Product details
Overview
SZSMF05CT1G from onsemi is a 5-line ESD protection diode array in SC-88 package, featuring 5.0 V reverse working voltage, 7.2 V max breakdown voltage, and 9.8 V clamping voltage at 5 A (8 × 20 µs), designed for transient suppression on high-speed data lines in automotive and computing interfaces.
For engineers reviewing the SZSMF05CT1G datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM ≥ 5 V, clamping performance under 5–8 A surge, IEC 61000-4-2 ±15 kV air/±8 kV contact compliance, and SC-88 footprint compatibility with multi-line signal protection 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 protection of parallel signal paths without cross-coupling. It operates across −40 °C to +125 °C junction temperature and supports Pb-free reflow up to 260 °C for 10 seconds.
The device meets AEC-Q101 qualification for automotive use and delivers 100 W peak power dissipation (8 × 20 µs waveform) with ≤130 pF line-to-GND capacitance at 0 V bias and 1 MHz - critical for USB 2.0, HDMI, and CAN FD signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Working Voltage | 5.0 V - sets maximum continuous DC operating voltage before leakage rises significantly |
| Breakdown Voltage | 6.2–7.2 V at 1 mA - defines onset of avalanche conduction during transients |
| Clamping Voltage | 9.8 V at 5 A (8 × 20 µs) - limits voltage seen by protected IC during ESD event |
| Peak Pulse Current | 8.0 A (8 × 20 µs) - determines maximum surge energy the device can absorb per pulse |
| Junction Capacitance | 80–130 pF at 0 V, 1 MHz - impacts signal rise time and insertion loss on high-speed lines |
| ESD Rating | HBM Class 3B (>8 kV), IEC 61000-4-2 ±15 kV air / ±8 kV contact - certifies robustness against real-world electrostatic discharge |
| Package | SC-88 (Case 419B, Style 24) - 2.00 × 1.25 × 0.90 mm, 0.65 mm pitch, surface-mount compatible |
Pinout & Package

|---|---|
Use Scenario: Protecting LVDS or FPD-Link video signals between head unit and display in vehicles exposed to load dump and ESD. IC Role / Device Role / Timing Role: ESD transient suppressor on bidirectional differential pairs, clamping surges before they reach serializer/deserializer ICs. Use Value: Prevents latch-up or gate oxide damage in downstream SerDes ICs while maintaining <130 pF loading to preserve 480 Mbps USB 2.0 eye diagram integrity. | Use Scenario: Shielding D+ and D− lines of USB 2.0 ports in notebooks and docking stations from human-body ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS array placed directly at connector, shunting ESD current to ground before reaching USB PHY. Use Value: Achieves ±15 kV air / ±8 kV contact IEC 61000-4-2 compliance without degrading signal edge rate or causing packet errors. |
| Industrial Ethernet PHY Ports | Automotive CAN FD Bus Nodes |
Use Scenario: Safeguarding MDI pins of 10/100BASE-TX Ethernet PHYs in factory automation controllers subjected to cable discharge events. IC Role / Device Role / Timing Role: Common-anode clamp on transformer-coupled TX+/TX− and RX+/RX− pairs, referenced to isolated PHY ground. Use Value: Limits clamped voltage to <10 V during 8 A transients, preventing PHY receiver saturation and maintaining link stability under EMC stress. | Use Scenario: Protecting CAN_H/CAN_L lines in automotive ECUs where ESD immunity must meet ISO 10605 (±25 kV) and ISO 16750-2 requirements. IC Role / Device Role / Timing Role: Dual-line ESD suppressor with matched capacitance on both bus lines, preserving common-mode noise rejection. Use Value: Provides symmetric clamping (<10 V deviation between lines) and <130 pF loading per line to avoid CAN FD bit timing skew above 5 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ESD5V3U2U-2/TR | Lower clamping voltage (7.5 V @ 5 A), higher capacitance (150 pF), SOT-23-6 package | Better for ultra-low-voltage logic but less suitable for high-speed interfaces due to higher CJ | Select when tighter clamping is prioritized over signal integrity on sub-100 Mbps lines |
| TPD2E001DRYR | Single-line design (2-channel), lower peak power (50 W), same SC-70-6 footprint | Limited to dual-line protection; lacks 5-line integration and 100 W surge rating | Choose only when board space allows separate placement and 5-line consolidation is unnecessary |
Compared with ESD5V3U2U-2/TR and TPD2E001DRYR, SZSMF05CT1G uniquely combines 5-line integration, 100 W surge capability, and IEC 61000-4-2 compliance in SC-88 - making it optimal for space-constrained automotive and computing interfaces requiring consolidated, high-energy ESD protection.

FAQ
What is the reverse working voltage specification for SZSMF05CT1G?
The SZSMF05CT1G has a reverse working voltage (VRWM) of 5.0 V, meaning it can continuously block up to 5.0 V DC or peak AC voltage without significant leakage current. This value ensures compatibility with 3.3 V and 5 V logic systems while providing margin before avalanche conduction begins at 6.2–7.2 V. The SZSMF05CT1G datasheet specifies this parameter under standard test conditions (TJ = 25 °C).
Does SZSMF05CT1G meet automotive qualification standards?
Yes, SZSMF05CT1G is AEC-Q101 qualified and PPAP capable, confirming its suitability for automotive applications including infotainment, ADAS camera links, and body control modules. The "SZ" prefix explicitly denotes compliance with automotive-specific site and process controls. Its operating junction temperature range of −40 °C to +125 °C and UL 94 V-0 flammability rating further validate its use in harsh vehicle environments.
How many signal lines does SZSMF05CT1G protect, and what is its pin configuration?
SZSMF05CT1G protects five independent signal lines using a monolithic common-anode structure in SC-88 (6-pin) package. Pin 1, 3, 4, 5, and 6 are individual cathodes; Pin 2 is the shared anode. This configuration allows compact protection of parallel data buses like USB D+/D− plus auxiliary lines, all within a 2.00 × 1.25 mm footprint.
What is the clamping voltage of SZSMF05CT1G under a 5 A transient?
The clamping voltage of SZSMF05CT1G is 9.8 V when subjected to a 5 A, 8 × 20 µs surge waveform. This value represents the maximum voltage imposed on the protected line during such a transient, ensuring downstream ICs (e.g., USB PHYs or CAN transceivers) remain below their absolute maximum ratings. The SZSMF05CT1G achieves this while maintaining ≤130 pF junction capacitance per line.
Is SZSMF05CT1G compatible with lead-free reflow soldering processes?
Yes, SZSMF05CT1G is supplied in a Pb-free SC-88 package rated for lead-free reflow soldering at 260 °C for 10 seconds, complying with JEDEC J-STD-020 moisture sensitivity level (MSL) requirements. Its termination finish and package construction support standard SMT assembly without risk of popcorning or delamination, and it meets RoHS Directive 2011/65/EU.
