BMS3003 is listed in the Single FETs, MOSFETs range at ChipApex. The manufacturer field lists onsemi. Its product description is MOSFET P-CH 60V 78A TO220ML. Review the specifications below when checking this part for your BOM.
The BMS3003 is a P-Channel Silicon MOSFET designed as a general-purpose switching device. It features an ON-resistance of 5.0 mΩ (typ.) at VGS=-10V and 6.5 mΩ (typ.) at VGS=-4V. The device supports a drain current of -78 A (DC) and withstands a drain-to-source voltage of -60 V. Key electrical parameters include an input capacitance of 13200 pF, total gate charge of 285 nC, and a forward transfer admittance of 130 S. It operates within a channel temperature range up to 150 °C.
Verify the manufacturer origin, as the component was originally produced by Sanyo Semiconductor Co., Ltd. Confirm package details correspond to TO-220ML(LS). Ensure compliance with standard application guidelines, avoiding use in safety-critical or special applications without prior consultation. Check for any specific ordering suffixes that may indicate updated revisions.
Select this component for applications requiring robust P-Channel switching with high current capacity. Consider the thermal dissipation capabilities when designing for continuous operation at -78 A. Evaluate the gate drive requirements to utilize either the -10V or -4V optimized performance characteristics. Ensure the operating voltage does not exceed the -60 V drain-to-source rating.
This part is a P-Channel Power MOSFET from the Sanyo Semiconductor portfolio, now associated with onsemi following corporate acquisitions. It belongs to the category of general-purpose discrete semiconductors used for load switching and power control in consumer and industrial electronics.
Check for direct equivalents such as the BMS3003-1E. Verify pinout compatibility and electrical parameter overlaps before substitution.
