Each of the two diodes is rated for 15 A average rectified current at a 45 V reverse voltage, with a forward voltage of 470 mV typical at that current. The common-cathode configuration makes it a direct fit for centre-tap secondary rectification in a push-pull or half-bridge converter, or as a pair of OR-ing diodes in a redundant power rail. ## No Recovery Time — what the speed rating actually means The 'No Recovery Time > 500 mA (Io)' spec means the diode exhibits negligible reverse recovery charge when switching from a forward current of 500 mA or less. In practice, this makes the part suited for the output stage of a switching power supply operating at 100 kHz or above, where a conventional ultrafast rectifier would still generate recovery losses. The FERD structure achieves this by limiting the minority carrier storage, giving a softer turn-off characteristic than a standard Schottky of the same voltage class. ## D²PAK package — thermal and footprint reality The D²PAK (TO-263AB) package is a surface-mount power package with a large exposed copper tab on the bottom. The tab is the cathode common terminal for both diodes, so the PCB copper area under the tab directly sets the junction-to-ambient thermal resistance. For a 30 A total output (15 A per die), the board needs a minimum of 6 cm² of 2-oz copper on the tab pad to keep the junction below 125 °C in still air. The package is rated for a maximum junction temperature of 175 °C, which provides headroom for surge conditions. No official second source or pin-compatible replacement is listed by ST, but the common-cathode D²PAK footprint is a standard pinout shared by many dual Schottky and FERD rectifiers in the 30 A class.","metaTitle":"ST FERD30M45CG-TR Diode Array, 45V 15A D²PAK","metaDescription":"ST FERD30M45CG-TR dual common-cathode rectifier: 45V Vr, 15A per diode, 470mV Vf at 15A.

The key difference is technology: the FERD part uses a Field Effect Rectifier structure that gives a lower forward voltage (470 mV vs ~550 mV typical for the Schottky at 15 A) and a softer recovery characteristic, at the expense of slightly higher reverse leakage at elevated temperatures. For high-frequency output rectification where conduction loss dominates, the FERD part is the better choice; for applications requiring lower leakage at high junction temperature, the Schottky variant may be pre"},{"question":"Is FERD30M45CG-TR suitable for high frequency applications?","answer":"Yes. The 'No Recovery Time > 500 mA (Io)' rating indicates negligible reverse recovery charge at moderate forward currents, which makes the diode suited for switching frequencies above 100 kHz where recovery losses in a standard PN or even some Schottky diodes would degrade efficiency. The FERD structure is designed for soft recovery in high-frequency power supplies."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/FERD30M45CG-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/FERD30M45CG-TR when reusing this data.
