Safe Operating Area Calculators
SOA Calculator
The Safe Operating Area Calculators (SOA Calculators) - SOA Calculator for Laser Diode Drivers or the SOA Calculator for Temperature Controllers - are used to determine how much power will be internally dissipated in a product under varied operating conditions. Using your design's input voltage, load size, ambient temperature, etc., the calculator will help you design a thermally robust and reliable system. These tools will allow you to draw the SOA curve for a Wavelength Electronics product and, optionally, to also draw a load line for your specific application to easily design your application to fall within the safe operating area. For a product that combines both laser diode driver and temperature controller, use both.

The WTC3243 Circuit Calculator automatically calculates the gain resistor values based on your thermoelectric or resistive heater currents, the PI loop configuration based on your load type, and sensor gain and bias current to optimize your sensor's responsivity. WTC3243 Details

The WLD3343 Circuit Calculator automatically calculates the limit resistor, PD sense resistor, and LD sense resistor values based on your laser diode current limit and operating mode. WLD3343 Details
