Engineering Selection Recommendations

Parametric Equivalent Selection (Recommended for Direct Replacement):

The Panjit International Inc. parts SVT15100U_R1_00001 and SVT15100UB_R2_00001 provide full parametric equivalence to the FSV15100V across all critical electrical specifications. Both parts are classified as Active products, ensuring ongoing manufacturer support and supply availability. These components maintain identical forward voltage characteristics (660 mV @ 15 A), reverse leakage current (80 µA @ 100 V), and operating temperature range (-55°C ~ 150°C). The primary distinction between these two Panjit alternatives is the supplier device package designation (TO-277 versus TO-277B), which reflects internal packaging variations that do not affect electrical performance or PCB-level compatibility.

The Vishay V15P10-M3/H represents an alternative parametric equivalent with full 15 A current rating and 100 V voltage specification. This part exhibits slightly elevated forward voltage (710 mV @ 15 A) and reverse leakage current (500 µA @ 100 V) compared to the FSV15100V baseline, but remains within acceptable operating parameters for most applications. The V15P10-M3/H operates across a reduced temperature range (-40°C ~ 150°C minimum), which may be limiting for applications requiring full -55°C lower temperature operation. This part carries automotive qualification (AEC-Q101) and belongs to the eSMP® and TMBS® product series.

Alternative Selection (Reduced Current Applications):

The Vishay SS5P10HM3_A/I provides a 5 A current rating alternative suitable only for applications with reduced current demands. This part is not a direct replacement for 15 A applications but offers superior reverse leakage characteristics (15 µA @ 100 V) and automotive qualification (AEC-Q101). Selection of this part requires circuit-level current analysis to confirm that 5 A operation is sufficient.

Compliance and Supply Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original FSV15100V. Current inventory levels indicate adequate supply for all recommended alternatives, with Vishay SS5P10HM3_A/I showing the highest stock position (22,192 units), followed by Panjit SVT15100UB_R2_00001 (10,878 units) and SVT15100U_R1_00001 (5,097 units).

Frequently Asked Questions (FAQ)

Q: Can the SVT15100U_R1_00001 or SVT15100UB_R2_00001 be used as direct replacements for the FSV15100V?

A: Yes. Both Panjit parts are parametric equivalents meeting all primary electrical specifications: 100 V reverse voltage, 15 A average rectified current, 660 mV forward voltage at 15 A, and 80 µA reverse leakage at 100 V. Operating temperature ranges (-55°C ~ 150°C) and fast recovery speed characteristics are identical. The difference between these two Panjit parts is the supplier device package designation (TO-277 versus TO-277B), which does not affect electrical performance or PCB compatibility.

Q: What is the difference between the Panjit and Vishay 15 A alternatives?

A: The Panjit SVT15100U_R1_00001 and SVT15100UB_R2_00001 provide exact electrical matching to the FSV15100V baseline. The Vishay V15P10-M3/H maintains the 15 A current rating and 100 V voltage specification but exhibits higher forward voltage (710 mV @ 15 A) and reverse leakage current (500 µA @ 100 V). The Vishay part operates across a reduced minimum temperature range (-40°C versus -55°C) and includes automotive qualification (AEC-Q101).

Q: Is the Vishay SS5P10HM3_A/I a suitable replacement?

A: The SS5P10HM3_A/I is not a direct replacement due to its 5 A current rating versus the 15 A requirement of the FSV15100V. This part is suitable only for applications with confirmed current demands of 5 A or less. The SS5P10HM3_A/I offers superior reverse leakage characteristics (15 µA @ 100 V) and automotive qualification (AEC-Q101).

Q: Are all substitute parts available in the same package?

A: All substitute parts use the TO-277, 3-PowerDFN package family with Surface Mount mounting. Supplier device package designations vary (TO-277, TO-277A, TO-277B, TO-277-3), reflecting internal packaging variations that do not affect PCB-level compatibility or electrical performance.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts are ROHS3 compliant and REACH unaffected. The Vishay parts (V15P10-M3/H and SS5P10HM3_A/I) carry additional automotive qualification per AEC-Q101. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: What is the product status of the substitute parts?

A: All substitute parts are classified as Active products, ensuring ongoing manufacturer support, design documentation, and supply chain availability. The original FSV15100V is classified as Not For New Designs, making transition to an active alternative necessary for new designs and long-term supply security.

Q: Are there temperature range limitations with any substitute?

A: The Vishay V15P10-M3/H operates across a minimum temperature range of -40°C to 150°C, compared to -55°C to 150°C for the FSV15100V and Panjit alternatives. Applications requiring operation below -40°C must use the Panjit SVT15100U_R1_00001, SVT15100UB_R2_00001, or Vishay SS5P10HM3_A/I.

Q: How do forward voltage characteristics compare across substitutes?

A: The FSV15100V, SVT15100U_R1_00001, and SVT15100UB_R2_00001 all specify 660 mV maximum forward voltage at 15 A. The Vishay V15P10-M3/H specifies 710 mV at 15 A, representing a 50 mV increase. The Vishay SS5P10HM3_A/I specifies 880 mV at 5 A, which is not directly comparable due to the different current rating.

Q: What reverse leakage current differences exist?

A: The FSV15100V, SVT15100U_R1_00001, and SVT15100UB_R2_00001 specify 80 µA reverse leakage at 100 V. The Vishay V15P10-M3/H specifies 500 µA at 100 V, representing a 6.25x increase. The Vishay SS5P10HM3_A/I specifies 15 µA at 100 V, representing superior leakage performance.
