Product Description
Taiwan Semiconductor SMBJ170A is a single-element, uni-directional transient voltage suppressor designed to protect electronic circuits from voltage spikes and transient surges. This device features a surface mount DO-214AA (SMB) package with 2 pins, providing a compact solution for surge protection in electronic assemblies.
With a peak pulse power dissipation of 600W and a clamping voltage of 275V, it efficiently shunts excessive voltages away from sensitive components. The suppressor has a minimum breakdown voltage (VBR) of 189V and a maximum reverse stand-off voltage (VWM) of 170V, ensuring operation within precise voltage thresholds.
The SMBJ170A can withstand peak pulse currents up to 2.2A and operates reliably within a temperature range of -55°C to 150°C, making it suitable for harsh industrial and automotive environments. Its glass-passivated junction construction offers excellent clamping capability, low incremental surge resistance, and fast response time critical for transient suppression.
This device is designed for surface mounting on PCBs, with dimensions 4.75mm length, 3.95mm width, and 2.45mm height. Its low maximum reverse leakage current of 5μA minimizes power loss during normal operation.
