The MMBD4148SE is a small signal diode array from On Semiconductor, consisting of two diodes in a series connection configuration. It is designed for general purpose switching applications and is rated for a maximum repetitive reverse voltage of 100V and an average rectified forward current of 200mA.
Key electrical characteristics include a maximum forward voltage of 1V at 10mA, a fast reverse recovery time of 4ns (tested at IF=10mA, VR=6V, IRR=1mA, RL=100Ω), and low reverse leakage currents of 25nA at 20V and 5nA at 75V. The device also features a low total capacitance of 4pF at 0V, making it suitable for high-speed switching circuits.
The diode array is housed in a surface-mount SOT-23-3 package (also known as TO-236-3 or SC-59), which is lead-free and RoHS compliant. It has a maximum power dissipation of 350mW at 25°C ambient and a thermal resistance of 357°C/W junction-to-ambient.
With its small footprint and enhanced performance, the MMBD4148SE is ideal for space-constrained designs requiring fast switching and low leakage. It operates over a junction temperature range of -55°C to +150°C.
