BZX79-B6V8,113 Equivalent & Substitute Parts

Part Overview

The BZX79-B6V8,113 is a 6.8 V Zener diode rated for 400 mW continuous power dissipation, manufactured by Nexperia USA Inc. in the ALF2 package configuration. This component is classified as an active product and is ROHS3 compliant. Zener diodes of this specification are used in voltage regulation, overvoltage protection, and reference voltage circuits where precise voltage clamping at 6.8 V is required. Alternative part numbers become necessary when addressing supply chain constraints, packaging format requirements, or specific inventory availability while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZX79-B6V8,113 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Zener voltage (Vz) of 6.8 V nominal
• Tolerance specification of ±2%
• Power rating of 400 mW minimum
• Through-hole axial mounting configuration
• Operating temperature range of -65°C to 200°C minimum
• Maximum impedance (Zzt) of 15 Ohms or lower

Parametric Equivalent Parts (BZX79-B6V8,133 and BZX79-B6V8,143) meet all primary substitution criteria identically. These parts differ only in packaging format (Cut Tape versus Bulk) and are direct electrical equivalents manufactured by Nexperia USA Inc. or NXP USA Inc.

Similar Parts (1N754A) share the same 6.8 V nominal Zener voltage and reverse leakage characteristics but differ in power rating (500 mW versus 400 mW), tolerance (±5% versus ±2%), impedance (5 Ohms versus 15 Ohms), and package type (DO-7 versus ALF2). This part is classified as similar rather than parametric equivalent due to these deviations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Parametric Equivalents):

BZX79-B6V8,133 and BZX79-B6V8,143 are parametric equivalents of BZX79-B6V8,113. Both parts maintain identical electrical specifications and are manufactured by Nexperia USA Inc. or NXP USA Inc., both active product manufacturers. Selection between these three parts should be based on packaging format availability: Cut Tape (CT) for BZX79-B6V8,113 and BZX79-B6V8,133, or Bulk for BZX79-B6V8,143. All three parts are ROHS3 compliant and suitable for applications requiring the specified 6.8 V regulation voltage with ±2% tolerance.

For Similar Substitution (1N754A):

The 1N754A manufactured by Microchip Technology is a similar part with the same 6.8 V nominal Zener voltage but with the following deviations: higher power rating (500 mW), wider tolerance (±5%), lower impedance (5 Ohms), and different package type (DO-7). The 1N754A is RoHS non-compliant and has a reduced maximum operating temperature of 175°C. This part is suitable only for applications where the higher power rating and lower impedance are beneficial and where RoHS compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B6V8,133 be used as a direct replacement for BZX79-B6V8,113?

A: Yes. BZX79-B6V8,133 is a parametric equivalent with identical electrical specifications, including 6.8 V nominal Zener voltage, ±2% tolerance, 400 mW power rating, and -65°C to 200°C operating temperature range. The primary difference is packaging format (Cut Tape). Both are ROHS3 compliant and manufactured by Nexperia USA Inc.

Q: What is the difference between BZX79-B6V8,143 and BZX79-B6V8,113?

A: BZX79-B6V8,143 is electrically identical to BZX79-B6V8,113 in all specified parameters. The difference is packaging format: BZX79-B6V8,143 is supplied in Bulk format, while BZX79-B6V8,113 is supplied in Cut Tape (CT) format. Both are through-hole axial diodes with identical electrical performance.

Q: Is 1N754A a suitable replacement for BZX79-B6V8,113?

A: 1N754A shares the same 6.8 V nominal Zener voltage and reverse leakage characteristics but differs in four key parameters: power rating (500 mW versus 400 mW), tolerance (±5% versus ±2%), impedance (5 Ohms versus 15 Ohms), and maximum operating temperature (175°C versus 200°C). Additionally, 1N754A is RoHS non-compliant. Use 1N754A only when higher power dissipation capability is required and RoHS compliance is not mandated.

Q: What are the critical parameters for substituting BZX79-B6V8,113?

A: The critical parameters are: 6.8 V nominal Zener voltage, ±2% tolerance, 400 mW minimum power rating, through-hole axial mounting, and -65°C to 200°C operating temperature range. Any substitute must meet or exceed these specifications. Impedance must not exceed 15 Ohms.

Q: Can I use 1N754A in a circuit designed for BZX79-B6V8,113?

A: 1N754A can be used only if the circuit design accommodates the following differences: wider voltage tolerance (±5%), lower impedance (5 Ohms), higher power rating (500 mW), and reduced maximum operating temperature (175°C). If the circuit requires ±2% tolerance accuracy or operates above 175°C, 1N754A is not suitable. RoHS compliance requirements must also be evaluated.

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

A: Cut Tape (CT) packaging supplies individual components on tape for automated assembly equipment. Bulk packaging supplies loose components in larger quantities. Electrically and mechanically, the components are identical. Selection depends on assembly process requirements and order quantity.

Q: Are all substitute parts through-hole components?

A: Yes. BZX79-B6V8,113, BZX79-B6V8,133, BZX79-B6V8,143, and 1N754A are all through-hole axial-lead diodes. All are suitable for PCB insertion and wave soldering processes.
