ES1K-TP General Purpose Rectifier Diode 800V 1A DO-214AC Equivalent & Substitute Parts

Part Overview

The ES1K-TP is a general purpose rectifier diode manufactured by Micro Commercial Co, rated for 800V DC reverse voltage and 1A average rectified current in a surface mount DO-214AC (HSMA) package. This component is classified as Obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The fast recovery characteristic (≤500ns) and 75ns reverse recovery time position this diode for applications requiring rapid switching performance in rectification circuits.

Substitute Part Grouping Explanation

Substitution of the ES1K-TP is determined by the following critical parameters:

Voltage Rating Compatibility: The primary substitution criterion is DC reverse voltage rating. Parts rated at 800V are direct substitutes. Parts rated at 1000V (higher voltage rating) are acceptable substitutes as they provide equivalent or superior voltage withstand capability.

Current Rating: All substitute parts must support 1A average rectified current or higher.

Package Type: Surface mount packages DO-214AC (SMA) and DO-214BA (GF1) are mechanically compatible for board-level substitution, though DO-214BA represents a different physical form factor.

Recovery Characteristics: The ES1K-TP exhibits fast recovery (≤500ns, 75ns trr). Substitutes with standard recovery characteristics (>500ns) represent functional alternatives where switching speed requirements are less stringent.

Forward Voltage: Forward voltage drop ranges from 1.1V to 1.7V across substitute options, affecting power dissipation characteristics.

Temperature Range: Operating junction temperature range varies from -50°C to 175°C across the substitute portfolio.

Product Status and Compliance: RoHS3 compliance and REACH unaffected status are maintained across all active substitute options.

Engineering Selection Recommendations

Direct Voltage and Current Match (800V, 1A):

The US1K-TP from Micro Commercial Co provides electrical equivalence to the ES1K-TP with identical voltage, current, and recovery characteristics. The primary difference is extended operating temperature range (-65°C to 175°C versus -50°C to 150°C) and DO-214AC (SMA) package designation. However, US1K-TP carries "Not For New Designs" status, limiting its suitability for new development.

The CGRA4006-G from Comchip Technology matches the 800V/1A specification with Active product status, making it suitable for new designs. Forward voltage is reduced to 1.1V, resulting in lower power dissipation. Fast recovery characteristic is maintained.

The RGF1K from onsemi provides 800V/1A rating with fast recovery and Active-equivalent status ("Not For New Designs" indicates mature product). Extended temperature range (-65°C to 175°C) and 8.5pF capacitance specification are provided.

Higher Voltage Rating Substitutes (1000V, 1A):

Parts rated at 1000V reverse voltage (GF1M, GF1M-E3/5CA, GF1M-E3/67A, GF1M/1754, MRA4007T3G, NRVA4007T3G) provide superior voltage margin for 800V applications. These substitutes transition to standard recovery characteristics (>500ns, 2µs trr), which is acceptable where fast switching is not critical.

GF1M-E3/5CA and GF1M-E3/67A from Vishay General Semiconductor are Active products with 1000V rating and standard recovery. Both use DO-214BA (GF1) package, requiring PCB layout modification from the original DO-214AC footprint.

MRA4007T3G from onsemi maintains DO-214AC (SMA) package compatibility with 1000V rating and standard recovery. Product status is "Not For New Designs."

NRVA4007T3G from onsemi is automotive-qualified (AEC-Q101) with 1000V rating, standard recovery, and DO-214AC (SMA) package. Operating temperature range is -55°C to 150°C.

Package Considerations:

DO-214AC (SMA) package substitutes (US1K-TP, CGRA4006-G, GF1M, MRA4007T3G, NRVA4007T3G, RGF1K) provide direct PCB footprint compatibility with the ES1K-TP.

DO-214BA (GF1) package substitutes (GF1K-E3/67A, GF1M-E3/5CA, GF1M-E3/67A, GF1M/1754) require PCB layout modification but offer Vishay SUPERECTIFIER® series performance.

Compliance and Regulatory:

All Active and "Not For New Designs" substitutes maintain ROHS3 compliance and REACH unaffected status. GF1M/1754 is RoHS non-compliant, limiting its use in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 1000V rated diode in place of the 800V ES1K-TP?

A: Yes. A 1000V rated diode provides superior voltage withstand capability and is electrically compatible with 800V circuit requirements. The higher voltage rating does not degrade performance in 800V applications.

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

A: The ES1K-TP exhibits fast recovery with 75ns reverse recovery time. Standard recovery substitutes (GF1M series, MRA4007T3G, NRVA4007T3G) have 2µs reverse recovery time. Fast recovery diodes switch more rapidly, reducing switching losses in high-frequency applications. Standard recovery diodes are suitable for lower-frequency rectification where switching speed is not critical.

Q: Can I substitute a DO-214BA package diode for a DO-214AC package diode?

A: DO-214BA and DO-214AC are different physical packages. PCB footprints are not compatible without layout modification. However, electrical performance is equivalent. GF1K-E3/67A and GF1M series parts use DO-214BA packaging and require new PCB design.

Q: What does "Not For New Designs" product status mean?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and recommends alternative parts for new applications. These parts remain available for existing designs and maintenance. For new development, Active status parts (CGRA4006-G, GF1K-E3/67A, GF1M-E3/5CA, GF1M-E3/67A, GF1M/1754) are preferred.

Q: How does forward voltage affect my circuit?

A: Forward voltage (Vf) determines voltage drop across the diode during conduction. The ES1K-TP has Vf of 1.7V at 1A. Substitutes range from 1.1V to 1.3V, resulting in lower power dissipation and reduced heat generation. Lower forward voltage improves circuit efficiency.

Q: Is the NRVA4007T3G automotive-qualified?

A: Yes. NRVA4007T3G carries AEC-Q101 automotive qualification, suitable for automotive and harsh environment applications requiring enhanced reliability screening.

Q: What is the significance of reverse leakage current?

A: Reverse leakage current (Ir) is the small current flowing through the diode when reverse biased. The ES1K-TP specifies 5µA at 800V. Substitutes range from 5µA to 10µA. Lower leakage current reduces standby power consumption and improves circuit efficiency in low-current applications.

Q: Can I use CGRA4006-G as a direct replacement?

A: Yes. CGRA4006-G from Comchip Technology matches the 800V/1A specification, maintains fast recovery characteristics, and carries Active product status. Forward voltage is reduced to 1.1V, improving efficiency. DO-214AC (SMA) package provides direct PCB compatibility.

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

A: Tape & Reel (TR) and Cut Tape (CT) are supply formats for automated assembly. Both contain the same component in the same package. Tape & Reel is continuous reel format for high-volume production. Cut Tape is pre-cut for lower-volume or mixed-component assembly. Electrical performance is identical.

Q: Should I consider temperature range when selecting a substitute?

A: Yes. The ES1K-TP operates from -50°C to 150°C junction temperature. Substitutes offer ranges from -55°C to 175°C. If your application operates at temperature extremes, verify the substitute's temperature range meets requirements. Extended range substitutes provide design margin for thermal stress conditions.
