ES1JE-TP Equivalent & Substitute Parts

Part Overview

The ES1JE-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 1 A average rectified current in a surface mount DO-214AC (SMAE) package. This part is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design requirements and production continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter tolerances for 600 V, 1 A rectifier applications.

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

ES1J-LTP (Micro Commercial Co) is the direct equivalent replacement for ES1JE-TP. Both parts share the same base product number (ES1J), identical voltage and current ratings (600 V, 1 A), and equivalent fast recovery speed classification. ES1J-LTP is currently in active production status with extended operating temperature range (-65°C to 175°C versus -50°C to 150°C) and improved reverse recovery time (35 ns versus 75 ns). The forward voltage specification is slightly higher (1.7 V versus 1.35 V @ 1 A), which remains within acceptable tolerance for general-purpose rectifier applications. ES1J-LTP is available in standard Cut Tape and Digi-Reel packaging with significantly higher inventory availability (55,300 units).

Active Production Alternatives (Fast Recovery):

RS1J-13-F (Diodes Incorporated) and RS1J (Taiwan Semiconductor Corporation) provide fast recovery alternatives with 250 ns reverse recovery time and 1.3 V forward voltage specification. Both maintain 600 V, 1 A ratings and DO-214AC SMA packaging. RS1J-13-F offers extended temperature range (-65°C to 150°C) and is actively produced with high inventory (151,735 units).

CGRA4005-G (Comchip Technology) delivers fast recovery performance with the lowest forward voltage specification (1.1 V @ 1 A) among active alternatives, though reverse recovery time data is not provided. Operating temperature range is -55°C to 150°C.

Active Production Alternatives (Standard Recovery):

GF1J-E3/67A (Vishay General Semiconductor - Diodes Division) is an active production part with standard recovery characteristics (2 µs reverse recovery time), 1.1 V forward voltage, and extended temperature range (-65°C to 175°C). This part uses DO-214BA package instead of DO-214AC, requiring PCB layout verification for mechanical compatibility.

Obsolete/Legacy Parts (Not Recommended for New Designs):

GF1J (onsemi), MRA4005T1G (onsemi), MRA4005T3G (onsemi), and NRVA4005T3G (onsemi) are designated "Not For New Designs" and should not be selected for new product development, though they remain available in inventory for legacy system support.

Compliance & Certification:

All listed parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. ES1J (HY Electronic) carries AEC-Q101 automotive qualification and REACH Affected status. NRVA4005T3G (onsemi) carries AEC-Q101 automotive qualification. Selection should account for application-specific compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can ES1J-LTP directly replace ES1JE-TP without circuit modification?

A: ES1J-LTP is electrically compatible as a direct substitute. Both parts meet 600 V, 1 A specifications and fast recovery speed classification. The forward voltage difference (1.7 V versus 1.35 V @ 1 A) is within typical tolerance for general-purpose rectifier circuits. Verify that the application does not depend on the specific 75 ns reverse recovery time of the original part; ES1J-LTP provides faster recovery at 35 ns, which is generally beneficial. Package compatibility requires confirmation: ES1JE-TP uses DO-214AC (SMAE) while ES1J-LTP uses DO-214AC (SMA), which are mechanically equivalent surface mount packages.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes (≤ 500ns reverse recovery time) exhibit reduced switching losses and are suitable for high-frequency switching applications. Standard recovery diodes (> 500ns reverse recovery time) are appropriate for line-frequency rectification and lower-speed applications. ES1JE-TP is specified as fast recovery (75 ns). Substitution with standard recovery alternatives (GF1J, MRA4005 series) is acceptable only if the application does not require fast switching performance.

Q: Are DO-214AC and DO-214BA packages interchangeable?

A: DO-214AC (SMA) and DO-214BA (GF1) are distinct surface mount packages with different mechanical dimensions and PCB footprints. While both are surface mount diode packages, they are not directly interchangeable without PCB redesign. GF1J-E3/67A uses DO-214BA package and requires footprint verification before substitution.

Q: Which substitute part offers the best availability?

A: MRA4005T3G (onsemi) and MRA4005T1G (onsemi) provide the highest inventory levels (820,400 and 820,300 units respectively), though both are designated "Not For New Designs." For active production parts, ES1J-LTP (55,300 units) and RS1J-13-F (151,735 units) offer substantial availability.

Q: Does forward voltage variation affect circuit performance?

A: Forward voltage differences between 1.0 V and 1.7 V @ 1 A are typical across the 600 V, 1 A rectifier family. In power supply and general rectification circuits, this variation produces minimal impact on output voltage regulation. In precision analog circuits or low-voltage applications, forward voltage variation may require circuit analysis. The ES1JE-TP specification of 1.35 V @ 1 A falls within the middle of the substitute range.

Q: What is the significance of reverse leakage current specification?

A: Reverse leakage current (Ir) is specified at maximum reverse voltage (600 V). ES1JE-TP and most substitutes specify 5 µA @ 600 V, while MRA4005 series parts specify 10 µA @ 600 V. Higher leakage current increases power dissipation in reverse bias conditions and may affect high-impedance circuit performance. For standard rectifier applications, this difference is negligible.

Q: Are automotive-qualified alternatives available?

A: ES1J (HY Electronic) carries AEC-Q101 automotive qualification with fast recovery characteristics (35 ns) and 1.7 V forward voltage. NRVA4005T3G (onsemi) also carries AEC-Q101 qualification with standard recovery characteristics (2 µs) and 1.1 V forward voltage. Selection depends on application speed requirements and temperature range compatibility.

Q: What packaging options are available for substitutes?

A: ES1JE-TP is supplied in tape form (packaging not specified). Substitute parts are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel (ES1J-LTP, RS1J, GF1J-E3/67A), Tape & Reel (TR) (CGRA4005-G, GF1J, MRA4005T1G, MRA4005T3G, NRVA4005T3G, RS1J-13-F). Packaging selection affects handling, storage, and assembly process compatibility.
