HS1JFS Equivalent & Substitute Parts

Part Overview

The HS1JFS is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 1 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 75 ns, 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). Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative sourcing is required.

Substitute Part Grouping Explanation

Substitution of the HS1JFS with equivalent parts is determined by strict electrical and mechanical parameter matching within the rectifier diode category. The primary substitution criteria are:

Mandatory Matching Parameters:

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

Allowable Variation Parameters:

• Reverse Recovery Time (trr): Faster recovery times (lower values) are acceptable as they represent improved performance characteristics without degrading circuit function
• Current - Reverse Leakage @ Vr: Equal or lower values maintain or improve reverse blocking performance
• Capacitance @ Vr, F: Minor variations within the specified measurement conditions do not affect substitution eligibility

The ES1JFS meets all mandatory matching criteria and exhibits improved reverse recovery time (35 ns versus 75 ns), making it a direct parametric equivalent suitable for substitution in applications where the HS1JFS is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the HS1JFS and ES1JFS are Active product status components manufactured by Taiwan Semiconductor Corporation with identical electrical ratings for voltage, current, and forward voltage characteristics. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings, ensuring equivalent regulatory and environmental compliance for industrial and commercial applications.

The ES1JFS exhibits a faster reverse recovery time (35 ns) compared to the HS1JFS (75 ns), which represents improved switching performance without introducing any electrical incompatibility. This characteristic makes the ES1JFS suitable for applications where faster diode recovery is beneficial or required.

Selection between these parts should be based on:

1. Availability and Inventory: Choose the part with adequate stock levels for production schedules
2. Switching Performance Requirements: Select ES1JFS for applications requiring faster recovery characteristics
3. Cost Considerations: Evaluate unit pricing and total cost of ownership for procurement decisions
4. Supply Chain Continuity: Maintain both part numbers in design documentation to support alternative sourcing when primary selection becomes unavailable

Both parts are suitable for direct substitution in SOD-128 surface mount applications operating within the -55°C to 150°C junction temperature range.

Frequently Asked Questions (FAQ)

Q: Can the ES1JFS replace the HS1JFS in existing circuit designs?

A: Yes. The ES1JFS is a direct parametric equivalent with identical voltage, current, and forward voltage ratings. Both parts use the SOD-128 surface mount package and operate within the same temperature range. The faster reverse recovery time of the ES1JFS (35 ns versus 75 ns) represents improved performance and does not introduce incompatibility.

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

A: Reverse recovery time (trr) determines how quickly the diode transitions from conducting to blocking state. The ES1JFS recovers faster (35 ns) than the HS1JFS (75 ns). Faster recovery reduces switching losses and electromagnetic interference in high-frequency applications, making the ES1JFS advantageous for demanding switching circuits.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both the HS1JFS and ES1JFS are surface mount components in SOD-128 packages with identical footprints and mounting requirements. No PCB layout modifications are required when substituting between these parts.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating they do not require special moisture control during storage, handling, or assembly. Standard component storage conditions apply to both parts.

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

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for industrial, commercial, and consumer applications. No additional compliance documentation is required when substituting between these parts.

Q: What inventory levels are available for each part?

A: The HS1JFS has 7,786 pieces in stock, while the ES1JFS has 14,937 pieces in stock. Availability should be verified at the time of procurement to ensure supply continuity.
