5KP8.0AE3/TR13 Transient Voltage Suppressor (TVS) Diode

Part Overview

The 5KP8.0AE3/TR13 is an active-status Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose transient voltage protection applications. This unidirectional zener-type TVS diode features an 8V reverse standoff voltage with a 13.6V maximum clamping voltage and peak pulse current handling of 368A at 5000W peak pulse power. The device is packaged in a P600 axial through-hole configuration and is ROHS3 compliant with unlimited moisture sensitivity rating.

Alternative part sourcing becomes necessary due to inventory availability, supply chain considerations, or specific packaging requirements while maintaining equivalent electrical performance and operational characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5KP8.0AE3/TR13 is determined by strict equivalence across the following critical electrical parameters:

Voltage Parameters: Reverse standoff voltage of 8V, breakdown voltage minimum of 8.89V, and maximum clamping voltage of 13.6V must remain constant across all substitute parts.

Current and Power Ratings: The peak pulse current (10/1000µs) and peak pulse power dissipation capacity define the device's transient protection capability and must be matched or exceeded.

Device Type and Configuration: All substitutes must be unidirectional zener-type TVS diodes with single-channel configuration.

Environmental and Compliance Requirements: Operating temperature range of -55°C to 175°C (TJ), ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1) are mandatory for substitution eligibility.

Mounting and Packaging: Through-hole axial package configuration is required for mechanical and electrical compatibility in existing circuit designs.

The SA8.0A from Taiwan Semiconductor Corporation meets all voltage, type, channel, temperature, and compliance criteria. However, the peak pulse current rating of 38A and peak pulse power of 500W represent reduced transient protection capacity compared to the primary part's 368A and 5000W specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (5KP8.0AE3/TR13): This Microchip Technology device is the specified component for applications requiring 368A peak pulse current and 5000W peak pulse power dissipation. The P600 axial package provides the mechanical form factor for the original circuit design. Active product status and ROHS3 compliance ensure continued availability and regulatory conformance.

Substitute Part (SA8.0A): The Taiwan Semiconductor Corporation SA8.0A provides electrical equivalence in voltage parameters (8V standoff, 8.89V breakdown, 13.6V clamping) and maintains identical operating temperature range and compliance certifications. The DO-204AC (DO-15) axial package is mechanically compatible with through-hole mounting. However, the reduced peak pulse current (38A) and peak pulse power (500W) limit this substitute to applications with lower transient energy requirements. This part is suitable only when circuit design specifications permit reduced transient protection capacity.

Both parts maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring regulatory and environmental conformance across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can the SA8.0A directly replace the 5KP8.0AE3/TR13 in all applications?

A: The SA8.0A provides voltage-level equivalence (8V standoff, 13.6V clamping) and identical operating temperature range. However, the peak pulse current rating of 38A and peak pulse power of 500W are substantially lower than the primary part's 368A and 5000W specifications. Substitution is valid only for applications where circuit design specifications permit reduced transient protection capacity.

Q: Are the package configurations interchangeable?

A: Both devices use axial through-hole mounting. The 5KP8.0AE3/TR13 uses P600 packaging, while the SA8.0A uses DO-204AC (DO-15) packaging. Both packages are compatible with standard through-hole PCB layouts, though physical dimensions may differ. Verify PCB footprint compatibility before substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the 5KP8.0AE3/TR13 and SA8.0A are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both carry EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Q: What is the primary difference between these two TVS diodes?

A: The critical difference is transient protection capacity. The 5KP8.0AE3/TR13 handles 368A peak pulse current and 5000W peak pulse power, while the SA8.0A handles 38A peak pulse current and 500W peak pulse power. Voltage clamping characteristics remain identical. Select based on circuit transient energy requirements.

Q: Can I use the SA8.0A in a high-energy transient environment?

A: No. The SA8.0A's 500W peak pulse power rating is insufficient for applications requiring the 5KP8.0AE3/TR13's 5000W capacity. Using an undersized TVS diode in high-energy transient environments results in inadequate protection and potential device failure.

Q: Are there inventory or lead-time considerations for substitution?

A: The SA8.0A shows significantly higher inventory availability (300,300 pcs) compared to the 5KP8.0AE3/TR13 (987 pcs). Substitution may be driven by supply chain availability, though electrical and power rating differences must be evaluated first.
