Microchip Technology SMBJ4746-TR13 is an 18V ±10% surface mount Zener diode designed for voltage regulation and transient voltage suppression applications. This component offers a maximum power dissipation of 2W and features a DO-214AA (SMBJ) package for efficient thermal management. Key specifications include a reverse leakage current of 5 µA at 13.7V and a maximum Zener impedance (Zzt) of 20 Ohms. The diode exhibits a forward voltage (Vf) of 1.2V at 200 mA. Operating across a temperature range of -65°C to 150°C, this device is suitable for use in automotive, industrial control, and telecommunications equipment where robust voltage clamping and regulation are critical. The SMBJ4746-TR13 is supplied on tape and reel (TR13) for automated assembly processes.
