ES3C-13 Equivalent & Substitute Parts

Part Overview

The ES3C-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 150 V DC reverse voltage and 3 A average rectified current in a Surface Mount SMC (DO-214AB) package. This component is classified as discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and production needs. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with compatible or enhanced ratings.

Substitute Part Grouping Explanation

Substitution of the ES3C-13 is determined by the following critical parameters: Voltage - DC Reverse (Vr) rating, Current - Average Rectified (Io) rating, forward voltage drop (Vf), reverse recovery time (trr), package type (DO-214AB, SMC), and mounting configuration (Surface Mount). Parts are grouped into two categories:

Parametric Equivalents maintain all electrical specifications within the same tolerance band and are interchangeable without circuit modification:

ES3C-13-F (Diodes Incorporated)
ES3C-E3/57T (Vishay General Semiconductor - Diodes Division)
ES3C (Taiwan Semiconductor Corporation)

Functional Substitutes provide equal or enhanced electrical performance with compatible package and mounting specifications:

STTH302S (STMicroelectronics) - higher voltage rating (200 V) with equivalent current capacity

All substitute parts maintain the DO-214AB (SMC) package format and Surface Mount configuration required for direct PCB replacement.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

ES3C-13-F is the primary equivalent, manufactured by Diodes Incorporated with identical electrical specifications and active product status. This part is available in Tape & Reel packaging with ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new production.

For Parametric Equivalence with Minor Variations:

ES3C-E3/57T (Vishay) and ES3C (Taiwan Semiconductor Corporation) provide functional equivalence with acceptable parameter variations. ES3C-E3/57T exhibits a 5 ns increase in reverse recovery time (30 ns vs. 25 ns). The ES3C part shows a 50 mV increase in forward voltage drop (950 mV vs. 900 mV) and 10 ns increase in reverse recovery time (35 ns vs. 25 ns). Both parts maintain the 150 V / 3 A rating and are ROHS3 compliant.

For Enhanced Voltage Rating:

STTH302S (STMicroelectronics) provides a 200 V DC reverse voltage rating with equivalent 3 A current capacity. This part is suitable for applications requiring higher voltage margin or operating in elevated voltage environments. Forward voltage drop increases to 950 mV and reverse recovery time extends to 35 ns. Reverse leakage current improves to 3 µA at 200 V.

All substitute parts maintain Surface Mount configuration in DO-214AB (SMC) package format, enabling direct PCB placement without mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can ES3C-13-F be used as a direct replacement for ES3C-13?

A: Yes. ES3C-13-F is a parametric equivalent manufactured by Diodes Incorporated with identical electrical specifications: 150 V reverse voltage, 3 A average rectified current, 900 mV forward voltage drop at 3 A, and 25 ns reverse recovery time. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and active product status with ROHS3 compliance.

Q: What are the differences between ES3C-13 and ES3C (Taiwan Semiconductor Corporation)?

A: Both parts maintain 150 V reverse voltage and 3 A current ratings with identical package configuration. The ES3C part exhibits a 50 mV higher forward voltage drop (950 mV vs. 900 mV at 3 A) and 10 ns longer reverse recovery time (35 ns vs. 25 ns). These variations remain within acceptable operating margins for most general-purpose rectification applications.

Q: Is STTH302S suitable for ES3C-13 replacement?

A: STTH302S is a functional substitute with enhanced voltage rating (200 V vs. 150 V) and equivalent 3 A current capacity. Forward voltage drop increases to 950 mV and reverse recovery time extends to 35 ns. This part is suitable for applications where higher voltage margin is required or beneficial. The DO-214AB (SMC) package enables direct PCB replacement.

Q: What is the significance of the packaging difference between Cut Tape (CT) and Tape & Reel (TR)?

A: Cut Tape and Tape & Reel represent different supply formats for the same component. Cut Tape is supplied in individual strips, while Tape & Reel is supplied on continuous reels for automated assembly. Electrical and mechanical specifications remain identical. Selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: ES3C-13-F, ES3C-E3/57T, ES3C (Taiwan Semiconductor Corporation), and STTH302S are all ROHS3 compliant. The original ES3C-13 is RoHS non-compliant. For applications requiring regulatory compliance, use only the compliant alternatives listed.

Q: What is the reverse recovery time significance in substitute selection?

A: Reverse recovery time (trr) affects switching speed and switching losses in rectification circuits. ES3C-13 specifies 25 ns. ES3C-E3/57T extends this to 30 ns, while ES3C and STTH302S extend to 35 ns. For high-frequency switching applications, shorter recovery times reduce switching losses. For standard rectification, these variations are typically acceptable.

Q: Can ES3C-13 be replaced with STTH302S in all applications?

A: STTH302S provides functional substitution with higher voltage rating (200 V vs. 150 V). The increased forward voltage drop (950 mV vs. 900 mV) and reverse recovery time (35 ns vs. 25 ns) must be evaluated for specific circuit requirements. The higher voltage rating provides design margin but does not reduce forward voltage drop or switching speed. Verify circuit performance under actual operating conditions.
