Toshiba Semiconductor and Storage TLP5772(D4,E

Overview

TLP5772(D4,E) from Toshiba Electronic Devices & Storage Corporation is a reinforced-insulation photocoupler integrating an infrared LED and high-speed photodetector in a 6-pin SO6L package. It delivers ±2.5 A peak output current, 150 ns max propagation delay, ±35 kV/µs common-mode transient immunity, and operates across -40°C to +110°C - enabling direct microcontroller drive in compact motor drivers and industrial inverters.

For engineers reviewing the TLP5772(D4,E) datasheet, TLP5772(D4,E) pinout, TLP5772(D4,E) application, or TLP5772(D4,E) equivalent, key selection criteria include its VDE-approved reinforced insulation (EN IEC 60747-5-5), rail-to-rail totem-pole output, low 2 mA max threshold input current, and 5000 Vrms isolation voltage for safety-critical gate driving.

Technical Context

The TLP5772(D4,E) implements a monolithic photo-IC architecture with internal Faraday shielding, enabling guaranteed ±35 kV/µs common-mode transient immunity. Its totem-pole output stage supports rail-to-rail switching between VCC (10–30 V) and GND, delivering ±2.5 A peak current into capacitive loads.

This device operates as a logic-output isolator with defined truth table behavior: LED ON drives output high (VO ≈ VCC); LED OFF drives output low (VO ≈ 0 V). It requires a 1 µF bypass capacitor between pins 6 (VCC) and 4 (GND) to stabilize the high-gain amplifier and ensure reliable switching at up to 50 kHz.

FAQ

What safety certifications apply to the TLP5772(D4,E)?

The TLP5772(D4,E) carries VDE approval per EN IEC 60747-5-5 (Option D4), UL recognition per UL 1577 (File E67349), and cUL certification per CSA Component Acceptance Service No. 5A File E67349. These confirm compliance with reinforced insulation requirements for industrial equipment operating up to 5000 Vrms working voltage. The "(D4)" suffix explicitly denotes VDE qualification.

Does the TLP5772(D4,E) require an external bypass capacitor?

Yes - a 1 µF ceramic capacitor must be placed between pin 6 (VCC) and pin 4 (GND), located within 1 cm of both pins. This stabilizes the internal high-gain amplifier and prevents oscillation or erratic switching. Omission causes unreliable output behavior, especially at high frequencies or elevated temperatures. The TLP5772(D4,E) datasheet mandates this in Section 6 and Section 9.

Can the TLP5772(D4,E) directly drive IGBT gates without a buffer stage?

Yes - the TLP5772(D4,E) delivers ±2.5 A peak output current and rail-to-rail VO swing (0 V to VCC), enabling direct connection to IGBT or MOSFET gates in motor drives and inverters. Its 2 mA max threshold input current allows direct MCU GPIO drive, eliminating external buffers. This capability is confirmed in Sections 2, 3, and 10 of the TLP5772(D4,E) datasheet.

What is the meaning of "(D4,E)" in the TLP5772(D4,E) part number?

The "(D4,E)" suffix indicates two specific qualifications: "D4" designates compliance with EN IEC 60747-5-5 Option D4 for reinforced insulation, verified by VDE; "E" denotes RoHS-compliant, lead-free construction. This exact marking appears in Toshiba's Ordering Information table (Section 18) and confirms the unit meets both safety and environmental requirements for industrial deployment.

How does the TLP5772(D4,E) achieve ±35 kV/µs common-mode transient immunity?

The TLP5772(D4,E) integrates an internal Faraday shield between input and output die, physically blocking capacitive coupling of fast transients. This structure is specified in Section 2 and validated in Section 12 (CMH/CML test conditions), guaranteeing ±35 kV/µs minimum immunity - a value measured under 1000 Vp-p common-mode step with defined load conditions, not extrapolated or estimated.
