1.5KE100A-TP Transient Voltage Suppressor Equivalent & Substitute Parts

Part Overview

The 1.5KE100A-TP is an active Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This unidirectional Zener diode operates in the 85.5V reverse standoff voltage range with a 137V maximum clamping voltage and 1500W peak pulse power rating. The component is housed in a DO-201AE axial through-hole package and maintains active product status with full ROHS3 compliance. Substitute parts are identified based on matching electrical characteristics and mechanical compatibility within the TVS diode category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1.5KE100A-TP are qualified based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85V to 85.5V
• Voltage - Clamping (Max) @ Ipp: 137V
• Type: Zener, Unidirectional
• Mounting Type: Through Hole, Axial package
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

The 1.5KE100A from Taiwan Semiconductor Corporation matches all primary electrical specifications and maintains identical voltage ratings and clamping characteristics. The 5KP85A from Diotec Semiconductor provides equivalent voltage protection with higher peak pulse power (5000W) and peak pulse current (36A), suitable for applications requiring enhanced transient energy dissipation while maintaining the same clamping voltage profile.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, qualifying them for equivalent substitution in general-purpose transient voltage suppression applications.

The 1.5KE100A from Taiwan Semiconductor Corporation provides direct electrical and mechanical equivalence to the 1.5KE100A-TP, with identical voltage ratings and power dissipation characteristics. This part is suitable for direct replacement in existing designs without circuit modification.

The 5KP85A from Diotec Semiconductor offers enhanced transient energy handling with 5000W peak pulse power and 36A peak pulse current, compared to 1500W and unspecified current in the primary part. This higher power rating accommodates applications with more severe transient events while maintaining the same 137V clamping voltage. The P600 package differs from the DO-201AE, requiring mechanical board layout verification for footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 1.5KE100A from Taiwan Semiconductor Corporation be used as a direct replacement for the 1.5KE100A-TP?

A: Yes. Both parts share identical voltage specifications (85.5V reverse standoff, 137V clamping), equivalent power ratings (1500W), and matching operating temperature ranges (-55 to 175°C). Both are ROHS3 compliant and housed in compatible axial through-hole packages (DO-201AA/DO-27 versus DO-201AE).

Q: When should the 5KP85A be selected over the 1.5KE100A-TP?

A: The 5KP85A is selected when the application requires higher transient energy dissipation. With 5000W peak pulse power and 36A peak pulse current, it handles more severe overvoltage events while maintaining the same 137V clamping voltage. The reverse standoff voltage is 85V, which is within acceptable tolerance of the 85.5V specification.

Q: Are there package compatibility concerns with the 5KP85A?

A: Yes. The 5KP85A uses a P600 axial package, while the 1.5KE100A-TP uses DO-201AE. Physical dimensions and lead spacing differ between these packages. Board layout and footprint must be verified before substitution.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. The 1.5KE100A and 5KP85A are both ROHS3 compliant. The 1.5KE100A maintains REACH Unaffected status matching the primary part. The 5KP85A lists REACH information as available upon request.

Q: What is the minimum operating temperature difference between parts?

A: The 5KP85A operates from -50°C, while the 1.5KE100A-TP and 1.5KE100A operate from -55°C. For applications requiring -55°C operation, the 5KP85A is not suitable without thermal analysis confirmation.
