概述

Description

The 1.5KE400CA is a type of transient voltage suppression diode, commonly used to protect electronic circuits from voltage spikes or transients. It belongs to the 1.5KE series of TVS diodes, which are designed for unidirectional and bidirectional applications. The "400" in its name refers to its breakdown voltage, which is approximately 400 volts, allowing it to clamp over-voltage conditions effectively without damaging sensitive components.
This device has a peak power dissipation capability of 1500 watts (for a duration of 8/20 microseconds), making it suitable for applications in automotive, telecommunications, and industrial electronics where high transient voltages may occur. The 1.5KE400CA is housed in a DO-41 package, ensuring easy integration into circuits. It is crucial for maintaining circuit integrity and reliability by minimizing the risk of damage from electrostatic discharge (ESD) and voltage surges.

Features

The 1.5KE400CA is a bi-directional transient voltage suppression (TVS) diode, designed to protect sensitive electronic components from voltage spikes and transients. Key features include:
1. Peak Pulse Power: Handles a maximum peak pulse power of 1500W (for 10/1000μs waveform).
2. Working Voltage: Provides a standoff voltage (V_R) of 400V.
3. Clamping Voltage: Capable of clamping voltage up to 570V at a peak pulse current of 100A (8/20μs waveform).
4. Low Capacitance: Its design minimizes capacitance, making it suitable for high-speed applications.
5. Package Type: Available in a DO-41 package, ensuring easy integration into circuits.
6. Temperature Range: Operates effectively over a wide temperature range, typically from -55°C to +150°C.
7. Compliance: Meets various industry standards for reliability and performance.
These features make the 1.5KE400CA ideal for protecting circuits in automotive, telecommunications, and industrial applications.
