Engineering Selection Recommendations

B360A-E3/61T (Vishay General Semiconductor - Diodes Division)

This part is a direct electrical equivalent with 60V reverse voltage rating and 3A current capacity. Forward voltage is 720 mV at 3A, representing a 20 mV increase over the ACDBA360-HF. Reverse leakage current is 200 µA at 60V, lower than the main part. Operating temperature range extends to 150°C, providing enhanced thermal margin. ROHS3 compliance and MSL 1 rating match the original specification. Packaging is Cut Tape (CT), differing from the main part's Tape & Reel format.

SK36A (Good-Ark Semiconductor)

This part meets all primary electrical specifications with 60V reverse voltage and 3A current rating. Forward voltage matches at 700 mV at 3A. Reverse leakage current is 150 µA at 60V, the lowest among substitutes. Operating temperature range extends to 150°C. AEC-Q101 automotive qualification is present. Capacitance is 250 pF at 4V, 1MHz, higher than the main part. ROHS3 compliance and MSL 1 rating are confirmed. Packaging is available in Tape & Reel (TR) format, matching the main part's packaging type.

VSSA36S-M3/61T (Vishay General Semiconductor - Diodes Division, TMBS® Series)

This part has a reduced current rating of 2.4A, below the 3A specification of the main part. Reverse voltage rating is 60V, matching the primary requirement. Forward voltage is 630 mV at 3A, the lowest among all options. Reverse leakage current is 900 µA at 60V, the highest among substitutes. Operating temperature range extends to 150°C. ROHS3 compliance and MSL 1 rating are confirmed. Packaging is Tape & Reel (TR) format. The reduced current capacity limits this part to applications where 2.4A maximum current is acceptable.

Frequently Asked Questions (FAQ)

Q1: Can B360A-E3/61T replace ACDBA360-HF in all applications?

B360A-E3/61T meets the core electrical specifications: 60V reverse voltage, 3A current capacity, and DO-214AC package compatibility. Forward voltage is 20 mV higher (720 mV vs. 700 mV at 3A). The primary difference is packaging format: B360A-E3/61T is supplied in Cut Tape (CT) while ACDBA360-HF is Tape & Reel (TR). Verify your assembly equipment compatibility with the packaging format before selection.

Q2: What is the significance of the current rating difference with VSSA36S-M3/61T?

VSSA36S-M3/61T is rated for 2.4A average rectified current, compared to 3A for the main part. This part is suitable only for applications where the maximum required current does not exceed 2.4A. For circuits requiring the full 3A capacity, this substitute is not appropriate.

Q3: How do reverse leakage current differences affect circuit performance?

Reverse leakage current values range from 150 µA (SK36A) to 900 µA (VSSA36S-M3/61T) at 60V. The main part specifies 500 µA. Lower leakage current reduces power dissipation in reverse bias conditions. Higher leakage current increases standby power consumption. Select based on your circuit's reverse bias operating conditions and power budget requirements.

Q4: Are all substitute parts automotive qualified?

SK36A carries AEC-Q101 automotive qualification, matching the main part. B360A-E3/61T and VSSA36S-M3/61T do not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring AEC-Q101 certification, SK36A is the appropriate substitute.

Q5: What is the impact of operating temperature range differences?

ACDBA360-HF operates from -55°C to 125°C. All three substitutes extend the upper limit to 150°C. This provides additional thermal margin in high-temperature environments. If your application operates within the -55°C to 125°C range, all parts are compatible. For applications exceeding 125°C, the substitutes offer extended thermal capability.

Q6: How do capacitance values affect high-frequency performance?

Capacitance at 4V, 1MHz is 150 pF for the main part, 145 pF for B360A-E3/61T, and 245-250 pF for SK36A and VSSA36S-M3/61T. Higher capacitance increases junction capacitance effects at high switching frequencies. For applications with stringent high-frequency requirements, B360A-E3/61T offers the lowest capacitance value.

Q7: Are all parts ROHS3 compliant?

All four parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, confirming compatibility with standard PCB assembly and storage procedures.
