SCS308AHGC9 Equivalent & Substitute Parts Reference

Part Overview

The SCS308AHGC9 from Rohm Semiconductor is a Silicon Carbide (SiC) Schottky diode in the Diodes, Rectifiers category, offering a reverse voltage rating of 650 V and average rectified current of 8A in a TO-220ACP through-hole package. This part provides high efficiency due to its negligible reverse recovery time and low forward voltage drop. The product is active and RoHS3 compliant, making it suitable for environmentally regulated designs.
Finding alternative models is essential in cases of supply chain disruptions, inventory depletion, or to accommodate second-source requirements where maintaining identical electrical and mechanical parameters—including package, mounting style, and compliance—is critical.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must match to consider a SiC Schottky diode as a valid substitute within the Diodes, Rectifiers category?
A1: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Reverse Recovery Time (trr), Mounting Type, Package / Case, RoHS Status, and Product Status.

Q2: How does package or mounting type impact substitutability?
A2: Substitute diodes must share a through-hole mounting style and comparable TO-220-2 or TO-220ACP case types to ensure mechanical and board-level compatibility.

Q3: Do substitutes with higher current ratings or slightly different forward voltages impact functional equivalence?
A3: If all key electrical limits are met or exceeded and package remains compatible, substitutes with equal or higher current ratings and minimal Vf deviation can be considered functionally equivalent according to the provided data.

Q4: Are compliance and product status criteria mandatory for selection?
A4: Yes, RoHS3 compliance and active product status are required to ensure regulatory adherence and ongoing supply availability per the information provided.

Q5: Is there any difference between using SCS308APC9 versus SCS308AHGC9 for form-fit-function?
A5: Both share identical electrical parameters per the dataset; only package suffixes differ according to information provided, which can impact mechanical mounting specifics if board layouts are package-dependent.
