HS2JAL Equivalent & Substitute Parts

Part Overview

The HS2JAL 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 Thin SMA package. This component is classified as a fast recovery diode with a reverse recovery time of 75 ns, suitable for standard rectification applications requiring moderate switching speeds. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate component availability variations across manufacturing cycles and inventory channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS2JAL rectifier diode is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Equivalence Criteria:

• 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: DO-221AC, SMA Flat Leads
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

Secondary Parameters (Allowable Variation):

• Reverse Recovery Time (trr): Fast recovery classification (≤ 500 ns, > 200 mA)
• Current - Reverse Leakage @ Vr: 1 µA @ 600 V
• Capacitance @ Vr, F: Minor variations acceptable within fast recovery diode specifications

The ES2JAL meets all mandatory equivalence criteria and is classified as a parametric equivalent substitute for the HS2JAL.

Engineering Selection Recommendations

HS2JAL Selection Criteria: The HS2JAL is appropriate for applications requiring a 600 V, 2 A general-purpose rectifier diode with a reverse recovery time of 75 ns. This part is actively manufactured, maintains ROHS3 compliance, and carries unlimited moisture sensitivity classification (MSL 1), eliminating bake-out requirements for standard storage and handling conditions. The HS2JAL is suitable for standard rectification circuits where moderate switching speed is acceptable.

ES2JAL Selection Criteria: The ES2JAL is a parametric equivalent substitute offering identical voltage, current, and forward voltage ratings within the same DO-221AC SMA package. The ES2JAL features a faster reverse recovery time of 35 ns compared to the HS2JAL's 75 ns, resulting in reduced switching losses and improved efficiency in high-frequency rectification applications. Both parts maintain identical RoHS3 compliance and MSL 1 ratings. The ES2JAL is appropriate for applications where faster switching performance is beneficial without requiring design modification.

Compliance and Certification: Both the HS2JAL and ES2JAL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0080. Both parts are suitable for use in regulated applications requiring environmental compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the ES2JAL directly replace the HS2JAL in existing designs?

A: Yes. The ES2JAL is a parametric equivalent substitute with identical voltage (600 V), current (2 A), forward voltage (1.7 V @ 2 A), and package specifications (DO-221AC, SMA Flat Leads). The ES2JAL's faster reverse recovery time (35 ns versus 75 ns) represents an improvement in switching performance and does not create compatibility issues in standard rectification circuits.

Q: What is the primary difference between the HS2JAL and ES2JAL?

A: The primary difference is reverse recovery time. The HS2JAL has a reverse recovery time of 75 ns, while the ES2JAL has 35 ns. This difference affects switching losses in high-frequency applications. The ES2JAL also exhibits slightly lower capacitance (15 pF versus 17 pF at 4 V, 1 MHz), which may provide marginal benefits in high-frequency circuits.

Q: Are both parts available in the same package?

A: Yes. Both the HS2JAL and ES2JAL are supplied in the DO-221AC package with SMA flat leads, configured for surface mount assembly. Both parts are available in Tape & Reel (TR) packaging format.

Q: Do both parts require the same storage and handling procedures?

A: Yes. Both parts are classified as MSL 1 (Unlimited), meaning they do not require moisture bake-out procedures and can be stored under standard warehouse conditions without time-based restrictions.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the HS2JAL and ES2JAL maintain identical compliance status: ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both parts carry the same HTSUS code (8541.10.0080).

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard rectification applications where switching speed is not critical, either part is suitable. For applications requiring lower switching losses or operating at higher frequencies, the ES2JAL's faster reverse recovery time (35 ns) provides performance advantages. Both parts are actively manufactured and available in production quantities.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical surface mount package specifications (DO-221AC, SMA Flat Leads) and are compatible with standard pick-and-place assembly equipment and reflow soldering processes. No PCB layout modifications are required when substituting between these parts.
