The 1KSMB27CA is a 1000W bidirectional TVS diode from Littelfuse, part of the 1KSMB series. It is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. The device offers a peak pulse power of 1000W (10/1000μs waveform) and a clamping voltage of 37.5V at a peak pulse current of 26.7A. It has a fast response time of less than 1.0ps from 0V to breakdown voltage, making it suitable for ESD and EFT protection per IEC 61000-4-2 and 4-4 standards.
The diode operates over a junction temperature range of -65°C to 150°C (as per datasheet) and features a low thermal resistance of 20°C/W junction-to-lead and 100°C/W junction-to-ambient. It is packaged in a DO-214AA (SMB) surface mount package, which is optimized for board space and offers a low profile. The device is halogen free, RoHS compliant, and has Pb-free E3 terminal finish.
Typical applications include protection of I/O interfaces, VCC bus, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The 1KSMB27CA is available in tape and reel, cut tape, or Digi-Reel packaging from distributors.
