Product details
Overview
TLP293(GR-TPL,E from Toshiba Electronic Devices & Storage Corporation is a GB-rank infrared LED and phototransistor photocoupler in SO4 (11-3C1) package, delivering 100% min current transfer ratio at IF = 0.5 mA/VCE = 5 V, 3750 Vrms isolation voltage, and operation from −55 °C to +125 °C - used for signal isolation in switching power supplies and PLC I/O interfaces.
For engineers reviewing the TLP293(GR-TPL,E datasheet, TLP293(GR-TPL,E pinout, TLP293(GR-TPL,E application, or TLP293(GR-TPL,E equivalent, key selection criteria include CTR rank GR certification, SO4 creepage/clearance ≥5.0 mm, UL/cUL/VDE safety approvals, and guaranteed saturation performance under 1 mA input drive.
Technical Context
The TLP293(GR-TPL,E implements optical coupling between a GaAs infrared LED and a silicon NPN phototransistor, with internal isolation structure validated per EN IEC 60747-5-5 (V4 option available). Its two-terminal functional model treats pins 1&2 as input anode/cathode and pins 3&4 as output emitter/collector.
It supports high-density surface mounting via SO4 package with 0.4 mm minimum internal insulation thickness and meets reinforced insulation requirements for industrial control systems operating up to 48 VCE with ≤0.3 V saturation voltage at IF = 1 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CTR Rank | GR: 100% min current transfer ratio at IF = 0.5 mA, VCE = 5 V - ensures reliable switching with low-input-current logic drivers. |
| Isolation Voltage | 3750 Vrms (60 s): enables safe galvanic separation between primary-side control and secondary-side power circuits. |
| Collector-Emitter Voltage | 80 V min: supports interface with 24 V and 48 V industrial bus systems without external clamping. |
| Operating Temperature | −55 °C to +125 °C: qualified for under-hood automotive modules and industrial motor drives with wide ambient swings. |
| Package | SO4 (11-3C1): 5.0 mm creepage/clearance, RoHS-compliant lead-free finish, tape-and-reel (TPL) packaging for automated SMT placement. |
| Switching Speed | Rise/fall time ≤3 µs (RL = 100 Ω, VCC = 10 V): suitable for PWM feedback loops up to ~100 kHz in SMPS designs. |
| Saturation Voltage | VCE(sat) ≤0.3 V at IC = 2.4 mA, IF = 8 mA: minimizes conduction loss in solid-state relay and I/O buffer applications. |
Pinout & Package
SO4 package (Toshiba designation: 11-3C1), surface-mount, 4-pin, gull-wing leads, 0.05 g typical weight, 5.0 mm creepage and clearance, 0.4 mm internal isolation thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode input - requires series resistor to limit IF to ≤50 mA DC or ≤1 A pulsed (PW ≤0.1 ms). |
| 2 | Cathode | LED cathode input - referenced to primary-side ground; reverse voltage rating 5 V max. |
| 3 | Emitter | Phototransistor emitter output - typically tied to secondary-side ground or pulled up via load resistor. |
| 4 | Collector | Phototransistor collector output - open-collector switch node capable of sinking ≥50 mA at VCE ≤ 0.3 V. |
Key Features
| Feature | Design Value |
|---|---|
| High CTR Rank GR | Guarantees ≥100% current transfer ratio at low 0.5 mA input - reduces drive circuit power and enables direct MCU GPIO interfacing. |
| Reinforced Isolation | 3750 Vrms withstand + EN IEC 60747-5-5 compliance (V4 option) - satisfies safety-critical insulation requirements for industrial equipment. |
| Wide Temperature Range | −55 °C to +125 °C operation - eliminates derating concerns in sealed enclosures or high-ambient environments like factory floors. |
| Low Saturation Voltage | VCE(sat) ≤0.3 V at rated output current - improves efficiency in solid-state output stages and reduces thermal stress on downstream components. |
| UL/cUL/VDE/CQC Certified | Single device certified to multiple global safety standards - simplifies international product certification and reduces BOM complexity. |
Applications
| Switching Power Supplies | Programmable Logic Controllers |
|---|---|
Use Scenario: Feedback loop isolation in AC/DC and DC/DC converters to separate primary-side controller from secondary-side sensing. IC Role / Device Role / Timing Role: Optically isolated error amplifier output stage transmitting PWM correction signals across isolation barrier. Use Value: Enables stable regulation while meeting IEC 62368-1 reinforced insulation requirements and supporting 100 kHz+ switching frequencies. |
Use Scenario: Digital input module isolating field sensors (e.g., limit switches, proximity sensors) from CPU backplane. IC Role / Device Role / Timing Role: Input stage optocoupler converting 24 V DC field signals into clean 3.3/5 V logic levels for FPGA or microcontroller inputs. Use Value: Prevents ground-loop noise and transient coupling from industrial environments, with guaranteed CTR stability over full temperature range. |
| I/O Interface Boards | Industrial Motor Drives |

IC Role / Device Role / Timing Role: Signal-level isolator for RS-485 enable/disable lines or digital status reporting paths. Use Value: Maintains signal integrity across noisy plant-floor wiring while enabling compact board layout due to SO4 footprint. |
Use Scenario: Gate drive isolation for IGBTs or MOSFETs in three-phase inverter stages. IC Role / Device Role / Timing Role: Low-speed control signal isolator for enable/disable, fault reporting, or mode selection - not gate driver replacement. Use Value: Provides fail-safe interlock signaling with 3750 Vrms isolation margin, compatible with 150 °C junction-rated power devices. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar photocoupler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP291(GB-TPL,E | Same SO4 package, but GB rank (100% min CTR at IF = 5 mA, not 0.5 mA); slightly higher VF (1.4 V max). | Better suited for higher-drive logic families; less ideal for ultra-low-power MCU GPIO sourcing. | Select TLP291(GB-TPL,E only if driving current ≥5 mA is available and low-input-current operation is not required. |
| PC817XNIP0X | DIP-4 package (not SO4); 5000 Vrms isolation; CTR 80–600% (no rank binning); no VDE/EN 60747-5-5 certification. | Larger footprint; lacks reinforced insulation validation for industrial safety standards; wider CTR distribution increases design margining effort. | Choose PC817XNIP0X only for cost-sensitive, non-certified consumer-grade applications where SO4 mounting is not required. |
Compared with TLP293(GR-TPL,E, the TLP291(GB-TPL,E offers identical packaging and safety ratings but requires higher input current for guaranteed CTR, while PC817XNIP0X trades miniaturization and regulatory compliance for lower unit cost in non-safety-critical roles.

FAQ
What does the "GR" suffix mean in TLP293(GR-TPL,E?
The "GR" in TLP293(GR-TPL,E denotes the Current Transfer Ratio (CTR) rank, guaranteeing a minimum CTR of 100% when tested at IF = 0.5 mA and VCE = 5 V. This rank ensures predictable low-current switching performance, making TLP293(GR-TPL,E suitable for direct interface with low-drive microcontroller outputs without external amplification.
Is TLP293(GR-TPL,E certified to VDE EN IEC 60747-5-5?
TLP293(GR-TPL,E is approved to EN IEC 60747-5-5 *when ordered with the V4 option*, e.g., TLP293(V4GR-TL,E. The base TLP293(GR-TPL,E carries UL 1577 and cUL recognition, plus CQC and EN IEC 62368-1 approval, but VDE certification requires explicit V4 designation per Toshiba's ordering specification.
What is the maximum recommended soldering temperature for TLP293(GR-TPL,E?
The peak soldering temperature for TLP293(GR-TPL,E is 260 °C for ≤10 seconds during flow soldering or single reflow. For hand soldering, use ≤260 °C for ≤10 seconds or ≤350 °C for ≤3 seconds per lead - consistent with J-STD-020 moisture sensitivity level (MSL) 3 handling guidelines specified in Toshiba's documentation for this SO4 device.
Can TLP293(GR-TPL,E replace TLP293(GB-TPL,E in existing designs?
TLP293(GR-TPL,E and TLP293(GB-TPL,E share identical SO4 package, pinout, and absolute maximum ratings, but differ in CTR test condition: GR is binned at IF = 0.5 mA, GB at IF = 5 mA. Substitution is acceptable only if the driving circuit delivers ≥0.5 mA reliably; otherwise, marginal turn-on may occur with GB-optimized designs.
Does TLP293(GR-TPL,E support 48 V collector-emitter operation?
Yes - TLP293(GR-TPL,E guarantees VCEO ≥80 V (min), with dark current IDARK ≤0.1 µA at VCE = 48 V and Ta = 85 °C. This allows safe use in 24 V and 48 V industrial control outputs, provided external pull-up resistors and load conditions maintain VCE within rated limits during all operational states.
