Toshiba Semiconductor and Storage TLP5702H(TP4,E

Overview

TLP5702H(TP4,E) from Toshiba Electronic Devices & Storage Corporation is a 6-pin SO6L photocoupler integrating an infrared LED and high-speed photodetector IC for isolated gate driving of IGBTs and power MOSFETs. It delivers ±2.5 A peak output current, 200 ns max propagation delay, ±50 kV/µs common-mode transient immunity, 5000 Vrms isolation voltage, and operates from -40°C to +125°C in PV inverters and industrial motor drives.

For engineers reviewing the TLP5702H(TP4,E) datasheet, TLP5702H(TP4,E) pinout, TLP5702H(TP4,E) application, or TLP5702H(TP4,E) equivalent, this device serves as a reinforced-insulation, buffer-output optocoupler optimized for high-noise, high-voltage gate drive where compact size, fast switching, and certified safety compliance are critical selection criteria.

Technical Context

The TLP5702H(TP4,E) implements a totem-pole output stage with internal noise shielding to achieve guaranteed ±50 kV/µs CMTI at up to 125°C ambient. Its input LED is optically coupled to a high-gain photodetector IC that drives a push-pull output capable of sourcing/sinking ±2.5 A peak into gate loads.

It requires a 0.1 µF bypass capacitor between VCC (Pin 6) and GND (Pin 4), supports 15–30 V supply, and features UVLO with 11.0 V turn-on and 9.5 V turn-off thresholds. The device meets UL 1577, CSA Component Acceptance, and EN IEC 60747-5-5 (with D4 option) for reinforced insulation.

FAQ

What is the maximum recommended operating temperature for the TLP5702H(TP4,E)?

The TLP5702H(TP4,E) is rated for continuous operation from -40°C to +125°C. This maximum junction temperature rating is validated per its absolute maximum ratings table and confirmed in the Recommended Operating Conditions section. Operation beyond 125°C ambient risks exceeding the 150°C absolute maximum junction temperature and may cause irreversible degradation. Thermal design must ensure adequate heatsinking or airflow to maintain Tj ≤ 150°C under worst-case load conditions.

Does the TLP5702H(TP4,E) require an external bypass capacitor?

Yes, the TLP5702H(TP4,E) requires a 0.1 µF ceramic bypass capacitor connected between Pin 6 (VCC) and Pin 4 (GND). This is explicitly mandated in Section 6 ("Internal Circuit") and Section 9 ("Recommended Operating Conditions") of the datasheet to stabilize the high-gain photodetector IC and prevent oscillation or improper switching. The capacitor must be placed within 1 cm of the pins; failure to install it will result in unreliable output behavior, especially at high frequencies or under load.

What safety certifications does the TLP5702H(TP4,E) hold?

The TLP5702H(TP4,E) is UL-recognized (UL 1577, File No. E67349), cUL-recognized (CSA Component Acceptance Service No. 5A, File No. E67349), and VDE-approved for EN IEC 60747-5-5 and EN IEC 62368-1 - but only when ordered with the D4 option (e.g., TLP5702H(D4-TP4,E)). The base TLP5702H(TP4,E) carries UL/cUL certification and meets reinforced insulation requirements per GB4943.1 in China and Thailand factories.

Can the TLP5702H(TP4,E) drive both IGBTs and MOSFETs?

Yes, the TLP5702H(TP4,E) is explicitly designed for small-to-medium-class IGBT and power MOSFET gate driving, as stated in Section 2 ("General"). Its ±2.5 A peak output current, 200 ns propagation delay, and totem-pole output architecture enable direct connection to the gate terminals of both device types without external buffers. Application notes confirm successful use with 600 V and 1200 V IGBTs and 650 V MOSFETs in inverter half-bridges.

What is the function of Pin 2 on the TLP5702H(TP4,E)?

Pin 2 on the TLP5702H(TP4,E) is designated N.C. (No Connection) and has no internal bond wire or circuit connection. It must remain electrically floating - no PCB trace, copper pour, or component should be attached to it. This is confirmed in Section 5 ("Pin Assignment") and Section 8 ("Absolute Maximum Ratings") Note 4, which states Pins 1, 2, and 3 are shorted together only in the context of two-terminal isolation testing, not functional operation.
