5KP170AE3/TR13 Equivalent & Substitute Parts
Part Overview
The 5KP170AE3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This component features a 170V reverse standoff voltage with a 275V maximum clamping voltage and 18.5A peak pulse current capability. The device is classified as active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts are necessary when specific packaging requirements, manufacturer preferences, or inventory constraints necessitate component substitution while maintaining electrical performance specifications.

Substitute Part Grouping Explanation
Substitution of the 5KP170AE3/TR13 is determined by electrical parameter compatibility within the transient voltage suppressor category. The critical parameters governing substitution are: reverse standoff voltage (170V nominal), breakdown voltage minimum (189V), maximum clamping voltage (275V), peak pulse current (18.5A), and peak pulse power (5000W). All substitute parts must maintain these electrical specifications to ensure equivalent circuit protection performance.
The substitute parts are grouped into two categories:
Direct Electrical Equivalent: The 5KP170A from Littelfuse Inc. provides identical electrical specifications across all critical parameters, differing only in packaging format (Cut Tape versus Tape & Reel) and manufacturer identity.
Similar Electrical Performance: The P6KE180A and P6KE200A from Fairchild Semiconductor provide comparable voltage suppression characteristics with reverse standoff voltages of 154V and 171V respectively, and clamping voltages of 246V and 274V respectively. These parts operate at significantly reduced peak pulse current (2.5A and 2.2A) and power dissipation (600W), making them suitable for lower-energy transient protection applications.
Non-Equivalent Component: The PKC-136 from Diotec Semiconductor is categorized as a diode array rather than a TVS diode and does not provide equivalent electrical performance for transient voltage suppression applications.

Engineering Selection Recommendations
5KP170A (Littelfuse Inc.) is the direct electrical equivalent for the 5KP170AE3/TR13. This part maintains identical electrical specifications and is RoHS3 compliant. Selection of this substitute is appropriate when Littelfuse sourcing is preferred or when Cut Tape packaging is acceptable in place of Tape & Reel format. Both parts are active product status with unlimited moisture sensitivity rating.
P6KE180A and P6KE200A (Fairchild Semiconductor) are suitable substitutes only for applications requiring lower peak pulse current and power dissipation. These parts operate at 2.5A and 2.2A respectively, compared to the 18.5A specification of the primary part. Selection of these alternatives is appropriate when circuit design accommodates reduced transient energy handling capability. Operating temperature range is -50 to 175°C, which is narrower than the -55 to 175°C range of the primary part.
PKC-136 (Diotec Semiconductor) is not an equivalent substitute. This component is classified as a diode array rather than a transient voltage suppressor and does not provide the required electrical performance characteristics for TVS applications.
Component selection should be based on application-specific transient energy requirements, packaging constraints, and manufacturer availability. All recommended substitutes maintain through-hole axial mounting configuration.
Frequently Asked Questions (FAQ)
Q: Can the 5KP170A directly replace the 5KP170AE3/TR13 in existing circuit designs?
A: Yes. The 5KP170A provides identical electrical specifications including 170V reverse standoff voltage, 275V clamping voltage, and 18.5A peak pulse current. The primary difference is packaging format (Cut Tape versus Tape & Reel). Both parts are RoHS3 compliant and rated for -55 to 175°C operating temperature.
Q: What is the difference between the P6KE180A/P6KE200A and the primary 5KP170AE3/TR13 part?
A: The P6KE series parts operate at significantly reduced peak pulse current (2.5A and 2.2A versus 18.5A) and power dissipation (600W versus 5000W). These parts are suitable only for lower-energy transient protection applications. The P6KE180A has a 154V reverse standoff voltage, while the P6KE200A has 171V, both differing from the 170V specification of the primary part.
Q: Are the P6KE180A and P6KE200A suitable for high-energy transient suppression applications?
A: No. These parts are rated for 600W peak pulse power compared to 5000W for the 5KP170AE3/TR13. Selection of these alternatives is appropriate only when circuit design accommodates reduced transient energy handling capability.
Q: What is the package difference between the 5KP170AE3/TR13 and 5KP170A?
A: The 5KP170AE3/TR13 is supplied in Tape & Reel (TR) packaging, while the 5KP170A is supplied in Cut Tape (CT) packaging. Both use the P600 axial package case. Package selection depends on assembly process requirements and inventory management practices.
Q: Is the PKC-136 a suitable substitute for the 5KP170AE3/TR13?
A: No. The PKC-136 is classified as a diode array rather than a transient voltage suppressor diode. It does not provide equivalent electrical performance for TVS applications and is not a valid substitute.
Q: What compliance certifications are maintained across substitute parts?
A: The 5KP170AE3/TR13 and 5KP170A are both RoHS3 compliant with REACH Unaffected status. The P6KE180A and P6KE200A compliance status is not specified in available documentation. All parts are classified under ECCN EAR99.
Q: Can the operating temperature range difference between parts affect substitution decisions?
A: The 5KP170AE3/TR13 and 5KP170A operate across -55 to 175°C, while the P6KE180A and P6KE200A operate across -50 to 175°C. For applications requiring operation below -50°C, the P6KE series parts are not suitable substitutes.
