Substitute Part Grouping Explanation

Substitution of the TZMB13-GS18 is determined by strict equivalence across the following critical parameters:

Zener Voltage (Nominal): 13 V
Voltage Tolerance: ±2%
Maximum Power Dissipation: 500 mW
Maximum Impedance: 26 Ohms
Reverse Leakage Current: 100 nA @ 10 V
Forward Voltage: 1.5 V @ 200 mA
Operating Temperature Range: -65°C to 175°C
Package Type: SOD-80 MiniMELF
Mounting Technology: Surface Mount
Automotive Grade: AEC-Q101 qualified
RoHS Compliance: ROHS3 Compliant

The TZMB13-GS08 qualifies as a parametric equivalent because it maintains identical electrical specifications and automotive qualification. The only difference is the packaging format: TZMB13-GS18 is supplied in Cut Tape (CT), while TZMB13-GS08 is supplied in Tape & Reel (TR). Both parts share the same base product number (TZMB13) and belong to the TZM series.

Engineering Selection Recommendations

Both TZMB13-GS18 and TZMB13-GS08 are active production parts with identical electrical and thermal specifications. Selection between these parts is determined by packaging and supply requirements:

TZMB13-GS18 (Cut Tape): Suitable for applications requiring smaller order quantities or manual assembly processes where individual component handling is necessary.

TZMB13-GS08 (Tape & Reel): Suitable for high-volume automated assembly operations where continuous reel feeding is required. This format provides higher inventory availability (70,000 units in stock).

Both parts maintain full compliance with AEC-Q101 automotive qualification, ROHS3 environmental standards, and REACH regulations. The choice between these substitutes is driven by manufacturing process requirements and supply chain logistics rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can TZMB13-GS08 be used as a direct replacement for TZMB13-GS18 in automotive applications?

A: Yes. Both parts are electrically and mechanically identical, with AEC-Q101 qualification. The only difference is packaging format (Tape & Reel versus Cut Tape). Substitution is valid for any circuit application where the original part was specified.

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

A: Cut Tape (CT) packaging supplies components on tape that is cut into individual strips, typically used for lower-volume orders and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for automated pick-and-place assembly equipment in high-volume production.

Q: Are there any thermal or electrical performance differences between TZMB13-GS18 and TZMB13-GS08?

A: No. Both parts have identical Zener voltage (13 V), power rating (500 mW), impedance (26 Ohms), reverse leakage current (100 nA @ 10 V), forward voltage (1.5 V @ 200 mA), and operating temperature range (-65°C to 175°C).

Q: Do both parts meet automotive qualification standards?

A: Yes. Both TZMB13-GS18 and TZMB13-GS08 are AEC-Q101 qualified automotive-grade components manufactured by Vishay General Semiconductor - Diodes Division.

Q: Which part should be selected for high-volume production?

A: TZMB13-GS08 (Tape & Reel) is recommended for high-volume automated assembly due to its continuous reel format and higher inventory availability (70,000 units in stock versus 25,300 for the Cut Tape version).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both TZMB13-GS18 and TZMB13-GS08 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
