PIN diode for RF switching and attenuation
The BAP70AM135 is a PIN diode rated for 50 V reverse voltage and 100 mA forward current, housed in a 6-pin TSSOP package. PIN diodes are the standard choice for RF switch and attenuator circuits where low distortion and fast switching are required — the intrinsic layer gives them a low on-resistance at RF frequencies while maintaining high isolation in the off state.
The 50 V reverse rating sets the maximum RF voltage swing the diode can block without forward-biasing — in a 50-ohm system that corresponds to roughly +44 dBm peak power, so this diode suits moderate-power RF front ends (transmit/receive switches, step attenuators) up to a few hundred milliwatts continuous. The 100 mA forward current rating defines the bias current needed to fully forward-bias the intrinsic region; at 100 mA the series resistance drops to its minimum, giving the lowest insertion loss through the switch path.
For a pick-and-place line this means the parts must be loaded into a tube feeder or a vibratory bowl; the line does not get the reel-indexed placement that tape-and-reel provides. Budget for manual kitting or a feeder changeover if your line is set up for reel-only input.
