ES1ME-TP Equivalent & Substitute Parts

Part Overview

The ES1ME-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 1 A average rectified current in a DO-214AC (SMA) surface mount package. This part is classified as obsolete, indicating it has been discontinued and is no longer recommended for new designs. Identifying equivalent and substitute parts is necessary to maintain supply chain continuity for existing applications and to transition designs to active, supported alternatives that meet the same electrical and mechanical requirements.

Substitute Part Grouping Explanation

Substitution of the ES1ME-TP is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 1000 V minimum
Current - Average Rectified (Io): 1 A minimum
Mounting Type: Surface Mount
Package / Case: DO-214AC or DO-214BA (both SMA-compatible form factors)

Acceptable Variation Parameters:

Voltage - Forward (Vf): Substitute parts may have lower forward voltage (improved efficiency)
Reverse Recovery Time (trr): Substitute parts may have faster or slower recovery characteristics
Operating Temperature Range: Substitute parts may have extended temperature ranges
Product Status: Active parts are preferred over obsolete or not-for-new-designs classifications

Substitute parts are grouped into two categories:

Direct Equivalents (Same Voltage, Current, Package): Parts meeting all mandatory parameters with DO-214AC packaging and 1000 V / 1 A ratings.

Functional Equivalents (Same Voltage, Current, Compatible Package): Parts meeting voltage and current requirements but using DO-214BA packaging or alternative manufacturers, maintaining electrical compatibility while offering improved product status or performance characteristics.

Engineering Selection Recommendations

Primary Recommendation: US1M-TP

US1M-TP is the preferred direct substitute for ES1ME-TP. Both parts are manufactured by Micro Commercial Co and share identical electrical ratings (1000 V, 1 A) and packaging (DO-214AC). US1M-TP is classified as Active, ensuring continued availability and manufacturer support. The part exhibits improved forward voltage characteristics (1.4 V @ 2 A versus 1.7 V @ 1 A) and maintains the same fast recovery speed (≤ 500ns) and reverse recovery time (100 ns). Operating temperature range is extended (-65°C to 175°C versus -50°C to 150°C). RoHS3 compliance and unlimited moisture sensitivity level are maintained.

Secondary Recommendation: CGRA4007-G

CGRA4007-G by Comchip Technology meets all mandatory electrical parameters (1000 V, 1 A) and uses the same DO-214AC package. This part is Active and RoHS3 compliant. Forward voltage is reduced to 1.1 V @ 1 A, providing improved efficiency. Recovery speed is standard (>500ns) rather than fast, which is acceptable for general-purpose applications where switching speed is not critical.

Tertiary Recommendation: GF1M-E3/67A or GF1M-E3/5CA

These Vishay General Semiconductor parts (SUPERECTIFIER® series) meet the 1000 V, 1 A electrical requirements and are Active products. Both use DO-214BA packaging, which is mechanically compatible with DO-214AC in surface mount applications. Forward voltage is 1.2 V @ 1 A. Recovery speed is standard (>500ns). GF1M-E3/67A is supplied in Tape & Reel packaging; GF1M-E3/5CA is supplied in Cut Tape & Digi-Reel®. Both offer extended operating temperature ranges (-65°C to 175°C).

Alternative for Higher Current Applications: HS2MA

HS2MA by Good-Ark Semiconductor is rated for 1000 V and 1.5 A (exceeding the 1 A requirement). It uses DO-214AC packaging and is Active. This part is suitable for applications requiring current margin or future design upgrades. Fast recovery speed (≤ 500ns) and 75 ns reverse recovery time are maintained.

Not Recommended for New Designs:

GF1M (onsemi) and MRA4007T3G (onsemi) are classified as "Not For New Designs" and should be avoided for new applications, although they remain electrically compatible with ES1ME-TP.

Frequently Asked Questions (FAQ)

Q: Can US1M-TP directly replace ES1ME-TP without circuit modification?

A: Yes. US1M-TP is a direct substitute with identical voltage (1000 V), current (1 A), and package (DO-214AC) ratings. The improved forward voltage (1.4 V @ 2 A) and extended temperature range (-65°C to 175°C) provide enhanced performance without requiring circuit changes.

Q: What is the difference between DO-214AC and DO-214BA packages?

A: Both are surface mount packages for general-purpose rectifier diodes. DO-214AC (SMA) and DO-214BA (GF1) are mechanically and electrically compatible in most applications. The primary difference is the physical form factor and manufacturer convention. Parts using either package can be substituted if electrical parameters match.

Q: Why do some substitute parts have lower forward voltage than ES1ME-TP?

A: Forward voltage variation is a normal characteristic of diode manufacturing and design. Lower forward voltage (such as 1.1 V or 1.2 V versus 1.7 V) indicates improved efficiency and reduced power dissipation. This is a beneficial characteristic and does not prevent substitution.

Q: Can I use GF1K-E3/67A (800 V) instead of ES1ME-TP (1000 V)?

A: No. GF1K-E3/67A is rated for 800 V maximum reverse voltage, which is below the 1000 V requirement of ES1ME-TP. Using an 800 V part in a 1000 V application creates a reliability risk and is not acceptable.

Q: What does "Fast Recovery ≤ 500ns" mean compared to "Standard Recovery >500ns"?

A: Recovery speed refers to how quickly the diode transitions from conducting to blocking state. Fast recovery (≤ 500ns) is beneficial in high-frequency switching applications. Standard recovery (>500ns) is acceptable for general-purpose rectification and lower-frequency applications. Both are suitable for most standard rectifier applications.

Q: Is MRA4007T3G a suitable substitute?

A: MRA4007T3G meets the electrical requirements (1000 V, 1 A, DO-214AC package) but is classified as "Not For New Designs" by onsemi. While electrically compatible, it is not recommended for new applications. US1M-TP or CGRA4007-G are preferred alternatives with Active product status.

Q: Can I use HS2MA (1.5 A) in place of ES1ME-TP (1 A)?

A: Yes. HS2MA is rated for 1.5 A, which exceeds the 1 A requirement of ES1ME-TP. The higher current rating provides design margin and is electrically compatible. This substitution is suitable for applications where additional current capacity is beneficial or anticipated.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended substitute parts (US1M-TP, CGRA4007-G, GF1M-E3/67A, GF1M-E3/5CA, GF1M/1754, HS2MA) are RoHS3 compliant. GF1M/1754 is the only exception, marked as RoHS non-compliant. For applications requiring RoHS compliance, avoid GF1M/1754.

Q: What is the significance of "Moisture Sensitivity Level (MSL): 1 (Unlimited)"?

A: MSL 1 indicates unlimited shelf life and no special moisture protection requirements during storage or handling. All listed substitute parts share this characteristic, ensuring compatibility with standard component storage and assembly processes.
