Product details
Overview
NIV1161MTWTAG from onsemi is an automotive-grade ESD protection device with integrated short-to-battery blocking MOSFETs, designed for high-speed differential data lines including USB 2.0 and LVDS. It delivers 0.65 pF typical junction capacitance, ±8 kV IEC 61000-4-2 contact ESD protection, 16 V reverse working voltage, and 1.4 Ω typical RDS(on) at 4.5 V gate drive-enabling low-signal-distortion protection in infotainment and ADAS interfaces.
For engineers reviewing the NIV1161MTWTAG datasheet, pinout, applications, or equivalent options, key selection criteria include wettable flanks for AOI compatibility, AEC-Q101 qualification, matched I/O capacitance (<1.0% mismatch), flow-through WDFNW6 package for controlled impedance routing, and dual-mode operation (steady-state signal pass-through + active STB clamping).
Technical Context
The NIV1161MTWTAG integrates two matched N-channel MOSFETs per channel to enable bidirectional signal transmission while actively blocking short-to-battery faults up to 16 VDC. Its ultra-low 0.65 pF capacitance between I/O pins and GND preserves signal integrity on 480 Mbps USB 2.0 lines, and its 5 GHz 3 dB bandwidth confirms suitability for high-frequency differential signaling.
Operation includes two distinct modes: in steady state, MOSFETs operate linearly with VGS(TH) of 0.1–1.5 V enabling compatibility with both 3.3 V and 5 V gate drives; during short-to-battery events, MOSFETs enter saturation to clamp voltage and limit termination current, leveraging body diodes for passive protection when off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Capacitance (I/O to GND) | 0.65 pF typical - minimizes signal attenuation on USB 2.0/LVDS differential pairs |
| ESD Rating (IEC 61000-4-2) | ±8 kV contact - meets automotive Level 4 ESD immunity requirements |
| Reverse Working Voltage | 16 V - supports protection against battery shorts in 12 V vehicle systems |
| RDS(on) (VGS = 4.5 V) | 1.4 Ω typical - limits signal distortion and insertion loss on high-speed data paths |
| Junction Temp Range | −55 °C to +150 °C - qualified for under-hood and infotainment module environments |
| Clamping Voltage (1 A TLP) | 26 V - limits transient overvoltage stress on downstream USB transceivers |
| Capacitance Match | <1.0% - ensures balanced impedance and common-mode noise rejection on differential lanes |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection with short-to-battery blocking applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NIV1161MTTAG | Same die, standard WDFN6 (Case 511CB); no wettable flanks | Lacks AOI-optimized terminations; suitable for non-automotive or legacy AOI processes | Select when AOI capability is not required and cost optimization is prioritized |
| NIS1161MTTAG | Non-automotive variant; identical electrical specs but not AEC-Q101 qualified | Not PPAP-capable; limited to industrial or consumer USB ports without automotive certification | Select for non-automotive designs where AEC-Q101 and PPAP are unnecessary |
Compared with NIV1161MTTAG, NIV1161MTTAG offers identical protection performance but lacks wettable flanks for AOI, while NIS1161MTTAG removes automotive qualification-making NIV1161MTWTAG the only option meeting full automotive production requirements including manufacturability verification and PPAP support.

FAQ
What is the primary function of the NIV1161MTWTAG in automotive USB 2.0 circuits?
The NIV1161MTWTAG serves as a bidirectional ESD protection device with integrated short-to-battery blocking MOSFETs for USB 2.0 differential data lines. It passes 480 Mbps signals with minimal distortion while clamping ESD transients to 26 V and limiting fault current during 16 V battery shorts. Its 0.65 pF capacitance and matched I/O pins preserve signal integrity, and the wettable flanks support AOI in automotive manufacturing. The NIV1161MTWTAG is explicitly designed for this role in infotainment and telematics modules.
Does the NIV1161MTWTAG require an external gate drive voltage?
No, the NIV1161MTWTAG does not require an external gate drive. Pin 2 (VDD) accepts a 5 V supply that powers the internal gate control circuitry, enabling automatic MOSFET biasing during normal operation and short-to-battery events. The device's low 0.1–1.5 V gate threshold voltage ensures reliable turn-on with standard 5 V USB rails. This self-contained gate drive eliminates external components and simplifies layout-confirmed in the datasheet's "Modes of Operation" section for the NIV1161MTWTAG.
Is the NIV1161MTWTAG pin-compatible with other devices in the NIx1161 family?
Yes, the NIV1161MTWTAG shares the same WDFNW6 (Case 515AK) pinout and footprint as NIV1161MTTAG and NIS1161MTTAG. All three use identical 6-pin flow-through configuration (Pin 1→4, Pin 3→6) and 2.0 mm × 2.2 mm body size. However, only the NIV1161MTWTAG includes wettable flanks; the others use standard WDFN6 (Case 511CB). This mechanical equivalence allows drop-in replacement for electrical evaluation, though AOI capability and automotive qualification differ across variants-including the NIV1161MTWTAG.
What standards does the NIV1161MTWTAG comply with for automotive ESD protection?
The NIV1161MTWTAG complies with IEC 61000-4-2 Level 4 (±8 kV contact, ±15 kV air) and ISO 10605 (automotive-specific ESD testing), as verified in its datasheet's "Features" and "Absolute Maximum Ratings" sections. It also meets AEC-Q101 stress test requirements for temperature cycling, HAST, and mechanical shock-making it PPAP-capable for automotive production. These certifications apply specifically to the NIV1161MTWTAG, not generic family-level claims.
Can the NIV1161MTWTAG be used on non-USB interfaces like LVDS or MIPI?
Yes, the NIV1161MTWTAG is validated for LVDS and other high-speed differential protocols. Its 0.65 pF capacitance, 5 GHz bandwidth, and <1.0% I/O capacitance match ensure minimal skew and signal degradation on 600 Mbps LVDS camera links. The datasheet explicitly lists "LVDS" in Typical Applications and confirms flow-through routing preserves impedance control-critical for MIPI D-PHY and similar interfaces. This capability is documented for the NIV1161MTWTAG in the Application Information section.
