Product details
Overview
GSOT05C-HE3-08 from Vishay Semiconductors is a two-line bidirectional ESD protection diode in SOT-23 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 5 V maximum reverse working voltage (VRWM), and 30 A peak pulse current (IPPM) per line to ground. It delivers 480 W peak pulse power (pin 1–3 or 2–3) and supports automotive-grade AEC-Q101 qualification in its qualified variants.
For engineers reviewing the GSOT05C-HE3-08 datasheet, GSOT05C-HE3-08 pinout, GSOT05C-HE3-08 application, or GSOT05C-HE3-08 equivalent, this device is selected for high-reliability USB 2.0, HDMI, and automotive infotainment data-line protection where low clamping voltage (12 V at 30 A), 260 pF capacitance at 0 V, and BiAs-mode asymmetrical clamping are critical design requirements.
Technical Context
The GSOT05C-HE3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: pin 3 is grounded, pins 1 and 2 protect two independent signal lines, with distinct forward (VF ≈ 1.0–1.2 V) and reverse (VBR = 6.0–8.0 V, VC = 12–16 V at 30 A) clamping behavior. Its dual-diode architecture enables parallel operation for doubled surge capability.
It also supports BiSy-MODE (Bidirectional Symmetrical) as a single-line protector when pin 3 is left unconnected and pins 1–2 form the protected path, delivering VRWM = 5.5 V, VBR = 6.5–8.7 V, and 130–175 pF capacitance - enabling flexible layout reuse across differential and single-ended interfaces.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT05C | Successor series with identical SOT-23 footprint, same VRWM (5 V), but improved 100 ps response time and lower 11 V clamping at 30 A. | Drop-in replacement for new designs; not recommended for legacy boards requiring exact parametric match to GSOT05C-HE3-08. | Select VGSOT05C for next-generation designs prioritizing tighter clamping and faster response; verify layout compatibility with revised thermal pad recommendations. |
| TPD2E001DRYR | TI dual-channel ESD protector in SOT-5X3 (1.6 × 1.6 mm); 5.5 V VRWM, 12 pF @ 0 V, 12 V VC at 4 A - lower capacitance but lower surge rating. | Better suited for high-speed USB 3.0 or MIPI where ultra-low capacitance is mandatory; insufficient for 30 A surge environments. | Choose TPD2E001DRYR only when signal bandwidth exceeds 1 GHz and surge exposure is limited to IEC 61000-4-2 only - not for IEC 61000-4-5 applications. |
Compared with VGSOT05C and TPD2E001DRYR, the GSOT05C-HE3-08 offers superior 30 A surge handling and proven AEC-Q101 qualification for automotive use, while trading off higher capacitance than ultra-high-speed alternatives - making it optimal for cost-sensitive, robust 480 Mbps data-line protection.

FAQ
What is the maximum reverse working voltage (VRWM) of the GSOT05C-HE3-08 in BiAs-MODE configuration?
The GSOT05C-HE3-08 has a maximum reverse working voltage (VRWM) of 5 V when used in BiAs-MODE (pins 1 and 2 to signal lines, pin 3 to ground). This rating ensures reliable operation with 3.3 V and 5 V logic systems while maintaining reverse leakage below 10 μA at full VRWM - critical for preserving signal integrity on always-on data lines.
Can the GSOT05C-HE3-08 be used in BiSy-MODE for single-line protection?
Yes, the GSOT05C-HE3-08 supports BiSy-MODE by leaving pin 3 unconnected and using pins 1 and 2 as a symmetrical clamp across one signal line and ground. In this mode, VRWM increases to 5.5 V, VBR ranges from 6.5 V to 8.7 V, and capacitance drops to 130–175 pF - enabling reuse in single-ended applications like RS-485 or analog sensor inputs without redesign.
What is the clamping voltage of the GSOT05C-HE3-08 at its maximum rated surge current?
At 30 A peak pulse current (IPPM) per line-to-ground path (IEC 61000-4-5, 8/20 μs waveform), the GSOT05C-HE3-08 clamps to a maximum of 16 V (reverse direction) and 4.5 V (forward direction). These values ensure downstream 3.3 V or 5 V ICs remain within absolute maximum ratings during severe transient events.
Is the GSOT05C-HE3-08 qualified to AEC-Q101 standards?
The GSOT05C-HE3-08 itself is part of the GSOT05C family, which includes AEC-Q101-qualified variants (e.g., GSOT05C-G3-08). While GSOT05C-HE3-08 carries RoHS-compliant e3 Sn plating and shares the same die and SOT-23 construction, formal AEC-Q101 certification applies only to explicitly marked qualified versions - confirm qualification status via Vishay's official documentation before automotive deployment.
How does parallel connection of two GSOT05C-HE3-08 devices affect performance?
Connecting two GSOT05C-HE3-08 devices in parallel doubles the peak pulse current rating to 60 A and peak pulse power to 960 W, halves effective series impedance (reducing clamping voltage), but doubles total capacitance (to ~520 pF) and reverse leakage (to ~20 μA). This configuration is validated in Vishay's application notes for high-stress industrial surge environments.
