Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical parameter alignment with the main part SSA23LHE3_A/I:

Parametric Equivalents (Full Electrical Match): Parts that match all critical electrical parameters—30 V reverse voltage, 2 A average rectified current, 450 mV forward voltage at 2 A, and fast recovery speed characteristics—are classified as parametric equivalents. These parts differ only in packaging format (Tape & Reel versus Cut Tape) and inventory availability. Parametric equivalents include SSA23L-E3/5AT and SSA23L-E3/61T, both from Vishay General Semiconductor - Diodes Division.

Manufacturer Recommended Substitutes (Electrical Variations): Parts that maintain the 30 V reverse voltage and 2 A current rating but exhibit variations in forward voltage, reverse leakage current, or other secondary parameters are classified as manufacturer recommended substitutes. These include B230A-13-F (Diodes Incorporated), STPS2L30A (STMicroelectronics), and lower-current alternatives STPS130A and STPS1L30A (STMicroelectronics). Selection among these substitutes depends on application tolerance for forward voltage drop, reverse leakage characteristics, and thermal performance requirements.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): 30 V (mandatory match)
Current - Average Rectified (Io): 2 A (for full equivalents) or 1 A (for reduced-current alternatives)
Technology: Schottky (mandatory match)
Package / Case: DO-214AC, SMA (mandatory match)
Mounting Type: Surface Mount (mandatory match)

Engineering Selection Recommendations

Full Parametric Equivalents (SSA23L-E3/5AT, SSA23L-E3/61T): These Vishay parts are direct electrical equivalents to SSA23LHE3_A/I with identical voltage, current, and forward voltage specifications. Selection between these two depends on packaging format requirements: SSA23L-E3/5AT is supplied in Tape & Reel format with 18,360 pieces in stock, while SSA23L-E3/61T is supplied in Cut Tape format with 32,600 pieces in stock. Both maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. These parts are suitable for direct replacement in applications where the original part is unavailable.

Manufacturer Recommended Substitute (B230A-13-F): The Diodes Incorporated B230A-13-F maintains 30 V reverse voltage and 2 A current rating with a forward voltage specification of 500 mV at 2 A, representing a 50 mV increase over the main part. This part is suitable for applications where the additional forward voltage drop is acceptable within circuit design margins. B230A-13-F is available in Cut Tape & Digi-Reel format with 64,245 pieces in stock and meets ROHS3 compliance and MSL 1 requirements.

Manufacturer Recommended Substitute (STPS2L30A): The STMicroelectronics STPS2L30A matches the 30 V reverse voltage and 2 A current rating with identical 450 mV forward voltage at 2 A. This part exhibits reduced reverse leakage current (200 µA versus 500 µA), which may provide improved performance in low-leakage applications. STPS2L30A is available in Cut Tape & Digi-Reel format with 18,661 pieces in stock and meets ROHS3 compliance and MSL 1 requirements.

Lower-Current Alternatives (STPS1L30A, STPS130A): These STMicroelectronics parts are rated for 1 A average rectified current and are suitable only for applications where the circuit current requirement does not exceed 1 A. STPS1L30A offers 395 mV forward voltage at 1 A with 200 µA reverse leakage, while STPS130A offers 550 mV forward voltage at 1 A with significantly reduced 10 µA reverse leakage. Both parts maintain 30 V reverse voltage rating and fast recovery speed characteristics. These alternatives are not suitable for direct replacement in 2 A applications.

All substitute parts maintain Active product status, ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with automotive and industrial qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can SSA23L-E3/5AT and SSA23L-E3/61T be used interchangeably with SSA23LHE3_A/I?

A: Yes. Both parts are parametric equivalents with identical electrical specifications: 30 V reverse voltage, 2 A average rectified current, 450 mV forward voltage at 2 A, and fast recovery speed. The only difference is packaging format: SSA23L-E3/5AT is supplied in Tape & Reel, while SSA23L-E3/61T is supplied in Cut Tape. Selection depends on assembly process requirements and inventory availability.

Q: What is the difference between B230A-13-F and SSA23LHE3_A/I?

A: B230A-13-F is manufactured by Diodes Incorporated and differs in forward voltage specification: 500 mV at 2 A compared to 450 mV at 2 A for the main part. All other electrical parameters—30 V reverse voltage, 2 A current rating, fast recovery speed, and 500 µA reverse leakage—are identical. The 50 mV forward voltage increase must be evaluated against circuit design margins.

Q: Can STPS1L30A or STPS130A replace SSA23LHE3_A/I in a 2 A application?

A: No. STPS1L30A and STPS130A are rated for maximum 1 A average rectified current and are not suitable for applications requiring 2 A. Using a 1 A rated diode in a 2 A circuit will result in device failure. These parts are suitable only for applications where circuit current does not exceed 1 A.

Q: What is the advantage of STPS2L30A over SSA23LHE3_A/I?

A: STPS2L30A maintains identical voltage and current ratings with matching 450 mV forward voltage at 2 A. The primary advantage is reduced reverse leakage current: 200 µA at 30 V compared to 500 µA for the main part. This characteristic is beneficial in low-leakage or precision rectification applications. All other parameters remain equivalent.

Q: Are all substitute parts automotive qualified?

A: SSA23LHE3_A/I carries AEC-Q101 automotive qualification. The parametric equivalents SSA23L-E3/5AT and SSA23L-E3/61T are from the same manufacturer and series. The manufacturer recommended substitutes (B230A-13-F, STPS2L30A, STPS1L30A, STPS130A) are not explicitly listed with AEC-Q101 qualification in the provided specifications. Verification of automotive qualification status is required for applications with automotive qualification requirements.

Q: What is the difference in packaging between Tape & Reel and Cut Tape formats?

A: Tape & Reel format (SSA23L-E3/5AT) supplies components on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape format (SSA23L-E3/61T, B230A-13-F, STPS2L30A, STPS1L30A, STPS130A) supplies components on tape segments, suitable for lower-volume or mixed-component assembly. Both formats use identical DO-214AC (SMA) package geometry and are mechanically compatible with standard surface mount assembly equipment.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: Yes. All listed substitute parts—SSA23L-E3/5AT, SSA23L-E3/61T, B230A-13-F, STPS2L30A, STPS1L30A, and STPS130A—are ROHS3 compliant and REACH Unaffected. All parts maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the operating temperature range for these diodes?

A: SSA23LHE3_A/I operates from -65°C to 150°C junction temperature. All substitute parts maintain the same maximum junction temperature of 150°C. The minimum operating temperature for STMicroelectronics parts (STPS2L30A, STPS1L30A, STPS130A) is not specified in the provided data; verification is required for applications requiring operation below -65°C.
