RL106F General Purpose Rectifier Diode – Equivalent & Substitute Parts

Part Overview

The RL106F is an active general purpose rectifier diode manufactured by SMC Diode Solutions, rated for 800 V DC reverse voltage and 1 A average rectified current. This through-hole axial diode is designed for standard rectification applications requiring fast recovery characteristics. The part is RoHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide alternative sourcing options when the primary RL106F is unavailable or when inventory constraints require component alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the RL106F are qualified based on the following electrical and mechanical parameters:

Matching Criteria:

Voltage – DC Reverse (Vr) Maximum: 800 V
Mounting Type: Through Hole
Package / Case: Axial
Technology: Standard rectifier diode
Fast Recovery characteristic (trr ≤ 500 ns, > 200 mA)

Allowable Variations:

Current – Average Rectified (Io): Substitute parts rated at 500 mA or higher are acceptable for applications where the RL106F's 1 A rating is specified, provided circuit design accommodates the lower current rating
Voltage – Forward (Vf): Variations within the fast recovery diode class are acceptable
Reverse Recovery Time (trr): Faster recovery times (lower trr values) are acceptable
Operating Temperature Range: Narrower ranges are acceptable if minimum and maximum bounds encompass the application requirements

Engineering Selection Recommendations

RL106F Selection: The RL106F is the primary choice for applications requiring 1 A average rectified current at 800 V reverse voltage with fast recovery characteristics. This part is RoHS3 compliant and rated for extended low-temperature operation (–65°C junction). Use this part when full 1 A current capacity and extended temperature range are required.

AB01BV1 Selection: The AB01BV1 is a substitute option for applications where average rectified current does not exceed 500 mA at 800 V reverse voltage. This part is RoHS compliant and offers faster reverse recovery time (200 ns versus 500 ns). The operating temperature range is limited to –40°C minimum. Use this part only when circuit design accommodates the 500 mA current limitation and minimum junction temperature of –40°C is acceptable.

Both parts are active products with current inventory availability and carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can AB01BV1 directly replace RL106F in all applications?

A: No. The AB01BV1 is rated for 500 mA average rectified current, while the RL106F is rated for 1 A. Direct substitution is only valid for circuits designed for 500 mA or lower current operation. Circuit analysis is required to confirm current requirements do not exceed 500 mA.

Q: What is the impact of the different reverse recovery times?

A: The AB01BV1 has a reverse recovery time of 200 ns compared to the RL106F's 500 ns. Faster recovery reduces switching losses and electromagnetic interference in high-frequency applications. Both parts meet the fast recovery classification (≤ 500 ns, > 200 mA).

Q: Are there temperature range limitations with AB01BV1?

A: Yes. The AB01BV1 operating temperature range is –40°C to 150°C junction temperature, while the RL106F extends to –65°C minimum. Applications requiring operation below –40°C junction temperature must use the RL106F.

Q: Do both parts have identical packaging?

A: Both parts use through-hole axial package configuration. The RL106F is supplied in Tape & Box (TB) packaging, while the AB01BV1 is supplied in Cut Tape (CT) packaging. Physical dimensions and lead spacing are identical for PCB mounting compatibility.

Q: What is the difference in forward voltage drop?

A: The RL106F specifies 1.3 V maximum forward voltage at 1 A, while the AB01BV1 specifies 2 V maximum at 500 mA. These measurements are taken at different current levels and cannot be directly compared. Forward voltage characteristics depend on operating current.

Q: Are both parts RoHS compliant?

A: Yes. The RL106F is RoHS3 compliant, and the AB01BV1 is RoHS compliant. Both parts meet lead-free and hazardous substance restrictions for electronic components.

Q: What is the reverse leakage current difference?

A: The RL106F has 5 µA reverse leakage at 800 V, while the AB01BV1 has 10 µA at 800 V. The AB01BV1 exhibits twice the reverse leakage current. For applications sensitive to leakage current, the RL106F is the preferred choice.
