PR3005G-T Equivalent & Substitute Parts

Part Overview

The PR3005G-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 600 V DC reverse voltage and 3 A average rectified current in a DO-201AD axial through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design requirements and procurement needs. The diode features fast recovery characteristics with a reverse recovery time of 250 ns, making it suitable for applications requiring rapid switching performance.

Substitute Part Grouping Explanation

Substitution of the PR3005G-T is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 3 A minimum
Mounting Type: Through Hole
Package / Case: DO-201AD or equivalent axial configuration

Performance Considerations:

Speed classification (Fast Recovery vs. Standard Recovery) affects switching applications
Reverse recovery time (trr) influences high-frequency performance
Forward voltage (Vf) impacts power dissipation and thermal characteristics
Reverse leakage current affects standby power consumption

Compliance Factors:

RoHS3 compliance status for regulatory adherence
REACH status for supply chain continuity
Product status (Active vs. Obsolete vs. Not For New Designs) for long-term availability

Substitute parts are grouped into two categories: Direct Equivalents (matching all critical parameters including speed classification) and Functional Alternatives (meeting voltage and current ratings with different speed characteristics or package variants).

Engineering Selection Recommendations

Direct Equivalent (Preferred for Fast Recovery Applications):

The RGP30J-E3/54 from Vishay General Semiconductor is the closest direct equivalent to the PR3005G-T. It matches all critical electrical parameters including 600 V reverse voltage, 3 A average rectified current, 1.3 V forward voltage at 3 A, and fast recovery characteristics with 250 ns reverse recovery time. The RGP30J-E3/54 is active in production, ROHS3 compliant, and offers an extended operating temperature range (-65°C to 175°C) compared to the original part. This part is available in Cut Tape packaging with 18,712 units in stock.

Alternative for Standard Recovery Applications:

The 1N5406-E3/54 from Vishay General Semiconductor provides a functional alternative when fast recovery performance is not required. It maintains the 600 V / 3 A rating and DO-201AD package but operates with standard recovery characteristics (>500ns). This part is active, ROHS3 compliant, and offers superior forward voltage performance (1.2 V @ 3 A). The operating temperature range is -50°C to 150°C.

Alternatives with Different Package Configurations:

The 1N5190 and 1N5420 from Microchip Technology are fast recovery equivalents with 600 V / 3 A ratings but use the B axial package instead of DO-201AD. Both are active and support extended temperature ranges (-65°C to 175°C). However, both are RoHS non-compliant, which may restrict use in regulated applications. The 1N5190 has 946 units in stock, while the 1N5420 has 1,308 units available.

Higher Current Rating Option:

The 60S6-TP from Micro Commercial Co provides a 600 V / 6 A rated diode in the DO-201AD package. This part is suitable for applications requiring higher current capacity while maintaining the same package footprint. It is active, ROHS3 compliant, and has 5,572 units in stock.

Not Recommended for New Designs:

The 1N5406RLG from onsemi is marked "Not For New Designs" despite being active in inventory. While it meets the 600 V / 3 A specifications, its status restricts use in new product development.

Frequently Asked Questions (FAQ)

Q: Can the RGP30J-E3/54 directly replace the PR3005G-T without circuit modifications?

A: Yes. The RGP30J-E3/54 is a direct electrical equivalent with identical voltage, current, and recovery time specifications. The only difference is an extended maximum junction temperature (175°C vs. 150°C), which provides additional thermal margin. No circuit modifications are required.

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

A: Fast recovery diodes (≤500ns reverse recovery time) switch off more rapidly, reducing switching losses in high-frequency applications. Standard recovery diodes (>500ns) are suitable for lower-frequency rectification where switching speed is less critical. The PR3005G-T uses fast recovery technology with 250 ns trr. Substitutes like the 1N5406 series use standard recovery and may not perform identically in high-frequency circuits.

Q: Why are some substitutes marked RoHS non-compliant?

A: The 1N5190 and 1N5420 from Microchip Technology are RoHS non-compliant, meaning they may contain restricted substances such as lead. These parts are suitable only for applications and markets where RoHS compliance is not mandated. For regulated industries or EU markets, ROHS3 compliant alternatives must be selected.

Q: Can I use the 60S6-TP (6 A rated) in place of the PR3005G-T (3 A rated)?

A: Yes, the 60S6-TP can be used as a substitute from an electrical standpoint. It maintains the 600 V reverse voltage rating and DO-201AD package but provides double the current capacity. This is a conservative substitution suitable for applications where higher current margin is beneficial. However, verify that the circuit design does not depend on the specific 3 A current rating.

Q: What packaging options are available for substitutes?

A: Most substitutes use the DO-201AD axial package, which is mechanically and electrically compatible with the original PR3005G-T. The 1N5190 and 1N5420 use the B axial package, which is also a through-hole axial configuration but with different physical dimensions. Verify PCB footprint compatibility before selecting these alternatives. The RGP30J-E3/54 is available in Cut Tape (CT) packaging, while other variants offer Tape & Reel (TR) or Tape & Box (TB) options.

Q: Which substitute offers the best forward voltage performance?

A: The 1N5406-G from Comchip Technology and 1N5406RLG from onsemi both offer 1.0 V forward voltage at 3 A, which is lower than the PR3005G-T (1.3 V @ 3 A). Lower forward voltage reduces power dissipation and heat generation. However, these parts use standard recovery characteristics, which may not be suitable for fast-switching applications.

Q: Is the RGP30J-E3/54 available in different packaging formats?

A: The RGP30J-E3/54 is specified as available in Cut Tape (CT) packaging. For different packaging requirements (Tape & Reel, Bulk, or Tape & Box), alternative part numbers from the same manufacturer or other suppliers should be evaluated based on specific procurement needs.

Q: What is the REACH status and why does it matter?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a European Union regulation governing chemical substances. The RGP30J-E3/54 is REACH Unaffected, meaning it complies with REACH requirements. The PR3005G-T is REACH Affected, which may indicate supply chain considerations for EU applications. For European markets, REACH Unaffected parts are preferred.
