Product details
Overview
SZNSP4201MR6T1G from onsemi is a unidirectional ESD and surge protection diode array in TSOP-6 package, rated for 5.0 V working reverse voltage, 14.0 V clamping voltage at 25 A (8/20 µs), and 3.0–5.0 pF junction capacitance between I/O and GND - deployed to safeguard USB 2.0 data lines against ±30 kV contact ESD per IEC 61000−4−2.
For engineers reviewing the SZNSP4201MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage under high surge current, sub-5 pF signal-line capacitance, AEC-Q101 qualification for automotive interfaces, and TSOP-6 footprint compatibility with high-density USB/DVI routing.
Technical Context
The SZNSP4201MR6T1G integrates five unidirectional TVS diodes in a single TSOP-6 package: four I/O pins (1, 3, 4, 6) referenced to GND (Pin 2), with VCC (Pin 5) providing bias for internal clamping paths. It operates as a rail-to-rail clamp without series impedance, enabling direct placement on differential or single-ended high-speed lines.
Its clamping behavior follows a defined 8/20 µs pulse response, delivering 9.0 V clamping at 1 A and rising to 14.0 V at 25 A IEC 61000−4−5 surge level, while maintaining ≤1.0 µA leakage at 5.0 V VRWM - critical for preserving signal integrity in battery-powered USB peripherals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Peak Reverse Voltage | 5.0 V - sets maximum continuous DC bias before leakage rises; matches USB 2.0 VBUS and D+/D− common-mode range. |
| Clamping Voltage @ 25 A | 14.0 V - peak voltage seen by protected IC during full IEC 61000−4−5 lightning surge; stays below typical 16 V I/O absolute max ratings. |
| Junction Capacitance (I/O–GND) | 3.0–5.0 pF - ensures minimal signal distortion on 480 Mbps USB 2.0 channels; measured at 1 MHz, 0 V bias. |
| ESD Withstand (Contact) | ±30 kV - exceeds IEC 61000−4−2 Level 4 by 2×; enables robust front-panel port protection without external spark gaps. |
| Surge Current Rating | 25 A (8/20 µs) - supports industrial-grade lightning immunity per IEC 61000−4−5; validated on all I/O-to-GND paths. |
| AEC-Q101 Qualified | Yes - certified for automotive infotainment and ADAS display interfaces requiring extended temperature operation (−40°C to +125°C). |
Pinout & Package
Package: TSOP-6 (Case 318G), 3.00 × 1.50 × 0.90 mm, 0.95 mm pitch, Pb-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O | Protected signal line - connects directly to USB D+, DVI TMDS+, or Ethernet TX+; clamped to GND via internal diode. |
| 2 | GND | System ground reference - low-inductance return path for all clamping currents; must be tied to clean local ground plane. |
| 3 | I/O | Protected signal line - used for complementary data pair (e.g., USB D−, DVI TMDS−); shares same clamping architecture as Pin 1. |
| 4 | I/O | Protected signal line - supports third channel (e.g., DVI clock, auxiliary USB ID line); independent clamping path to GND. |
| 5 | VCC | Bias supply input - enables active clamping mode; must be connected to stable 3.3–5.0 V rail; not floating. |
| 6 | I/O | Protected signal line - fourth I/O channel; allows single-device protection of multi-lane interfaces like dual USB or DVI + clock. |
Key Features
| Feature | Design Value |
|---|---|
| Low clamping voltage at high current | 14.0 V at 25 A ensures downstream PHY ICs remain within safe operating area during lightning surges. |
| Ultra-low I/O-to-GND capacitance | 3.0–5.0 pF preserves signal rise/fall times on 480 Mbps USB 2.0 links without added jitter or eye closure. |
| AEC-Q101 qualification | Validated for automotive display modules and infotainment head units operating from −40°C to +125°C junction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD and surge protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Bi-directional, 5.5 V VRWM, 12.5 V clamping @ 25 A, 1.5 pF I/O–I/O capacitance | Supports AC-coupled lines (e.g., HDMI) but lacks VCC-assisted clamping; lower capacitance suits >1 Gbps interfaces | Choose for bidirectional signal lines where VCC bias is unavailable or where sub-2 pF is mandatory |
| SP1001-01UTG | Unidirectional, 5.0 V VRWM, 15.0 V clamping @ 25 A, 5.5 pF I/O–GND, SOT-553 package | Same electrical specs but smaller 1.6 × 1.6 mm footprint; no VCC pin - simpler layout but higher clamping at peak current | Choose when PCB space is constrained and VCC bias cannot be routed; verify 15.0 V clamping margin with downstream IC |
Compared with TPD2E001DRYR and SP1001-01UTG, the SZNSP4201MR6T1G uniquely combines VCC-enhanced low clamping (14.0 V), AEC-Q101 qualification, and four-channel I/O protection in TSOP-6 - making it optimal for automotive USB/DVI where bias rail availability and temperature robustness are prioritized over minimum capacitance.

FAQ
What is the clamping voltage of SZNSP4201MR6T1G at 25 A surge current?
The SZNSP4201MR6T1G delivers a maximum clamping voltage of 14.0 V at 25 A (8/20 µs waveform) on any I/O-to-GND path, as specified in its Electrical Characteristics table. This value is measured under standardized IEC 61000−4−5 test conditions and ensures protected ICs remain within safe voltage margins during lightning-surge events. The SZNSP4201MR6T1G maintains this performance across its full operating temperature range.
Does SZNSP4201MR6T1G require a VCC connection to function?
Yes, SZNSP4201MR6T1G requires Pin 5 (VCC) to be connected to a stable 3.3 V or 5.0 V supply for proper unidirectional clamping operation. Without VCC, the internal bias network cannot activate the low-impedance clamping path, resulting in degraded surge suppression. The SZNSP4201MR6T1G datasheet specifies VCC as mandatory for achieving the rated 14.0 V clamping at 25 A.
Is SZNSP4201MR6T1G suitable for USB 2.0 high-speed data lines?
Yes, SZNSP4201MR6T1G is explicitly designed for USB 2.0 protection, with 3.0–5.0 pF I/O-to-GND capacitance and verified signal integrity up to 480 Mbps. Its low clamping voltage and fast response preserve eye diagram margins, and its inclusion in onsemi's "Typical Applications" section confirms deployment on USB D+/D− lines. The SZNSP4201MR6T1G meets USB-IF ESD robustness recommendations without compromising timing.
What is the package type and dimensions of SZNSP4201MR6T1G?
SZNSP4201MR6T1G uses the TSOP-6 package (Case 318G), measuring 3.00 mm × 1.50 mm × 0.90 mm with 0.95 mm lead pitch. It is Pb-free and RoHS compliant, with markings including "42M" and a microdot or "G" indicator for lead-free status. The SZNSP4201MR6T1G mechanical drawing is documented in onsemi's 98ASB14888C specification.
How does SZNSP4201MR6T1G differ from generic TVS diodes in surge protection?
Unlike discrete TVS diodes, SZNSP4201MR6T1G integrates four matched unidirectional clamps plus VCC bias in one TSOP-6 package, enabling simultaneous protection of multiple high-speed lines with consistent clamping behavior. It offers guaranteed 3.0–5.0 pF capacitance, AEC-Q101 qualification, and IEC 61000−4−2/−4−5 compliance out-of-box - whereas generic TVS require manual matching and lack system-level validation. The SZNSP4201MR6T1G eliminates layout complexity for multi-lane interfaces.
