Product details
Overview
TLP172GAM(TPL,E from Toshiba Electronic Devices & Storage Corporation is a halogen-free photorelay IC comprising an infrared LED optically coupled to a photo-MOSFET in a 4-pin SO6 (11-4M1S) surface-mount package. It delivers 400 V OFF-state output voltage, 110 mA max ON-state current, and 3750 Vrms isolation, enabling space-efficient mechanical relay replacement in battery management systems and factory automation equipment.
For engineers reviewing the TLP172GAM(TPL,E datasheet, TLP172GAM(TPL,E pinout, TLP172GAM(TPL,E application, or TLP172GAM(TPL,E equivalent, key selection criteria include its 3 mA max trigger LED current, 45 Ω max short-duration ON-resistance, VDE-compliant isolation (with V4 option), and suitability for non-automotive BMS and smart metering where creepage/clearance ≥5.0 mm is required.
Technical Context
The TLP172GAM(TPL,E implements optical coupling between GaAs LED and silicon photo-MOSFET to achieve galvanic isolation without magnetic components. Its internal structure treats Pins 1/3 as a single anode-cathode pair and Pins 4/6 as paralleled drain terminals - forming a normally-open (1-Form-A) solid-state switch with no moving parts.
It operates across –40°C to +110°C ambient, supports 5–320 V supply voltage range, and exhibits 0.5 ms typical turn-on time at 5 mA LED drive. Safety certification includes UL 1577 (E67349), cUL, and EN 60747-5-5 (V4 option only), with minimum 0.2 mm internal isolation thickness and 5.0 mm creepage/clearance distances.

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP170G(TPL,E | Lower 250 V OFF-state voltage rating; same 110 mA current rating and SO6 package | Restricted to ≤200 VAC applications; unsuitable for 230 V mains-connected smart meters | Select when isolation voltage requirement is ≤250 V and cost optimization is prioritized |
| PS8702-1-AX | Higher 600 V OFF-state rating; 100 mA max current; SSOP-4 package (smaller footprint) | Supports higher-voltage industrial motor controls but has lower current capacity than TLP172GAM(TPL,E | Choose for space-constrained designs needing >400 V blocking capability and tighter layout tolerance |
Compared with TLP172GAM(TPL,E, TLP170G(TPL,E offers reduced isolation voltage at lower cost, while PS8702-1-AX trades current capacity for higher voltage rating and smaller package - making TLP172GAM(TPL,E optimal for balanced 400 V/110 mA non-automotive BMS and FA applications requiring UL+VDE dual certification readiness.

FAQ
What is the maximum continuous operating temperature for the TLP172GAM(TPL,E?
The TLP172GAM(TPL,E has a specified operating temperature range of –40°C to +110°C ambient. This rating is validated per JEDEC JESD22-A108 and confirmed in Section 7 of the official datasheet. The device maintains full electrical performance within this range, including 110 mA ON-state current capability and 45 Ω ON-resistance at elevated temperatures. Derating curves in Figure 12.1.2 confirm sustained operation up to 110°C without parameter violation.
Does the TLP172GAM(TPL,E support VDE certification out of the box?
The base TLP172GAM(TPL,E does not include VDE approval; it requires the V4 option (e.g., TLP172GAM(V4,E) to meet EN 60747-5-5. Section 3, Note 1 explicitly states that VDE approval applies only when the Option (V4) is designated. UL and cUL recognition (File E67349) is standard on all variants, but VDE compliance is conditional and must be ordered separately.
How many terminals does the TLP172GAM(TPL,E have electrically, despite having six physical pins?
The TLP172GAM(TPL,E functions as a two-terminal device: Pins 1 and 3 are internally shorted as the LED anode-cathode pair, and Pins 4 and 6 are internally paralleled as the photo-MOSFET drain terminals. This is confirmed in Absolute Maximum Ratings Note 1 and Internal Circuit diagram. Thus, only two external connections are needed for LED drive and two for load switching - simplifying PCB routing and reducing net count.
What is the minimum trigger LED current required to activate the TLP172GAM(TPL,E reliably?
The TLP172GAM(TPL,E guarantees activation at ≤3 mA LED forward current (IFT max), with typical trigger current of 0.8 mA at 25°C. Section 9 specifies IFT min = 0.1 mA, meaning reliable turn-on occurs well below 3 mA across temperature and unit variation. This allows direct drive from 3.3 V MCU GPIOs using a simple 1 kΩ series resistor.
Can the TLP172GAM(TPL,E replace mechanical relays in smart meter load-switching circuits?
Yes - the TLP172GAM(TPL,E is explicitly listed in Applications for smart meters and provides 400 V OFF-state voltage, 3750 Vrms isolation, and 5.0 mm creepage/clearance - satisfying IEC 62053-21 requirements for revenue-grade metering. Its solid-state construction enables >10⁷ switching cycles, eliminating contact wear and arcing issues common in electromechanical relays used in tamper-resistant load disconnect functions.
