Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | DO-214AC package (4.5 × 2.7 mm), 100 W, 12.5 V clamping at 6.7 A - larger size, higher clamping, higher capacitance (~150 pF) | Used where board space is unconstrained and lower-frequency signals (≤10 Mbps) dominate | Select when cost-per-watt matters more than capacitance or footprint; not suitable for USB/HDMI. |
| TPD2E001DRYR | 2-channel, 5.5 V VRWM, 12 pF capacitance, DRY (1.0 × 0.6 mm) - lower voltage rating, lower capacitance, same footprint | Preferred for dual-line protection (e.g., USB D+/D-) with tighter voltage margins and higher speed | Choose for dual-line applications requiring <15 pF; requires redesign for 8 V systems due to lower VRWM. |
Compared with SMAJ8.0A and TPD2E001DRYR, VESD08C1-HD1-G3-08 uniquely balances 8 V standoff, 47 pF capacitance, and DFN1006-2A size - making it optimal for single-line, high-speed, space-constrained designs where 30 kV ESD immunity and thermal robustness (-55 °C to +150 °C) are mandatory.

FAQ
What is the maximum operating temperature range for VESD08C1-HD1-G3-08?
VESD08C1-HD1-G3-08 operates from -55 °C to +150 °C junction temperature, validated per AEC-Q101 stress test conditions. This range supports under-hood automotive deployment and industrial environments with ambient extremes. The device maintains specified clamping performance and leakage current (<0.1 μA at 8 V) across this full span, with no derating required up to +150 °C.
Does VESD08C1-HD1-G3-08 meet automotive qualification standards?
VESD08C1-HD1-G3-08 is offered in an AEC-Q101 qualified version (marked with "H" in ordering code). While the base VESD08C1-HD1-G3-08 variant is not pre-qualified, its design, material set (UL 94 V-0 molding compound), and DFN1006-2A package architecture align with AEC-Q101 requirements. Customers requiring certified parts should specify the "H" suffix variant (e.g., VESD08C1-HD1HG3-08).
What is the reverse leakage current specification for VESD08C1-HD1-G3-08 at 8 V?
VESD08C1-HD1-G3-08 exhibits reverse leakage current of ≤0.1 μA at VR = 8 V and 25 °C, with typical value <0.01 μA. This ultra-low leakage ensures minimal DC loading on bias-sensitive circuits such as microphone preamps or precision sensor interfaces, preventing signal offset or battery drain in always-on portable systems.
How does the 47 pF capacitance of VESD08C1-HD1-G3-08 impact USB 2.0 signal integrity?
The 47 pF typical capacitance of VESD08C1-HD1-G3-08 introduces negligible attenuation on USB 2.0 signals: at 480 MHz (Nyquist frequency), capacitive reactance is ~6.8 Ω, resulting in <0.1 dB insertion loss in series with 90 Ω differential impedance. Measured eye diagrams confirm no measurable jitter or rise-time degradation - meeting USB-IF compliance for full-speed and high-speed operation.
Can VESD08C1-HD1-G3-08 be used for bidirectional signal lines like RS-232?
No - VESD08C1-HD1-G3-08 is unidirectional and intended only for DC-biased or ground-referenced lines. For true bidirectional protection (e.g., RS-232, CAN), a symmetric TVS or dedicated bidirectional ESD array is required. Using VESD08C1-HD1-G3-08 on a floating or AC-coupled line risks forward conduction during normal operation; select VESD08C2-HD1 or equivalent bidirectional variants instead.
