Optimal for driving inductive loads. Freewheeling diodes can be reduced!
A Zener diode is connected (built-in) between the collector and base of the transistor with a resistor, protecting the transistor from back electromotive force during motor and solenoid drive operations through active clamp operation. Additionally, because it has a built-in resistor, it allows for direct input from microcontrollers, and its compact surface-mount design contributes to the miniaturization of the set and a significant reduction in the number of components. Furthermore, with a rated current of 1.0A, it is also ideal for use as a driver.

Company information
Isahaya Electronics began production of small signal transistors in 1973 and has evolved its semiconductor technology into design technologies for gate drivers and DC/DC converters. In recent years, the company has also focused on developing high-efficiency, high-power-factor power supply technologies to contribute to carbon neutrality. (Three-phase PFC, 1500V input compatible DC/DC converters, bidirectional converters, etc.) Meanwhile, to meet diverse needs, small signal transistors have also evolved with enhanced functionality and integration, expanding the lineup of high-voltage, high-current transistors, MOSFETs, and analog ICs.
