Vishay PLZ18B-HG3_A/H is a precision Zener diode designed to provide 17.7 V stable voltage regulation with a maximum power dissipation of 500 mW. Featuring a single-diode configuration, it comes in a compact surface mount DO-219AC (MicroSMF) package optimized for modern compact electronics and PCB designs.
This diode is engineered for industrial and automotive use, meeting stringent standards such as IEC 61000-4-2 for electrostatic discharge protection and AEC-Q101 automotive qualification. It exhibits excellent electrical stability with a low leakage current of 200 nA maximum, making it suitable for sensitive applications requiring consistent voltage reference.
The device operates reliably in harsh temperature environments ranging from -55°C to +150°C and supports wave and reflow soldering processes withstanding high temperatures of up to 260°C at the terminals.
Its characteristics include a test current of 10 mA and a maximum Zener impedance of 23 ohms, ensuring precision voltage clamping. The ultra-small form factor with 2.5 mm length and 0.6 mm height enables it to be used in dense assemblies for telecommunications, power supplies, automotive electronics, instrumentation, and industrial equipment.
Nominal Zener voltage of 17.7 V with general-purpose application. Maximum power dissipation rating of 500 mW for compact power handling. 2-pin surface mount package DO-219AC (MicroSMF) for low profile mounting. Low leakage current and high stability enhance device reliability.
Wide operating temperature range supports demanding environmental conditions. Complies with IEC and RoHS standards for quality and environmental safety. Automotive quality verified under AEC-Q101 standard. Supports high temperature soldering processes up to 260°C.
The Vishay PLZ series offers robust performance in electronic circuit protection, voltage stabilization, and reference voltage functions. Its reliability and compact size make it an ideal choice for designers working in industrial automation, automotive electronics, communication devices, and power management solutions.
