Product details
Overview
SMBJ6.0CA/1 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AA (SMBJ) package, designed for clamping voltage transients on signal or power lines. It features a 6.4 V minimum breakdown voltage (VBR), 6.0 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 58.3 A peak pulse current (IPPM), and 10.3 V maximum clamping voltage (VC) - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMBJ6.0CA/1 datasheet, SMBJ6.0CA/1 pinout, SMBJ6.0CA/1 application, or SMBJ6.0CA/1 equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C junction temperature rating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protection element, responding within picoseconds to transient overvoltages induced by inductive switching or ESD events. Its bi-directional symmetry ensures identical electrical characteristics in both polarities, with no polarity marking on the case - unlike uni-directional variants that feature a cathode band.
The SMBJ6.0CA/1 uses a glass-passivated silicon junction and is rated for repetitive 0.01% duty cycle surges. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation up to TJ = 150 °C when mounted per recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.4 V to 7.07 V at 10 mA test current - defines guaranteed conduction onset under surge conditions |
| VWM | 6.0 V - maximum continuous reverse voltage before leakage exceeds 800 µA |
| VC @ IPPM | 10.3 V at 58.3 A - clamped voltage seen by protected circuit during 10/1000 µs transient |
| PPPM | 600 W - peak surge power handling capability under standardized waveform |
| TJ max. | 150 °C - maximum allowable junction temperature for sustained reliability |
| MSL Level | Level 1 per J-STD-020 - no floor life limitation; safe for reflow up to 260 °C peak |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
Package: DO-214AA (SMBJ), surface-mount, bi-directional configuration with unmarked terminals - no cathode band or polarity indicator.

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed across differential or single-ended signal lines upstream of interface ICs. Use Value: Limits transient voltage to ≤10.3 V during 58.3 A surges, preserving integrity of 5 V or 3.3 V logic interfaces without adding series impedance. | Use Scenario: Shielding digital input modules in programmable logic controllers from field-wiring induced transients during relay switching or motor contactor operation. IC Role / Device Role / Timing Role: Parallel-connected TVS on 24 V DC input channels to absorb inductive kickback energy before it reaches optocoupler or microcontroller inputs.

IC Role / Device Role / Timing Role: Clamp device placed between +VOUT and GND to shunt transient energy away from PWM controller and output capacitor. Use Value: Fast response time and low clamping voltage prevent overvoltage damage to 6.0 V-rated reference ICs and error amplifiers. | Use Scenario: Protecting Ethernet PHY or DSL line drivers from ESD and induced surges on twisted-pair data lines in residential gateways and base stations. IC Role / Device Role / Timing Role: Bi-directional TVS installed differentially across pairs or common-mode across line-to-ground to meet IEC 61000-4-2/4-5 requirements. Use Value: Symmetrical VBR (6.4–7.07 V) and matched clamping ensure balanced protection without skewing differential signaling integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA-E3/52 | Same electrical specs; RoHS-compliant commercial grade (non-AEC-Q101) | Lacks automotive qualification; suitable for consumer/industrial but not automotive Tier-1 designs | Select when AEC-Q101 is not required and cost optimization is prioritized |
| SMBJ6.0CAHE3/52 | Identical specs and AEC-Q101 qualification; differs only in packaging suffix (HE3 denotes qualified grade) | No functional difference; same use cases and reliability validation | Preferred for new automotive designs requiring traceable qualified lots |
Compared with SMBJ6.0CA/1, SMBJ6.0CA-E3/52 offers identical clamping performance but omits automotive qualification evidence, while SMBJ6.0CAHE3/52 provides full AEC-Q101 documentation traceability - making SMBJ6.0CA/1 ideal for legacy automotive BOMs where /1 suffix denotes specific tape-and-reel configuration and lot-controlled sourcing.

FAQ
What is the clamping voltage of SMBJ6.0CA/1 at its rated peak pulse current?
The SMBJ6.0CA/1 has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 58.3 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components see no more than 10.3 V during worst-case surge events. The SMBJ6.0CA/1 maintains this clamping performance across its full operating temperature range.
Is SMBJ6.0CA/1 suitable for automotive applications?
Yes, SMBJ6.0CA/1 is AEC-Q101 qualified, meaning it has passed stress tests including temperature cycling, high-temperature reverse bias, and accelerated life testing required for automotive electronics. Its 150 °C maximum junction temperature and MSL Level 1 rating support reflow soldering in automotive module assembly. The SMBJ6.0CA/1 is commonly deployed in body control modules and sensor front-ends.
How does SMBJ6.0CA/1 differ from uni-directional SMBJ6.0A?
SMBJ6.0CA/1 is bi-directional with symmetrical breakdown in both polarities and no cathode marking, whereas SMBJ6.0A is uni-directional with a visible cathode band and conducts only in reverse bias. The SMBJ6.0CA/1's VBR range (6.4–7.07 V) applies equally in either direction, making it ideal for AC-coupled or floating signal lines where polarity is undefined - unlike SMBJ6.0A, which requires correct orientation during placement.
What is the thermal resistance of SMBJ6.0CA/1, and how does it affect layout design?
The SMBJ6.0CA/1 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per Vishay's recommended layout. To maintain TJ ≤ 150 °C under repetitive surges, designers must ensure adequate copper area and avoid excessive trace length - the SMBJ6.0CA/1 relies on thermal conduction through its leads into the PCB.
Does SMBJ6.0CA/1 require polarity-aware PCB footprint design?
No - SMBJ6.0CA/1 is a bi-directional device with no polarity marking; its DO-214AA package has identical terminals with no cathode band. The PCB footprint can be symmetric, simplifying layout and eliminating orientation errors during automated placement. This contrasts with uni-directional variants like SMBJ6.0A, which require strict anode/cathode alignment. The SMBJ6.0CA/1's symmetry is confirmed in Vishay's datasheet note stating "no marking on bi-directional types."
