Overview

Description

The SMAJ24A is a transient voltage suppressor (TVS) diode designed to protect electronic circuits from voltage spikes and surges. It is commonly used in applications where sensitive components need protection from electrostatic discharge (ESD), electrical fast transients (EFT), and other over-voltage conditions.
Key features of the SMAJ24A include:
1. Peak Pulse Power: Capable of handling high power in a short duration, typically rated at 400 watts for an 8/20 μs waveform.
2. Reverse Stand-off Voltage: The diode has a stand-off voltage of 24 volts, meaning it remains inactive under normal operating conditions below this threshold.
3. Response Time: Extremely fast response, usually in the picosecond range, which is essential for effective surge protection.
4. Package Type: Available in the DO-214AC (SMA) package, which is compact and surface-mountable, making it suitable for high-density circuit boards.
The SMAJ24A is widely used in automotive, telecommunications, and industrial applications due to its reliability and efficiency in protecting against transient voltage threats.

Equivalent

The SMAJ24A is a unidirectional TVS (Transient Voltage Suppressor) diode. Its equivalent products include 1.5KE24A, P6KE24A, and SMCJ24A. These components are also designed for overvoltage protection in electronic circuits and share similar electrical characteristics, such as breakdown voltage and power dissipation capabilities. Always verify specific parameters and compatibility for your application when selecting an equivalent.

Features

The SMAJ24A is a Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronics from voltage spikes induced by inductive load switching and lightning. Here are its key features:
1. Breakdown Voltage: Typically 24V.
2. Peak Pulse Power: Rated at 400W with a 10/1000µs waveform, providing robust protection against voltage transients.
3. Response Time: Fast response time, typically less than 1.0 picosecond from 0V to the breakdown voltage.
4. Polarity: Unidirectional, meaning it is designed to protect against voltage spikes in one direction.
5. Package Type: Available in a DO-214AC (SMA) package, which is surface-mountable for ease of use in automated assembly processes.
6. Low Leakage: Exhibits low reverse leakage current, minimizing power consumption when inactive.
7. Operating Temperature: Capable of operation in a wide temperature range, typically -55°C to 150°C.
8. Applications: Commonly used in consumer electronics, telecommunication equipment, and automotive circuits to safeguard components like microcontrollers and ICs from voltage surges.
These features make the SMAJ24A a reliable choice for circuit protection in various applications.

Pinout

The SMAJ24A is a type of transient voltage suppressor (TVS) diode used for protecting sensitive electronics from voltage spikes. It typically comes in a DO-214AC (SMA) package. The pin count for an SMA package is two: an anode and a cathode.
The primary function of the SMAJ24A is to clamp overvoltages to a safe level, thus protecting electronic circuits from the harmful effects of voltage transients such as electrostatic discharge (ESD), electrical fast transients (EFT), and lightning-induced surges. The "24A" in its designation indicates a standoff voltage of 24 volts, which is the maximum voltage the diode can handle under normal operating conditions without conducting.
The SMAJ24A is unidirectional, meaning it is designed to handle voltage spikes in one polarity. It is widely used in applications such as power supplies, telecommunications, and automotive electronics to enhance circuit reliability and longevity.
