Engineering Selection Recommendations

FSV12100V (onsemi) - Primary Part The FSV12100V is classified as "Not For New Designs." This designation indicates the part is in end-of-life status within onsemi's portfolio. Existing designs using this component require alternative sourcing strategies.

V12P10-M3/86A (Vishay General Semiconductor - Diodes Division) - Active Substitute The V12P10-M3/86A is an active product from Vishay, rated for identical voltage and current specifications. Forward voltage is 30 mV higher (700 mV vs. 670 mV), and reverse leakage is 150 µA higher (250 µA vs. 100 µA). Operating temperature range is -40°C to 150°C, which is 15°C narrower at the lower bound. This part is suitable for applications where the lower temperature limit of -40°C is acceptable. RoHS3 compliance and MSL 1 rating are maintained.

SVT12100VB_R2_00001 (Panjit International Inc.) - Parametric Equivalent The SVT12100VB_R2_00001 is an active product from Panjit with identical electrical specifications to the FSV12100V: 670 mV forward voltage, 100 µA reverse leakage, and -55°C to 150°C operating temperature. Package designation is TO-277B. RoHS3 compliance and MSL 1 rating are maintained. This part provides the closest electrical match.

SVT12100V_R1_00001 (Panjit International Inc.) - Parametric Equivalent The SVT12100V_R1_00001 is an active product from Panjit with identical electrical specifications to the FSV12100V: 670 mV forward voltage, 100 µA reverse leakage, and -55°C to 150°C operating temperature. Package designation is TO-277. RoHS3 compliance and MSL 1 rating are maintained. This part provides the closest electrical match.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original FSV12100V.

Frequently Asked Questions (FAQ)

Q: Can the V12P10-M3/86A replace the FSV12100V in all applications? A: The V12P10-M3/86A meets the primary electrical criteria (100 V, 12 A, Schottky, fast recovery). However, it has a narrower operating temperature range (-40°C to 150°C vs. -55°C to 150°C) and higher forward voltage (700 mV vs. 670 mV) and reverse leakage (250 µA vs. 100 µA). Applications requiring operation below -40°C or with strict forward voltage and leakage specifications require evaluation.

Q: What is the difference between the Panjit SVT12100VB_R2_00001 and SVT12100V_R1_00001? A: Both parts are electrically identical with 670 mV forward voltage, 100 µA reverse leakage, and -55°C to 150°C operating temperature. The primary difference is the supplier device package designation: TO-277B versus TO-277. Both are 3-PowerDFN packages. Consult PCB layout and assembly documentation to confirm package compatibility.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed—V12P10-M3/86A, SVT12100VB_R2_00001, and SVT12100V_R1_00001—are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the FSV12100V.

Q: Why is the FSV12100V marked "Not For New Designs"? A: This designation indicates the part is in end-of-life status within onsemi's product portfolio. New designs should use active alternatives. Existing designs may continue using the FSV12100V until inventory is exhausted, after which substitution becomes necessary.

Q: What are the key electrical parameters that determine substitutability? A: The critical parameters are voltage rating (100 V), current rating (12 A), technology (Schottky), forward voltage (≤ 700 mV @ 12 A), reverse leakage (≤ 250 µA @ 100 V), and recovery speed (fast recovery ≤ 500ns). All listed substitutes meet these criteria.

Q: Do the TO-277A, TO-277B, and TO-277 packages have different pinouts? A: All three are variants of the TO-277 family with 3-PowerDFN configuration. Pinout compatibility depends on specific PCB layout and assembly requirements. Consult component datasheets and PCB design files to confirm mechanical and electrical compatibility before substitution.

Q: Can I use the Vishay V12P10-M3/86A in applications requiring -55°C operation? A: No. The V12P10-M3/86A has a minimum operating temperature of -40°C. Applications requiring -55°C operation must use the Panjit SVT12100VB_R2_00001 or SVT12100V_R1_00001, both rated to -55°C.
