EGP30C Equivalent & Substitute Parts

Part Overview

The EGP30C is a general-purpose rectifier diode manufactured by onsemi, rated for 150 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This device is classified as Last Time Buy, indicating discontinued production status. The part operates across a junction temperature range of -65°C to 150°C and features fast recovery characteristics with a 50 ns reverse recovery time. Identification of equivalent and substitute parts is necessary due to the Last Time Buy status, which restricts future availability of the original component.

Substitute Part Grouping Explanation

Substitute parts for the EGP30C are classified into two categories based on electrical parameter alignment:

Similar Manufacturer Parts maintain the same voltage rating (150 V) and current rating (3 A or higher) with identical or superior fast recovery characteristics. These parts are direct functional replacements within the same electrical specification envelope.

Parametric Equivalent Parts match all critical electrical parameters (150 V reverse voltage, 3 A average rectified current, 950 mV forward voltage drop, fast recovery speed) while originating from different manufacturers. These parts satisfy identical circuit requirements.

Substitution eligibility is determined by the following criteria:

Voltage - DC Reverse (Vr) rating equal to or greater than 150 V
Current - Average Rectified (Io) rating equal to or greater than 3 A
Voltage - Forward (Vf) compatible with circuit design specifications
Fast Recovery speed classification maintained
DO-201AD axial through-hole package compatibility

Engineering Selection Recommendations

SBYV28-150-E3/54 (Vishay General Semiconductor - Diodes Division) is a similar manufacturer part with Active product status. This part maintains the 150 V reverse voltage rating and exceeds the 3 A current requirement at 3.5 A. The forward voltage specification increases to 1.1 V at 3.5 A, which represents a measurable change in circuit behavior. Reverse recovery time improves to 20 ns. Operating temperature range is -55°C to 150°C, which is narrower at the lower bound compared to the EGP30C. RoHS3 compliance is maintained.

STTH302 and STTH302RL (STMicroelectronics) are similar manufacturer parts with Active product status. Both parts increase the reverse voltage rating to 200 V while maintaining the 3 A current rating. Forward voltage remains at 950 mV at 3 A, matching the EGP30C specification. Reverse recovery time improves to 35 ns. Maximum junction temperature increases to 175°C. RoHS3 compliance is maintained. STTH302RL is the tape-and-reel variant of STTH302.

SF33G-TP (Micro Commercial Co) is a parametric equivalent part with Active product status. This part matches the EGP30C across all critical electrical parameters: 150 V reverse voltage, 3 A current rating, 950 mV forward voltage, and fast recovery speed. Reverse recovery time is 35 ns. Operating temperature range is -65°C to 150°C, identical to the EGP30C. RoHS3 compliance is maintained.

All substitute parts maintain RoHS3 compliance and fast recovery speed classification. Selection between substitutes depends on circuit requirements for voltage margin, temperature operating range, and reverse recovery time performance.

Frequently Asked Questions (FAQ)

Q: Can STTH302 or STTH302RL be used in place of EGP30C?

A: Yes. Both STTH302 and STTH302RL meet or exceed the electrical requirements of the EGP30C. The 200 V reverse voltage rating provides additional voltage margin beyond the 150 V specification. Forward voltage drop remains identical at 950 mV at 3 A. Both parts are in Active product status and RoHS3 compliant. The primary consideration is the increased maximum junction temperature (175°C vs. 150°C), which may affect thermal design calculations in high-temperature applications.

Q: What is the difference between STTH302 and STTH302RL?

A: STTH302RL is the tape-and-reel packaging variant of STTH302. Both parts are electrically identical with the same electrical specifications, reverse voltage rating, current rating, and fast recovery characteristics. The packaging difference affects handling and automated assembly processes only.

Q: Is SBYV28-150-E3/54 a direct replacement for EGP30C?

A: SBYV28-150-E3/54 is functionally compatible with the EGP30C for most applications. Both parts share the 150 V reverse voltage rating and fast recovery speed classification. The SBYV28-150-E3/54 provides higher current capacity at 3.5 A versus 3 A. Forward voltage increases to 1.1 V at 3.5 A, which represents a 150 mV increase in voltage drop compared to the EGP30C at 3 A. Operating temperature range is narrower at the lower bound (-55°C vs. -65°C). These differences require circuit-level evaluation for applications with tight thermal or voltage drop budgets.

Q: Does SF33G-TP provide identical electrical performance to EGP30C?

A: SF33G-TP is a parametric equivalent to EGP30C. Both parts share identical specifications for reverse voltage (150 V), average rectified current (3 A), forward voltage (950 mV at 3 A), and operating temperature range (-65°C to 150°C). Reverse recovery time is 35 ns for SF33G-TP versus 50 ns for EGP30C, representing improved switching performance. Both parts are RoHS3 compliant and use the DO-201AD axial through-hole package.

Q: Are all substitute parts available in the same DO-201AD package?

A: Yes. All substitute parts listed (SBYV28-150-E3/54, STTH302, STTH302RL, and SF33G-TP) use the DO-201AD axial through-hole package with identical mechanical dimensions and mounting characteristics. Direct mechanical substitution is supported without PCB layout modifications.

Q: What is the significance of the Last Time Buy status for EGP30C?

A: Last Time Buy status indicates that onsemi has discontinued production of the EGP30C. This classification restricts future availability and establishes a final order deadline. Transition to an Active product status substitute part is necessary for long-term supply chain continuity. All listed substitute parts maintain Active product status with ongoing manufacturer support.

Q: How do reverse recovery time differences affect circuit performance?

A: Reverse recovery time (trr) determines the switching speed of the diode during the transition from forward to reverse bias. EGP30C has a trr of 50 ns. Substitute parts offer improved performance: SBYV28-150-E3/54 at 20 ns, STTH302/STTH302RL at 35 ns, and SF33G-TP at 35 ns. Faster recovery times reduce switching losses and electromagnetic interference in high-frequency applications. Circuits designed for the EGP30C will function with faster recovery diodes without performance degradation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (SBYV28-150-E3/54, STTH302, STTH302RL, and SF33G-TP) are RoHS3 compliant, matching the compliance status of the EGP30C. REACH status is Unaffected for all parts.
