Product details
Overview
DT1452-02SOQ from Diodes Incorporated is a dual-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It features 7V minimum breakdown voltage, 12A peak pulse current (8/20µs), 1.2pF typical channel input capacitance, ±16kV IEC61000-4-2 contact/air ESD rating, and AEC-Q101 qualification for automotive use in HDMI and USB 2.0 interfaces.
For engineers reviewing the DT1452-02SOQ datasheet, DT1452-02SOQ pinout, DT1452-02SOQ application, or DT1452-02SOQ equivalent, key selection criteria include clamping voltage at 5A/12A, dynamic resistance, leakage current at 5.5V, thermal derating above 25°C, and SOT23 footprint compatibility with high-speed signal integrity requirements.
Technical Context
This device implements a dual-channel unidirectional TVS structure with cathode-to-VSS configuration, enabling simultaneous protection of two independent I/O lines against transient overvoltages. Its low 1.2pF input capacitance minimizes signal distortion on differential pairs operating up to 480 Mbps (USB 2.0) and supports HDMI 1.4 compliance.
The 7.5V clamping voltage at 5A and 9.5V at 12A ensures robust suppression of EFT and lightning surges per IEC61000-4-4 (55A) and IEC61000-4-5 (12A), while maintaining sub-1μA reverse leakage at 5.5V working voltage - critical for preserving signal integrity in battery-powered automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 7 V min - triggers protection before downstream IC damage at 5.5V working voltage |
| Clamping Voltage (VC) | 7.5 V @ 5A - limits transient voltage seen by protected IC during ESD event |
| Peak Pulse Current (IPP) | 12 A @ 8/20µs - withstands automotive-level lightning surge per IEC61000-4-5 |
| Input Capacitance (CI/O) | 1.2 pF typ - preserves signal rise/fall time in USB 2.0 and HDMI applications |
| ESD Rating | ±16 kV contact/air - exceeds IEC61000-4-2 Level 4 for system-level ESD immunity |
| Reverse Leakage (IR) | 1.0 μA max @ 5.5V - avoids DC loading on high-impedance receiver inputs |
Pinout & Package
Package: SOT23 - surface-mount, 3-pin plastic case with matte tin-plated Alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020; UL 94V-0 rated molding compound; 0.009 g weight.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel TVS diode array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J5.0A-Q | Single-channel, 5.0V VRWM, higher 20pF capacitance, DO-214AC package | Requires two devices for dual-line protection; unsuitable for >100 Mbps signals due to capacitance | Select only when space permits discrete placement and speed <10 Mbps |
| TPD2E001DRYR | 2-channel, 1.0pF CI/O, 5.5V VRWM, 3.5V clamping at 1A - lower voltage rating, no AEC-Q101 | Not qualified for automotive underhood use; limited to consumer-grade infotainment displays | Prefer for cost-sensitive non-automotive USB/HDMI designs requiring ultra-low capacitance |
Compared with SMA6J5.0A-Q and TPD2E001DRYR, DT1452-02SOQ uniquely balances AEC-Q101 qualification, 1.2pF capacitance, and 7V breakdown in a single SOT23 package - making it the only option validated for automotive HDMI/USB 2.0 protection without design compromise.

FAQ
What is the maximum operating temperature for DT1452-02SOQ in continuous use?
The DT1452-02SOQ is rated for continuous operation from −55°C to +150°C ambient temperature. Its thermal resistance (RθJA = 417°C/W) and 300 mW power dissipation limit require PCB pad layout per Diodes' recommended SOT23 footprint to maintain junction temperature below 150°C under worst-case surge conditions.
Can DT1452-02SOQ protect bidirectional data lines like USB D+/D−?
Yes - though configured as unidirectional (anode-to-I/O, cathode-to-VSS), DT1452-02SOQ protects bidirectional signals by clamping positive transients to VSS and relying on the host IC's internal ESD diodes for negative excursions. This architecture is validated for USB 2.0 and HDMI per Diodes' application notes DS41853 and AN-4001.
Is the 1.2pF input capacitance measured at DC or AC bias?
The 1.2pF typical input capacitance is measured at VR = 2.5V DC bias, f = 1 MHz. The datasheet confirms capacitance variation is only ±0.03pF across 0–2.5V, ensuring stable impedance matching for high-speed differential signaling without retuning PCB trace lengths.
Does DT1452-02SOQ require external series resistors for optimal ESD performance?
No - the device is designed for direct placement adjacent to connectors without series impedance. Its 0.22Ω dynamic resistance and fast turn-on (sub-nanosecond) eliminate need for current-limiting resistors, which would degrade signal integrity in USB 2.0 and HDMI applications per Diodes' layout guidelines in DS41853.
