BZV85-C43,113 Equivalent & Substitute Parts

Part Overview

The BZV85-C43,113 is an active-status Zener diode manufactured by Nexperia USA Inc., rated for 43 V nominal Zener voltage with 1.3 W maximum power dissipation. This component is packaged in DO-41 axial through-hole configuration and is ROHS3 compliant. Substitute parts are identified when electrical parameters—specifically Zener voltage, tolerance, and power rating—align within acceptable operating ranges, and when mechanical compatibility through equivalent package specifications is confirmed.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZV85-C43,113 is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

• Zener voltage (Vz) must equal 43 V nominal
• Tolerance must be ±5%
• Operating temperature range must encompass -65°C to 200°C
• Mounting type must be Through Hole
• Package configuration must be axial or equivalent mechanical form factor

Secondary Compatibility Factors:

• Power rating may exceed the original specification (higher power rating is acceptable for thermal margin)
• Impedance and reverse leakage characteristics may vary within manufacturer specifications
• Forward voltage characteristics may differ based on die design and manufacturer process

The substitute part 1N5367BRLG meets all primary criteria with identical Zener voltage, tolerance, and operating temperature range. The higher power rating (5 W versus 1.3 W) and improved impedance characteristics (20 Ohms versus 75 Ohms) provide enhanced performance margin without compromising circuit compatibility.

Engineering Selection Recommendations

BZV85-C43,113 (Primary Part):

• Nexperia USA Inc. manufacture with active product status
• ROHS3 compliant and REACH unaffected
• Suitable for applications requiring 1.3 W maximum power dissipation
• DO-41 axial package provides standard through-hole mounting

1N5367BRLG (Substitute Part):

• onsemi manufacture with active product status
• ROHS3 compliant and REACH unaffected
• Suitable for applications requiring up to 5 W power dissipation
• T-18 axial package provides standard through-hole mounting
• Lower impedance (20 Ohms) provides improved voltage regulation characteristics
• Higher power rating accommodates thermal margin in power-constrained applications

Both parts maintain identical Zener voltage (43 V) and tolerance (±5%), with operating temperature ranges spanning -65°C to 200°C. Selection between these parts depends on circuit power dissipation requirements and available board space for package form factor.

Frequently Asked Questions (FAQ)

Q: Can 1N5367BRLG directly replace BZV85-C43,113 in existing designs?

A: Yes. Both parts share identical Zener voltage (43 V), tolerance (±5%), and operating temperature range (-65°C to 200°C). The substitute part features higher power rating (5 W versus 1.3 W) and lower impedance (20 Ohms versus 75 Ohms), which are compatible with circuit requirements for the original part. Through-hole axial mounting is maintained in both configurations.

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

A: The primary differences are power dissipation capability (1.3 W versus 5 W) and impedance characteristics (75 Ohms versus 20 Ohms). The 1N5367BRLG provides superior voltage regulation due to lower impedance. Reverse leakage current is higher in the substitute part (500 nA @ 32.7 V versus 50 nA @ 30 V), and forward voltage is slightly elevated (1.2 V @ 1 A versus 1 V @ 50 mA).

Q: Are package dimensions compatible between DO-41 and T-18 axial packages?

A: Both BZV85-C43,113 and 1N5367BRLG use axial through-hole package configurations. DO-41 and T-18 are standard axial package designations. Physical dimensions may differ; board layout and lead spacing must be verified for mechanical fit in existing designs.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both BZV85-C43,113 and 1N5367BRLG are ROHS3 compliant and REACH unaffected. Both carry active product status from their respective manufacturers.

Q: Which part should be selected for high-temperature applications?

A: Both parts support the identical operating temperature range of -65°C to 200°C. Selection is based on power dissipation requirements and impedance characteristics rather than temperature capability.
