5KP120CA-TP Equivalent & Substitute Parts

Part Overview

The 5KP120CA-TP is a transient voltage suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This bidirectional zener diode operates with a 120V reverse standoff voltage and provides 5kW peak pulse power dissipation in an R-6 axial through-hole package. The device is ROHS3 compliant and maintains an active product status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or application-specific power handling requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP120CA-TP are qualified based on the following electrical and mechanical criteria:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 120V
• Bidirectional Channels: 1
• Type: Zener
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: ±2% tolerance acceptable (193V ± 3.86V range)
• Power - Peak Pulse: Equal or greater capacity
• Package / Case: Axial through-hole configurations (R-6 or P600)
• Packaging Format: Tape & Reel or Bulk

The 15KPA120CA and 30KPA120CA meet all critical matching parameters. Both devices maintain the 120V reverse standoff voltage, zener type classification, and through-hole mounting configuration. Clamping voltages (192.3V and 194.4V respectively) fall within acceptable tolerance. Peak pulse power ratings (15kW and 30kW) exceed the original 5kW specification, providing enhanced transient protection capability.

Parameter Comparison

Engineering Selection Recommendations

All three devices maintain active product status and ROHS3 compliance, qualifying them for equivalent substitution in 120V TVS applications. Selection between the 5KP120CA-TP and its substitutes depends on application-specific transient energy requirements:

5KP120CA-TP (5kW): Suitable for standard overvoltage protection in general-purpose circuits with moderate transient energy exposure.

15KPA120CA (15kW): Provides threefold power dissipation capacity, appropriate for applications experiencing higher transient pulse energy or requiring enhanced margin above nominal protection levels.

30KPA120CA (30kW): Delivers sixfold power dissipation capacity relative to the original part, specified for high-energy transient environments or applications requiring maximum protection headroom.

Package differences exist: the 5KP120CA-TP uses R-6 axial configuration, while both substitutes employ P600 axial configuration. Through-hole mounting compatibility is maintained across all three devices. Packaging format (Tape & Reel versus Bulk) does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 15KPA120CA or 30KPA120CA be used as direct replacements for the 5KP120CA-TP?

A: Yes. Both substitute parts maintain identical reverse standoff voltage (120V), zener type classification, bidirectional channel configuration, and through-hole mounting. Clamping voltages remain within acceptable tolerance. Higher power ratings provide equivalent or superior transient protection.

Q: What is the significance of the different power ratings (5kW, 15kW, 30kW)?

A: Power rating indicates peak pulse dissipation capacity during transient events. Higher ratings accommodate greater transient energy without exceeding device thermal limits. Selection depends on the magnitude and frequency of transient pulses in the application circuit.

Q: Are the R-6 and P600 packages mechanically interchangeable?

A: Both are axial through-hole packages suitable for PCB mounting. Physical dimensions differ; verify PCB footprint compatibility before substitution. Electrical performance is independent of package geometry.

Q: Do packaging formats (Tape & Reel versus Bulk) affect device performance?

A: No. Packaging format is a logistics consideration only. Electrical and thermal characteristics remain identical regardless of supply format.

Q: Are all three devices suitable for the same operating temperature range?

A: Yes. All devices operate across -55°C to 175°C junction temperature, maintaining consistent performance throughout this range.

Q: What compliance certifications apply to these substitute parts?

A: All three devices are ROHS3 compliant and maintain active product status. REACH and ECCN classifications are consistent across the product group.
