Product details

Overview

TLP3640A(V4TPL,E from Toshiba Electronic Devices & Storage Corporation is a halogen-free, VDE-qualified photorelay in SO4 (11-3C1) package, integrating an infrared LED optically coupled to a photo-MOSFET. It delivers 1 A 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 control and instrumentation.

For engineers reviewing the TLP3640A(V4TPL,E datasheet, TLP3640A(V4TPL,E pinout, TLP3640A(V4TPL,E application, or TLP3640A(V4TPL,E equivalent, key selection criteria include isolation voltage (3750 Vrms), trigger LED current (≤3 mA), operating temperature range (−40 to +110 °C), and EN IEC 60747-5-5 compliance for safety-critical designs.

Technical Context

The TLP3640A(V4TPL,E implements optical isolation between input LED and output photo-MOSFET, with internal pin shorting (Pins 1&2 = anode/cathode; Pins 3&4 = dual-drain output). Its normally-open (1-Form-A) configuration supports DC/AC load switching up to 60 V with sub-0.5 ms turn-on and 0.2 ms turn-off times at IF = 5 mA and RL = 200 Ω.

Designed for high-reliability industrial environments, it meets UL 1577 (File E67349), cUL CSA 5A (File E67349), and VDE EN IEC 60747-5-5 (Option V4) - validated by minimum creepage/clearance of 5.0 mm and insulation thickness of 0.2 mm. The device requires |dV/dt| ≤ 0.1 kV/µs on the output side during LED-OFF state for stable operation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar photorelay applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLP3642(V4TPL,E(T	Same SO4 package and V4 option, but rated for 1.5 A max ON-current and 0.15 Ω max R_ON	Better suited for higher-current loads (e.g., 48 VDC contactors), with tighter R_ON tolerance	Select TLP3642(V4TPL,E(T only if >1 A continuous load current or <0.2 Ω R_ON is required; otherwise TLP3640A(V4TPL,E offers cost and thermal advantage
PVG612A	SO6 package, 1.2 A max current, 0.25 Ω max R_ON, no VDE EN IEC 60747-5-5 certification	Lacks VDE safety approval; requires additional system-level validation for safety-critical use	Choose PVG612A only for non-safety-rated consumer or lab equipment where UL/cUL suffices and SO6 layout is acceptable

Compared with TLP3640A(V4TPL,E, TLP3642(V4TPL,E(T offers higher current capability but at increased cost and thermal demand, while PVG612A trades VDE certification for broader package availability - making TLP3640A(V4TPL,E the optimal balance of safety compliance, thermal efficiency, and industrial current handling.

FAQ

What safety certifications does the TLP3640A(V4TPL,E hold?

The TLP3640A(V4TPL,E holds UL 1577 (File E67349), cUL CSA Component Acceptance Service No.5A (File E67349), and VDE EN IEC 60747-5-5 (Option V4) certification. The "V4" suffix in the part number explicitly denotes VDE qualification, verified via minimum creepage/clearance of 5.0 mm and 3750 Vrms isolation voltage. These approvals enable its use in safety-rated PLC outputs and industrial control systems compliant with IEC 61508 SIL-2.

What is the maximum continuous load current supported by the TLP3640A(V4TPL,E?

The TLP3640A(V4TPL,E supports a maximum continuous ON-state current of 1 A at Ta ≤ 25 °C, derating linearly to 0 A at Ta = 125 °C. At 110 °C ambient (its maximum rated operating temperature), the usable current drops to approximately 0.7 A. This rating is validated under specified thermal conditions and must be applied with attention to PCB copper area and airflow - the device's 0.3 Ω max R_ON ensures ≤300 mW dissipation at full 1 A, minimizing self-heating.

How is the pin configuration structured on the TLP3640A(V4TPL,E?

The TLP3640A(V4TPL,E uses a 4-pin SO4 (11-3C1) package with internal pin shorting: Pins 1 and 2 form the LED anode/cathode pair, while Pins 3 and 4 are shorted together as the dual-drain output terminals of the photo-MOSFET. This two-terminal output configuration simplifies PCB layout and enhances current-handling symmetry. Pin 1 is marked with a dot or notch on the package body, and the land pattern must follow Toshiba's recommended dimensions (Fig. 14.1) to ensure reliable reflow soldering.

Does the TLP3640A(V4TPL,E support AC load switching?

Yes, the TLP3640A(V4TPL,E supports bidirectional AC load switching due to its photo-MOSFET output structure, which functions as a bilateral switch. Its 60 V min OFF-state voltage applies to both polarities, and it exhibits symmetric R_ON and switching characteristics. However, for AC mains applications (>60 V peak), external series blocking components (e.g., back-to-back MOSFETs or external relays) are required - the TLP3640A(V4TPL,E itself is rated for ≤60 V RMS or DC across its output terminals.

What is the significance of the "(V4TPL,E(T" suffix in TLP3640A(V4TPL,E?

The "(V4TPL,E(T" suffix in TLP3640A(V4TPL,E decodes as follows: V4 = VDE EN IEC 60747-5-5 qualification; TPL = tape-and-reel packaging (2500 pcs/reel); E = RoHS-compliant (lead-free); (T = manufactured in Thailand. This full ordering code identifies the exact variant qualified to VDE safety standards - distinct from standard TLP3640A variants lacking V4. For safety-critical designs, only the V4-suffixed version satisfies EN IEC 60747-5-5 requirements.
