Market Trends & Technical Insights for K8A50D Equivalents

The K8A50D (TK8A50D) is a widely utilized N-channel MOSFET characterized by a 500V drain-source voltage and an 8A continuous drain current, primarily used in high-efficiency power switching and switching regulator applications Semicon-StorageAlldatasheet. The global power MOSFET market is experiencing significant growth, projected to reach approximately $26 billion by 2026, driven by the transition to greener energy and increased demand for power electronics CoherentmarketinsightsYolegroup.

Key Technical Specifications:

  • Package: TO-220SIS (Isolated) — *Note: When using non-isolated equivalents like standard TO-220, insulation mica is required* Semicon-Storage.
  • Low On-Resistance ($R_{DS(on)}$): Typically 0.7 $\Omega$ @ 10V Semicon-StorageAlldatasheet.
  • High Speed: Low gate charge ($Q_g$) of 16 nC allows for fast switching Semicon-Storage.

Recommended Equivalents:

  • Primary Options: 2SK4013 (identical 500V/8A specs) and TK8A50DA (Toshiba's direct variant) Semicon-Storage.
  • Alternative Cross-References: FQPF8N50C (Fairchild/ON Semi), STP8NM50FP (STMicro), and IRFBC40FP (Higher voltage at 600V) Semicon-Storage.

Supplier Analysis

The market currently shows healthy availability on B2B platforms like Alibaba, with unit prices typically ranging from $0.02 to $0.15 depending on volume Alibaba. I have identified several verified suppliers specializing in these components:

  • Shenzhen Winsome Electronic Technology Co., Ltd.: A 16-year verified distributor with revenue between $10M–$50M, holding significant inventory for fast delivery AlibabaAlibaba.
  • Shenzhen Dahongxing Electronics Co., Ltd.: A verified manufacturer and trader with strong OEM/ODM capabilities and CE/RoHS certifications AlibabaAlibaba.

Detailed lists of suppliers for the K8A50D and its common equivalents are provided in the files below for your review.
