With a series resistance of 1 Ω at 20 mA forward current and 100 MHz, it presents a low insertion loss path when forward-biased, making it suitable for SPDT or shunt switch configurations up through low-GHz bands. Capacitance is held to 0.35 pF at 50 V reverse bias and 1 MHz — this low off-state capacitance maintains isolation at the switch port by limiting signal feedthrough across the junction. ## 300 V peak reverse — what it means for the bias network Rated for 300 V peak reverse voltage, the GMP4232-GM1 handles the voltage swing in high-power RF paths or bias-T networks without breakdown — the I-region width is sized for the full 300 V standoff. The -55°C to +125°C operating range covers military temperature-grade environments, so the diode's low-capacitance and low-resistance characteristics are stable across the full thermal profile of an avionics or base-station RF front-end. Packaged in the standard 0805 footprint, it mates directly with coplanar waveguide or microstrip transmission lines on an RF PCB — no extra tuning pads needed for the 2012 Metric body. ## Active lifecycle and compliance posture ROHS3 compliant and supplied in bulk packaging, the part is ready for lead-free reflow assembly without additional process qualification. The GIGAMITE® series is Microchip's established PIN diode portfolio for RF and microwave applications; the GMP4232-GM1 sits as the 0805, 300 V variant in that family.","metaTitle":"Microchip GMP4232-GM1 PIN Diode, 300V, 0805","metaDescription":"Microchip GMP4232-GM1 GIGAMITE® PIN diode, 300V peak reverse, 1Ω @ 20mA.
