5KP220CA-B Equivalent & Substitute Parts

Part Overview

The 5KP220CA-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose overvoltage protection applications. This through-hole component features a 220V reverse standoff voltage rating and 5000W peak pulse power handling capability. The part is currently in active production status with 831 units available in inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5KP220CA-B is determined by the following critical parameters:

• Voltage - Reverse Standoff rating within the 220V class
• Voltage - Breakdown minimum threshold compatibility
• Voltage - Clamping performance at specified peak pulse current
• Peak pulse power rating of 5000W or greater
• Through-hole axial mounting configuration
• Bidirectional suppression capability (1 channel)
• Operating temperature range of -55°C to 175°C (TJ)
• Zener diode type classification
• RoHS3 compliance and REACH unaffected status

The 1.5KE250CA from Taiwan Semiconductor Corporation meets substitution criteria based on equivalent electrical classification, matching operating temperature range, compatible through-hole axial package format, and equivalent compliance certifications. However, the 1.5KE250CA operates at a higher voltage class (250V standoff) with reduced peak pulse current (4.5A) and lower peak pulse power (1500W), requiring application-level verification of voltage and current requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 5KP220CA-B and 1.5KE250CA are active production components with RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The 5KP220CA-B provides higher peak pulse current handling (13.7A versus 4.5A) and significantly greater peak pulse power dissipation (5000W versus 1500W). The 1.5KE250CA operates at a marginally higher reverse standoff voltage (214V typical versus 220V) with lower clamping voltage (344V versus 371.1V).

Selection between these parts depends on application-specific requirements for peak pulse current and power dissipation. The 1.5KE250CA includes AEC-Q101 automotive qualification, which may be relevant for automotive or harsh-environment applications. Package compatibility must be verified, as the 5KP220CA-B uses P600 package while the 1.5KE250CA uses DO-201AA or DO-27 package formats.

Frequently Asked Questions (FAQ)

Q: What determines if a TVS diode can substitute for the 5KP220CA-B?

A: Substitution eligibility is based on matching voltage class (220V reverse standoff range), equivalent or superior peak pulse current and power ratings, compatible through-hole axial mounting, matching operating temperature range (-55°C to 175°C), and equivalent compliance certifications (RoHS3, REACH).

Q: How does the 1.5KE250CA differ from the 5KP220CA-B?

A: The 1.5KE250CA operates at a higher voltage class (250V standoff) with reduced peak pulse current (4.5A versus 13.7A) and lower peak pulse power (1500W versus 5000W). Both use through-hole axial mounting and share identical operating temperature ranges and compliance status.

Q: Are the packages physically compatible?

A: The 5KP220CA-B uses P600 axial package while the 1.5KE250CA uses DO-201AA or DO-27 axial package. Both are through-hole axial formats, but physical dimensions and PCB footprints differ and must be verified for mechanical fit.

Q: Can the 1.5KE250CA handle the same peak pulse power as the 5KP220CA-B?

A: No. The 1.5KE250CA is rated for 1500W peak pulse power compared to the 5KP220CA-B's 5000W rating. Applications requiring the full 5000W dissipation capability cannot use the 1.5KE250CA as a direct substitute.

Q: What is the voltage difference between these parts?

A: The 5KP220CA-B has a 220V typical reverse standoff voltage with 244V minimum breakdown. The 1.5KE250CA has a 214V typical reverse standoff voltage with 237V minimum breakdown. The 1.5KE250CA operates at a lower voltage class despite its higher part number designation.
