The MMBD1504A_D87Z is a small signal diode manufactured by onsemi, housed in an SOT-23 (TO-236) surface-mount package. It features a maximum repetitive reverse voltage of 200 V and supports an average rectified forward current of 200 mA. The device exhibits a non-repetitive peak forward surge current capability of 2.0 A at a pulse width of 1.0 ms. Electrical characteristics include a maximum forward voltage of 1.10 V at 200 mA and a total capacitance of 4.0 pF at 0 V reverse bias and 1.0 MHz frequency. The component operates within a junction temperature range of -55 °C to +150 °C.
Verify the specific ordering suffix D87Z against official documentation to confirm tape and reel specifications and shipping quantities. Confirm that the part status aligns with current manufacturing availability as product lifecycles may change. Ensure compatibility with automated placement equipment regarding the SOT-23 package dimensions and marking orientation before finalizing procurement orders.
Select this component when a dual common cathode arrangement is required within a compact SOT-23 footprint. The 200 V reverse voltage rating provides adequate headroom for standard low-voltage logic and power rails. Consider the thermal resistance and power dissipation limits if operating near maximum current ratings or in enclosed environments requiring derating.
This device belongs to the MMBD150x series of small signal diodes from onsemi. The series includes variants such as MMBD1501A, MMBD1503A, and MMBD1505A, which share similar electrical characteristics but differ in specific device markings and minor parametric tolerances. All members utilize the same SOT-23 case style and are designed for high-speed switching tasks.
NSVMMBD1504ALT1G is a documented alternative within the same family offering automotive qualification.
