Product details
Overview
SZNUP2301MW6T1G from onsemi is a low-capacitance dual-channel ESD protection diode array in SC-88 package, rated for 70 V reverse voltage, 2.0 pF max inter-I/O capacitance, and IEC 61000-4-2 Level 4 (8 kV contact / 15 kV air) compliance - deployed for high-speed data line protection in I²C buses and microcontroller inputs.
For engineers reviewing the SZNUP2301MW6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include inter-pin capacitance ≤2.0 pF, bidirectional ESD clamping to VP/VN rails, AEC-Q101 qualification, and SC-88 footprint compatibility with space-constrained board layouts.
Technical Context
This device integrates two independent bidirectional ESD protection diodes in a single SC-88 package, each with 70 V reverse breakdown voltage and sub-1.25 V forward voltage at 150 mA. It routes transients from either I/O line to VP (positive rail) or VN (ground rail), enabling flexible system-level clamping without external biasing.
The diode array supports JEDEC JESD22-A114 (HBM Class 3B) and JESD22-A115 (MM Class C) standards, and its 1.0–2.0 pF inter-I/O capacitance ensures minimal signal distortion on high-speed lines up to 100 Mbps - critical for T1/E1, HDSL, and I²C interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 Vdc - sets maximum working voltage before breakdown on protected data lines |
| Inter-I/O Capacitance (CD) | 1.0–2.0 pF @ 1 MHz - preserves signal integrity on high-speed serial buses like I²C |
| ESD Rating (IEC 61000-4-2) | 8 kV contact / 15 kV air - meets industrial and automotive Level 4 immunity requirements |
| Forward Voltage (VF) | 1.25 V max @ 150 mA - ensures low clamping voltage during transient events |
| Junction Temp Range | −55 °C to +150 °C - supports operation in under-hood automotive and industrial environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements |
Pinout & Package
SC-88 package (Case 419B, 2.00 × 1.25 × 0.90 mm, 0.65 mm pitch) with six terminals. Pin 1 = VN (ground reference), Pin 2 = CH1 (I/O channel 1), Pin 3 = VP (positive rail), Pin 4 = N/C, Pin 5 = CH2 (I/O channel 2), Pin 6 = N/C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VN | Ground reference node for ESD current return path |
| 2 | CH1 | Protected I/O line 1 - bidirectionally clamped between VP and VN |
| 3 | VP | Positive supply rail connection for clamping transients toward power domain |
| 4 | N/C | No internal connection - must be left floating or grounded per layout guidelines |
| 5 | CH2 | Protected I/O line 2 - functionally identical to CH1, electrically isolated |
| 6 | N/C | No internal connection - must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional ESD clamping | Routes transients from CH1 or CH2 to either VP or VN - eliminates need for separate positive/negative rail clamps |
| Low inter-I/O capacitance | Max 2.0 pF enables use on 100+ Mbps digital buses without signal degradation |
| AEC-Q101 qualification | Validated for automotive applications including engine control, infotainment, and ADAS sensor interfaces |
| Single-package dual-line protection | Replaces two discrete TVS diodes - reduces BOM count and PCB area by ~40% vs. discrete solutions |
| Pb-free SC-88 packaging | RoHS-compliant 2.00 × 1.25 mm footprint compatible with standard reflow profiles (260 °C peak) |
Applications
| I²C Bus Protection | Microcontroller GPIO Protection |
|---|---|

IC Role / Device Role / Timing Role: Low-leakage (≤2.5 nA @ 70 V) clamping diode that remains transparent during normal operation. Use Value: Enables reliable operation across −55 °C to +150 °C ambient without derating - validated per AEC-Q101 temperature cycling. |

Use Scenario: Secondary-side ESD protection for transformer-coupled T1/E1 telecom interface circuits in base station line cards. IC Role / Device Role / Timing Role: High-speed clamp placed after isolation transformer to absorb fast transients before reaching PHY IC. Use Value: 8 kV contact discharge rating ensures compliance with GR-1089-CORE telecom immunity requirements. |
Use Scenario: Shielding analog video lines (e.g., CVBS, RGB) in automotive display modules from ESD coupling via cables or connectors. IC Role / Device Role / Timing Role: Low-capacitance shunt element that avoids signal attenuation or ghosting in DC-coupled video paths. Use Value: 1.6–3.0 pF capacitance to ground minimizes high-frequency roll-off - maintains >5 MHz bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5Z3.3T5G | Single-channel, 3.3 V working voltage, 0.5 pF typical capacitance - lower clamping voltage but no VP rail connection | Best suited for low-voltage logic (1.8–3.3 V) where rail-to-rail clamping isn't required | Select when protecting only one line with tighter voltage margin and ultra-low capacitance priority |
| TPD2E001DRYR | Dual-channel, 5.5 V working voltage, 12 pF inter-I/O capacitance - higher capacitance, integrated 100 Ω series resistors | Designed for USB 2.0 and HDMI hot-plug scenarios requiring series impedance matching | Choose for differential high-speed interfaces needing built-in termination, not for general-purpose I/O protection |
Compared with ESD5Z3.3T5G and TPD2E001DRYR, the SZNUP2301MW6T1G uniquely supports bidirectional clamping to both VP and VN rails at 70 V rating, delivers lowest inter-I/O capacitance among dual-channel automotive-qualified options, and enables flexible grounding schemes without sacrificing ESD robustness.

FAQ
What is the primary function of the SZNUP2301MW6T1G?
The SZNUP2301MW6T1G is a dual-channel, low-capacitance ESD protection diode array designed to safeguard two high-speed data lines from electrostatic discharge. It provides bidirectional clamping between each I/O pin and either VP (positive rail) or VN (ground), with 70 V reverse voltage rating and ≤2.0 pF inter-I/O capacitance - making it ideal for I²C, T1/E1, and microcontroller interface protection. The SZNUP2301MW6T1G is explicitly qualified to AEC-Q101 for automotive use.
Does the SZNUP2301MW6T1G require external biasing to operate?
No, the SZNUP2301MW6T1G operates passively without external bias. Its internal diode architecture enables automatic clamping from either CH1 or CH2 to VP or VN depending on transient polarity - no external voltage or control signals are needed. Pins 4 and 6 are unconnected (N/C) and must remain floating or grounded per layout guidance in the onsemi datasheet. The SZNUP2301MW6T1G functions immediately upon installation in the signal path.
How does the SZNUP2301MW6T1G differ from the standard NUP2301MW6T1G?
The SZNUP2301MW6T1G carries the "SZ" prefix indicating automotive-specific manufacturing controls, AEC-Q101 qualification, and PPAP capability - whereas the NUP2301MW6T1G is intended for commercial/industrial use. Both share identical electrical specs, SC-88 package, pinout, and thermal characteristics, but only the SZNUP2301MW6T1G is certified for automotive applications per onsemi's documentation. The SZNUP2301MW6T1G is the appropriate choice for automotive ECUs and ADAS modules.
Can the SZNUP2301MW6T1G protect against IEC 61000-4-2 Level 4 ESD events?
Yes, the SZNUP2301MW6T1G is rated for IEC 61000-4-2 Level 4: 8 kV contact discharge and 15 kV air discharge. This rating is verified per onsemi's datasheet Rev. 6 (September 2025) and applies to both CH1 and CH2 channels when properly routed to VP and VN with a low-ESR 0.2 µF ceramic bypass capacitor between those rails. The SZNUP2301MW6T1G meets this standard without derating across its full operating temperature range.
What is the maximum allowable junction temperature for continuous operation of the SZNUP2301MW6T1G?
The SZNUP2301MW6T1G has a specified junction temperature range of −55 °C to +150 °C, confirmed in the Absolute Maximum Ratings table of the official datasheet. Continuous operation at +150 °C is permitted provided the thermal resistance junction-to-ambient (RJA) of 625 °C/W is respected in the final PCB layout - typically achieved using ≥2 cm² of 2-oz copper pour connected to VN and VP pins. The SZNUP2301MW6T1G maintains full ESD performance across this entire range.
