BYT30PI-1000RG Equivalent & Substitute Parts

Part Overview

The BYT30PI-1000RG is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 30 A average rectified current in a DOP3I through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The part features fast recovery characteristics with a reverse recovery time of 165 ns and is suitable for applications requiring high-voltage rectification in industrial and power conversion circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BYT30PI-1000RG is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 1000 V
• Current - Average Rectified (Io): Must equal or exceed 30 A
• Mounting Type: Must be Through Hole
• Package / Case: Must be DOP3I-2 Insulated (Straight Leads)

Compliance & Status Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The STTH3010PI meets all substitution criteria. It maintains identical voltage and current ratings, uses the same DOP3I package, and is manufactured by the same supplier (STMicroelectronics). The substitute part is currently in active product status, making it suitable for production applications where the obsolete BYT30PI-1000RG is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The STTH3010PI is a direct substitute for the BYT30PI-1000RG based on electrical and mechanical equivalence. Both parts are manufactured by STMicroelectronics and share identical voltage and current ratings, package configuration, and compliance certifications.

The STTH3010PI offers the following advantages:

• Active Product Status: The substitute is currently in active production, ensuring long-term availability and supply chain continuity.
• Improved Performance Characteristics: The STTH3010PI exhibits lower reverse recovery time (100 ns versus 165 ns) and significantly lower reverse leakage current (15 µA versus 100 µA), resulting in reduced switching losses and improved efficiency.
• Extended Temperature Rating: Maximum junction temperature of 175°C compared to 150°C provides additional thermal margin in high-temperature applications.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

For applications currently using the obsolete BYT30PI-1000RG, direct substitution with STTH3010PI is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the STTH3010PI be used as a direct replacement for the BYT30PI-1000RG?

A: Yes. Both parts share identical voltage ratings (1000 V), current ratings (30 A), and package configuration (DOP3I-2 through-hole). The STTH3010PI is electrically and mechanically compatible for direct substitution.

Q: What are the key differences between these two diodes?

A: The primary differences are product status and performance characteristics. The BYT30PI-1000RG is obsolete, while the STTH3010PI is active. The STTH3010PI features improved reverse recovery time (100 ns versus 165 ns), lower reverse leakage current (15 µA versus 100 µA), and a higher maximum junction temperature (175°C versus 150°C).

Q: Are there any package or pinout differences?

A: No. Both parts use the DOP3I-2 insulated package with straight leads. Physical dimensions and lead configuration are identical, allowing direct board-level substitution without layout modifications.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the BYT30PI-1000RG and STTH3010PI are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: The STTH3010PI should be selected for new designs. As an active product with improved performance characteristics and guaranteed long-term availability, it is the appropriate choice for production applications.

Q: Does the forward voltage difference affect circuit operation?

A: The forward voltage difference is 0.1 V (1.9 V versus 2.0 V at 30 A). This minor variation is within typical design margins for rectifier applications and does not require circuit redesign.
