LDBL20D-25R ST RF Diode | 4-STSTAMP™ (0.47x0.47) | 20V, 0.5pF

Product Overview

The LDBL20D-25R from STMicroelectronics is a high-performance RF Schottky diode designed for low-level detection and mixing applications up to 12 GHz. Housed in a compact 4-STSTAMP™ package measuring just 0.47x0.47 mm, it offers excellent RF characteristics with low junction capacitance (0.5 pF typical) and low forward voltage (0.35 V at 1 mA). This device is ideal for wireless communication systems, radar, and test equipment where small size and high sensitivity are critical.
