Innovations Embedded Silcon Carbide - Schottky Barrier Diodes Selection Guide SiC Schottky Barrier Diodes Selection Guide Choosing Silicon Carbide Instead of Silicon Schottky barrier diodes (SBDs) have the times higher, and a thermal coefficient This is certainly true for the most basic advantage of low forward losses and three times larger. These characteristics components negligible switching losses compared to make it ideal for power electronics diodes and transistors. Silicon carbide other diode technologies. But the narrow applications. Schottky barrier diodes have been bandgap of silicon (Si) SBDs limits their in power electronics: available for more than a decade but use to a maximum voltage of around Today, the need for higher efficiency have not been commercially viable until 200 V. Si diodes that operate above 200 in V have higher VF and trr. than Silicon carbide (SiC) is a compound improvements, semiconductor with superior power compound characteristics to silicon, including a deliver significantly better performance— bandgap approximately three times and in some cases not even possible greater, a dielectric breakdown field 10 with their silicon counterparts. end products ever. is Although more critical recently. Volume production is now silicon power leading to SiC's acceptance in more and products continue to see incremental devices based semiconductor on more applications. materials Legend Si Schottky Barrier Diode Si Super Fast Diode Si Ultra Fast Diode Si Fast Recovery (Epitaxial) Diode Si Standard Recovery Diode Silicon Carbide Schottky Barrier Diode 2 SiC Schottky Barrier Diodes Selection Guide 650V & 1200V Diodes ROHM's silicon carbide family of Schottky barrier diodes offers industry-leading low forward voltage and fast recovery time. They maintain low forward voltage (VF) over a wide operating temperature range which results in lower power dissipation under actual operating conditions. Low VF minimizes switching loss and enables high switching frequency, resulting in smaller passives and smaller end-product form factors. Applications Features /Advantages • Power Factor Correction/SMPS • • Solar Inverters Extremely low switching loss and reduced EMI emission due to much smaller recovery current • Motor Drives • High operating temperature and smaller losses greatly reduces heat sink requirement DESIGN NOTE SiC Performance Improvement over Si FRD With and SiC Schottky barrier diode (SBD), switching losses are reduced by 2/3 compared to a silicon fast recovery diode (FRD). (The Si FRD is used for comparison since it has a comparable voltage rating to the SiC SBD.) 3 SiC Schottky Barrier Diodes Selection Guide 2nd Generation Low VF SBD Product Lineup Non Automotive Grade IR (uA) Max PD (W) Pacakge 6 8 10 15 12 20 6 8 10 12 15 20 6 8 10 12 15 20 15 20 10/20* 15/30* 20/40* 5 10 15 20 5/10* 10/20* 15/30* 20/40* IFSM (A) Abs V (V) Typ Max @ 60Hz F 24 1.35 31 1.35 40 1.35 55 1.35 45 1.35 71 1.35 24 1.35 31 1.35 40 1.35 45 1.35 55 1.35 71 1.35 24 1.35 31 1.35 40 1.35 45 1.35 55 1.35 71 1.35 55 1.35 71 1.35 40/80* 1.35 55/110* 1.35 71/140* 1.35 23 1.4 45 1.4 65 1.4 82 1.4 23/46* 1.4 44/88* 1.4 65/130* 1.4 83/160* 1.4 120 160 200 300 240 400 120 160 200 240 300 400 120 160 200 240 300 400 300 400 200 300 400 100 200 300 400 100 200 300 400 48 62 83 100 88 100 51 68 78 93 110 130 31 34 34 37 39 40 110 130 160 230 270 88 150 180 210 170 280 360 420 LPTL (D2-PAK) LPTL (D2-PAK) LPTL (D2-PAK) LPTL (D2-PAK) LPTL (D2-PAK) LPTL (D2-PAK) TO-220AC TO-220AC TO-220AC TO-220AC TO-220AC TO-220AC TO-220FM TO-220FM TO-220FM TO-220FM TO-220FM TO-220FM TO-247 TO-247 TO-247 TO-247 TO-247 TO-220AC TO-220AC TO-220AC TO-220AC TO-247 TO-247 TO-247 TO-247 (V) Abs I (A) Part Number VR Max F SCS206AGHR 650 6 SCS208AGHR 650 8 SCS210AGHR 650 10 SCS212AGHR 650 12 SCS215AGHR 650 15 SCS220AGHR 650 20 SCS220AE2HR 650 10/20* SCS230AE2HR 650 15/30* SCS240AE2HR 650 20/40* SCS205KGHR 1200 5 SCS210KGHR 1200 10 SCS215KGHR 1200 15 SCS220KGHR 1200 20 SCS210KE2HR 1200 5/10* IFSM (A) Abs V (V) Typ Max @ 60Hz F 24 1.35 31 1.35 40 1.35 45 1.35 55 1.35 71 1.35 40/80* 1.35 55/110* 1.35 71/140* 1.35 23 1.4 45 1.4 65 1.4 82 1.4 23/46* 1.4 IR (uA) Max PD (W) Pacakge 120 160 200 400 240 300 200 300 400 100 200 300 400 100 51 68 78 93 110 130 160 124 270 88 150 180 210 170 TO-220AC TO-220AC TO-220AC TO-220AC TO-220AC TO-220AC TO-247 TO-247 TO-247 TO-220AC TO-220AC TO-220AC TO-220AC TO-247 200 280 TO-247 Part Number SCS206AJ SCS208AJ SCS210AJ SCS215AJ SCS212AJ SCS220AJ SCS206AG SCS208AG SCS210AG SCS212AG SCS215AG SCS220AG SCS206AM SCS208AM SCS210AM SCS212AM SCS215AM SCS220AM SCS215AE SCS220AE SCS220AE2 SCS230AE2 SCS240AE2 SCS205KG SCS210KG SCS215KG SCS220KG SCS210KE2 SCS220KE2 SCS230KE2 SCS240KE2 VR (V) Abs Max 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 650 1200 1200 1200 1200 1200 1200 1200 1200 IF (A) Equivalent Circuit *1 pin/package total Automotive Grade SCS220KE2HR 1200 10/20* 44/88* 1.4 *1 pin/package total 4 Equivalent Circuit ROHM Semiconductor 2323 Owen Street Santa Clara, CA 95054 www.rohm.com | 1.888.775.ROHM NOTE: For the most current product information, contact a ROHM sales representative in your area.
