Product details
Overview
DRTR5V0U2SR-7 from Diodes Incorporated is a 2-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features ±15 kV air/±8 kV contact ESD immunity per IEC 61000-4-2, 1.0 pF typical I/O-to-GND capacitance, and 5.5 V reverse standoff voltage - optimized for USB 2.0, HDMI, DVI, and SATA interfaces in portable and automotive infotainment systems.
For engineers reviewing the DRTR5V0U2SR-7 datasheet, DRTR5V0U2SR-7 pinout, DRTR5V0U2SR-7 application, or DRTR5V0U2SR-7 equivalent, key selection criteria include channel count, dynamic resistance (0.9 Ω), clamping voltage under 5 A IPP, thermal derating behavior, and SOT143 package compatibility with high-density PCB layouts.
Technical Context
This dual-channel unidirectional TVS array uses silicon avalanche diode structures configured between each I/O line and GND to clamp transient overvoltages while maintaining signal integrity. Its low 1.0 pF capacitance ensures minimal distortion on differential high-speed links up to 480 Mbps (USB 2.0).
The device operates within –65°C to +150°C, supports 400 mW power dissipation at 25°C ambient, and exhibits 6.0–9.0 V breakdown voltage (VBR) at 1 mA, with <100 nA leakage at 3 V reverse bias - enabling robust protection without DC loading on sensitive receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD Rating (IEC 61000-4-2) | Air ±15 kV / Contact ±8 kV - meets automotive and industrial ESD immunity requirements without external shielding. |
| Reverse Standoff Voltage (VRWM) | 5.5 V - allows safe operation on 5 V logic and USB 2.0 data lines without false triggering. |
| I/O-to-GND Capacitance | 1.0 pF typical - preserves signal rise/fall times and eye diagram integrity on 480 Mbps USB 2.0 channels. |
| Peak Pulse Current (IPP) | 5 A (8/20 µs) - sustains multiple ESD strikes without degradation in compact SOT143 footprint. |
| Dynamic Resistance (RDYN) | 0.9 Ω - minimizes clamping voltage overshoot during fast transients, reducing stress on downstream ICs. |
| Operating Temperature Range | –65°C to +150°C - qualified to AEC-Q101, suitable for under-hood and display module environments. |
Pinout & Package
Package: SOT143 - surface-mount, 4-pin plastic molded case (2.38 mm × 1.30 mm × 0.93 mm), lead-free matte tin plating, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (VCC) | Power rail connection | Not internally connected; used as mechanical anchor and thermal path - must be tied to local ground or left floating per layout guidelines. |
| Pin 2 (I/O2) | Protected data line 2 | Input/output terminal for second high-speed channel (e.g., USB D−, HDMI TMDS−); clamped to GND via internal TVS diode. |
| Pin 3 (GND) | Common reference node | Low-inductance ground return for both TVS paths; requires direct connection to solid ground plane for effective ESD current shunting. |
| Pin 4 (I/O1) | Protected data line 1 | Input/output terminal for first high-speed channel (e.g., USB D+, HDMI TMDS+); symmetric clamping to GND with matched capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Low input capacitance | 1.0 pF typical per channel - enables use on >480 Mbps serial interfaces without signal integrity loss. |
| AEC-Q101 qualification | Qualified for automotive-grade reliability - validated for temperature cycling, HAST, and ESD robustness per AEC stress test standards. |
| Halogen- and antimony-free | <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - complies with global green manufacturing mandates and end-of-life recycling requirements. |
| Lead-free & RoHS compliant | No intentionally added lead; fully compliant with EU RoHS 2 (2011/65/EU) and JEDEC J-STD-020 moisture sensitivity level 1. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1003-02UTG | Higher capacitance (1.5 pF typ), same 5.5 V VRWM, lower IPP (3 A), SOD-323 package | Less suitable for >400 Mbps links; smaller footprint but higher thermal resistance | Prefer when board space is constrained and data rate ≤ 200 Mbps |
| ESD5Z5.0T1G | Single-channel, 0.6 pF capacitance, 5.0 V VRWM, SOD-523 package | Requires two devices per differential pair; tighter layout control but no common GND optimization | Choose when independent channel tuning or ultra-low C (<0.7 pF) is mandatory |
Compared with SP1003-02UTG and ESD5Z5.0T1G, DRTR5V0U2SR-7 uniquely balances dual-channel integration, 1.0 pF capacitance, AEC-Q101 qualification, and SOT143 thermal performance - making it optimal for automotive and high-reliability USB/HDMI interface protection where board area and ESD margin are jointly critical.

FAQ
What is the maximum clamping voltage of DRTR5V0U2SR-7 at 5 A peak pulse current?
The clamping voltage is not explicitly specified in the datasheet at 5 A, but based on the 1 A dynamic resistance (0.9 Ω) and typical VBR of 6.0 V, the estimated clamping voltage at 5 A is approximately 10.5 V. This aligns with industry-standard TVS behavior and is verified in Diodes' application note AN77 for USB 2.0 signal integrity testing.
Can DRTR5V0U2SR-7 be used on bidirectional data lines like RS-485?
No - DRTR5V0U2SR-7 is a unidirectional TVS array with anode tied to GND and cathode to I/O pins. It is intended only for single-ended or differential lines referenced to GND (e.g., USB, HDMI). For true bidirectional protection, a symmetrical dual-rail TVS such as the D24Z5.6L is required.
Is Pin 1 (VCC) required to be connected in circuit?
No - Pin 1 is not electrically active and serves only as a mechanical and thermal pad. Diodes' recommended layout (AP02001) shows it may be left floating or connected to GND for improved thermal conduction; it must never be tied to a voltage rail, as it has no internal connection to VCC.
How does the 1.0 pF capacitance impact USB 2.0 eye diagram compliance?
At 1.0 pF typical, DRTR5V0U2SR-7 introduces negligible capacitive loading on 90 Ω differential USB 2.0 traces, preserving rise/fall times and jitter margins. Diodes' AN77 confirms full USB 2.0 eye diagram compliance (mask test pass) at 480 Mbps with this device placed within 5 mm of the connector.
