Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP51CE3/TR13 are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff (Typ): 51V (exact match required)
• Voltage - Breakdown (Min): 56.7V to 57V range
• Voltage - Clamping (Max) @ Ipp: 82.4V to 91.1V range
• Operating Temperature Range: -55°C to 175°C (minimum requirement)
• Type: Zener, Bidirectional (1 channel)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: P600 or R-6 axial configurations
• Applications: General Purpose

Compliance Criteria:

• RoHS3 Compliant
• MSL: 1 (Unlimited)

The substitute parts 5KP51CA-TP and 30KPA51CA meet these criteria with variations in peak pulse current and power dissipation ratings, which represent enhanced or equivalent performance characteristics within the same voltage class and package family.

Parameter Comparison

Engineering Selection Recommendations

5KP51CA-TP (Micro Commercial Co): This substitute maintains electrical equivalence with the main part across all critical voltage parameters. The clamping voltage of 82.4V is lower than the main part's 91.1V, providing improved transient suppression performance. Both devices share identical power dissipation ratings (5000W) and operating temperature ranges. The R-6 package is mechanically compatible with P600 applications in through-hole mounting configurations. This part is ROHS3 compliant with unlimited MSL rating and active product status, supporting long-term design continuity.

30KPA51CA (MDE Semiconductor Inc): This substitute provides enhanced performance characteristics with significantly higher peak pulse current (350.7A) and power dissipation (30000W) compared to the main part. The voltage parameters remain within acceptable ranges: 51V reverse standoff, 57V breakdown minimum, and 86.4V clamping maximum. The P600 package matches the main part exactly. This device is suitable for applications requiring higher transient energy absorption while maintaining the same voltage class. ROHS3 compliance and unlimited MSL rating are maintained. Active product status ensures availability.

Both substitutes are qualified for general-purpose transient voltage suppression applications and maintain full compliance with RoHS3 and moisture sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5KP51CA-TP be used as a direct replacement for the 5KP51CE3/TR13?

A: The 5KP51CA-TP is electrically compatible within the 51V voltage class. The primary difference is the package type: R-6 axial versus P600 axial. Both are through-hole configurations. The clamping voltage of 82.4V is lower, providing enhanced suppression. Verify board layout compatibility with the R-6 package footprint before substitution.

Q: What is the advantage of using the 30KPA51CA over the main part?

A: The 30KPA51CA provides significantly higher peak pulse current (350.7A) and power dissipation (30000W) compared to the 5KP51CE3/TR13 (54.9A, 5000W). This makes it suitable for applications with higher transient energy requirements. The voltage parameters remain equivalent at 51V reverse standoff. The P600 package is identical to the main part.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 5KP51CE3/TR13, 5KP51CA-TP, and 30KPA51CA are all ROHS3 compliant with MSL rating of 1 (Unlimited), meeting environmental and regulatory requirements for industrial and commercial applications.

Q: What is the difference between P600 and R-6 packages?

A: Both P600 and R-6 are axial through-hole package types for TVS diodes. The R-6 package used in the 5KP51CA-TP has different physical dimensions compared to the P600 package. Verify PCB footprint compatibility and lead spacing before selecting the R-6 variant.

Q: Can the 30KPA51CA be used in applications designed for the 5KP51CE3/TR13?

A: Yes. The 30KPA51CA maintains the same 51V voltage class and operating temperature range. The higher power rating (30kW versus 5kW) makes it suitable for the same applications with enhanced margin. The P600 package is identical, ensuring direct mechanical compatibility.

Q: What operating temperature range do all three parts support?

A: All three parts operate across -55°C to 175°C (TJ), providing equivalent thermal performance for industrial and automotive applications.

Q: Are there any inventory considerations for these substitutes?

A: The 5KP51CE3/TR13 has 691 pieces in stock, the 5KP51CA-TP has 1520 pieces, and the 30KPA51CA has 2053 pieces available. Substitute parts offer higher inventory availability for supply chain flexibility.
