Engineering Selection Recommendations

All three part numbers—BZX79-B4V7,113, BZX79-B4V7,133, and BZX79-B4V7,143—are manufactured by Nexperia USA Inc. and maintain identical electrical and mechanical specifications. Each part is Active in product status and fully compliant with RoHS3 requirements.

Selection between these parts is based on availability and supply chain considerations rather than technical performance differences. All parts are suitable for applications requiring a 4.7 V zener diode with 400 mW power rating in through-hole DO-35 axial packaging.

The parts carry REACH Unaffected status and are classified under ECCN EAR99 with HTSUS code 8541.10.0050. Moisture sensitivity level 1 (Unlimited) indicates no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B4V7,133 or BZX79-B4V7,143 be used as direct replacements for BZX79-B4V7,113?

A: Yes. All three part numbers share identical electrical specifications (4.7 V nominal zener voltage, 400 mW power rating, ±2% tolerance) and mechanical packaging (DO-35 axial through-hole). Direct substitution is supported without circuit modification.

Q: Are there differences in performance between the three part numbers?

A: No. The electrical characteristics, operating temperature range, impedance, and all other specified parameters are identical across BZX79-B4V7,113, BZX79-B4V7,133, and BZX79-B4V7,143.

Q: What does the suffix designation (113, 133, 143) indicate?

A: The suffix designations represent different tape and reel packaging configurations or manufacturing batches from Nexperia USA Inc. The electrical and mechanical specifications remain unchanged.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions.

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

A: Yes. All three parts are rated for operating temperatures from -65°C to 200°C, supporting high-temperature circuit applications within this range.

Q: What is the package type for these zener diodes?
