Product details
Overview
SZNUP3112UPMUTAG from onsemi is an ultra-low-capacitance ESD protection diode array in a 6-pin UDFN package, designed to protect three high-speed data lines (D1–D3) and a VCC power line against IEC61000-4-2 Level 4 ESD events (±14 kV contact). It delivers 0.7 pF typical capacitance per data line, 5.2 V minimum breakdown voltage for signal pins, and 15 V clamping for VCC - making it suitable for USB 2.0 high-speed interfaces in space-constrained mobile designs.
For engineers reviewing the SZNUP3112UPMUTAG datasheet, pinout, applications, or equivalent options, key selection criteria include sub-1 pF line-to-GND capacitance, common-anode quad-channel architecture, AEC-Q101 qualification, 1.6 × 1.6 mm UDFN footprint, and verified IEC61000-4-2 Level 4 ESD robustness.
Technical Context
The SZNUP3112UPMUTAG implements a common-anode quad-diode array with three unidirectional signal-line diodes (D1–D3) and one VCC-supply diode, all sharing a single GND connection. Its low-leakage design maintains ≤1.0 µA reverse current at rated VRWM, enabling compatibility with battery-powered systems.
Clamping behavior is characterized under IEC61000-4-2 8 kV contact discharge, with documented oscilloscope waveforms showing voltage suppression across the full pulse duration. The device operates from −40°C to +125°C and supports reflow soldering up to 260°C for 10 seconds.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NUP3112UPMUTAG | 0.7 pF, 5.2 V D1–D3 BR, 15 V VCC clamp, UDFN6 | Optimized for USB 2.0 + VCC rail protection in space-limited layouts | Preferred for new designs requiring AEC-Q101 and IEC61000-4-2 Level 4 compliance |
| TPD2E001DRYR | 1.0 pF, 5.5 V BR, no VCC clamp, SOT-5X3 | Lacks integrated VCC protection - requires external TVS for power rail | Acceptable where board area allows separate VCC protection and 1 pF loading is tolerable |
Compared with TPD2E001DRYR and NUP4202MR6T1G, the SZNUP3112UPMUTAG uniquely integrates VCC clamping in the same ultra-low-capacitance package, reducing BOM count and PCB real estate while meeting automotive-grade reliability standards.

FAQ
What is the maximum operating temperature range for the SZNUP3112UPMUTAG?
The SZNUP3112UPMUTAG is rated for operation from −40°C to +125°C junction temperature, supporting deployment in automotive cabin environments and industrial edge nodes where ambient temperatures exceed 85°C. This rating is confirmed in the Absolute Maximum Ratings table of the official datasheet (Rev. 2, October 2017), and the device maintains specified clamping performance across this full range.
Does the SZNUP3112UPMUTAG provide bidirectional or unidirectional ESD protection?
The SZNUP3112UPMUTAG provides unidirectional protection for its D1–D3 signal lines (cathode-to-line configuration) and unidirectional clamping for the VCC pin (anode-to-rail). This architecture is optimized for DC-biased interfaces like USB 2.0 and SIM card lines, where transients occur relative to GND. Bidirectional capability is not supported - reverse polarity events require external design considerations.
How does the SZNUP3112UPMUTAG differ from the standard NUP3112UPMU variant?
The SZNUP3112UPMUTAG includes the "SZ" prefix indicating automotive-grade qualification per AEC-Q101, PPAP capability, and unique site/control change tracking - whereas the NUP3112UPMU is intended for commercial applications. Both share identical electrical specs and package, but only the SZNUP3112UPMUTAG is approved for automotive use cases such as infotainment and telematics modules.
Can the NC pins (pins 5 and 6) on the SZNUP3112UPMUTAG be connected to ground?
Pins 5 and 6 are internally unconnected (NC) and may be left floating or tied to GND per PCB layout best practices - grounding them improves thermal dissipation and reduces parasitic antenna effects without affecting device function. The official datasheet (Figure "PIN CONNECTIONS") confirms no internal bond wire exists for these terminals, and onsemi's mounting guidelines recommend GND connection for mechanical stability.
Is the SZNUP3112UPMUTAG compatible with lead-free reflow processes?
Yes, the SZNUP3112UPMUTAG is Pb-free and qualified for standard lead-free reflow profiles, with a maximum lead solder temperature of 260°C for 10 seconds. Its UDFN6 package (Case 517AP) complies with IPC/JEDEC J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to assembly. Full process details are in onsemi's Soldering and Mounting Techniques Reference Manual (SOLDERRM/D).
