RS3000-TP Equivalent & Substitute Parts

Part Overview

The RS3000-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 3000 V DC reverse voltage with 200 mA average rectified current in a DO-41 through-hole package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part operates across a junction temperature range of -55°C to 150°C and is RoHS3 compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS3000-TP is determined by the following critical electrical and mechanical parameters:

Voltage Rating Equivalence: The substitute part must maintain the 3000 V DC reverse voltage specification to ensure equivalent reverse breakdown protection.

Current Rating Compatibility: The substitute part current rating must equal or exceed the 200 mA average rectified current requirement. A higher current rating (250 mA) is acceptable as it provides additional design margin without compromising circuit function.

Package Compatibility: Both the main part and substitute must use through-hole mounting with DO-41 or DO-204AL (equivalent) axial package geometry to ensure mechanical and electrical compatibility with existing PCB layouts.

Reverse Leakage Specification: The substitute part must maintain the 5 µA reverse leakage current specification at 3000 V to ensure equivalent leakage performance.

Temperature Range: The substitute part operating temperature range must encompass or exceed the original -55°C to 150°C specification.

Compliance Status: Both parts must maintain RoHS3 compliance for regulatory equivalence.

The GI250-3-E3/54 meets all substitution criteria and is classified as an active product with enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The RS3000-TP is obsolete, while the GI250-3-E3/54 is actively manufactured and supported. For new designs or ongoing production requiring component replenishment, the GI250-3-E3/54 provides assured long-term availability and supply chain continuity.

Compliance Alignment: Both parts maintain ROHS3 compliance, ensuring regulatory equivalence for applications subject to RoHS directives.

Electrical Performance: The GI250-3-E3/54 maintains identical reverse voltage (3000 V) and reverse leakage (5 µA @ 3000 V) specifications. The higher current rating (250 mA versus 200 mA) and lower forward voltage drop (3.5 V @ 250 mA versus 4 V @ 500 mA) represent performance enhancements. The lower junction capacitance (3 pF versus 30 pF) may affect high-frequency switching characteristics in specific circuit topologies.

Temperature Range: The GI250-3-E3/54 extends the operating temperature range to -65°C to 175°C, providing additional thermal margin beyond the original -55°C to 150°C specification.

Packaging and Mechanical Compatibility: Both parts use identical through-hole DO-41 axial packaging, ensuring direct PCB layout compatibility without modification.

Frequently Asked Questions (FAQ)

Q: Can the GI250-3-E3/54 directly replace the RS3000-TP in existing designs?

A: Yes. Both parts share identical reverse voltage (3000 V), reverse leakage (5 µA @ 3000 V), through-hole mounting type, and DO-41 axial package geometry. The substitute part's higher current rating (250 mA) and extended temperature range provide additional design margin.

Q: What is the significance of the different speed classifications?

A: The RS3000-TP is classified as small signal with any speed, while the GI250-3-E3/54 is standard recovery with reverse recovery time of 2 µs. In applications requiring fast switching or high-frequency operation, the GI250-3-E3/54's defined recovery time may provide more predictable performance. In low-frequency rectification applications, both classifications are functionally equivalent.

Q: Does the lower capacitance of the GI250-3-E3/54 affect circuit performance?

A: The GI250-3-E3/54 capacitance is 3 pF compared to 30 pF for the RS3000-TP. In high-frequency or high-impedance circuits, lower capacitance may reduce parasitic effects. In standard rectification applications, this difference is not significant. Circuit-specific analysis is required for applications sensitive to junction capacitance.

Q: Are there packaging differences between these parts?

A: Both parts use DO-41 axial through-hole packaging. The RS3000-TP is supplied in standard packaging, while the GI250-3-E3/54 is available in tape and reel format. The physical component dimensions and PCB footprint are identical.

Q: Why is the GI250-3-E3/54 preferred for new applications?

A: The GI250-3-E3/54 is actively manufactured and supported by Vishay, ensuring long-term availability and supply chain reliability. The RS3000-TP is obsolete and subject to limited inventory and potential discontinuation. For ongoing production or new designs, the active product provides superior procurement assurance.

Q: What is the impact of the higher current rating on circuit design?

A: The GI250-3-E3/54 is rated for 250 mA average rectified current compared to 200 mA for the RS3000-TP. This higher rating provides additional thermal and electrical margin in the same package. Existing designs operating at or below 200 mA require no modification.
