SLD26CA-TP Equivalent & Substitute Parts Reference

Part Overview

The SLD26CA-TP is a 26V Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for interface protection applications. This bidirectional Zener-type TVS diode operates across an automotive-grade temperature range of -55°C to 175°C and is currently in active production status. The part is supplied in bulk packaging with R-6 axial through-hole mounting configuration.

Substitute parts are identified when equivalent electrical performance can be maintained within the specified voltage and current parameters while accommodating different power ratings, package variants, or supplier availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SLD26CA-TP are qualified based on the following electrical and mechanical criteria:

Voltage Parameters: All substitute parts maintain the 26V reverse standoff voltage specification with breakdown voltages within the 28.9V to 29.04V range. Clamping voltages remain within acceptable limits (42.1V to 44.7V).

Current and Power Ratings: Substitute parts are grouped by peak pulse current capacity and power dissipation. The SLD26CA-TP operates at 142A peak pulse with 6kW power rating. Substitutes with equal or higher current/power ratings provide direct replacement capability.

Mounting and Package: All substitute parts utilize through-hole axial mounting. Package variants (R-6 vs. P600) are noted as mechanical differences that may affect board layout compatibility.

Temperature Range: All parts operate across -55°C to 175°C (with 5KP26CA at -50°C minimum), meeting automotive-grade thermal requirements.

Product Status and Compliance: All parts maintain active production status. Compliance certifications (RoHS3, REACH status) are documented for each substitute.

Parameter Comparison

Engineering Selection Recommendations

5KP26CA (Diotec Semiconductor): This part provides equivalent voltage clamping (42.1V) and breakdown characteristics to the SLD26CA-TP. Peak pulse current is 119A, which is 16% lower than the main part. Power dissipation is 5000W, representing a 17% reduction. This substitute is suitable for applications where the lower current/power rating is acceptable. The part is RoHS3 compliant and supplied in Tape & Reel packaging. Operating temperature minimum is -50°C versus -55°C for the main part. Package variant is P600 (axial) rather than R-6.

15KPA26CA (MDE Semiconductor Inc): This part maintains the 26V standoff voltage with clamping voltage of 44V. Peak pulse current is 343.2A (141% higher than main part) with 15000W power rating (150% higher). This substitute provides enhanced transient protection capability. The part is RoHS3 compliant with MSL rating of 1 (Unlimited). Operating temperature range matches the main part (-55°C to 175°C). Package variant is P600 (axial).

20KPA26CA (MDE Semiconductor Inc): This part maintains the 26V standoff voltage with clamping voltage of 44.7V. Peak pulse current is 451.9A (218% higher than main part) with 20000W power rating (233% higher). This substitute provides maximum transient protection capability within the 26V class. The part is RoHS3 compliant and REACH Unaffected. Operating temperature range matches the main part (-55°C to 175°C). Package variant is P600 (axial).

All substitute parts maintain active production status and automotive-grade thermal specifications. Selection between substitutes depends on application transient energy requirements and board layout constraints related to package geometry differences.

Frequently Asked Questions (FAQ)

Q: Can the 5KP26CA replace the SLD26CA-TP in all applications?

A: The 5KP26CA maintains identical voltage clamping (42.1V) and breakdown characteristics. However, peak pulse current is 119A compared to 142A for the main part, and power dissipation is 5000W versus 6000W. Substitution is valid only when application transient currents do not exceed 119A. The operating temperature minimum is -50°C rather than -55°C. Package geometry differs (P600 vs. R-6), requiring board layout verification.

Q: What is the difference between the 15KPA26CA and 20KPA26CA substitutes?

A: Both parts maintain the 26V standoff voltage specification. The 15KPA26CA provides 343.2A peak pulse current and 15000W power dissipation. The 20KPA26CA provides 451.9A peak pulse current and 20000W power dissipation. The 20KPA26CA offers 32% higher current handling and 33% higher power rating. Selection depends on the magnitude of transient energy in the application circuit. Both use P600 package geometry.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 5KP26CA, 15KPA26CA, and 20KPA26CA are all RoHS3 compliant. The main part SLD26CA-TP does not specify RoHS status in the provided data.

Q: Does package geometry affect electrical performance?

A: No. Package geometry (R-6 vs. P600) affects physical board layout and mounting footprint only. Electrical performance is determined by the die and internal construction. However, board layout compatibility must be verified before substitution.

Q: Can I use a higher power-rated substitute in place of the SLD26CA-TP?

A: Yes. The 15KPA26CA and 20KPA26CA provide higher peak pulse current and power ratings while maintaining the 26V voltage class. These substitutes provide equal or enhanced protection. Electrical compatibility is maintained. Physical package differences must be accommodated in board design.

Q: What is the temperature range difference between substitutes?

A: The SLD26CA-TP and both MDE parts (15KPA26CA, 20KPA26CA) operate from -55°C to 175°C. The 5KP26CA operates from -50°C to 175°C, with a 5°C higher minimum temperature limit. This difference is significant only in applications requiring operation below -50°C.

Q: Are there inventory considerations for substitute selection?

A: Inventory levels are provided for reference. The 5KP26CA has 4100 units in stock, the 15KPA26CA has 1903 units, and the 20KPA26CA has 1629 units. The main part SLD26CA-TP has 923 units. Availability should be confirmed with the supplier for production requirements.
