Its key parametrics — 0.28 pF capacitance at 20 V and 800 mOhm series resistance at 100 mA — give the designer a clear trade-off between off-state isolation and on-state insertion loss. ## Capacitance and resistance: the RF design trade-off At 20 V reverse bias, the junction capacitance is 0.28 pF (measured at 1 MHz). That low value keeps the diode from coupling RF signal across the junction in the off state, which matters for isolation in T/R switches and shunt attenuators. Forward-biased at 100 mA (100 MHz), the series resistance drops to 800 mOhm. This on-state resistance directly sets the insertion loss through the diode; 800 mOhm is typical for a small-signal PIN diode in a 50-ohm system, adding roughly 0.07 dB loss per series element. ## Package footprint and thermal reality The diode comes in a 2-XDFN package (NXP designation DFN1006D-2), a 1.0 mm × 0.6 mm leadless package with two side-wettable terminations. Maximum power dissipation is 135 mW, so the thermal path relies on the PCB copper pad under the part — no exposed pad, so the solder fillet on the two terminals is the only heat sink. ## Temperature range and voltage ceiling Junction temperature range spans -65°C to 150°C, covering military and industrial environments. Peak reverse voltage is 50 V, which sets the RF voltage swing limit — for a 50-ohm system, that translates to roughly +34 dBm peak RF power before the diode self-biases into conduction.","metaTitle":"BAP55LX,315 PIN Diode, 50V, 100mA, 0.28pF, DFN1006D-2","metaDescription":"NXP BAP55LX,315 PIN diode: 50V peak reverse, 100mA max, 0.28pF capacitance, 800mOhm resistance.
