ES3JB-13-F Equivalent & Substitute Parts

Part Overview

The ES3JB-13-F is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 600 V DC reverse voltage and 3 A average rectified current in a Surface Mount SMB (DO-214AA) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution of the ES3JB-13-F with the RS3JB-HF is based on matching the following critical electrical and mechanical parameters:

Voltage Rating: Both parts are rated for 600 V DC reverse voltage maximum
Current Rating: Both parts support 3 A average rectified current
Forward Voltage: Both parts specify 1.3 V maximum forward voltage at 3 A
Speed Classification: Both parts are classified as Fast Recovery with recovery time ≤ 500 ns for currents > 200 mA
Package Compatibility: Both parts use the DO-214AA SMB surface mount package
Mounting Type: Both are surface mount components
Temperature Range: Both operate across -55°C to 150°C junction temperature
Compliance: Both are RoHS3 compliant and have identical ECCN and HTSUS classifications

The RS3JB-HF manufactured by Comchip Technology meets all substitution criteria for applications requiring a 600 V, 3 A general-purpose rectifier diode in SMB packaging.

Engineering Selection Recommendations

Both the ES3JB-13-F and RS3JB-HF are Active product status components with full RoHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.10.0080). Selection between these parts is based on availability and supply chain requirements rather than electrical performance differences.

The ES3JB-13-F offers a faster reverse recovery time of 35 ns compared to the RS3JB-HF at 250 ns. Both values remain within the Fast Recovery specification (≤ 500 ns). The RS3JB-HF demonstrates lower reverse leakage current (5 µA versus 10 µA at 600 V), which may provide marginal advantages in high-impedance or low-leakage applications.

For standard general-purpose rectification applications operating within the specified voltage and current parameters, either component provides equivalent functional performance. Component selection should prioritize inventory availability and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can the RS3JB-HF directly replace the ES3JB-13-F in existing designs?

A: Yes. Both components share identical voltage ratings (600 V), current ratings (3 A), forward voltage characteristics (1.3 V @ 3 A), and package specifications (DO-214AA SMB). No circuit modifications are required for direct substitution.

Q: What is the difference in reverse recovery time between these parts?

A: The ES3JB-13-F specifies 35 ns reverse recovery time, while the RS3JB-HF specifies 250 ns. Both values satisfy the Fast Recovery classification (≤ 500 ns for currents > 200 mA). The faster recovery time of the ES3JB-13-F may provide marginal switching performance benefits in high-frequency applications, but both parts are functionally equivalent for standard rectification.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both the ES3JB-13-F and RS3JB-HF use the DO-214AA SMB surface mount package. PCB footprints, solder pad layouts, and mounting procedures are identical. No board redesign is necessary.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both components are RoHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8541.10.0080) codes. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Which part should be selected for low-leakage applications?

A: The RS3JB-HF demonstrates lower reverse leakage current at 5 µA compared to the ES3JB-13-F at 10 µA (both measured at 600 V). For applications where leakage current is a design constraint, the RS3JB-HF is the preferred selection.

Q: Are there temperature operating range differences?

A: No. Both parts operate across the identical junction temperature range of -55°C to 150°C.
