SDH SERIES CRD_Datasheet SDH SERIES CRD DESCRIPTION SDH series current regulative diode (CRD) is based on Silan’s planar JFET process. It features low start-up stabilized current supply voltage, stable constant-current characteristics and high forward breakdown voltage for its advanced process and smart design. SDH series CRD has powerful anti-interference capacity of surge current between the anode and cathode, and no other assistant components are needed in application. SDH series CRD supplies.

SDH SERIES CRD_Datasheet SDH SERIES CRD DESCRIPTION SDH series current regulative diode (CRD) is based on Silan’s planar JFET process. It features low start-up stabilized current supply voltage, stable constant-current characteristics and high forward breakdown voltage for its advanced process and smart design. SDH series CRD has powerful anti-interference capacity of surge current between the anode and cathode, and no other assistant components are needed in application. SDH series CRD supplies constant current to an electric circuit and is widely used in the constant-current LED driver, modules in phone circuitry, etc. It is available in SOD-123, SOT-223-3L and TO-92-3L packages. FEATURES ∗ Low start-up stabilized current supply voltage ∗ High dynamic impedance ∗ Constant-current range: 1mA-40mA. ∗ Be paralleled for current extension. ∗ Negative temperature coefficient for LED protection under high temperature NOMENCLATURE ORDERING INFORMATION Part No. SDHXXXSTR SDHXXXHTR SDHXXXBTR Package SOD-123 SOT-223-3L TO-92-3L Marking XXXS SDHXXXH XXXB Material Pb free Pb free Pb free Packing Tape&Reel Tape&Reel AMMO HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http://www.silan.com.cn REV:1.1 2011.01.05 Page 1 of 7 SDH SERIES CRD_Datasheet ABSOLUTE MAXIMUM RATINGS (Unless otherwise specified, Tc=25°C) Characteristics Power Dissipation Chip-To-Ambient Thermal Resistance Maximum Operating Voltage Operating And Storage Junction Temperature Symbol PD RθJA Vmax Tstg Range SOD-123 350 TO-92-3L 200 SOT-223-3L 100 300 See the table below -30~+150 Unit mW mW mW °C/W V °C ELECTRICAL CHARACTERISTICS (Unless otherwise specified, TC=25°C) Specifica -tion Constant current rangenote Test voltage Ip(mA) 102 10V 0.88~1.32 152 10V 1.28~1.72 202 10V 1.68~2.32 272 10V 2.28~3.10 352 10V 3.00~4.10 452 10V 3.90~5.10 562 10V 5.00~6.50 822 10V 6.56~9.84 103 10V 8~12 123 10V 9.6~14.4 153 10V 12~18 183 10V 16~20 213 10V 18~24 253 10V 22~28 303 10V 27~33 Note: pulse testing for 380μS.
