ZMY68-GS18 Equivalent & Substitute Parts

Part Overview

The ZMY68-GS18 is an automotive-grade Zener diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates at a nominal Zener voltage of 68 V with 1 W maximum power dissipation and is packaged in the DO-213AB (MELF) form factor. The device is AEC-Q101 qualified and RoHS3 compliant, making it suitable for automotive applications requiring voltage regulation and transient protection.

The ZMY68-GS18 is currently in active production status with 1055 units in stock. Identifying equivalent substitute parts becomes necessary when the primary part number is unavailable or when alternative packaging configurations are required while maintaining identical electrical performance and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ZMY68-GS18 are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following critical parameters:

Electrical Parameters (Must Match):

• Zener voltage: 68 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 1 W
• Impedance (maximum): 130 Ohms
• Reverse leakage current: 500 nA @ 51 V
• Operating temperature: 175°C

Mechanical & Compliance Parameters (Must Match):

• Package / Case: DO-213AB, MELF (Glass)
• Mounting type: Surface Mount
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Allowed to Differ):

• Packaging configuration: Tape & Reel (TR) or Cut Tape (CT)

The ZMY68-GS18 is supplied in Tape & Reel packaging. Substitute parts may be available in alternative packaging configurations such as Cut Tape, provided all electrical and compliance specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The ZMY68-GS08 is a direct electrical and mechanical equivalent to the ZMY68-GS18. Both parts share identical electrical specifications, including Zener voltage, power rating, impedance, and leakage characteristics. Both components carry automotive-grade qualification (AEC-Q101) and maintain full RoHS3 compliance with MSL 1 rating.

The primary distinction between these parts is the packaging configuration. The ZMY68-GS18 is supplied in Tape & Reel format, while the ZMY68-GS08 is supplied in Cut Tape format. This difference affects only the delivery and handling method; the component itself remains functionally identical.

Selection between these parts should be based on procurement requirements and assembly process compatibility. Tape & Reel packaging is typically used for high-volume automated assembly operations, while Cut Tape packaging is suitable for lower-volume applications or manual assembly processes. Both packaging formats are compatible with standard surface mount assembly equipment when appropriate feeders are employed.

Frequently Asked Questions (FAQ)

Q: Can the ZMY68-GS08 be used as a direct replacement for the ZMY68-GS18 in automotive applications?

A: Yes. The ZMY68-GS08 is electrically and mechanically equivalent to the ZMY68-GS18. Both components meet identical electrical specifications, carry AEC-Q101 automotive qualification, and are RoHS3 compliant. The only difference is the packaging configuration (Cut Tape versus Tape & Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated high-speed pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for lower-volume production or manual assembly. The components themselves are identical; only the delivery format differs.

Q: Are both parts suitable for the same circuit applications?

A: Yes. Both the ZMY68-GS18 and ZMY68-GS08 are 68 V, 1 W Zener diodes with identical electrical characteristics. They are suitable for identical voltage regulation and transient protection applications in automotive circuits.

Q: Do both parts meet the same compliance and qualification standards?

A: Yes. Both parts are AEC-Q101 qualified, RoHS3 compliant, and carry MSL 1 (Unlimited) moisture sensitivity rating. They meet identical automotive-grade requirements.

Q: Which part should be selected for new designs?

A: Selection should be based on manufacturing process requirements. For automated assembly with high-volume production, Tape & Reel packaging (ZMY68-GS18) is standard. For lower-volume or manual assembly processes, Cut Tape packaging (ZMY68-GS08) may be more practical. Both are equally suitable from an electrical and compliance perspective.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts have identical maximum operating temperature (175°C), power dissipation (1 W), and all electrical characteristics. Thermal and performance behavior is identical.
