TK20A60W5 600V 20A N-Channel MOSFET for PSU Repair
The TK20A60W5 is a 600V 20A N-channel silicon power MOSFET built on the DTMOS (double-diffused MOS) super-junction process. The combination delivers fast reverse-recovery time (110 ns typical) and low drain-source on-resistance (0.15 Ω typical) — the headline traits that translate into high switching efficiency and high power density in switching voltage regulators.
Used in the primary-side or PFC stage of various SMPS designs, including mining PSU rebuilds where a low-RDS(on) 600V MOSFET is required. The super-junction structure also enables efficient power handling under continuous-duty load.
Typical Use in PSU Repair
- Primary-side MOSFET replacement — failed switch in PFC / half-bridge / DC-DC stage.
- Efficiency upgrade — replace older silicon MOSFETs with DTMOS for cooler operation.
- Hard-failure recovery — short-circuit failures during transient events.
- Production refurbishment — bulk MOSFET stock for SMPS rebuild lines.

FAQ — TK20A60W5 MOSFET
Q: DTMOS vs standard super-junction — what's the difference?
A: DTMOS is a refined super-junction process targeting fast trr + low Qg + low RDS(on) simultaneously. Result: a MOSFET friendly to high-frequency switching with manageable conduction losses.
Q: Substitution for older 600V MOSFETs?
A: TK20A60W5 can replace many 600V-class MOSFETs at lower or equal current rating — check Vgs threshold, Qg and package fit before swapping.
