Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZV85-C18,113 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Zener voltage (Vz) must equal 18 V nominal with ±5% tolerance
• Operating temperature range must encompass -65°C to 200°C
• Forward voltage and reverse leakage characteristics must be compatible with circuit design

Mechanical Compatibility Criteria:

• Through-hole mounting type required
• Axial package configuration acceptable
• DO-41 or equivalent axial form factor

Regulatory Compliance:

• RoHS3 compliance mandatory
• REACH Unaffected status required

The 1N5355BRLG qualifies as a direct substitute based on matching Zener voltage (18 V), tolerance (±5%), operating temperature range (-65°C to 200°C), through-hole mounting, axial package configuration, and regulatory compliance status. The higher power rating (5 W versus 1.3 W) and improved impedance characteristics (2.5 Ohms versus 20 Ohms) provide enhanced performance margins in applications where the original specification is met or exceeded.

Engineering Selection Recommendations

Primary Selection: BZV85-C18,113

The BZV85-C18,113 remains the primary component choice when available. It is manufactured by Nexperia USA Inc., carries Active product status, and maintains full RoHS3 and REACH compliance. The 1.3 W power rating and 20 Ohm impedance are specified for the intended application.

Alternative Selection: 1N5355BRLG

The 1N5355BRLG manufactured by onsemi is a qualified substitute when the BZV85-C18,113 is unavailable. Both components share identical Zener voltage (18 V) and tolerance (±5%), identical operating temperature range (-65°C to 200°C), and equivalent regulatory compliance (RoHS3 Compliant, REACH Unaffected). Both employ through-hole axial mounting. The 1N5355BRLG provides superior power dissipation capability (5 W versus 1.3 W) and lower impedance (2.5 Ohms versus 20 Ohms), making it suitable for applications requiring enhanced performance margins. The higher reverse leakage current (500 nA @ 13.7 V versus 50 nA @ 12.5 V) must be evaluated against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1N5355BRLG directly replace the BZV85-C18,113 in my circuit?

A: Yes, the 1N5355BRLG is a direct substitute. Both components have identical Zener voltage (18 V), tolerance (±5%), and operating temperature range (-65°C to 200°C). Both are through-hole axial devices with RoHS3 compliance. The 1N5355BRLG provides higher power rating and lower impedance, which are compatible with applications designed for the BZV85-C18,113.

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

A: The primary differences are power rating (1.3 W for BZV85-C18,113 versus 5 W for 1N5355BRLG), impedance (20 Ohms versus 2.5 Ohms), and reverse leakage current (50 nA @ 12.5 V versus 500 nA @ 13.7 V). The 1N5355BRLG offers enhanced power dissipation and lower impedance characteristics.

Q: Are the package dimensions identical?

A: Both components use through-hole axial packaging. The BZV85-C18,113 is specified as DO-204AL/DO-41, and the 1N5355BRLG is specified as T-18 Axial. Both are compatible with standard through-hole PCB layouts designed for axial components.

Q: Do both parts meet regulatory requirements?

A: Yes. Both the BZV85-C18,113 and 1N5355BRLG are RoHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: Which part should I use for new designs?

A: Selection depends on application requirements and availability. The BZV85-C18,113 is the specified component. The 1N5355BRLG is a qualified alternative when the primary part is unavailable or when the enhanced power rating and lower impedance provide design advantages.

Q: Can I use the 1N5355BRLG in a circuit designed for lower power dissipation?

A: Yes. The 1N5355BRLG's higher power rating (5 W) does not prevent its use in applications requiring lower power dissipation. The component will operate within its specifications in such applications.
