Each category below includes representative part numbers and an explanation of their typical use cases, helping readers understand why these models appear so frequently in global sourcing activities.
Small-Signal & Schottky Diodes
Small-signal and Schottky diodes represent one of Nexperia’s strongest product lines. These devices are widely used for signal switching, voltage clamping, reverse polarity protection, and power rectification in low- to medium-power circuits.
Switching and Signal Diodes
Models such as BAV99, BAV70, BAV74, and BAV199 are among the most frequently searched Nexperia part numbers. The BAV99 dual switching diode, in particular, is extremely popular due to its compact package, fast switching speed, and suitability for signal routing, logic level shifting, and protection circuits.
Closely related BAS-series diodes, including BAS16, BAS21, BAS28, BAS316, and BAS321, are commonly used where low leakage current and fast recovery time are required. Variants such as BAS16J, BAS16L, and QX or automotive-specified versions are often selected in designs requiring enhanced reliability or specific packaging.
These diodes frequently appear in:
- Signal conditioning circuits
- Digital input protection
- Communication interfaces
- Low-voltage switching applications
Schottky Diodes for Power and Signal Applications
Schottky diodes such as BAT54S, BAT54C, BAT54SW, BAT74, and BAT46WJ are widely used due to their low forward voltage and fast response. BAT54 variants are especially common in battery-powered devices, voltage clamping, and OR-ing circuits.
For higher current and power applications, Nexperia’s PMEG series—including PMEG4010EH, PMEG6010CEJ, PMEG6020ER, PMEG10010ELR, and PMEG4020EPK—is heavily adopted in DC-DC converters, power adapters, and industrial power supplies. These devices balance efficiency, thermal performance, and compact packaging, making them attractive for both engineers and buyers.
Bipolar Transistors (NPN / PNP)
Despite the widespread use of MOSFETs, bipolar transistors remain essential in many analog and low-power switching designs. Nexperia’s BC and PBSS transistor families continue to see strong demand.
General-Purpose Transistors
Models such as BC817-40, BC846B, BC847B, BC856B, and BC857B are classic general-purpose BJTs used in amplification, switching, and signal control. Among them, BC817-40 is one of the most searched NPN transistors due to its versatility and suitability for mass production.
PNP counterparts such as BC856B and BC857C are often paired with NPN devices to form complementary circuits. Automotive-qualified or QR variants are frequently selected in designs requiring higher reliability standards.
Medium-Power and Specialty BJTs
Transistors like BC807-40, BCX52-16, BCX56-16, and BCP56-16 support higher current handling while maintaining compact footprints. These are commonly used in power switching, relay driving, and industrial control circuits.
The PBSS series (e.g., PBSS4041, PBSS4330, PBSS5360) integrates high-gain characteristics and improved thermal behavior, making them suitable for modern compact designs.
MOSFETs
MOSFETs represent another core area of Nexperia’s product portfolio, ranging from small-signal devices to robust power MOSFETs.
Small-Signal MOSFETs
Few MOSFET part numbers are as widely recognized as 2N7002. Variants such as 2N7002BK, 2N7002P, and NX7002AK are heavily searched due to their use in level shifting, load switching, and signal control.
Another highly popular model is BSS138, frequently used in logic level conversion circuits, especially for I²C and low-speed digital interfaces. Variants like BSS138P, BSS138PW, and BSS138BK address different packaging and assembly requirements.
Power and Load-Switching MOSFETs
Nexperia’s PMV, BUK, and PSMN series MOSFETs are widely adopted in power management applications. Devices such as PMV50EPEA, PMV250EPEA, BUK7K6R8-40E, BUK9K17-60E, and PSMN1R4-40YLD support efficient switching in DC-DC converters, motor control circuits, and power distribution systems.
These MOSFETs are favored for their:
