BAP70-03,115

RF Diode Overview

The NXP BAP70-03 is a planar silicon PIN diode housed in an SOD323 (SC-76) surface-mount package. It functions as a high-voltage, current-controlled RF resistor with low capacitance and very low series inductance. Key electrical parameters include a maximum continuous reverse voltage of 50 V and a forward current rating of 100 mA. At 25 °C, the typical junction-to-solder point thermal resistance is 120 K/W. Diode capacitance ranges from 200 fF to 700 fF depending on reverse bias, while forward resistance varies significantly with current levels.
