ES5DB-HF Equivalent & Substitute Parts Reference Page

Part Overview

The ES5DB-HF (Comchip Technology) is a fast recovery standard rectifier diode designed for surface mount applications in SMB/DO-214AA packaging. It features a 200 V reverse voltage rating, 5 A average rectified current, and fast recovery performance. The part is currently active and available in inventory. When direct sourcing is constrained by availability, supply chain disruptions, or manufacturer discontinuation, engineering substitution is necessary to maintain functional circuit integrity while meeting design-electrical and mechanical requirements defined for this product category.

Substitute Part Grouping Explanation

Substitution within the diodes, rectifiers category is determined by strict matching of electrical and mechanical parameters. The following key parameters must align for equivalency: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Reverse Recovery Time (trr), Mounting Type, Package / Case, and Operating Temperature - Junction. ROHS3 compliance status is also required for selection. Substitute part ES5DB (MDD) meets these criteria within defined tolerances and classifications for this product category.
