BZX85C62-TAP Equivalent & Substitute Parts

Part Overview

The BZX85C62-TAP is an active-status zener diode manufactured by Vishay General Semiconductor - Diodes Division. This component is a 62 V, 1.3 W through-hole zener diode in DO-204AL (DO-41) axial package configuration, qualified to AEC-Q101 automotive standards and RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or supply chain considerations.

Substitute Part Grouping Explanation

Substitution of the BZX85C62-TAP is permissible when the following electrical and mechanical parameters are maintained or exceeded:

Critical Matching Parameters:

Zener voltage nominal value: 62 V
Voltage tolerance: ±5%
Package type: DO-204AL (DO-41) axial through-hole
Reverse leakage current: 500 nA @ 47 V or lower

Allowable Variation Parameters:

Power dissipation: Equal to or greater than 1.3 W
Impedance: Equal to or lower than 125 Ohms
Operating temperature range: Must encompass the application requirements within -55°C to 175°C

The substitute part 2EZ62D5/TR8 meets the critical matching parameters and provides enhanced power dissipation capability (2 W versus 1.3 W) and lower impedance (60 Ohms versus 125 Ohms), making it electrically compatible for direct substitution in applications where the BZX85C62-TAP is specified.

Engineering Selection Recommendations

Primary Selection: BZX85C62-TAP

The BZX85C62-TAP is the specified component and remains the primary selection. It carries AEC-Q101 automotive qualification and RoHS3 compliance, making it suitable for regulated automotive and industrial applications requiring environmental compliance documentation.

Substitute Selection: 2EZ62D5/TR8

The 2EZ62D5/TR8 is electrically compatible for direct substitution based on matched zener voltage, tolerance, reverse leakage current, and identical DO-204AL package configuration. The substitute provides superior electrical performance with increased power dissipation (2 W) and reduced impedance (60 Ohms).

Compliance Considerations:

The substitute part is RoHS non-compliant, whereas the main part is RoHS3 compliant. Applications subject to RoHS3 regulatory requirements must use the BZX85C62-TAP. The substitute is suitable only for applications where RoHS compliance is not mandated.

Temperature Range Consideration:

The substitute part operates from -65°C to 150°C, while the main part operates from -55°C to 175°C. Applications requiring operation above 150°C must use the BZX85C62-TAP. Applications operating within -55°C to 150°C may use either part.

Frequently Asked Questions (FAQ)

Q: Can the 2EZ62D5/TR8 be used as a direct replacement for the BZX85C62-TAP in all applications?

A: The 2EZ62D5/TR8 is electrically compatible for applications not requiring RoHS3 compliance and operating within the temperature range of -55°C to 150°C. Applications requiring RoHS3 compliance or operation above 150°C must use the BZX85C62-TAP.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are zener voltage (62 V), voltage tolerance (±5%), reverse leakage current (500 nA @ 47 V), and package type (DO-204AL). The substitute must match or exceed power dissipation and impedance specifications.

Q: Are both parts pin-compatible?

A: Yes. Both parts use the DO-204AL (DO-41) axial through-hole package with identical pin configuration and mechanical dimensions, allowing direct board-level substitution without layout modification.

Q: What is the difference in impedance between these parts, and does it affect circuit performance?

A: The BZX85C62-TAP has a maximum impedance of 125 Ohms, while the 2EZ62D5/TR8 has a maximum impedance of 60 Ohms. Lower impedance in the substitute provides improved voltage regulation and faster transient response. This difference is beneficial in most applications.

Q: Why does the substitute part have higher power dissipation capability?

A: The 2EZ62D5/TR8 is rated for 2 W maximum power dissipation compared to 1.3 W for the BZX85C62-TAP. This provides additional thermal margin and allows operation in higher-power applications while maintaining the same zener voltage specification.

Q: What compliance certifications apply to each part?

A: The BZX85C62-TAP carries AEC-Q101 automotive qualification and RoHS3 compliance. The 2EZ62D5/TR8 is RoHS non-compliant and does not carry AEC-Q101 qualification. Both parts are REACH unaffected and classified as EAR99.
