Product details
Overview
TESD24VS2BT RFG from Taiwan Semiconductor is a bidirectional ESD protection array in SOT-23 package, rated for 24V working voltage, 200W peak pulse power (8/20μs), 3A peak impulse current, and ±30kV IEC 61000-4-2 contact/air discharge immunity-designed for high-speed data lines including USB 2.0 and HDMI interfaces.
For engineers reviewing the TESD24VS2BT RFG datasheet, TESD24VS2BT RFG pinout, TESD24VS2BT RFG application, or TESD24VS2BT RFG equivalent, key selection criteria include clamping voltage at 3A (70V), junction capacitance (11pF @ 1MHz), reverse standoff voltage (24V), operating temperature range (–55°C to +150°C), and RoHS/halogen-free compliance for portable and PoE-powered systems.
Technical Context
The TESD24VS2BT RFG integrates two back-to-back TVS diodes in a single SOT-23-3 package, enabling symmetrical bidirectional transient suppression on differential or single-ended signal lines. Its low 11pF junction capacitance and 70V clamping voltage at 3A support signal integrity in 480Mbps USB 2.0 and HDMI 1.4 channels without distortion.
It meets IEC 61000-4-2 Level 4 (±30kV air/contact) and complies with JESD201 Class 1A whisker resistance and J-STD-020 Moisture Sensitivity Level 1-enabling reflow-compatible assembly in high-reliability consumer and industrial PCBs without baking.
Key Specifications

|---|---|
| PPPM | 200 W - peak power handling under 8/20μs surge, sufficient for IEC 61000-4-5 line surges in PoE PD front-ends |
| VWM | 24 V - maximum continuous DC operating voltage, matching 24V system rails and battery management inputs |
| VC @ IPP = 3 A | 70 V - clamping voltage during full-rated surge, limiting downstream IC stress below 70V |
| CJ @ 1 MHz | 11 pF - low capacitance preserves signal rise time & eye diagram integrity on USB 2.0/HDMI lines |
| ESD Rating | ±30 kV (contact/air) - exceeds IEC 61000-4-2 Level 4, eliminating need for secondary ESD stages |
| Operating Temp | –55°C to +150°C - supports automotive cabin, industrial control, and outdoor PoE equipment deployment |

Applications
| USB 2.0 Interface Protection | HDMI Signal Line Protection |
|---|---|
Use Scenario: ESD protection on D+ and D− lines of USB 2.0 host/device ports exposed to user handling in laptops and peripherals. IC Role / Device Role / Timing Role: Bidirectional TVS array clamping transients before they reach the USB transceiver PHY. Use Value: 11pF capacitance avoids signal degradation at 480 Mbps; ±30kV rating ensures pass-fail compliance in IEC 61000-4-2 pre-scan testing. | Use Scenario: Transient suppression on TMDS clock/data channels of HDMI 1.4 sources and sinks in monitors and set-top boxes. IC Role / Device Role / Timing Role: Low-capacitance TVS placed adjacent to HDMI connector to shunt ESD before signal integrity loss. Use Value: 70V clamping at 3A prevents HDMI receiver latch-up; SOT-23 placement minimizes stub length and impedance discontinuity. |
| Touch Panel Data Lines | PoE Powered Device (PD) Interface |
Use Scenario: ESD hardening of I²C or SPI bus lines connecting capacitive touch controller to overlay sensors in smartphones and tablets. IC Role / Device Role / Timing Role: Dual-channel TVS protecting bidirectional serial buses against finger-contact discharges. Use Value: Symmetric clamping maintains logic-level compatibility; 24V VWM accommodates 3.3V/5V I/O rails with headroom for overshoot. | Use Scenario: Surge protection on 24V DC input and data pair (e.g., MDI) of IEEE 802.3af/at PoE PDs such as IP cameras and VoIP phones. IC Role / Device Role / Timing Role: Front-end TVS absorbing lightning-induced surges and hot-swap transients on power/data lines. Use Value: 200W PPPM handles 8/20μs surges per IEC 61000-4-5; –55°C to +150°C rating supports outdoor enclosure operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T (Vishay) | Unidirectional, higher VC (80V @ 3A), larger SMA package (4.5×2.7 mm), 22pF CJ | Requires separate devices per line; unsuitable for differential signaling without redesign | Select when unidirectional clamping suffices and board space allows SMA footprint |
| ESD9X3.3S5 (ON Semiconductor) | Lower VWM (3.3V), lower PPPM (120W), same SOT-23, 15pF CJ | Only suitable for 3.3V logic; inadequate for 24V PoE or HDMI supply-rail coupling | Choose only for low-voltage digital I/O; not a functional substitute for 24V-system protection |
Compared with SMAJ24A-E3/57T and ESD9X3.3S5, the TESD24VS2BT RFG uniquely combines bidirectional 24V standoff, 70V clamping at 3A, 11pF capacitance, and SOT-23 size-making it the only drop-in solution for compact, high-speed, 24V-tolerant ESD protection without layout or bill-of-material changes.

FAQ
What is the clamping voltage of TESD24VS2BT RFG at 3A peak impulse current?
The TESD24VS2BT RFG has a maximum clamping voltage (VC) of 70 V when subjected to a 3 A peak impulse current with an 8/20 μs waveform. This value is specified in the Electrical Specifications table under "Clamping voltage(2)" and ensures downstream ICs remain within safe voltage limits during ESD events. The 70 V clamping level is critical for protecting 24 V-rated interfaces like PoE PD inputs and HDMI TMDS lines without overvoltage damage.
Is TESD24VS2BT RFG suitable for USB 2.0 differential pair protection?
Yes, TESD24VS2BT RFG is explicitly designed for USB 2.0 differential pair protection. Its bidirectional SOT-23 configuration allows direct placement across D+ and D− lines with Pin 1 and Pin 3 connected to the signal lines and Pin 2 grounded. With only 11 pF junction capacitance and ±30 kV ESD immunity, the TESD24VS2BT RFG preserves signal integrity at 480 Mbps while meeting IEC 61000-4-2 Level 4 compliance without additional filtering components.
Does TESD24VS2BT RFG meet RoHS and halogen-free requirements?
Yes, TESD24VS2BT RFG is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses matte tin-plated leads, UL 94 V-0 molding compound, and passes JESD201 Class 1A whisker testing. These qualifications are confirmed in the Mechanical Data and Features sections of the official Taiwan Semiconductor datasheet (Version B2101), making TESD24VS2BT RFG suitable for export to EU, Japan, and other regulated markets with strict environmental compliance mandates.
What is the marking code for TESD24VS2BT RFG on the physical device?
The marking code printed on the top surface of the TESD24VS2BT RFG is "W3", as documented in the Mechanical Data section. This three-character code identifies the device variant and is visible under 20x magnification on the SOT-23 package. The "W3" marking aligns with Taiwan Semiconductor's internal traceability system and matches the ordering code TESD24VS2BT RFG used for reel-based procurement (3K per 7″ reel).
Can TESD24VS2BT RFG be used in automotive cabin applications?
Yes, TESD24VS2BT RFG supports automotive cabin applications due to its extended junction temperature range of –55°C to +150°C and qualification to JESD201 Class 1A whisker resistance. While not AEC-Q200 qualified, its thermal and mechanical robustness-combined with ±30 kV ESD immunity and 200 W surge capability-makes it suitable for non-safety-critical cabin modules such as infotainment USB ports, HDMI displays, and touch panel interfaces where ambient temperatures remain within specification limits.
