EGP20C Equivalent & Substitute Parts

Part Overview

The EGP20C is a general-purpose rectifier diode manufactured by onsemi, rated for 150 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole axial package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product portfolio. Identification of equivalent and substitute parts is necessary for legacy system maintenance, repair operations, and applications where the EGP20C specification remains functionally appropriate.

Substitute Part Grouping Explanation

Substitution of the EGP20C is determined by the following critical parameters:

Voltage Rating: The reverse voltage (Vr) must equal or exceed 150 V. Parts with higher voltage ratings (165 V, 200 V) are electrically compatible in applications where the EGP20C operates below its maximum rating.

Current Rating: The average rectified current (Io) must equal or exceed 2 A. Parts rated for 1.9 A or lower do not meet the minimum current requirement and are classified as similar but not direct substitutes. Parts rated for 3 A or higher provide margin above the specified requirement.

Forward Voltage (Vf): Forward voltage drop at rated current affects power dissipation and circuit performance. The EGP20C specifies 950 mV @ 2 A. Schottky technology (STPS2150) exhibits lower forward voltage (820 mV @ 2 A), while avalanche diodes (BYT53C, BYV27-150) exhibit higher forward voltage (1.07–1.1 V), reflecting different semiconductor physics.

Package Compatibility: The EGP20C uses DO-15 (DO-204AC) axial through-hole packaging. Direct substitutes must use identical or mechanically compatible packages. SOD-57 packages (BYT53C, BYV27-150) differ in physical form factor and are classified as similar rather than direct substitutes.

Technology Type: The EGP20C uses standard (silicon junction) rectifier technology. Schottky diodes (STPS2150) and avalanche diodes (BYT53C, BYV27-150) employ different semiconductor structures and exhibit different electrical characteristics, particularly in reverse leakage current and forward voltage.

Reverse Recovery Time (trr): The EGP20C specifies 50 ns. Faster recovery (25 ns for BYV27-150) indicates superior high-frequency performance; slower recovery is not acceptable for fast-switching applications.

Engineering Selection Recommendations

Direct Equivalent (Identical Electrical and Physical Specifications):

The EGP20C-E3/54 manufactured by Vishay General Semiconductor - Diodes Division is the direct equivalent. This part maintains identical electrical parameters (150 V, 2 A, 950 mV forward voltage, 50 ns recovery time) and uses the same DO-15 package. The EGP20C-E3/54 carries Active product status and is ROHS3 compliant, making it suitable for applications requiring the exact EGP20C specification. The base product number (EGP20) confirms functional equivalence across the onsemi and Vishay product lines.

Direct Substitutes (Same Package, Equivalent Electrical Performance):

The STPS2150 manufactured by STMicroelectronics is a direct substitute in DO-15 packaging with identical voltage and current ratings. The Schottky technology reduces forward voltage to 820 mV @ 2 A, resulting in lower power dissipation. Reverse leakage current is reduced to 1.5 µA @ 150 V. This part is suitable for applications where reduced forward voltage drop improves efficiency. The STPS2150 is Active and ROHS3 compliant.

Similar Parts (Different Package, Comparable Electrical Performance):

The BYT53C-TAP and BYT53C-TR are avalanche diodes with 150 V rating and 1.9 A current rating in SOD-57 packaging. These parts do not meet the 2 A minimum current requirement and use a different package form factor. They are suitable only for applications where the SOD-57 package is acceptable and current demand does not exceed 1.9 A.

The BYV27-150-TAP and BYV27-150-TR are avalanche diodes with 165 V rating and 2 A current rating in SOD-57 packaging. These parts exceed the voltage requirement and use a different package. They are suitable for applications where higher voltage margin and SOD-57 packaging are acceptable.

The STTH302 and STTH302RL are general-purpose rectifiers with 200 V rating and 3 A current rating in DO-201AD packaging. These parts exceed both voltage and current requirements and use a larger package form factor. They are suitable for applications requiring higher voltage and current margins where the DO-201AD package can be accommodated.

All substitute parts listed carry Active product status and ROHS3 compliance, confirming current manufacturing availability and environmental regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can the EGP20C-E3/54 be used as a direct replacement for the EGP20C?

A: Yes. The EGP20C-E3/54 is electrically and mechanically identical to the EGP20C. Both parts share the same base product number (EGP20), voltage rating (150 V), current rating (2 A), forward voltage (950 mV @ 2 A), recovery time (50 ns), and DO-15 package. The EGP20C-E3/54 is manufactured by Vishay and carries Active product status.

Q: What is the difference between the EGP20C and STPS2150?

A: Both parts use DO-15 packaging and share identical voltage (150 V) and current (2 A) ratings. The primary difference is semiconductor technology: the EGP20C uses standard silicon junction rectifier technology, while the STPS2150 uses Schottky technology. The STPS2150 exhibits lower forward voltage (820 mV vs. 950 mV @ 2 A) and lower reverse leakage current (1.5 µA vs. 5 µA @ 150 V). The STPS2150 is suitable for applications where reduced power dissipation is beneficial.

Q: Why are BYT53C and BYV27-150 listed as similar rather than direct substitutes?

A: The BYT53C series has a current rating of 1.9 A, which falls below the EGP20C requirement of 2 A. The BYV27-150 series uses SOD-57 packaging instead of DO-15, requiring different board layout and mechanical accommodation. Both parts employ avalanche diode technology rather than standard rectifier technology. These differences classify them as similar parts suitable only for applications where the specific package and current rating are acceptable.

Q: Can the STTH302 replace the EGP20C?

A: The STTH302 exceeds the EGP20C specification in voltage (200 V vs. 150 V) and current (3 A vs. 2 A) ratings, making it electrically compatible. However, the STTH302 uses DO-201AD packaging, which is physically larger than the DO-15 package of the EGP20C. Substitution requires verification that the larger package can be accommodated in the circuit board layout. The STTH302 is suitable for applications where higher voltage and current margins are beneficial and package size is not a constraint.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (EGP20C-E3/54, STPS2150, BYT53C-TAP, BYT53C-TR, BYV27-150-TAP, BYV27-150-TR, STTH302, STTH302RL) carry ROHS3 compliance certification, confirming conformance to Restriction of Hazardous Substances regulations.

Q: What is the significance of reverse recovery time (trr) in selecting a substitute?

A: Reverse recovery time determines how quickly the diode transitions from conducting to blocking state when reverse voltage is applied. The EGP20C specifies 50 ns. The BYV27-150 series offers faster recovery at 25 ns, suitable for high-frequency switching applications. The STTH302 specifies 35 ns. Slower recovery times are not acceptable for fast-switching circuits. Forward voltage and reverse leakage current also vary with technology type and affect circuit performance.

Q: What packaging options are available for EGP20C substitutes?

A: Direct substitutes in DO-15 packaging include the EGP20C-E3/54 and STPS2150. Similar parts in SOD-57 packaging include BYT53C-TAP, BYT53C-TR, BYV27-150-TAP, and BYV27-150-TR. The STTH302 and STTH302RL use DO-201AD packaging. Package selection depends on circuit board layout constraints and mechanical accommodation requirements.
