ZMS2800TA Schottky Diode Equivalent & Substitute Parts

Part Overview

The ZMS2800TA is an RF Schottky diode manufactured by Diodes Incorporated, rated for 70V peak reverse voltage with 250mW power dissipation in SOD-323 surface mount packaging. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part maintains electrical compatibility within defined parameter ranges while offering improved availability and compliance status through active alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZMS2800TA is determined by the following mandatory parameters:

• Voltage - Peak Reverse (Max): Must equal or exceed 70V
• Diode Type: Must be Schottky - Single
• Package / Case: Must be SOD-323
• Capacitance @ Vr, F: Must equal 2pF @ 0V, 1MHz
• Current rating: Must support minimum 15mA operation

The substitute parts listed below meet these electrical and mechanical requirements. Differences in power dissipation rating, operating temperature range, and product status are noted but do not preclude functional substitution when application requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

1N5711WS-7-F is the primary substitute from Diodes Incorporated, maintaining manufacturer continuity. This part is active, ROHS3 compliant, and carries identical voltage and capacitance specifications. The reduced power dissipation rating (150mW vs. 250mW) requires thermal analysis for applications operating at maximum power levels. Operating temperature maximum is reduced to 125°C, which may impact high-temperature applications.

1PS76SB70,115 and 1PS76SB70,135 are functionally equivalent alternatives from Nexperia USA Inc. Both parts meet voltage, capacitance, and package requirements. These parts support higher average rectified current (70mA vs. 15mA), providing additional design margin. Both are ROHS3 compliant and rated to 150°C junction temperature. The primary distinction is packaging format: 1PS76SB70,115 is supplied in Cut Tape & Digi-Reel format, while 1PS76SB70,135 is supplied in Tape & Reel format.

Selection should prioritize active, ROHS3-compliant parts for new designs. Thermal and current requirements of the specific application determine whether the 1N5711WS-7-F or Nexperia alternatives are appropriate.

Frequently Asked Questions (FAQ)

Q: Can the ZMS2800TA be directly replaced with 1N5711WS-7-F?

A: Yes, within thermal constraints. Both parts share identical voltage (70V), current (15mA), and capacitance (2pF @ 0V, 1MHz) specifications in SOD-323 packaging. The 1N5711WS-7-F has lower power dissipation (150mW vs. 250mW) and reduced maximum operating temperature (125°C vs. 150°C). Applications must confirm thermal performance remains acceptable.

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

A: Both parts are electrically identical. The difference is packaging format only: 1PS76SB70,115 is supplied in Cut Tape & Digi-Reel format, while 1PS76SB70,135 is supplied in Tape & Reel format. Selection depends on assembly line requirements and inventory management preferences.

Q: Are all substitute parts RoHS compliant?

A: Yes. The ZMS2800TA is RoHS non-compliant (obsolete status). All three substitute parts—1N5711WS-7-F, 1PS76SB70,115, and 1PS76SB70,135—are ROHS3 compliant, meeting current regulatory requirements.

Q: Can I use the Nexperia parts if my design specifies Diodes Incorporated components?

A: Electrical and mechanical compatibility is confirmed. However, design specifications requiring single-source manufacturer qualification must be evaluated separately. Both manufacturers provide equivalent performance within the specified parameter ranges.

Q: What happens if my application requires the full 250mW power dissipation of the original ZMS2800TA?

A: The 1N5711WS-7-F is rated for 150mW maximum. The Nexperia alternatives (1PS76SB70,115 and 1PS76SB70,135) do not specify power dissipation limits but support higher average rectified current (70mA). Thermal modeling is required to confirm suitability for high-power applications.
