Engineering Selection Recommendations

SS22HE3_A/I and SK22_R1_00001 are active and ROHS3 compliant, with REACH unaffected status and identical packaging and parametric values. SS22T3G is listed as Last Time Buy; in applications where active status and long-term availability are required, SK22_R1_00001 and SS22HE3_A/I are preferable. Only listed compliance and product statuses are considered.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for substituting the SS22HE3_A/I diode?
A: Substitution is determined by matching technology (Schottky), DC reverse voltage, average rectified current, forward voltage at load, recovery speed, surface mount package (DO-214AA, SMB), and compliance statuses.

Q: Is package compatibility ensured among listed substitutes?
A: All substitute parts use the same enclosure: DO-214AA, SMB, suitable for direct surface mount replacement.

Q: Are reverse leakage characteristics identical among substitutes?
A: Current - reverse leakage values differ: SS22HE3_A/I and SS22T3G have 400 µA (at 20 V for SS22HE3_A/I, at 40 V for SS22T3G), SK22_R1_00001 is 90 µA at 20 V. Only specified values are presented.

Q: What should be considered regarding product status?
A: Product status affects supply longevity. SS22HE3_A/I and SK22_R1_00001 are active; SS22T3G is Last Time Buy.

Q: Are qualification and grade parameters matched among substitutes?
A: Only SS22HE3_A/I explicitly lists Grade: Automotive and Qualification: AEC-Q101 in the provided data. Other substitutes do not specify these fields in the input.

Q: What compliance and regulatory statuses are relevant for selection?
A: All parts listed are ROHS3 compliant and REACH unaffected, with MSL 1 (Unlimited), meeting standard regulatory and handling requirements as per provided data.
