Zener Diode PATIKIL 20 piece 1W 15V DO-41 Assortment for Labs

Description

Product Overview

The PATIKIL Zener Diode Assortment brings together twenty high‑quality DO‑41 style diodes, each rated at 15 volts and 1 watt of power dissipation. Engineered for precision voltage regulation, these components feature a compact cylindrical body measuring 4 mm in length and 2.4 mm in diameter, allowing seamless integration onto standard printed circuit boards. The diodes are fabricated from silicon material that offers excellent thermal stability and low leakage current, ensuring that the voltage across the device remains constant even when the current varies widely. This stability is essential for protecting sensitive electronic circuits from voltage spikes and for establishing reliable reference voltages in analog and digital applications.

Each diode in the set conforms to the DO‑41 package dimensions (4 mm × 2.4 mm) and includes a total lead length of 60 mm, providing ample flexibility for soldering and wiring in prototype boards or production assemblies. The assortment is packaged in a sturdy anti‑static bag to guard against electrostatic discharge during storage and handling, and the entire lot is shipped in a compact box measuring 3.62 × 2.4 × 0.63 inches, weighing only 0.35 ounces, making it convenient for both hobbyists and professional engineers.

Usage

These 15 V Zener diodes are versatile components suitable for a broad range of applications. In laboratory environments, they serve as reference voltage sources for calibration of measurement equipment, as well as protective elements in power supply circuits where they clamp excess voltage to safe levels. For product development teams, the diodes enable rapid prototyping of voltage‑regulated modules, such as battery chargers, LED drivers, and sensor interface circuits, where precise voltage control is critical for performance and longevity.

Maintenance technicians often rely on Zener diodes to replace failed voltage regulation parts in existing equipment, and the 1 W power rating ensures that the diodes can handle moderate current loads without overheating. The diodes are also ideal for educational settings, allowing students to explore semiconductor behavior, breakdown voltage characteristics, and the practical implementation of voltage regulation in real‑world circuits. Whether you are designing a new device, repairing an existing system, or conducting experiments, the PATIKIL Zener diode set provides a reliable, cost‑effective solution.

FAQ

What is the correct polarity for installing these Zener diodes?

Zener diodes have a marked cathode end, usually indicated by a stripe on the body. The cathode should be connected to the more positive side of the circuit when the diode is used in reverse‑bias mode for voltage regulation. Installing the diode with reversed polarity can prevent it from regulating correctly and may cause damage.

Can these diodes be used in high‑frequency applications?

While the DO‑41 package is primarily designed for low‑to‑moderate frequency circuits, the silicon construction offers reasonable performance up to a few megahertz. For very high‑frequency or RF applications, a diode specifically rated for those frequencies is recommended.

How do I determine the appropriate series resistor value for a Zener regulator circuit?

First, calculate the maximum current the Zener diode will need to maintain its breakdown voltage, then select a resistor that limits the current to a safe level below the diode’s 1 W rating. Use Ohm’s law: R = (Vin – Vz) / Iz, where Vin is the input voltage, Vz is the Zener voltage (15 V), and Iz is the desired Zener current.

Are these diodes suitable for battery‑powered projects?

Yes, the 15 V Zener diodes can be used in battery‑powered designs to create reference voltages or protect against over‑voltage conditions. However, ensure that the battery voltage exceeds the Zener voltage plus the voltage drop across the series resistor to maintain proper regulation.

What warranty or guarantee does PATIKIL provide for this product?

PATIKIL offers a 12‑month limited warranty covering manufacturing defects. If a diode fails due to a defect within this period, you can contact our support team for a replacement or refund, subject to proof of purchase and compliance with warranty terms.
