The LL4148 is a silicon epitaxial planar diode designed for high-speed switching in small-signal circuits. It features a low forward voltage drop of approximately 0.72V at 10mA and a peak reverse voltage rating of 75V. The device is packaged in a DO-35 glass case, suitable for through-hole mounting on printed circuit boards.
This diode is manufactured using epitaxial silicon technology to ensure fast recovery time and low leakage current. Typical reverse recovery time is under 4ns, making it suitable for frequencies up to 100MHz. The component is not rated for high current applications; its maximum average forward current is 200mA. It is commonly used in signal clamping, rectification, and protection circuits.
Engineers in telecommunications, consumer electronics, and industrial control systems use the LL4148 for transient suppression and signal conditioning. It is often found in data line protection, RF detectors, and logic level shifting circuits. The diode is supplied in bulk tape-and-reel or loose packaging. Minimum order quantities and lead times are confirmed directly with the supplier.

Before ordering, request a sample batch and verify key parameters: reverse recovery time, forward voltage at operating current, and leakage at rated voltage. Use a curve tracer if possible. Confirm the supplier’s packaging method - glass diodes are fragile and require anti-static packaging. Do not accept loose diodes without protective tubes.
Confirm Incoterms - typically FOB Hong Kong or CIF destination - and whether the supplier handles export customs clearance. Lead time is not stated but typically ranges from 7 to 14 days for standard orders. Payment terms are usually 30% advance, 70% against shipping documents. Ask for a commercial invoice with HS code 8541.10.00.
Upon delivery, inspect for physical damage and verify batch codes against the packing list. Test a sample of diodes using a diode tester to confirm forward voltage and reverse leakage. Retain packaging and test records for 12 months. Request a certificate of conformity and test data for each batch, even if not required by regulation.
