Product details
Overview
VESD01A2-03GHG3-08 from Vishay Semiconductors is a dual-line unidirectional ESD-protection diode array in SOT-323 package, rated for 1 V reverse stand-off voltage, ±30 kV IEC 61000-4-2 contact/air discharge immunity, and 70 W peak pulse power (8/20 μs), deployed in USB 2.0 data line protection.
For engineers reviewing the VESD01A2-03GHG3-08 datasheet, VESD01A2-03GHG3-08 pinout, VESD01A2-03GHG3-08 application, or VESD01A2-03GHG3-08 equivalent, key selection criteria include clamping voltage at 11 A (≤6.4 V), dynamic resistance (0.13 Ω), capacitance (192 pF typ), and AEC-Q101 qualification status.
Technical Context
This device implements two independent unidirectional TVS diodes in a single SOT-323 package, with cathode-anode-cathode pin configuration enabling bidirectional signal line protection via common cathode architecture. Each channel provides low-clamping, low-capacitance transient suppression for high-speed interfaces.
It operates across –55 °C to +150 °C junction temperature range, supports lead-free reflow up to 260 °C peak, and meets MSL level 1 per J-STD-020 - eliminating bake requirements prior to assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Stand-off Voltage | 1 V - defines maximum continuous operating voltage before leakage exceeds 100 μA; matches low-voltage logic rails like 1.2 V I/O. |
| Reverse Clamping Voltage | 6.4 V max at 11 A (8/20 μs) - ensures protected ICs see sub-6.4 V transients during ESD events. |
| Capacitance | 192 pF typical at 0 V, 1 MHz - optimized for USB 2.0 (480 Mbps) without signal integrity degradation. |
| ESD Immunity | ±30 kV contact / ±30 kV air per IEC 61000-4-2 - exceeds Level 4 system-level ESD requirements. |
| Peak Pulse Power | 70 W (8/20 μs) - sustains single high-energy surges without failure, validated per IEC 61000-4-5. |
| Dynamic Resistance | 0.13 Ω typical - minimizes voltage overshoot during fast-rising ESD pulses (TLP, 100 ns). |
Pinout & Package
SOT-323 package: 3-pin surface-mount plastic case (2.2 × 1.35 × 0.95 mm), MSL level 1, Sn (e3) lead finish, compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Channel 1 | Connects to protected signal line 1 (e.g., USB D+); conducts during negative transients. |
| 2 | Anode of Channel 2 | Connects to protected signal line 2 (e.g., USB D−); independent conduction path for second line. |
| 3 | Common Cathode | Reference node tied to ground or low-impedance return; enables compact dual-channel layout. |
Key Features
| Feature | Design Value |
|---|---|
| Dual unidirectional protection | Two independent anode-to-cathode paths allow separate routing of high-speed differential pairs without cross-talk coupling. |
| AEC-Q101 qualified option | Available in H-grade variant (VESD01A2-03GHG3A08) for automotive infotainment and body electronics. |
| Low dynamic resistance | 0.13 Ω enables rapid clamping response (<1 ns effective turn-on), critical for sub-nanosecond ESD rise times. |
| Controlled capacitance profile | 192 pF typ at 0 V, decreasing with reverse bias - preserves signal edge rate in 480 Mbps USB 2.0 links. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2E001DRYR | Single-channel, 1.8 V VRWM, 12 pF capacitance, 5.5 V VC @ 4 A | Lower capacitance but only one channel; requires two devices for dual-line protection | Select when ultra-low capacitance (<15 pF) is mandatory and board space allows dual placement. |
| ESD5Z3.3T5G | Single-line unidirectional, 3.3 V VRWM, 120 pF capacitance, 12 V VC @ 4 A | Higher clamping voltage and stand-off voltage; not suitable for 1 V logic interfaces | Choose for 3.3 V I/O protection where lower cost and higher surge rating (120 W) outweigh capacitance trade-offs. |
Compared with TPD2E001DRYR and ESD5Z3.3T5G, VESD01A2-03GHG3-08 uniquely delivers dual-channel 1 V stand-off capability in one SOT-323 footprint, balancing low clamping (6.4 V), moderate capacitance (192 pF), and automotive-grade reliability - making it optimal for space-constrained, low-voltage differential interface protection.

FAQ
What is the maximum clamping voltage of the VESD01A2-03GHG3-08 under IEC 61000-4-5 surge conditions?
The VESD01A2-03GHG3-08 exhibits a maximum reverse clamping voltage of 6.4 V when subjected to an 11 A, 8/20 μs peak pulse current per IEC 61000-4-5. This value is measured between pins 1–3 or 2–3 and ensures downstream ICs remain within safe voltage limits during surge events. The VESD01A2-03GHG3-08 achieves this with a low dynamic resistance of 0.13 Ω, minimizing overshoot during fast transients.
Does the VESD01A2-03GHG3-08 support automotive qualification standards?
Yes, the VESD01A2-03GHG3-08 is offered in an AEC-Q101 qualified variant (marked as VESD01A2-03GHG3A08). While the base part number VESD01A2-03GHG3-08 itself is not automatically qualified, its H-grade version undergoes stress testing per AEC-Q101 including HTGB, AC/DC life test, and temperature cycling - validating suitability for automotive infotainment and body control modules.
How does the capacitance of VESD01A2-03GHG3-08 affect USB 2.0 signal integrity?
The VESD01A2-03GHG3-08 has a typical capacitance of 192 pF at 0 V and 1 MHz, which is carefully balanced to avoid excessive signal attenuation or jitter in USB 2.0 (480 Mbps) differential links. Its capacitance decreases with applied reverse bias, reducing loading during normal operation. The VESD01A2-03GHG3-08 maintains eye diagram compliance per USB-IF specifications when placed adjacent to connectors with proper layout practices.
Can VESD01A2-03GHG3-08 be used for bidirectional signal lines like RS-485?
No - the VESD01A2-03GHG3-08 is a unidirectional dual-diode array (anode-cathode-anode configuration), designed for single-polarity transient suppression relative to ground. For true bidirectional protection such as RS-485, a symmetric arrangement like a dual-bidirectional TVS (e.g., VESD05A2-03G) or external steering diodes would be required. The VESD01A2-03GHG3-08 is intended for unidirectional data lines referenced to ground, such as USB D+/D−.
What is the moisture sensitivity level (MSL) and reflow profile compatibility of VESD01A2-03GHG3-08?
The VESD01A2-03GHG3-08 is rated MSL level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/60 % RH without baking prior to reflow. It supports standard Pb-free reflow with a peak temperature of 260 °C, compatible with IPC/JEDEC J-STD-020 profiles. The SOT-323 package uses UL 94 V-0 flame-retardant molding compound, ensuring process robustness and safety compliance.
