The HVM187STL-E is a PIN diode rated for 60V. PIN diodes are used as RF switches, attenuators, and high-frequency variable resistors where low capacitance and low on-resistance at forward bias matter. This one is a through-hole part that will swap into a socket or solder into a board — no hot-air station needed, just a standard iron. The 60V breakdown means it handles transmit/receive switching in lower-power RF front-ends or tuning circuits without breaking down on the peaks.
The ROHS3 compliance covers the latest EU exemption roll-up, so it passes the green checklist for new builds without a waiver.
