The onsemi MMBD1505A is a small signal diode housed in an SOT-23 (TO-236) surface-mount package. It features a maximum repetitive reverse voltage of 200 V and an average rectified forward current rating of 200 mA. The device supports a non-repetitive peak forward surge current of up to 2.0 A for short pulses. Electrical characteristics include a maximum forward voltage of 1.15 V at 300 mA and a total capacitance of 4.0 pF at 0 V reverse bias. Operating junction temperatures range from -55 °C to +150 °C.
Verify the specific ordering suffix against the manufacturer's official documentation, as variations exist for automotive qualification or bulk tape-and-reel quantities. Confirm that the component meets the required environmental compliance standards for the target deployment region before finalizing procurement orders.
Select this component when a 200 V reverse voltage rating and 200 mA continuous forward current are required within a compact SOT-23 footprint. Ensure the application operates within the specified thermal limits and does not exceed the non-repetitive surge current ratings during transient events.
This part belongs to the MMBD150xA series of small signal diodes manufactured by onsemi. The series includes variants such as the MMBD1501A, MMBD1503A, and MMBD1504A, which share identical electrical parameters but differ in internal marking codes for identification purposes.
