I have synthesized the market insights and identified key suppliers for the 2SD400 (D400) transistor.

Market Trends & Technical Insights

The 2SD400 is an NPN epitaxial planar silicon transistor primarily used for low-frequency power amplification and general-purpose switching Radwell.

  • Market Status: It is largely considered a legacy or surplus component (originally by Sanyo), but remains widely available for maintenance and small-scale production RadwellDatasheet4U. The broader power transistor market is growing at a CAGR of ~5.86% through 2026, driven by demand in consumer electronics and industrial automation MordorintelligenceSnsinsider.
  • Key Specs: It features a collector current ($I_C$) of 1.0A, a collector-emitter voltage ($V_{CEO}$) of 25V, and a transition frequency ($f_T$) of 180 MHz Radwell.
  • Pricing: Retail prices range from $0.14 to $1.75 depending on quantity and condition (New, Surplus, or Refurbished) RadwellDatasheet4UAbra-Electronics.

Supplier Overview

I have identified several verified suppliers in China, primarily located in Shenzhen (Guangdong), offering wholesale quantities and distribution services. These suppliers typically provide a wide range of active components and inspection services for international buyers.

The detailed list of suppliers and the market analysis results are available in the files below.

Here are the insights and suppliers for the D400 transistor. You can explore further with:
