Current - Average Rectified (Io): 1 A minimum
Package / Case: DO-214AC, SMA (surface mount)
Mounting Type: Surface Mount
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

Engineering Selection Recommendations

Full Electrical and Mechanical Equivalents (150 V / 1 A / Fast Recovery):

The following parts meet all primary substitution criteria and are suitable for direct replacement in applications requiring 150 V reverse voltage, 1 A average rectified current, and fast recovery characteristics:

ES1C-13-F (Diodes Incorporated): Identical reverse recovery time (25 ns), forward voltage within 20 mV of main part, RoHS3 compliant, MSL 1, operating temperature -55 to 150°C
ESH2CA (Taiwan Semiconductor Corporation): Parametric equivalent with identical forward voltage (900 mV) and reverse recovery time (25 ns), RoHS3 compliant, MSL 1, extended temperature range to 175°C

Enhanced Performance Alternatives (150 V / 1 A):

STPS1150A (STMicroelectronics): Schottky technology with lower forward voltage (820 mV), 150 V rating, 1 A current, RoHS3 compliant, suitable for applications prioritizing reduced forward voltage drop
SBR1U150SA-13 (Diodes Incorporated): Super Barrier technology with lowest forward voltage (700 mV), 150 V rating, 1 A current, AEC-Q101 automotive qualification, RoHS3 compliant, MSL 1, suitable for automotive and high-efficiency applications

Reduced Voltage Alternatives (100 V / 1 A):

The following parts are suitable only for applications where 100 V reverse voltage rating is sufficient:

ES1C-13-F (Diodes Incorporated): 100 V rating, 1 A current, fast recovery, RoHS3 compliant
US1B-13-F (Diodes Incorporated): 100 V rating, 1 A current, fast recovery, RoHS3 compliant, extended temperature range to -65°C
S1B-13-F (Diodes Incorporated): 100 V rating, 1 A current, standard recovery, RoHS3 compliant

Selection Basis:

All recommended substitutes maintain Active product status and RoHS3 compliance. Parts with MSL 1 (Unlimited) are preferred for handling and storage consistency. Operating temperature ranges should be verified against application requirements. Technology selection (Standard, Schottky, Super Barrier) depends on forward voltage drop and efficiency priorities.

Frequently Asked Questions (FAQ)

Q: Can STPS1150A replace ESH1C-E3/5AT directly?

A: STPS1150A is electrically compatible with identical 150 V reverse voltage and 1 A current ratings in the same DO-214AC (SMA) package. The Schottky technology provides lower forward voltage (820 mV vs. 900 mV), which reduces power dissipation. Substitution is valid for applications where Schottky diode characteristics are acceptable.

Q: What is the difference between ES1C-13-F and ESH1C-E3/5AT?

A: Both parts are 150 V / 1 A general-purpose rectifiers in DO-214AC (SMA) packages with identical reverse recovery time (25 ns). ES1C-13-F has slightly higher forward voltage (920 mV vs. 900 mV) and lower reverse leakage current (5 µA vs. 1 µA). Operating temperature range differs: ES1C-13-F is -55 to 150°C versus -55 to 175°C for ESH1C-E3/5AT. Both are RoHS3 compliant with MSL 1.

Q: Can I use S1B-13-F or US1B-13-F as substitutes?

A: S1B-13-F and US1B-13-F are rated for 100 V reverse voltage, which is lower than the ESH1C-E3/5AT 150 V rating. These parts are suitable only for applications where the circuit operates at 100 V or below. They are not suitable for circuits designed for 150 V operation.

Q: What is the advantage of SBR1U150SA-13?

A: SBR1U150SA-13 uses Super Barrier technology and provides the lowest forward voltage (700 mV) among 150 V / 1 A alternatives, resulting in reduced power dissipation and heat generation. It includes AEC-Q101 automotive qualification and is suitable for automotive and efficiency-critical applications. Reverse leakage current is higher (100 µA vs. 1 µA), which may be a consideration in high-impedance circuits.

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

A: All listed substitute parts use the DO-214AC (SMA) surface mount package, ensuring mechanical compatibility. Packaging format (Tape & Reel, Cut Tape, Bulk) may differ between manufacturers and suppliers but does not affect electrical or mechanical fit.

Q: What does RoHS3 compliance mean for substitution?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements and is suitable for use in regulated markets. All recommended substitutes are RoHS3 compliant, ensuring regulatory alignment with the original ESH1C-E3/5AT.

Q: Can I use US1J-13-F in place of ESH1C-E3/5AT?

A: US1J-13-F is rated for 600 V reverse voltage and 1 A current in the same DO-214AC (SMA) package. While electrically compatible from a current perspective, the higher voltage rating results in higher forward voltage (1700 mV vs. 900 mV) and longer reverse recovery time (75 ns vs. 25 ns). Substitution is valid only if the application can tolerate increased forward voltage drop and slower switching characteristics.

Q: What is the difference between ESH2CA and ESH1C-E3/5AT?

A: ESH2CA is a parametric equivalent with identical 150 V / 1 A ratings, forward voltage (900 mV), and reverse recovery time (25 ns). The primary difference is the reverse leakage current specification: ESH2CA is specified at 200 V (1 µA) versus 150 V (1 µA) for ESH1C-E3/5AT. ESH2CA offers extended temperature range to 175°C. Both are RoHS3 compliant with MSL 1.

Q: How do I determine which substitute is best for my application?

A: Verify the following application requirements: (1) Required reverse voltage rating—select parts rated at or above your circuit voltage; (2) Forward voltage drop tolerance—lower values reduce power dissipation; (3) Switching speed requirements—fast recovery (≤ 500ns) for high-frequency applications; (4) Operating temperature range—confirm part rating covers your thermal environment; (5) Regulatory requirements—all listed parts are RoHS3 compliant. Cross-reference these requirements against the Parameter Comparison table to identify suitable alternatives.
