Product details
Overview
SMF4L6.0CA-7 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in DO-219AA package, designed for ESD and surge protection on low-voltage signal and power lines. It features 6.0V working peak reverse voltage (VRWM), 10.3A maximum reverse surge current (IRSM), 10.3V clamping voltage (VC) at 38.3A peak pulse current, and ±30kV IEC61000-4-2 ESD immunity - used in automotive battery contacts and USB interface protection.
For engineers reviewing the SMF4L6.0CA-7 datasheet, SMF4L6.0CA-7 pinout, SMF4L6.0CA-7 application, or SMF4L6.0CA-7 equivalent, key selection criteria include clamping voltage margin vs. protected IC VCC, bi-directional symmetry for AC-coupled lines, DO-219AA thermal performance under 400W 10/1000µs pulses, and AEC-Q200 readiness for automotive-grade deployment.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with breakdown voltage VBR min/max of 6.67V/7.37V at 10mA test current, enabling robust overvoltage clamping on differential or floating lines. Its sub-5ns response time ensures suppression before downstream IC damage occurs during fast transients like ISO 7637-2 pulse 1/2a.
The device delivers 400W peak pulse power (10/1000µs waveform) with 1.0W DC steady-state dissipation, supported by RθJA = 96°C/W and RθJC = 18°C/W thermal resistance - optimized for compact PCB layouts with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 6.0V - Maximum continuous reverse operating voltage before clamping begins; sets upper limit for protected line voltage. |
| VBR (min/max) | 6.67V / 7.37V @ 10mA - Confirmed breakdown range ensures reliable turn-on without premature conduction. |
| VC @ IRSM | 10.3V @ 38.3A - Clamping voltage during 10/1000µs surge; defines worst-case stress on downstream ICs. |
| PPK | 400W - Peak pulse power handling per JEDEC-standard 10/1000µs waveform; validates surge survivability. |
| ESD Rating | ±30kV air / ±30kV contact per IEC61000-4-2 - Ensures immunity to human-body-model discharges in handheld and automotive environments. |
| Package | DO-219AA - Surface-mount, low-profile (0.6mm typical height), thermally efficient package with 1.9mm × 2.8mm footprint. |
| Operating Temp | –55°C to +175°C - Supports under-hood automotive and industrial applications without derating. |
Pinout & Package
DO-219AA package: bi-directional device with no cathode band; symmetrical two-terminal construction. Terminals are matte tin-finished copper alloy leads, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Bi-directional conduction allows clamping of positive and negative surges without polarity sensitivity. |
| Case / Body | Thermal conduction path | Molded plastic body with RθJC = 18°C/W enables direct heat transfer to PCB copper pour or thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse rating | Validated for 10/1000µs waveform - withstands high-energy load dump and inductive switching events in 12V automotive systems. |
| ±30kV ESD protection | Fully compliant with IEC61000-4-2 Level 4 - eliminates need for external ESD diodes on USB, CAN, or sensor interfaces. |
| Sub-5ns response time | Clamps transients within 5ns (bi-directional) - faster than most microcontroller I/O pin response, preventing latch-up or gate oxide damage. |
| DO-219AA thermal efficiency | RθJC = 18°C/W - enables >1.5× higher power dissipation vs. SMA packages at same board area, reducing thermal derating. |
| AEC-Q200 readiness | Manufactured in IATF 16949-certified facilities; qualified to JEDEC reliability standards - supports PPAP documentation for automotive programs. |
Applications
| Automotive Battery Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting 12V battery feed lines against load dump (ISO 7637-2 Pulse 5a) and jump-start transients. IC Role / Device Role / Timing Role: Primary clamping element placed at module input, shunting surge energy to ground before reaching PMIC or MCU power rails. Use Value: 10.3V clamping voltage ensures protected devices see <12V stress during 38.3A surge, preserving 13.5V-rated input stages. |
Use Scenario: Safeguarding USB 2.0 D+/D− lines against ESD events during cable insertion and hot-plug operations. IC Role / Device Role / Timing Role: Bi-directional TVS placed directly at connector, providing symmetrical clamping for differential signaling integrity. Use Value: 6.0V VRWM allows full 3.3V data swing while clamping ±30kV ESD to <10.3V, preventing PHY damage without signal distortion. |
| Industrial Sensor Interface | RS-485 Transceiver Protection |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from induced surges in factory-floor wiring harnesses. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted at sensor PCB edge, limiting voltage excursion on op-amp output or ADC input. Use Value: DO-219AA's typical junction capacitance <100pF avoids bandwidth degradation in 10kHz sensor signals. |
Use Scenario: Protecting RS-485 transceivers (e.g., MAX1487) from lightning-induced surges on long-distance twisted-pair cables. IC Role / Device Role / Timing Role: Bi-directional clamping between A/B lines and ground, absorbing common-mode and differential-mode transients. Use Value: 400W pulse rating sustains multiple 10/1000µs surges up to 38.3A without parametric shift, ensuring field-reliability. |

FAQ
What is the difference between SMF4L6.0A and SMF4L6.0CA?
SMF4L6.0A is unidirectional (cathode-banded), intended for DC-biased lines like power rails; SMF4L6.0CA is bi-directional (no cathode band), designed for AC or floating signals such as USB D+/D− or RS-485 A/B. Their clamping behavior, VRWM, and VBR specs are identical, but polarity handling differs fundamentally.
Can SMF4L6.0CA-7 replace P6SMB6.0CA in existing designs?
No - P6SMB6.0CA uses DO-214AA (SMB) package with larger footprint (4.58mm × 3.94mm) and higher RθJA (~50°C/W). SMF4L6.0CA-7's DO-219AA (2.8mm × 1.9mm) offers 40% smaller area and superior thermal resistance (RθJA = 96°C/W), requiring PCB layout revision and thermal validation.
Does this part meet AEC-Q200 requirements?
SMF4L6.0CA-7 is manufactured in IATF 16949-certified facilities and qualified to JEDEC reliability standards referenced in AEC-Q200. While not explicitly labeled "AEC-Q200 qualified", its process flow, testing, and change control align with automotive-grade expectations - Diodes' Q-suffix variants (e.g., SMF4L6.0CQ) carry formal AEC-Q200 certification.
What is the maximum allowable PCB trace length between SMF4L6.0CA-7 and protected IC?
To maintain sub-5ns response, keep trace length ≤5mm from TVS terminals to protected IC pins and ground plane. Longer traces add inductance that degrades clamping speed; use dedicated low-inductance ground vias adjacent to each terminal and avoid routing near noisy switching nodes.
