The 20 ns reverse recovery time (trr) means it can switch at moderate frequencies without excessive stored-charge tail — suitable for flyback snubbing, high-speed logic protection, and signal demodulation up to the low-MHz range. ## DO-35 axial package — through-hole integration Housed in a DO-204AH (DO-35) axial-leaded glass package, the 1N4148-1/TR mounts through-hole with standard 0.100-inch lead spacing — the glass body provides hermetic sealing, making it more robust against moisture ingress than molded epoxy in humid environments. Supplied on Tape & Reel (TR) for automated axial-lead insertion machines, the taped format feeds sequentially into high-throughput assembly lines without manual handling. ## Junction temperature range — military-grade extremes Capacitance is 4 pF at 0 V reverse bias and 1 MHz — this low junction capacitance preserves signal edge rates in high-speed digital lines and keeps the diode from loading RF or fast-switching nodes.","metaTitle":"Microchip 1N4148-1/TR DO-35 Signal Diode, 200 mA, 75 V","metaDescription":"Active-production 1N4148-1/TR from Microchip Technology.
