Product details
Overview
SZNUP4016P5T5G from onsemi is an ultra-low capacitance TVS diode array designed for ESD protection of high-speed data lines, featuring 0.5 pF typical junction capacitance between I/O and ground, 5.0 V reverse working voltage, and IEC 61000−4−2 ±15 kV contact ESD rating - deployed in USB 2.0 interface protection.
For engineers reviewing the SZNUP4016P5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include low-capacitance signal integrity preservation, AEC−Q101 qualification for automotive use, and SOT−953 package compatibility with high-density PCB layouts.
Technical Context
This device integrates four bidirectional TVS diodes in a single SOT−953 package, configured to protect two differential data lines (e.g., D+/D−) plus power and ground. Each channel provides clamping during ESD transients while maintaining sub-0.8 pF capacitance at 1 MHz.
It operates across −40°C to +125°C junction temperature range and meets Class 3B HBM (≥16 kV) and IEC 61000−4−2 contact (±15 kV) requirements - enabling robust protection without signal distortion in USB 2.0, Gigabit Ethernet, and display interface designs.
Key Specifications

|---|---|
| Reverse Working Voltage | 5.0 V - ensures compatibility with 3.3 V and 5 V logic rails without leakage-induced signal degradation |
| Junction Capacitance (I/O to GND) | 0.5 pF typical - preserves signal integrity up to 480 Mbps in USB 2.0 full-speed operation |
| ESD Rating (IEC 61000−4−2) | ±15 kV contact - exceeds industrial immunity requirements for end-equipment compliance |
| Breakdown Voltage | 5.5 V at 1 mA - defines clamping onset threshold for transient suppression |
| Operating Temperature Range | −40°C to +125°C - supports under-hood automotive and industrial ambient conditions |
| AEC−Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, TCT, and ESD |
Pinout & Package
SZNUP4016P5T5G is housed in a Pb−free SOT−953 (Case 527AE) package measuring 1.00 mm × 0.80 mm × 0.37 mm with 0.35 mm pitch - optimized for space-constrained high-speed routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Line 1 (e.g., USB D+) | Protected signal input/output terminal with bidirectional ESD clamp to ground |
| 2 | GND | Common reference for all TVS elements; must be low-inductance connection to system ground plane |
| 3 | I/O Line 2 (e.g., USB D−) | Second protected differential signal path, matched capacitance to Pin 1 for skew control |
| 4 | VCC / Power Rail | Optional power-line protection node; clamps transients between VCC and GND |
| 5 | No Connect (NC) | Internally unconnected; left floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low inter-pin capacitance | 0.3–0.5 pF between I/O lines - minimizes insertion loss and timing jitter in 480 Mbps USB 2.0 links |
| Dual-channel differential line protection | Independent clamping paths for D+/D− with matched electrical characteristics - maintains common-mode noise rejection |
| AEC−Q101 qualification | Validated for automotive Grade 2 temperature range and reliability stress tests - enables direct use in infotainment and ADAS interfaces |
| UL 94 V−0 flammability rating | Self-extinguishing polymer housing - satisfies safety requirements for enclosed consumer and automotive enclosures |
Applications
| USB 2.0 Interface Protection | Gigabit Ethernet PHY Protection |
|---|---|
Use Scenario: Protecting host/device USB 2.0 D+/D− differential pair and VBUS line against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional TVS array providing sub-nanosecond clamping response to divert ESD current away from transceiver ICs. Use Value: 0.5 pF capacitance prevents signal rise-time degradation, preserving eye diagram margin at 480 Mbps. | Use Scenario: Safeguarding Ethernet PHY differential pairs (TX+/TX−, RX+/RX−) on board-level connectors exposed to handling ESD. IC Role / Device Role / Timing Role: Low-capacitance transient suppressor placed adjacent to RJ45 magnetics to limit voltage overshoot during ±15 kV contact discharge. Use Value: Matched channel capacitance ensures minimal skew between differential signals, maintaining signal integrity at 1.25 Gbps. |
| Automotive Infotainment Display Link | Industrial Flat Panel Monitor Interface |
Use Scenario: ESD protection for LVDS or FPD-Link II video data lanes running from head unit to center display in vehicles. IC Role / Device Role / Timing Role: AEC−Q101-qualified TVS array placed at connector entry point to absorb cable-discharge events before reaching timing-critical SerDes. Use Value: −40°C to +125°C operation supports under-dash mounting; 0.5 pF avoids pixel clock jitter accumulation. | Use Scenario: Shielding VGA or DVI TMDS channels in commercial displays from ESD during installation or maintenance. IC Role / Device Role / Timing Role: Four-channel TVS protecting two differential pairs (clock + data) with independent ground referencing. Use Value: UL 94 V−0 housing meets enclosure fire-safety standards; low leakage (<1.0 µA) prevents DC offset drift in analog sync lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z5.0T1G | Single-channel, 0.35 pF typical capacitance, same 5.0 V VRWM but lower IEC 61000−4−2 rating (±12 kV contact) | Requires two devices for D+/D− protection; lacks integrated VCC clamp | Select when board area allows discrete placement and lower ESD margin is acceptable |
| TPD2E001DRYR | Two-channel, 0.8 pF typical capacitance, 5.5 V VRWM, supports 1.8/3.3/5 V systems | Higher capacitance may impact USB 2.0 eye opening; no AEC−Q101 qualification | Prefer for non-automotive consumer designs where footprint is constrained and AEC−Q101 not required |
Compared with ESD5Z5.0T1G and TPD2E001DRYR, SZNUP4016P5T5G uniquely delivers four-channel protection in one SOT−953 package with AEC−Q101 qualification, ±15 kV IEC 61000−4−2 rating, and 0.5 pF I/O-to-GND capacitance - making it optimal for space- and reliability-critical automotive USB and display interfaces.

FAQ
What is the primary function of the SZNUP4016P5T5G?
The SZNUP4016P5T5G is a quad-channel TVS diode array designed to protect high-speed data lines from electrostatic discharge (ESD) transients. Its core function is bidirectional clamping of voltage spikes on differential pairs (e.g., USB D+/D−) and power rails while maintaining ultra-low capacitance (0.5 pF typical) to avoid signal integrity degradation - critical for USB 2.0 and similar interfaces.
Is SZNUP4016P5T5G qualified for automotive applications?
Yes, SZNUP4016P5T5G is AEC−Q101 qualified and PPAP capable, with the "SZ" prefix indicating compliance for automotive and other applications requiring unique site and control change requirements. It operates over −40°C to +125°C and has passed stress tests including temperature cycling, high-temperature operating life, and ESD robustness per AEC−Q101 standards.
What does the "P5" in SZNUP4016P5T5G signify?
The "P5" in SZNUP4016P5T5G denotes the device's 5.0 V reverse working voltage (VRWM), which is the maximum continuous DC or peak operating voltage the device can withstand without entering breakdown. This rating ensures compatibility with standard 3.3 V and 5 V logic systems while allowing sufficient margin above normal signal swing.
How many protected channels does SZNUP4016P5T5G provide?
SZNUP4016P5T5G provides four protected terminals: two I/O pins (e.g., D+ and D−), one VCC pin for power rail protection, and one GND pin - arranged in a 5-pin SOT−953 package. The internal configuration supports dual differential line protection plus auxiliary power-line clamping, with one pin designated NC (no connect).
What is the junction capacitance specification for SZNUP4016P5T5G?
SZNUP4016P5T5G specifies 0.5 pF typical junction capacitance between each I/O pin and ground at VR = 0 V and f = 1 MHz. Between I/O pins (e.g., D+ to D−), capacitance is 0.3–0.5 pF typical - a key parameter enabling minimal signal distortion in 480 Mbps USB 2.0 applications and other high-speed differential interfaces.
