ES1C Equivalent & Substitute Parts
Part Overview
The ES1C is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 150 V DC reverse voltage and 1 A average rectified current. The device is packaged in DO-214AC (SMA) surface mount configuration and is classified as a fast recovery diode with a reverse recovery time of 35 nanoseconds. This component is suitable for applications requiring efficient rectification in low-to-medium power circuits with moderate voltage requirements.
The ES1C maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1). Identifying equivalent substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate alternative sourcing options while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation
Substitute parts for the ES1C are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:
Mandatory Matching Parameters:
- Voltage - DC Reverse (Vr) (Max): 150 V
- Current - Average Rectified (Io): 1 A
- Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
- Reverse Recovery Time (trr): 35 ns
- Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
- Package / Case: DO-214AC, SMA
- Mounting Type: Surface Mount
- Operating Temperature - Junction: -55°C to 150°C
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level (MSL): 1 (Unlimited)
Allowable Parameter Variations:
- Current - Reverse Leakage @ Vr: May vary within acceptable limits
- Capacitance @ Vr, F: May vary within acceptable limits
- Manufacturer: Different manufacturers permitted
- Packaging Format: Tape & Reel (TR) or equivalent acceptable
The substitute part ES1C_R1_00001 from Panjit International Inc. meets all mandatory matching criteria and is therefore classified as a parametric equivalent.

Engineering Selection Recommendations
The ES1C_R1_00001 from Panjit International Inc. is a direct parametric equivalent to the ES1C from Taiwan Semiconductor Corporation. Both devices share identical electrical ratings for voltage, current, forward voltage drop, and reverse recovery time. Both maintain Active product status and are fully RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification.
The ES1C_R1_00001 exhibits lower reverse leakage current (1 µA versus 5 µA at 150 V) and lower junction capacitance (7 pF versus 16 pF at 4V, 1MHz), which represent performance improvements over the primary part. These variations are within acceptable tolerances for general-purpose rectifier applications and do not compromise functional compatibility.
Both parts are supplied in DO-214AC (SMA) surface mount packaging and operate across the identical temperature range of -55°C to 150°C. The substitute part is available in Tape & Reel (TR) packaging format, which is standard for high-volume surface mount assembly operations.
Selection between these parts is determined by availability, supply chain requirements, and packaging format preferences. No functional limitations exist for direct substitution in circuit designs specified for the ES1C.
