ZPY62-TAP Equivalent & Substitute Parts

Part Overview

The ZPY62-TAP is a Zener diode rated at 62 V nominal voltage with 1.3 W maximum power dissipation, manufactured by Vishay General Semiconductor - Diodes Division. This through-hole component is packaged in DO-204AL (DO-41) axial configuration and is qualified to AEC-Q101 automotive standards. The part is currently active in production with 677 pieces in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application-specific requirements, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of Zener diodes is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

Voltage - Zener (Nom): Must be 62 V
Tolerance: Must be ±5%
Package / Case: Must be DO-204AL (DO-41) axial through-hole
Mounting Type: Must be through-hole

Allowable Variation Parameters:

Power - Max: Substitute may equal or exceed 1.3 W
Impedance (Max): Substitute may differ within acceptable circuit design margins
Current - Reverse Leakage @ Vr: Substitute may differ
Operating Temperature: Substitute must support minimum 175°C or application-specific requirement

The identified substitutes meet the critical matching parameters. Variations in power rating, impedance, and leakage current are acceptable provided the application circuit design accommodates these differences.

Engineering Selection Recommendations

1N4759A-TAP (Vishay General Semiconductor)

This substitute maintains full electrical and mechanical compatibility with the ZPY62-TAP. Both parts are manufactured by Vishay, carry AEC-Q101 automotive qualification, and are ROHS3 compliant. The 1N4759A-TAP exhibits higher impedance (125 Ohms vs. 60 Ohms) and higher reverse leakage current (5 µA vs. 500 nA), which must be evaluated within the specific circuit application. The part is available in Cut Tape packaging with higher inventory (1131 pieces). Selection of this substitute is appropriate for applications where impedance variation and leakage current differences are acceptable.

2EZ62D5/TR8 (Microsemi Corporation)

This substitute provides equivalent zener voltage and tolerance with increased power rating (2 W vs. 1.3 W). The impedance and reverse leakage current match the ZPY62-TAP specification. However, this part is not AEC-Q101 qualified, is not automotive grade, is RoHS non-compliant, and has a reduced maximum operating temperature of 150°C compared to 175°C. Selection of this substitute is restricted to non-automotive applications where RoHS compliance is not required and the lower operating temperature limit is acceptable. The part offers the highest inventory availability (3193 pieces).

Frequently Asked Questions (FAQ)

Q: Can the 1N4759A-TAP be used as a direct replacement for the ZPY62-TAP?

A: The 1N4759A-TAP is mechanically and electrically compatible for the critical parameters: 62 V nominal voltage, ±5% tolerance, DO-204AL (DO-41) package, and through-hole mounting. Both parts are AEC-Q101 qualified and ROHS3 compliant. The higher impedance (125 Ohms) and reverse leakage current (5 µA) must be verified against circuit design requirements.

Q: What are the key differences between the 1N4759A-TAP and 2EZ62D5/TR8?

A: Both substitutes maintain the 62 V nominal voltage and ±5% tolerance. The 1N4759A-TAP is automotive qualified (AEC-Q101) and ROHS3 compliant with 175°C operating temperature. The 2EZ62D5/TR8 offers higher power rating (2 W) but lacks automotive qualification, is RoHS non-compliant, and has a maximum operating temperature of 150°C.

Q: Is the 2EZ62D5/TR8 suitable for automotive applications?

A: No. The 2EZ62D5/TR8 is not AEC-Q101 qualified and is not designated as automotive grade. It is RoHS non-compliant and has a maximum operating temperature of 150°C, which is below the ZPY62-TAP specification of 175°C. This part is suitable only for non-automotive applications where these limitations are acceptable.

Q: What packaging differences exist between these parts?

A: The ZPY62-TAP is supplied in Tape & Box (TB) packaging. Both substitutes (1N4759A-TAP and 2EZ62D5/TR8) are supplied in Cut Tape (CT) packaging. All three parts use the same DO-204AL (DO-41) axial through-hole package configuration.

Q: How do impedance differences affect substitution?

A: The ZPY62-TAP and 2EZ62D5/TR8 both specify 60 Ohms maximum impedance. The 1N4759A-TAP specifies 125 Ohms maximum impedance. Higher impedance affects transient response and voltage regulation characteristics. Circuit design must accommodate this difference or the 1N4759A-TAP is not suitable.

Q: Are all three parts RoHS compliant?

A: The ZPY62-TAP and 1N4759A-TAP are ROHS3 compliant. The 2EZ62D5/TR8 is RoHS non-compliant. Selection must account for end-product RoHS compliance requirements.
