaging compatibility concerns when substituting between Cut Tape and Bulk formats?

A: No. Both packaging formats contain the same DO-204AH/DO-35 axial component. The packaging format affects only the delivery method and handling during assembly. The physical component and electrical performance are identical.

Q: Do all substitute parts meet the same compliance standards?

A: BZX79-C47,113 and BZX79-C47,133 are both ROHS3 compliant and REACH Unaffected. BZX79-C47,143 is REACH Unaffected; RoHS compliance status is not specified in the provided data. For applications with mandatory ROHS3 requirements, BZX79-C47,113 or BZX79-C47,133 is required.

Q: Can these parts be used in high-temperature applications?

A: Yes. All three parts operate across the temperature range of -65°C to 200°C, supporting both cryogenic and elevated-temperature circuit environments.

Q: What is the significance of the ±5% tolerance specification?

A: The ±5% tolerance indicates the acceptable variation in the 47 V zener voltage rating across the component population. This tolerance applies equally to all three substitute parts and determines the precision of voltage regulation in circuit applications.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All three parts maintain identical electrical characteristics: 50 nA reverse leakage current at 700 mV, 900 mV maximum forward voltage at 10 mA, and 170 Ohms maximum impedance. Substitution does not affect circuit performance.
