Rohm Semiconductor PTZTE257-5A is a 1W Zener Diode designed for precise voltage regulation. Featuring a Zener Voltage (Vz) of 7.95V with a tight tolerance of ±5.66%, this component is suitable for applications requiring stable reference voltages. Its maximum power dissipation is 1W, and it exhibits a low impedance (Zzt) of 4 Ohms at its rated voltage. Ideal for surface mount applications, the PTZTE257-5A is housed in a DO-214AC, SMA package, commonly known as PMDS. The diode operates efficiently within a temperature range of -55°C to 150°C (TJ) and presents a reverse leakage current of 20 µA at 4V. This component finds utility in automotive, industrial control, and telecommunications sectors where reliable voltage clamping and regulation are critical. Supplied in Tape & Reel (TR) packaging.
