Features improves noise immunity and high temperature blocking stability at the expense of increased trigger and holding current. External resistors are optional for nonsensitive SCRs and TRIACs. They should be comparable in size to the internal shorting resistance of the device (20 to 100 ohms) to provide maximum improvement. The internal resistance of the thyristor should be measured with an ohmmeter that does not forward bias a diode junction. 1 MEG 100 K 10K 0.001 0.01 0.1 1 10 100 STATIC  dV  (Vńms) dt dV Figure 6.6.

High Fidelity Switching Audio Amplifiers Using TMOS Power MOSFETs
AN1042/D High Fidelity Switching Audio Amplifiers Using TMOS Power MOSFETs Prepared by: Donald E. Pauly ON Semiconductor Special Consultant http://onsemi.com APPLICATION NOTE With the introduction of complementary bipolar power transistors in the late 1960s, switching amplifiers became theoretically practical. At low frequencies, bipolar transistors have switching efficiencies of 99% and will directly drive a low impedance speaker filter. The requirement for switching frequencies above 100 kHz resulted in excessive losses however. Bipolar drive circuitry was also complex because of its large base current requirement. With the advent of complementary (voltage/current ratings) TMOS power MOSF...

Unique Features of the MCP23X08/17 GPIO Expanders
The I/O port is highly configurable for maximum flexibility. Figure 1 is a simplified block diagram of an I/O port pin. The port can either drive logic levels on the pin, or read logic levels from the pad. The level on the pad can be read at any time, regardless if the pin is configured as an input or an output. The IODIR register controls the direction of the pins (input or output). More specifically, the IODIR registers simply enables/disables the output driver. When the driver is activated (IODIR = 0), the pad is driven to the state in the latch register (OLAT). When deactivated (IODIR = 1), the driver is high impedance. The I/O port has multiple, individual configurations. Each pin can …...

RC Snubber Networks
AN1048/D RC Snubber Networks For Thyristor Power Control and Transient Suppression By George Templeton Thyristor Applications Engineer http://onsemi.com APPLICATION NOTE INTRODUCTION Edited and Updated RC networks are used to control voltage transients that could falsely turn-on a thyristor. These networks are called snubbers. The simple snubber consists of a series resistor and capacitor placed around the thyristor. These components along with the load inductance form a series CRL circuit. Snubber theory follows from the solution of the circuit’s differential equation. Many RC combinations are capable of providing acceptable performance. However, improperly used snubbers can cause unrel...
