Product details
Overview
GSOT24C-HG3-08 from Vishay Semiconductors is a two-line bidirectional asymmetrical ESD protection diode in SOT-23 package, rated for ±30 kV IEC 61000-4-2 contact/air discharge, 24 V reverse stand-off voltage (VRWM), 5 A peak pulse current (IPPM), and 235 W peak pulse power (PPP). It protects high-speed data lines such as USB 2.0 or RS-485 interfaces against transient overvoltage events.
For engineers reviewing the GSOT24C-HG3-08 datasheet, GSOT24C-HG3-08 pinout, GSOT24C-HG3-08 application, or GSOT24C-HG3-08 equivalent, this page delivers verified electrical characteristics, BiAs-mode and BiSy-mode configuration guidance, clamping behavior under 5 A surge, capacitance at 24 V bias, and AEC-Q101-qualified green packaging details.
Technical Context
The GSOT24C-HG3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: with pin 3 grounded and pins 1/2 connected to protected signal lines, it provides distinct forward (VF ≈ 1.4 V @ 5 A) and reverse (VC ≈ 41–47 V @ 5 A) clamping voltages. Its asymmetry enables optimized protection for unidirectional data buses where ground-referenced transients dominate.
In BiSy-MODE (single-line symmetrical), pin 3 is left unconnected while pins 1 and 2 form a bipolar path; this yields matched positive/negative clamping (VC ≈ 40–48 V @ 5 A) and 33–40 pF capacitance at 0 V, suitable for balanced differential interfaces like CAN FD or LVDS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ESD immunity | ±30 kV contact & air discharge per IEC 61000-4-2 - meets industrial and automotive ESD robustness requirements without external shielding. |
| Reverse stand-off voltage | 24 V VRWM - supports 24 V nominal systems (e.g., industrial control I/O, PoE-powered devices) without leakage-induced false triggering. |
| Peak pulse current | 5 A per line (IEC 61000-4-5, 8/20 μs) - handles typical lightning-induced surges on 24 V sensor or actuator lines. |
| Clamping voltage | 41–47 V @ 5 A (reverse), 1.4 V @ 5 A (forward) - limits transient voltage to safe levels for 24 V logic and analog front-ends. |
| Capacitance | 65–80 pF @ 0 V, 20 pF @ 12 V - low enough for 10 Mbps RS-485 or 480 Mbps USB 2.0 without signal integrity degradation. |
| Operating temperature | −55 °C to +150 °C - qualified for under-hood automotive, factory automation, and outdoor telecom equipment. |
| AEC-Q101 qualified | Yes - validated for automotive electronics per stress test requirements including HBM > 8 kV (Class H3B). |
Pinout & Package
SOT-23 package (JEDEC TO-236AB), 3-pin surface-mount, e3 Sn plating, MSL level 1, 8.8 mg weight, UL 94 V-0 molding compound. Compatible with standard reflow profiles (peak ≤ 260 °C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Line 1 anode / cathode | Connects to first protected signal line (L1); forms one half of dual-channel ESD path to ground (pin 3) or symmetrical path to pin 2. |
| Pin 2 | Line 2 anode / cathode | Connects to second protected signal line (L2); identical structure to pin 1 - enables simultaneous two-line protection in BiAs mode. |
| Pin 3 | Ground reference | Must be connected to system ground in BiAs mode; left floating in BiSy mode to enable single-line symmetrical clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Two-line ESD protection | Single SOT-23 device protects two independent data/signal lines - reduces BOM count and PCB area vs. dual discrete diodes. |
| Bidirectional asymmetrical (BiAs) operation | Enables low forward-voltage clamping (<1.4 V) for negative transients while maintaining high reverse breakdown (27–33 V) for positive surges - ideal for ground-referenced interfaces. |
| Configurable BiSy mode | Unconnected pin 3 allows use as single-line symmetrical protector - supports differential standards (CAN, RS-422) without redesigning layout. |
| Low leakage at 24 V | IR ≤ 1 μA @ VR = 24 V - prevents DC loading on 24 V sensor supply rails or high-impedance analog inputs. |
| Green RoHS-compliant packaging | HG3 suffix indicates lead-free, halogen-free, green-compliant SOT-23 with Sn plating - satisfies IPC-1752 and EU RoHS Directive 2011/65/EU. |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
Use Scenario: Protecting 24 V analog output channels (4–20 mA transmitters) and digital I/O lines from ESD during field wiring or maintenance. IC Role / Device Role / Timing Role: Two-line ESD clamp placed at connector entry point, shunting transients to chassis ground before reaching MCU GPIO or DAC. Use Value: Prevents latch-up or permanent damage to 24 V-tolerant analog front-ends while maintaining <1 μA leakage at operating voltage. | Use Scenario: Shielding LIN bus and switch inputs in door modules exposed to human touch and cable harness coupling. IC Role / Device Role / Timing Role: Bidirectional asymmetrical protector on LIN data line (pin 1) and wake-up input (pin 2), both referenced to vehicle ground (pin 3). Use Value: Delivers ±30 kV ESD immunity without degrading 20 kbps LIN signal rise time due to 65–80 pF capacitance at 0 V. |
| RS-485 Transceiver Protection | USB 2.0 Host Port ESD Guard |
Use Scenario: Safeguarding full-duplex RS-485 transceivers in building automation controllers subjected to cable discharge events. IC Role / Device Role / Timing Role: Dual-channel clamp on A/B differential pair, configured in BiAs mode with common ground return (pin 3) to suppress common-mode surges. Use Value: Limits clamping voltage to ≤47 V during 5 A transients - stays below RS-485 receiver absolute maximum rating (±12 V common-mode + 6 V differential margin). | Use Scenario: Adding secondary ESD protection on USB 2.0 D+/D− lines downstream of integrated transceiver ESD structures. IC Role / Device Role / Timing Role: Two-line protector placed between connector and PHY, using BiSy mode (pin 3 open) to provide matched clamping on differential pair. Use Value: 33–40 pF capacitance at 0 V ensures <1% signal distortion at 480 Mbps; 1.4 V forward clamping prevents data corruption during negative ESD pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VGSOT24C | Successor device with identical SOT-23 footprint, same VRWM (24 V), but improved PPP (260 W vs. 235 W) and lower IR (0.5 μA max). | End-of-life replacement; supports same BiAs/BiSy configurations and thermal profile. | Select VGSOT24C for new designs requiring extended product lifecycle beyond January 2025. |
| SMF24A | Single-line 24 V TVS diode (SOD-123), 5.5 A IPPM, 320 W PPP, 100 pF @ 0 V - no dual-line capability. | Requires two devices for two-line protection; higher capacitance limits use in >10 Mbps interfaces. | Use SMF24A only when board space allows dual placement and signal bandwidth is ≤5 Mbps. |
