TS4K40 D3G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The TS4K40 D3G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for standard 400 V applications with 4 A average rectified current capacity. This component is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Bridge rectifiers of this specification are essential in power supply circuits, industrial equipment, and AC-to-DC conversion applications where reliable full-wave rectification is required. Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the through-hole mounting category.

Substitute Part Grouping Explanation

Substitute parts for the TS4K40 D3G are identified based on the following critical parameters that determine functional equivalence:

Matching Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 400 V
• Mounting Type: Through Hole
• Package / Case: 4-SIP, GBL
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS3 Compliance: Required

Current Rating Consideration: The TS4K40 D3G specifies 4 A average rectified current. Substitute parts with equal or greater current capacity at the specified voltage rating are classified as direct equivalents. Parts with lower current ratings may be used in applications with reduced current demands but do not constitute full parametric equivalence.

Forward Voltage Tolerance: Forward voltage drop variations within standard rectifier specifications do not preclude substitution, provided the part operates within the same voltage class and temperature range.

Parameter Comparison

Engineering Selection Recommendations

TS4K40 D3G (Primary Component)

The TS4K40 D3G remains the specified component for applications requiring the full 4 A average rectified current rating at 400 V peak reverse voltage. This part is active, RoHS3 compliant, and carries unlimited moisture sensitivity rating, making it suitable for standard industrial and commercial power supply applications without environmental restrictions.

GBL04 (SURGE) - Conditional Substitute

The GBL04 is a parametric equivalent in voltage class, temperature range, package configuration, and compliance status. However, the GBL04 specifies a 3 A average rectified current rating compared to the TS4K40 D3G's 4 A rating. This part is suitable for applications where the circuit design accommodates a maximum 3 A load current. Both parts share identical reverse leakage characteristics, operating temperature range, and RoHS3 compliance. The GBL04 is active and available in higher inventory volume (1045 Pcs vs. 830 Pcs).

Compliance and Certification Alignment

Both parts maintain RoHS3 compliance and MSL Level 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage protocols. The TS4K40 D3G carries EAR99 export classification, while the GBL04 carries 3A001 classification; these designations do not affect functional substitution but may impact procurement and logistics considerations.

Frequently Asked Questions (FAQ)

Q: Can the GBL04 directly replace the TS4K40 D3G in all applications?

A: The GBL04 is a direct substitute only in applications where the circuit design operates at or below 3 A average rectified current. The GBL04 is not suitable for applications requiring the full 4 A capacity of the TS4K40 D3G. Both parts share identical voltage ratings (400 V), temperature ranges (-55°C to 150°C), and package configurations (4-SIP, GBL).

Q: Are there differences in forward voltage drop between these parts?

A: The TS4K40 D3G specifies 1.1 V maximum forward voltage at 4 A, while the GBL04 specifies 1 V maximum at 2 A. These measurements are taken at different current levels and do not directly indicate performance differences at equivalent operating points. Both parts operate within standard rectifier specifications for the 400 V class.

Q: Do both parts have the same package footprint?

A: Yes. Both the TS4K40 D3G and GBL04 use the 4-SIP, GBL package configuration with through-hole mounting. They are mechanically interchangeable on PCBs designed for this package type.

Q: What is the significance of the reverse leakage current specification?

A: Both parts specify 10 µA reverse leakage at 400 V, indicating identical leakage performance. This parameter is critical for applications requiring low standby current and is a key factor in confirming parametric equivalence between these bridge rectifiers.

Q: Are there compliance or environmental differences between these parts?

A: Both parts are RoHS3 compliant and carry MSL Level 1 (Unlimited) ratings. The TS4K40 D3G is REACH Unaffected, while the GBL04 is listed as Vendor Undefined for REACH status. Both parts are suitable for standard industrial applications without environmental restrictions based on moisture sensitivity.

Q: What should determine the choice between TS4K40 D3G and GBL04?

A: Selection should be based on the application's current requirement. If the circuit requires 4 A capacity, the TS4K40 D3G is the appropriate choice. If the circuit operates at 3 A or below, the GBL04 is a valid substitute. Inventory availability and procurement lead times may also influence selection between these active products.
