Key Parameters

Substitute Part Grouping Explanation

Substitution of the BYW99P-200 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (must match)
• Voltage - DC Reverse (Vr) (Max): 200 V (must match or exceed)
• Current - Average Rectified (Io) (per Diode): 15 A (must match or exceed)
• Technology: Standard (must match)
• Speed Classification: Fast Recovery ≤ 500 ns, > 200 mA (Io) (must match)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (must match)
• Diode array configuration and pin count (must be compatible with circuit board layout)

The STTH2002CT meets all electrical criteria for substitution. Both components share identical voltage ratings, current ratings, diode configuration, technology classification, and speed characteristics. The primary difference is the package format: the BYW99P-200 uses TO-218-3 packaging, while the STTH2002CT uses TO-220-3 packaging. Both are through-hole packages with compatible pin configurations for the 1 Pair Common Cathode topology.

Parameter Comparison

Engineering Selection Recommendations

The STTH2002CT is a direct functional substitute for the BYW99P-200 based on electrical parameter equivalence. Both components are manufactured by STMicroelectronics and maintain ROHS3 compliance.

Key Selection Factors:

1. Product Status: The BYW99P-200 is obsolete, while the STTH2002CT is active. The STTH2002CT offers ongoing availability and manufacturer support.

2. Electrical Equivalence: All critical electrical parameters are identical: 200 V reverse voltage rating, 15 A average rectified current per diode, 1 Pair Common Cathode configuration, and fast recovery technology classification.

3. Performance Characteristics: The STTH2002CT demonstrates improved performance metrics, including faster reverse recovery time (27 ns versus 40 ns) and lower reverse leakage current (10 µA versus 20 µA at 200 V).

4. Thermal Capability: The STTH2002CT supports a maximum junction temperature of 175°C, compared to the BYW99P-200 upper limit of 150°C.

5. Package Consideration: The primary physical difference is the package format. The BYW99P-200 uses TO-218-3 packaging, while the STTH2002CT uses TO-220-3 packaging. Both are through-hole packages with compatible pin configurations for common cathode diode pair applications. PCB layout modification may be required to accommodate the different package footprint.

6. Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the STTH2002CT directly replace the BYW99P-200 without circuit modification?

A: The STTH2002CT is electrically equivalent to the BYW99P-200 in all critical parameters. However, the package format differs (TO-220-3 versus TO-218-3). Direct PCB mounting without layout modification is not possible. The circuit board footprint must be adapted to accommodate the TO-220-3 package, or an adapter solution must be implemented.

Q: Are the pin configurations compatible between these two packages?

A: Both the TO-218-3 and TO-220-3 packages support the 1 Pair Common Cathode diode configuration with three pins. The functional pin assignments are compatible, but the physical pin spacing and mounting hole locations differ between the two package types.

Q: What are the electrical advantages of the STTH2002CT over the BYW99P-200?

A: The STTH2002CT offers improved reverse recovery time (27 ns versus 40 ns) and lower reverse leakage current (10 µA versus 20 µA at 200 V). These characteristics result in reduced switching losses and improved efficiency in rectification applications. The STTH2002CT also supports a higher maximum junction temperature (175°C versus 150°C).

Q: Is the STTH2002CT suitable for all applications where the BYW99P-200 was used?

A: The STTH2002CT is electrically suitable for all applications requiring a 200 V, 15 A, 1 Pair Common Cathode fast recovery diode array. The improved performance characteristics of the STTH2002CT make it suitable for the same or more demanding applications. PCB layout compatibility must be verified for the specific application.

Q: What is the availability status of these components?

A: The BYW99P-200 is obsolete and has limited availability. The STTH2002CT is an active product with current manufacturing and distribution support from STMicroelectronics.

Q: Are there any thermal management differences between the two packages?

A: The TO-218-3 and TO-220-3 packages have different thermal characteristics due to their distinct physical designs. The TO-220-3 package is widely used in industrial applications and offers established thermal management practices. Thermal performance in a specific application depends on PCB layout, heatsinking, and airflow conditions.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the BYW99P-200 and STTH2002CT are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and the same HTSUS code (8541.10.0080).
