Each diode is rated for 15 A average rectified current with a maximum forward voltage of 470 mV at that current — this is the conduction loss floor for the rectifier stage. The 45 V reverse voltage rating and 600 µA reverse leakage at 45 V define the standby loss ceiling, making the part a fit for output rectification in 12 V and 24 V bus converters where every millivolt of drop eats into efficiency. ## 175°C junction — thermal headroom for enclosed supplies Rated for a maximum junction temperature of 175°C, the FERD30M45CT can run in high-ambient enclosures — think power supplies, motor drives, or industrial SMPS — without derating the 15 A per diode. The fast recovery classification (≤500 ns at >200 mA) keeps switching losses manageable in the 50–100 kHz range, so the part pulls double duty as both a line-frequency rectifier and a high-efficiency output diode. Sourced through standard distribution — quoted to order against the BOM quantity.","metaTitle":"STMicro FERD30M45CT FERD Diode Array, 45V 15A TO-220","metaDescription":"STMicroelectronics FERD30M45CT dual common-cathode rectifier: 45V Vr, 15A per diode, 470mV Vf at 15A, 175°C Tj max.

Where a Schottky's leakage climbs sharply above 100°C, the FERD maintains a tighter leakage profile, making it a better fit for high-temperature rectifier stages where standby loss matters."},{"question":"Can I use FERD30M45CT as a replacement for STPS30L45CT?","answer":"Both are dual common-cathode 45 V, 15 A per diode rectifiers in TO-220, so the pinout and basic ratings align. The FERD30M45CT uses FERD technology versus the STPS30L45CT's Schottky barrier — the key trade-off is leakage versus switching speed. If the original design relied on the Schottky's lower capacitance at high frequency, bench-verify the recovery behaviour. For 50–100 kHz SMPS output stages the FERD is a functional cross, but confirm the thermal and switching margins in your specific circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/FERD30M45CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/FERD30M45CT when reusing this data.
