Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP58CA-G are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 58V
• Bidirectional Channels: 1
• Mounting Type: Through Hole
• Type: Zener
• Applications: General Purpose

Allowable Variation Parameters:

• Voltage - Clamping (Max) @ Ipp: ±2V tolerance acceptable
• Current - Peak Pulse (10/1000µs): Higher ratings acceptable for enhanced protection
• Power - Peak Pulse: Higher ratings acceptable for enhanced protection
• Operating Temperature: Extended range acceptable
• Package / Case: Alternative axial through-hole packages acceptable

The identified substitutes (15KPA58CA and 30KPA58CA) maintain the critical 58V standoff voltage specification while offering increased peak pulse current and power dissipation capabilities. Both substitutes are manufactured by MDE Semiconductor Inc and retain through-hole axial mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full RoHS3 compliance, ensuring regulatory alignment for current applications. The 5KP58CA-G remains the baseline specification with 5kW peak pulse power handling. The 15KPA58CA and 30KPA58CA provide enhanced current and power dissipation capabilities while maintaining the critical 58V reverse standoff voltage specification. Selection between these options depends on application peak pulse current requirements and thermal management constraints. The substitute parts feature extended operating temperature ranges (-55°C to 175°C versus -55°C to 150°C), providing additional margin in high-temperature environments. Package differences (R-6 versus P600 axial) require PCB layout verification for mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can 15KPA58CA or 30KPA58CA be used as direct replacements for 5KP58CA-G?

A: Yes, both parts maintain the critical 58V reverse standoff voltage and through-hole axial mounting configuration. The higher peak pulse current ratings (161A and 327.9A respectively) provide equivalent or enhanced protection. Physical package differences (P600 versus R-6) require PCB layout verification.

Q: What is the significance of the different peak pulse current ratings?

A: Peak pulse current rating indicates the maximum transient current the device can suppress. The 5KP58CA-G handles 53.42A, while 15KPA58CA handles 161A and 30KPA58CA handles 327.9A. Higher ratings provide protection margin for applications with larger transient events.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The 5KP58CA-G uses R-6 axial package while both substitutes use P600 axial package. Although both are through-hole axial configurations, physical dimensions differ. PCB footprint and lead spacing must be verified before substitution.

Q: Do the substitute parts maintain compliance certifications?

A: Yes. All three parts are RoHS3 compliant and carry active product status. The substitute parts from MDE Semiconductor Inc maintain equivalent regulatory standing.

Q: What is the impact of extended operating temperature range on part selection?

A: The substitute parts operate to 175°C junction temperature versus 150°C for the 5KP58CA-G. This extended range provides additional thermal margin in high-temperature applications but does not affect electrical performance at standard operating conditions.
