TLP183GB(GB-TPL.E Обзор
A phototransistor optocoupler is a galvanic isolation device that transfers an electrical signal between two circuits using light, blocking high voltages and transient surges while transmitting the analog or digital signal at the speed of the photodetector. Within the broader component taxonomy, the TLP183 belongs to optoisolators > optocouplers > solid-state relays > isolators > discrete semiconductors, with the phototransistor output placing it in the same family as the Toshiba TLP181, TLP185 and TLP184 series.
Key features include 3750 Vrms minimum isolation voltage, 50 mA maximum forward current, 80 V collector-emitter breakdown voltage, 50 mA collector current, and an operating temperature range of -55C to +110C. The GB CTR rank provides 100% to 300% typical transfer ratio at IF=5 mA and VCE=5 V, which is well suited to digital signal isolation in PLCs and communication interfaces. A GaAs infrared LED emitter delivers fast switching with rise/fall times measured in microseconds.
The TLP183 employs a high-isolation optically-coupled architecture: the input-side GaAs LED converts the input current into modulated infrared light that crosses an internal transparent isolation barrier, after which a silicon phototransistor converts the light back into a current at the output side. The result is complete electrical isolation between input and output while preserving the timing and amplitude characteristics of the original signal.
Typical applications include PLC digital input/output isolation, communication interface isolation (RS-232, RS-485 line-side isolation), power supply feedback loops, and AC mains detection circuits where 3750 Vrms isolation is required by safety standards. The wide -55C to +110C temperature range also supports industrial and consumer-grade equipment.
When designing with the TLP183, ensure that the bias resistor on the LED side limits the forward current to within 50 mA DC, and that the collector pull-up resistor is sized according to the desired switching speed and the chosen CTR rank. Proper creepage and clearance around the SO6 body must be maintained to preserve the 3750 Vrms isolation rating in end-equipment safety certification.

Заметки по проектированию
Do not exceed the 50 mA maximum forward current on the LED input. A typical bias design uses IF between 5 mA and 20 mA - below the absolute maximum but high enough to push the phototransistor deep into saturation. Also ensure that the collector-emitter voltage never exceeds 80 V; for switching inductive loads, add a flyback diode across the collector-emitter.
Maintain minimum 8 mm creepage and clearance on the PCB around the SO6 body to preserve the 3750 Vrms isolation rating. Do not route any copper traces or vias under the optocoupler body that could compromise the isolation barrier. Place the bias resistor and pull-up resistor close to the LED and collector pins respectively, with separate ground returns for primary and secondary sides connected only at one point.
The TLP183(GB-TPL,E operates over -55C to +110C. At maximum forward current (50 mA) and maximum collector current (50 mA), the SO6 package dissipates roughly 100 mW. Estimated: with theta_JA around 130 C/W for the SO6 package on a 1 oz copper 2-layer board, the junction temperature rise is approximately 13C above ambient, well within the 110C limit.
