Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N6005B-TP is determined by the following critical electrical and mechanical parameters:

Electrical Matching Criteria:

• Zener voltage (Vz): 16 V nominal
• Tolerance: ±5%
• Power rating: 500 mW maximum
• Forward voltage (Vf): 1.5 V maximum at 100 mA
• Operating temperature range: -65°C to 200°C

Mechanical Matching Criteria:

• Package type: DO-35 (DO-204AH)
• Mounting configuration: Through-hole axial leads

The BZX79C16-T50A meets all specified electrical parameters within the defined tolerances and operates across the required temperature range. Both components share identical nominal Zener voltage, tolerance, power rating, forward voltage specification, and operating temperature limits. The mechanical package configuration is identical, ensuring direct pin-compatible substitution in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The BZX79C16-T50A is a direct functional equivalent to the 1N6005B-TP for applications requiring a 16 V Zener diode with 500 mW power dissipation in a DO-35 package.

Substitution Basis:

The BZX79C16-T50A maintains all critical electrical specifications within the defined operating parameters. Both components are ROHS3 compliant, ensuring regulatory alignment. The substitute part is manufactured by onsemi and carries active product status, providing assured long-term availability and supply chain stability compared to the obsolete 1N6005B-TP.

The impedance specification of the BZX79C16-T50A (40 Ohms maximum) is marginally higher than the original part (36 Ohms maximum), remaining within acceptable circuit design tolerances for standard Zener regulation applications. The reverse leakage current of the substitute part is lower (50 nA at 11.2 V versus 100 nA at 12 V), representing improved performance characteristics.

Both components share identical mechanical packaging, enabling direct board-level substitution without layout modifications or mechanical rework.

Frequently Asked Questions (FAQ)

Q: Can the BZX79C16-T50A be used as a direct replacement for the 1N6005B-TP?

A: Yes. The BZX79C16-T50A is electrically and mechanically compatible with the 1N6005B-TP. Both components feature identical nominal Zener voltage (16 V), tolerance (±5%), power rating (500 mW), forward voltage specification (1.5 V @ 100 mA), and operating temperature range (-65°C to 200°C). The DO-35 package configuration is identical, enabling direct pin-compatible substitution.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer and product status. The 1N6005B-TP is obsolete and manufactured by Micro Commercial Co, while the BZX79C16-T50A is active and manufactured by onsemi. The BZX79C16-T50A exhibits slightly higher impedance (40 Ohms versus 36 Ohms) and lower reverse leakage current (50 nA versus 100 nA), both representing acceptable variations for Zener diode applications.

Q: Are there any compliance or certification differences?

A: Both components are ROHS3 compliant. The BZX79C16-T50A carries REACH Unaffected status, providing additional regulatory documentation. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications.

Q: Will the BZX79C16-T50A work in existing circuit designs without modification?

A: Yes. The identical electrical specifications and DO-35 through-hole package configuration ensure functional compatibility without circuit redesign or board layout changes.

Q: What is the availability status of the substitute part?

A: The BZX79C16-T50A is an active product with established supply chain availability. The 1N6005B-TP is obsolete, making the substitute part the recommended choice for new designs and ongoing production requirements.
