RHRP3060 Equivalent & Substitute Parts

Part Overview

The RHRP3060 is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 30 A average rectified current in a through-hole TO-220-2L package. Manufactured by onsemi, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. Substitute diodes must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Substitute Part Grouping Explanation

Substitution of the RHRP3060 is determined by the following critical parameters:

Primary Electrical Requirements:

Voltage - DC Reverse (Vr) (Max): minimum 600 V
Current - Average Rectified (Io): minimum 30 A
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Electrical Characteristics:

Voltage - Forward (Vf) (Max) @ If: acceptable range 1.61 V to 2.52 V @ 30 A
Reverse Recovery Time (trr): acceptable range 30 ns to 75 ns
Current - Reverse Leakage @ Vr: acceptable range 40 µA to 250 µA @ 600 V

Mechanical & Environmental Requirements:

Mounting Type: Through Hole
Package / Case: TO-220-2 or TO-220-2 Insulated
Operating Temperature - Junction: minimum -55°C to maximum 175°C
RoHS Status: ROHS3 Compliant

Substitute parts meeting these criteria are grouped by current rating and forward voltage characteristics. Parts with 30 A current rating and 600 V voltage rating are direct substitutes. Parts with higher current ratings (40 A) or higher voltage ratings (650 V) are acceptable upgrades. Parts with lower current ratings (5 A, 10 A, 12 A, 15 A, 20 A) are not suitable substitutes for the 30 A requirement.

Engineering Selection Recommendations

Direct Substitutes (600 V, 30 A Rating):

The following parts are direct electrical and mechanical substitutes for the RHRP3060:

DSEP29-06A (IXYS): Active product with superior forward voltage performance (1.61 V @ 30 A). Faster reverse recovery time (35 ns). Identical voltage and current ratings. TO-220-2 package compatible with TO-220-2L footprint. ROHS3 compliant. Recommended for applications prioritizing efficiency.
DSEP29-06B (IXYS): Active product with faster reverse recovery time (30 ns). Forward voltage within acceptable range (2.52 V @ 30 A). Identical voltage and current ratings. TO-220-2 package compatible. ROHS3 compliant.
DTH3006D (Diodes Incorporated): Active product with matching reverse recovery time (45 ns) to original part. Forward voltage 2.4 V @ 30 A. Lower reverse leakage current (100 µA @ 600 V). TO-220-2 package compatible. ROHS3 compliant. Recommended for applications requiring low leakage characteristics.
PSDP3060S1_T0_00001 (Panjit International Inc.): Active product with 600 V, 30 A rating. Forward voltage 2.3 V @ 30 A. Operating temperature maximum 150°C (lower than original 175°C). TO-220-2 package compatible. ROHS3 compliant. Suitable for applications with thermal headroom.

Upgraded Substitute (650 V, 40 A Rating):

IDP40E65D2XKSA1 (Infineon Technologies): Active product with higher voltage rating (650 V) and higher current rating (40 A). Forward voltage 2.3 V @ 40 A. Longer reverse recovery time (75 ns). TO-220-2 package. ROHS3 compliant. Suitable for applications requiring higher performance margins or future design upgrades.

Non-Recommended Parts:

STTH30R06CW is a diode array with 15 A per diode rating and TO-247-3 package. Current rating is insufficient for 30 A requirement and package is incompatible with TO-220-2 footprint. Not suitable as substitute.

Lower current-rated parts (DHG5I600PA, DHG10I600PA, DHG20I600PA, STTH12R06DIRG) do not meet the 30 A current requirement and are not suitable substitutes.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the RHRP3060?

A: Yes. The IDP40E65D2XKSA1 with 650 V rating is acceptable. Higher voltage ratings provide additional safety margin in reverse voltage conditions. This is an upgrade path suitable for new designs.

Q: What is the difference between DSEP29-06A and DSEP29-06B?

A: Both are 600 V, 30 A IXYS diodes in TO-220-2 package. DSEP29-06A has lower forward voltage (1.61 V @ 30 A) and faster recovery time (35 ns), resulting in lower power dissipation. DSEP29-06B has higher forward voltage (2.52 V @ 30 A) but faster recovery time (30 ns). Selection depends on thermal and efficiency requirements.

Q: Is the TO-220-2L package compatible with TO-220-2 package footprints?

A: Yes. TO-220-2L and TO-220-2 are mechanically compatible through-hole packages with identical lead spacing and mounting hole patterns. Both accommodate standard TO-220 mounting hardware.

Q: Why is DTH3006D recommended for low-leakage applications?

A: DTH3006D has reverse leakage current of 100 µA @ 600 V, compared to 250 µA @ 600 V for the RHRP3060. Lower leakage reduces standby power consumption in applications with extended idle periods or high-impedance circuits.

Q: Can I use PSDP3060S1_T0_00001 in applications requiring operation above 150°C?

A: No. PSDP3060S1_T0_00001 has maximum junction temperature of 150°C, compared to 175°C for the RHRP3060. Applications requiring sustained operation above 150°C require alternative parts with higher temperature ratings, such as DSEP29-06A, DSEP29-06B, DTH3006D, or IDP40E65D2XKSA1.

Q: What is the advantage of the IDP40E65D2XKSA1 upgrade?

A: The IDP40E65D2XKSA1 provides 40 A current capacity and 650 V voltage rating, exceeding the RHRP3060 specifications. This upgrade is suitable for future design iterations requiring higher power handling or additional voltage margin. All electrical and mechanical parameters remain compatible with TO-220-2 mounting.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts listed carry ROHS3 Compliant certification, matching the compliance status of the RHRP3060.

Q: Which substitute part has the lowest forward voltage drop?

A: DSEP29-06A has the lowest forward voltage at 1.61 V @ 30 A, resulting in the lowest power dissipation and heat generation during operation. This characteristic is advantageous in high-current applications where thermal management is critical.
