Product details
Overview
SMAJ6.0CA-13-F from Diodes Incorporated is a bidirectional 400W transient voltage suppressor (TVS) diode in SMA package, designed for clamping ESD and surge transients on data lines and power rails. It features a 6.0V reverse standoff voltage (VRWM), 10.3V max clamping voltage at 38.8A peak pulse current (IPP), and fast response time for IEC 61000-4-2/4-5 compliance.
For engineers reviewing the SMAJ6.0CA-13-F datasheet, SMAJ6.0CA-13-F pinout, SMAJ6.0CA-13-F application, or SMAJ6.0CA-13-F equivalent, this device is selected for robust overvoltage protection in automotive infotainment interfaces, industrial sensor signal conditioning, and USB 2.0 port ESD hardening where low clamping voltage and unidirectional/bidirectional flexibility matter.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified between 6.67V and 7.37V at 10mA test current. Its clamping performance is validated under standardized 10/1000μs waveform conditions, delivering ≤10.3V clamping at 38.8A IPP while maintaining <800μA reverse leakage at VRWM.
Thermally rated for -55°C to +150°C operating junction temperature, it sustains 400W non-repetitive peak pulse power with derating above +25°C ambient, and supports steady-state dissipation up to 1.0W at lead temperature of +75°C per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - withstands high-energy surges without failure in IEC 61000-4-5 Level 4 testing. |
| Reverse Standoff Voltage | 6.0V - maximum continuous working voltage before clamping initiates; matches 5V logic rail systems. |
| Clamping Voltage | 10.3V @ 38.8A - limits transient voltage to safe levels for downstream 12V-tolerant receivers. |
| Breakdown Voltage | 6.67–7.37V @ 10mA - ensures reliable turn-on margin above VRWM for stable protection threshold. |
| Package | SMA - surface-mount plastic case (UL 94V-0), 0.064g weight, compatible with standard reflow profiles. |
| Operating Temperature | -55°C to +150°C - qualified for under-hood automotive and industrial environments. |
Pinout & Package
Two-terminal SMA package with cathode band omitted (bidirectional configuration). Terminals are matte tin-plated for solderability per MIL-STD-202, Method 208; polarity indicator not present due to symmetrical conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts during either polarity overvoltage event. |
| Case (SMA body) | Thermal and mechanical interface | Molded plastic housing provides UL 94V-0 flammability rating and 1.27–1.63mm height tolerance. |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power | Enables single-device protection against 1kV/500A IEC 61000-4-5 combination wave surges. |
| Glass passivated die | Improves reliability and moisture resistance vs. epoxy-passivated alternatives in humid environments. |
| Bidirectional operation | Eliminates need for polarity-aware layout; protects AC-coupled or differential signal lines (e.g., RS-485, CAN). |
| RoHS 3 & "Green" compliant | Contains <900ppm Br, <900ppm Cl, <1000ppm Sb - meets automotive and industrial environmental mandates. |
Applications
| Automotive Infotainment Interface | Industrial RS-485 Transceiver Protection |
|---|---|
Use Scenario: Protecting HDMI, USB, or LVDS lines in head unit displays from ESD events during assembly or end-user handling. IC Role / Device Role: Bidirectional TVS placed at connector entry point to shunt transients before reaching PHY ICs. Use Value: 10.3V clamping ensures no damage to 12V-tolerant receiver inputs while meeting ISO 10605 ±15kV air discharge requirements. | Use Scenario: Safeguarding half-duplex RS-485 transceivers in factory automation PLCs exposed to motor switching noise. IC Role / Device Role: Differential-line TVS across A/B bus pins to clamp common-mode surges induced by nearby 480VAC drives. Use Value: Symmetrical 6.0V standoff allows direct placement without polarity concern; 400W rating handles repetitive 4kV surge pulses per IEC 61000-4-4. |
| USB 2.0 Port ESD Hardening | DC Power Rail Surge Suppression |
Use Scenario: Adding secondary ESD protection on Type-A USB ports in medical diagnostic equipment where internal LDOs limit fault energy. IC Role / Device Role: Secondary TVS after primary polymer PTC, clamping fast-rising ±8kV contact ESD per IEC 61000-4-2. Use Value: Sub-100ns response time and 10.3V clamping prevent latch-up in USB PHYs rated for 3.3V/5V operation. | Use Scenario: Protecting 12V auxiliary power inputs in telecom base station modules from lightning-induced surges on outdoor cabling. IC Role / Device Role: Parallel-connected TVS on input rail to divert >1kA surge currents away from DC-DC controllers and MOSFETs. Use Value: 38.8A IPP capability enables coordination with upstream fuses or resettable PPTCs for selective fault clearing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-13-F | Unidirectional version; includes cathode band marking and forward voltage drop (~3.5V @ 35A). | Requires correct polarity orientation; unsuitable for AC or differential lines. | Select only when protecting DC rails with known polarity and no reverse-voltage risk. |
| SMBJ6.0CA | Same electrical specs but SMB package (higher thermal mass, 600W rating, larger footprint). | Offers better surge endurance but occupies ~2.5× PCB area; requires different pad layout. | Choose when system-level surge tests exceed 400W or board space permits larger package. |
Compared with SMAJ6.0A-13-F and SMBJ6.0CA, SMAJ6.0CA-13-F uniquely balances bidirectional symmetry, compact SMA footprint, and verified 400W surge capacity-making it optimal for space-constrained, polarity-agnostic protection in automotive and industrial serial interfaces.

FAQ
What is the difference between SMAJ6.0CA-13-F and SMAJ6.0A-13-F?
SMAJ6.0CA-13-F is bidirectional with symmetrical clamping for AC or differential signals, while SMAJ6.0A-13-F is unidirectional and includes a cathode band for polarity-specific placement. The "C" suffix explicitly denotes bidirectional construction per Diodes' datasheet DS19005 Rev. 19-2, Table on page 3.
Does SMAJ6.0CA-13-F meet AEC-Q200 requirements?
No-SMAJ6.0CA-13-F is a standard-grade part. Diodes offers an automotive-qualified variant under separate datasheet SMAJ6.0(C)AQ with AEC-Q200 qualification, PPAP capability, and IATF 16949 manufacturing. This part lacks those certifications and is intended for industrial/commercial use only.
What is the thermal resistance junction-to-lead (RθJL) for this device?
RθJL is not published in DS19005 Rev. 19-2. However, steady-state power dissipation is rated at 1.0W at TL = +75°C, implying RθJL ≈ 75°C/W based on TJ(max) = +150°C. For precise thermal modeling, refer to Diodes' thermal simulation tools or request characterization data directly from their applications engineering team.
Can SMAJ6.0CA-13-F be used in parallel for higher surge current handling?
Parallel connection is not recommended without current-sharing resistors or matched VBR tolerances. The SMAJ6.0CA-13-F has ±7.5% VBR variation (6.67–7.37V); mismatched units may cause uneven current division and premature failure. For >38.8A IPP, select a higher-rated single device like SMBJ6.0CA instead.
