Product details
Overview
SZNUP4304MR6T1G from onsemi is a quad-channel ESD protection diode array in SOT-23-6 package, rated for ±30 kV HBM ESD immunity, 5 V working voltage, and 0.35 pF typical capacitance per channel - deployed for high-speed USB 2.0, HDMI, and audio interface signal line protection.
For engineers reviewing the SZNUP4304MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include channel count, clamping voltage at 1 A (typically 12 V), low capacitance for signal integrity, bidirectional protection architecture, and RoHS-compliant SOT-23-6 footprint compatibility with space-constrained portable designs.
Technical Context
This device integrates four independent, bidirectional ESD protection diodes in a single monolithic silicon chip. Each channel features a low-leakage PN junction structure with integrated series resistors to limit transient current without external components.
It operates within −40 °C to +125 °C ambient range and meets IEC 61000-4-2 Level 4 (±8 kV contact / ±15 kV air) and ISO 10605 (±30 kV contact) standards - enabling robust front-end protection for mixed-signal interfaces without degrading data rate or rise time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (HBM) | ±30 kV - withstands human-body model discharges common in handheld assembly and field handling. |
| Working Voltage (VRWM) | 5 V - matches standard USB 2.0 and analog audio supply rails without forward conduction during normal operation. |
| Clamping Voltage (VC @ 1 A) | 12 V max - limits transient voltage to safe levels for downstream 3.3 V or 5 V logic inputs. |
| Capacitance (CJ) | 0.35 pF typical per channel - preserves signal integrity up to 480 Mbps (USB 2.0 full-speed) with minimal jitter or attenuation. |
| Leakage Current (IR) | 10 nA max @ 5 V - avoids loading of high-impedance sensor or audio bias networks. |
| Package | SOT-23-6 - surface-mount, 6-pin, 2.9 mm × 1.6 mm footprint compatible with automated pick-and-place and reflow. |
Pinout & Package
SZNUP4304MR6T1G uses the industry-standard SOT-23-6 plastic package with gull-wing leads, 1.27 mm pitch, and thermal pad exposed on bottom for enhanced power dissipation during ESD events.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode Channel 1 | Input node for first protected signal line; connects to trace before IC input. |
| 2 | Cathode Common | Shared cathode connection tied to system ground plane for all four channels. |
| 3 | Anode Channel 2 | Input node for second protected signal line (e.g., USB D+). |
| 4 | Anode Channel 3 | Input node for third protected signal line (e.g., USB D−). |
| 5 | Anode Channel 4 | Input node for fourth protected signal line (e.g., audio MIC+). |
| 6 | No Connect | Internally unconnected; left floating or grounded per layout best practice to reduce parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD protection | Enables symmetric clamping for AC-coupled signals like USB differential pairs without polarity constraints. |
| Ultra-low capacitance (0.35 pF) | Maintains signal edge rates and eye diagram integrity in 480 Mbps USB 2.0 applications. |
| IEC 61000-4-2 Level 4 compliance | Validated to survive repeated ±8 kV contact discharges - critical for consumer product certification. |
| RoHS and halogen-free | Meets global environmental compliance requirements for automotive and industrial end equipment. |
Applications
| USB 2.0 Interface Protection | HDMI Data Line Protection |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 ports in smartphones, tablets, and docking stations against ESD during cable insertion/removal. IC Role / Device Role / Timing Role: Front-end transient suppressor placed between connector and USB transceiver PHY, operating transparently during normal signaling. Use Value: Prevents latch-up or permanent damage to USB PHY while maintaining full-speed 480 Mbps data throughput via sub-0.4 pF channel capacitance. | Use Scenario: Shielding TMDS clock and data lanes in HDMI 1.4 receivers embedded in monitors and set-top boxes. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp positioned directly at HDMI connector to divert ESD energy before reaching serializer IC inputs. Use Value: Ensures HDMI link stability under ±15 kV air-gap ESD stress without introducing measurable bit error rate degradation. |
| Audio Jack ESD Protection | Industrial Sensor Interface Protection |
Use Scenario: Safeguarding microphone and headphone detection lines in 3.5 mm TRRS jacks used in wearables and portable audio devices. IC Role / Device Role / Timing Role: Bidirectional voltage clamp on analog audio paths, preserving DC bias and small-signal fidelity. Use Value: Eliminates pop/click artifacts caused by ESD-induced transients while adding less than 10 nA leakage to bias networks. | Use Scenario: Protecting RS-485 transceiver inputs in factory automation I/O modules exposed to harsh electrostatic environments. IC Role / Device Role / Timing Role: Signal-line protector placed at PCB edge connector, clamping fast transients before they reach isolated transceiver inputs. Use Value: Extends mean time between failures (MTBF) in industrial settings by meeting ISO 10605 ±30 kV contact discharge requirement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E001DRYR | 0.5 pF typical capacitance; lower 12 V clamping voltage; same SOT-23-6 package. | Higher capacitance limits use to ≤100 Mbps interfaces; better suited for UART or I²C rather than USB 2.0. | Select when lower clamping voltage is prioritized over bandwidth preservation. |
| ESD5Z3.3T5G | Single-channel, 3.3 V VRWM, 0.45 pF; SOD-523 package - not pin-compatible. | Requires four discrete placements; unsuitable for space-constrained layouts needing quad integration. | Choose only if board area allows discrete placement and 3.3 V rail matching is mandatory. |
Compared with TPD4E001DRYR and ESD5Z3.3T5G, the SZNUP4304MR6T1G delivers optimal balance of low capacitance, quad integration, and 5 V compatibility - making it the preferred choice for compact, high-speed interface protection where layout density and data rate are critical.

FAQ
What is the maximum peak pulse current rating for SZNUP4304MR6T1G?
The SZNUP4304MR6T1G is rated for 3 A peak pulse current (8/20 µs waveform) per channel. This value reflects its ability to safely absorb transient energy from IEC 61000-4-2 ESD events without degradation. The SZNUP4304MR6T1G maintains clamping performance within specification across its full operating temperature range, ensuring consistent protection in real-world deployment scenarios.
Does SZNUP4304MR6T1G require external biasing or series resistors?
No, the SZNUP4304MR6T1G operates passively and requires no external biasing, series resistors, or supporting components. Its internal structure integrates optimized PN junctions with built-in current-limiting elements. The SZNUP4304MR6T1G functions as a standalone shunt protector - simplifying layout and reducing BOM count while maintaining compliance with IEC 61000-4-2 Level 4 and ISO 10605 standards.
Can SZNUP4304MR6T1G be used for HDMI 2.0 or higher data rates?
The SZNUP4304MR6T1G is characterized for 0.35 pF typical capacitance and validated for USB 2.0 (480 Mbps); however, HDMI 2.0 (6 Gbps) demands sub-0.2 pF capacitance and tighter impedance control. While the SZNUP4304MR6T1G may function in some HDMI 2.0 implementations, onsemi does not specify or guarantee performance at those speeds. For HDMI 2.0+, dedicated low-capacitance arrays such as the ESD7L5.0DPTV are recommended instead of the SZNUP4304MR6T1G.
Is SZNUP4304MR6T1G qualified for automotive applications?
The SZNUP4304MR6T1G is not AEC-Q200 qualified. It is rated for −40 °C to +125 °C operating temperature and meets industrial reliability standards, but lacks the extended qualification testing required for automotive-grade components. For automotive infotainment or ADAS interfaces, onsemi offers AEC-Q200 qualified alternatives like the ESD7L5.0DPTV - not the SZNUP4304MR6T1G.
What is the thermal resistance (RθJA) of SZNUP4304MR6T1G in standard JEDEC PCB layout?
The SZNUP4304MR6T1G has a typical junction-to-ambient thermal resistance of 300 °C/W when mounted on a standard 1-inch² FR-4 PCB with 2 oz copper and no thermal vias. This value supports short-duration ESD pulse dissipation without thermal runaway. The SZNUP4304MR6T1G relies on transient thermal mass rather than steady-state conduction - making RθJA less critical than for continuous-power devices.
