Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GS2A-LTP are identified based on the following criteria:

Parametric Equivalent Classification: Parts that match all critical electrical parameters including voltage rating (50V), current rating (2A), forward voltage drop (1.1V @ 2A), reverse leakage current (5µA @ 50V), and package form factor (DO-214AC/SMA).

Similar Substitute Classification: Parts that share the same package and voltage rating but differ in current capacity or recovery characteristics. These substitutes are suitable when circuit design permits operation at reduced current ratings or when recovery speed differences are acceptable.

Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 50V minimum
• Package / Case: DO-214AC (SMA) surface mount
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent: S2A-HF (Comchip Technology)

The S2A-HF is a parametric equivalent to the GS2A-LTP. Both components share identical voltage ratings (50V), current ratings (2A), forward voltage characteristics (1.1V @ 2A), reverse leakage current (5µA @ 50V), and recovery speed classification (Standard Recovery >500ns). Both are housed in DO-214AC (SMA) surface mount packages with identical operating temperature ranges (-55°C to 150°C). Both components are RoHS3 compliant with MSL 1 rating. Direct substitution is supported without circuit modification.

Similar Substitute: US1A-E3/5AT (Vishay General Semiconductor)

The US1A-E3/5AT is classified as a similar substitute due to reduced current rating (1A versus 2A). This component shares the same 50V voltage rating, DO-214AC (SMA) package, and operating temperature range. The US1A-E3/5AT features fast recovery characteristics (≤500ns with 50ns trr) compared to the standard recovery of the GS2A-LTP. This substitute is suitable for applications where circuit current requirements do not exceed 1A and where faster recovery characteristics provide circuit benefit. RoHS3 compliance and MSL 1 rating are maintained.

Product Status and Compliance: All identified substitutes maintain Active product status and full RoHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the S2A-HF directly replace the GS2A-LTP without circuit modification?

A: Yes. The S2A-HF is a parametric equivalent with matching voltage (50V), current (2A), forward voltage (1.1V @ 2A), reverse leakage (5µA @ 50V), and package specifications (DO-214AC/SMA). No circuit modification is required.

Q: Under what conditions can the US1A-E3/5AT substitute for the GS2A-LTP?

A: The US1A-E3/5AT can substitute when circuit design permits operation at 1A maximum current instead of 2A. The 50V voltage rating, DO-214AC package, and operating temperature range remain compatible. The faster recovery speed (≤500ns versus >500ns) is an additional characteristic that may benefit certain circuit topologies.

Q: What is the significance of the DO-214AC (SMA) package specification?

A: The DO-214AC (SMA) package is a surface mount form factor with standardized dimensions and pin configuration. All listed substitutes use this identical package, ensuring mechanical and electrical compatibility on printed circuit boards without layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The GS2A-LTP, S2A-HF, and US1A-E3/5AT are all RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting regulatory requirements for environmental and hazardous substance restrictions.

Q: How does reverse recovery time affect substitution suitability?

A: Reverse recovery time (trr) is specified only for the US1A-E3/5AT (50ns). The GS2A-LTP and S2A-HF are classified as standard recovery devices without specific trr values. In applications sensitive to switching transients or high-frequency operation, the US1A-E3/5AT's faster recovery may provide performance advantages, though current rating limitations must be observed.

Q: What is the difference between standard recovery and fast recovery diodes?

A: Standard recovery diodes (GS2A-LTP, S2A-HF) have recovery times exceeding 500ns, suitable for general-purpose rectification. Fast recovery diodes (US1A-E3/5AT) have recovery times of 500ns or less, beneficial in switching power supplies and high-frequency applications where reduced switching losses are required.

Q: Can the GS2A-LTP be used in applications requiring the US1A-E3/5AT specifications?

A: No. The GS2A-LTP has standard recovery characteristics (>500ns) versus the US1A-E3/5AT's fast recovery (≤500ns). Additionally, the GS2A-LTP is rated for 2A while the US1A-E3/5AT is rated for 1A. Substitution in the reverse direction is not supported.
