Product details
Overview
ESD7361HT1G from onsemi is a unidirectional ESD protection diode in SOD−323 package, designed for high-speed data line protection with 0.55 pF max junction capacitance, 16 V working peak reverse voltage, and ±15 kV IEC 61000−4−2 contact ESD immunity-used in NFC antenna interfaces and USB 2.0 signal lines.
For engineers reviewing the ESD7361HT1G datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, AEC−Q101 qualification status, clamping behavior at 8 A/16 A TLP pulses, and real-world design implications for high-frequency signal integrity preservation.
Technical Context
This device operates as a single-channel, cathode-grounded unidirectional TVS diode with fast turn-on response to transient overvoltage events. Its low dynamic resistance (0.735 Ω) and sub-1 dB insertion loss up to 5 GHz ensure minimal signal distortion on differential or single-ended high-speed buses.
The ESD7361HT1G implements silicon avalanche clamping triggered by ESD transients exceeding 16.5 V breakdown voltage (at 1 mA), delivering 31 V clamping at 8 A and 34 V at 16 A per TLP testing-enabling robust protection without compromising RF performance in compact wireless modules.

IC Role / Device Role / Timing Role: Series-connected ESD suppressor on each data line, grounded via shortest possible trace. Use Value: Sub-1 dB insertion loss at 480 MHz preserves eye diagram integrity; 31 V clamping protects USB transceivers rated ≤3.6 V. |
| Automotive Infotainment Display Interface | Industrial Sensor Hub Data Bus |
Use Scenario: Shielding MIPI D-PHY lanes connecting display driver IC to SoC in automotive cluster displays. IC Role / Device Role / Timing Role: Per-lane ESD protection placed adjacent to connector or display IC bond pads. Use Value: −55 °C to +125 °C operation supports extended temperature range; SOD−323 footprint fits tight layout constraints. |

IC Role / Device Role / Timing Role: Bidirectional-capable protection (via unidirectional configuration with GND reference) on bus lines. Use Value: 1 A IEC 61000−4−5 surge rating adds secondary lightning-level resilience beyond basic ESD; AEC−Q101 grade assures reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD7361XV2T1G | SOD−523 package (1.2 × 0.8 × 0.6 mm); identical electrical specs but 0.15 mm lower profile and 0.45 mm shorter length. | Better suited for ultra-thin mobile devices where Z-height and board space are constrained. | Select when PCB real estate or mechanical stack-up requires smallest possible footprint. |
| ESD7381HT1G | Bidirectional configuration; same SOD−323 package; 0.65 pF capacitance; 12 V VRWM; 24 V VBR. | Required for AC-coupled or floating signal lines (e.g., audio, legacy RS-232) needing symmetric clamping. | Choose only when bidirectional protection is mandatory-ESD7361HT1G cannot substitute due to unidirectional architecture. |
Compared with ESD7361XV2T1G, the ESD7361HT1G offers greater mechanical robustness and thermal mass in SOD−323, while ESD7381HT1G trades off higher capacitance and lower voltage rating for symmetrical transient suppression-making ESD7361HT1G optimal for cost-sensitive, high-volume 3.3–5 V DC-biased high-speed interfaces.

FAQ
What is the maximum operating temperature for ESD7361HT1G?
The ESD7361HT1G has a specified operating junction temperature range of −55 °C to +125 °C, validated per AEC−Q101 stress testing. This allows deployment in under-hood automotive modules, industrial controllers, and outdoor IoT gateways where ambient temperatures exceed 85 °C. The SOD−323 package's thermal resistance supports sustained operation within this full range when mounted on standard FR-4 with adequate copper pour.
Does ESD7361HT1G support bidirectional ESD protection?
No, ESD7361HT1G is a unidirectional ESD protection diode configured with cathode grounded. It conducts only positive transients to ground and blocks negative excursions beyond its reverse working voltage (16 V). For bidirectional protection, onsemi offers the ESD7381HT1G-a functionally distinct part with symmetrical clamping characteristics and different breakdown parameters.
How does the 0.55 pF capacitance of ESD7361HT1G impact USB 2.0 signal integrity?
The 0.55 pF typical junction capacitance of ESD7361HT1G introduces negligible loading on USB 2.0 differential pairs-measured insertion loss remains below 1 dB up to 5 GHz, preserving eye height and jitter margins. Real-world validation shows <0.5% rise-time degradation on 480 Mbps signals, making it suitable for full-speed and high-speed USB host/peripheral ports without equalization.
Is ESD7361HT1G compliant with automotive qualification standards?
Yes, ESD7361HT1G carries the SZ prefix (as SZESD7361HT1G*) indicating AEC−Q101 qualification and PPAP capability. It undergoes rigorous stress testing-including temperature cycling, HTRB, and ESD robustness-to meet automotive electronics reliability requirements for infotainment, ADAS sensors, and body control modules.
What is the clamping voltage of ESD7361HT1G at 16 A TLP current?
The ESD7361HT1G clamps to a maximum of 34 V at 16 A TLP pulse (Z₀ = 50 Ω, tₚ = 100 ns), per onsemi's published Electrical Characteristics table. This value reflects the voltage measured across the device terminals during standardized transmission line pulse testing and defines the upper bound of voltage exposure imposed on protected circuitry during severe ESD events.
