Product details
Overview
VGSOT36C-HG3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring 36 V reverse stand-off voltage (VRWM), ±30 kV IEC 61000-4-2/ISO 10605 ESD immunity, and 400 W peak pulse power (8/20 μs). It operates from −55 °C to +150 °C and is AEC-Q101 qualified for automotive infotainment data lines.
For engineers reviewing the VGSOT36C-HG3-08 datasheet, VGSOT36C-HG3-08 pinout, VGSOT36C-HG3-08 application, or VGSOT36C-HG3-08 equivalent, this page delivers verified electrical specs, BiAs/BiSy dual-mode configuration guidance, clamping behavior under transient stress, and real-world use cases in high-reliability serial interfaces.
Technical Context
The VGSOT36C-HG3-08 implements a dual-channel common-anode topology enabling two-line unidirectional protection (BiAs mode) with asymmetric clamping: reverse breakdown at 39–47 V and forward clamping near 1.4 V at 5.6 A. Pin 3 serves as shared anode ground reference, while pins 1 and 2 connect to protected signal lines.
In BiSy mode (pin 3 floating), it functions as a single-line bidirectional protector with 36.5 V VRWM and symmetrical clamping-reverse breakdown at 39.5–47.7 V and forward conduction at ~1.4 V-enabling flexible deployment across UART, CAN FD, and USB 2.0 data lanes where polarity-agnostic surge suppression is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 36 V - Maximum continuous reverse working voltage before leakage exceeds 1 μA; sets upper limit for safe operation on 24 V automotive data buses. |
| VBR (min/typ/max) | 39 / 43 / 47 V - Reverse breakdown threshold at 1 mA; defines onset of clamping during positive transients. |
| VC @ IPPM = 5.6 A | 52–71 V - Clamped voltage during worst-case 8/20 μs surge; determines maximum stress imposed on downstream ICs. |
| Capacitance @ 0 V | 45–65 pF - Signal-line loading at DC bias; low enough for <100 Mbps USB 2.0 or CAN FD without distortion. |
| ESD immunity | ±30 kV contact/air discharge - Meets IEC 61000-4-2 and ISO 10605 Level 4; protects against human-body and system-level ESD events. |
| PPPM (8/20 μs) | 400 W - Peak pulse power handling capacity; supports robust protection against lightning-induced surges per IEC 61000-4-5. |
| TJ max. | +150 °C - Junction temperature rating; enables placement near hot components in engine control units or ADAS modules. |
Pinout & Package
SOT-23 package (3-pin, JEDEC TO-236AB), 9.2 mg weight, UL 94 V-0 molding compound, MSL level 1, lead (Pb)-free e3 Sn plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 cathode | Connects to first protected signal line (e.g., CAN_H); conducts ESD current to ground when voltage exceeds VBR. |
| Pin 2 | Line 2 cathode | Connects to second protected signal line (e.g., CAN_L); shares common anode (pin 3) for coordinated clamping. |
| Pin 3 | Common anode | Ground reference terminal; must be connected to system ground in BiAs mode; left floating in BiSy mode. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-line unidirectional protection (BiAs) | Enables simultaneous protection of differential pairs like CAN or RS-485 with asymmetric clamping-low VF (~1.4 V) for negative transients, controlled VC (<71 V) for positive surges. |
| Single-line bidirectional protection (BiSy) | Supports polarity-agnostic protection of UART or I²C by floating pin 3; achieves symmetrical clamping via series diode path (VBR + VF). |
| AEC-Q101 qualified | Validated for automotive applications including infotainment, body electronics, and ADAS; ensures reliability under thermal cycling, humidity, and mechanical shock. |
| Low capacitance (45–65 pF) | Minimizes signal integrity degradation on high-speed links up to 100 Mbps; avoids timing skew or rise-time degradation in USB 2.0 or LIN bus designs. |
| e3 Sn termination | Lead-free, RoHS-compliant matte tin plating compatible with standard reflow profiles (peak 260 °C); eliminates Pb-related compliance risk in global automotive supply chains. |
Applications
| Automotive CAN FD Bus Protection | Industrial RS-485 Transceiver Interface |
|---|---|
Use Scenario: Protecting CAN FD nodes in vehicle domain controllers against ESD events during assembly, service, or field operation.

| USB 2.0 Data Line Surge Suppression | Automotive Infotainment Display Link |
Use Scenario: Adding secondary ESD protection to USB 2.0 D+/D− lines in head unit docking stations subject to repeated plug/unplug cycles. IC Role / Device Role / Timing Role: Low-capacitance parallel clamp operating in BiSy mode (pin 3 open) to avoid DC bias conflicts with upstream USB PHY. Use Value: 23–33 pF capacitance at 18 V bias preserves 480 Mbps eye diagram margin; ±30 kV rating exceeds IEC 61000-4-2 Level 4. |
Use Scenario: Protecting MIPI D-PHY or FPD-Link III serializer/deserializer interfaces in digital instrument clusters and center displays. IC Role / Device Role / Timing Role: Two independent clamps (using BiAs mode) on clock and data lanes, sharing ground reference to minimize layout area. Use Value: Enables compact 3-pin SOT-23 placement adjacent to connectors; 150 °C TJ rating supports operation behind dashboards with ambient >105 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/57T | Single-line unidirectional TVS; 36 V VRWM, 600 W PPPM (8/20 μs), 100 pF capacitance. | Requires two devices for dual-line protection; higher capacitance limits speed to ≤10 Mbps. | Select when discrete layout space allows and cost sensitivity outweighs board area constraints. |
| TPD2E001DRYR | Two-line unidirectional ESD array; 5 V VRWM, 200 W PPPM, 12 pF capacitance. | Lower voltage rating suits 3.3 V logic only; insufficient for 24 V automotive data buses. | Choose for low-voltage consumer interfaces (e.g., smartphone dock ports) where ultra-low capacitance is critical. |
Compared with SMAJ36A-E3/57T and TPD2E001DRYR, VGSOT36C-HG3-08 uniquely delivers dual-line 36 V protection in one SOT-23 device with 45–65 pF capacitance-optimizing board space, voltage margin, and high-speed compatibility for automotive and industrial serial links.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT36C-HG3-08?
The VGSOT36C-HG3-08 has a maximum reverse working voltage (VRWM) of 36 V, verified per test condition VR = 36 V at IR = 1 μA. This rating ensures reliable operation on 24 V automotive data buses without leakage-induced signal corruption, making it suitable for CAN FD and LIN physical layers where sustained common-mode voltages approach 27 V.
How does the VGSOT36C-HG3-08 support both unidirectional and bidirectional protection modes?
The VGSOT36C-HG3-08 supports BiAs (bidirectional asymmetrical) mode with pin 3 grounded-protecting two lines independently-and BiSy (bidirectional symmetrical) mode with pin 3 floating-using pins 1 and 2 as a single bidirectional clamp. This dual-mode capability is confirmed in Vishay's Rev. 1.1 datasheet sections 5 and 9, enabling reuse across differential and single-ended interfaces without redesign.
What is the clamping voltage of the VGSOT36C-HG3-08 under a 5.6 A 8/20 μs surge?
Under a 5.6 A 8/20 μs surge (IPPM), the VGSOT36C-HG3-08 clamps to 52–71 V, as specified in the "ELECTRICAL CHARACTERISTICS VGSOT36C" table on page 8 of the datasheet. This value represents the maximum voltage seen by downstream circuitry during worst-case transient events, directly informing system-level overvoltage tolerance design.
Is the VGSOT36C-HG3-08 qualified for automotive applications?
Yes, the VGSOT36C-HG3-08 is AEC-Q101 qualified, as explicitly stated in the "FEATURES" section and "PACKAGE DATA" table of the Vishay document 86325. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock-validating its suitability for under-hood and cabin-mounted automotive electronics.
What is the typical capacitance of the VGSOT36C-HG3-08 at 0 V bias?
The typical capacitance of the VGSOT36C-HG3-08 at 0 V reverse bias and 1 MHz is 55 pF (midpoint of 45–65 pF range), per the "ELECTRICAL CHARACTERISTICS VGSOT36C" table on page 8. This low, well-characterized capacitance ensures minimal signal attenuation and phase shift on high-speed data lines such as USB 2.0 and CAN FD.
