ES1C-13 Equivalent & Substitute Parts

Part Overview

The ES1C-13 is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 150 V DC reverse voltage and 1 A average rectified current in a surface mount SMA package. This part is classified as discontinued at DiGi Electronics, creating a requirement to identify equivalent and substitute components for ongoing design support and procurement.

The ES1C-13 operates as a fast recovery diode with a reverse recovery time of 25 nanoseconds, suitable for standard rectification applications requiring moderate voltage and current ratings. Equivalent and substitute parts are identified based on matching electrical performance parameters and mechanical compatibility within the DO-214AC (SMA) package family.

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 1 A
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Parameters:

Voltage - Forward (Vf) (Max) @ If: 920 mV @ 1 A (tolerance range acceptable)
Reverse Recovery Time (trr): 25 ns (nominal reference)
Current - Reverse Leakage @ Vr: 5 µA @ 150 V (nominal reference)

Engineering Selection Recommendations

Primary Recommendation: ES1C-13-F

The ES1C-13-F is the direct manufacturer equivalent from Diodes Incorporated. This part maintains identical electrical specifications to the ES1C-13 while offering active product status and RoHS3 compliance. The ES1C-13-F differs only in packaging format (Tape & Reel), making it the optimal choice for direct replacement in production environments. Inventory availability is substantial at 10,300 pieces.

Secondary Recommendations: Vishay Parts (ES1C-E3/61T, ES1C-E3/5AT, ES1CHE3_A/H)

The Vishay General Semiconductor - Diodes Division parts ES1C-E3/61T, ES1C-E3/5AT, and ES1CHE3_A/H provide parametric equivalence with identical electrical performance to the ES1C-13. All three parts are active, RoHS3 compliant, and available in high quantities. The ES1C-E3/61T offers the highest inventory level at 48,300 pieces. The ES1CHE3_A/H variant includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can ES1C-13-F be used as a direct replacement for ES1C-13?

A: Yes. The ES1C-13-F is electrically and mechanically identical to the ES1C-13. The only difference is packaging format (Tape & Reel vs. bulk). Both parts are rated for 150 V, 1 A, and use the DO-214AC (SMA) package. The ES1C-13-F is active and RoHS3 compliant.

Q: What is the difference between the Vishay parts (ES1C-E3/61T, ES1C-E3/5AT, ES1CHE3_A/H)?

A: All three Vishay parts share identical electrical specifications matching the ES1C-13. The primary differences are packaging format and qualification level. ES1C-E3/61T and ES1CHE3_A/H are supplied in Tape & Reel format. ES1C-E3/5AT is supplied in Cut Tape & Digi-Reel format. ES1CHE3_A/H includes AEC-Q101 automotive qualification for applications requiring automotive-grade components.

Q: Is the EGF1C from Fairchild Semiconductor a suitable substitute?

A: The EGF1C meets the primary voltage (150 V) and current (1 A) specifications and uses the same DO-214AC (SMA) package. However, it exhibits higher reverse recovery time (50 ns vs. 25 ns), higher reverse leakage current (10 µA vs. 5 µA), and higher junction capacitance (15 pF vs. 10 pF). The EGF1C is suitable for applications where these parameter variations are acceptable and extended operating temperature range (-65°C to 175°C) is beneficial.

Q: What does RoHS3 compliance mean for the substitute parts?

A: RoHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3, restricting the use of specific hazardous materials in electrical and electronic equipment. The ES1C-13 is RoHS non-compliant, while ES1C-13-F, ES1C, and all Vishay parts are RoHS3 compliant. RoHS3 compliance is required for many applications, particularly in consumer electronics and regulated industries.

Q: Can I use the Taiwan Semiconductor Corporation ES1C part?

A: Yes. The ES1C meets primary substitution criteria with 150 V reverse voltage and 1 A current rating in the DO-214AC (SMA) package. The part is active and RoHS3 compliant. Forward voltage is slightly higher (950 mV vs. 920 mV) and reverse recovery time is slightly higher (35 ns vs. 25 ns), but both remain within acceptable ranges for general-purpose rectification applications.

Q: What is the significance of AEC-Q101 qualification on the ES1CHE3_A/H?

A: AEC-Q101 is an automotive electronics qualification standard. The ES1CHE3_A/H variant meets this qualification, making it suitable for automotive applications requiring qualified components. If your application does not require automotive qualification, other Vishay parts (ES1C-E3/61T, ES1C-E3/5AT) provide identical electrical performance without the automotive qualification overhead.

Q: Are all substitute parts available in the same package?

A: Yes. All substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical compatibility with the ES1C-13. Packaging formats differ (Tape & Reel, Cut Tape, Bulk), but the physical component package remains identical, allowing direct PCB placement without modification.

Q: Which substitute part has the best inventory availability?

A: The ES1C-E3/61T from Vishay General Semiconductor - Diodes Division has the highest inventory availability at 48,300 pieces. The ES1CHE3_A/H is also well-stocked at 47,474 pieces. Both parts offer identical electrical specifications to the ES1C-13 with active product status and RoHS3 compliance.
