This listing is four pieces of genuine Toshiba audio power MOSFET 2SK1529/2SJ200.
Toshiba power mosfets are superior to IR/Vishay counterparts in terms of 1. linearity for lower drain current operation, 2. Vgs variation against working temperature.
The 2 pieces of N-channel and 2 pieces of P-channel are tightly Vgs matched respectively to a variance of +/-15mV.
The matching was done at a drain current of 1A to ensure the transistors are well matched for either class AB or class A amplifiers.
