Product details
Overview
VGSOT24C-G3-08 from Vishay Semiconductors is a two-line unidirectional ESD protection diode in SOT-23 package, featuring common-anode configuration, 24 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 protects high-speed data lines such as USB 2.0 and HDMI interfaces against electrostatic discharge.
For engineers reviewing the VGSOT24C-G3-08 datasheet, VGSOT24C-G3-08 pinout, VGSOT24C-G3-08 application, or VGSOT24C-G3-08 equivalent, this page delivers verified electrical characteristics, BiAs/BiSy dual-mode operation details, clamping behavior under transient stress, and AEC-Q101-qualified alternatives for automotive and industrial interface protection.
Technical Context
The VGSOT24C-G3-08 implements a dual-channel, common-anode ESD protection architecture enabling BiAs-mode (bidirectional asymmetrical) operation with separate forward and reverse clamping paths - 1.7 V forward clamping at 8.4 A and 46 V reverse clamping at same current. Pin 3 serves as shared cathode/anode reference depending on mode.
In BiSy-mode (single-line bidirectional symmetrical), pins 1 and 2 form a back-to-back diode pair with pin 3 left unconnected, delivering matched ±40–48 V clamping at 8.4 A and 33–40 pF capacitance at 0 V bias - optimized for balanced signal integrity in RS-485 or CAN FD transceivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - maximum continuous reverse working voltage before leakage exceeds 1 μA; sets upper limit for protected line DC bias. |
| VBR (min) | 27 V - guaranteed reverse breakdown threshold at 1 mA; ensures reliable turn-on during transients above system operating voltage. |
| VC @ IPPM | 37.5–46 V - clamped voltage during 8.4 A, 8/20 μs surge; defines worst-case overvoltage seen by downstream ICs. |
| CD @ 0 V | 65–80 pF - low inter-electrode capacitance preserves signal integrity on 480 Mbps USB 2.0 or 100 Mbps Ethernet PHY lines. |
| ESD immunity | ±30 kV contact/air - meets IEC 61000-4-2 Level 4 and ISO 10605 automotive requirements without external filtering. |
| TJ max | +150 °C - supports under-hood automotive placement and extended industrial temperature operation. |
| PPPM (8/20 μs) | 400 W - peak pulse power handling capacity; determines survivability against lightning-induced surges per IEC 61000-4-5. |
