Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FES1JE are identified based on strict equivalence of the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parametric Equivalent: FRS1JE (Diodes Incorporated) maintains identical voltage and current ratings, fast recovery speed classification, and identical package designation (DO-219AA). This part is a direct parametric equivalent with variations in reverse recovery time (250 ns vs. 35 ns) and junction capacitance (7 pF vs. 20 pF), both within acceptable tolerance for general-purpose rectification applications.

Similar Manufacturer Part: ES1006FL_R1_00001 (Panjit International Inc.) meets the same voltage, current, and speed classifications but uses a different package form factor (SOD-123FL vs. DO-219AA). This part is classified as similar due to package differences requiring PCB layout modification, though electrical performance parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

FRS1JE Selection: The FRS1JE is a parametric equivalent suitable for direct substitution in applications where the FES1JE is specified. Both parts are manufactured by Diodes Incorporated, share identical voltage and current ratings, and are packaged in the same DO-219AA form factor. Both maintain Active product status and ROHS3 compliance. The FRS1JE exhibits a longer reverse recovery time (250 ns vs. 35 ns) and lower junction capacitance (7 pF vs. 20 pF), which may provide performance advantages in specific switching applications while remaining within the fast recovery speed classification.

ES1006FL_R1_00001 Selection: The ES1006FL_R1_00001 is classified as a similar manufacturer part due to package form factor differences (SOD-123FL vs. DO-219AA). This part maintains equivalent electrical ratings and Active product status with ROHS3 compliance. Selection of this part requires PCB layout modification to accommodate the different package footprint. The ES1006FL_R1_00001 exhibits lower reverse leakage current (500 nA vs. 5 µA) and higher forward voltage (1.7 V vs. 1.3 V), which may impact thermal performance in high-current applications.

Frequently Asked Questions (FAQ)

Q: Can FRS1JE be used as a direct replacement for FES1JE without PCB modification?

A: Yes. The FRS1JE is packaged in the identical DO-219AA form factor and maintains the same footprint as the FES1JE. No PCB layout changes are required for substitution.

Q: What are the differences between FES1JE and FRS1JE?

A: Both parts share identical voltage (600 V), current (1 A), and forward voltage (1.3 V @ 1 A) ratings. The FRS1JE has a longer reverse recovery time (250 ns vs. 35 ns) and lower junction capacitance (7 pF vs. 20 pF). Both are classified as fast recovery diodes and maintain equivalent electrical performance for general-purpose rectification.

Q: Can ES1006FL_R1_00001 replace FES1JE directly on the PCB?

A: No. The ES1006FL_R1_00001 uses a SOD-123FL package, which has a different footprint than the DO-219AA package of the FES1JE. PCB layout modification is required for this substitution.

Q: What is the impact of the higher forward voltage in ES1006FL_R1_00001?

A: The ES1006FL_R1_00001 exhibits a forward voltage of 1.7 V @ 1 A compared to 1.3 V @ 1 A for the FES1JE. This 0.4 V difference results in increased power dissipation and heat generation during forward conduction, which may require thermal management considerations in high-current or high-frequency applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The FES1JE, FRS1JE, and ES1006FL_R1_00001 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and electromagnetic interference (EMI) characteristics. The FES1JE and ES1006FL_R1_00001 both have 35 ns trr, while the FRS1JE has 250 ns trr. All three parts are classified as fast recovery diodes (≤ 500 ns). The difference may be relevant in high-frequency switching applications but does not affect general-purpose rectification performance.

Q: Can these parts be used interchangeably in all applications?

A: FES1JE and FRS1JE can be used interchangeably without PCB modification due to identical packaging. ES1006FL_R1_00001 requires PCB layout changes. All three parts meet the same voltage and current specifications and are suitable for general-purpose rectification applications within the specified operating temperature range (-55°C to 150°C).
