The 1.5SMC33CA-E3/57T is a bidirectional transient voltage suppressor (TVS) diode from the Vishay 1.5SMC series, designed to protect sensitive electronics from voltage transients induced by inductive load switching and lightning. It features a peak pulse power dissipation of 1500W for a 10/1000 µs waveform, with a maximum clamping voltage of 45.7V at a peak pulse current of 32.8A. The device is housed in a surface mount SMC (DO-214AB) package, ideal for automated placement and low-profile applications.
The bidirectional construction (CA suffix) allows the same electrical characteristics to be applied in both directions, making it suitable for protecting AC lines or bidirectional signal lines. The junction operating temperature range is -65°C to 150°C, and the device is RoHS compliant with an MSL level of 1. The glass passivated chip junction ensures reliable performance, and the matte tin plated leads are solderable per J-STD-002.
Typical applications include general-purpose transient protection in consumer, computer, industrial, automotive, and telecommunication equipment. The device is also qualified for automotive use (AEC-Q101) with alternative ordering codes. With its fast response time and low incremental surge resistance, the 1.5SMC33CA-E3/57T provides robust protection for ICs, MOSFETs, and sensor units.
