Product details
Overview
VGSOT04C-HG3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode dual-channel configuration, 4 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2 ESD immunity, and 540 W peak pulse power (8/20 μs). It protects high-speed data lines such as USB 2.0 and HDMI interfaces against electrostatic discharge.
For engineers reviewing the VGSOT04C-HG3-08 datasheet, VGSOT04C-HG3-08 pinout, VGSOT04C-HG3-08 application, or VGSOT04C-HG3-08 equivalent, key selection criteria include its 40 A peak pulse current rating, bidirectional asymmetrical (BiAs) clamping behavior, low 360–450 pF line capacitance at 0 V, AEC-Q101 qualification option, and compatibility with automated SMT assembly on 7" or 13" tape reels.
Technical Context
The VGSOT04C-HG3-08 implements a dual-diode common-anode topology enabling simultaneous protection of two signal lines to ground. Its BiAs-mode operation delivers asymmetric clamping: forward conduction limits negative transients near 0 V (VF ≤ 1.2 V), while reverse breakdown (VBR = 5–7 V) handles positive surges with VC ≤ 13.5 V at 40 A.
It supports both two-line unidirectional protection (pins 1 & 2 to protected lines, pin 3 to ground) and single-line bidirectional protection (pins 1 & 2 across line-to-ground, pin 3 unused), with VRWM = 4 V (dual-line) or 4.5 V (single-line) and junction temperature range of –55 °C to +150 °C.
Key Specifications

Use Value: AEC-Q101 qualification guarantees operation from –55 °C to +150 °C; 4 V VRWM matches typical 3.3 V logic rail systems. | Use Scenario: Adding secondary ESD protection on CAN FD transceiver side (CANH/CANL) where primary protection resides on connector side. IC Role / Device Role / Timing Role: Dual-channel clamp applied across CANH–GND and CANL–GND, exploiting BiAs-mode to avoid false triggering during common-mode noise. Use Value: Low 20 μA IR prevents bus loading; 5–7 V VBR avoids interference with 2.5–5 V CAN FD signal levels while clamping >10 V transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J4.5A | Single-channel, higher VRWM (4.5 V), higher VC (14.5 V @ 38.5 A), larger SMA package (5.3 mm × 4.3 mm) | Requires two devices for dual-line protection; less space-efficient than SOT-23 dual-channel solution | Select when discrete replacement of failed legacy TVS or when board area allows larger footprint |
| TPD2E001DRYR | Two-channel, 5.5 V VRWM, lower CD (15 pF typical), but only ±8 kV ESD rating and no AEC-Q101 option | Better for ultra-high-speed interfaces (e.g., USB 3.0), but insufficient for automotive or industrial ESD stress environments | Select for cost-sensitive consumer electronics where ±30 kV immunity is not required |
Compared with SMA6J4.5A and TPD2E001DRYR, VGSOT04C-HG3-08 uniquely combines dual-line SOT-23 integration, ±30 kV ESD immunity, AEC-Q101 qualification, and balanced capacitance–clamping trade-off-making it optimal for space-constrained automotive and industrial data line protection.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT04C-HG3-08?
The VGSOT04C-HG3-08 has a maximum reverse working voltage (VRWM) of 4 V when used in two-line unidirectional mode (pins 1 and 2 to signal lines, pin 3 to ground). This value ensures reliable operation below the diode's breakdown threshold while maintaining low leakage (≤20 μA) in normal signal conditions. The VRWM is confirmed in the "ELECTRICAL CHARACTERISTICS VGSOT04C" section of Vishay document 86325.
How does the VGSOT04C-HG3-08 support bidirectional ESD protection?
The VGSOT04C-HG3-08 supports bidirectional protection via BiSy-mode: pins 1 and 2 are connected across a single signal line and ground (pin 3 left open), enabling symmetrical clamping of both positive and negative transients. In this configuration, VRWM increases to 4.5 V and clamping occurs through one diode in forward bias and the other in reverse, delivering matched VC performance. This mode is explicitly detailed in the "BiSy-MODE" section of the datasheet.
Is the VGSOT04C-HG3-08 qualified to AEC-Q101?
Yes, the VGSOT04C-HG3-08 is AEC-Q101 qualified. The "HG" in the part number denotes the AEC-Q101 qualified version, and the "G3" suffix indicates green (lead-free) packaging. This qualification is confirmed in the Ordering Information table and Package Data section of Vishay document 86325, which lists VGSOT04C-HG3-08 as an AEC-Q101 qualified option with MSL level 1 and peak reflow temperature of 260 °C.
What is the peak pulse power rating of the VGSOT04C-HG3-08?
The VGSOT04C-HG3-08 delivers 540 W peak pulse power (PPP) under 8/20 μs waveform per IEC 61000-4-5, measured at 40 A peak pulse current (IPPM). This rating applies to each channel independently in dual-line mode. The 10/1000 μs rating is 44 W. These values are specified in the "ABSOLUTE MAXIMUM RATINGS VGSOT04C" table on page 2 of Vishay document 86325.
Can the two channels of the VGSOT04C-HG3-08 be paralleled for higher surge capability?
Yes, the two protection diodes inside the VGSOT04C-HG3-08 can be paralleled to double peak pulse current handling to 80 A and double peak pulse power to 1080 W (8/20 μs), while halving effective series impedance and reducing clamping voltage. This technique is explicitly recommended in the "BiAs-MODE" application note on page 5 of Vishay document 86325, noting trade-offs including doubled capacitance and leakage current.
