Key Parameters

Substitute Part Grouping Explanation

Substitution of the FSV20150V is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-277 family
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current - Average Rectified (Io): Substitute must equal or exceed 20A requirement
• Voltage - Forward (Vf) (Max) @ If: Substitute values within acceptable circuit design margins
• Current - Reverse Leakage @ Vr: Substitute values within acceptable circuit design margins
• Operating Temperature - Junction: Substitute range must encompass or exceed -55°C ~ 150°C

The V12P15-M3/H meets the mandatory matching parameters but operates at 12A average rectified current, which is below the 20A specification of the FSV20150V. This substitution is valid only in applications where the actual circuit current demand does not exceed 12A.

Parameter Comparison

Engineering Selection Recommendations

The V12P15-M3/H from Vishay General Semiconductor - Diodes Division is listed as an equivalent substitute for the FSV20150V. Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Selection Criteria:

The V12P15-M3/H is suitable for applications where the circuit current demand does not exceed 12A. The substitute component maintains the same 150V reverse voltage rating, fast recovery switching speed, and Surface Mount TO-277 package form factor as the original FSV20150V.

Differences in forward voltage (1.08 V @ 12 A versus 840 mV @ 20 A) and reverse leakage current (250 µA @ 150 V versus 30 µA @ 150 V) must be evaluated within the specific circuit application. The V12P15-M3/H operates with a minimum junction temperature of -40°C, compared to -55°C for the FSV20150V; applications requiring operation below -40°C require alternative selection.

The V12P15-M3/H carries Active product status, indicating ongoing manufacturer support and availability, whereas the FSV20150V is Not For New Designs.

Frequently Asked Questions (FAQ)

Q: Can the V12P15-M3/H directly replace the FSV20150V in all applications?

A: The V12P15-M3/H is mechanically and electrically compatible in applications where the circuit current does not exceed 12A. The FSV20150V is rated for 20A; applications requiring the full 20A capacity require alternative components rated at or above 20A.

Q: What is the significance of the different forward voltage ratings?

A: The V12P15-M3/H exhibits a forward voltage of 1.08 V @ 12 A compared to 840 mV @ 20 A for the FSV20150V. Forward voltage affects power dissipation and thermal performance. Circuit designs must account for this difference in voltage drop calculations.

Q: Are the package designations TO-277-3 and TO-277A (SMPC) compatible?

A: Both components use the TO-277 family package with 3-PowerDFN configuration. The supplier device package designations differ (TO-277-3 versus TO-277A (SMPC)); verify mechanical compatibility with your specific PCB footprint and assembly process.

Q: What does the higher reverse leakage current of the V12P15-M3/H indicate?

A: The V12P15-M3/H exhibits 250 µA @ 150 V reverse leakage compared to 30 µA @ 150 V for the FSV20150V. Higher reverse leakage increases standby current consumption and thermal dissipation. Evaluate impact on circuit performance in low-current or standby operating modes.

Q: Does the V12P15-M3/H support the full temperature range of the FSV20150V?

A: The V12P15-M3/H operates from -40°C to 150°C, while the FSV20150V operates from -55°C to 150°C. Applications requiring operation below -40°C cannot use the V12P15-M3/H as a substitute.

Q: What is the difference between the FSV20150V Not For New Designs status and the V12P15-M3/H Active status?

A: Not For New Designs indicates the FSV20150V has been superseded and is no longer recommended for new circuit designs, though existing inventory remains available. Active status for the V12P15-M3/H indicates ongoing manufacturer support, continued availability, and suitability for new designs.
