BLM4953

BL(Shanghai Belling) · MOSFETs · SOP-8

BLM4953 from BL(Shanghai Belling), in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S1 passive Source of P-channel MOSFET 1; the device is rated for VDS = -30V and ID = -5.1A.
2 G1 input Gate of P-channel MOSFET 1; VGS is limited to ±20V, and the device operates with gate voltages as low as 4.5V.
3 S2 passive Source of P-channel MOSFET 2; the device is rated for VDS = -30V and ID = -5.1A.
4 G2 input Gate of P-channel MOSFET 2; VGS is limited to ±20V, and the device operates with gate voltages as low as 4.5V.
5 D2 passive Drain of P-channel MOSFET 2, tied to pin 6; VDS maximum is -30V and continuous ID is -5.1A.
6 D2 passive Drain of P-channel MOSFET 2, tied to pin 5; VDS maximum is -30V and continuous ID is -5.1A.
7 D1 passive Drain of P-channel MOSFET 1, tied to pin 8; VDS maximum is -30V and continuous ID is -5.1A.
8 D1 passive Drain of P-channel MOSFET 1, tied to pin 7; VDS maximum is -30V and continuous ID is -5.1A.
