BYW29-200 Equivalent & Substitute Parts

Part Overview

The BYW29-200 is an ultrafast rectifier diode rated for 200V DC reverse voltage and 8A average rectified current in a TO-220 package. This part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity. Active substitute parts maintain the same electrical ratings and mechanical compatibility while offering current manufacturing availability and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BYW29-200 are qualified based on the following electrical and mechanical parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 8 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 35 ns maximum
• Mounting Type: Through Hole
• Package / Case: TO-220-2 or compatible TO-220AC
• Operating Temperature Range: -65°C ~ 175°C minimum
• RoHS Compliance: ROHS3 Compliant

Parts meeting these criteria are electrically and mechanically interchangeable for the BYW29-200 application.

Parameter Comparison

Engineering Selection Recommendations

BYW29-200G (onsemi) is the direct manufacturer equivalent with active product status. This part maintains identical electrical specifications and packaging, providing seamless substitution for the obsolete BYW29-200. Both parts are ROHS3 compliant and share the same base product number designation.

VS-MUR820-M3 (Vishay General Semiconductor - Diodes Division) is an alternative substitute meeting all electrical and mechanical requirements. This part is also active and ROHS3 compliant. The forward voltage specification differs slightly (975 mV @ 8 A versus 1.3 V @ 20 A), but both parts satisfy the 200V/8A fast recovery rectifier classification. The TO-220AC package variant is mechanically compatible with TO-220-2 applications.

Both substitute parts provide current manufacturing availability and supply chain continuity for applications previously using the BYW29-200.

Frequently Asked Questions (FAQ)

Q: Can BYW29-200G directly replace BYW29-200 in existing designs?

A: Yes. BYW29-200G is the direct onsemi equivalent with identical electrical ratings (200V, 8A, 35ns reverse recovery time) and TO-220-2 packaging. No circuit modifications are required.

Q: Is VS-MUR820-M3 compatible with BYW29-200 applications?

A: Yes. VS-MUR820-M3 meets all substitution criteria: 200V reverse voltage, 8A average rectified current, 35ns reverse recovery time, and TO-220-2 compatible packaging. The forward voltage specification is measured at different current levels but both parts function as fast recovery rectifiers in the specified application range.

Q: What is the difference between TO-220-2 and TO-220AC packaging?

A: Both are through-hole TO-220 variants with identical pin spacing and mechanical footprint compatibility. TO-220AC is the Vishay designation for the same physical package used in standard TO-220-2 applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. BYW29-200G and VS-MUR820-M3 are both ROHS3 compliant, matching the compliance status of the original BYW29-200.

Q: What determines if a part can substitute for BYW29-200?

A: Substitution requires matching or exceeding the following parameters: 200V DC reverse voltage, 8A average rectified current, fast recovery speed classification (≤500ns), 35ns reverse recovery time, through-hole mounting, TO-220-2 compatible packaging, and -65°C to 175°C operating temperature range.
