RF PIN diode in a tiny leadless package
The Infineon BAR6302LE6327XTMA1 is a single PIN diode designed for RF switching and attenuation up to several GHz. Its key specs for the RF designer are a low capacitance of 0.3 pF at 5 V and 1 MHz, and a forward resistance of 1 Ohm at 10 mA and 100 MHz — the combination that gives good isolation in the off-state and low insertion loss when forward-biased. Peak reverse voltage is 50 V, and the part handles up to 100 mA continuous current with 250 mW power dissipation. It sits in a SOD-882 package (Infineon calls it PG-TSLP-2-1), a two-lead leadless package roughly the size of a grain of sand.
0.3 pF — what it buys you in the RF path
The 0.3 pF off-capacitance at 5 V reverse bias determines isolation at frequency.

Active and RoHS3 — no lifecycle surprises
The BAR6302LE6327XTMA1 carries an Active lifecycle status and is ROHS3 Compliant. That means no last-time-buy pressure, no PCN for obsolescence on the near horizon. The ROHS3 compliance covers all six original substances plus the four phthalates — no exemption declarations needed for EU market builds.
