NTE123 NPN silicon transistors. The NTE123 is a popular NPN for fuzz pedals and other effects. This transistor is in a TO-5 package. The NTE123 was used in the Texas Square Face made by Cesar Diaz, the famous amp tech who worked with Stevie Ray Vaughan and others. Early in his career, SRV had a broken Fuzz Face pedal and took it to Cesar Diaz to have him fix it. Diaz fixed and modified the pedal and this became the foundation of his famous version which he named the Texas Square Face. The Diaz pedals often came socketed and included a set of NTE123 along with the standard pair of P-QNTE103 to experiment with the different sounds of the transistors.

Alternistors are specifically designed for applications which are required to switch highly inductive loads. To accomplish this, a special chip has been designed which effectively offers the same performance as two thyristors (SCRs) wired inverse parallel (back to back); hence the alternistor has better turn-off behavior than a standard triac.

The AS194H is a junction isolated ultra well-matched monolithic NPN transistor pair with an order of magnitude improvement in matching over conventional transistor pairs. Electrical characteristics of these devices such as drift versus initial offset voltage, noise, and the exponential relationship of base-emitter voltage to collector current closely approach those of a theoretical transistor. Extrinsic base and emitter resistances are very low, giving very low noise and operating over a wide current range. To guarantee long term stability of matching parameters, internal clamp diodes have been added across the emitter-base junction of each transistor. These prevent degradation due to reverse biased emitter current, the most common cause of field failures in matched devices.
