The SMA4F24A is a unidirectional Transil TVS diode from STMicroelectronics, part of the SMA4F series. It is designed to protect sensitive electronic circuits from transient overvoltages caused by ESD, lightning, and other surge events. The device offers a peak pulse power dissipation of 400W under the 10/1000µs waveform and 2.5kW under the 8/20µs waveform, ensuring robust protection in a compact surface-mount package.
Key electrical characteristics include a stand-off voltage of 24V, a breakdown voltage range of 26.7V to 29.6V at 1mA, and a maximum clamping voltage of 50V at 10.3A peak pulse current. The diode features very low leakage current of 0.2µA at 25°C and 1µA at 85°C, making it suitable for high-reliability applications. It operates over a junction temperature range of -55°C to 175°C.
The SMA4F24A is housed in a DO-221AC (SMA Flat Leads) package with a supplier device package of SMAflat, and is surface-mountable. It is RoHS compliant and meets UL94 V0 flammability rating, as well as J-STD-020 MSL Level 1 requirements. The planar technology ensures low leakage and high junction temperature capability for long-term reliability.
