ES2JFS Equivalent & Substitute Parts

Part Overview

The ES2JFS is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 2 A average rectified current in a surface mount SOD-128 package. This component is classified as a fast recovery diode with a reverse recovery time of 35 ns, suitable for applications requiring efficient switching characteristics at moderate voltage and current levels. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES2JFS with the HS2JFS is based on strict equivalence of the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 2 A
• Package / Case: SOD-128
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variations: The HS2JFS substitute exhibits differences in reverse recovery time (75 ns versus 35 ns) and junction capacitance (17 pF versus 15 pF at 4 V, 1 MHz). These variations remain within acceptable tolerances for general-purpose rectification applications where the primary functional requirements are voltage blocking capability, current handling, and forward conduction characteristics. Both parts maintain identical reverse leakage current specifications and thermal operating ranges.

Parameter Comparison

Engineering Selection Recommendations

Both the ES2JFS and HS2JFS are active production components manufactured by Taiwan Semiconductor Corporation with identical RoHS3 compliance and unlimited moisture sensitivity classification. Selection between these parts is determined by availability and application-specific requirements regarding switching speed.

The ES2JFS, with a reverse recovery time of 35 ns, is suitable for applications where faster switching transitions and lower switching losses are prioritized. The HS2JFS, with a reverse recovery time of 75 ns, remains within the fast recovery classification and is appropriate for general-purpose rectification where switching speed is not a critical performance constraint.

Both parts are qualified for the full operating temperature range of -55°C to 150°C junction temperature and maintain identical voltage blocking, current handling, and forward conduction characteristics. The 2 pF difference in junction capacitance between the two parts has negligible impact on most rectification circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the HS2JFS directly replace the ES2JFS in any application?

A: The HS2JFS is electrically and mechanically compatible with the ES2JFS for applications where the reverse recovery time specification of 75 ns is acceptable. Both parts share identical voltage ratings (600 V), current ratings (2 A), forward voltage drop (1.7 V @ 2 A), and package configuration (SOD-128 surface mount). Applications sensitive to switching speed performance should evaluate the 40 ns difference in reverse recovery time.

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

A: Reverse recovery time (trr) affects the switching characteristics of the diode during the transition from forward conduction to reverse blocking. The ES2JFS at 35 ns exhibits faster recovery compared to the HS2JFS at 75 ns. Both values remain within the fast recovery classification (≤ 500 ns). Applications with high-frequency switching or stringent switching loss requirements should use the ES2JFS. General-purpose rectification applications tolerate the HS2JFS specification.

Q: Are both parts suitable for high-temperature applications?

A: Both the ES2JFS and HS2JFS are rated for identical operating junction temperature ranges of -55°C to 150°C. Both parts are suitable for high-temperature applications within this specification window.

Q: Do these parts require different PCB layout or thermal management?

A: Both parts use the SOD-128 surface mount package with identical mechanical dimensions and thermal characteristics. PCB layout and thermal management considerations are equivalent between the two parts.

Q: What compliance certifications apply to both parts?

A: Both the ES2JFS and HS2JFS are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. Both parts carry moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Is there a performance difference in reverse leakage current?

A: Both parts specify identical reverse leakage current of 1 µA at 600 V reverse voltage. No performance difference exists in this parameter.
