Product details
Overview
SZNSP2201MR6T1G from onsemi is a unidirectional, low-capacitance surge protection diode array in TSOP-6 package, designed to protect two high-speed data lines (e.g., USB D+/D−) against ESD (±30 kV contact), EFT (40 A), and lightning surges (25 A, 8/20 µs). It features 5.0 V working reverse voltage, 8.5 V clamping at 1 A, 3.0–5.0 pF I/O-to-GND capacitance, and AEC-Q101 qualification for automotive applications.
For engineers reviewing the SZNSP2201MR6T1G datasheet, pinout, applications, or equivalent options, this device is selected for high-speed interface protection where low clamping voltage, minimal signal distortion, and automotive-grade reliability are critical - especially in USB 2.0, DVI, and flat-panel display interfaces.
Technical Context
The SZNSP2201MR6T1G integrates two steering diodes and one surge-rated protection diode in a single TSOP-6 package. Its unidirectional architecture references protected I/O lines to either ground (pin 2) or VCC (pin 5), enabling flexible clamping to fixed rails during transients.
Clamping behavior is defined by VRWM = 5.0 V, VBR = 6.0 V (at 1 mA), and VC = 8.5 V @ 1 A (8/20 µs), with junction capacitance tightly controlled at 3.0–5.0 pF (I/O-to-GND) to preserve signal integrity up to 480 Mbps. It operates across −40 °C to +125 °C and meets IEC 61000-4-2, -4-4, and -4-5 standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Reverse Voltage | 5.0 V - Sets maximum continuous DC operating voltage before leakage rises; matches USB 2.0 VBUS and logic-level I/O rails. |
| Clamping Voltage @ 1 A | 8.5 V - Maximum voltage seen by protected IC during 1 A transient; ensures safe margin below typical 12 V I/O absolute max ratings. |
| Junction Capacitance (I/O–GND) | 3.0–5.0 pF - Enables use on 480 Mbps USB 2.0 without measurable signal rise-time degradation or insertion loss. |
| ESD Withstand (Contact) | ±30 kV - Exceeds IEC 61000-4-2 Level 4 by 2×, supporting robust system-level ESD immunity without external shielding. |
| Surge Current (8/20 µs) | 25 A - Sustains lightning-induced surges per IEC 61000-4-5, protecting downstream PHYs and controllers in industrial/commercial ports. |
| Operating Temperature | −40 °C to +125 °C - Validated for under-hood automotive modules and industrial displays requiring extended thermal range. |
| AEC-Q101 Qualified | Yes - Confirmed reliability for automotive electronics including infotainment USB ports and display interfaces. |

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 |
|---|---|---|---|
| NUP4201MR6T1G | Same TSOP-6 package, but bidirectional; VRWM = 5.0 V, VC = 14.5 V @ 1 A, CJ = 13 pF (I/O–GND) | Higher capacitance limits use to ≤12 Mbps interfaces; suitable for legacy USB 1.1 or low-speed I²C, not USB 2.0. | Select when bidirectional clamping is required and speed is secondary to cost or availability. |
| SP1001-01UTG | TSOP-6, unidirectional, VRWM = 5.0 V, VC = 12 V @ 1 A, CJ = 0.6 pF (I/O–GND), lower peak power (300 W) | Lower capacitance enables >5 Gbps interfaces (e.g., USB 3.2 Gen 1), but reduced 25 A surge rating limits lightning robustness. | Select for ultra-high-speed designs where 25 A surge immunity is not required and sub-1 pF capacitance is mandatory. |
Compared with NUP4201MR6T1G and SP1001-01UTG, SZNSP2201MR6T1G uniquely balances 25 A surge capability, 8.5 V low clamping, and 3–5 pF capacitance - making it optimal for USB 2.0 and DVI applications demanding both speed and ruggedness.

FAQ
What is the maximum clamping voltage of SZNSP2201MR6T1G at 25 A surge current?
The SZNSP2201MR6T1G clamps to 12 V at 25 A (8/20 µs pulse), as specified in its Electrical Characteristics table. This value ensures protected ICs remain within safe operating voltage margins during lightning-surge events, and is validated per IEC 61000-4-5 testing. The clamping curve is monotonic and well-characterized up to 30 A in onsemi's Figure 2.
Can SZNSP2201MR6T1G be used for bidirectional signal lines like USB D+ and D−?
Yes - although SZNSP2201MR6T1G is unidirectional, its internal configuration (two I/O pins referenced to VN and optionally VP) allows symmetric protection of differential pairs such as USB D+/D−. When VP is tied to VCC, positive transients clamp to VCC + VF and negative transients clamp to ground, achieving effective bidirectional behavior without requiring a bidirectional device.
Is SZNSP2201MR6T1G compatible with lead-free reflow soldering processes?
Yes - SZNSP2201MR6T1G is Pb-free and rated for lead-free reflow with a maximum lead solder temperature of 260 °C for 10 seconds, per its Maximum Ratings table. Its TSOP-6 package (Case 318G) is qualified for standard JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), eliminating bake requirements prior to assembly.
How does the 3.0–5.0 pF junction capacitance of SZNSP2201MR6T1G affect USB 2.0 signal integrity?
The 3.0–5.0 pF I/O-to-GND capacitance of SZNSP2201MR6T1G introduces negligible loading on USB 2.0 signals: at 480 Mbps (240 MHz fundamental), capacitive reactance remains >130 Ω, preserving impedance matching and eye diagram opening. Onsemi's Application Note AND8308/D confirms no measurable rise-time degradation or jitter increase in validated USB 2.0 layouts using SZNSP2201MR6T1G.
What is the role of Pin 5 (VP) in SZNSP2201MR6T1G, and is it mandatory to connect?
Pin 5 (VP) provides a positive reference for biasing the internal steering diodes. Connecting VP to VCC reduces diode capacitance and improves clamping symmetry for positive transients. It is optional: if left open, the device operates in "Option 3" mode using the internal surge diode as reference (VC ≈ VRWM + VF), but capacitance increases slightly and clamping becomes asymmetric. For USB 2.0, onsemi recommends connecting VP to 5 V.
