TLP183(GB-TPL,E Descripción general
An optocoupler (also called an optoisolator or photocoupler) is a semiconductor device that transmits electrical signals between two isolated circuits using a short optical transmission path. The phototransistor-output topology - the dominant sub-type of optocoupler - uses a silicon phototransistor as the receiving element, offering higher load-current handling than logic-output counterparts (e.g. TLP2361) and supporting AC-coupled or DC-coupled analog signal isolation. Within the broader isolation taxonomy (optical isolation -> galvanic isolation -> circuit isolation -> signal conditioning), optocouplers sit alongside digital isolators (capacitive, inductive) as a foundational circuit-protection element in PLCs, motor drivers, switch-mode power supply feedback loops, and communication-interface cards.
Key differentiating specifications include 3750 Vrms minimum isolation voltage (per UL 1577), a collector-emitter voltage (VCEO) rating of 80 V, and a collector current (IC) capability of 50 mA. The CTR rank 'GB' defines the IF=5 mA current transfer ratio between 100% and 600%, distinguishing it from the GR rank (100%-300%) and BL rank (200%-600%). The device is supplied in tape-and-reel packaging (TPL suffix) with embossed taping, optimized for high-density surface-mount assembly lines.
Architecturally, the TLP183 uses a GaAs infrared emitting diode (λp ≈ 940 nm) coupled through a transparent silicone optical bond to a silicon NPN phototransistor. The pair is mounted in opposing lead-frame cavities separated by a transparent insulating barrier, delivering both high common-mode transient immunity (CMTI) and creepage/clearance distances that meet 3750 Vrms reinforced-insulation requirements in most pollution-degree-2 industrial environments.
Typical applications include PLC digital input modules, AC adapter feedback loops, I/O interface boards, programmable-controller signal conditioning, and office-machine interface isolation. The wide operating temperature range also supports outdoor and industrial-automation equipment. This part is the GB-rank variant; the GR, BL, and blank-rank variants of the same TLP183 family share the footprint but offer different CTR windows for different bias-point designs.
When designing with the TLP183, observe the absolute-maximum IF of 50 mA through the input LED and the absolute-maximum VCEO of 80 V at the transistor output. A base-emitter resistor of approximately 1 MΩ is recommended across the B-E junction to improve high-temperature dark-current behavior, and a 100 kΩ pull-up on the collector is typical for digital-logic interfacing.

Aplicaciones típicas
TLP183(GB-TPL,E es adecuado para 6 aplicacións: PLC Digital Input Module, AC Adapter Feedback Loop, I/O Interface Board, Office Machine Interface, Communication Interface Card, Industrial Sensor Signal Conditioning.
PLC Digital Input Module
The TLP183(GB-TPL,E is the Toshiba-recommended optocoupler for 24V PLC digital-input modules because its 3750 Vrms isolation protects the backplane MCU from field-side transients up to IEC 61131-2 surge levels. Placed between the 24V field wiring and the MCU logic rail, the SO6 4-lead footprint enables high-density 16- or 32-channel input cards. The GB CTR rank (100%-600% at IF=5 mA) reliably biases the phototransistor into saturation when paired with a 4.7 kΩ input resistor at the standard 24V nominal, ensuring logic-low noise margin even with cold-crank dips to 18V. The wide -55°C to +125°C operating range supports outdoor cabinet installations without derating.
Recomendado
AC Adapter Feedback Loop
In isolated AC-DC adapter designs the TLP183(GB-TPL,E provides primary-to-secondary isolation in the feedback path, returning TL431-style error information across the 3750 Vrms safety barrier without ground loops. The 80V VCEO rating handles the inductive kickback seen on the secondary side during MOSFET switching edges, while the GB CTR window supports typical bias currents of 5-10 mA in linear-region feedback designs. Compared with digital isolator alternatives, the TLP183 adds zero common-mode switching noise to the feedback signal - a benefit for low-ripple-output adapter designs targeting <30 mV pp ripple.
Recomendado
I/O Interface Board
I/O interface boards in industrial PCs and modular DAQ systems use the TLP183(GB-TPL,E to galvanically isolate USB-to-24V or RS-232-to-24V signal paths. The SO6 (4-lead) footprint enables four-signal-per-cm² packing density, matching the pitch of common 2.54 mm header connectors. Its 3750 Vrms isolation meets EN 61010-1 reinforced-insulation requirements for measurement, control, and laboratory equipment. The 50 mA collector current capacity directly drives relay coils, small solenoids, and logic-level shifters on the field side without an additional buffer stage.
Recomendado
Office Machine Interface
Office machines (printers, copiers, multifunction devices) use the TLP183(GB-TPL,E to isolate the 24V motor-driver wiring from the 3.3V MCU control bus. The 3750 Vrms isolation protects logic-side ICs from the inductive load-dump transients generated by stepper motors, solenoids, and fuser heaters. With a 80V VCEO rating, the phototransistor can pull down signals riding on the +24V field rail, simplifying BOM by eliminating external driver transistors. The SO6 package reflows cleanly on standard lead-free profiles, fitting high-volume SMT lines.
Recomendado
Communication Interface Card
Communication interface cards (RS-485, CAN, Ethernet isolators) use the TLP183(GB-TPL,E in dedicated isolation paths for control-side handshake signals, status LEDs, and watchdog-reset lines. The 3750 Vrms barrier protects downstream logic from bus-side faults while the GB CTR window provides clean logic transitions for 10 kHz-class control signals. Combined with a digital isolator for the high-speed data path, the TLP183 handles the slow-control and supervisory signaling without introducing propagation-delay mismatches, simplifying timing budgets for protocol-compliant designs.
Recomendado
Industrial Sensor Signal Conditioning
Industrial analog sensor front-ends use the TLP183(GB-TPL,E in linear-region operation to transmit 4-20 mA current-loop signals across an isolation barrier, preserving 4-20 mA loop integrity for process-control instrumentation. The 80V VCEO accommodates loop-common-mode voltages up to industrial ±50V rails, and the GB CTR window (100%-600%) provides linear transfer across the input current range when biased at IF=5 mA. Compared with dedicated isolation amplifiers, the TLP183 cost is 50-70% lower at the expense of narrower bandwidth, making it ideal for DC and slow-varying process signals (temperature, pressure, level).

Notas de diseño
Estimated: when driven by a 24V PLC input with a 4.7 kΩ input resistor, the LED forward current IF is approximately (24V - 1.25V)/4.7 kΩ ≈ 4.8 mA, placing the part within its GB-rank CTR characterization window. Avoid pulling the input resistor below 2.2 kΩ since the absolute max IF of 50 mA can be exceeded during input transients; a TVS clamp (e.g. 24V bidirectional) on the input prevents field-side surge damage to the LED die.
Maintain minimum 5 mm keep-out under and around the SO6 package cavity (no copper traces, planes, or vias on any layer directly beneath the optocoupler body) to preserve the 3750 Vrms isolation. The Toshiba recommended land pattern uses 0.95 mm pitch with 0.6 mm × 0.3 mm pads. For double-sided boards, route field-side and logic-side traces on different layers with no overlap, and use the SO6 mechanical outline as the keep-out boundary.
Add a 100 kΩ pull-up resistor on the collector to VCC (typically 3.3V or 5V) and a 1 MΩ base-emitter resistor across pins 4 and 5 to suppress dark-current leakage at high temperature. Use a 100 pF to 1 nF base-emitter capacitor only if bandwidth-limiting is acceptable; otherwise omit it to preserve rise/fall times (~3 µs / 4 µs typical). For high-noise environments, place a 100 nF bypass capacitor directly at the collector pin to VCC.
Estimated: at IF=20 mA (typical bias), the LED junction dissipates approximately 20 mA × 1.4V ≈ 28 mW; the phototransistor collector dissipates up to IC × VCE = 50 mA × 80V = 4 W in the absolute-maximum case but typically <50 mW in linear-region designs. The SO6 package theta_JA is approximately 200°C/W on a 1 oz 2-layer FR4 board with minimum thermal lands; designers should derate IF to 10 mA at +100°C ambient for long-life industrial reliability.
