Engineering Selection Recommendations

Direct Current Rating Match (2 A):

GPP20M-E3/54 is a direct functional equivalent to the 2A07G A0G, offering identical voltage and current ratings with matching package specifications. Both components maintain the same operating temperature range (-55°C to 150°C) and standard recovery characteristics. This part is recommended for direct replacement in applications where the original specification is maintained.

HER208G-TP provides 2 A current capacity with identical reverse voltage rating and operating temperature range. This part features fast recovery characteristics (75 ns) compared to the standard recovery of the 2A07G A0G, resulting in higher forward voltage (1.7 V @ 2 A). Selection of HER208G-TP is appropriate for applications requiring reduced reverse recovery time, provided forward voltage dissipation is acceptable.

Lower Current Rating (1.5 A):

GP15M-E3/54 and GP15M-E3/73 are rated for 1.5 A average rectified current with extended operating temperature range (-65°C to 175°C). These parts are suitable for applications where current requirements do not exceed 1.5 A and extended temperature operation is beneficial. Forward voltage is reduced to 1.1 V @ 1.5 A compared to the main part.

1N5399GP-E3/54 and 1N5399GP-E3/73 are rated for 1.5 A with extended temperature range (-65°C to 175°C). These parts feature standard recovery characteristics and are suitable for lower current applications.

RGP15M-E3/54 is rated for 1.5 A with fast recovery characteristics (500 ns) and extended temperature range (-65°C to 175°C). This part is appropriate for applications requiring reduced reverse recovery time at lower current levels.

Lower Current Rating (1 A):

BYV26EGP-E3/54 and BYV26EGP-E3/73 are rated for 1 A average rectified current with fast recovery characteristics (75 ns) and extended operating temperature range (-65°C to 175°C). These parts are suitable only for applications with maximum current requirements of 1 A.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and identical reverse leakage specifications (5 µA @ 1000 V). All parts are classified as Active product status.

Frequently Asked Questions (FAQ)

Q: Can GPP20M-E3/54 be used as a direct replacement for 2A07G A0G?

A: Yes. GPP20M-E3/54 matches all critical parameters: 1000 V reverse voltage, 2 A average rectified current, DO-204AC package, through-hole mounting, and -55°C to 150°C operating temperature range. Forward voltage is slightly higher (1.1 V vs. 1 V @ 2 A), which is acceptable in most applications.

Q: What is the difference between HER208G-TP and the main part 2A07G A0G?

A: HER208G-TP features fast recovery characteristics (75 ns reverse recovery time) compared to standard recovery (>500 ns) in the 2A07G A0G. This results in higher forward voltage (1.7 V @ 2 A vs. 1 V @ 2 A). Fast recovery reduces switching losses in high-frequency applications but increases conduction losses. Both parts are rated for 1000 V, 2 A, and -55°C to 150°C.

Q: Can 1.5 A rated diodes be used in place of the 2 A rated 2A07G A0G?

A: 1.5 A rated diodes (GP15M-E3/54, GP15M-E3/73, 1N5399GP-E3/54, 1N5399GP-E3/73, RGP15M-E3/54) are suitable only if the application current requirement does not exceed 1.5 A. These parts provide extended operating temperature range (-65°C to 175°C) compared to the main part. Exceeding the rated current causes excessive heat generation and component failure.

Q: What is the advantage of extended temperature range parts?

A: Parts with -65°C to 175°C operating range (GP15M, 1N5399GP, RGP15M, BYV26EGP series) provide design margin for applications operating at temperature extremes. The main part 2A07G A0G is limited to -55°C to 150°C. Extended range parts are beneficial for industrial, automotive, or aerospace applications with wide ambient temperature variation.

Q: Are there differences between E3/54 and E3/73 packaging variants?

A: E3/54 and E3/73 designations indicate different tape and reel configurations for automated assembly. Both variants of the same part number (e.g., GP15M-E3/54 and GP15M-E3/73) have identical electrical specifications and package dimensions. Selection between variants depends on assembly equipment compatibility and supply chain availability.

Q: What does "fast recovery" mean and when is it required?

A: Fast recovery (≤500 ns) refers to reduced reverse recovery time, which is the time required for the diode to stop conducting when reverse bias is applied. Fast recovery reduces switching losses in high-frequency rectification circuits (typically above 10 kHz). Standard recovery (>500 ns) is suitable for line-frequency (50/60 Hz) and low-frequency applications. BYV26EGP and HER208G-TP feature fast recovery; other parts feature standard recovery.

Q: Is the 1 A rated BYV26EGP-E3/73 suitable for my 2 A application?

A: No. BYV26EGP-E3/73 is rated for maximum 1 A average rectified current. Operating at 2 A exceeds the rated current and causes excessive junction temperature rise, leading to thermal runaway and component failure. Use only parts rated for 2 A or higher current capacity.

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

A: All listed parts specify 5 µA @ 1000 V reverse leakage current, indicating identical leakage characteristics. This parameter is critical in high-impedance circuits where leakage current affects circuit performance. The matching specification across all parts ensures equivalent behavior in leakage-sensitive applications.

Q: Can I use HER208G-TP if my circuit operates at frequencies below 1 kHz?

A: Yes. HER208G-TP is suitable for any frequency application, including DC and low-frequency rectification. The fast recovery characteristic (75 ns) provides no disadvantage at low frequencies; it simply reduces switching losses that are negligible at low frequencies. Forward voltage (1.7 V @ 2 A) is the primary consideration for low-frequency applications.
