Product details
Overview
TLP170AM(V4TPL,E) from Toshiba Electronic Devices & Storage Corporation is a halogen-free, normally-open photorelay in a 4-pin SO6 (11-4M1S) package, integrating an infrared LED and photo-MOSFET. It delivers 700 mA max ON-state current, 0.3 Ω max ON-resistance, and 60 V min OFF-state voltage-enabling solid-state replacement of mechanical relays in industrial I/O interfaces and PLC output stages.
For engineers reviewing the TLP170AM(V4TPL,E) datasheet, TLP170AM(V4TPL,E) pinout, TLP170AM(V4TPL,E) application, or TLP170AM(V4TPL,E) equivalent, key selection criteria include isolation voltage (3750 Vrms), trigger LED current (≤1 mA), VDE-compliant EN 60747-5-5 certification (enabled by V4 option), and SO6 surface-mount compatibility for high-density control board layouts.
Technical Context
The TLP170AM(V4TPL,E) implements a single-channel, optically isolated MOSFET switch with galvanic separation between input LED and output photo-MOSFET. Its internal structure treats Pins 1/3 as a common anode-cathode pair and Pins 4/6 as paralleled drain terminals-functioning as a true two-terminal output device.
It operates under recommended conditions of 2–48 V supply voltage and −40°C to +85°C ambient temperature, with switching times of 3–6 ms (turn-on) and 0.4–1 ms (turn-off) at 20 V and 2 mA LED drive-optimized for low-speed, high-reliability on/off control rather than signal switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 3750 Vrms (min, AC/60 s): Enables safe interface between 24 V DC control logic and 48 V industrial field-side circuits. |
| ON-State Current | 700 mA (max, continuous): Supports direct driving of solenoids, indicator lamps, and small actuators without external amplification. |
| ON-State Resistance | 0.3 Ω (max): Limits conduction loss to ≤150 mW at 700 mA-reducing thermal stress and eliminating need for heatsinking in most applications. |
| Trigger LED Current | 1 mA (max): Allows direct drive from low-power microcontroller GPIOs without series resistor recalibration. |
| OFF-State Voltage | 60 V (min): Withstands transient surges in factory automation environments where 24/48 V systems experience load-dump spikes. |
| Switching Time | tON = 3–6 ms, tOFF = 0.4–1 ms: Matches mechanical relay timing for drop-in replacement in legacy ladder logic systems. |
| Safety Certification | VDE EN 60747-5-5 (with V4 option), UL 1577, cUL CSA 5A: Meets reinforced insulation requirements for Category II industrial equipment. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 & 3 (shorted) | Anode / Cathode | Input LED terminals-Pins 1 and 3 are internally bonded as a single anode-cathode pair; requires external series resistor for current limiting. |
| 4 & 6 (shorted) | Drain (output) | Output MOSFET drain terminals-Pins 4 and 6 are internally paralleled to share current and reduce effective RDS(on). |
Key Features
| Feature | Design Value |
|---|---|
| VDE-certified isolation | EN 60747-5-5 compliance (enabled by V4 suffix) ensures reinforced insulation for CE-marked industrial controllers. |
| Low trigger threshold | ≤1 mA IFT enables direct MCU GPIO drive-eliminates need for buffer transistors in 3.3 V/5 V logic systems. |
| High output current capability | 700 mA continuous rating supports direct switching of 24 V solenoids, pilot lights, and small contactor coils. |
| Halogen-free construction | Meets IEC 61249-2-21:2017; encapsulant contains Br/Cl/Sb ≤0.09 wt%, total halogens ≤0.15 wt%-compliant with green manufacturing standards. |
| Normally-open (1-Form-A) | De-energized state is open-circuit-provides fail-safe behavior in safety-critical I/O modules where default-off is required. |
Applications
| Security Systems | Factory Automation (FA) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP170G(V4TPL,E) | Same SO6 package and VDE option, but rated for 1 A ON-current and 0.25 Ω RON; higher IFP (1.5 A pulsed) and larger die size. | Supports higher-power loads (e.g., 48 V solenoids); requires marginally higher LED drive (IFT = 1.5 mA max) and dissipates more heat at full load. | Select when >700 mA continuous current or lower RON is required; verify thermal layout supports 0.5 W dissipation. |
| PVG612AR | SO6 photorelay from Vishay; 600 mA max ION, 0.4 Ω RON, 60 V VOFF, UL/cUL only (no VDE), 1.2 mA IFT. | Lacks EN 60747-5-5 certification; suitable for non-VDE markets; slightly slower switching (tON = 8 ms typ.) and higher trigger current. | Choose for cost-sensitive UL-only designs where VDE compliance is not mandated; confirm system-level surge testing covers missing VDE validation. |
Compared with TLP170G(V4TPL,E), the TLP170AM(V4TPL,E) offers tighter trigger current control (≤1 mA vs. ≤1.5 mA) and lower thermal budget, while PVG612AR provides UL-only qualification at reduced performance-making TLP170AM(V4TPL,E) optimal for VDE-mandated, medium-current industrial I/O where precision triggering and thermal efficiency are prioritized.

FAQ
What is the isolation voltage rating of the TLP170AM(V4TPL,E) and how is it tested?
The TLP170AM(V4TPL,E) has a minimum isolation voltage of 3750 Vrms, tested per UL 1577 and VDE EN 60747-5-5 standards using AC voltage applied for 60 seconds at ≤60% relative humidity. This rating applies across the input-output barrier and confirms reinforced insulation for use in industrial equipment up to 48 V working voltage. The V4 option enables formal VDE certification.
Does the TLP170AM(V4TPL,E) require an external current-limiting resistor on the LED side?
Yes, the TLP170AM(V4TPL,E) requires an external series resistor to limit input forward current to ≤30 mA absolute maximum (recommended ≤25 mA). For example, with a 5 V supply and typical VF of 1.27 V, a 150 Ω resistor sets IF ≈ 25 mA. This prevents LED degradation and ensures reliable triggering at ≤1 mA IFT over temperature.
How does the V4 option affect the TLP170AM(V4TPL,E) compared to standard TLP170AM variants?
The V4 option denotes formal VDE EN 60747-5-5 approval-verified through third-party testing of creepage, clearance, internal isolation thickness, and partial discharge. Standard TLP170AM parts lack this certification. The V4 marking appears in the part number (e.g., TLP170AM(V4TPL,E)) and is required for CE-marked industrial equipment sold in EU markets.
Can the TLP170AM(V4TPL,E) switch AC loads directly?
No, the TLP170AM(V4TPL,E) is a unidirectional photo-MOSFET with a single output channel rated for DC loads only. Its 60 V OFF-state voltage and 700 mA ON-current apply to DC applications. For AC switching, a back-to-back MOSFET configuration (e.g., TLP3554) or external TRIAC driver is required.
What is the thermal derating behavior of the TLP170AM(V4TPL,E) at elevated ambient temperatures?
The TLP170AM(V4TPL,E) derates linearly above 25°C: ON-state current decreases by 8.3 mA/°C, and output power dissipation drops by 4.0 mW/°C. At 85°C ambient, the maximum continuous ION is reduced to approximately 220 mA. Thermal design must account for this-PCB copper area and airflow should maintain case temperature ≤85°C under full load.
