ZMY11-GS08 Equivalent & Substitute Parts

Part Overview

The ZMY11-GS08 is an 11V 1W Zener diode manufactured by Vishay General Semiconductor - Diodes Division in DO-213AB surface mount package. This component is classified as an automotive-grade Zener diode with AEC-Q101 qualification and is currently in active production status. Zener diodes are essential voltage regulation and protection components in electronic circuits. Finding equivalent substitute parts becomes necessary due to supply chain constraints, inventory availability, or specific packaging requirements while maintaining identical electrical performance and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ZMY11-GS08 are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Zener (Nominal): 11 V
• Tolerance: ±5%
• Power - Maximum: 1 W
• Package / Case: DO-213AB, MELF (Glass)
• Mounting Type: Surface Mount
• Operating Temperature: 175°C
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents. Variations in secondary parameters such as impedance (Zzt) and reverse leakage current remain within acceptable ranges for the same voltage and power classification and do not affect substitutability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The ZM4741A-GS08 is a direct electrical and mechanical equivalent to the ZMY11-GS08. Both components share identical voltage regulation characteristics (11V nominal), power dissipation capability (1W maximum), and automotive-grade qualification (AEC-Q101). Both maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

The primary distinction between these parts is packaging format: ZMY11-GS08 is supplied in Cut Tape (CT) format, while ZM4741A-GS08 is supplied in Tape & Reel (TR) format. This difference affects only procurement and assembly logistics, not electrical performance or functional compatibility.

Both components are active products with current manufacturing status and full inventory availability. Selection between these parts should be based on packaging requirements and supply chain availability rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can ZM4741A-GS08 be used as a direct replacement for ZMY11-GS08?

A: Yes. Both parts are identical in electrical specifications, voltage rating (11V), power rating (1W), tolerance (±5%), operating temperature (175°C), and automotive qualification (AEC-Q101). The only difference is packaging format (Cut Tape versus Tape & Reel).

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies components in individual strips cut to specific lengths, suitable for smaller volume orders or manual assembly. Tape & Reel packaging supplies components on continuous reels, optimized for high-volume automated assembly. Both formats contain identical components with no electrical differences.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ZMY11-GS08 and ZM4741A-GS08 carry automotive-grade classification and AEC-Q101 qualification, meeting automotive industry reliability and quality standards.

Q: Do these parts have identical reverse leakage characteristics?

A: Both parts meet the same automotive and AEC-Q101 standards. Reverse leakage specifications differ slightly (500 nA @ 8.5V for ZMY11-GS08 versus 5 µA @ 8.4V for ZM4741A-GS08), but both values are within acceptable ranges for 11V Zener diodes in this power class and do not affect functional substitutability.

Q: Are both parts RoHS compliant?

A: Yes. Both ZMY11-GS08 and ZM4741A-GS08 are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: Can I mix these parts in the same assembly?

A: Yes. Both parts are electrically and mechanically equivalent. Mixing is permissible from a technical standpoint, though assembly process parameters may require adjustment based on packaging format differences.
