Key Parameters

Substitute Part Grouping Explanation

Substitution of the ES3BB-13 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 3 A minimum
• Package / Case: DO-214AA, SMB (physical and thermal compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Operating Temperature Range: -55°C to 150°C minimum (thermal envelope)

Performance Characteristics:

• Reverse Recovery Time (trr): Fast recovery ≤ 500 ns or equivalent
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 3 A or lower (efficiency consideration)
• Current - Reverse Leakage @ Vr: 10 µA @ 100 V or lower (leakage specification)

Parts meeting all critical parameters are classified as direct equivalents. Parts meeting voltage, current, and package requirements but with different recovery speed characteristics are classified as functional substitutes with performance trade-offs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ES3BB-13-F

The ES3BB-13-F is a parametric equivalent manufactured by Diodes Incorporated. It matches all electrical specifications of the ES3BB-13, including voltage rating (100 V), current rating (3 A), forward voltage (900 mV @ 3 A), reverse recovery time (25 ns), and operating temperature range (-55°C to 150°C). The ES3BB-13-F is currently in active product status with significantly higher inventory availability (126,199 pieces). The primary distinction is packaging format: ES3BB-13-F is supplied in Tape & Reel (TR) configuration versus bulk packaging for the main part. Additionally, ES3BB-13-F carries ROHS3 compliance, whereas the ES3BB-13 is RoHS non-compliant. For new designs and production applications, ES3BB-13-F is the direct replacement.

Secondary Substitute: S3BB-TP

The S3BB-TP manufactured by Micro Commercial Co meets the voltage (100 V), current (3 A), and package (DO-214AA, SMB) requirements. However, it exhibits performance differences that must be considered:

• Forward voltage is higher at 1.15 V @ 3 A compared to 900 mV @ 3 A, resulting in increased power dissipation
• Recovery speed is standard (>500 ns) rather than fast recovery (≤ 500 ns), affecting switching efficiency in high-frequency applications
• Reverse recovery time is not specified
• Operating temperature range is not specified
• Product status is "Not For New Designs"

The S3BB-TP is suitable only for legacy applications where the higher forward voltage and slower recovery characteristics are acceptable. It is not recommended for new designs.

Compliance Considerations:

For applications requiring RoHS compliance, ES3BB-13-F is the appropriate selection. The original ES3BB-13 is RoHS non-compliant and discontinued. The S3BB-TP is ROHS3 compliant but carries a "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can ES3BB-13-F be used as a direct replacement for ES3BB-13?

A: Yes. ES3BB-13-F is a parametric equivalent with identical electrical specifications: 100 V reverse voltage, 3 A current rating, 900 mV forward voltage @ 3 A, 25 ns reverse recovery time, and -55°C to 150°C operating temperature range. Both use the DO-214AA (SMB) package. The primary difference is packaging format (Tape & Reel versus bulk) and RoHS compliance status. For PCB assembly, ES3BB-13-F is the direct functional replacement.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes have reverse recovery times ≤ 500 ns, while standard recovery diodes exceed 500 ns. The ES3BB-13 and ES3BB-13-F both feature 25 ns reverse recovery time (fast recovery), enabling efficient operation in switching power supplies and high-frequency rectification circuits. The S3BB-TP uses standard recovery characteristics, resulting in slower switching transitions and higher switching losses in high-frequency applications.

Q: Why is the forward voltage of S3BB-TP higher than ES3BB-13?

A: Forward voltage is a material and design characteristic of the diode junction. The S3BB-TP exhibits 1.15 V @ 3 A compared to 900 mV @ 3 A for ES3BB-13. This 250 mV difference results in increased power dissipation (P = Vf × I) and heat generation. In a 3 A application, this represents an additional 750 mW of dissipation, requiring thermal management consideration.

Q: Is S3BB-TP suitable for new product designs?

A: No. S3BB-TP carries a "Not For New Designs" product status designation. This classification indicates the manufacturer does not recommend this part for new applications. For new designs, ES3BB-13-F is the appropriate selection.

Q: What does RoHS compliance mean for this application?

A: RoHS (Restriction of Hazardous Substances) compliance restricts the use of specific hazardous materials including lead, cadmium, and mercury. ES3BB-13-F is ROHS3 compliant, meeting current regulatory requirements for many markets. The original ES3BB-13 is RoHS non-compliant. For applications subject to RoHS regulations, ES3BB-13-F must be selected.

Q: Can I use S3BB-TP in a high-frequency switching application?

A: S3BB-TP is not recommended for high-frequency switching applications. Its standard recovery speed (>500 ns) versus fast recovery (25 ns) results in significantly longer switching transitions, increased switching losses, and potential electromagnetic interference. ES3BB-13-F is the appropriate choice for switching power supplies and high-frequency rectification circuits.

Q: Are there any thermal differences between these parts?

A: The operating temperature range for ES3BB-13 and ES3BB-13-F is -55°C to 150°C. The S3BB-TP operating temperature range is not specified in the provided data. Additionally, the higher forward voltage of S3BB-TP (1.15 V versus 900 mV) generates more heat at rated current, requiring additional thermal management consideration in applications with limited heat dissipation capability.

Q: What is the significance of the DO-214AA (SMB) package?

A: DO-214AA, commonly designated SMB (Surface Mount Body), is a standardized surface mount package for rectifier diodes. All three parts (ES3BB-13, ES3BB-13-F, and S3BB-TP) use this identical package, ensuring mechanical and thermal compatibility on PCBs. The package provides adequate thermal dissipation for 3 A continuous operation and is widely supported by automated assembly equipment.

Q: Why is inventory availability different between these parts?

A: ES3BB-13-F has significantly higher inventory (126,199 pieces) compared to ES3BB-13 (4,160 pieces) and S3BB-TP (3,100 pieces). This reflects ES3BB-13-F's active product status and current market demand. The ES3BB-13 is discontinued, and S3BB-TP is not recommended for new designs, resulting in lower stock levels.
