Equivalent & Substitute Parts for ESH1DM

Part Overview

ESH1DM is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation, specified for 1A average rectified current and a maximum reverse voltage of 200V. The component features a surface mount Micro SMA package and is RoHS3 compliant with an operating junction temperature range of -55°C to 150°C. The device is active in the manufacturer’s catalog. Substitution may be necessary for reasons such as supply chain constraints, inventory optimization, or multi-sourcing strategies within the category of diodes and rectifiers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for diodes and rectifiers such as ESH1DM are selected strictly based on alignment of key electrical and mechanical parameters, including:

• Maximum reverse voltage (Vr)
• Average rectified current (Io)
• Maximum forward voltage drop (Vf) at rated current
• Reverse recovery time (trr)
• Reverse leakage current at maximum Vr
• Package type and mounting method
• Compliance with RoHS and REACH regulations
  These criteria ensure that functional, mechanical, and regulatory interchangeability is maintained.

Parameter Comparison

Engineering Selection Recommendations

Both ESH1DM and RF05VAM2STR have active product status and are RoHS3 compliant, with MSL ratings of 1 (unlimited shelf life) and REACH unaffected classification. They are classified under ECCN EAR99. The manufacturer's stated compliance and certifications support selection for projects requiring environmental or export compliance based on the stated parameters.

Frequently Asked Questions (FAQ)

Q1: What are the essential electrical parameters when selecting a substitute diode for ESH1DM?
A1: Key parameters include maximum DC reverse voltage, average rectified current, maximum forward voltage drop at rated current, reverse recovery time, and reverse leakage current at maximum reverse voltage.

Q2: Are different package names (Micro SMA vs. TUMD2S) acceptable for substitution?
A2: Acceptability is strictly determined by package outline and lead form. Both ESH1DM and RF05VAM2STR are surface-mount 2-SMD, flat lead types, which align mechanically.

Q3: Do both ESH1DM and RF05VAM2STR comply with RoHS and REACH regulations?
A3: Both diodes are RoHS3 compliant and REACH unaffected as stated in the manufacturer parameters.

Q4: How is product status relevant to the selection of substitute rectifier diodes?
A4: Active product status ensures that the part is currently in production and available for procurement.

Q5: If the average rectified current ratings differ, can substitution be made?
A5: Only substitutions with matching or suitably rated average current as specified should be used; the maximum average rectified current must be checked against system requirements.
