Product details
Overview
SMF4L10CA-7 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in DO-219AA package, designed for high-energy ESD and surge protection on data lines and power rails. It features 10V working peak reverse voltage (VRWM), 11.1V minimum breakdown voltage (VBR), 17V maximum clamping voltage (VC) at 23.5A peak pulse current, and 400W peak pulse power dissipation (10/1000µs waveform). It is used in automotive infotainment interfaces and USB-C port protection.
For engineers reviewing the SMF4L10CA-7 datasheet, SMF4L10CA-7 pinout, SMF4L10CA-7 application, or SMF4L10CA-7 equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, IEC 61000-4-2 ±30kV air/contact ESD capability, bi-directional symmetry for AC-coupled signal lines, and thermal resistance (RθJA = 96°C/W) under standard PCB layout conditions.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with identical VBR min/max (11.1V / 12.3V) and VC (17V) in either direction, enabling robust protection of differential or AC-signaled paths without polarity dependency. Its sub-5ns response time ensures suppression before sensitive downstream circuitry sustains damage during fast transients.
The device leverages avalanche breakdown in silicon PN junctions to divert surge energy away from protected nodes. Its 1.0W DC power dissipation and 96°C/W junction-to-ambient thermal resistance are specified for 1"×1" FR-4 board with 2 oz. copper, defining safe continuous operating limits under steady-state leakage or low-duty-cycle surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 10V - Maximum continuous reverse voltage before significant leakage; sets upper limit for normal operation on protected line. |
| VBR (min/max) | 11.1V / 12.3V - Breakdown initiates within this range at 1mA test current; defines onset of clamping action. |
| VC @ IPP | 17V at 23.5A - Clamping voltage during 10/1000µs surge; must stay below protected IC's absolute max rating. |
| PPK | 400W - Peak pulse power handling per 10/1000µs waveform; determines survivability against IEC 61000-4-5 Level 4 surges. |
| ESD Rating | ±30kV contact / ±30kV air per IEC 61000-4-2 - Validates immunity to human-body-model discharges in handheld and automotive environments. |
| RθJA | 96°C/W - Junction-to-ambient thermal resistance on standard 1"×1" FR-4 board; used to calculate temperature rise under DC bias or repetitive pulses. |
Pinout & Package
Package: DO-219AA - Surface-mount, flat leadless plastic package (2.80mm × 1.90mm × 0.60mm), RoHS-compliant matte tin finish, moisture sensitivity level 1, weight ≈0.016g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional terminals | No polarity marking; identical electrical behavior in both directions - enables placement without orientation check on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power (10/1000µs) | Supports IEC 61000-4-5 Level 4 (4kV) surge immunity on 12V automotive power rails with margin. |
| ±30kV IEC 61000-4-2 ESD protection | Eliminates need for external ESD diodes in USB 2.0/3.2, HDMI, and CAN FD interfaces. |
| Sub-5ns response time (bi-directional) | Clamps transients before propagation delay of typical interface ICs (<10ns), preventing latch-up or gate oxide damage. |
| DO-219AA footprint | 0.6mm height enables ultra-thin designs in space-constrained automotive modules and portable electronics. |
Applications
| Automotive Infotainment Display Interface | USB-C Power Delivery Port Protection |
|---|---|
|
Use Scenario: Protecting LVDS or FPD-Link III video data lines between head unit and digital dashboard display against load dump and ESD events. IC Role / Device Role: Bi-directional TVS placed differential-pair-wise across each signal lane, referenced to local ground plane. Use Value: 17V clamping ensures signal integrity remains intact below display driver IC's 18V abs max rating while surviving ±30kV contact discharge. |
Use Scenario: Safeguarding CC, VBUS, and SBU pins in automotive USB-C receptacles exposed to hot-plug and cable-induced surges. IC Role / Device Role: Discrete TVS mounted adjacent to connector, with minimal trace length to reduce inductance and preserve clamping performance. Use Value: Symmetric breakdown allows single device per pin without polarity concern; 10V VRWM aligns with USB PD 3.0 VBUS monitoring thresholds. |
| Industrial CAN FD Transceiver Interface | Smartphone Camera Module Flex Cable |
|
Use Scenario: Guarding CAN_H/CAN_L differential pair against ISO 16750-2 jump-start and alternator load dump transients in vehicle ECUs. IC Role / Device Role: Bi-directional TVS placed across differential pair, with low capacitance preserving signal edge rate up to 5Mbps. Use Value: 17V VC stays below transceiver's common-mode range limit (±36V) while limiting differential overshoot to <2V peak. |
Use Scenario: Shielding MIPI CSI-2 data lanes on camera flex cables from ESD during assembly and field service in consumer handsets. IC Role / Device Role: Ultra-low-profile TVS mounted directly at connector entry point to minimize stub inductance. Use Value: 0.6mm height fits beneath shield cans; ±30kV air discharge rating prevents pixel corruption or sensor reset during handling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA-TP (Microchip) | Same VRWM (10V), but higher VC (17.5V), lower PPK (400W same), DO-214AC package (larger, 2.79mm height). | Less suitable for ultra-thin automotive modules due to 4.6× larger board area and 4.6× greater height. | Select when legacy DO-214AC footprint compatibility is required and board height >1.0mm is acceptable. |
| SP1003-010 (Bourns) | Same VRWM (10V), lower VC (16.5V), same ESD rating, but SOD-323 package (0.9mm × 1.3mm, 0.9mm height) and lower PPK (200W). | Insufficient for IEC 61000-4-5 Level 4 surge; limited to ESD-only use cases like smartphone buttons or touchscreens. | Select only for space-constrained ESD-only protection where surge immunity is not required. |
Compared with SMAJ10CA-TP and SP1003-010, SMF4L10CA-7 delivers optimal balance of low profile (0.6mm), industry-leading 400W surge capability in DO-219AA, and symmetric bi-directional clamping-making it uniquely suited for next-generation automotive and portable USB-C designs demanding both height and surge margin.

FAQ
What is the polarity configuration of SMF4L10CA-7?
SMF4L10CA-7 is a bi-directional TVS diode with no cathode band marking. Its symmetrical construction provides identical breakdown and clamping characteristics in both forward and reverse directions, eliminating orientation constraints during placement and enabling use on AC-coupled or differential signal lines without polarity verification.
Does SMF4L10CA-7 meet AEC-Q200 requirements?
SMF4L10CA-7 itself is not AEC-Q200 qualified; however, Diodes offers automotive-grade variants with Q-suffix (e.g., SMF4L10CAQ-7) that are fully qualified to AEC-Q200, manufactured in IATF 16949-certified facilities, and supported by PPAP documentation. Standard SMF4L10CA-7 is intended for commercial and industrial applications.
How does the DO-219AA package affect thermal performance?
The DO-219AA package achieves RθJA = 96°C/W on a 1"×1" FR-4 board with 2 oz. copper, enabled by its low-profile thermal path from die to solder joint. Its 0.6mm height and 1.90mm × 2.80mm footprint allow efficient heat spreading into the PCB, making it more thermally effective per unit volume than taller packages like DO-214AC despite smaller pad area.
Can SMF4L10CA-7 be used in place of unidirectional TVS diodes?
No-SMF4L10CA-7 is strictly bi-directional and lacks anode/cathode asymmetry. It must not replace unidirectional TVS diodes (e.g., SMF4L10A-7) in DC-biased circuits such as 12V power rail protection, where reverse blocking is required. Using it in such roles risks forward conduction and failure during normal operation.
