The MMSD4148T1G is a general-purpose switching diode from On Semiconductor, designed for high-speed switching applications. It offers a continuous reverse voltage rating of 100V and a forward current capability of 200mA. The device features a fast reverse recovery time of 4ns, making it suitable for high-frequency switching circuits.
Key electrical characteristics include a maximum forward voltage of 1000mV at 10mA forward current, and a low reverse leakage current of 25nA at 20V reverse voltage. The diode can handle a forward surge current of 1.0A for less than 1 second and 2.0A for a 1/100 second pulse. The repetitive peak forward current is rated at 0.5A with a 1-second pulse and 66% duty cycle.
The MMSD4148T1G is housed in a SOD-123 surface mount package, which is Pb-Free, Halogen Free/BFR Free, and RoHS compliant. It has a maximum power dissipation of 425mW on an FR-5 board at 25°C ambient temperature, with a derating factor of 3.4mW/°C above 25°C. The junction-to-ambient thermal resistance is 290°C/W. The device operates over a junction temperature range of -55°C to +150°C.
