Engineering Selection Recommendations

All three parts—1PS76SB21F, 1PS76SB21,115, and 1PS76SB21Z—are active products manufactured by Nexperia USA Inc. and carry identical electrical specifications and mechanical compatibility. Selection between these parts is based on availability and packaging designation:

1PS76SB21F: Primary part number with 10,907 units in stock. ROHS3 compliant, MSL 1 (Unlimited), suitable for standard procurement.

1PS76SB21,115: Parametric equivalent with 12,300 units in stock. ROHS3 compliant, MSL 1 (Unlimited). Capacitance specification is 50 pF @ 0V, 1MHz, compared to 40 pF for the primary part. This variation does not affect substitution eligibility within the defined electrical parameter set.

1PS76SB21Z: Parametric equivalent with 30,702 units in stock. ROHS3 compliant, MSL 1 (Unlimited). Capacitance specification matches the primary part at 40 pF @ 0V, 1MHz. Highest inventory availability.

All parts meet REACH unaffected status and EAR99 export classification. Direct substitution is supported across all three part numbers for applications requiring 40 V, 200 mA Schottky rectifier diodes in SOD-323 surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can 1PS76SB21,115 be used as a direct replacement for 1PS76SB21F?

A: Yes. Both parts share identical voltage ratings (40 V), current ratings (200 mA), forward voltage characteristics (550 mV @ 200 mA), reverse leakage (15 µA @ 30 V), package type (SOD-323), and compliance certifications (ROHS3, MSL 1). The capacitance difference (50 pF versus 40 pF) does not affect substitution eligibility based on the defined electrical parameter set.

Q: Can 1PS76SB21Z be used as a direct replacement for 1PS76SB21F?

A: Yes. Both parts are identical across all critical electrical parameters, package specifications, and compliance certifications. Capacitance values match at 40 pF @ 0V, 1MHz.

Q: Are there any package or mounting differences between these parts?

A: No. All three parts use the SC-76, SOD-323 surface mount package and are compatible with identical PCB layouts and reflow soldering processes.

Q: What is the significance of the capacitance variation in 1PS76SB21,115?

A: The capacitance specification of 50 pF @ 0V, 1MHz for 1PS76SB21,115 compared to 40 pF for 1PS76SB21F and 1PS76SB21Z represents a manufacturing tolerance variation within the same product family. This parameter does not affect the core rectification function or substitution compatibility for applications within the specified electrical operating range.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage conditions.

Q: Which part should be selected based on availability?

A: Selection should be based on procurement requirements and supply chain considerations. 1PS76SB21Z has the highest inventory (30,702 units), followed by 1PS76SB21,115 (12,300 units) and 1PS76SB21F (10,907 units). All three are active products with equivalent electrical and mechanical specifications.
