ES5GC-HF General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The ES5GC-HF is an active general purpose rectifier diode manufactured by Comchip Technology, rated for 400 V DC reverse voltage and 5 A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for standard rectification applications requiring fast recovery characteristics and operates across a junction temperature range of -55°C to 150°C.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources for this diode are necessary to support supply chain flexibility, inventory availability, and design continuity in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ES5GC-HF are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 5 A
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 5 A
• Reverse Recovery Time (trr): 35 ns
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

The identified substitute parts ER5G and ES5GC maintain equivalence across all critical electrical ratings and mechanical specifications. Minor variations in reverse leakage current and capacitance do not affect functional substitution within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All three diodes—ES5GC-HF, ER5G, and ES5GC—are active products with ROHS3 compliance and identical core electrical specifications. Selection between these parts is determined by availability, supply chain requirements, and manufacturer preference.

ES5GC-HF (Comchip Technology): Primary specification. Current inventory: 729 pcs. Suitable for applications requiring the original design specification.

ER5G (SMC Diode Solutions): Parametric equivalent with identical electrical performance. Current inventory: 112,043 pcs. REACH Affected status applies. Higher inventory availability supports extended production runs.

ES5GC (MDD): Parametric equivalent with reverse leakage current of 10 µA (versus 5 µA for ES5GC-HF and ER5G). Current inventory: 72,978 pcs. REACH Unaffected status applies. Capacitance specification not provided. Suitable for applications where reverse leakage tolerance permits the higher specification.

All three parts are surface mount components in DO-214AB (SMC) packaging with identical thermal and voltage ratings. Direct substitution is supported without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can ER5G replace ES5GC-HF in existing designs?

A: Yes. ER5G maintains identical electrical specifications across voltage rating (400 V), current rating (5 A), forward voltage drop (1.25 V @ 5 A), and reverse recovery time (35 ns). Both components use the same DO-214AB (SMC) surface mount package. No circuit modification is required.

Q: What is the difference between ES5GC-HF and ES5GC from MDD?

A: Both parts share identical voltage, current, and recovery time specifications. The MDD ES5GC specifies reverse leakage current of 10 µA at 400 V, compared to 5 µA for the Comchip ES5GC-HF. Capacitance is not specified for the MDD part. Selection depends on application leakage current tolerance and available inventory.

Q: Are all three diodes compatible with the same PCB footprint?

A: Yes. All three parts use the DO-214AB (SMC) surface mount package with identical mechanical dimensions and pin configuration. PCB layout and reflow soldering parameters remain unchanged.

Q: Do these diodes have different RoHS compliance status?

A: All three parts are ROHS3 compliant. ER5G is REACH Affected; ES5GC (MDD) is REACH Unaffected. ES5GC-HF REACH status is not specified in the provided data. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: What is the moisture sensitivity level for these diodes?

A: ES5GC-HF specifies MSL 1 (Unlimited). Equivalent MSL data for ER5G and ES5GC (MDD) is not provided in the available specifications. Contact the respective manufacturers for complete moisture sensitivity documentation if required for your assembly process.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: Yes. All three diodes are classified as Fast Recovery with reverse recovery time of 35 ns, supporting switching frequencies typical of standard rectification circuits. The identical trr specification ensures equivalent performance in fast recovery applications.

Q: What packaging formats are available for these parts?

A: All three diodes are supplied in Tape & Reel (TR) format for automated assembly. Reel specifications and tape pitch should be confirmed with the respective manufacturer or distributor for your specific assembly equipment.
