Product details
Overview
VGSOT24-G3-08 from Vishay Semiconductors is a single-line unidirectional ESD protection diode in SOT-23 package, designed to clamp transient voltages on data/signal lines with 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 serves as primary board-level ESD safeguard for USB, HDMI, and industrial I/O interfaces.
For engineers reviewing the VGSOT24-G3-08 datasheet, VGSOT24-G3-08 pinout, VGSOT24-G3-08 application, or VGSOT24-G3-08 equivalent, this page delivers verified electrical specs, BiAs-mode clamping behavior, AEC-Q101 qualification status, thermal limits up to +150 °C junction temperature, and real-world design implications of its 65–80 pF capacitance at 0 V bias.
Technical Context
The VGSOT24-G3-08 implements Bidirectional Asymmetrical (BiAs) protection mode: pin 1 grounded, pin 3 connected to signal line; reverse conduction initiates above 27–33 V breakdown (VBR), while forward clamping holds negative transients near ground via low VF (≤1.2 V at 1 A). Its SOT-23 footprint supports high-density PCB layouts with MSL level 1 moisture sensitivity and 260 °C peak reflow tolerance.
This device operates across –55 °C to +150 °C junction range, sustains 8.4 A peak pulse current (8/20 μs), and delivers 37.5–46 V clamping voltage under full-rated surge-enabling robust protection without compromising signal integrity in 24 V rail systems.
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 |
|---|---|---|---|
| SMAJ24A | Higher VRWM (24 V), but bidirectional configuration and 600 W PPP; larger SMA package (4.5 × 2.7 mm vs. SOT-23's 2.9 × 1.3 mm). | Requires PCB redesign due to different footprint and polarity handling; suited for higher-power surges but less space-efficient. | Select SMAJ24A only when >400 W surge capability is mandatory and board area permits SMA layout. |
| TPD2E001DRYR | Lower VRWM (5.5 V), dual-channel, 10 pF capacitance; 0402 DFN package; rated for ±8 kV HBM only-not ISO 10605 qualified. | Designed for low-capacitance USB/MIPI protection, not 24 V industrial rails; lacks automotive-grade ESD certification. | Choose TPD2E001DRYR for high-speed digital interfaces below 6 V; avoid for 24 V signal lines or automotive ESD compliance. |
Compared with SMAJ24A and TPD2E001DRYR, VGSOT24-G3-08 uniquely balances 24 V system compatibility, ±30 kV automotive-grade ESD immunity, SOT-23 space efficiency, and unidirectional BiAs clamping-making it optimal for industrial and automotive signal-line protection where size, voltage rating, and certification are jointly critical.

FAQ
What is the maximum reverse working voltage (VRWM) of the VGSOT24-G3-08?
The VGSOT24-G3-08 has a VRWM of 24 V, meaning it reliably blocks up to 24 V DC or steady-state signal voltage without significant leakage (≤1 μA). This rating ensures compatibility with 24 V industrial control lines and automotive subsystems, and defines the upper limit before the diode begins conducting in reverse bias-critical for avoiding false triggering during normal operation of the VGSOT24-G3-08.
Does the VGSOT24-G3-08 meet automotive qualification standards?
Yes, the VGSOT24-G3-08 is AEC-Q101 qualified, having passed stress tests for temperature cycling, humidity, mechanical shock, and ESD per automotive reliability requirements. This qualification confirms its suitability for use in body electronics, infotainment, and powertrain-related non-safety-critical modules-providing design assurance that the VGSOT24-G3-08 will perform reliably over vehicle lifetime under harsh environmental conditions.
How does the BiAs-mode operation affect circuit design for the VGSOT24-G3-08?
BiAs-mode means the VGSOT24-G3-08 clamps positive transients at 37.5–46 V (reverse conduction) and negative transients near 0 V (forward conduction), enabling asymmetric protection ideal for single-supply systems. Designers must connect Pin 1 to ground and Pin 3 to the signal line-reversing polarity would disable protection. This behavior makes the VGSOT24-G3-08 especially effective on 24 V biased lines where negative excursions must be tightly limited, unlike symmetrical TVS diodes.
What is the clamping voltage of the VGSOT24-G3-08 under full-rated surge current?
Under an 8.4 A, 8/20 μs surge (its maximum rated IPPM), the VGSOT24-G3-08 clamps to 37.5–46 V. This value-measured across Pin 3 and Pin 1-is the peak voltage imposed on the protected IC during worst-case ESD or lightning-induced surge. Engineers use this spec to verify that the downstream IC's absolute maximum input voltage is not exceeded, ensuring robust system-level protection with the VGSOT24-G3-08.
Is the VGSOT24-G3-08 compatible with lead-free reflow processes?
Yes, the VGSOT24-G3-08 features e3 matte tin terminations and is rated for peak reflow temperatures up to 260 °C per J-STD-020, making it fully compatible with standard lead-free soldering profiles. Its SOT-23 package has MSL level 1 rating, eliminating bake requirements prior to assembly. This ensures reliable interconnect integrity and process compatibility in modern high-volume manufacturing of products using the VGSOT24-G3-08.
