The SMBJ12CA-TR is a 12V unidirectional transient voltage suppressor diode from STMicroelectronics. This device is designed to protect vulnerable components from sudden surges in voltage and is often used in automotive applications such as reverse-battery protection and overvoltage protection against ESD. The SMBJ12CA-TR can handle up to 600W peak pulse power and features low clamping voltage and low capacitance. It is available in a SMB (DO-214AC) package with a 90° bend.
