Its 20 ns reverse recovery time (trr) makes it suitable for high-speed switching applications where a standard recovery diode is acceptable, such as logic-level clamping, flyback suppression, and signal steering up to several MHz. ## Parametric profile for BOM-fit decisions Forward voltage is 1.2 V maximum at 100 mA, and reverse leakage is 500 nA at 75 V — typical for this JEDEC-registered 1N4148 baseline. Capacitance measures 4 pF at 0 V bias and 1 MHz, low enough for RF coupling and high-speed digital clamping without loading the signal path. ## Active lifecycle and compliance posture RoHS compliant per the manufacturer's declaration, with no exemptions listed; suitable for EU and global markets requiring lead-free assembly. ## Sourcing and supply posture The through-hole DO-35 package is a standard axial-lead format, compatible with existing PCB layouts and hand-assembly or wave-solder processes.","metaTitle":"1N4148-1E3 Microchip Technology DO-35 Switching Diode","metaDescription":"Microchip Technology 1N4148-1E3 standard switching diode, 75V reverse, 200mA forward, 20ns trr, DO-35 axial.
