Product details
Overview
SZTVS4201MR6T1G from onsemi is a unidirectional transient voltage suppressor diode array in TSOP-6 package, designed for high-speed data line protection against ESD (±30 kV contact), EFT (40 A), and lightning surges (25 A, 8/20 µs). It features 5.0 V working peak reverse voltage, 9.0 V clamping voltage at 1 A, and low 3.0–5.0 pF junction capacitance between I/O and GND - enabling USB 2.0 and DVI signal integrity preservation.
For engineers reviewing the SZTVS4201MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage under 25 A surge, sub-5 pF I/O-to-GND capacitance, AEC-Q101 qualification, TSOP-6 footprint compatibility, and ±30 kV IEC 61000-4-2 ESD robustness.
Technical Context
The SZTVS4201MR6T1G integrates five unidirectional TVS elements in a single TSOP-6 package: four I/O lines (Pins 1, 3, 4, 6) referenced to a common cathode (Pin 2, VN), with Pin 5 serving as VP (voltage protection rail). Its architecture enables simultaneous protection of differential pairs without cross-talk degradation.
It operates within −40 °C to +125 °C junction temperature range, supports 500 W peak pulse power (8/20 µs), and maintains ≤1.0 µA reverse leakage at 5.0 V VRWM - ensuring minimal loading on high-impedance data lines while delivering fast response to transients.

FAQ
What is the maximum clamping voltage of the SZTVS4201MR6T1G under a 25 A IEC 61000-4-5 surge?
The SZTVS4201MR6T1G exhibits a maximum clamping voltage of 14.0 V when subjected to a 25 A, 8/20 µs current pulse per IEC 61000-4-5, measured between any I/O pin and Pin 2 (VN). This value is specified in the Electrical Characteristics table and validated across production lots per onsemi's datasheet Rev. 3 (July 2025). The SZTVS4201MR6T1G maintains this clamping performance within its full operating temperature range.
Does the SZTVS4201MR6T1G support bi-directional signal lines like HDMI or USB-C?
No, the SZTVS4201MR6T1G is a unidirectional TVS array - each I/O pin conducts only from signal to ground (Pin 2), making it unsuitable for AC-coupled or polarity-reversing interfaces such as HDMI or USB-C without additional circuitry. For those applications, consider bi-directional alternatives like SP1003-01WTG. The SZTVS4201MR6T1G is optimized for DC-biased lines including USB 2.0, DVI, and Ethernet 10/100.
What is the junction capacitance specification between I/O pins and ground for the SZTVS4201MR6T1G?
The SZTVS4201MR6T1G has a junction capacitance of 3.0–5.0 pF measured between any I/O pin (Pins 1, 3, 4, 6) and Pin 2 (VN) at VR = 0 V and f = 1.0 MHz. This value is confirmed in the Electrical Characteristics table and critical for preserving signal integrity in 480 Mbps USB 2.0 applications. The SZTVS4201MR6T1G also specifies 1.5–3.0 pF I/O-to-I/O capacitance, reducing differential pair crosstalk.
Is the SZTVS4201MR6T1G qualified for automotive use?
Yes, the SZTVS4201MR6T1G carries the "SZ" prefix indicating AEC-Q101 qualification and PPAP capability. It is rated for operation from −40 °C to +125 °C junction temperature and tested per automotive-grade reliability standards. The SZTVS4201MR6T1G is deployed in automotive infotainment display interfaces and ADAS camera links where ESD and surge immunity are mandated by OEM specifications.
What is the role of Pin 5 (VP) on the SZTVS4201MR6T1G?
Pin 5 (VP) on the SZTVS4201MR6T1G is an optional voltage protection rail used to bias the internal TVS structure for tighter clamping control in specialized configurations. It is not required for standard unidirectional operation - the device functions fully with only Pins 1–4 (I/O), Pin 2 (VN), and Pin 6 (I/O) connected. The SZTVS4201MR6T1G datasheet confirms VP is unused in default USB/DVI protection layouts.
