ZPY68-TR Zener Diode Equivalent & Substitute Parts

Part Overview

The ZPY68-TR is an automotive-grade Zener diode manufactured by Vishay General Semiconductor - Diodes Division. This component is rated for 68 V nominal Zener voltage with 1.3 W maximum power dissipation in a DO-41 through-hole package. The part is supplied in Tape & Reel (TR) packaging format and maintains Active product status with full AEC-Q101 automotive qualification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging format preferences while maintaining identical functional specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ZPY68-TR is determined by the following critical parameters:

Electrical Equivalence Requirements:

Zener voltage rating: 68 V nominal
Voltage tolerance: ±5%
Maximum power dissipation: 1.3 W
Operating temperature range: 175°C maximum

Mechanical Compatibility Requirements:

Package type: DO-204AL (DO-41) axial through-hole configuration
Mounting method: Through-hole insertion

Compliance & Qualification Requirements:

Automotive grade classification
AEC-Q101 qualification
ROHS3 compliance
REACH unaffected status

The substitute part 1N4760A-TAP meets all electrical and mechanical requirements for direct substitution. The primary difference is packaging format (Cut Tape versus Tape & Reel) and minor variations in secondary electrical characteristics that remain within acceptable operational parameters for this component category.

Engineering Selection Recommendations

Both ZPY68-TR and 1N4760A-TAP are Active product status components manufactured by Vishay General Semiconductor - Diodes Division with identical automotive-grade classification and AEC-Q101 qualification. Both components satisfy ROHS3 compliance and REACH unaffected requirements for regulated applications.

Selection between these parts is determined by packaging and supply requirements:

ZPY68-TR (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel-fed component dispensing.

1N4760A-TAP (Cut Tape): Suitable for lower-volume applications, manual assembly processes, or situations where smaller quantity increments are required.

Both parts deliver equivalent electrical performance within the specified 68 V Zener voltage rating and 1.3 W power dissipation envelope. The DO-41 through-hole package format is identical, ensuring mechanical interchangeability in PCB designs. Secondary electrical parameters including impedance and reverse leakage current variations remain within acceptable operational tolerances for automotive-grade Zener diode applications.

Frequently Asked Questions (FAQ)

Q: Can 1N4760A-TAP replace ZPY68-TR in production assemblies?

A: Yes. Both components share identical electrical specifications (68 V nominal Zener voltage, ±5% tolerance, 1.3 W maximum power), mechanical package format (DO-41 through-hole), and automotive qualifications (AEC-Q101). The primary difference is packaging format (Cut Tape versus Tape & Reel), which affects supply chain logistics but not functional performance.

Q: What is the significance of the impedance difference (65 Ohms versus 150 Ohms)?

A: Impedance variation is a secondary electrical characteristic that occurs within normal manufacturing tolerances for Zener diodes. Both values remain within acceptable ranges for 68 V Zener diode applications. This parameter does not affect substitution eligibility for standard voltage regulation and transient protection circuits.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ZPY68-TR and 1N4760A-TAP carry automotive-grade classification and AEC-Q101 qualification, confirming suitability for automotive electronic systems. Both maintain ROHS3 compliance and REACH unaffected status for regulated markets.

Q: Does the reverse leakage current difference affect circuit performance?

A: Reverse leakage current variation (500 nA versus 5 µA) is within normal manufacturing tolerances for Zener diodes and does not impact substitution eligibility. Both values are acceptable for standard voltage regulation and protection applications.

Q: What packaging format should be selected for my application?

A: Tape & Reel (TR) format is optimized for high-volume automated assembly with continuous component dispensing. Cut Tape (CT) format is suitable for lower-volume manual assembly or applications requiring smaller quantity increments. Electrical and mechanical performance are identical.
