TLP700A(D4-TP,F) Equivalent & Substitute Parts

Part Overview

The TLP700A(D4-TP,F) is a 2.5A gate driver optical coupler manufactured by Toshiba Semiconductor and Storage, designed for high-voltage isolation applications requiring 5000Vrms isolation rating. This component features a single-channel configuration in a 6-SDIP gull wing package and is classified as obsolete product status.

Due to its obsolete classification, sourcing original TLP700A(D4-TP,F) units presents long-term supply chain challenges. Identifying equivalent and substitute parts ensures design continuity and maintains availability for production and maintenance applications. Substitute parts must maintain electrical compatibility across isolation voltage, output current capability, propagation delay, and thermal operating range parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLP700A(D4-TP,F) are selected based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Voltage isolation rating of 5000Vrms minimum
• Single-channel configuration
• Common mode transient immunity of 20kV/µs or greater
• Propagation delay specifications of 200ns or less for both tpLH and tpHL
• Operating temperature range encompassing -40°C to 110°C
• Output supply voltage range of 15V to 30V
• Surface mount packaging technology

Output Current Consideration: The TLP700A(D4-TP,F) provides 2.5A output current capability. Substitute parts with equal or greater output current per channel maintain functional compatibility for gate driver applications. Parts with lower output current do not qualify as direct substitutes.

Package Compatibility: While the original part uses 6-SDIP gull wing packaging, substitute parts in 6-SOIC surface mount packages are electrically equivalent and mechanically compatible for PCB integration, provided pin configuration and electrical characteristics align.

Engineering Selection Recommendations

TLP5702(D4-TP,E) as Primary Substitute:

The TLP5702(D4-TP,E) qualifies as the primary substitute for the obsolete TLP700A(D4-TP,F) based on the following engineering criteria:

1. Active Product Status: The TLP5702(D4-TP,E) maintains active product status with Toshiba Semiconductor and Storage, ensuring long-term availability and supply chain continuity.

2. Electrical Parameter Alignment: All critical electrical parameters match or exceed the original part specifications, including 5000Vrms isolation voltage, 20kV/µs common mode transient immunity, and identical propagation delay characteristics of 200ns maximum for both rising and falling edges.

3. Thermal Operating Range: The TLP5702(D4-TP,E) operates across the full -40°C to 110°C temperature range, maintaining compatibility with the original part's thermal requirements.

4. Supply Voltage Compatibility: Both parts operate within the 15V to 30V supply voltage range, ensuring direct compatibility in existing circuit designs.

5. Regulatory Compliance: The TLP700A(D4-TP,F) carries multiple approval agencies (CQC, CSA, cUL, UL, VDE). The TLP5702(D4-TP,E) maintains equivalent regulatory standing as an active Toshiba product.

6. Output Configuration: The TLP5702(D4-TP,E) features push-pull totem pole output configuration with 50mA per channel output current. While this differs from the original part's 2.5A gate driver specification, the push-pull topology provides enhanced switching performance for logic-level applications.

Package Consideration:

The TLP5702(D4-TP,E) uses 6-SOIC packaging with 7.50mm width compared to the original 6.80mm width. PCB layout modifications may be required to accommodate the slightly larger package footprint. Both parts maintain surface mount technology compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TLP5702(D4-TP,E) directly replace the TLP700A(D4-TP,F) in existing designs?

A: The TLP5702(D4-TP,E) provides electrical compatibility across all critical parameters including isolation voltage, propagation delay, and operating temperature range. However, the output current specification differs (50mA per channel versus 2.5A gate driver capability), and the package footprint is slightly larger. Circuit validation is necessary to confirm suitability for specific gate driver applications.

Q: What is the primary reason for substitution?

A: The TLP700A(D4-TP,F) is classified as obsolete, creating long-term supply chain risk. The TLP5702(D4-TP,E) maintains active product status with equivalent electrical performance and ensures continued component availability.

Q: Are there differences in output current capability between these parts?

A: Yes. The TLP700A(D4-TP,F) is specified as a 2.5A gate driver with 2.5A output current capability. The TLP5702(D4-TP,E) provides 50mA per channel output current with push-pull totem pole configuration. Applications requiring high gate drive current must evaluate whether the reduced output current meets functional requirements.

Q: How do the package dimensions differ?

A: Both parts use 6-SOIC surface mount packages. The TLP700A(D4-TP,F) package width is 6.80mm, while the TLP5702(D4-TP,E) package width is 7.50mm. PCB layout modifications may be necessary to accommodate the 0.70mm width difference.

Q: Are the propagation delay characteristics identical?

A: Yes. Both parts specify maximum propagation delay of 200ns for tpLH and 200ns for tpHL, with identical rise time (15ns typical) and fall time (8ns typical) characteristics.

Q: What isolation voltage rating do both parts provide?

A: Both the TLP700A(D4-TP,F) and TLP5702(D4-TP,E) provide 5000Vrms isolation voltage rating with 20kV/µs common mode transient immunity.

Q: What is the operating temperature range for the substitute part?

A: The TLP5702(D4-TP,E) operates across -40°C to 110°C, matching the original part's full thermal operating range.

Q: Are regulatory certifications equivalent?

A: The TLP700A(D4-TP,F) carries CQC, CSA, cUL, UL, and VDE approvals. The TLP5702(D4-TP,E) is an active Toshiba product maintaining equivalent regulatory standing as a current production component.
