Product details
Overview
SMF4L130CA-7 from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in DO-219AA package, rated for 400W peak pulse power (10/1000µs), 130V working peak reverse voltage (VRWM), and clamping voltage (VC) of 209V at 1A surge current. It delivers ±30kV ESD protection per IEC61000-4-2 and is used for overvoltage protection on automotive battery contacts and industrial power rails.
For engineers reviewing the SMF4L130CA-7 datasheet, SMF4L130CA-7 pinout, SMF4L130CA-7 application, or SMF4L130CA-7 equivalent, key selection criteria include clamping voltage margin relative to system rail, bidirectional surge handling capability, JEDEC-qualified reliability for high-temp environments, and DO-219AA footprint compatibility with space-constrained PCB layouts.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust protection against positive and negative transients without polarity dependency. Its breakdown voltage range (144V–159V at 1mA) ensures stable triggering above 130V VRWM while maintaining low leakage (<0.5µA at 130V).
The device achieves sub-5ns response time from 0V to VBR min, with thermal resistance RθJA of 96°C/W and junction-to-case RθJC of 18°C/W - critical for sustained surge dissipation in automotive under-hood applications operating up to +175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W (10/1000µs waveform): enables single-event suppression of high-energy load-dump transients in 12V/24V automotive systems |
| Working Peak Reverse Voltage (VRWM) | 130V: sets maximum continuous DC or AC RMS voltage before clamping initiates; matches 120VAC mains or 100V+ DC bus rails |
| Clamping Voltage (VC) | 209V at 1A: defines upper voltage limit seen by protected circuit during surge; provides 60% margin above VRWM |
| ESD Rating | ±30kV contact & air (IEC61000-4-2): qualifies for direct human-interface port protection without external shielding |
| Junction Temperature Range | −55°C to +175°C: supports operation in engine control units, battery management systems, and industrial motor drives |
| Package | DO-219AA: 2.8mm × 1.9mm surface-mount outline with cathode-less marking for bi-directional symmetry and automated optical inspection compatibility |
Pinout & Package
DO-219AA is a two-terminal, symmetrical SMD package with no polarity marking for bi-directional devices. Terminals are matte tin-finished copper alloy leads, solderable per MIL-STD-202 Method 208, and mounted on FR-4 PCB with 2 oz. Cu pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Bi-directional conduction allows identical clamping behavior for positive and negative surges; no orientation required during placement |
| Case / Body | Thermal interface | Molded plastic body with UL 94V-0 rating provides insulation and mechanical stability; thermal path to PCB via solder joints |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-qualified high-reliability construction | Qualified to AEC-Q200 stress test requirements for automotive-grade passive components, including temperature cycling and humidity testing |
| Halogen- and antimony-free "Green" compound | Meets <900ppm Br, <900ppm Cl, <1000ppm Sb thresholds - compliant with global environmental regulations and RoHS 3 (2015/863/EU) |
| Fast transient response | Response time <5.0ns (bi-directional) ensures clamping activation before sensitive downstream ICs experience overvoltage stress |
| Low leakage current | IR ≤ 0.5µA at VRWM = 130V minimizes standby power loss in always-on battery-powered systems |
Applications
| Automotive Battery Protection | Industrial Power Supply Input |
|---|---|
Use Scenario: Protecting battery management system (BMS) inputs against load dump and jump-start transients in 24V commercial vehicles. IC Role / Device Role / Timing Role: Primary clamping element placed directly at connector entry point to shunt >100A surge currents away from monitoring ICs and microcontrollers. Use Value: 209V clamping voltage prevents damage to 16-bit ADCs and isolated CAN transceivers rated for 220V absolute max, extending field reliability beyond ISO 7637-2 Pulse 5a requirements. | Use Scenario: Safeguarding AC/DC converter primary-side rectifier outputs against lightning-induced surges on factory floor power distribution lines. IC Role / Device Role / Timing Role: Secondary-level TVS deployed after bulk filter capacitors to absorb residual ring wave energy not suppressed by MOVs. Use Value: 400W peak power rating handles 6kV/3kA combination wave surges per IEC 61000-4-5 Level 4 without degradation, reducing need for redundant protection stages. |
| Smart Meter Communication Ports | Medical Equipment Mains Interface |
Use Scenario: Shielding RS-485 and PLC communication lines in utility smart meters exposed to induced surges from nearby switching events. IC Role / Device Role / Timing Role: Bi-directional line protector placed differential-mode across signal pairs to clamp common-mode transients coupled onto data lines. Use Value: Symmetrical clamping ensures equal protection for TX+/TX− and RX+/RX−, preserving signal integrity during ±30kV ESD events without skew or distortion. | Use Scenario: Providing secondary overvoltage protection on isolated AC input stage of Class II medical power supplies (e.g., patient monitors). IC Role / Device Role / Timing Role: Reinforcement layer behind primary Y-capacitor and fuse, limiting let-through voltage to <250V during fast-rising transients. Use Value: 175°C max junction temperature enables uninterrupted operation inside sealed enclosures with limited airflow, meeting IEC 60601-1 creepage/clearance safety margins. |
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 |
|---|---|---|---|
| SMAJ130CA-TP | DO-214AC (SMA) package; 400W rating; VRWM = 130V; VC = 219V at 1A | Larger footprint (4.5mm × 2.7mm) limits use in ultra-dense layouts; higher RθJA (120°C/W) reduces thermal headroom | Select when legacy SMA land patterns exist or manual rework is preferred due to larger solder joint area |
| 1.5KE130CA | DO-201AD (axial) package; 1500W rating; VRWM = 130V; VC = 219V at 12.5A | Through-hole mounting incompatible with full SMT assembly; higher clamping voltage at lower currents increases risk to downstream logic | Choose only for prototyping or low-volume repair where board real estate and assembly process allow axial components |
Compared with SMAJ130CA-TP and 1.5KE130CA, SMF4L130CA-7 offers superior board-space efficiency (DO-219AA is 65% smaller than SMA), lower thermal resistance (96°C/W vs. 120°C/W), and tighter clamping consistency across production lots - making it optimal for high-volume automotive and industrial SMT production.

FAQ
What is the polarity configuration of SMF4L130CA-7?
SMF4L130CA-7 is a bi-directional TVS diode with no cathode band marking, indicating symmetrical conduction in both directions. This eliminates orientation concerns during automated placement and ensures identical clamping behavior for positive and negative transients on the same line.
Does SMF4L130CA-7 meet automotive qualification standards?
Yes - SMF4L130CA-7 is qualified to AEC-Q200 for passive components and manufactured in IATF 16949-certified facilities. It undergoes temperature cycling, humidity testing, and surge endurance validation per automotive stress requirements, supporting use in engine control, body electronics, and battery systems.
How does the DO-219AA package affect thermal performance?
The DO-219AA package delivers RθJA = 96°C/W and RθJC = 18°C/W when mounted on a 1" × 1" FR-4 board with 2 oz. copper. Its compact size and low-profile construction enable efficient heat transfer to the PCB plane, supporting reliable 400W pulse dissipation in confined spaces like automotive ECUs and power modules.
Can SMF4L130CA-7 replace older SMAJ or SMBJ series devices?
It can replace SMAJ130CA or SMBJ130CA in new designs where board space is constrained and thermal performance must be improved. However, due to its smaller DO-219AA footprint and different pad layout, direct drop-in replacement requires PCB revision - unlike SMA/SMB packages which share compatible land patterns.
