Engineering Selection Recommendations

Direct Equivalent (Preferred Substitutes):

The 5KP22A-E3/54 (Vishay General Semiconductor) is a direct electrical and mechanical equivalent to the 5KP22AE3/TR13. Both devices share identical voltage ratings (22V standoff, 35.5V clamping), current capability (141A peak pulse), power dissipation (5000W), operating temperature range (-55°C to 175°C), and P600 axial package configuration. Both are RoHS3 compliant and carry Active product status. This part is available in Cut Tape packaging with 2866 units in stock.

The 5KP22A (Diotec Semiconductor) provides full electrical equivalence with matching voltage and current specifications, identical 5000W power rating, and P600 package compatibility. Operating temperature range is -50°C to 175°C (slightly narrower at the lower end). RoHS compliance status is not applicable for this manufacturer variant. This part is available with 8804 units in stock.

The 5KP22A-TP (Micro Commercial Co) matches all critical electrical parameters with 22V standoff, 35.5V clamping, and 5000W power rating. Package configuration is R-6 axial (alternative axial format). Peak pulse current specification is not provided in available data. RoHS3 compliant with -55°C to 175°C operating range. This part is available with 1494 units in stock.

Similar Substitutes (Reduced Performance):

The LCE22A (Littelfuse Inc.) matches voltage specifications (22V standoff, 35.5V clamping) but provides reduced peak pulse current (42A versus 141A) and lower power dissipation (1500W versus 5000W). Package is DO-201 axial format. RoHS3 compliant with full -55°C to 175°C operating range. Use only when circuit requirements permit lower current handling capability.

The 1.5KE27A (Taiwan Semiconductor Corporation) provides similar voltage protection with slightly elevated standoff voltage (23.1V) and clamping voltage (37.5V). Peak pulse current is significantly reduced to 42A with 1500W power rating. Package is DO-201 axial format. RoHS3 compliant with -55°C to 175°C operating range. Use only when circuit requirements permit lower current handling capability and slightly higher voltage thresholds.

Not Recommended:

The P6KE22A (Fairchild Semiconductor) exhibits insufficient electrical performance for direct substitution. Standoff voltage is 18.8V (below the 22V requirement), clamping voltage is 30.6V (below 35.5V requirement), peak pulse current is 20A (significantly below 141A requirement), and power dissipation is 600W (below 5000W requirement). Package is DO-15 axial format. This part is suitable only for applications with substantially lower voltage and current requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5KP22A-E3/54 (Vishay) be used as a direct replacement for the 5KP22AE3/TR13 (Microchip)?

A: Yes. The 5KP22A-E3/54 is a direct electrical and mechanical equivalent. Both devices feature identical 22V reverse standoff voltage, 35.5V clamping voltage, 141A peak pulse current, 5000W power dissipation, -55°C to 175°C operating temperature range, P600 axial package, and RoHS3 compliance. The only difference is packaging format (Cut Tape versus Tape & Reel) and manufacturer.

Q: What is the difference between the P600 package and the R-6 package used by the 5KP22A-TP?

A: Both P600 and R-6 are axial through-hole package formats for TVS diodes. The R-6 package is an alternative axial configuration. Physical dimensions and lead spacing may differ, requiring verification against PCB layout specifications. Electrical performance is identical between these package variants.

Q: Why does the LCE22A have lower peak pulse current (42A) compared to the 5KP22AE3/TR13 (141A)?

A: The LCE22A is a different product line within the TVS diode category, designed for lower-current transient suppression applications. While voltage ratings are identical, the internal die design and power dissipation capability (1500W versus 5000W) limit peak pulse current handling. Selection between these parts depends on actual circuit transient current requirements.

Q: Can the P6KE22A be used as a substitute for the 5KP22AE3/TR13?

A: No. The P6KE22A does not meet the electrical specifications of the 5KP22AE3/TR13. The P6KE22A has a lower standoff voltage (18.8V versus 22V), lower clamping voltage (30.6V versus 35.5V), significantly lower peak pulse current (20A versus 141A), and lower power dissipation (600W versus 5000W). This part is suitable only for applications with substantially different voltage and current protection requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Most substitute parts listed are RoHS3 compliant (5KP22A-E3/54, 1.5KE27A, 5KP22A-TP, LCE22A). The 5KP22A (Diotec) has RoHS compliance status listed as "Not applicable," and the P6KE22A compliance status is not specified. Verify RoHS compliance requirements for your specific application before final part selection.

Q: What is the operating temperature range difference between the 5KP22AE3/TR13 and the 5KP22A (Diotec)?

A: The 5KP22AE3/TR13 operates from -55°C to 175°C, while the 5KP22A (Diotec) operates from -50°C to 175°C. The Diotec variant has a narrower lower temperature limit by 5°C. For applications requiring operation below -50°C, the Microchip or Vishay variants are required.

Q: How do I determine which substitute part is appropriate for my circuit?

A: Selection is based on three criteria: (1) Voltage requirements—the device standoff voltage must match or exceed the circuit's normal operating voltage, and clamping voltage must protect downstream components; (2) Current requirements—peak pulse current must equal or exceed the maximum transient current expected in the circuit; (3) Package compatibility—the through-hole axial package must fit the PCB layout. Compare these three parameters against your circuit specifications and select the part with matching or superior ratings.

Q: Is the 5KP22A-TP suitable for use if peak pulse current is not specified?

A: The 5KP22A-TP lists peak pulse current as not provided in available data. However, all other electrical parameters (22V standoff, 35.5V clamping, 5000W power) match the 5KP22AE3/TR13 exactly, suggesting equivalent current capability. Contact the manufacturer (Micro Commercial Co) to confirm peak pulse current specification before final selection if this parameter is critical to your application.
