FSV15150V Equivalent & Substitute Parts

Part Overview

The FSV15150V is a Schottky rectifier diode manufactured by onsemi, rated for 150 V DC reverse voltage and 15 A average rectified current in a Surface Mount TO-277-3 package. This component is classified as Not For New Designs, indicating it has been superseded in onsemi's product portfolio. Equivalent and substitute parts are necessary for applications requiring continued sourcing, design flexibility, or alternative supplier options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the FSV15150V is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 15 A
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-277, 3-PowerDFN
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Within device-specific ratings
• Current - Reverse Leakage @ Vr: Within device-specific ratings
• Operating Temperature - Junction: Device-specific ranges
• Supplier Device Package: TO-277 variants (TO-277-3, TO-277A, TO-277B)

The substitute parts V15P15-M3/H and CDBHA15150-HF meet all mandatory matching parameters and are therefore classified as electrical and mechanical equivalents suitable for direct replacement in applications designed for the FSV15150V.

Parameter Comparison

Engineering Selection Recommendations

FSV15150V (onsemi): This part carries a Not For New Designs status, indicating it is obsolete or superseded. It remains suitable for legacy system maintenance and repair applications where original component specifications are required. ROHS3 compliance and MSL 1 rating support continued use in existing designs.

V15P15-M3/H (Vishay General Semiconductor - Diodes Division): This part is Active and recommended for new designs requiring 150 V / 15 A Schottky rectification. The eSMP® and TMBS® series designation indicates optimized performance characteristics. Forward voltage is higher at 1.08 V compared to 850 mV, resulting in increased power dissipation. Operating temperature range is -40°C to 150°C, which is narrower at the lower bound than the FSV15150V. ROHS3 compliance and MSL 1 rating are maintained. Packaging is Tape & Reel (TR) format.

CDBHA15150-HF (Comchip Technology): This part is Active and provides parametric equivalence to the FSV15150V with matching forward voltage of 850 mV @ 15 A and operating temperature range of -55°C to 150°C. Reverse leakage current is 250 µA, intermediate between the FSV15150V (30 µA) and V15P15-M3/H (300 µA). ROHS3 compliance and MSL 1 rating are maintained. Packaging is Tape & Reel (TR) format.

Frequently Asked Questions (FAQ)

Q: Can V15P15-M3/H be used as a direct replacement for FSV15150V?

A: V15P15-M3/H is electrically and mechanically equivalent in terms of voltage rating, current rating, and package type. However, the forward voltage specification differs (1.08 V versus 850 mV at 15 A), which affects power dissipation and thermal performance. The lower operating temperature minimum (-40°C versus -55°C) may be a constraint in extreme cold environments. Circuit thermal analysis is required to confirm suitability.

Q: What is the difference between TO-277-3, TO-277A, and TO-277B packages?

A: All three are variants of the TO-277 3-PowerDFN package family used for surface mount Schottky diodes. The designations (TO-277-3, TO-277A, TO-277B) represent supplier-specific package configurations. Physical dimensions and lead configurations are compatible within the TO-277 family, supporting direct PCB layout compatibility.

Q: Why does CDBHA15150-HF have higher reverse leakage current than FSV15150V?

A: Reverse leakage current (30 µA for FSV15150V versus 250 µA for CDBHA15150-HF) is a device-specific characteristic determined by semiconductor manufacturing and design. Both values are within acceptable limits for 150 V Schottky rectifiers. Higher leakage results in marginally increased standby power consumption but does not affect forward rectification performance.

Q: Are all three parts RoHS3 compliant?

A: Yes. FSV15150V, V15P15-M3/H, and CDBHA15150-HF are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, supporting use in standard manufacturing and storage environments without special handling.

Q: Which substitute part is recommended for new designs?

A: V15P15-M3/H and CDBHA15150-HF are both Active products suitable for new designs. V15P15-M3/H is from Vishay, a major supplier with established distribution. CDBHA15150-HF is from Comchip Technology and offers closer parametric match to the original FSV15150V, particularly in forward voltage and operating temperature range. Selection depends on supply chain availability, cost, and thermal design requirements.

Q: What is the impact of different forward voltage specifications on circuit performance?

A: Forward voltage directly affects power dissipation in the diode. At 15 A, FSV15150V and CDBHA15150-HF dissipate 12.75 W (850 mV × 15 A), while V15P15-M3/H dissipates 16.2 W (1.08 V × 15 A). The 3.45 W difference requires thermal management evaluation in high-current applications. Heat sink sizing and PCB thermal design must account for this variation.
