SMCJ43A-13-F Transient Voltage Suppressor Diode

The SMCJ43A-13-F from Diodes Incorporated is a robust transient voltage suppressor (TVS) diode designed to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events. This TVS diode is a popular choice for safeguarding voltage-sensitive components which can be affected by these sudden surges.

Engineered in a compact SMC package, the SMCJ43A-13-F offers a 43V standoff voltage, which makes it suitable for a broad range of applications. Its peak pulse power dissipation is rated at 1500W (10/1000μs), providing a high level of protection for electronic circuits from voltage spikes and surges. The device is designed to clamp excess transient voltages and shunt them to the ground, preventing damage to the connected components.

The SMCJ43A-13-F features a unidirectional configuration, which means it offers protection in one direction and is ideal for DC voltage circuits. It has a fast response time, typically responding to over-voltage events in less than 1 picosecond, ensuring that the protected components are not exposed to damaging voltages for any significant period.

Key specifications of the SMCJ43A-13-F include:

• Standoff Voltage: 43V
• Breakdown Voltage Range: 47.8V to 52.8V
• Maximum Clamping Voltage: 69.4V at 21.5A
• Peak Pulse Power Dissipation: 1500W (10/1000μs waveform)
• Maximum Peak Pulse Current: 21.5A
• Response Time: < 1ps from 0V to BV min
• Operating Temperature Range: -55°C to +150°C
• Package: SMC (DO-214AB)

Manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete, logic, analog, and mixed-signal semiconductor markets, the SMCJ43A-13-F is RoHS compliant and adheres to ISO 9001 and ISO 14001 standards. It is an ideal choice for use in sensitive electronics protection in industrial, commercial, and consumer applications where reliability and performance are critical.

Whether you are designing power supplies, communication systems, or looking to enhance the durability of consumer electronics, the SMCJ43A-13-F provides effective and reliable transient voltage suppression to ensure the longevity and stable operation of your electronic devices.
