ROHM Semiconductor

<p>The ROHM Semiconductor KDZTR3.9B is a single Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 4.1V with a tolerance of ±6%, and a power dissipation rating of 1W. The device is housed in a compact SOD-123F surface-mount package (supplier device package PMDU), suitable for automated assembly.</p><p>&nbsp;</p><p>This Zener diode offers a reverse leakage current of 40 µA at 1V, ensuring low power loss in standby conditions. It operates over a wide temperature range from -55°C to 150°C, making it suitable for demanding environments. The part is RoHS3 compliant and has an MSL of Level 1 (unlimited), facilitating handling and storage.</p>

<p>The KDZVTR5.6B is a Zener diode from ROHM Semiconductor with a nominal Zener voltage of 5.6V and a maximum power dissipation of 1W. It features a reverse leakage current of 20µA at a reverse voltage of 1.5V. The device is designed for surface-mount assembly in a compact SOD-123F case, also known as PMDU (Power Molded Ultra-compact). It can operate at junction temperatures up to 150°C. This Zener diode is suitable for voltage regulation, overvoltage protection, and general-purpose clamping applications in consumer and industrial electronics. The small footprint enables high-density PCB layouts. No additional design parameters such as Zener impedance or tolerance are available in the current data; refer to the manufacturer's datasheet for detailed specifications.</p>
