Product Description

The Vishay 1N4751A-TR Zener Diode is a high-precision, silicon planar component engineered for voltage stabilization and clipping in modern electronic, industrial, and automotive applications. Operating at a nominal 30V Zener voltage with ±5% tolerance, this diode ensures stable voltage regulation, making it the ideal solution for protection and reference circuits in power management, measurement, and control systems.

This device features a single-element configuration designed for through-hole assembly, housed within the industry-standard DO-41 package. Its robust silicon planar construction can withstand up to 1.3W power dissipation, permitting effective thermal management in densely packed circuit boards.

The 1N4751A-TR is optimized for operational reliability with a maximum Zener impedance of 40Ω and test current of 8.5mA, supporting consistent performance under varying load conditions. The device maintains low leakage characteristics, with a maximum reverse leakage current of only 5μA, which helps reduce power losses in low-current designs and critical safety paths.

Designed to operate in demanding environments, this Zener diode supports a wide temperature range up to 175°C. It has successfully met the AEC-Q101 automotive standard, ensuring qualification for automotive and industrial applications where operational stability is critical. Its RoHS compliance guarantees suitability for green manufacturing processes, while its compact 4.1mm x 2.6mm form factor allows for high density, high-miniaturization board layouts.

The two-pin configuration ensures straightforward integration into standard PCB designs, and the diode is widely used in power supply protection, reference regulation, voltage clamping, and waveform shaping in a wide range of industries, such as automotive electronics, power supplies, instrumentation, and industrial process controllers.

For engineers and system designers, the Vishay 1N4751A-TR combines excellent electrical characteristics, rugged construction, and industrial-grade reliability.
