Product details
Overview
SMBJ6.0CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features 6.4 V minimum breakdown voltage (VBR), 6.0 V maximum stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - deployed in sensor interface protection and industrial I/O circuits.
For engineers reviewing the SMBJ6.0CA-E3/5B datasheet, SMBJ6.0CA-E3/5B pinout, SMBJ6.0CA-E3/5B application, or SMBJ6.0CA-E3/5B equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), JEDEC-compliant SMB package dimensions, and AEC-Q101-qualified alternatives for automotive-grade design validation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR (6.4–7.07 V), VWM (6.0 V), and IPPM (58.3 A) ratings in either direction. Its glass-passivated junction ensures stable avalanche conduction and low incremental surge resistance under repetitive transient stress.
Designed for automated SMT placement, it meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), has matte tin-plated leads compliant with J-STD-002, and supports 0.01 % duty cycle operation with derating above TA = 25 °C per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA test current - defines reliable avalanche initiation threshold in both directions |
| VWM | 6.0 V - maximum continuous reverse voltage before significant leakage; ensures no false triggering during normal operation |
| IPPM | 58.3 A (10/1000 µs waveform) - peak surge current handling capacity before clamping voltage exceeds 10.3 V |
| VC @ IPPM | ≤10.3 V - clamped voltage level protecting downstream ICs from overvoltage damage |
| PPPM | 600 W - peak pulse power dissipation capability under standardized transient conditions |
| TJ max. | +150 °C - maximum junction temperature enabling operation in harsh industrial environments |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional device with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H), cathode band omitted per bidirectional configuration.

| MSL Level 1 moisture sensitivity | Eliminates bake-out requirement prior to reflow, reducing manufacturing cost and process complexity |
| Glass passivated junction | Ensures long-term stability of breakdown characteristics and low leakage (<1 µA @ 6.0 V) |
| RoHS-compliant, halogen-free option available | Supports environmental compliance for global industrial and automotive supply chains |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure/temperature sensors exposed to load dump and inductive switching noise in factory automation systems. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching ADC front-end. Use Value: Prevents sensor signal corruption and ADC latch-up by limiting voltage excursions to ≤10.3 V during 58.3 A surges. |
Use Scenario: Safeguarding LIN bus transceiver I/O pins against battery line transients and ESD events in door module electronics. IC Role / Device Role / Timing Role: Secondary-level TVS placed after primary fuse, providing fast-response overvoltage suppression aligned with ISO 16750-2 pulse requirements. Use Value: Maintains LIN communication integrity under 10/1000 µs surges up to 600 W without degrading signal rise time. |
| Consumer USB Port Protection | Telecom Power Supply Input |
|
Use Scenario: Clamping induced surges on USB 2.0 D+/D− lines caused by hot-plug events and nearby RF coupling in set-top boxes. IC Role / Device Role / Timing Role: Low-capacitance bidirectional suppressor mounted adjacent to USB connector to minimize trace inductance. Use Value: Limits differential-mode transients to <10.3 V while maintaining signal integrity due to inherent low junction capacitance (~500 pF at 0 V). |
Use Scenario: Front-end surge suppression on 12 V DC input rails of VoIP gateways subjected to lightning-induced surges per IEC 61000-4-5. IC Role / Device Role / Timing Role: Primary transient clamp in parallel with bulk capacitor, absorbing energy before upstream regulator stages. Use Value: Handles repetitive 600 W pulses with <0.01 % duty cycle, preventing thermal runaway in continuous-duty telecom applications. |
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-M3/5B | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package | No difference in circuit performance; selected where halogen-free material compliance is mandated | Choose when environmental compliance requires halogen-free construction without altering layout or BOM |
| SMBJ6.0CAHE3_B/I | AEC-Q101 qualified, same VBR/VWM/VC, but rated for automotive temperature range and qualification testing | Required for under-hood or body electronics where automotive reliability standards apply | Select for automotive designs needing formal AEC-Q101 validation; not necessary for commercial/industrial use |
Compared with SMBJ6.0CA-E3/5B, the M3/5B offers halogen-free materials without electrical trade-offs, while the HE3_B/I adds AEC-Q101 qualification for automotive deployment - neither is pin-compatible drop-in replacements unless explicitly specified in design requirements.

FAQ
What is the breakdown voltage tolerance for SMBJ6.0CA-E3/5B?
The SMBJ6.0CA-E3/5B has a guaranteed breakdown voltage range of 6.4 V to 7.07 V at 10 mA test current, measured in both directions due to its bidirectional construction. This ±5.5 % tolerance ensures consistent clamping behavior across production lots and operating temperatures, supporting predictable system-level surge immunity design without margin over-engineering.
Does SMBJ6.0CA-E3/5B require a heatsink for 600 W pulse handling?
No, SMBJ6.0CA-E3/5B does not require an external heatsink for single 10/1000 µs pulses, as its 600 W rating is defined under standard PCB mounting conditions (0.2" × 0.2" copper pads per terminal). However, repetitive surges at 0.01 % duty cycle demand strict adherence to thermal derating curves in Figure 2 of the datasheet to avoid junction temperature exceedance beyond +150 °C.
How does SMBJ6.0CA-E3/5B differ from unidirectional SMBJ6.0A?
SMBJ6.0CA-E3/5B is bidirectional with symmetrical VBR, VWM, and clamping in both polarities, while SMBJ6.0A is unidirectional and conducts only in reverse bias. The CA version eliminates need for polarity-aware layout and supports AC-coupled or floating signal lines - critical for differential buses like RS-485 or LIN where voltage reversals occur naturally.
Is SMBJ6.0CA-E3/5B suitable for IEC 61000-4-5 compliance testing?
Yes, SMBJ6.0CA-E3/5B is routinely used to meet IEC 61000-4-5 Level 4 (4 kV line-to-earth, 2 kV line-to-line) when applied with appropriate series impedance and PCB layout. Its 600 W peak pulse rating, ≤10.3 V clamping, and fast response time enable effective energy diversion - confirmed by Vishay's application note AN1002 on TVS-based surge protection architectures.
What is the maximum leakage current of SMBJ6.0CA-E3/5B at rated VWM?
The SMBJ6.0CA-E3/5B exhibits ≤1 µA maximum reverse leakage current at its rated 6.0 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage prevents signal distortion or power drain in high-impedance sensor or communication circuits, and remains stable across the full -55 °C to +150 °C operating junction temperature range.
