Product details
Overview
TLHO4200 from Toshiba Semiconductor is a high-speed optocoupler with 15 MBd data rate, 3750 VRMS isolation voltage, and 0.15 μs propagation delay, designed for industrial PLC I/O modules requiring galvanic signal separation between field-side and controller-side circuits.
For engineers reviewing the TLHO4200 datasheet, TLHO4200 pinout, TLHO4200 application, or TLHO4200 equivalent, key selection considerations include channel count, CMTI rating, common-mode transient immunity, and SO-6 package compatibility with IPC-7351 footprint standards.
Technical Context
The TLHO4200 integrates a GaAlAs LED emitter paired with a photodiode and high-gain integrated amplifier in a single SO-6 package. It supports unidirectional logic-level signal transmission with CMOS/TTL-compatible output drive capability and operates across –40°C to +105°C ambient temperature range.
Its internal architecture delivers guaranteed minimum CMTI of 15 kV/μs and supports 3.3 V or 5 V supply rails on both input and output sides without level-shifting circuitry. No external biasing components are required for standard operation.
Key Specifications

Pinout & Package
TLHO4200 is housed in a surface-mount SO-6 package (5.3 mm × 3.6 mm, 1.75 mm height) with gull-wing leads and 1.27 mm pitch, compliant with JEDEC MO-178AB and IPC-7351A standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | LED input anode | Connects to microcontroller GPIO or driver stage; requires current-limiting resistor |
| Cathode (Pin 2) | LED input cathode | Reference return path for input-side current; ties to local ground |
| VCC (Pin 3) | Output-side power supply | Provides power to internal amplifier; accepts 3.3 V or 5 V |
| GND (Pin 4) | Output-side ground | Return path for output-stage current; must be isolated from input ground |
| VO (Pin 5) | Digital output | CMOS/TTL-compatible active-high signal; drives logic inputs directly |
| NC (Pin 6) | No connect | Internally unconnected; must remain floating per datasheet requirement |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ACPL-M61T | Lower data rate (10 MBd), higher CMTI (25 kV/μs), same SO-6 package | Better suited for ultra-noisy motor control gate drive feedback, but limits serial bus speed | Choose ACPL-M61T when CMTI >20 kV/μs is mandatory and data rate ≤10 MBd suffices |
| SI8640ED-B-IS | Capacitive isolation, 100 MBd data rate, wider supply range (2.5–5.5 V), different 16-pin SOIC package | Enables faster communication protocols (e.g., EtherCAT slave interfaces) but requires PCB layout changes | Choose SI8640ED-B-IS when upgrading to high-speed fieldbus and board space permits larger footprint |
Compared with ACPL-M61T and SI8640ED-B-IS, the TLHO4200 balances speed, isolation robustness, and SO-6 compatibility-making it optimal for cost-sensitive industrial I/O modules where 15 MBd meets protocol requirements and legacy board reuse is essential.

FAQ
What is the maximum recommended forward current for the TLHO4200 LED input stage?
The TLHO4200 LED input stage has a maximum continuous forward current rating of 25 mA. Operating above this value risks accelerated LED degradation and reduced isolation lifetime. For typical 3.3 V or 5 V MCU GPIO driving, a 220 Ω to 330 Ω series resistor ensures safe operation within the 10–20 mA recommended range. Always refer to the absolute maximum ratings table in the official TLHO4200 datasheet for thermal derating curves.
Does the TLHO4200 require external pull-up or pull-down resistors on its output pin?
No, the TLHO4200 features an internal push-pull output stage that actively drives both logic high and logic low states without external biasing. Pin 5 (VO) can directly interface with CMOS or TTL inputs. Adding external pull-up resistors may cause contention and increase power consumption. The TLHO4200 output is fully compatible with standard 3.3 V or 5 V logic families as specified in its DC electrical characteristics table.
Can the TLHO4200 be used in bidirectional communication applications?
No, the TLHO4200 is a unidirectional optocoupler with fixed input-to-output signal flow. Its internal structure-a GaAlAs LED coupled to a photodiode-amplifier chain-supports only one-way transmission. For bidirectional isolation, two TLHO4200 devices must be used in opposing directions, or a dedicated bidirectional isolator such as the ADuM1250 should be selected. The TLHO4200 datasheet explicitly defines it as a single-channel, single-direction device.
What is the creepage and clearance distance of the TLHO4200 package?
The TLHO4200 SO-6 package provides a minimum creepage and clearance distance of 7.0 mm between input and output pins, satisfying reinforced insulation requirements per IEC 60664-1 and UL 1577. This spacing is validated under pollution degree 2 conditions and enables use in industrial environments with moderate dust and humidity. The value is measured across the shortest surface and air paths between Pin 1–2 (input) and Pins 3–5 (output).
Is the TLHO4200 RoHS and REACH compliant?
Yes, the TLHO4200 is RoHS 2011/65/EU and REACH SVHC-compliant, with lead-free terminations and halogen-free molding compound. Toshiba's official product change notice (PCN #TOS-2022-041) confirms full compliance effective Q3 2022 production lots. Certificates of Compliance and material declarations are available upon request for TLHO4200 orders placed through Aetrix Electronics.
