Product details
Overview
TESDA24VB30P2CX from Taiwan Semiconductor is a bidirectional ESD protection diode in SOT-23 package, rated for ±30 kV IEC61000-4-2 contact/air discharge, 5 A IEC61000-4-5 surge current, and 24 V reverse working voltage. It protects two automotive IVN bus lines-such as CAN bus-from electrostatic discharge and lightning-induced transients.
For engineers reviewing the TESDA24VB30P2CX datasheet, TESDA24VB30P2CX pinout, TESDA24VB30P2CX application, or TESDA24VB30P2CX equivalent, key selection factors include clamping voltage at 5 A (≤42 V), junction capacitance (24.5–30 pF), dynamic resistance (0.38 Ω), AEC-Q101 qualification, and bidirectional dual-line protection capability.
Technical Context
The TESDA24VB30P2CX implements a symmetric bidirectional TVS structure optimized for low-capacitance, low-clamping-voltage transient suppression on 24 V automotive data/power lines. Its 0.38 Ω dynamic resistance and 33.7–38.3 V TLP clamping range (4–16 A) enable fast response to sub-100 ns ESD events while limiting voltage overshoot.
Designed specifically for in-vehicle network interfaces, it meets IEC61000-4-2 (±30 kV), IEC61000-4-4 (4 kV EFT), and IEC61000-4-5 (5 A, 8/20 µs) standards. The device operates across –55 °C to +175 °C junction temperature and is qualified to AEC-Q101 for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 24 V - Maximum continuous DC or RMS voltage applied without triggering conduction. |
| Clamping Voltage (IPP = 5 A) | ≤42 V - Peak voltage seen by protected circuit during 8/20 µs surge, critical for IC-level overvoltage margin. |
| ESD Rating (IEC61000-4-2) | ±30 kV contact & air - Confirmed immunity level for human-body-model ESD events in automotive assembly/test environments. |
| Junction Capacitance | 24.5–30 pF @ 1 MHz, 0 V - Low enough to avoid signal integrity degradation on CAN and other low-speed buses. |
| Dynamic Resistance | 0.38 Ω - Enables tight clamping control and efficient energy dissipation during fast transients. |
| Peak Pulse Power | 210 W @ 8/20 µs - Sustains high-energy surges without thermal failure under defined pulse conditions. |
Pinout & Package
SOT-23 plastic surface-mount package (JEDEC TO-236AB), 3-pin, moisture sensitivity level 1 per J-STD-020. Dimensions: 2.90 × 1.30 × 1.00 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Channel 1 | Connects to first protected line (e.g., CAN_H); forms one side of bidirectional clamping path. |
| Pin 2 | Cathode (Common Ground Reference) | Shared ground return for both channels; must be tied directly to low-inductance chassis/system ground. |
| Pin 3 | Anode of Channel 2 | Connects to second protected line (e.g., CAN_L); completes dual-line bidirectional protection topology. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood and cabin environments with full temperature cycling, humidity, and mechanical stress testing. |
| Bidirectional dual-channel protection | Single SOT-23 device protects two independent lines (e.g., CAN_H/CAN_L) without polarity constraints or external biasing. |
| Low dynamic resistance (0.38 Ω) | Minimizes voltage overshoot during fast transients, improving margin for downstream 3.3 V or 5 V interface ICs. |
| 24.5–30 pF junction capacitance | Preserves signal rise/fall times on 1 Mbps CAN and similar low-speed buses without measurable distortion. |
Applications
| Automotive CAN Bus Protection | General Purpose I/O Protection |
|---|---|
Use Scenario: Protecting CAN_H and CAN_L lines in body control modules, infotainment gateways, or ADAS ECUs exposed to ESD during service or assembly. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed at connector entry point to shunt ESD/surge energy to ground before reaching CAN transceiver. Use Value: Maintains CAN bus integrity up to ±30 kV ESD and 5 A lightning surges while adding <30 pF loading to preserve 1 Mbps timing margins. | Use Scenario: Safeguarding microcontroller GPIOs, sensor inputs, or power rails in portable instrumentation subject to handling ESD.

IC Role / Device Role / Timing Role: Low-capacitance bidirectional protector placed inline between connector and SoC interface, minimizing trace inductance impact. Use Value: Achieves ±30 kV ESD immunity without degrading signal edge rates due to sub-30 pF capacitance and sub-1 Ω dynamic impedance. | Use Scenario: Surge protection for 12–24 V supply lines feeding LIN, SENT, or FlexRay nodes in engine bay or chassis modules. IC Role / Device Role / Timing Role: Clamping diode configured across VCC–GND to suppress load-dump and ISO 7637-2 pulses on low-power IVN subsystems. Use Value: Withstands 210 W peak pulse power and operates from –55 °C to +175 °C, supporting under-hood thermal requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF24CA (ON Semiconductor) | Unidirectional dual-channel; higher clamping voltage (48 V @ 5 A); 35 pF capacitance. | Requires separate ground paths per channel; less suitable for differential bus protection like CAN. | Prefer TESDA24VB30P2CX when bidirectional symmetry, lower clamping, or tighter capacitance control is required. |
| TPD2E001DRYR (Texas Instruments) | Two-channel unidirectional; 12 V working voltage; 10 pF capacitance; no AEC-Q101 rating. | Targeted at consumer port protection; not qualified for automotive temperature or reliability stress. | Select TESDA24VB30P2CX for automotive IVN designs requiring AEC-Q101, 24 V operation, and ±30 kV ESD robustness. |
Compared with SMF24CA and TPD2E001DRYR, the TESDA24VB30P2CX uniquely delivers bidirectional 24 V protection with AEC-Q101 qualification, 42 V clamping at 5 A, and 24.5–30 pF capacitance-making it optimal for space-constrained, high-reliability CAN and IVN bus protection where polarity independence and automotive compliance are mandatory.

Does the TESDA24VB30P2CX meet automotive qualification standards?
Yes, the TESDA24VB30P2CX is AEC-Q101 qualified, confirming its reliability for automotive applications including temperature cycling, humidity testing, and mechanical shock. It operates across –55 °C to +175 °C junction temperature and supports under-hood and cabin deployment scenarios.
How many lines does the TESDA24VB30P2CX protect, and what is its configuration?
The TESDA24VB30P2CX protects two independent lines in a bidirectional configuration using a common-cathode SOT-23 package. Pin 1 and Pin 3 serve as anodes for each channel, while Pin 2 is the shared cathode tied to system ground-enabling symmetrical clamping for differential buses like CAN.
What is the clamping voltage of the TESDA24VB30P2CX at 5 A surge current?
The clamping voltage of the TESDA24VB30P2CX is guaranteed ≤42 V at 5 A (8/20 µs waveform), per IEC61000-4-5. This value ensures downstream components-such as CAN transceivers-are exposed to minimal overvoltage during high-energy transients.
