ES2JAL General Purpose Rectifier Diode 600V 2A Thin SMA

Part Overview

The ES2JAL is a general purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the DO-221AC (SMA Flat Leads) package. This component operates at 600V DC reverse voltage with a 2A average rectified current rating and features fast recovery characteristics with a 35 ns reverse recovery time. The part is classified as Active product status and carries full RoHS3 compliance with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives that maintain electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ES2JAL is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Voltage - DC Reverse (Vr) Maximum: 600V
• Current - Average Rectified (Io): 2A
• Voltage - Forward (Vf) Maximum @ If: 1.7V @ 2A
• Package / Case: DO-221AC, SMA Flat Leads
• Operating Temperature Range: -55°C to 150°C
• RoHS3 Compliance Status
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variance: Reverse recovery time (trr) and junction capacitance may vary within the fast recovery classification (≤500ns for currents >200mA) without affecting functional substitution, provided all mandatory parameters remain identical.

The HS2JAL qualifies as a parametric equivalent substitute based on full alignment with all mandatory equivalence parameters. Variance in reverse recovery time (75 ns versus 35 ns) and capacitance (17pF versus 15pF) remains within acceptable tolerance for general purpose rectification applications while maintaining the fast recovery speed classification.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (ES2JAL): The ES2JAL is the preferred selection when available. This part maintains Active product status with confirmed inventory of 821 pieces in stock. Full RoHS3 compliance and REACH unaffected status satisfy regulatory requirements for commercial and industrial applications. The 35 ns reverse recovery time provides optimal performance characteristics for fast switching applications.

Substitute Part Selection (HS2JAL): The HS2JAL serves as a direct functional substitute when ES2JAL availability is constrained. This part carries identical electrical ratings, package specifications, and regulatory compliance certifications. Higher inventory availability (4553 pieces) supports extended production runs. The 75 ns reverse recovery time remains within fast recovery classification and maintains compatibility with general purpose rectification circuit designs. Selection of HS2JAL does not require circuit redesign or performance re-qualification when substituting for ES2JAL in existing designs.

Both parts satisfy identical compliance requirements (RoHS3, REACH unaffected, EAR99 ECCN classification) and operate across the full -55°C to 150°C junction temperature range.

Frequently Asked Questions (FAQ)

Q: Can HS2JAL be used as a direct replacement for ES2JAL in production designs?

A: Yes. The HS2JAL meets all mandatory electrical and mechanical parameters required for ES2JAL substitution. Both parts share identical voltage ratings (600V), current ratings (2A), forward voltage characteristics (1.7V @ 2A), package configuration (DO-221AC SMA Flat Leads), and operating temperature range (-55°C to 150°C). No circuit modifications are required.

Q: What is the significance of the reverse recovery time difference between ES2JAL (35 ns) and HS2JAL (75 ns)?

A: Both parts maintain fast recovery classification (≤500ns for currents >200mA). The 40 ns variance does not affect functional compatibility in general purpose rectification applications. Selection between these parts depends on specific circuit switching frequency requirements and EMI performance specifications, which are not altered by this parameter variance within the fast recovery range.

Q: Are there any package or mounting differences between ES2JAL and HS2JAL?

A: No. Both parts use identical DO-221AC package configuration with SMA Flat Leads for surface mount assembly. PCB footprints, reflow profiles, and handling procedures are identical. No changes to manufacturing processes or assembly equipment are required when substituting between these parts.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both ES2JAL and HS2JAL carry RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts. No additional compliance documentation or qualification is required when substituting between these parts.

Q: What is the capacitance difference between ES2JAL (15 pF) and HS2JAL (17 pF), and does it affect circuit performance?

A: The 2 pF variance in junction capacitance at 4V and 1MHz represents a 13% increase. This difference is negligible for general purpose rectification applications. Capacitance becomes a selection criterion only in high-frequency switching circuits or precision timing applications where junction capacitance directly affects circuit performance. For standard rectification functions, this variance does not require circuit re-analysis.

Q: Which part should be selected for new design implementations?

A: Either part is acceptable for new designs. Selection should be based on availability, lead time, and inventory requirements. Both parts provide identical electrical performance and regulatory compliance. Design documentation should specify both ES2JAL and HS2JAL as acceptable alternatives to maximize supply chain flexibility.
