Product details
Overview
SMBJ6.0CA-E3/52 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 DC power rail surge suppression.
For engineers reviewing the SMBJ6.0CA-E3/52 datasheet, SMBJ6.0CA-E3/52 pinout, SMBJ6.0CA-E3/52 application, or SMBJ6.0CA-E3/52 equivalent, this page delivers verified electrical parameters, 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) specifications in either direction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for protecting MOSFET gates and microcontroller I/O against ESD and inductive switching spikes.
Rated for -55 °C to +150 °C junction temperature, it meets MSL Level 1 per J-STD-020 (260 °C peak reflow), supports automated SMT placement, and achieves UL 94 V-0 flammability compliance via its molding compound. The matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.

|---|---|
|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, absorbing transients while maintaining signal integrity during normal operation. Use Value: Prevents latch-up or gate oxide damage in transceiver ICs by limiting voltage excursion to ≤10.3 V during 58.3 A surge events. |
Use Scenario: Safeguarding 24 V digital input modules in programmable logic controllers against field-wiring induced surges and contact bounce. IC Role / Device Role / Timing Role: Standoff voltage (6.0 V) blocks normal 24 V DC bias while clamping fast-rising transients to safe levels. Use Value: Eliminates need for external series impedance or RC filtering - reduces BOM count and PCB area versus discrete Zener+capacitor solutions. |
| Consumer Power Adapter Output Protection | Telecom Line Card Surge Suppression |
|
Use Scenario: Secondary-side overvoltage suppression in USB-C PD adapters and wall chargers exposed to output short-circuit recovery spikes.

IC Role / Device Role / Timing Role: Bidirectional clamping element placed differential-to-ground on twisted-pair lines, handling ±600 W transient energy. Use Value: Meets ITU-T K.21 basic protection requirements for residential telecom equipment without requiring gas discharge tube coordination. |
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-M3/52 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package | No difference in circuit performance; selected where halogen-free materials are mandated (e.g., EU medical devices) | Direct material substitution when halogen-free compliance is required; same layout and thermal profile |
| SMBJ6.0CAHE3_B/I | AEC-Q101 qualified, RoHS-compliant, supplied in 13" tape-and-reel (3200 pcs); identical VBR, VWM, and PPPM | Validated for automotive under-hood use (e.g., body control modules) with extended temperature cycling and HAST reliability data | Required for automotive OEM designs needing certified reliability; no electrical redesign needed |
Compared with SMBJ6.0CA-E3/52, the M3 variant offers halogen-free construction for stricter environmental compliance, while the HE3 variant adds AEC-Q101 qualification for automotive deployment - both retain identical clamping performance and SMB footprint, enabling drop-in replacement where material or reliability certification drives selection.

FAQ
What is the breakdown voltage range of SMBJ6.0CA-E3/52?
The SMBJ6.0CA-E3/52 has a guaranteed breakdown voltage (VBR) range of 6.4 V to 7.07 V at 10 mA test current, measured bidirectionally. This ensures consistent clamping onset regardless of transient polarity and aligns with its 6.0 V stand-off voltage (VWM) for reliable blocking during normal operation. The specification is validated per ANSI/IEEE C62.35 standards.
Is SMBJ6.0CA-E3/52 suitable for automotive applications?
SMBJ6.0CA-E3/52 itself is commercial-grade; however, the AEC-Q101-qualified variant SMBJ6.0CAHE3_B/I is available for automotive use. The SMBJ6.0CA-E3/52 shares identical electrical characteristics and SMB package, but lacks the extended reliability testing required for under-hood deployment. For non-critical cabin applications with ambient temperatures below 125 °C, SMBJ6.0CA-E3/52 may be used with customer validation.
What is the maximum clamping voltage of SMBJ6.0CA-E3/52 at rated surge current?
The SMBJ6.0CA-E3/52 clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This clamping voltage is measured across the device terminals during transient conduction and defines the upper voltage limit imposed on protected circuits - critical for ensuring downstream ICs remain within absolute maximum ratings.
Does SMBJ6.0CA-E3/52 require a heatsink for 600 W pulse handling?
No external heatsink is required for single-event 600 W pulse handling, as the SMBJ6.0CA-E3/52 relies on thermal mass and PCB copper pads (0.2" × 0.2") for transient energy dissipation. Its RθJA of 100 °C/W applies to steady-state conditions; during short-duration pulses (<1 ms), junction temperature rise is dominated by thermal capacitance, not steady-state resistance - making heatsinks unnecessary for typical surge events.
How does the bidirectional nature of SMBJ6.0CA-E3/52 affect PCB layout?
The SMBJ6.0CA-E3/52 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout and automated assembly - no silkscreen polarity indicators or footprint asymmetry are needed. Layout must still follow recommended 5.0 mm × 5.0 mm copper pad dimensions per terminal to maintain specified thermal and surge performance.
