The 15N120 IGBT is a high power and high voltage handling electronic component. This component is most commonly see in induction cook top, electronic welding machines and UPS system. These isolated gate BJT device has high efficiency and high switching speed. This article shares the Pinout, equivalent and specifications of 15N120.
15N120 IGBT Specifications
- Collector-Emitter Voltage is 1200V.
- Collector Current is 15A.
- Saturation Voltage is typically low, around 1.8V to 1.9V
- The package is Often TO-247
15N120 IGBT Pinout Diagram
Pinout configurations
To check the pinout, hold the IGBT numbers facing you and the pins are pointing downward and count the pins from left to right as Gate, Collector and Emitter.
| Pin No. | Pin Name |
|---|---|
| 1 | Gate (G) |
| 2 | Collector (C) |
| 3 | Emitter (E) |
Equivalent and Replacement
Suitable equivalents are FGA15N120, FGA15N120ANTD, IHW15N120R3, GT15N120, NGTB15N120IH, 15N120NDH
How to Test a 15N120 IGBT with a Multimeter
First we need to check the internal short of collector and emitter pin of IGBT. set the multimeter knobs to continuity mode and connect the probes in emitter and collector pins. if no beep or resistance showing means it is not shorted and working good.
Applications
- In induction cooker and micro wave ovens need high voltage and current, so a powerful switching device is needed so the 15N120 can do this.
- In high power inverters the IGBT used for DC to AC conversion.
- In motor driver circuits the speed of motor is controlled by frequency adjustment to the IGBT or MOSFET’s so this powerful IGBT can drive high current motors.
