Key Parameters

Substitute Part Grouping Explanation

Substitution of the R3000-AP is determined by equivalence in the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must maintain the 3000 V DC reverse voltage specification to ensure dielectric integrity in the application circuit.

Current Rating: The substitute part current rating must equal or exceed the 200 mA average rectified current requirement. The GI250-3-E3/54 provides 250 mA, which satisfies this criterion with margin.

Package and Mounting: Both the main part and substitute must use through-hole axial mounting in compatible packages (DO-15 and DO-204AL/DO-41 are mechanically compatible axial configurations).

Reverse Leakage: The substitute maintains the 5 µA reverse leakage specification at 3000 V, ensuring equivalent leakage performance.

Temperature Range: The substitute operating temperature range (-65°C to 175°C) encompasses the main part range (-55°C to 150°C), providing equivalent or superior thermal performance.

Compliance: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

The GI250-3-E3/54 is a direct substitute for the obsolete R3000-AP based on the following engineering criteria:

Electrical Equivalence: Both diodes maintain identical 3000 V reverse voltage and 5 µA reverse leakage specifications. The substitute's 250 mA current rating exceeds the 200 mA requirement, providing operational margin without derating concerns.

Compliance and Certification: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity, ensuring equivalent environmental and regulatory compliance. The substitute carries REACH Unaffected status, providing additional regulatory clarity.

Product Availability: The R3000-AP is obsolete with no ongoing manufacturing. The GI250-3-E3/54 is actively produced by Vishay, ensuring long-term supply chain continuity and availability for production quantities.

Package Compatibility: The DO-204AL (DO-41) package of the substitute is mechanically compatible with the DO-15 axial configuration, allowing direct board-level substitution without layout modification.

Thermal Performance: The substitute's extended operating temperature range (-65°C to 175°C) provides superior thermal margin compared to the main part (-55°C to 150°C).

Frequently Asked Questions (FAQ)

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

A: Yes. Both diodes share identical 3000 V reverse voltage and 5 µA reverse leakage specifications. The substitute's higher 250 mA current rating accommodates the 200 mA requirement with operational margin. Axial through-hole packages are mechanically compatible.

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

A: Both are axial through-hole packages with identical lead spacing and mounting characteristics. DO-15 and DO-204AL (DO-41) are mechanically interchangeable designations for the same physical form factor.

Q: Does the lower forward voltage of the GI250-3-E3/54 affect circuit operation?

A: The substitute exhibits 3.5 V forward voltage at 250 mA versus 4 V at 500 mA for the main part. At the application's 200 mA operating point, the substitute's lower forward voltage reduces power dissipation, improving circuit efficiency without affecting functional performance.

Q: Why is the substitute's capacitance significantly lower (3 pF versus 30 pF)?

A: The lower capacitance of the GI250-3-E3/54 reflects its standard recovery speed technology (>500 ns) compared to the small signal classification of the R3000-AP. Lower capacitance improves high-frequency switching performance and reduces capacitive coupling effects in sensitive circuits.

Q: Are there any temperature range limitations when substituting?

A: No. The substitute's operating range (-65°C to 175°C) fully encompasses the main part's range (-55°C to 150°C), providing equivalent or superior thermal performance across all specified operating conditions.

Q: What is the packaging difference between the main part and substitute?

A: The R3000-AP is supplied in standard packaging, while the GI250-3-E3/54 is supplied in Tape & Reel (TR) format. Both are through-hole components with identical lead configurations suitable for manual or automated assembly.
