Product details
Overview
SMBG6.0CA-M3/5B from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for clamping voltage transients on signal and power lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, 600 W peak pulse power (10/1000 μs), <10.3 V clamping voltage (VC) at rated surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG6.0CA-M3/5B datasheet, SMBG6.0CA-M3/5B pinout, SMBG6.0CA-M3/5B application, or SMBG6.0CA-M3/5B equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VBR ≈ 1.48), MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and suitability for I/O line protection in harsh environments where ESD and load-dump immunity are critical.
Technical Context
This device operates as a voltage-clamped shunt protector with symmetrical avalanche behavior in both polarities, enabling robust suppression of bipolar transients without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast energy diversion during sub-microsecond surges.
The SMBG6.0CA-M3/5B is rated for repetitive 10/1000 μs waveform pulses at 0.01% duty cycle and derates linearly above 25 °C ambient, with maximum junction temperature of +150 °C and thermal resistance RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads. It meets UL 497B recognition and complies with ANSI/IEEE C62.35 surge standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Ensures reliable turn-on within tight tolerance band for predictable clamping onset |
| VC @ IPPM | ≤10.3 V - Clamping voltage under full 600 W surge, limiting downstream IC stress to safe levels |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform, sufficient for ISO 7637-2 Pulse 1/2/5a |

Applications
| Automotive CAN Bus Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines in vehicle ECUs against battery transients, load dump, and ESD during assembly or service. IC Role / Device Role / Timing Role: Shunt-type transient suppressor placed directly at connector entry point, clamping surges before they reach CAN transceiver IC. Use Value: Prevents latch-up or permanent damage to CAN transceivers (e.g., TCAN1042, SN65HVD230) by limiting line voltage to ≤10.3 V during 5a pulses up to 600 W. | Use Scenario: Safeguarding long-haul RS-485 data links in factory automation systems exposed to motor switching noise and lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS mounted across differential pair (A/B) near PHY interface to absorb common-mode and differential-mode transients. Use Value: Maintains signal integrity by clamping transients within 1 ns response time, preserving data rates up to 20 Mbps without bit errors or retransmission overhead. |
| Consumer USB Port ESD Protection | Power Supply Input Surge Suppression |
Use Scenario: Adding secondary-level ESD protection on USB 2.0 D+ and D− lines in portable devices where internal SoC ESD structures are insufficient. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF typical) bidirectional clamp placed after connector but before USB transceiver PHY. Use Value: Absorbs ±15 kV contact discharge (IEC 61000-4-2) without signal distortion, meeting USB-IF compliance while adding <0.5 mm² board area. | Use Scenario: Protecting 5 V or 12 V DC input rails in embedded controllers from inductive kickback and AC line coupling in industrial power supplies. IC Role / Device Role / Timing Role: Primary shunt protector across input rail and ground, sized to handle repetitive 100 A surges per ISO 16750-2. Use Value: Limits rail overshoot to ≤10.3 V during 100 A transients, preventing brownout resets or LDO dropout in downstream PMICs and microcontrollers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0CA | Same VWM (6.0 V), identical VBR range, but lower PPPM = 600 W only at 10/1000 μs with reduced IPPM (58.3 A vs. SMBG6.0CA-M3/5B's 58.3 A - same value), different package (SMB vs. SMBG) | SMB package has larger footprint and higher RθJA; less suitable for high-density automotive modules | Select SMBG6.0CA-M3/5B when space-constrained layouts or AEC-Q101 validation are mandatory. |
| SMCJ6.0CA | Higher PPPM = 1500 W, larger SMC (DO-214AB) package, VBR min/max = 6.67–7.37 V, same VC = 10.3 V, but no AEC-Q101 listing in base grade | Used in non-automotive industrial power inputs where higher surge margin is needed but space is not constrained | Choose SMBG6.0CA-M3/5B for automotive or compact designs requiring certified reliability; choose SMCJ6.0CA only if >600 W rating is essential and AEC-Q101 is not required. |
Compared with SMBJ6.0CA and SMCJ6.0CA, SMBG6.0CA-M3/5B delivers identical electrical clamping performance in a smaller, automotive-qualified package-enabling higher board density and eliminating need for separate qualification testing in OEM programs.

FAQ
What is the clamping voltage of SMBG6.0CA-M3/5B at its rated peak pulse current?
The SMBG6.0CA-M3/5B has a maximum clamping voltage (VC) of 10.3 V when subjected to 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 and ensures predictable overvoltage limiting for downstream 5 V logic circuits. The SMBG6.0CA-M3/5B maintains this clamping performance across its full operating temperature range from –55 °C to +150 °C.
Is SMBG6.0CA-M3/5B suitable for automotive applications?
Yes, SMBG6.0CA-M3/5B is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and infotainment systems. Its halogen-free (M3) construction, MSL Level 1 rating, and validated performance under temperature cycling, humidity, and high-acceleration stress make it suitable for under-hood and cabin-mounted modules. The SMBG6.0CA-M3/5B meets ISO 7637-2 and ISO 16750-2 surge immunity requirements without derating.
How does the SMBG6.0CA-M3/5B differ from unidirectional variants like SMBG6.0A-M3/5B?
The SMBG6.0CA-M3/5B is bidirectional, meaning it provides symmetrical clamping in both polarities-ideal for AC-coupled or differential signal lines such as CAN, RS-485, or USB. In contrast, SMBG6.0A-M3/5B is unidirectional and includes a cathode band marking; it conducts only in reverse bias and requires correct polarity placement. Both share identical VWM, VBR, and PPPM, but the SMBG6.0CA-M3/5B eliminates polarity dependency in layout design.
What is the thermal resistance of SMBG6.0CA-M3/5B, and how does it affect PCB layout?
The SMBG6.0CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding thermal vias reduces RθJA and improves surge endurance. For repeated surge events, designers should verify junction temperature rise using SMBG6.0CA-M3/5B's 150 °C TJmax limit and derating curves in Figure 2 of the datasheet.
Does SMBG6.0CA-M3/5B have UL recognition, and what does that mean for system certification?
Yes, SMBG6.0CA-M3/5B carries UL recognition under file E136766 for both unidirectional and bidirectional devices, complying with UL 497B for signal circuit protectors. This means the SMBG6.0CA-M3/5B has been independently evaluated for safety-related parameters including flammability (UL 94 V-0 molding compound), surge withstand, and insulation integrity. System designers can leverage this recognition to streamline end-equipment safety certifications, particularly in industrial and telecom applications requiring UL listing.
