SMLJ160CA-TP Equivalent & Substitute Parts Reference

Part Overview

The Micro Commercial Co SMLJ160CA-TP is an active transient voltage suppressor (TVS) diode designed for general purpose interface protection applications. It features a bidirectional Zener-type configuration in a DO-214AB (SMC) surface mount package, supporting a peak pulse power of 3000W (3kW) and a peak pulse current of 11.6A. Its voltage standoff is 160V with a maximum clamping voltage of 259V. Alternative models are necessary for production flexibility, supply chain resiliency, and to maintain continuous inventory availability in case of procurement constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution is permissible when the alternative device strictly matches key electrical and mechanical parameters of the main part number. The substitute, Alpha & Omega Semiconductor Inc SMDJ160CA, aligns with the following criteria: type (Zener), bidirectional channel count (1), reverse standoff voltage (160V), breakdown voltage (178V), clamping voltage (259V), peak pulse current (11.6A), peak pulse power (3000W), mounting type (surface mount), package (DO-214AB SMC), and application (general purpose). These shared parameters ensure compatibility within the transient voltage suppressor (TVS) product family for direct replacement.
