Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BYT30PI-1000 are identified based on electrical and mechanical compatibility within the rectifier diode category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 30 A
• Mounting Type: Through Hole
• Package / Case: DOP3I-2 Insulated (Straight Leads)
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io)

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
• Reverse Recovery Time (trr): Improved performance acceptable
• Current - Reverse Leakage @ Vr: Lower values acceptable
• Operating Temperature - Junction: Extended range acceptable
• Product Status: Active status preferred for availability
• RoHS Compliance: Improved compliance status acceptable

The STTH3010PI meets all critical matching parameters and demonstrates improved electrical characteristics in secondary parameters, making it a direct substitute for the obsolete BYT30PI-1000.

Parameter Comparison

Engineering Selection Recommendations

The STTH3010PI is the direct substitute for the obsolete BYT30PI-1000. Selection of this substitute is based on the following engineering factors:

Product Status: The BYT30PI-1000 is obsolete and no longer manufactured. The STTH3010PI is active and currently in production, ensuring long-term availability for component procurement.

Electrical Compatibility: Both parts share identical voltage and current ratings (1000 V, 30 A) and identical fast recovery speed classification. The STTH3010PI demonstrates improved reverse recovery time (100 ns versus 165 ns) and significantly lower reverse leakage current (15 µA versus 100 µA), resulting in enhanced performance characteristics.

Mechanical Compatibility: Both parts use identical through-hole mounting and DOP3I-2 package configuration, ensuring direct physical and electrical compatibility in existing circuit board layouts.

Regulatory Compliance: The STTH3010PI is ROHS3 compliant, whereas the BYT30PI-1000 is non-compliant. This upgrade supports compliance with current environmental and regulatory standards.

Thermal Performance: The STTH3010PI supports an extended maximum junction temperature of 175°C compared to 150°C for the BYT30PI-1000, providing additional thermal margin in high-temperature applications.

Frequently Asked Questions (FAQ)

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

A: Yes. The STTH3010PI is a direct substitute. Both parts share identical voltage ratings (1000 V), current ratings (30 A), mounting type (through hole), and package configuration (DOP3I-2). No circuit modifications are required.

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

A: The primary differences are product status and performance characteristics. The BYT30PI-1000 is obsolete; the STTH3010PI is active. The STTH3010PI offers improved reverse recovery time (100 ns versus 165 ns), lower reverse leakage current (15 µA versus 100 µA), extended maximum junction temperature (175°C versus 150°C), and ROHS3 compliance versus non-compliance.

Q: Are there any compatibility concerns with the forward voltage difference?

A: No. The forward voltage difference (1.9 V versus 2 V at 30 A) is within acceptable operating range for rectifier diode applications. This 0.1 V difference does not affect circuit functionality or component compatibility.

Q: Is the improved reverse recovery time of the STTH3010PI beneficial?

A: Yes. Faster reverse recovery time (100 ns versus 165 ns) reduces switching losses and improves efficiency in high-frequency rectification applications. This represents an enhancement over the original part.

Q: Does the STTH3010PI meet current regulatory requirements?

A: Yes. The STTH3010PI is ROHS3 compliant, meeting current environmental and regulatory standards. The BYT30PI-1000 is non-compliant with RoHS requirements.

Q: Are both parts available from the same manufacturer?

A: Yes. Both the BYT30PI-1000 and STTH3010PI are manufactured by STMicroelectronics, ensuring consistent quality and reliability standards.

Q: What is the impact of lower reverse leakage current in the STTH3010PI?

A: Lower reverse leakage current (15 µA versus 100 µA) reduces standby power consumption and heat generation, improving overall circuit efficiency and reliability in applications with extended idle periods.
