Product details
Overview
SMBJ6.0CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 6.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤10.3 V at 58.3 A peak surge current - used in sensor interface protection and DC power rail surge suppression.
For engineers reviewing the SMBJ6.0CA-M3/5B datasheet, SMBJ6.0CA-M3/5B pinout, SMBJ6.0CA-M3/5B application, or SMBJ6.0CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, low clamping voltage under 600 W surge, MSL Level 1 reflow compatibility, halogen-free RoHS compliance, and suitability for automotive-grade designs when ordered with HM3 suffix.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical avalanche breakdown in both directions, enabling robust protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response (<1 ns), while the low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The SMBJ6.0CA-M3/5B is rated for -55 °C to +150 °C operating junction temperature, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, requiring minimal PCB copper area for thermal management. It meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - maximum continuous reverse working voltage before conduction begins; sets upper limit for normal circuit operation. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - guaranteed avalanche onset range; defines minimum clamping threshold under transient stress. |
| VC @ IPPM | ≤10.3 V at 58.3 A - clamped voltage during 600 W 10/1000 µs surge; determines protected circuit's maximum overvoltage exposure. |
| PPPM | 600 W - peak pulse power handling per single transient; enables protection against IEC 61000-4-5 Level 4 surges. |
| IPPM | 58.3 A - peak surge current supported at VC; defines minimum trace width and fuse coordination requirements. |
| TJ max. | +150 °C - maximum junction temperature; allows operation in under-hood automotive or industrial environments. |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 5.21 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place. |
Pinout & Package

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-E3/5B | Same electrical specs, but RoHS-compliant with standard tin plating (not halogen-free); MSL Level 1, 260 °C. | No halogen-free certification; suitable for commercial-grade non-automotive applications where material compliance is less stringent. | Select SMBJ6.0CA-E3/5B for cost-sensitive consumer electronics where halogen-free requirement is not mandated. |
| SMAJ6.0CA-M3 | Lower peak pulse power (400 W vs. 600 W); same VWM, VBR, and VC; smaller SMA (DO-214AC) package (4.5 × 2.7 mm). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); insufficient for automotive load dump or industrial 4 kV surge testing. | Choose SMAJ6.0CA-M3 only when board space is critical and surge threat level is constrained to ≤400 W events. |
Compared with SMBJ6.0CA-E3/5B, the SMBJ6.0CA-M3/5B adds halogen-free compliance without sacrificing surge rating or thermal performance; versus SMAJ6.0CA-M3, it delivers 50 % higher pulse power in a slightly larger but more robust SMB package - critical for automotive and industrial deployments.

FAQ
What does the "CA" suffix mean in SMBJ6.0CA-M3/5B?
The "CA" suffix denotes a bidirectional configuration - meaning the SMBJ6.0CA-M3/5B provides symmetrical clamping for both positive and negative voltage transients. Unlike unidirectional variants (e.g., SMBJ6.0A), it has no cathode marking and functions identically regardless of terminal orientation, making it ideal for AC-coupled or differential signal lines where polarity is undefined or reversible.
Is SMBJ6.0CA-M3/5B suitable for automotive applications?
Yes - the SMBJ6.0CA-M3/5B itself is halogen-free and RoHS-compliant, and when ordered with HM3 suffix (e.g., SMBJ6.0CAHM3_B/I), it is AEC-Q101 qualified. Even in standard M3 form, its -55 °C to +150 °C operating range, 600 W surge rating, and UL 497B recognition make SMBJ6.0CA-M3/5B appropriate for non-safety-critical automotive subsystems such as infotainment power rails or sensor interfaces.
What is the clamping voltage of SMBJ6.0CA-M3/5B under surge conditions?
The SMBJ6.0CA-M3/5B clamps to a maximum of 10.3 V when subjected to its rated 58.3 A peak pulse current (10/1000 µs waveform). This clamping voltage is measured at the device terminals and represents the highest voltage seen by downstream circuitry during a full 600 W transient event - a key parameter for ensuring protected ICs remain within absolute maximum ratings.
How does SMBJ6.0CA-M3/5B differ from SMBJ6.0A-M3/5B?
The SMBJ6.0CA-M3/5B is bidirectional, while SMBJ6.0A-M3/5B is unidirectional with a marked cathode band. Electrically, SMBJ6.0A-M3/5B conducts only during positive surges relative to its cathode, whereas SMBJ6.0CA-M3/5B clamps equally for both polarities. The unidirectional version also supports 100 A IFSM (forward surge), which does not apply to the CA variant - a critical distinction for DC power line protection where forward conduction may occur.
What PCB pad layout is recommended for SMBJ6.0CA-M3/5B?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad for each terminal of SMBJ6.0CA-M3/5B to achieve rated thermal performance and 600 W pulse power dissipation. The SMB (DO-214AA) package requires symmetric, thermally balanced pads with adequate solder mask clearance; refer to Figure 5 in document 88392 for exact dimensions and stencil recommendations to ensure reliable reflow and mechanical strength.
