Product details
Overview
SRV05-4MR6T1G from onsemi is a unidirectional 4-channel ESD protection diode array in TSOP-6 package, designed for high-speed data line protection with 5 V working voltage, <5 pF capacitance, and 12.5 V clamping voltage at 1 A pulse. It safeguards USB 2.0, DVI, and Ethernet 10/100 interfaces against IEC61000-4-2 ±8 kV contact ESD events.
For engineers reviewing the SRV05-4MR6T1G datasheet, pinout, applications, or equivalent options, key selection criteria include low clamping voltage under 17.5 V at 5 A, junction capacitance ≤5.0 pF between I/O and GND, compliance with IEC61000-4-4 (40 A EFT) and IEC61000-4-5 (12 A lightning), and TSOP-6 footprint compatibility with SOT-23-6 and SC-74.
Technical Context
The SRV05-4MR6T1G integrates four steering diodes and one TVS diode in a single TSOP-6 package to route transients from I/O pins (1,3,4,6) to reference pins (2 = VN, 5 = VP). Its unidirectional architecture enables clamping to VCC or ground depending on configuration-Option 1 uses pin 5 as VCC reference, Option 3 leaves pin 5 open for TVS-based referencing.
Clamping behavior follows VC = VF + VTVS, where VF is steering diode forward voltage and VTVS is TVS breakdown (~6.0 V). Measured clamping is 12.5 V at 1 A and 17.5 V at 5 A (8×20 µs pulse), with junction capacitance of 3.0–5.0 pF (I/O-to-GND) ensuring minimal signal distortion on USB/DVI lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 5.0 V - Matches standard USB 2.0 and DVI power rail levels without overvoltage stress. |
| Clamping Voltage @ 1 A | 12.5 V - Limits transient voltage seen by protected IC during low-energy ESD events. |
| Clamping Voltage @ 5 A | 17.5 V - Maintains safe voltage margin under higher-energy IEC61000-4-2 contact discharge. |
| Junction Capacitance | 3.0–5.0 pF (I/O-to-GND) - Enables use on >480 Mbps USB 2.0 differential pairs without signal integrity loss. |
| ESD Rating | ±8 kV contact per IEC61000-4-2 - Certified protection level for handheld device interface ports. |
| Peak Pulse Power | 300 W (8×20 µs) - Sustains transient energy from lightning surges (IEC61000-4-5, 12 A). |
| Leakage Current | 5.0 µA @ 5 V - Negligible standby current draw on data lines, preserving low-power system operation. |
Pinout & Package
TSOP-6 package (Case 318G), 1.5 mm × 3.0 mm × 0.95 mm body, Pb-free, RoHS-compliant, UL 94 V-0 rated. Footprint compatible with SOT-23-6 and SC-74.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I/O Line 1 | Protected high-speed data line (e.g., USB D+); connected to internal steering diode anode. |
| 2 | VN (Ground Reference) | Common cathode connection for all four steering diodes; must be tied directly to low-inductance ground plane. |
| 3 | I/O Line 2 | Protected high-speed data line (e.g., USB D−); same internal structure as Pin 1. |
| 4 | I/O Line 3 | Third protected line (e.g., DVI TMDS+); shares clamping path via internal TVS when referenced to Pin 5. |
| 5 | VP (VCC Reference) | Positive supply input for biasing steering diodes; reduces capacitance and sets clamping threshold to VCC + VF. |
| 6 | I/O Line 4 | Fourth protected line (e.g., DVI TMDS−); fully symmetric with Pins 1/3/4 in layout and function. |
Key Features
| Feature | Design Value |
|---|---|
| 4-line integrated protection | Single TSOP-6 package replaces four discrete diodes and one TVS, reducing PCB area by >60% vs. discrete solution. |
| Low clamping voltage | 12.5 V at 1 A ensures downstream ICs (e.g., USB transceivers) remain within absolute maximum ratings during ESD. |
| Sub-5 pF I/O-to-GND capacitance | Preserves signal rise/fall times on 480 Mbps USB 2.0 channels; measured at 1 MHz, 0 V bias. |
| VCC-referenced steering | Pin 5 connection to VCC lowers diode capacitance and enables clamping to VCC + VF instead of ground-only paths. |
| IEC61000-4-4/4-5 compliance | Withstands 40 A EFT bursts and 12 A lightning surges-critical for industrial Ethernet and telecom interfaces. |
Applications
| USB 2.0 Port Protection | DVI Interface Protection |

Use Value: Withstands 12 A IEC61000-4-5 lightning surges while maintaining <5 pF capacitance-critical for maintaining T1's 1.544 Mbps timing accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NUP2201DT1G | 2-channel, 5.5 V VRWM, 15.5 V VC @ 1 A, 12 pF I/O-to-GND capacitance | Higher capacitance limits use to ≤12 Mbps interfaces; lacks 4-line integration | Select when only two lines require protection and board space permits larger capacitance tolerance. |
| TPD2E001DRYR | 2-channel, 5 V VRWM, 12 V VC @ 1 A, 3.5 pF I/O-to-GND, SOT-563 package | Only protects two lines; requires two devices for four-line coverage; smaller 1.6 mm × 1.6 mm footprint | Choose for ultra-compact layouts where dual-device placement is acceptable and 3.5 pF capacitance is preferred over integration. |
Compared with NUP2201DT1G and TPD2E001DRYR, the SRV05-4MR6T1G delivers true 4-line integration in TSOP-6, lower clamping (12.5 V vs. 15.5 V), and tighter capacitance control (3–5 pF vs. 12 pF or 3.5 pF), making it optimal for space-constrained, high-speed USB/DVI designs requiring single-package simplicity.

FAQ
What is the maximum clamping voltage of SRV05-4MR6T1G under IEC61000-4-2 ESD stress?
The SRV05-4MR6T1G exhibits a clamping voltage of 12.5 V at 1 A and 17.5 V at 5 A under 8×20 µs pulse conditions per IEC61000-4-2. Oscilloscope screenshots in the official datasheet confirm these values for both positive and negative 8 kV contact discharges, ensuring protected ICs remain within safe operating limits during real-world ESD events.
How does SRV05-4MR6T1G achieve low capacitance while maintaining high ESD robustness?
The SRV05-4MR6T1G achieves ≤5.0 pF I/O-to-GND capacitance through optimized silicon geometry and process tuning, while sustaining 300 W peak power via integrated TVS and steering diode architecture. This balance allows it to protect 480 Mbps USB 2.0 links without signal degradation-unlike discrete solutions where robustness typically increases capacitance.
Can SRV05-4MR6T1G be used for bidirectional signal lines like RS-485?
No-SRV05-4MR6T1G is a unidirectional TVS array designed for single-ended or differential data lines referenced to VCC or ground (e.g., USB, DVI). It lacks symmetrical breakdown for true bidirectional clamping. For RS-485, use bidirectional arrays such as NUP4201MR6T1G or SMAJ5.0A, which specify equal positive/negative clamping thresholds.
What is the recommended PCB layout practice for SRV05-4MR6T1G to minimize inductive effects during ESD events?
Minimize trace length from SRV05-4MR6T1G pins 1/3/4/6 to connectors and from pins 2 (VN) and 5 (VP) to low-inductance ground/power planes. Use solid ground pour beneath the device, avoid vias in protection paths, and place the SRV05-4MR6T1G within 5 mm of the protected connector to limit L·di/dt voltage overshoot during nanosecond-scale ESD transients.
Is SRV05-4MR6T1G compliant with lead-free soldering standards and RoHS requirements?
Yes-SRV05-4MR6T1G is explicitly marked "Pb-Free" in its ordering code and meets J-STD-020 moisture sensitivity level 1 (MSL1) requirements. Its TSOP-6 package supports reflow profiles up to 260°C peak temperature for 10 seconds, complying with IPC/JEDEC J-STD-020D and RoHS Directive 2011/65/EU.
