ES3HB Equivalent & Substitute Parts

Part Overview

The ES3HB is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 500V DC reverse voltage and 3A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds, suitable for standard rectification applications requiring moderate voltage and current ratings.

The ES3HB maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Identification of equivalent and substitute parts becomes necessary when the primary part number is unavailable from inventory or when alternative packaging formats are required for manufacturing flexibility.

Substitute Part Grouping Explanation

Substitution of the ES3HB is determined by strict equivalence across all critical electrical parameters. The substitute part ES3HB R5G maintains identical electrical specifications including reverse voltage rating, average rectified current, forward voltage drop, reverse recovery time, reverse leakage current, and junction capacitance. Both parts utilize the same semiconductor technology classification (Standard) and package type (DO-214AA/SMB).

The primary distinction between the main part and its substitute is the packaging format: the ES3HB is supplied in Tape & Reel (TR) configuration, while the ES3HB R5G is supplied in Cut Tape (CT) configuration. Both packaging formats are compatible with automated assembly equipment and represent different supply chain options rather than functional differences.

Key Parameters Determining Substitution:

• Voltage - DC Reverse (Vr) (Max): 500 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.45 V @ 3 A
• Reverse Recovery Time (trr): 35 ns
• Package / Case: DO-214AA (SMB)
• Mounting Type: Surface Mount

Parameter Comparison

Engineering Selection Recommendations

The ES3HB R5G serves as a direct parametric equivalent to the ES3HB for all electrical and thermal specifications. Both parts are manufactured by Taiwan Semiconductor Corporation and carry identical RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment in applications requiring environmental compliance documentation.

Selection between these parts should be based on packaging requirements and supply chain availability. The ES3HB in Tape & Reel format is suitable for high-volume automated assembly operations utilizing standard pick-and-place equipment with reel feeders. The ES3HB R5G in Cut Tape format accommodates lower-volume production runs or manual assembly processes where individual component handling is required.

The ES3HB maintains Active product status, indicating ongoing manufacturer support and availability. The ES3HB R5G is noted as discontinued at DiGi Electronics, which may affect long-term supply reliability through certain distribution channels. For new designs or long-term production commitments, the ES3HB (Active status) is the preferred selection. The ES3HB R5G remains suitable for applications where existing inventory is available or where alternative distribution sources maintain stock.

Both parts satisfy identical electrical performance requirements for 500V, 3A rectification applications with fast recovery characteristics. No functional performance difference exists between these parts when applied within their specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the ES3HB R5G be used as a direct replacement for the ES3HB in production assembly?

A: Yes. The ES3HB R5G is electrically and mechanically identical to the ES3HB. The only difference is the packaging format (Cut Tape versus Tape & Reel). Both parts use the same DO-214AA (SMB) surface mount package and are compatible with standard pick-and-place assembly equipment. Packaging format selection depends on production volume and feeder compatibility rather than functional performance.

Q: What are the critical parameters that define substitution eligibility for the ES3HB?

A: Substitution eligibility is determined by matching the following parameters: Voltage - DC Reverse (Vr) Maximum of 500V, Current - Average Rectified (Io) of 3A, Voltage - Forward (Vf) Maximum of 1.45V @ 3A, Reverse Recovery Time of 35 nanoseconds, and the DO-214AA (SMB) surface mount package. Any deviation in these parameters disqualifies a part from serving as a substitute.

Q: Are there compliance or regulatory differences between the ES3HB and ES3HB R5G?

A: No. Both parts carry identical RoHS3 compliance certification, REACH unaffected status, and unlimited moisture sensitivity level (MSL 1). Regulatory documentation and environmental compliance requirements are satisfied equally by either part.

Q: What is the significance of the product status difference between these parts?

A: The ES3HB maintains Active product status, indicating ongoing manufacturer support, continued production, and reliable long-term availability. The ES3HB R5G is discontinued at DiGi Electronics, which may limit availability through certain distribution channels. For new designs or applications requiring long-term supply assurance, the ES3HB is the preferred selection. However, the ES3HB R5G remains functionally suitable if inventory is available through alternative sources.

Q: Can these parts be mixed within the same production batch?

A: Yes. Since the ES3HB and ES3HB R5G are electrically and mechanically identical, they can be used interchangeably within the same circuit design and production batch. The packaging format difference does not affect circuit performance or reliability. However, assembly equipment configuration may require adjustment when switching between Tape & Reel and Cut Tape formats.

Q: What is the operating temperature range for both parts?

A: Both the ES3HB and ES3HB R5G operate across a junction temperature range of -55°C to 150°C. This range applies to both parts identically and determines the maximum ambient operating conditions when thermal management is considered.

Q: Are there any differences in reverse recovery characteristics between these parts?

A: No. Both parts exhibit identical reverse recovery time of 35 nanoseconds and identical reverse leakage current of 10 microamperes at 500V. These fast recovery characteristics are maintained across both part numbers.
