TBSL40J-TP Bridge Rectifier Single Phase 600V 4A Surface Mount

Part Overview

The TBSL40J-TP is a single-phase bridge rectifier diode manufactured by Micro Commercial Co, rated for 600V peak reverse voltage and 4A average rectified current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Bridge rectifiers in this voltage and current class are widely used in AC-to-DC conversion applications requiring standard rectification performance.

Parameter Comparison

Engineering Selection Recommendations

The Z4DGP406L-HF is suitable as a substitute for the TBSL40J-TP based on the following factors:

• Electrical Equivalence: Both components share identical voltage and current ratings (600V, 4A), with the Z4DGP406L-HF demonstrating superior forward voltage performance (950 mV vs. 1V @ 4A).
• Compliance Alignment: Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage requirements.
• Product Availability: The Z4DGP406L-HF is in active production status with substantial inventory availability (16,731 pcs), whereas the TBSL40J-TP is obsolete.
• Operating Temperature: The Z4DGP406L-HF supports an extended upper temperature limit (-55°C ~ 175°C TJ) compared to the main part (-55°C ~ 150°C), providing additional thermal margin in applications approaching maximum operating conditions.
• Package Compatibility: Both components utilize surface mount technology with 4-lead configurations suitable for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Z4DGP406L-HF directly replace the TBSL40J-TP in existing designs?

A: Yes. Both components meet the same electrical specifications for single-phase bridge rectification at 600V and 4A ratings. The Z4DGP406L-HF exhibits lower forward voltage (950 mV vs. 1V), which reduces power dissipation and improves efficiency. Surface mount compatibility is maintained across both parts.

Q: What is the significance of the forward voltage difference (950 mV vs. 1V)?

A: The Z4DGP406L-HF operates at 50 mV lower forward voltage at the 4A operating point. This results in reduced power loss and heat generation in the rectifier stage, which is beneficial for thermal management in continuous-duty applications.

Q: Are there package footprint considerations when substituting?

A: The TBSL40J-TP uses a 4-SMD flat lead package, while the Z4DGP406L-HF uses the Z4-D package. Both are surface mount configurations with four leads. PCB layout verification is necessary to confirm footprint compatibility, as package dimensions may differ despite functional equivalence.

Q: Does the extended operating temperature range of the Z4DGP406L-HF affect substitution suitability?

A: The Z4DGP406L-HF supports operation to 175°C (TJ) versus 150°C for the TBSL40J-TP. This extended range does not create incompatibility; it provides additional thermal headroom for applications operating near maximum temperature limits.

Q: What compliance certifications apply to both parts?

A: Both the TBSL40J-TP and Z4DGP406L-HF are ROHS3 compliant and carry MSL Level 1 (unlimited moisture sensitivity), indicating no special moisture control requirements during storage or handling.
