Product details

70V Schottky for RF detector and mixer front-ends

The 1N5711 is a small-signal Schottky diode built for RF detector, mixer, and clamping applications where low junction capacitance and fast switching matter more than current handling. Its 70V peak reverse voltage and 2pF capacitance at 0V bias make it a common choice for RF probe tips, power detectors, and microwave mixer stages through X-band.

2pF capacitance – the RF enabler

The 2pF capacitance at 0V, 1MHz sets the upper frequency limit for detection and mixing. The 15 mA max current confirms this is a signal diode, not a power rectifier.

DO-35 axial – through-hole legacy

The DO-204AH (DO-35) axial-lead glass package is a through-hole format that predates surface-mount assembly. The axial leads require hand-insertion or selective-solder processes; no pick-and-place tape-and-reel option exists for the DO-35 body.

Sourcing is limited to surplus inventory held by independent distributors.

Frequently asked questions

What is the capacitance of the 1N5711?

The junction capacitance is 2pF at 0V reverse bias, measured at 1MHz. This low capacitance is what makes the 1N5711 suitable for RF detector and mixer circuits through several GHz.
