ES1DLHMHG Equivalent & Substitute Parts

Part Overview

The ES1DLHMHG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 1 A average rectified current. This surface mount component operates in the fast recovery category with a reverse recovery time of 35 nanoseconds. The part is classified as Active product status and carries automotive-grade qualification under AEC-Q101 standards.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range. The ES1DLHMHG serves as the primary reference for this equivalency group, with alternative part numbers available to support supply chain flexibility and inventory optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the ES1DLHMHG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
Package / Case: DO-219AB (Sub SMA)
Mounting Type: Surface Mount
Operating Temperature - Junction: -55°C to 150°C
Technology: Standard
RoHS Status: ROHS3 Compliant

Allowable Parameter Variation: Reverse recovery time (trr) and capacitance (Cj) may vary within the fast recovery classification (≤500 ns for currents >200 mA). These parameters do not disqualify substitution when all mandatory criteria are met.

The identified substitute parts ES1DL and HS1DL RVG maintain full electrical and mechanical compatibility with the ES1DLHMHG across all mandatory parameters while operating within the same automotive-grade qualification framework.

Engineering Selection Recommendations

ES1DL Selection Criteria: The ES1DL is a parametric equivalent to the ES1DLHMHG with identical electrical specifications across all critical parameters. Both parts maintain 35 nanosecond reverse recovery time and 10 pF capacitance. The ES1DL is available in Cut Tape (CT) and Digi-Reel® packaging formats, offering supply chain flexibility. Both parts carry Active product status and ROHS3 compliance. The ES1DL represents a direct functional replacement with no performance trade-offs.

HS1DL RVG Selection Criteria: The HS1DL RVG maintains equivalence across mandatory electrical parameters including 200 V reverse voltage, 1 A current rating, and 950 mV forward voltage. This part operates within the fast recovery classification with a 50 nanosecond reverse recovery time, which is within the allowable ≤500 ns specification. The capacitance specification of 20 pF represents a measurable increase from the 10 pF baseline but remains within acceptable operating parameters for general-purpose rectification applications. The HS1DL RVG is available in Cut Tape (CT) packaging. Both parts carry Active product status and ROHS3 compliance.

Compliance and Certification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). The ES1DLHMHG carries explicit automotive-grade qualification under AEC-Q101. Applications requiring automotive-grade certification should prioritize the ES1DLHMHG or confirm HS1DL RVG and ES1DL automotive applicability through design documentation.

Frequently Asked Questions (FAQ)

Q: Can ES1DL be used as a direct replacement for ES1DLHMHG?

A: Yes. The ES1DL maintains identical electrical specifications across all critical parameters: 200 V reverse voltage, 1 A current rating, 950 mV forward voltage, 35 ns reverse recovery time, and 10 pF capacitance. Both parts use the DO-219AB Sub SMA package and surface mount technology. The primary difference is packaging format (Cut Tape and Digi-Reel® for ES1DL versus standard packaging for ES1DLHMHG).

Q: What are the differences between HS1DL RVG and ES1DLHMHG?

A: The HS1DL RVG differs in two parameters: reverse recovery time (50 ns versus 35 ns) and capacitance (20 pF versus 10 pF). Both differences fall within the fast recovery classification and do not affect core electrical equivalence. The 50 ns recovery time remains well below the 500 ns fast recovery threshold. The 20 pF capacitance increase is measurable but acceptable for general-purpose rectification. Both parts maintain identical voltage, current, and temperature specifications.

Q: Are all three parts suitable for automotive applications?

A: The ES1DLHMHG carries explicit AEC-Q101 automotive-grade qualification. The ES1DL and HS1DL RVG do not list automotive-grade qualification in the provided specifications. Applications requiring automotive-grade certification should use the ES1DLHMHG or obtain automotive qualification documentation for ES1DL and HS1DL RVG from the manufacturer.

Q: What packaging formats are available for each part?

A: ES1DLHMHG is supplied in standard packaging. ES1DL is available in Cut Tape (CT) and Digi-Reel® formats. HS1DL RVG is available in Cut Tape (CT) format. All three parts use the DO-219AB Sub SMA package case.

Q: Do all parts meet RoHS and REACH compliance requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the inventory status for each part?

A: ES1DLHMHG has 681 pieces in stock. ES1DL has 9534 pieces in stock. HS1DL RVG has 2820 pieces in stock. All parts are listed as New Original In Stock.

Q: Can reverse recovery time differences affect circuit performance?

A: Reverse recovery time (trr) affects switching speed and switching losses in high-frequency applications. The ES1DLHMHG and ES1DL both specify 35 ns, while HS1DL RVG specifies 50 ns. For general-purpose rectification at standard line frequencies, this 15 ns difference is not significant. High-frequency switching applications should use parts with matching trr specifications.

Q: Are there any restrictions on operating temperature?

A: All three parts operate across the identical junction temperature range of -55°C to 150°C. No temperature-based restrictions apply to substitution.
