The ZMM55-C4V7_R1_10001 is a RoHS compliant Zener diode manufactured by Panjit. It is a three-terminal, low-leakage, semiconductor device designed to regulate voltages at a fixed point. Its nominal breakdown voltage is 5.5 Volts. It is a low-voltage, high-current component with an operating temperature range of -55°C to +150°C. This part is RoHS compliant, meaning it restricts the use of hazardous substances in the production process, making it a more environmentally friendly choice. The LL34 version is designed to provide a flat capacitance-voltage characteristic over a wide frequency range, making it ideal for bypass, voltage referencing, and surge protection applications.
