1N5236B 7.5V 500mW Zener Diode DO-35 Pack of 5 – ON Semiconductor

Description

Product Overview

The 1N5236B Zener diode is engineered to deliver a precise 7.5 V breakdown voltage while handling up to 500 mW of power dissipation. Housed in a compact DO‑35 (DO-35) axial leaded package, the component occupies minimal board space, making it ideal for dense circuit layouts. Its construction features a double‑slug, metallurgically bonded design that is hermetically sealed within a glass envelope, providing exceptional stability against temperature variations and mechanical stress. The device is Pb‑free and halide‑free, complying with RoHS directives and ensuring a greener manufacturing footprint. Each pack contains five units, allowing designers to stock essential spare parts for long‑term projects.

Beyond the basic electrical parameters, the diode exhibits a low leakage current of typically 5 µA at reverse bias, and a temperature coefficient of 0.05 %/°C, which guarantees consistent performance across a wide thermal range. The glass encapsulation also offers superior resistance to moisture ingress, reducing the risk of corrosion and extending the operational lifespan in humid environments. With a forward voltage drop of approximately 0.7 V at 5 mA forward current, the part integrates smoothly into biasing networks without imposing excessive voltage loss.

Usage

These Zener diodes are suited for a wide range of industrial and scientific applications where reliable voltage regulation is critical. Typical use cases include power supply regulation, reference voltage sources, over‑voltage protection circuits, and precision biasing in analog front‑ends. The robust glass encapsulation tolerates harsh environments, making the part appropriate for automotive electronics, telecommunications equipment, and instrumentation that operate under fluctuating temperature and humidity conditions. Engineers appreciate the consistent 7.5 V reference, which simplifies design calculations and reduces the need for additional compensation components.

In automotive applications, the diode can be employed to protect sensitive control modules from voltage spikes generated by inductive loads such as motors and solenoids. In telecommunications, it serves as a stable reference for RF front‑end bias networks, ensuring signal integrity across long transmission lines. For laboratory instrumentation, the component provides a dependable voltage reference for precision measurement devices, where even minor deviations can affect accuracy. Its compact size also enables deployment in portable devices where board real‑estate is at a premium.
