Product details
Overview
VESD05A2-03GHG3-08 from Vishay Semiconductors is a dual-line unidirectional ESD-protection diode array in SOT-323 package, designed for I/O line protection in 5 V systems. It delivers 30 kV IEC 61000-4-2 contact/air discharge immunity, 100 W peak pulse power (8/20 μs), and 53–81 pF capacitance at 0 V bias, enabling robust USB 2.0 and HDMI interface protection.
For engineers reviewing the VESD05A2-03GHG3-08 datasheet, VESD05A2-03GHG3-08 pinout, VESD05A2-03GHG3-08 application, or VESD05A2-03GHG3-08 equivalent, this page provides verified electrical parameters, SOT-323 terminal mapping, AEC-Q101 qualification status, clamping performance under 8.7 A transient current, and real-world use cases in automotive infotainment and industrial HMI interfaces.
Technical Context
This device implements two independent unidirectional TVS diodes in a single SOT-323 package, with common cathode configuration (pins 1 & 2 anodes, pin 3 cathode). Its 5 V reverse standoff voltage (VRWM) and 6.85–7.65 V breakdown (VBR at 1 mA) ensure compatibility with standard 5 V logic rails while maintaining low leakage (<0.1 μA at VR = 5 V).
The 10.3–11.5 V reverse clamping voltage at 8.7 A (IPPM) and 0.2 Ω dynamic resistance (rdyn) enable fast, low-voltage transient suppression. It meets AEC-Q101 stress requirements and supports reflow soldering up to 260 °C (MSL level 1).

IC Role / Device Role / Timing Role: Dual-line protector with common cathode tied to clean analog ground, minimizing crosstalk between differential pairs. Use Value: Achieves ±30 kV contact discharge immunity without degrading signal rise/fall times due to controlled 0.2 Ω rdyn and sub-81 pF CD. |
Use Scenario: Protecting RS-485/RS-232 signal lines in factory automation HMIs where operators frequently touch metal enclosures. IC Role / Device Role / Timing Role: Unidirectional clamp on TX/RX lines referenced to local 5 V supply, absorbing ESD pulses before reaching transceiver IC.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A | Single-channel, DO-214AC package (larger), 5.0 V VRWM, 100 W PPP, 13.4 V VC @ 9.9 A | Requires two devices for dual-line protection; higher capacitance (~350 pF) limits high-speed use | Select when board space allows larger packages and cost is prioritized over layout density |
| TPD2E001DRSR | Two-channel unidirectional, SOT-563, 5 V VRWM, 100 W PPP, 12 V VC @ 8 A, 15 pF typical CD | Lower capacitance enables USB 3.0 compatibility; not AEC-Q101 qualified | Prefer for consumer-grade high-speed interfaces where ultra-low capacitance outweighs automotive qualification needs |
Compared with SMAJ5.0A and TPD2E001DRSR, VESD05A2-03GHG3-08 uniquely balances compact SOT-323 size, AEC-Q101 readiness, 30 kV ESD rating, and 53–81 pF capacitance-making it optimal for space-constrained automotive and industrial 5 V data interfaces requiring proven reliability.

FAQ
What is the exact pin configuration of VESD05A2-03GHG3-08?
VESD05A2-03GHG3-08 uses a SOT-323 package with three terminals: Pin 1 is the anode of Channel 1, Pin 2 is the anode of Channel 2, and Pin 3 is the common cathode. This configuration supports unidirectional protection of two independent 5 V signal lines referenced to a shared ground or supply rail.
Does VESD05A2-03GHG3-08 meet AEC-Q101 qualification?
VESD05A2-03GHG3-08 is part of the VESDxxA2-03G series, for which AEC-Q101 qualification is explicitly offered (denoted by "H" in ordering code). The "H" in VESD05A2-03GHG3-08 confirms this unit is AEC-Q101 qualified, validated for automotive applications including temperature cycling, mechanical shock, and ESD stress testing.
What is the maximum clamping voltage of VESD05A2-03GHG3-08 under ESD stress?
The maximum reverse clamping voltage (VC) of VESD05A2-03GHG3-08 is 11.5 V when subjected to its rated peak pulse current of 8.7 A (8/20 μs waveform per IEC 61000-4-5). This value ensures downstream 5 V logic components remain within safe operating voltage margins during transient events.
Can VESD05A2-03GHG3-08 be used for bidirectional signal lines like USB D+ and D−?
Yes - VESD05A2-03GHG3-08 is unidirectional but configured with separate anodes (Pins 1 and 2) and a common cathode (Pin 3), allowing it to protect bidirectional data lines such as USB 2.0 D+ and D− when the cathode is tied to ground. Its 5 V VRWM aligns with standard USB voltage levels and ensures low leakage during normal operation.
What is the moisture sensitivity level (MSL) and reflow profile for VESD05A2-03GHG3-08?
VESD05A2-03GHG3-08 has Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it is not moisture-sensitive and can be stored indefinitely at ambient conditions without baking. Its SOT-323 package supports standard lead-free reflow with peak temperature up to 260 °C, compatible with IPC/JEDEC J-STD-020-compliant thermal profiles.
