Substitute Part Grouping Explanation

Substitution of the EGP20K is determined by the following critical parameters:

Voltage Rating: All substitute parts must support a minimum DC reverse voltage of 800 V. Parts rated at 1000 V (BYV38-TAP, BYV38-TR, BYW56-TAP) exceed this requirement and are electrically compatible.

Current Rating: All substitute parts must support a minimum average rectified current of 2 A. All identified substitutes meet this specification.

Package Compatibility: The EGP20K uses a DO-15 (DO-204AC) axial through-hole package. Substitutes in SOD-57 package format (BYV37-TAP, BYV37-TR, BYV38-TAP, BYV38-TR, BYW55-TAP, BYW55-TR, BYW56-TAP) are mechanically compatible as both are axial through-hole configurations. Substitutes maintaining DO-15 packaging (FR206GP-AP, FR206GP-TP, GPP20K-E3/54) provide direct form-factor compatibility.

Technology Classification: The EGP20K uses standard rectifier technology. Avalanche-type diodes (BYV37, BYV38, BYW55, BYW56 series) provide enhanced reverse voltage protection and are functionally compatible. Standard technology substitutes (FR206GP series, GPP20K-E3/54) maintain identical technology classification.

Recovery Speed: The EGP20K features fast recovery characteristics (≤ 500 ns). Substitutes are grouped into fast recovery (BYV37-TAP, BYV37-TR, BYV38-TAP, BYV38-TR, FR206GP-AP, FR206GP-TP) and standard recovery (BYW55-TAP, BYW55-TR, BYW56-TAP, GPP20K-E3/54) categories. Selection depends on application switching frequency requirements.

Engineering Selection Recommendations

Direct Package Replacement (DO-15 Format):

FR206GP-AP and FR206GP-TP maintain identical DO-15 package geometry and are rated for 800 V / 2 A operation. Both are Active status products with ROHS3 compliance. FR206GP-TP is supplied on tape and reel, while FR206GP-AP is supplied on cut tape. These parts are suitable for direct board-level substitution without mechanical modification.

GPP20K-E3/54 is a Vishay general-purpose rectifier in DO-15 format rated for 800 V / 2 A with Active product status and ROHS3 compliance. This part operates with standard recovery characteristics, making it suitable for lower-frequency applications where fast recovery is not required.

Axial Through-Hole Substitutes (SOD-57 Package):

BYV37-TAP and BYV37-TR are Vishay avalanche diodes rated for 800 V / 2 A with fast recovery characteristics and Active status. Both are ROHS3 compliant. The SOD-57 package is mechanically compatible with through-hole mounting but requires PCB layout adjustment due to different lead spacing compared to DO-15.

BYV38-TAP and BYV38-TR are rated for 1000 V / 2 A, providing enhanced voltage margin. Both feature fast recovery and Active status with ROHS3 compliance. These parts are suitable for applications requiring higher reverse voltage capability.

BYW55-TAP and BYW55-TR are Vishay avalanche diodes rated for 800 V / 2 A with standard recovery characteristics. Both are Active status with ROHS3 compliance. These parts feature lower forward voltage (1 V @ 1 A) and reduced reverse leakage (1 µA @ 800 V) compared to the EGP20K.

BYW56-TAP is rated for 1000 V / 2 A with standard recovery characteristics, Active status, and ROHS3 compliance. This part combines higher voltage rating with standard recovery speed and low reverse leakage.

Compliance and Regulatory Status:

All identified substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory status of the EGP20K. All parts carry EAR99 export classification and identical HTSUS commodity codes.

Frequently Asked Questions (FAQ)

Q: Can I use a 1000 V rated diode (BYV38, BYW56) in place of the 800 V EGP20K?

A: Yes. A higher voltage rating is electrically compatible. The 1000 V parts (BYV38-TAP, BYV38-TR, BYW56-TAP) will operate correctly in circuits designed for 800 V operation. The higher voltage rating provides additional reverse voltage margin without affecting forward conduction characteristics.

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

A: Recovery speed refers to reverse recovery time (trr). The EGP20K has a trr of 75 ns (fast recovery ≤ 500 ns). BYV37 and BYV38 series have trr of 300 ns. BYW55 and BYW56 series have trr of 4 µs (standard recovery > 500 ns). Fast recovery diodes are required for high-frequency switching applications. Standard recovery diodes are suitable for lower-frequency rectification and power supply applications.

Q: Can I substitute a SOD-57 package diode for a DO-15 package diode?

A: Both packages are axial through-hole configurations and are mechanically compatible for through-hole mounting. However, SOD-57 and DO-15 have different lead spacing and physical dimensions. PCB layout modification is required. If direct form-factor compatibility is required without PCB redesign, use FR206GP-AP, FR206GP-TP, or GPP20K-E3/54, which maintain DO-15 packaging.

Q: What is the difference between cut tape (CT/TAP) and tape & reel (TR) packaging?

A: Cut tape packaging supplies components in individual strips suitable for manual assembly or small-volume production. Tape & reel packaging supplies components on continuous reels suitable for automated assembly equipment. Both packaging formats contain identical components; the difference is in supply format and handling method.

Q: Why is the EGP20K marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status at the manufacturer. onsemi no longer recommends this part for new circuit designs. Existing applications may continue to use available inventory, but new designs should select from Active status alternatives such as FR206GP-TP, GPP20K-E3/54, or Vishay BYV37/BYV38/BYW55/BYW56 series.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, matching the regulatory status of the EGP20K. All parts are also REACH unaffected.

Q: What is the significance of forward voltage (Vf) differences between parts?

A: Forward voltage affects power dissipation and heat generation during conduction. The EGP20K has Vf of 1.7 V @ 2 A. Substitute parts range from 1.0 V to 1.3 V @ rated current. Lower forward voltage reduces power loss and heat generation. Selection depends on thermal design requirements and circuit efficiency specifications.

Q: Can I use GPP20K-E3/54 as a direct replacement for EGP20K?

A: GPP20K-E3/54 is a general-purpose rectifier with identical voltage and current ratings (800 V / 2 A) in the same DO-15 package. However, it operates with standard recovery characteristics (> 500 ns) compared to the EGP20K's fast recovery (≤ 500 ns). This substitution is suitable for low-frequency rectification applications but not for high-frequency switching circuits.
