Active clamp type transistor

Active clamp type transistor

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.

High voltage resistance VCEO=400V PNP transistor

High voltage resistance VCEO=400V PNP transistor

Our top-class high-voltage products also feature high surge tolerance.

This is a lead-type PNP transistor with a maximum rating of VCEO=400V and IC=200mA. This maximum rating of VCEO is among the top class in our company, and it has higher current capability and surge tolerance compared to products in the same voltage class. In particular, the surge tolerance can withstand surge voltages more than four times that of the maximum in the same voltage class at the weakest terminal.

LED driver IC with built-in open short detection function 'RT8H174E'

LED driver IC with built-in open short detection function 'RT8H174E'

LED driver with adjustable light output now features additional protection functions, including open and short circuit detection!

This product enables dimming by adjusting the duty cycle of the rectangular wave input to the dimming terminal (DIM) and allows for free setting of the LED current through an external electrical setting resistor. By adjusting the off time with an external resistor and capacitor connected to the CT terminal, energy can be recovered through an externally connected inductor, thereby saving power consumption. As a safety feature, it is equipped with a function that detects when the LED connection is open or shorted to the power supply and outputs an abnormal signal. Additionally, it has a UVLO function to prevent malfunction below 4V and also includes an overheating protection circuit.

MOSFET with built-in Zener diode (for driving varistor-integrated relays)

MOSFET with built-in Zener diode (for driving varistor-integrated relays)

Optimal for driving high inductance relays! Built-in Zener MOSFET has further evolved.

To support relay drive with high inductance that incorporates a barista, we have significantly enhanced the area and voltage resistance of the Zener diode section of the Zener-integrated MOSFET. This has achieved excellent breakdown tolerance, allowing it to withstand transient high voltages. It can be used with greater confidence in high-load applications where reliability is required.
