Key Parameters

Substitute Part Grouping Explanation

Substitution in the Zener diode category is confirmed on the basis of strict equivalency in core electrical and mechanical parameters: Zener voltage, tolerance, maximum power rating, maximum impedance, maximum reverse leakage, forward voltage at test current, operating temperature range, qualification grade, package, mounting type, RoHS/REACH compliance, and MSL. Alternate packaging formats are permitted if the functional device parameters, automotive qualification, and compliance certifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both TZMB30-GS18 and TZMB30-GS08 are active products with equivalent electrical, mechanical, and qualification parameters, including automotive grade AEC-Q101, RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity. The only notable distinction is the packaging: TZMB30-GS18 is provided in Tape & Reel (TR), while TZMB30-GS08 is available in Cut Tape (CT) & Digi-Reel®. Selection between these parts may be determined by inventory and packaging preferences, with no impact on performance or compliance.

Frequently Asked Questions (FAQ)

Q: What are the critical substitution criteria for TZMB30-GS18 in Zener diode applications?
A: Substitution is permitted with parts meeting identical Zener voltage, tolerance, power rating, maximum impedance, reverse leakage, forward voltage at test current, operating temperature range, automotive (AEC-Q101) qualification, package, mounting type, and compliance certifications.

Q: Does the difference in packaging format (Tape & Reel vs. Cut Tape/Digi-Reel) affect electrical or mechanical compatibility?
A: Packaging format does not alter the device electrical or mechanical characteristics; compatibility is maintained across both packaging types when core parameters are equal.

Q: Are both part numbers suitable for automotive applications?
A: Both TZMB30-GS18 and TZMB30-GS08 are automotive grade and AEC-Q101 qualified.

Q: How does supplier device package specification influence substitution?
A: As both parts are supplied in SOD-80 MiniMELF (DO-213AC) surface mount packages, substitution preserves all form factor and board assembly requirements.

Q: Are there any differences in compliance, such as RoHS or REACH, between these substitutes?
A: Both parts are RoHS3 compliant and REACH unaffected, ensuring regulatory compatibility.

Q: What moisture sensitivity level (MSL) applies to these Zener diodes?
A: Both are classified at MSL 1 (Unlimited), supporting standard surface-mount assembly processes.
