Key Parameters

Substitute Part Grouping Explanation

Substitution within the BZX79 Zener diode family is determined by the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Voltage - Zener (Nom): 75 V (fixed across all equivalents)
• Power - Max: 400 mW (fixed across all equivalents)
• Mounting Type: Through Hole (fixed across all equivalents)
• Package / Case: DO-204AH, DO-35, Axial (fixed across all equivalents)
• Operating Temperature Range: -65°C to 200°C (fixed across all equivalents)

Variable Parameters Defining Substitute Groups:

• Tolerance: ±5% (main part) or ±2% (substitute variants)
• Packaging Format: Tape & Reel (TR), Cut Tape (CT), or Bulk
• Manufacturer: Nexperia USA Inc. or NXP USA Inc. / NXP Semiconductors

All substitute parts maintain identical electrical performance specifications for Zener voltage, power rating, impedance, reverse leakage current, and forward voltage characteristics. Substitution is valid when packaging format and tolerance requirements are compatible with circuit design specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and are manufactured by Nexperia or NXP entities, ensuring continued availability and technical support.

BZX79-B75,113 and BZX79-B75,133 offer tighter tolerance specifications (±2%) compared to the main part (±5%), providing improved Zener voltage accuracy. These variants are suitable for applications requiring stricter voltage regulation performance. Both are ROHS3 compliant where specified.

BZX79-C75,133 maintains the ±5% tolerance specification of the main part while offering bulk packaging availability. This variant provides equivalent electrical performance with alternative supply format options.

Selection between substitute parts depends on:

• Required tolerance specification (±2% for BZX79-B series, ±5% for BZX79-C series)
• Packaging format requirements (Tape & Reel, Cut Tape, or Bulk)
• Inventory availability and procurement lead times
• RoHS compliance certification requirements for end-use applications

All parts are REACH Unaffected and classified under ECCN EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B75,113 replace BZX79-C75,113 in my circuit?

A: Yes. Both parts share identical electrical specifications for Zener voltage (75 V), power rating (400 mW), impedance (255 Ohms), forward voltage, and operating temperature range. The primary difference is tolerance specification: BZX79-B75,113 provides ±2% tolerance versus ±5% for BZX79-C75,113. This substitution is valid when tighter voltage accuracy is acceptable or required.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly equipment. Cut Tape (CT) provides the same carrier tape format in smaller quantities, cut to specific lengths. Bulk packaging supplies loose components without carrier tape. All three formats contain identical components; packaging format selection depends on assembly process requirements and order quantity.

Q: Are all substitute parts RoHS3 compliant?

A: BZX79-C75,113 and BZX79-B75,133 are explicitly specified as ROHS3 Compliant. RoHS compliance status is not specified in the provided data for BZX79-B75,113 and BZX79-C75,133. Verify RoHS compliance requirements with the component supplier for applications requiring regulatory certification.

Q: Can I use BZX79-C75,133 as a substitute for BZX79-C75,113?

A: Yes. Both parts are electrically identical with matching 75 V Zener voltage, 400 mW power rating, ±5% tolerance, and operating temperature range. The difference is packaging format: BZX79-C75,113 is supplied in Tape & Reel format while BZX79-C75,133 is supplied in Bulk format. Substitution is valid when bulk packaging is compatible with your procurement and assembly processes.

Q: What does ±2% tolerance mean compared to ±5%?

A: Tolerance specifies the allowable deviation of the Zener voltage from the nominal 75 V rating. ±2% tolerance (BZX79-B series) limits deviation to ±1.5 V, resulting in a Zener voltage range of 73.5 V to 76.5 V. ±5% tolerance (BZX79-C series) allows deviation to ±3.75 V, resulting in a range of 71.25 V to 78.75 V. Tighter tolerance provides more precise voltage regulation but may affect component cost and availability.

Q: Are all substitute parts through-hole components?

A: Yes. All listed parts, including the main part BZX79-C75,113 and all substitutes, are through-hole mounted components in DO-204AH/DO-35 axial package configuration. No surface-mount alternatives are included in this substitution list.
