The 100 V reverse voltage gives headroom for 48 V telecom rectifiers, 24 V industrial power supplies, and 12 V automotive alternator loads. Junction temperature is rated up to 175°C, which matters when the rectifier sits near a hot transformer or in a sealed enclosure. ## 770 mV forward drop at 10 A — thermal budget driver At 10 A per diode the forward drop is 770 mV, so each diode dissipates about 7.7 W in conduction. The D2PAK's exposed tab carries most of that heat to the PCB copper plane. If you are running both diodes near full current, the total dissipation hits 15.4 W — that needs a solid thermal via pattern under the tab and at least 2 oz copper on the top layer. The 175°C junction rating gives some margin, but the tab temperature is what limits continuous output. Reverse leakage is 4.5 µA at 100 V, low enough that it does not add meaningful loss in offline supplies. STMicroelectronics lists the STPS20H100CG as Active. That means no last-time-buy clock is running, and the part is still a standard production item through normal distribution. If you are stocking spares, the D2PAK reels store well — MSL 1 typically, so no bake required before reflow as long as the bag seal is intact.","metaTitle":"STPS20H100CG Schottky Diode, 2x10A 100V D2PAK","metaDescription":"STPS20H100CG dual Schottky rectifier: 100 V, 10 A per diode, 770 mV Vf, 175°C junction.

The key difference is the forward voltage: the L version uses a low-drop Schottky technology with a lower Vf at the expense of higher reverse leakage. If your design is thermally constrained and can tolerate the leakage, the L variant is worth evaluating for a dual-source option."},{"question":"Is STPS20H100CG RoHS compliant?","answer":"The STPS20H100CG is listed as RoHS compliant per STMicroelectronics' standard product marking. No exemption declarations are noted on the product page."},{"question":"How to test STPS20H100CG diode?","answer":"A standard diode-check on a multimeter will show the Schottky junction forward voltage, typically around 0.3 V to 0.4 V at low test current. For a full functional check, apply 10 A forward current and measure the forward voltage against the 770 mV maximum at 25°C junction temperature. Reverse leakage at 100 V should be under 4.5 µA. The common-cathode configuration means the tab is the cathode — test between each anode pin and the tab."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS20H100CG","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS20H100CG when reusing this data.
