Current - Average Rectified (Io): 2 A
Mounting Type: Through Hole
Package / Case: DO-204AC, DO-15, or Axial configurations
Operating Temperature - Junction: Minimum -55°C to 150°C (RL207-T operates to -65°C)
RoHS3 Compliance: Required

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: Acceptable range 1.0 V to 2.2 V @ 2 A
Current - Reverse Leakage @ Vr: Acceptable range 1 µA to 10 µA @ 1000 V

Engineering Selection Recommendations

Direct Package Equivalents (Recommended for Pin-Compatible Replacement):

The 2A07G B0G (Taiwan Semiconductor Corporation) provides the closest electrical match to the RL207-T with identical voltage, current, and forward voltage specifications. This part is active and available in high inventory (1039 pcs), making it the primary substitute for direct PCB replacement in DO-204AC (DO-15) footprints.

The GPP20M-E3/54 and GPP20M-E3/73 (Vishay General Semiconductor - Diodes Division) are functionally equivalent with marginally higher forward voltage (1.1 V vs. 1 V) and are available in high quantities (42,558 and 55,400 pcs respectively). Both maintain standard recovery characteristics and full compliance with RoHS3 and REACH requirements.

Fast Recovery Alternatives (For Switching Applications):

The HER208G-AP and HER208G-TP (Micro Commercial Co) offer fast recovery characteristics (≤500ns) with identical voltage and current ratings. These parts are suitable for applications requiring reduced reverse recovery time. The HER208G-TP variant is available in higher inventory (29,729 pcs) and is packaged in cut tape format.

Alternative Package Form (For Axial Lead Applications):

The MUR2100EG and MUR2100ERLG (onsemi) provide equivalent electrical performance in DO-41 axial package format. These parts feature fast recovery (≤500ns) and extended temperature range (-65°C to 175°C), matching the RL207-T lower temperature limit. The MUR2100ERLG variant is available in significantly higher inventory (55,100 pcs) and is supplied in cut tape format.

Avalanche Technology Option:

The BYW56-TR (Vishay General Semiconductor - Diodes Division) is an avalanche-rated diode with identical voltage and current specifications but in SOD-57 package. This part features superior reverse leakage performance (1 µA vs. 5 µA) and extended temperature range (-55°C to 175°C). Avalanche technology provides enhanced transient overvoltage protection, making this suitable for applications with voltage spike concerns.

All recommended substitutes comply with RoHS3 and REACH regulations and are classified as active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 2A07G B0G directly replace the RL207-T without PCB modification?

A: Yes. The 2A07G B0G is packaged in DO-204AC (DO-15), which is mechanically and electrically compatible with the RL207-T DO-15 package. No PCB layout changes are required for direct substitution.

Q: What is the difference between the GPP20M-E3/54 and GPP20M-E3/73 variants?

A: Both parts are electrically identical with 1000 V, 2 A ratings and standard recovery characteristics. The designation suffix indicates different tape reel configurations for automated assembly. Selection depends on procurement and assembly equipment compatibility.

Q: Why do the MUR2100EG and MUR2100ERLG have higher forward voltage (2.2 V) compared to the RL207-T (1 V)?

A: The MUR2100 series features fast recovery technology (100 ns reverse recovery time), which inherently results in higher forward voltage drop. This trade-off is acceptable in switching applications where reduced reverse recovery time improves efficiency and reduces EMI.

Q: Is the BYW56-TR suitable for all applications where the RL207-T was used?

A: The BYW56-TR is electrically compatible with identical voltage and current ratings. However, it uses avalanche technology and is packaged in SOD-57 format instead of DO-15. PCB layout modification is required for package change. Avalanche technology provides additional transient overvoltage protection, making it suitable for harsh electrical environments.

Q: What is the temperature range limitation when substituting the RL207-T?

A: The RL207-T operates from -65°C to 150°C. Most substitute parts (2A07G B0G, GPP20M-E3/54, GPP20M-E3/73, HER208G-AP, HER208G-TP) operate from -55°C to 150°C, reducing the lower temperature limit by 10°C. The MUR2100EG and MUR2100ERLG maintain the -65°C lower limit. Verify application requirements before selection.

Q: Are all substitute parts RoHS3 and REACH compliant?

A: Yes. All recommended substitute parts listed are RoHS3 compliant and REACH unaffected, matching the environmental compliance status of the RL207-T.

Q: What is the difference between cut tape (CT) and bulk packaging options?

A: Cut tape (CT) packaging is supplied on continuous tape suitable for automated pick-and-place assembly. Bulk packaging is supplied loose in containers for manual assembly or reel winding. Selection depends on assembly process requirements and equipment compatibility.

Q: Can the HER208G series be used as a direct replacement in all circuits?

A: The HER208G series (HER208G-AP, HER208G-TP) features fast recovery (≤500ns, 75 ns trr) compared to the RL207-T standard recovery (>500ns). Fast recovery reduces switching losses and EMI in high-frequency applications. However, higher forward voltage (1.7 V vs. 1 V) increases power dissipation. Verify thermal and efficiency requirements before substitution.

Q: What inventory levels should be considered for long-term supply assurance?

A: The GPP20M-E3/73 (55,400 pcs), MUR2100ERLG (55,100 pcs), and HER208G-TP (29,729 pcs) offer the highest inventory levels, providing superior supply continuity. The 2A07G B0G (1,039 pcs) and HER208G-AP (1,176 pcs) have lower inventory and may require longer lead times for large volume orders.
