P-Channel JFET CORPORATION J270 – J271 / SST270 – SST271 DESCRIPTION FEATURES • Surface Mount The J270/SST270 Series is an all-purpose amplifier for designs requiring P-channel operation. These devices feature high gain, low noise and tight VGS(OFF) limits for simple circuit design. They are available in low-cost SOT-23 and TO-92 packages and are fully compatible with automatic insertion techniques.
