WMJ53N65F2 - High-Quality 650V N-Channel Diode Junction MOSFET for Power Electronics
Enhance the performance of your power electronics with the WMJ53N65F2, a high-quality 650V N-channel diode junction MOSFET. This MOSFET delivers fast switching capabilities and reliable performance, making it an excellent choice for demanding power applications. With its TO-247 package, it provides a familiar format that is easy to integrate into existing systems.
Upgrade Your Power Electronics with the WMJ53N65F2 MOSFET
The WMJ53N65F2 boasts impressive specifications, including a VDS (drain-source voltage) of 650V, ensuring robust operation in high-voltage environments. With an RDS(on) (on-resistance) of 0.078Ω @VGS=10V (max.), it minimizes power loss and enhances overall efficiency. The ID (continuous drain current) of 50A @TA=25℃ allows for handling significant power loads, while the PD (power dissipation) of 350W @TA=25℃ ensures efficient heat dissipation.

Frequently asked questions
Can I replace any 650V TO-247 MOSFET with the WMJ53N65F2?
Electrically, yes — provided VDS, RDS(on), ID and gate charge are similar or better. Always check pinout, mounting hole position and confirm the gate-drive design can handle the new Qg before swapping.
Why did my replacement FET fail again?
Recurring primary-FET failure points to upstream damage: bulk capacitor with high ESR, broken snubber, damaged PWM controller, weak gate driver or wrong gate resistor. Inspect and replace these before fitting another expensive 650V switch.
Does the WMJ53N65F2 need a fresh thermal pad?
Yes. Replace the silpad or thermal paste under the TO-247 tab whenever the device is removed — a degraded thermal interface accelerates the next failure.
Do you ship in bulk for repair shops?
Yes. Contact us with quantity and target spec; we can source matched batches and offer volume pricing.
