Toshiba Semiconductor and Storage TLP2710(TP,E

Overview

TLP2710(TP,E) from Toshiba Electronic Devices & Storage Corporation is a high-speed 5-Mbps photocoupler with reinforced insulation, designed for signal isolation in industrial control interfaces. It features SO6L package (2.3 mm max height), 5 kV_rms isolation voltage, ±25 kV/µs common-mode transient immunity, and operates from 2.7 V to 5.5 V supply across –40°C to +125°C - enabling direct microcontroller drive in PLC and BMS applications.

For engineers reviewing the TLP2710(TP,E) datasheet, TLP2710(TP,E) pinout, TLP2710(TP,E) application, or TLP2710(TP,E) equivalent, key selection considerations include guaranteed propagation delay ≤250 ns, threshold input current ≤1.0 mA, low supply current (≤0.3 mA), and compliance with UL 1577, VDE EN IEC 60747-5-5 (with D4 option), and CQC GB4943.1.

Technical Context

The TLP2710(TP,E) integrates an infrared LED coupled to a photo IC detector with totem-pole output stage, supporting both current sourcing and sinking. Its internal Faraday shield ensures robust noise rejection in high dv/dt environments such as motor drives and inverters.

It delivers NRZ data transfer at 5 MBd with pulse width distortion ≤30 ns and propagation delay skew ≤65 ns between units. The device requires a 0.1 µF bypass capacitor between VDD (Pin 6) and GND (Pin 4), placed within 1 cm of the pins to stabilize high-gain switching behavior.

FAQ

What is the maximum recommended supply voltage for the TLP2710(TP,E)?

The TLP2710(TP,E) supports a supply voltage range of 2.7 V to 5.5 V on its VDD pin (Pin 6). Operation above 5.5 V risks exceeding absolute maximum ratings and may cause permanent damage. At 5.5 V, the device maintains full specification for output voltage levels (VOH ≥ VDD – 0.25 V) and supply current (IDDH ≤ 0.3 mA), making it compatible with standard 5 V logic systems while retaining compatibility with 3.3 V microcontrollers.

Does the TLP2710(TP,E) require an external bypass capacitor?

Yes - a 0.1 µF ceramic capacitor must be placed between Pin 6 (VDD) and Pin 4 (GND) of the TLP2710(TP,E), located within 1 cm of the pins. This capacitor stabilizes the internal photo IC's power rail during fast switching transitions; omission causes erratic output behavior, increased propagation delay variation, and potential failure to meet the specified 5 MBd data rate. The capacitor is mandatory per Toshiba's Recommended Operating Conditions and Test Circuit guidelines.

Can the TLP2710(TP,E) be used in safety-certified designs?

Yes - the TLP2710(TP,E) is UL 1577 recognized (File E67349), cUL certified, and CQC approved to GB4943.1. For VDE EN IEC 60747-5-5 compliance, the D4 option variant (e.g., TLP2710(D4-TP,E)) must be selected. The base TLP2710(TP,E) meets reinforced insulation requirements at 5 kV_rms, but full VDE certification requires explicit D4 ordering - critical for CE-marked industrial equipment requiring harmonized standard validation.

What is the function of Pin 2 (N.C.) on the TLP2710(TP,E)?

Pin 2 of the TLP2710(TP,E) is a no-connect (N.C.) terminal - internally unconnected and electrically isolated from all other circuitry. It must remain unconnected on the PCB; no trace, pad, or solder should be applied. This pin exists for mechanical symmetry and package compatibility and has zero electrical function. Connecting it risks compromising isolation integrity or inducing parasitic coupling in high-noise environments.

How does the TLP2710(TP,E) achieve ±25 kV/µs common-mode transient immunity?

The TLP2710(TP,E) achieves ±25 kV/µs common-mode transient immunity via an integrated Faraday shield between its input LED and output photo IC die. This conductive barrier blocks capacitive coupling of fast dv/dt noise across the isolation barrier, ensuring output stability even during 1000 V_p-p transients at 25 kV/µs slew rate. This performance is verified per IEC 60747-5-5 test methods and is essential for reliable operation in inverter gate drive and PLC backplane applications.
