Product Description
Littelfuse SMBJ40A is a 1-element, uni-directional transient voltage suppression (TVS) diode designed to protect sensitive electronics from voltage surges and transient events. Rated at 600 W peak pulse power dissipation, it features a compact 2-pin, DO-214 surface mount package that offers excellent board space savings and ease of use.
This diode has a minimum breakdown voltage (Vbr) of 44.4 V and a maximum reverse stand-off voltage (Vwm) of 40 V. It clamps voltage spikes to a maximum of 64.5 V, effectively protecting downstream semiconductor components from damage. The device supports a maximum peak pulse current (Ippm) of 9.3 A with an extremely low maximum reverse leakage current of 1 μA, ensuring minimal leakage in normal operation.
Designed for industrial, electronic, power supply, and communication circuit protection applications, the SMBJ40A operates reliably across a wide temperature range from -65°C to 150°C, making it suitable for harsh environments. Its surface mount package type DO-214 facilitates easy assembly in automated production lines with high reliability.
The diode's single element configuration simplifies circuit design and reduces component count, ideal for transient overvoltage protection in DC circuits. Its robust characteristics make it suitable for power management, consumer electronics, and other industrial equipment requiring transient voltage suppression.
