ZMS2800TC Equivalent & Substitute Parts

Part Overview

The ZMS2800TC is a Schottky diode manufactured by Diodes Incorporated, rated for 70V peak reverse voltage with 250mW power dissipation in SOD-323 packaging. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The part operates across a junction temperature range of -55°C to 150°C and is ROHS3 compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ZMS2800TC is based on strict electrical and mechanical compatibility criteria. The substitute parts must meet the following requirements:

• Schottky diode technology with single junction configuration
• Peak reverse voltage rating of 70V or higher
• SOD-323 package compatibility (SC-76)
• Capacitance specification of 2pF @ 0V, 1MHz
• ROHS3 compliance and MSL 1 rating
• Operating temperature range supporting -55°C to 150°C

The identified substitutes (1PS76SB70,115 and 1PS76SB70,135) are manufactured by Nexperia USA Inc. and meet all electrical and mechanical parameters. Both parts are active products with higher current ratings (70mA average rectified current) and improved availability compared to the obsolete ZMS2800TC.

Parameter Comparison

Engineering Selection Recommendations

Both 1PS76SB70,115 and 1PS76SB70,135 are direct functional equivalents to the ZMS2800TC. The primary distinction between these substitutes is packaging format: 1PS76SB70,115 is supplied in Cut Tape (CT) & Digi-Reel® format, while 1PS76SB70,135 is supplied in Tape & Reel (TR) format. Selection between these two should be based on procurement and assembly requirements rather than electrical performance.

The Nexperia substitutes offer superior product lifecycle status (active vs. obsolete), ensuring long-term availability and supply chain stability. Both parts maintain full ROHS3 compliance and MSL 1 rating, meeting environmental and reliability standards equivalent to the original ZMS2800TC. The higher current rating (70mA vs. 15mA) of the substitutes provides additional design margin without compromising performance in applications designed for the original part.

Frequently Asked Questions (FAQ)

Q: Can 1PS76SB70,115 and 1PS76SB70,135 be used interchangeably with ZMS2800TC?

A: Yes. Both parts meet the electrical specifications (70V reverse voltage, 2pF capacitance @ 0V/1MHz) and mechanical requirements (SOD-323 package) of the ZMS2800TC. The difference between the two Nexperia parts is packaging format only.

Q: What is the difference between 1PS76SB70,115 and 1PS76SB70,135?

A: Both parts are electrically identical. The 1PS76SB70,115 is supplied in Cut Tape (CT) & Digi-Reel® packaging, while 1PS76SB70,135 is supplied in Tape & Reel (TR) packaging. Selection depends on assembly line requirements and volume needs.

Q: Why is the ZMS2800TC obsolete?

A: The ZMS2800TC is classified as obsolete by the manufacturer. The Nexperia 1PS76SB70 series provides equivalent functionality with active product status, ensuring continued availability and support.

Q: Are there any thermal or reliability differences between the original and substitute parts?

A: Both the ZMS2800TC and substitute parts support identical maximum junction temperatures (150°C) and maintain MSL 1 (unlimited) moisture sensitivity ratings. Thermal and reliability performance are equivalent.

Q: Can the substitute parts handle higher currents than the original ZMS2800TC?

A: The substitute parts are rated for 70mA average rectified current compared to the ZMS2800TC's 15mA maximum. In applications designed for the original 15mA specification, the higher rating of the substitutes provides additional design margin without adverse effects.

Q: Are compliance certifications maintained with the substitute parts?

A: Yes. Both 1PS76SB70,115 and 1PS76SB70,135 maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification identical to the ZMS2800TC.
