Substitute Part Grouping Explanation

Substitution of the SR806H is determined by strict equivalence in the following parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V
Technology: Schottky
Package / Case: DO-201AD, Axial
Mounting Type: Through Hole
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Secondary Compatibility Criteria:

Current - Average Rectified (Io): Equal or greater than 8 A
Voltage - Forward (Vf) (Max) @ If: Within acceptable operating range
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: Within acceptable operating range
Operating Temperature - Junction: Minimum -55°C, maximum 150°C

Substitute parts are grouped into two categories:

Category 1 - Parametric Equivalent (Identical Electrical Specifications): SR806 (Taiwan Semiconductor Corporation, Cut Tape packaging) maintains identical electrical ratings and temperature range.

Category 2 - Similar Parts (Reduced Current Rating): SB360-E3/54, SB360-E3/73, and SR306-TP are rated for 3 A average rectified current, which is lower than the SR806H 8 A specification. These parts maintain 60 V reverse voltage rating and DO-201AD package compatibility but are suitable only for applications requiring ≤ 3 A current.

Category 3 - Similar Parts (Intermediate Current Rating): SB560-E3/54, SB560-E3/73, SB560-T, and STPS5L60 are rated for 5 A average rectified current, which is lower than the SR806H 8 A specification. These parts maintain 60 V reverse voltage rating and DO-201AD package compatibility but are suitable only for applications requiring ≤ 5 A current.

Engineering Selection Recommendations

Full Parametric Equivalent: SR806 (Taiwan Semiconductor Corporation) is the direct parametric equivalent to SR806H, differing only in packaging configuration (Cut Tape versus Tape & Reel). Both parts maintain identical electrical specifications, temperature range, and regulatory compliance. Selection between SR806H and SR806 depends on packaging and supply chain requirements.

Current-Reduced Alternatives: Parts rated for 3 A or 5 A average rectified current (SB360-E3/54, SB360-E3/73, SB560-E3/54, SB560-E3/73, SB560-T, SR306-TP, STPS5L60) are suitable only for applications where the circuit design permits operation at reduced current levels. These parts maintain the 60 V reverse voltage rating and DO-201AD package compatibility required for mechanical and thermal fit. Selection of current-reduced alternatives requires circuit-level analysis to confirm that maximum current demand does not exceed the substitute part rating.

All listed substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory compatibility with the original SR806H specification.

Frequently Asked Questions (FAQ)

Q: Can SR806 replace SR806H in all applications? A: Yes. SR806 is a parametric equivalent with identical electrical specifications (60 V, 8 A, 700 mV forward voltage at 8 A, -55°C to 150°C operating range). The only difference is packaging format (Cut Tape versus Tape & Reel). Both parts are ROHS3 compliant and MSL Level 1.

Q: Can SB560-E3/54 or SB560-E3/73 replace SR806H? A: SB560-E3/54 and SB560-E3/73 are suitable only if the application circuit is designed for maximum 5 A average rectified current. Both parts maintain 60 V reverse voltage rating and DO-201AD package compatibility. Forward voltage is 650 mV at 5 A, compared to 700 mV at 8 A for SR806H. These parts are not direct replacements for 8 A applications.

Q: Can SB360-E3/54 or SB360-E3/73 replace SR806H? A: SB360-E3/54 and SB360-E3/73 are suitable only if the application circuit is designed for maximum 3 A average rectified current. Both parts maintain 60 V reverse voltage rating and DO-201AD package compatibility. These parts are not direct replacements for 8 A applications.

Q: What is the difference between SR806H and SR806? A: SR806H is supplied in Tape & Reel (TR) packaging, while SR806 is supplied in Cut Tape (CT) packaging. Electrical specifications, temperature range, and regulatory compliance are identical. Selection depends on assembly equipment compatibility and supply chain logistics.

Q: Are all substitute parts automotive-qualified? A: SR806H carries AEC-Q101 automotive qualification. Substitute parts listed do not explicitly state AEC-Q101 qualification in the provided specifications. Applications requiring automotive qualification should confirm qualification status with the manufacturer before selection.

Q: Can STPS5L60 replace SR806H? A: STPS5L60 is suitable only if the application circuit is designed for maximum 5 A average rectified current. STPS5L60 offers superior forward voltage performance (520 mV at 5 A versus 700 mV at 8 A for SR806H) and lower reverse leakage (220 µA versus 500 µA). However, it is not a direct replacement for 8 A applications. Operating temperature range is -55°C to 150°C, matching SR806H.

Q: Can SR306-TP replace SR806H? A: SR306-TP is suitable only if the application circuit is designed for maximum 3 A average rectified current. SR306-TP maintains 60 V reverse voltage rating and DO-201AD package compatibility. Operating temperature range is -55°C to 125°C, which is narrower than SR806H (-55°C to 150°C). Reverse leakage is 1 mA at 60 V, higher than SR806H (500 µA). This part is not a direct replacement for 8 A applications.

Q: Do all substitute parts use the same DO-201AD package? A: Yes. All listed substitute parts use DO-201AD axial through-hole package, ensuring mechanical and thermal compatibility with SR806H in PCB designs and assembly processes.

Q: What is the difference between SB560-E3/54 and SB560-E3/73? A: Both parts are manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical specifications (60 V, 5 A, 650 mV forward voltage at 5 A, -65°C to 150°C). The difference is in packaging tape configuration (54 and 73 designate different tape specifications). Electrical performance is equivalent.
