TS4K80-A Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The TS4K80-A is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 800 V peak reverse voltage and 4 A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in the 800 V class. The TS4K80-A is discontinued at DiGi Electronics, necessitating identification of equivalent parts for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS4K80-A bridge rectifier is determined by strict electrical and mechanical parameter matching within the single-phase bridge rectifier category. The critical parameters that define substitution eligibility are:

Electrical Parameters:

• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 4 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 2 A
• Current - Reverse Leakage @ Vr: 10 µA @ 800 V

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: 4-SIP, TS4K

Environmental & Compliance Parameters:

• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

A substitute part must match all specified electrical ratings, maintain through-hole mounting compatibility, conform to the 4-SIP TS4K package footprint, and satisfy all environmental and regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The TS4K80-A is the direct equivalent part for applications requiring an 800 V, 4 A single-phase bridge rectifier in through-hole 4-SIP TS4K package configuration. This component maintains full compliance with ROHS3 and REACH regulatory requirements, with unlimited moisture sensitivity classification suitable for standard storage and handling conditions.

Selection of this part is appropriate for applications with the following requirements:

• Peak reverse voltage rating of 800 V
• Average rectified current of 4 A
• Through-hole mounting on printed circuit boards
• Operating temperature range from -55°C to 150°C
• Regulatory compliance with ROHS3 and REACH standards

The part's discontinued status at DiGi Electronics does not affect its technical suitability for new designs; alternative procurement channels may be required for sourcing.

Frequently Asked Questions (FAQ)

Q: What defines electrical compatibility for the TS4K80-A bridge rectifier?

A: Electrical compatibility requires matching of peak reverse voltage (800 V), average rectified current (4 A), forward voltage drop (1 V @ 2 A), and reverse leakage current (10 µA @ 800 V). All four parameters must be identical for direct substitution.

Q: Is the 4-SIP TS4K package footprint critical for substitution?

A: Yes. The through-hole 4-SIP TS4K package defines the physical mounting interface. Substitutes must use identical package geometry to ensure PCB compatibility without layout modifications.

Q: Can the TS4K80-A be used in applications requiring lower voltage ratings?

A: The TS4K80-A is rated for 800 V peak reverse voltage. Use in lower voltage applications is not a substitution consideration; the component is suitable for any application within or below its rated specifications.

Q: What is the significance of the ROHS3 compliance status?

A: ROHS3 compliance indicates the component meets European Union Restriction of Hazardous Substances Directive requirements. This certification is maintained across equivalent parts and is relevant for applications subject to regulatory compliance mandates.

Q: Does the MSL 1 (Unlimited) rating affect storage or handling procedures?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity limitations. Standard storage conditions without specialized moisture control are acceptable.

Q: Are there any thermal considerations for the TS4K80-A operating temperature range?

A: The component is rated for junction temperatures from -55°C to 150°C (TJ). Applications must ensure the component operates within this range under worst-case thermal conditions.
