The SMDJ20CA is a 3000W bidirectional TVS diode from Littelfuse, part of the SMDJ series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. This component offers a reverse standoff voltage of 20V and a clamping voltage of 32.4V, with a peak pulse current rating of 92.6A under 10/1000μs waveform.
Key electrical characteristics include an ultra-fast response time of less than 1ps, making it suitable for high-speed data lines. It also features ESD withstand voltage of 30kV (air and contact) per IEC 61000-4-2, and low leakage current of less than 2μA. The device is bidirectional, providing symmetrical protection for AC or dual-polarity circuits.
The SMDJ20CA is housed in a surface mount DO-214AB (SMC) package, which is ideal for automated assembly and space-constrained designs. It supports an operating temperature range of -65°C to 150°C and a storage temperature range of -65°C to 175°C. Thermal resistance is 15°C/W junction-to-lead and 75°C/W junction-to-ambient.
This TVS diode is suitable for general purpose applications including I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. It is RoHS3 compliant, halogen free, and has UL flammability rating V-0.
