FSV530AF Equivalent & Substitute Parts

Part Overview

The FSV530AF is a Schottky rectifier diode manufactured by onsemi, rated for 30 V DC reverse voltage and 5 A average rectified current in a DO-214AD (SMAF) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The FSV530AF serves applications requiring fast recovery Schottky diode performance with low forward voltage drop characteristics typical of this device category.

Substitute Part Grouping Explanation

Substitution of the FSV530AF is determined by alignment of critical electrical parameters: reverse voltage rating (Vr), average rectified current (Io), forward voltage characteristics (Vf), and reverse recovery time (trr). All substitute parts must maintain Schottky technology classification and surface mount mounting type. Package compatibility is evaluated separately, as different surface mount packages (DO-214AD, DO-221AC, SOD-128) may require circuit board layout modifications.

The substitute parts are grouped into two categories:

Direct Electrical Equivalents: Parts matching the 30 V / 5 A rating with identical or superior electrical performance characteristics.

Functional Alternatives: Parts with higher voltage ratings or slightly reduced current ratings that operate within the FSV530AF application envelope while offering active product status and improved availability.

Engineering Selection Recommendations

SB53AFC_R1_00001 (Panjit International Inc.) provides the closest electrical match to the FSV530AF. This part maintains identical 30 V / 5 A ratings, matching forward voltage (540 mV @ 5 A), and reverse leakage characteristics (100 µA @ 30 V). The SB53AFC_R1_00001 is active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Package transition from DO-214AD to DO-221AC (SMAF-C) requires circuit board layout evaluation.

PMEG3050BEP,115 (Nexperia USA Inc.) offers superior forward voltage performance (450 mV @ 5 A) compared to the FSV530AF while maintaining identical voltage and current ratings. This part is active product status with ROHS3 compliance. The SOD-128 package represents a different form factor requiring board layout modification. Reverse leakage is elevated at 250 µA @ 30 V.

MBRAF440T3G (onsemi) provides higher voltage rating (40 V) with reduced current capacity (4 A). This part is suitable for applications where the FSV530AF operates below 4 A average rectified current and where higher reverse voltage margin is acceptable. The MBRAF440T3G is active product status with ROHS3 compliance and represents the same manufacturer as the original part.

All substitute parts maintain fast recovery Schottky technology, surface mount mounting type, and compliance certifications equivalent to the FSV530AF.

Frequently Asked Questions (FAQ)

Q: Can the SB53AFC_R1_00001 directly replace the FSV530AF without circuit modification?

A: Electrical substitution is valid. The SB53AFC_R1_00001 matches the 30 V / 5 A ratings and forward voltage characteristics. However, the package changes from DO-214AD to DO-221AC (SMAF-C), requiring verification of circuit board pad layout and footprint compatibility.

Q: What is the primary advantage of the PMEG3050BEP,115 over the FSV530AF?

A: The PMEG3050BEP,115 delivers lower forward voltage drop (450 mV @ 5 A versus 540 mV @ 5 A), reducing power dissipation in the diode. This characteristic is beneficial in high-current or thermally constrained applications. The SOD-128 package requires board layout evaluation.

Q: Is the MBRAF440T3G suitable for all FSV530AF applications?

A: The MBRAF440T3G is suitable only for applications where average rectified current does not exceed 4 A. The higher 40 V reverse voltage rating provides additional margin but does not enhance performance in circuits designed for 30 V operation. Package compatibility (SMA-FL versus DO-214AD) requires board layout assessment.

Q: Do all substitute parts maintain the same operating temperature range as the FSV530AF?

A: The SB53AFC_R1_00001 and MBRAF440T3G maintain the -55°C ~ 150°C junction temperature range. The PMEG3050BEP,115 specifies 150°C maximum junction temperature without a minimum specification, requiring thermal design review for low-temperature applications below -55°C.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed (SB53AFC_R1_00001, PMEG3050BEP,115, MBRAF440T3G) are ROHS3 compliant with moisture sensitivity level 1 (unlimited), matching the FSV530AF compliance profile.

Q: What package considerations apply when substituting the FSV530AF?

A: The FSV530AF uses DO-214AD (SMAF) package. The SB53AFC_R1_00001 uses DO-221AC (SMAF-C), and the PMEG3050BEP,115 uses SOD-128. Each package transition requires circuit board footprint verification and potential layout modification. The MBRAF440T3G uses SMA-FL package.
