Key Parameters

Substitute Part Grouping Explanation

Substitution of the R3000-TP is based on matching the following critical electrical and mechanical parameters:

Voltage Rating: Both the main part and substitute maintain identical 3000 V DC reverse voltage specification, ensuring equivalent reverse bias capability.

Current Rating: The substitute part GI250-3-E3/54 is rated for 250 mA average rectified current, which exceeds the R3000-TP requirement of 200 mA, providing operational margin within the same voltage class.

Package Type: Both components utilize through-hole axial mounting in DO-15/DO-204AL package families, ensuring mechanical and electrical compatibility in existing PCB layouts.

Reverse Leakage: Identical 5 µA reverse leakage current at 3000 V specification confirms equivalent leakage characteristics.

Compliance: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), satisfying regulatory and environmental requirements.

Temperature Range: The substitute part extends the upper junction temperature limit to 175°C compared to the R3000-TP at 150°C, providing enhanced thermal margin.

Engineering Selection Recommendations

The GI250-3-E3/54 from Vishay General Semiconductor - Diodes Division is a direct substitute for the obsolete R3000-TP. Selection of this substitute is supported by the following factors:

Electrical Equivalence: Identical 3000 V reverse voltage and 5 µA reverse leakage current at rated voltage ensure equivalent electrical performance in high-voltage rectification applications.

Current Margin: The 250 mA rating of the substitute exceeds the 200 mA requirement of the original part, providing operational headroom without derating.

Active Product Status: The GI250-3-E3/54 maintains active product status with established supply chain availability (17110 pcs in stock), addressing the obsolescence of the R3000-TP.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical moisture sensitivity classification, ensuring no change in procurement or assembly requirements.

Temperature Performance: Extended operating range (-65°C to 175°C) of the substitute provides enhanced thermal capability compared to the original specification (-55°C to 150°C).

Package Compatibility: Both components utilize standard through-hole axial packages (DO-15/DO-204AL), permitting direct PCB layout substitution without redesign.

Frequently Asked Questions (FAQ)

Q: Can the GI250-3-E3/54 be used as a direct replacement for the R3000-TP in existing designs?

A: Yes. Both parts share identical 3000 V reverse voltage rating, 5 µA reverse leakage specification, and through-hole axial package configuration. The substitute's higher 250 mA current rating and extended temperature range provide additional design margin.

Q: What is the difference between DO-15 and DO-204AL packages?

A: DO-15 and DO-204AL are equivalent axial through-hole package designations for diodes. DO-204AL is the formal JEDEC designation, while DO-15 is an alternate industry reference. Both packages are mechanically and electrically compatible for PCB mounting.

Q: Does the lower forward voltage of the GI250-3-E3/54 (3.5 V vs. 4 V) affect circuit performance?

A: The forward voltage specifications are measured at different current levels (250 mA for the substitute vs. 500 mA for the original). At equivalent operating currents within the 200 mA design point, forward voltage characteristics are comparable. Lower forward voltage in the substitute reduces power dissipation.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and identical REACH and ECCN classifications. No compliance differences exist between the original and substitute.

Q: What is the significance of the extended temperature range in the substitute part?

A: The GI250-3-E3/54 operates to 175°C junction temperature compared to 150°C for the R3000-TP. This extended range provides thermal margin in high-temperature applications and reduces the risk of thermal derating in marginal thermal environments.

Q: Is the substitute part available in the same packaging format (Tape & Reel)?

A: The GI250-3-E3/54 is supplied in Tape & Reel (TR) packaging, which is standard for production assembly. The R3000-TP packaging format was not specified in the original data. Tape & Reel format is compatible with automated assembly equipment.
