ES3DPX Equivalent & Substitute Parts

Part Overview

The ES3DPX is a general-purpose rectifier diode manufactured by Nexperia USA Inc., rated for 200 V DC reverse voltage and 3 A average rectified current in a surface mount SOD-128/CFP5 package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part operates with fast recovery characteristics suitable for standard rectification applications requiring moderate voltage and current ratings.

Substitute Part Grouping Explanation

Substitution of the ES3DPX is determined by matching the following critical electrical and mechanical parameters:

Electrical Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 3 A minimum
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Forward voltage characteristics within acceptable operating range

Mechanical Matching Criteria:

Mounting Type: Surface Mount
Package / Case: SOD-128 or equivalent footprint compatibility
Operating Temperature - Junction: 150°C maximum

Compliance Matching Criteria:

RoHS3 Compliance required

Engineering Selection Recommendations

The CMH01(TE12L,Q,M) from Toshiba Semiconductor and Storage is a direct functional equivalent for the obsolete ES3DPX. Selection of this substitute is supported by the following factors:

Electrical Equivalence: Both devices maintain identical voltage and current ratings (200 V, 3 A) with matching fast recovery speed classification. Forward voltage characteristics are compatible across the specified operating range.

Mechanical Compatibility: Both components utilize SOD-128 surface mount packaging, ensuring PCB footprint compatibility without layout modification.

Compliance Status: The CMH01(TE12L,Q,M) maintains ROHS3 compliance and MSL 1 rating, matching the environmental and regulatory requirements of the original ES3DPX.

Product Availability: The CMH01(TE12L,Q,M) carries Active product status with documented inventory availability, providing supply chain continuity for applications currently using the obsolete ES3DPX.

Reverse Recovery Time Consideration: The CMH01(TE12L,Q,M) exhibits a reverse recovery time of 100 ns compared to 25 ns for the ES3DPX. This parameter difference remains within fast recovery classification limits and does not affect functional substitution for standard rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the CMH01(TE12L,Q,M) directly replace the ES3DPX without PCB modifications?

A: Yes. Both devices share identical SOD-128 surface mount packaging and footprint specifications, enabling direct replacement without PCB layout changes.

Q: Are the electrical ratings identical between ES3DPX and CMH01(TE12L,Q,M)?

A: Voltage and current ratings are identical (200 V, 3 A). Forward voltage characteristics are compatible. Reverse recovery time differs (25 ns vs. 100 ns) but both devices meet fast recovery speed classification requirements.

Q: What is the significance of the reverse recovery time difference?

A: Reverse recovery time affects switching transient behavior in high-frequency applications. The CMH01(TE12L,Q,M) at 100 ns remains within fast recovery classification and is suitable for standard rectification applications. Applications requiring sub-50 ns recovery times should evaluate specific circuit requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ES3DPX and CMH01(TE12L,Q,M) carry ROHS3 Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the ES3DPX classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Nexperia USA Inc. The CMH01(TE12L,Q,M) maintains Active product status with ongoing manufacturing support.

Q: Are there any package variant considerations?

A: The ES3DPX uses SOD-128/CFP5 supplier packaging. The CMH01(TE12L,Q,M) uses M-FLAT (2.4x3.8) supplier packaging. Both conform to SOD-128 standard footprint specifications for surface mount assembly.

Q: What compliance certifications apply to both parts?

A: Both devices carry ROHS3 Compliant status, EAR99 ECCN classification, and HTSUS 8541.10.0080 tariff code. MSL rating is 1 (Unlimited) for both parts.
