The ROHM UDZVTE-1727B is a high-performance 27V single zener diode designed for voltage regulation, transient suppression, and precision voltage reference tasks in surface mount applications. With its SOD-323F package, the device is optimized for automated placement, providing designers with flexibility for component layout and soldering reliability. The diode's maximum power dissipation of 200mW allows it to be employed in protection and regulation circuits that require stable voltage clamping under moderate power conditions.
This zener diode features a typical test current of 5mA, ensuring precise operation at its specified zener voltage. The maximum reverse leakage current is only 100nA, which supports low-loss and high-efficiency applications, while the maximum zener impedance of 150Ω at test current ensures predictable behavior for voltage reference use.
The device is constructed to operate across an extended temperature range from -55°C to 150°C, making it highly suitable for industrial, instrumentation, telecom, consumer electronics, and automotive subsystems where environmental stress is a concern. With a length of 2.7mm and height of 0.9mm, its small, low-profile footprint is ideal for modern dense PCB layouts in power management modules, sensors, LED drivers, and battery-powered systems.
The 2-pin surface mount SOD-323F construction allows for streamlined circuit routing and fast assembly. Its low profile not only saves space but also contributes to thermal performance when correctly placed with appropriate copper layout design.
Industrial applications include signal protection, reference cells in analog circuits, and low-voltage clamping against electrostatic discharge or voltage spikes. Laboratory and research settings will benefit from its stability and specified voltage tolerance for precision measurements.
The ROHM 27V 200mW zener diode is part of the UDZV series, delivering consistent quality and electrical performance where users require robust, reliable voltage regulation solutions. Explore the full range of ROHM semiconductors in the Zener Diode category on EnvMart.
