Taiwan Semiconductor SMBJ45CA is a 1-element bi-directional Transient Voltage Suppressor (TVS) diode designed for protecting sensitive electronic circuits from voltage surges. It is housed in a surface mount DO-214 package optimized for insertion into compact printed circuit boards.
This diode provides a peak pulse power dissipation of 600 Watts, making it suitable for high-energy transient events. The device features a minimum breakdown voltage of 50V and a maximum reverse stand-off voltage of 45V, addressing a range of voltage protection needs in power and signal lines.
The clamping voltage at 72.7V ensures rapid suppression of voltage spikes, preventing damage to downstream components. Its bi-directional configuration allows it to protect circuits subject to voltage transients in both polarity directions.
With operational temperature limits from -55°C up to 150°C, the SMBJ45CA can reliably operate in a variety of harsh environments including industrial, manufacturing, automotive, telecommunications, and consumer electronics applications.
The device's low incremental surge resistance and ultra-fast response time enhance its effectiveness in transient suppression, thereby increasing overall system reliability. Single-element diode designed for bi-directional transient voltage protection.
600W peak pulse power dissipation ensures circuit safeguarding. DO-214 surface mount package for efficient PCB integration. Wide operating temperature range from -55°C to 150°C. Low incremental surge resistance and fast response time.
2-pin configuration for flexible mounting options. Ideal for protection in industrial, automotive, and electronics systems. Package includes one SMBJ45CA TVS Diode in DO-214 casing. Explore more semiconductor and protection components within the Electronics & Electricals category at EnvMart.
