onsemi SMBJ40CA is a 1-element bi-directional Transient Voltage Suppression (TVS) diode rated for 600 W peak pulse power. It is housed in a compact 2-Pin DO-214 surface mount package, suitable for effective protection of sensitive electronics against voltage spikes and transient surges.
This TVS diode offers a minimum breakdown voltage of 44.4 V and can withstand maximum reverse stand-off voltages up to 40 V. It features a clamping voltage of 64.5 V, ensuring it quickly clamps high voltage surges to safe levels. The device supports a maximum peak pulse current of 9.3 A and tests at 1 mA current, making it ideal for transient suppression in various industrial, automotive, and consumer electronic applications.
Designed for surface mounting, the SMBJ40CA package dimensions measure approximately 4.05 mm in length, 3.95 mm in width, and 2.45 mm in height, facilitating compact PCB layouts. It performs reliably over a wide temperature range from -55°C to 150°C. The device’s glass-passivated junction construction provides enhanced durability and fast response times.
Key features include low incremental surge resistance and a maximum reverse leakage current of 5 μA, reducing power losses and improving efficiency. The product conforms to standard manufacturing practices but carries no specific automotive or other certification. It is suitable for use in industrial power supplies, telecommunications, consumer electronics, and automotive electronic protection circuits.
Single element configuration for bi-directional transient voltage suppression. 600 W peak pulse power rating for high protection level. Surface mount DO-214 package with 2 pins. Breakdown voltage of 44.4 V and stand-off voltage of 40 V.
Clamp voltage of 64.5 V assures safety of sensitive components. Operating temperature from -55°C to 150°C for harsh environments. Fast response and low leakage ensure efficiency and longevity. Glass-passivated junction for reliability.
