BAT54AHMT116 Equivalent & Substitute Parts Reference Page

Part Overview

The Rohm Semiconductor BAT54AHMT116 is a surface mount Schottky diode array in the category of diodes and rectifiers. It features a 1 pair common anode configuration rated at 30 V reverse voltage and 200 mA average rectified current per diode. The component is supplied in TO-236-3, SC-59, SOT-23-3 packages with a maximum forward voltage of 800 mV at 100 mA, and a reverse recovery time of 50 ns. The BAT54AHMT116 is marked as active and available in new original stock. Identifying alternative models is necessary for scenarios such as maintaining supply continuity, enabling automotive qualification, or matching specific packaging formats, while ensuring compliance and equivalency in electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitutes for the BAT54AHMT116 are selected strictly according to the following key parameters: diode configuration (1 Pair Common Anode), Schottky technology, maximum DC reverse voltage (30 V), average rectified current per diode (200mA), forward voltage at specified current (800 mV @ 100 mA), reverse recovery time (50 ns), reverse leakage current (2 µA @ 25 V), operating junction temperature (150°C), mounting type (Surface Mount), and mechanical package (TO-236-3, SC-59, SOT-23-3). Compliance standards such as RoHS3 and REACH as well as product status (Active) are required for direct substitution. No substitute is listed outside these boundaries.
