Product details
Overview
SZSMF05CT2G from onsemi is a 5-line ESD protection diode array in SC-88 package, designed for transient voltage suppression on high-speed data lines. It features 5.0 V reverse working voltage, 6.2–7.2 V breakdown voltage at 1 mA, 9.8 V clamping voltage at 5 A (8 × 20 µs), 80–130 pF line-to-GND capacitance, and 100 W peak power dissipation - ideal for USB, HDMI, and serial port protection in automotive infotainment systems.
For engineers reviewing the SZSMF05CT2G datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ 5.0 V, clamping performance under 5–8 A transients, junction capacitance ≤ 130 pF for signal integrity, AEC-Q101 qualification for automotive use, and SC-88 footprint compatibility with space-constrained PCB layouts.
Technical Context
This monolithic common-anode ESD array integrates five independent cathodes and one shared anode in a single SC-88 package, enabling compact multi-line protection without discrete diode arrays. Its design targets IEC 61000-4-2 Level 4 (±15 kV air / ±8 kV contact) and HBM Class 3B (>8 kV) compliance.
The device operates across −40 °C to +125 °C junction temperature range and supports lead-free reflow up to 260 °C for 10 seconds. Its low leakage (<5 µA at VRWM) and controlled capacitance ensure minimal signal distortion on high-speed interfaces like USB 2.0 and RS-232.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage (VRWM) | 5.0 V - maximum continuous DC or peak operating voltage the protected line can sustain without conduction. |
| Breakdown Voltage (VBR) | 6.2–7.2 V at IT = 1 mA - ensures reliable turn-on before downstream IC damage thresholds are exceeded. |
| Clamping Voltage (VC) | 9.8 V at IPP = 5 A (8 × 20 µs) - limits transient voltage seen by connected ICs during ESD events. |
| Junction Capacitance (CJ) | 80–130 pF at VR = 0 V, f = 1 MHz - balances ESD robustness with signal integrity for <480 Mbps interfaces. |
| Peak Pulse Power (PPK) | 100 W (8 × 20 µs waveform) - sustains high-energy surges without failure in automotive and industrial environments. |
| ESD Rating | HBM >8 kV, MM >400 V, IEC 61000-4-2 ±15 kV (air), ±8 kV (contact) - meets stringent system-level immunity requirements. |
| Operating Temperature | −40 °C to +125 °C - supports under-hood and infotainment module deployment in automotive applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMF05CT1G | Same electrical specs and SC-88 package, but lacks SZ-prefix AEC-Q101 qualification and PPAP capability. | Targeted at commercial-grade computing and telecom; not validated for automotive temperature cycling or humidity testing. | Select SMF05CT1G only for non-automotive applications where cost sensitivity outweighs qualification requirements. |
| TPD4E05U06DQAR | Lower capacitance (5.5 pF typical), higher VRWM (5.5 V), but rated for 4-line protection only and uses DQFN-10 package. | Preferred for ultra-high-speed interfaces (e.g., USB 3.0, PCIe); requires PCB redesign due to different footprint and pin count. | Choose TPD4E05U06DQAR when signal bandwidth exceeds 1 GHz and board space permits larger 10-pin package. |
Compared with SMF05CT1G and TPD4E05U06DQAR, SZSMF05CT2G uniquely delivers AEC-Q101 validation, 5-line integration in SC-88, and balanced 80–130 pF capacitance - making it the optimal choice for automotive serial bus protection where qualification, footprint, and multi-line efficiency are jointly critical.

FAQ
What is the primary function of the SZSMF05CT2G?
The SZSMF05CT2G is a 5-line ESD protection diode array designed to safeguard sensitive electronic interfaces from electrostatic discharge and transient voltage events. It functions by clamping surge voltages above its breakdown threshold (6.2–7.2 V) to a safe level (9.8 V at 5 A), diverting current to ground via its common anode. This protects downstream ICs such as USB transceivers, UART controllers, and automotive sensor interfaces without disrupting normal signal operation.
Does the SZSMF05CT2G meet automotive qualification standards?
Yes, the SZSMF05CT2G is AEC-Q101 qualified and PPAP capable, confirming its suitability for automotive applications. It has undergone rigorous stress testing including temperature cycling, humidity bias, and mechanical shock - all aligned with automotive electronics reliability requirements. The "SZ" prefix explicitly denotes devices manufactured under automotive-specific process controls and site qualifications, distinguishing it from commercial variants like SMF05CT1G.
What is the significance of the "T2G" suffix in SZSMF05CT2G?
The "T2G" suffix indicates a Pb-free SC-88 package supplied in tape-and-reel format with an alternate orientation (T2) compared to the standard T1 configuration. This orientation affects component placement direction during automated pick-and-place assembly but does not alter electrical performance, pinout, or thermal characteristics. Both T1G and T2G versions share identical specifications, AEC-Q101 qualification, and mechanical dimensions.
How does the SZSMF05CT2G compare to single-line TVS diodes in multi-line protection designs?
The SZSMF05CT2G integrates five independent ESD protection paths into a single SC-88 package, eliminating the need for five discrete diodes and associated PCB real estate, routing complexity, and bill-of-materials overhead. Its monolithic common-anode structure ensures matched clamping behavior across all lines and reduces parasitic inductance versus discrete layouts - improving consistency during multi-pin ESD events such as IEC 61000-4-2 contact discharge.
Can the SZSMF05CT2G be used on high-speed differential interfaces like HDMI or USB 2.0?
Yes, the SZSMF05CT2G is suitable for USB 2.0 and other high-speed single-ended or quasi-differential interfaces, with junction capacitance specified at 80–130 pF per line at 1 MHz. While not optimized for >1 Gbps differential protocols (e.g., USB 3.0 or HDMI 2.0), its clamping performance, low leakage (<5 µA), and 5.0 V VRWM make it effective for protecting D+, D−, VBUS, ID, and GND lines in USB 2.0 implementations without degrading eye diagram integrity.
