Product details
Overview
D1213A-02WLQ from Diodes Incorporated is a dual-channel, low-capacitance TVS diode array designed for ESD protection of high-speed data lines. It delivers ±25 kV contact / ±30 kV air IEC 61000-4-2 ESD immunity, 0.85 pF typical channel capacitance, 5.5 V reverse working voltage, and 10.0 V clamping voltage at 1 A, making it suitable for USB 2.0, HDMI, and SATA interfaces in automotive and industrial systems.
For engineers reviewing the D1213A-02WLQ datasheet, D1213A-02WLQ pinout, D1213A-02WLQ application, or D1213A-02WLQ equivalent, key selection criteria include channel capacitance ≤1.2 pF, clamping voltage under 10.5 V at 1 A, AEC-Q101 qualification, SOT323 package compatibility, and dual-channel GND-referenced topology for differential signal protection.
Technical Context
This device implements two independent bidirectional TVS diodes in a single SOT323 package, each connected between an I/O line and ground. Its low dynamic resistance (0.9 Ω) and fast response time (<1 ns) enable effective transient suppression without distorting high-frequency signals up to 480 Mbps.
The junction capacitance remains stable below 1.2 pF across 0–1.65 V reverse bias at 1 MHz, ensuring minimal signal integrity impact on USB 2.0 and HDMI 1.4a channels. Thermal design leverages a 625 °C/W junction-to-ambient resistance on standard FR-4 with 2 oz copper pads.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel low-capacitance TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SP1006-02UTG | 0.6 pF typical capacitance, 5.0 V VRWM, 9.5 V clamping at 1 A | Better suited for 1.8 V/2.5 V interfaces; lower clamping but narrower voltage margin | Select when protecting low-voltage SerDes lanes where <0.7 pF is mandatory and 5.0 V max operating voltage applies |
| TPD2E001DRYR | 1.0 pF typical capacitance, 5.5 V VRWM, 12.5 V clamping at 1 A, integrated ESD protection diode + RC filter | Includes series resistor for additional filtering; higher clamping reduces margin for sensitive receivers | Choose when board space allows RC-based filtering and system-level testing permits 12.5 V transient overshoot |
Compared with SP1006-02UTG and TPD2E001DRYR, D1213A-02WLQ offers optimal balance of 5.5 V VRWM margin, 10.0 V clamping, and 0.85 pF capacitance for 3.3 V high-speed interfaces, while maintaining AEC-Q101 qualification and SOT323 footprint compatibility.

FAQ
What is the maximum operating temperature range for D1213A-02WLQ?
The D1213A-02WLQ is rated for operation from –65 °C to +150 °C, fully compliant with AEC-Q101 stress testing requirements. This range covers under-hood automotive environments and industrial control enclosures where ambient temperatures exceed 125 °C. Derating begins at +25 °C per the published power dissipation curve.
Can D1213A-02WLQ protect both differential and single-ended signals?
Yes - its dual-channel bidirectional architecture protects two independent I/O lines referenced to common GND, supporting both single-ended (e.g., USB D+, D–) and differential pair (e.g., HDMI TMDS+) configurations. Each channel operates symmetrically, enabling use on either side of a differential pair without polarity constraints.
Is the SOT323 package compatible with standard reflow profiles?
Yes - the SOT323 package is qualified for lead-free reflow per JEDEC J-STD-020, with moisture sensitivity level 1 (unlimited floor life). Recommended peak temperature is 260 °C for ≤60 seconds; solder wettability is verified per MIL-STD-202, Method 208 using matte tin plating over alloy 42 leadframe.
How does D1213A-02WLQ compare to monolithic multi-channel TVS arrays in terms of layout flexibility?
D1213A-02WLQ's 3-pin SOT323 layout enables compact placement directly at I/O connectors with minimal trace length, reducing parasitic inductance. Unlike 6-pin or 8-pin arrays, it avoids routing complexity between adjacent channels, preserving impedance matching on high-speed lines such as USB 2.0 and HDMI.
