ROHM Zener Diode 5.1V 500mW Surface Mount SOD-323HE TFZVTR5.1B

The ROHM TFZVTR5.1B is a precision zener diode designed for voltage regulation in surface mount applications. With a regulated zener voltage of 5.1V, this device offers reliable performance and stability across a wide range of electronic designs, including power management, protection circuits, and reference calibration in industrial, laboratory, and consumer electronics.

Engineered for a maximum power dissipation of 500mW, the TFZVTR5.1B is suitable for circuits requiring robust voltage clamping and regulation. The SOD-323HE surface-mount package provides efficient thermal management and solderability, streamlining assembly into densely populated PCBs.

Only one element is present per chip, simplifying integration and minimizing footprint, which is ideal for single-diode uses in voltage reference or protection roles. With a pin count of 2 and a test current of 20mA, the device is easily interfaced for precise voltage regulation requirements.

The TFZVTR5.1B is optimized for operation up to 150°C maximum, ensuring stability in high-temperature environments. It features a low maximum zener impedance of 20Ω and a very low reverse leakage current of 5μA, supporting reliability in sensitive and precision circuits. The device is non-automotive standard and meets strict manufacturing standards for electronics and semiconductor assembly.

Key applications include industrial controllers, instrumentation, power supplies, consumer electronics, and laboratory equipment. With its compact measurements of 2.7mm length and 0.8mm height, the Zener Diode fits effortlessly in space-optimized layouts.
