Vishay 1N5259B-TR Zener Diode is a single element, general purpose zener diode offering a nominal zener voltage of 39 V with a maximum power dissipation of 500 mW. It uses a through hole mount type with a compact 2-pin SOD-27 package suitable for industrial electronic circuitry requiring voltage regulation and protection.
This diode features a tight ±5% voltage tolerance and is designed to operate reliably up to 175°C, making it well suited for use in automotive, industrial, and electronic manufacturing applications. The test current of 3.2mA and maximum zener impedance of 80Ω support stable voltage stabilization under operational conditions.
The maximum reverse leakage current is kept to an ultra-low 100nA, enhancing the diode's efficiency and reducing power loss. It adheres to the AEC-Q101 automotive standard, ensuring compliance with international automotive quality requirements.
Physically, the diode measures 1.7mm in height and 3.9mm in length, allowing it to fit into compact PCB layouts and dense assembly lines. This product is manufactured in China and is supplied new, making it a reliable choice for engineers and technicians designing power management, voltage regulation, or protection circuits.
This diode provides a nominal 39 V zener voltage with ±5% tolerance. It supports a maximum power dissipation of 500 mW for safe operation. The package type is SOD-27, suited for through hole mounting. Maximum operating temperature is rated at 175°C for durability.
The device complies with AEC-Q101 automotive standards. Low maximum reverse leakage current of 100nA enhances efficiency. The compact size facilitates integration into space-constrained assemblies.
This Vishay zener diode is ideal for use in semiconductor, electronic components, automotive electronics, power supplies, industrial manufacturing, and applied electronics projects requiring precise voltage regulation and protection.
