Product details
Overview
GSOT24C-E3-08 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, 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.
For engineers reviewing the GSOT24C-E3-08 datasheet, GSOT24C-E3-08 pinout, GSOT24C-E3-08 application, or GSOT24C-E3-08 equivalent, key selection criteria include clamping voltage at 5 A (41–47 V), low 1 μA leakage at 24 V, 65–80 pF capacitance at 0 V bias, AEC-Q101 qualification readiness, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The GSOT24C-E3-08 implements BiAs-MODE (Bidirectional Asymmetrical) protection: pins 1 and 2 connect to protected signal lines, pin 3 to ground, enabling independent clamping of positive transients (via reverse-biased diodes) and negative transients (via forward conduction). Its asymmetry delivers lower forward clamping (~1.4 V at 5 A) versus reverse clamping (~41–47 V).
It also supports BiSy-MODE (Bidirectional Symmetrical) operation with pin 3 unconnected-pins 1 and 2 forming a single-channel path-yielding matched clamping in both polarities (e.g., 40–48 V at 5 A), suitable for balanced differential interfaces like CAN or RS-422.
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 - compatible with 24 V supply rails and industrial I/O circuits without leakage-induced false triggering. |
| Peak pulse current | 5 A IPPM (8/20 μs) - handles typical lightning-induced surges on 24 V fieldbus lines per IEC 61000-4-5 Level 3. |
| Clamping voltage | 41–47 V VC at 5 A - limits transient voltage to safe levels for downstream 24 V-rated transceivers and microcontrollers. |
| Capacitance | 65–80 pF at 0 V, 20 pF at 12 V - low enough for <10 Mbps data rates in RS-485 or CAN FD applications without signal integrity degradation. |
| Leakage current | 1 μA at 24 V - ensures minimal power loss and no interference with high-impedance sensor inputs or analog monitoring circuits. |
Pinout & Package
SOT-23 package: 3-pin, surface-mount, JEDEC standard footprint (2.8 × 2.35 × 1.15 mm), MSL level 1, lead (Pb)-free e3 Sn plating, UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Signal line 1 input (L1) | Connects to first protected data or I/O line; forms one half of dual-channel BiAs protection path to ground (pin 3). |
| Pin 2 | Signal line 2 input (L2) | Connects to second protected data or I/O line; forms second half of dual-channel BiAs protection path to ground (pin 3). |
| Pin 3 | Ground reference | Must be connected to system ground plane for BiAs operation; left floating for BiSy single-line mode between pins 1 and 2. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional asymmetrical (BiAs) protection | Enables independent clamping of positive/negative transients on two separate lines with optimized forward (1.4 V) and reverse (41–47 V) clamping voltages. |
| Two-mode operation | Supports both dual-line (BiAs) and single-line symmetrical (BiSy) configurations via pin 3 connection state - increases design reuse across interface types. |
| AEC-Q101 qualified variant available | Meets automotive-grade reliability requirements including temperature cycling, HTRB, and ESD stress - suitable for under-hood and body electronics. |
| Low capacitance at operating bias | 20 pF at 12 V reverse bias - preserves signal edge rate and eye diagram integrity in 24 V industrial Ethernet or Profibus links. |
Applications
| Industrial Fieldbus Protection | Automotive Body Control Module I/O |
|---|---|

| 24 V Sensor Interface Protection | Industrial PLC Analog Input Channel |
Use Scenario: Shielding 4–20 mA current loop transmitter outputs from ESD and inductive kickback in factory automation sensors. IC Role / Device Role / Timing Role: Dual-channel BiAs protector on signal+ and signal− lines, referenced to local ground (pin 3). Use Value: Maintains 1 μA leakage at 24 V, avoiding offset errors in precision current-sense amplifiers; 65–80 pF capacitance prevents bandwidth reduction below 100 kHz. | Use Scenario: Protecting 0–10 V analog input channels on modular I/O cards subjected to accidental 24 V miswiring and ESD. IC Role / Device Role / Timing Role: BiAs-mode clamp on high- and low-side inputs, with pin 3 tied to analog ground plane. Use Value: Clamps 24 V transients to ≤47 V within 1 ns, preserving ADC accuracy by preventing input stage saturation or CMOS gate oxide breakdown. |
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 package, same VRWM (24 V), but improved 6 A IPPM and lower 38–45 V clamping at 5 A. | Designed for new designs targeting extended surge margin and lower clamping; not drop-in due to different date code and lifecycle status. | Select VGSOT24C for new designs requiring longer product availability beyond January 2025 end-of-life date of GSOT24C-E3-08. |
| SMF24A | Single-line unidirectional TVS (SOD-123), 24 V VRWM, 100 W PPP, 20 A IPPM - higher surge rating but no dual-line or bidirectional capability. | Requires two devices for dual-line protection; lacks BiSy mode; higher capacitance (100 pF) limits high-speed use. | Use SMF24A only when discrete unidirectional protection suffices and board area allows dual placement. |
Compared with VGSOT24C, GSOT24C-E3-08 offers proven field reliability but lower surge margin; compared with SMF24A, it provides integrated dual-line functionality and lower capacitance at the cost of lower single-pulse energy handling.

FAQ
What is the maximum operating temperature range for GSOT24C-E3-08?
The GSOT24C-E3-08 has a junction temperature range of -55 °C to +150 °C and a storage temperature range of -55 °C to +150 °C. This wide thermal envelope supports deployment in under-hood automotive modules, industrial motor drives, and outdoor telecom equipment where ambient temperatures exceed 85 °C. The device maintains specified clamping performance across this full range.
Can GSOT24C-E3-08 be used in BiSy-mode for CAN bus protection?
Yes, GSOT24C-E3-08 supports BiSy-mode operation for CAN bus protection: leave pin 3 unconnected and use pins 1 and 2 as the differential pair. In this configuration, it delivers matched ±40–48 V clamping at 5 A, meeting ISO 11898-2 transient immunity requirements for physical layer protection. Its 33–40 pF capacitance at 0 V bias avoids signal distortion on CAN FD up to 5 Mbps.
What is the reverse leakage current of GSOT24C-E3-08 at its rated VRWM?
The reverse leakage current of GSOT24C-E3-08 is guaranteed ≤1 μA at 24 V reverse voltage (VR = 24 V), measured at 25 °C. This ultra-low leakage ensures minimal loading on high-impedance 24 V sensor outputs or analog monitoring circuits, preserving measurement accuracy and preventing false triggers in low-power wake-up detection systems.
How does the clamping voltage of GSOT24C-E3-08 compare between BiAs and BiSy modes?
In BiAs mode (pin 3 grounded), GSOT24C-E3-08 clamps at 41–47 V (reverse) and ~1.4 V (forward) at 5 A. In BiSy mode (pin 3 open), clamping is symmetrical at 40–48 V for both polarities at 5 A. The slight difference arises from series impedance contributions in each conduction path - BiSy uses both diodes in series (one forward, one reverse), yielding nearly identical positive/negative clamping.
Is GSOT24C-E3-08 RoHS-compliant and lead-free?
Yes, GSOT24C-E3-08 is RoHS-compliant and lead (Pb)-free, with e3 matte tin (Sn) plating per J-STD-020. The "E3" suffix explicitly denotes this environmental compliance. Its SOT-23 package meets JEDEC standards for reflow soldering up to 260 °C peak temperature, supporting standard Pb-free assembly processes.
