在串联型晶体管稳压电路中，集电极电阻有内部电源和外部电源两种供电方式。

There are two kinds of supply modes of collecting electrode resistance (inner and outer) in the voltage-steadied circuit in which series connection transistor is used.

为了减小器件的接触电阻和电流的非均匀性，使用了独特形状的集电极，总的电流密度也因此提高。

A special shape of collector is designed in order to reduce contact resistance and non-uniformity of the current; as a result the total current density in the device is increased.

当放置在横向器件的漏极或垂直器件的集电极中时，多晶填充的沟槽有效地放大了漏极或集电极区域，从而降低了导通电阻。

When placed in the drain of a lateral device or in the collector of a vertical device, the poly-filled trench effectively enlarges the drain or collector region, thereby lowering the ON-resistance.
