Toshiba Semiconductor and Storage TLP5701(D4-TP4,E

Overview

TLP5701(D4-TP4,E) from Toshiba Electronic Devices & Storage Corporation is a reinforced-insulation photocoupler with infrared LED input and integrated photo IC output in a 6-pin SO6L package. It delivers ±0.6 A peak output current, 500 ns max propagation delay, ±20 kV/µs common-mode transient immunity, and 5000 Vrms isolation voltage. It serves as a gate driver for small-class IGBTs and power MOSFETs in industrial inverters and induction cooktops.

For engineers reviewing the TLP5701(D4-TP4,E) datasheet, TLP5701(D4-TP4,E) pinout, TLP5701(D4-TP4,E) application, or TLP5701(D4-TP4,E) equivalent, key selection criteria include guaranteed CMOS-compatible totem-pole output, -40°C to +110°C operating range, UVLO protection, 10–30 V supply voltage, and VDE EN IEC 60747-5-5 certification for reinforced insulation.

Technical Context

The TLP5701(D4-TP4,E) integrates an infrared LED optically coupled to a high-gain, high-speed photodetector IC with totem-pole (buffer logic) output stage. Its internal noise shield ensures ±20 kV/µs common-mode transient immunity, critical for noisy power-conversion environments.

It features under-voltage lockout (UVLO) with 8.4 V turn-on and 8.1 V turn-off thresholds, operates from 10–30 V supply, and requires a 0.1 µF bypass capacitor between VCC (Pin 6) and GND (Pin 4). The device is rated for reinforced insulation per EN IEC 60747-5-5 when ordered with D4 option - explicitly confirmed for TLP5701(D4-TP4,E).

FAQ

What safety certifications apply to the TLP5701(D4-TP4,E)?

The TLP5701(D4-TP4,E) carries VDE approval per EN IEC 60747-5-5 and EN IEC 62368-1 for reinforced insulation, plus UL 1577 and cUL recognition. The "D4" suffix explicitly denotes qualification to the VDE standard - confirmed in Toshiba's ordering guide and datasheet Section 17. This makes TLP5701(D4-TP4,E) suitable for Class I equipment requiring certified reinforced insulation in EU and global markets.

Does the TLP5701(D4-TP4,E) require an external bypass capacitor?

Yes - a 0.1 µF ceramic capacitor must be placed between Pin 6 (VCC) and Pin 4 (GND), located within 1 cm of both pins. This is mandatory per Toshiba's Recommended Operating Conditions (Section 9) to stabilize the high-gain photodetector amplifier. Omitting it risks improper switching, oscillation, or latch-up. The TLP5701(D4-TP4,E) does not function reliably without this capacitor.

What is the maximum recommended operating temperature for the TLP5701(D4-TP4,E)?

The TLP5701(D4-TP4,E) is fully specified and guaranteed over -40°C to +110°C ambient temperature (Section 2, General). Absolute maximum junction temperature is 125°C, and thermal derating begins above 95°C per Absolute Maximum Ratings (Section 8). For continuous operation in industrial environments, TLP5701(D4-TP4,E) maintains all electrical parameters including ±20 kV/µs CMTI and ±0.6 A output up to +110°C.

Can the TLP5701(D4-TP4,E) drive a 1200 V IGBT directly?

No - the TLP5701(D4-TP4,E) is optimized for small-class IGBTs and power MOSFETs, with ±0.6 A peak output current and 35 V absolute max output voltage (VO). It is not rated for direct drive of 1200 V IGBTs, which typically require >2 A peak gate current and higher Miller clamping robustness. Use TLP5701(D4-TP4,E) only with IGBTs rated ≤600 V and gate charge ≤150 nC, as validated in Toshiba's application examples.

What is the purpose of Pin 2 (N.C.) on the TLP5701(D4-TP4,E)?

Pin 2 on the TLP5701(D4-TP4,E) is a no-connect terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB: no trace, via, solder mask opening, or copper pour may contact Pin 2. This is explicitly stated in the Pin Assignment diagram (Section 5) and ensures proper creepage distance and isolation integrity. Bridging or routing to Pin 2 voids safety certification.
