The 6N137SDM from Everlight is a high-speed 10Mbps optocoupler with logic gate output and 3750Vrms isolation in a DIP-8 SMD package for digital signal isolation.
The 6N137SDM is a high-speed optocoupler from Vishay in DIP-8 (SMD variant), providing 10Mbps data rate with 5000Vrms isolation. The device consists of an AlGaAs LED on the input side and an integrated photodetector + amplifier + output driver on the output side. When the LED is forward-biased (IF = 5-15mA), the photodiode receives the light and generates a small photocurrent (approximately 50uA). This photocurrent is amplified by the internal transimpedance amplifier and drives the open-collector output transistor LOW. When the LED is off, the output is HIGH (pulled up by an external resistor). The key to the 10Mbps speed is the photodiode detector (vs. phototransistor used in slow optocouplers): photodiodes have nanosecond response times because they generate current directly from photon absorption, while phototransistors require base charge accumulation and have microsecond response times. The internal amplifier compensates for the low photodiode current, driving the output with sufficient fanout. The propagation delay is 45ns typical (75ns maximum), and the pulse width distortion is 5ns. The open-collector output can sink 13mA. The CTR (Current Transfer Ratio) is not applicable in the traditional sense because the output is logic-level; instead, the device specifies IF(threshold) = 5mA maximum (the minimum LED current to guarantee output switching). The VE (output enable) pin allows tri-stating the output for bus applications. The 5000Vrms isolation provides safety isolation between the driving and receiving circuits. The -SDM suffix specifies DIP-8 SMD (gull-wing leads). Applications include: isolated UART/SPI communication, SMPS feedback loops, and industrial data links.
