TS20P02G Bridge Rectifier Diode Equivalent & Substitute Parts

Part Overview

The TS20P02G is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 V peak reverse voltage and 20 A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in AC-to-DC conversion circuits. The part maintains active product status with 886 units in current inventory stock.

Bridge rectifier diodes are essential components in power supply circuits where AC voltage conversion to DC is required. Equivalent and substitute parts become necessary when primary sourcing is unavailable, when alternative supplier relationships are preferred, or when inventory optimization across multiple manufacturers is required.

Substitute Part Grouping Explanation

Substitution of the TS20P02G is determined by strict equivalence across the following critical parameters:

Voltage Rating: Peak reverse voltage must equal 100 V
Current Rating: Average rectified current must equal 20 A
Forward Voltage Drop: Maximum forward voltage must equal 1.1 V at 20 A
Reverse Leakage: Maximum reverse leakage current must not exceed 10 µA at the specified reverse voltage
Operating Temperature Range: Must support -55°C to 150°C junction temperature
Diode Configuration: Single-phase bridge rectifier topology
Mounting Technology: Through-hole mounting only
Package Form Factor: 4-SIP, TS-6P package designation

The DFB2010 manufactured by Fairchild Semiconductor meets all critical electrical and mechanical parameters required for direct substitution with the TS20P02G.

This part is ROHS3 compliant, REACH unaffected, and carries MSL Level 1 (unlimited moisture sensitivity rating). Selection of the TS20P02G is appropriate when Taiwan Semiconductor supply chain relationships are established or when inventory from this manufacturer is preferred.

DFB2010 (Fairchild Semiconductor)

The DFB2010 is a parametric equivalent substitute with confirmed inventory of 1,935 units. This part meets all critical electrical specifications and maintains identical package form factor and mounting technology. The DFB2010 is classified under identical ECCN and HTSUS codes, confirming regulatory equivalence. Selection of the DFB2010 is appropriate when Fairchild Semiconductor supply relationships are active, when higher inventory availability is required, or when alternative sourcing is necessary due to primary supplier constraints.

Both parts are active products suitable for new design implementation and production deployment.

Frequently Asked Questions (FAQ)

Q: Can the DFB2010 be used as a direct replacement for the TS20P02G in existing circuit designs?

A: Yes. The DFB2010 meets all critical electrical parameters including voltage rating (100 V), current rating (20 A), forward voltage drop (1.1 V @ 20 A), and operating temperature range (-55°C to 150°C). Both components use identical 4-SIP, TS-6P package form factor and through-hole mounting technology, enabling direct PCB substitution without circuit modification.

Q: Are there differences in reverse leakage current specifications between these parts?

A: The TS20P02G specifies 10 µA reverse leakage at 100 V, while the DFB2010 specifies 10 µA reverse leakage at 50 V. Both specifications meet the 10 µA maximum leakage requirement. The DFB2010 specification is measured at lower reverse voltage, indicating equivalent or superior leakage performance at the TS20P02G operating condition.

Q: Do both parts require identical PCB footprints?

A: Yes. Both the TS20P02G and DFB2010 use the 4-SIP, TS-6P package designation with through-hole mounting. PCB footprints, lead spacing, and mounting hole requirements are identical. No PCB layout modifications are required when substituting between these parts.

Q: What is the inventory status for each part?

A: The TS20P02G has 886 units in current stock. The DFB2010 has 1,935 units in current stock. Higher inventory availability of the DFB2010 may support extended production runs or expedited delivery requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TS20P02G and DFB2010 are classified under identical ECCN (EAR99) and HTSUS (8541.10.0080) codes. The TS20P02G carries ROHS3 compliance and REACH unaffected status. Both parts are suitable for applications requiring regulatory compliance in current manufacturing environments.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts support identical operating temperature range of -55°C to 150°C junction temperature. Thermal performance and reliability are equivalent across the full operating range.
