IRFR9214TRPBF-VB Product details
Back to previous pageProduct introduction：
The IRFR9214TRPBF‑VB is a single P‑channel power MOSFET manufactured using Trench technology, housed in a TO‑252 (DPAK) surface‑mount package. It features a –200V drain‑source breakdown voltage, a typical on‑resistance of 2000mΩ at VGS = 10V, and a continuous drain current of –3.6A. The combination of high voltage capability and the inherent convenience of P‑channel high‑side driving makes it an ideal choice for high‑side switches or primary‑side switching in applications such as high‑voltage auxiliary power supplies, battery pack protection, LED lighting drivers, and industrial controls. The TO‑252 package offers good thermal performance and compatibility with automated assembly, suitable for medium‑density PCB designs.

Domain and module applications：
Application fields and module examples:
1. Battery Management Systems (BMS) & Charging Protection
Typical Modules: Lithium‑ion battery protection boards for e‑bikes/power tools, charge/discharge management modules for portable power stations, battery polarity protection circuits.
–200V VDS rating: Perfectly suited for 48V~72V lithium battery packs (fully charged voltage up to 54V~84V), providing ample margin against over‑voltage spikes from charging or motor back‑EMF.
P‑channel high‑side switch: Placed directly on the positive rail, eliminating bootstrap circuits or isolated supplies; the MCU can directly control the charge/discharge path, simplifying protection board design.
Logic‑level compatibility: Turned on at VGS = 4.5V, compatible with 3.3V/5V MCUs, allowing direct drive from the BMS controller.
3.6A current capability: Adequate for charge/discharge currents of small to medium‑capacity battery packs (e.g., 2~3A charging, 3A continuous discharge).
2. Industrial Control & PLC Output Driving
Typical Modules: PLC digital output modules, solenoid/relay drivers, industrial sensor interface polarity protection and surge suppression circuits.
3. Auxiliary Power Supplies & LED Lighting Drivers
Typical Modules: 48V‑input flyback auxiliary power supplies (generating 5V/12V/24V), PWM dimming and main switching modules for medium‑power LED constant‑current drivers (street lights, industrial luminaires).
