TLP358F(D4,F) Equivalent & Substitute Parts

Part Overview

The TLP358F(D4,F) is a logic output optoisolator manufactured by Toshiba Semiconductor and Storage, designed for applications requiring high-voltage isolation with push-pull, totem pole output configuration. This component features 3750Vrms isolation voltage, 20kV/µs common mode transient immunity, and 6A output current capability in an 8-DIP through-hole package.

The TLP358F(D4,F) is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems and new designs requiring comparable performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP358F(D4,F) is determined by the following critical parameters:

Isolation Voltage: The substitute must maintain isolation voltage at or above 3750Vrms to preserve electrical safety margins and regulatory compliance.

Common Mode Transient Immunity (CMTI): The substitute must support CMTI of at least 20kV/µs to ensure stable operation in high-speed switching environments.

Output Configuration: The substitute must provide push-pull or totem pole output topology to maintain circuit compatibility.

Output Current: The substitute must deliver a minimum of 6A output current per channel to support load requirements.

Supply Voltage Range: The substitute must operate within the 15V to 30V supply voltage window.

Operating Temperature Range: The substitute must support operation across -40°C to 100°C minimum.

Single Channel Configuration: The substitute must be a single-channel optoisolator.

The TLP5754(D4-LF4,E) meets these substitution criteria with enhanced performance characteristics in isolation voltage (5000Vrms), CMTI (35kV/µs), and operating temperature range (-40°C to 110°C). However, the TLP5754 utilizes surface mount packaging (6-SOIC) rather than through-hole packaging, requiring circuit board redesign for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The TLP5754(D4-LF4,E) is the recommended substitute for the TLP358F(D4,F) based on active product status and enhanced electrical performance. The TLP5754 exceeds all critical electrical parameters of the TLP358F, including isolation voltage, CMTI, and propagation delay specifications.

Compliance and Certification: The TLP5754(D4-LF4,E) carries multiple approval agencies including CQC, CSA, cUL, UL, and VDE, providing broader regulatory acceptance compared to the obsolete TLP358F(D4,F).

Packaging Consideration: Direct pin-for-pin substitution is not possible due to package format differences (8-DIP through-hole versus 6-SOIC surface mount). Circuit board redesign is required to accommodate the TLP5754 footprint.

Performance Enhancement: The TLP5754 delivers superior propagation delay (150ns versus 500ns) and improved CMTI (35kV/µs versus 20kV/µs), enabling operation in higher-speed switching applications.

Output Current Capability: The TLP5754 provides 4A peak output current, which is lower than the TLP358F 6A specification. Applications requiring the full 6A output current of the TLP358F must evaluate load requirements against the TLP5754 4A capability.

Frequently Asked Questions (FAQ)

Q: Can the TLP5754(D4-LF4,E) directly replace the TLP358F(D4,F) without circuit modification?

A: No. The TLP358F(D4,F) uses 8-DIP through-hole packaging while the TLP5754(D4-LF4,E) uses 6-SOIC surface mount packaging. Circuit board redesign is required to accommodate the different footprint and pin configuration.

Q: What are the key electrical differences between these two parts?

A: The TLP5754 provides higher isolation voltage (5000Vrms versus 3750Vrms), superior CMTI (35kV/µs versus 20kV/µs), and faster propagation delay (150ns versus 500ns). The TLP358F delivers higher output current (6A versus 4A peak).

Q: Is the TLP5754(D4-LF4,E) suitable for applications requiring 6A output current?

A: The TLP5754 provides 4A peak output current and 3A continuous output current (high and low). Applications requiring sustained 6A output current must evaluate whether the TLP5754 meets load requirements or if alternative components are necessary.

Q: What is the operating temperature range difference?

A: The TLP358F operates from -40°C to 100°C, while the TLP5754 operates from -40°C to 110°C. The TLP5754 provides an additional 10°C upper temperature margin.

Q: Are both parts manufactured by the same company?

A: Yes. Both the TLP358F(D4,F) and TLP5754(D4-LF4,E) are manufactured by Toshiba Semiconductor and Storage, ensuring consistent design philosophy and quality standards.

Q: What regulatory approvals does the TLP5754 carry?

A: The TLP5754(D4-LF4,E) holds approvals from CQC, CSA, cUL, UL, and VDE, providing compliance for multiple international markets and applications.

Q: Can the TLP358F be used in new designs?

A: The TLP358F(D4,F) is classified as obsolete. New designs should utilize the active TLP5754(D4-LF4,E) to ensure long-term supply availability and ongoing manufacturer support.

Q: What is the moisture sensitivity level of the TLP5754?

A: The TLP5754(D4-LF4,E) has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
