HS1JLW Equivalent & Substitute Parts

Part Overview

The HS1JLW is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600V DC reverse voltage and 1A average rectified current in a surface mount SOD-123W package. This component is classified as a fast recovery diode with a reverse recovery time of 75 nanoseconds, suitable for standard rectification applications requiring moderate switching speeds. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HS1JLW rectifier diode is determined by strict equivalence across the following critical parameters:

Voltage Rating: Both the main part and substitute must maintain 600V DC reverse voltage maximum to ensure safe operation in the target circuit.

Current Rating: The 1A average rectified current specification must be matched or exceeded to prevent thermal stress and component failure.

Forward Voltage Drop: The maximum forward voltage of 1.7V at 1A forward current establishes the conduction loss profile and must be maintained for circuit performance consistency.

Package and Mounting: The SOD-123W surface mount package defines mechanical compatibility with printed circuit board layouts and automated assembly processes.

Operating Temperature Range: The -55°C to 175°C junction temperature range must be supported to ensure reliability across specified environmental conditions.

Compliance Standards: RoHS3 compliance and REACH unaffected status are mandatory for regulatory and supply chain requirements.

The ES1JLW meets all these criteria while introducing variations in reverse recovery time (35 ns versus 75 ns) and reverse leakage current (5 µA versus 1 µA), which represent performance improvements rather than incompatibilities.

Engineering Selection Recommendations

Primary Selection (HS1JLW): Select the HS1JLW when the application requires the specified reverse recovery time of 75 nanoseconds and reverse leakage current of 1 µA at 600V. This part is Active in product status with full RoHS3 compliance and REACH unaffected designation, supporting long-term supply chain stability.

Substitute Selection (ES1JLW): The ES1JLW is a direct substitute when improved switching performance is acceptable or beneficial. This part delivers faster reverse recovery (35 ns) and maintains identical voltage, current, and forward voltage specifications. Both parts share identical RoHS3 compliance, REACH status, and operating temperature range. The ES1JLW exhibits higher reverse leakage current (5 µA) and slightly increased capacitance (20 pF), which may be advantageous in high-frequency switching applications but require circuit validation in leakage-sensitive designs.

Both parts are manufactured by Taiwan Semiconductor Corporation and maintain Active product status, ensuring availability and supply continuity. Selection between these parts depends on application-specific requirements for switching speed and leakage characteristics within the identical voltage and current envelope.

Frequently Asked Questions (FAQ)

Q: Can the ES1JLW replace the HS1JLW in any application?

A: The ES1JLW is electrically compatible as a substitute for the HS1JLW across voltage (600V), current (1A), and forward voltage (1.7V @ 1A) specifications. The faster reverse recovery time (35 ns versus 75 ns) and higher reverse leakage current (5 µA versus 1 µA) represent performance variations that must be evaluated against specific circuit requirements. Applications sensitive to leakage current or requiring the original switching speed specification should retain the HS1JLW.

Q: Are both parts identical in physical dimensions and PCB footprint?

A: Both the HS1JLW and ES1JLW use the SOD-123W surface mount package with identical mechanical specifications. PCB footprints and automated assembly processes are directly compatible between these parts.

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

A: The ES1JLW exhibits a reverse recovery time of 35 nanoseconds compared to the HS1JLW at 75 nanoseconds. Faster reverse recovery reduces switching losses and electromagnetic interference in high-frequency rectification circuits. This improvement is beneficial in most applications but does not affect DC rectification performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HS1JLW and ES1JLW are RoHS3 compliant, REACH unaffected, and carry identical regulatory designations (ECCN: EAR99, HTSUS: 8541.10.0080). Moisture sensitivity level is 1 (Unlimited) for both parts, indicating no special handling requirements.

Q: What is the impact of the reverse leakage current difference?

A: The ES1JLW exhibits 5 µA reverse leakage at 600V compared to 1 µA for the HS1JLW. In most general-purpose rectification applications, this difference is negligible. However, in precision analog circuits, high-impedance sensing circuits, or applications with extended reverse voltage exposure, the lower leakage of the HS1JLW may be preferred.

Q: Are there inventory or lead time considerations between these parts?

A: The ES1JLW maintains significantly higher inventory (62,371 pieces) compared to the HS1JLW (669 pieces). This inventory difference may influence procurement decisions when supply continuity is a priority.
