Radio Company.The LM5Z30VT1G is a SOD-523 RoHS-compliant, Zener diode manufactured by Leshan Radio Company. It is a low barrier, 5.1V voltage regulating diode that has an operating temperature range of -55°C to +125°C and a maximum power dissipation of 200mW. It is a small and low-cost component housed in a SOD-523 package, which is particularly suitable for surface mount designs, and features a maximum reverse current of 10uA with a zener voltage tolerance of +5%/-20%. It is ideal for applications such as overvoltage clamping, voltage regulation, and bias regulation in switching power supplies, portable electronics, and smoke detectors.
