Product details
Overview
SMBJ6.0CA-13-F from Diodes Incorporated is a bi-directional transient voltage suppressor (TVS) diode in SMB package, designed for robust overvoltage protection in DC power lines and signal interfaces. It features 600W peak pulse power dissipation, 6.0V reverse standoff voltage (VRWM), 10.3V maximum clamping voltage at 58.3A peak pulse current, and operates across –55°C to +150°C junction temperature range - deployed in industrial power supplies and automotive body control modules.
For engineers reviewing the SMBJ6.0CA-13-F datasheet, SMBJ6.0CA-13-F pinout, SMBJ6.0CA-13-F application, or SMBJ6.0CA-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC rails, unidirectional vs. bi-directional polarity requirements for AC-coupled or bidirectional data lines, and thermal derating above +25°C ambient.
Technical Context
This bi-directional TVS diode functions as a voltage-clamped shunt protector: under normal operation it presents <10 µA leakage at VRWM = 6.0V; during transients exceeding VBR (min 6.67V), it avalanches to clamp voltage ≤10.3V at IPP = 58.3A (8.3ms half-sine waveform). Its glass-passivated die ensures stable breakdown characteristics and low capacitance (<100 pF at 1 MHz).
Designed for surface-mount integration on PCBs with limited board space, it leverages SMB package thermal mass to sustain 5.0W steady-state power at TL = +75°C and supports automated reflow assembly per J-STD-020 Level 1 moisture sensitivity. Lead-free matte tin plating ensures MIL-STD-202-compliant solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 8.3ms surge events without failure in IEC 61000-4-5 Level 4 compliance designs. |
| Reverse Standoff Voltage | 6.0V - defines maximum continuous DC or RMS AC voltage before significant leakage; sets minimum operating rail compatibility. |
| Breakdown Voltage | 6.67–7.67V @ 10mA - ensures reliable avalanche initiation just above system nominal voltage, minimizing false triggering. |
| Clamping Voltage | 10.3V @ 58.3A - limits transient voltage seen by downstream ICs; critical for protecting 5V/6V logic and microcontrollers. |
| Junction Temperature Range | –55°C to +150°C - enables deployment in under-hood automotive, industrial motor drives, and outdoor power equipment. |
| Package | SMB - standardized surface-mount outline (5.59mm × 3.94mm × 2.21mm) with cathode-band omission confirming bi-directionality. |
Pinout & Package
SMB package: molded plastic case (UL 94V-0), 2-terminal device with no polarity marking (bi-directional configuration). Terminals are lead-free matte tin plated, compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Bi-directional conduction: conducts equally in both directions when voltage exceeds ±VBR - eliminates orientation concerns during placement. |
| Cathode Band (absent) | Polarity indicator | Missing band confirms bi-directional construction; no anode/cathode assignment required in schematic or layout. |
Key Features
| Feature | Design Value |
|---|---|
| 600W peak pulse rating | Enables compliance with IEC 61000-4-5 (1.2/50µs + 8/20µs combo wave) up to Level 4 (4kV/2kA) in properly routed layouts. |
| Glass-passivated die | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime - critical for safety-critical power rails. |
| Bi-directional architecture | Protects AC-coupled interfaces (e.g., RS-485, CAN FD, audio lines) without requiring external series coupling capacitors or polarity-aware routing. |
| RoHS & Halogen-Free | Meets EU RoHS 2 (2011/65/EU) and green standards (<900ppm Br, <900ppm Cl, <1000ppm Sb) - supports global environmental compliance programs. |
Applications
| Industrial Power Input Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 12V battery-fed DC input stage exposed to load dump (ISO 7637-2 Pulse 5a) and jump-start surges. IC Role / Device Role / Timing Role: Primary shunt clamping element placed directly at connector entry point before DC-DC converter input. Use Value: Clamps transients to ≤10.3V, preventing damage to 16V-rated input MOSFETs and enabling use of lower-voltage, cost-optimized downstream regulators. |
Use Scenario: LIN bus physical layer interface subjected to ESD (IEC 61000-4-2 ±8kV contact) and coupled noise from adjacent solenoid drivers. IC Role / Device Role / Timing Role: Localized ESD suppression at LIN transceiver pins, placed within 5mm of connector. Use Value: Sub-100pF capacitance avoids signal integrity degradation on 20.5kbaud LIN signals while meeting automotive ESD immunity targets. |
| RS-485 Data Line Protection | USB Type-C VBUS Overvoltage Clamp |
Use Scenario: Half-duplex RS-485 transceivers in factory automation networks subject to induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: Bi-directional clamping between A/B differential pair and ground, symmetrically placed on both lines. Use Value: Maintains common-mode transient immunity without distorting differential signaling due to matched clamping thresholds on both polarities. |
Use Scenario: USB Type-C receptacle where VBUS may be misconnected to legacy 20V PD sources or experience hot-plug overshoot. IC Role / Device Role / Timing Role: Secondary overvoltage clamp downstream of primary eFuse, limiting VBUS to safe levels for 5V/9V sink ICs. Use Value: Fast response (<1ps) and low clamping voltage prevent latch-up in USB PD controllers while surviving repeated 20V/100ns spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0C-13-F (Bourns) | Identical VRWM (6.0V), slightly higher VC = 10.5V @ 58A; same SMB package and RoHS profile. | Validated in Bourns' AEC-Q200 qualified automotive reference designs; tighter VBR tolerance (±5% vs. Diodes' ±7.5%). | Select when AEC-Q200 qualification is mandatory and clamping margin allows 0.2V higher VC. |
| P6SMB6.0CA (Littelfuse) | Same electrical specs (VRWM = 6.0V, VC = 10.3V @ 58.3A); identical SMB footprint but different date-code marking convention. | Extensive field history in telecom power systems; supported by Littelfuse's SPICE models and transient simulation libraries. | Prefer when design reuse from existing Littelfuse-based platforms or SPICE validation is required. |
Compared with SMBJ6.0CA-13-F, Bourns' SMBJ6.0C-13-F offers tighter VBR control for precision rail clamping, while Littelfuse's P6SMB6.0CA provides broader simulation tool support - both retain identical thermal and mechanical integration behavior in SMB-layout constrained designs.

FAQ
What is the difference between SMBJ6.0CA-13-F and SMBJ6.0A-13-F?
The "C" suffix denotes bi-directional construction, meaning the device clamps voltage symmetrically in both polarities - ideal for AC lines or differential buses. In contrast, SMBJ6.0A-13-F is unidirectional, with a cathode band and clamping only in reverse bias; it requires correct orientation and is used on DC rails where polarity is fixed.
Can SMBJ6.0CA-13-F protect against ISO 7637-2 Load Dump pulses?
No - ISO 7637-2 Pulse 5a (load dump) reaches up to 60V for 400ms and exceeds the 10.3V clamping capability. SMBJ6.0CA-13-F is rated for shorter transients (8.3ms half-sine); load dump requires higher-voltage TVS like SMBJ33CA or dedicated load dump suppressors with energy-handling >10J.
Is SMBJ6.0CA-13-F suitable for protecting USB 2.0 data lines?
No - its clamping voltage (10.3V) and capacitance (>100pF at low bias) are too high for USB 2.0 signal integrity. For D+/D− lines, use low-capacitance TVS arrays such as D3V3F4U-7 or SP1001-01WTG with <0.8pF capacitance and 3.3V clamping.
Does SMBJ6.0CA-13-F require a heatsink for 5.0W continuous dissipation?
No - the 5.0W rating applies only at TL = +75°C (lead temperature), not ambient. At +25°C ambient, steady-state dissipation is limited to ~1.2W without heatsinking; sustained power handling requires PCB copper area (≥1 sq-in thermal pad) or forced airflow per Figure 6 derating curve.
