SMAJ TVS Diode Series is a high-reliability Transient Voltage Suppressor diode designed to protect sensitive electronic circuits from sudden voltage spikes, surges, and transient over-voltage events. These diodes provide fast response and effective clamping performance to prevent damage to ICs, MOSFETs, microcontrollers, and other semiconductor devices.

The SMAJ series is widely used in industrial, power supply, telecom, automotive electronics, LED drivers, and consumer electronic applications where stable and long-term circuit protection is required.

Diode House is one of the most popular stockists and distributors across India, supplying genuine and brand-certified industrial electronic components. We also support export supply to UAE Dubai, Bangladesh, Sri Lanka, and other international markets.
