Product details
Overview
NSP2201MR6T1G from onsemi is a unidirectional, low-capacitance ESD and surge protection diode array in TSOP-6 package, designed for high-speed data line protection. It delivers ±30 kV IEC 61000−4−2 contact ESD immunity, 25 A IEC 61000−4−5 lightning surge capability, 5.0 V working reverse voltage (VRWM), 8.5 V clamping voltage at 1 A, and 1.5–3.0 pF I/O-to-I/O junction capacitance - enabling robust USB 2.0 and DVI interface protection without signal integrity degradation.
For engineers reviewing the NSP2201MR6T1G datasheet, pinout, applications, or equivalent options, this device is selected for high-speed differential data lines requiring sub-10 V clamping, <3 pF inter-line capacitance, automotive-grade AEC-Q101 qualification, and integrated dual-steering + surge diode topology to eliminate discrete layout compromises.
Technical Context
The NSP2201MR6T1G implements a monolithic dual-channel unidirectional protection architecture with two I/O pins (1 and 6) referenced to ground (Pin 2) and a VCC bias input (Pin 5). Its internal structure integrates fast steering diodes and a dedicated surge-rated clamp diode, enabling transient current diversion to either VCC or GND depending on configuration - reducing clamping voltage dependence on PCB trace inductance versus discrete solutions.
It operates across −40 °C to +125 °C junction temperature, supports 500 W peak pulse power (8/20 µs), and maintains <1.0 µA reverse leakage at 5.0 V VRWM. The TSOP-6 package enables compact placement adjacent to connectors, with design-critical grounding of Pin 2 directly to low-inductance ground plane to preserve sub-10 V clamping performance under 25 A surges.

FAQ
What is the primary function of the NSP2201MR6T1G in a circuit?
The NSP2201MR6T1G functions as a unidirectional ESD and surge protection diode array that safeguards high-speed data lines - such as USB 2.0 D+ and D− or DVI TMDS pairs - from electrostatic discharge (±30 kV contact), electrical fast transients (40 A), and lightning surges (25 A, 8/20 µs). Its integrated dual-steering diode and surge clamp topology routes transient energy to VCC or ground, limiting voltage seen by downstream ICs to ≤12 V even under full-rated surge conditions. This ensures robust protection without compromising signal integrity.
Does the NSP2201MR6T1G require an external power supply to operate?
No, the NSP2201MR6T1G does not require an external power supply to perform basic ESD clamping. It operates passively using its internal PN junctions. However, Pin 5 (VP) supports optional connection to a stable 5 V VCC rail to bias the internal steering diodes - which lowers junction capacitance (improving high-frequency response) and improves clamping symmetry for both positive and negative transients. When VCC is unavailable, Pin 5 can be left unconnected, and the device uses its internal surge diode as reference - though clamping voltage rises to VRWM + VF.
How does the NSP2201MR6T1G differ from a standard TVS diode?
Unlike a standard unidirectional TVS diode, the NSP2201MR6T1G integrates two independent steering diodes and one dedicated surge clamp diode in a single TSOP-6 package. This architecture allows it to protect two data lines simultaneously while referencing to either ground (Pin 2) or VCC (Pin 5), enabling lower clamping voltage (<9 V at 1 A) and significantly lower inter-line capacitance (1.5–3.0 pF) than discrete TVS + steering diode combinations. Its design targets high-speed interfaces where capacitance and clamping precision directly impact signal fidelity and IC survivability.
Can the NSP2201MR6T1G be used for bidirectional signal lines like RS-485?
No - the NSP2201MR6T1G is explicitly a unidirectional device, optimized for DC-biased interfaces such as USB 2.0 (5 V VBUS referenced) and DVI (TMDS with common-mode offset). Its breakdown voltage (6.0 V min) and clamping behavior are specified only for positive transients relative to ground. For true bidirectional or AC-coupled lines like RS-485, a bidirectional ESD array such as NUP4201MR6T1G is required. Using NSP2201MR6T1G on bidirectional lines risks incomplete protection during negative excursions and potential forward conduction failure.
What is the significance of the "T1G" suffix in NSP2201MR6T1G?
The "T1G" suffix in NSP2201MR6T1G denotes a specific packaging and compliance configuration: "T1" indicates tape-and-reel packaging with 3,000 units per reel, and "G" certifies the device as Pb-free and RoHS-compliant per onsemi's standard marking convention. This matches the TSOP-6 (Case 318G) package and confirms adherence to environmental regulations including EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A moisture sensitivity level 1. The "G" also aligns with onsemi's generic marking diagram for Pb-free products.
