Bourns SMCJ12A Unidirectional TVS Diode 12V SMC Package

The Bourns SMCJ12A Unidirectional TVS Diode 12V is a surface-mount transient voltage suppression diode designed to protect sensitive electronic components from damaging voltage spikes. With a 12 V stand-off voltage and a 1500 W peak pulse power rating, it clamps hazardous over-voltages to a safe level.

Overview

Transient voltages can originate from sources including lightning strikes, the switching of inductive loads, and electrostatic discharge (ESD). This unidirectional diode offers a fast response time of less than 1 ns, providing a first line of defence against these events. Housed in a compact DO-214AB (SMC) package, it is suited to demanding environments where circuit integrity is important.

Key Features

• 1500 W peak pulse power dissipation (10/1000 μs waveform)
• 12 V stand-off voltage (V_RWM)
• 13.3 V minimum breakdown voltage (V_BR)
• Clamping voltage of approximately 19.9 V at 31.4 A
• Peak pulse current of approximately 31.4 A
• Response time of less than 1 ns
• Surface-mount DO-214AB (SMC) package with 2 pins
• Operating temperature range of -55°C to +150°C
• Dimensions (L x W x H): 43 mm x 33 mm x 15 mm
• Part of the SMCJ Series

Applications

The diode is primarily used to protect DC power supply lines from external and internal transients. It is used in automotive electronics to safeguard control units and infotainment systems, in industrial control systems and programmable logic controllers, and in communication equipment such as routers and network switches.
