Product details
Overview
SMBJ6.0CA-M3/52 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 a 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 - used in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ6.0CA-M3/52 datasheet, SMBJ6.0CA-M3/52 pinout, SMBJ6.0CA-M3/52 application, or SMBJ6.0CA-M3/52 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), JEDEC-compliant MSL Level 1 handling, and halogen-free RoHS compliance per Vishay's M3 suffix specification.
Technical Context
This device operates as a voltage-clamping protector with symmetrical avalanche breakdown in both directions, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable VBR tolerance (±5% typical), low incremental surge resistance, and fast response time (<1 ns).
Rated for -55 °C to +150 °C operating junction temperature, SMBJ6.0CA-M3/52 is derated above 25 °C ambient per Fig. 2 in the datasheet and supports repetitive surge duty cycles up to 0.01%. It meets UL 497B recognition (QVGQ2) and complies with ANSI/IEEE C62.35 surge waveform standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA test current - defines reliable conduction onset under bidirectional surge conditions |
| VWM | 6.0 V - maximum continuous reverse voltage before leakage exceeds 800 µA, ensuring no false triggering during normal operation |
| VC @ IPPM | ≤10.3 V at 58.3 A - clamping voltage limits downstream IC stress during 600 W transient events |
| PPPM | 600 W (10/1000 µs waveform) - peak surge energy handling capacity for lightning or ESD-induced spikes |
| RθJA | 100 °C/W - thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads, critical for power derating |
| IFSM | Not applicable - bidirectional device has no forward surge rating; only unidirectional variants specify 100 A 8.3 ms half-sine |
| TJ max. | +150 °C - maximum junction temperature defining safe continuous operation and surge repetition limits |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, halogen-free, RoHS-compliant (M3 suffix), MSL Level 1, matte tin-plated terminals solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; common node in bidirectional configuration | No polarity marking; symmetric terminals enable identical clamping for ± transients |
| Cathode | Current exit terminal in forward bias; common node in bidirectional configuration | Identical physical structure to Anode; bidirectional operation eliminates cathode band marking |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) on 12 V systems with margin |
| Low clamping ratio (VC/VWM ≈ 1.72) | Minimizes overvoltage stress on protected ICs compared to higher-ratio TVS devices |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and reflow at 260 °C peak without baking preconditioning |
| UL 497B recognized (QVGQ2) | Validates suitability for telecom and industrial interface protection per safety standards |
Applications
| Industrial Sensor Interfaces | Telecom Line Protection |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 4–20 mA current loops) from inductive switching transients in PLC modules. IC Role / Device Role / Timing Role: Voltage-clamping protector placed across signal and return paths, absorbing energy before it reaches precision DAC or op-amp circuitry. Use Value: Limits transient voltage to ≤10.3 V, preventing latch-up or damage to 12 V-rated signal conditioning ICs while maintaining signal integrity. |
Use Scenario: Shielding RS-485 transceiver I/O pins against lightning-induced surges on outdoor data links. IC Role / Device Role / Timing Role: Bidirectional shunt element connected between differential pair and ground, clamping common-mode and differential-mode transients simultaneously. Use Value: Withstands 600 W surges per line, meeting IEC 61000-4-5 requirements without requiring additional series impedance or filtering. |
| Automotive Body Control Modules | Consumer Appliance Power Inputs |
Use Scenario: Safeguarding LIN bus transceivers and microcontroller GPIOs from load-dump and jump-start transients in vehicle door modules. IC Role / Device Role / Timing Role: Primary front-end clamp on 12 V supply rail and communication lines, activated within <1 ns of overvoltage onset. Use Value: Halogen-free M3 construction satisfies automotive material compliance; 150 °C TJ max supports under-hood deployment. |
Use Scenario: Suppressing ESD and switching noise on AC/DC adapter input lines in smart home hubs and IoT gateways. IC Role / Device Role / Timing Role: Low-capacitance (typ. 1500 pF at 0 V) shunt device across input rectifier outputs, minimizing high-frequency interference. Use Value: 6.0 V VWM aligns with 5 V system rails; bidirectional symmetry avoids polarity errors during board assembly. |
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 but not halogen-free (E3 vs. M3) | Preferred for commercial-grade non-automotive use where halogen content is unrestricted | Select E3 for cost-sensitive consumer designs; M3 required for halogen-free mandates (e.g., EU EcoDesign) |
| SMAJ6.0CA-M3 | Lower PPPM (400 W), larger VC (10.5 V), same VWM/VBR; SMA (DO-214AC) package | Used where PCB space allows larger footprint and 400 W rating suffices (e.g., low-energy control signals) | Choose SMAJ6.0CA-M3 only if layout constraints permit larger package and lower surge margin is acceptable |
Compared with SMBJ6.0CA-E3/52, the M3 variant adds halogen-free compliance without performance trade-offs; versus SMAJ6.0CA-M3, SMBJ6.0CA-M3 delivers 50% higher surge power in a more compact SMB outline - critical for dense industrial PCBs.

FAQ
What is the breakdown voltage range for SMBJ6.0CA-M3/52?
The SMBJ6.0CA-M3/52 has a guaranteed breakdown voltage (VBR) range of 6.4 V to 7.07 V at 10 mA test current, measured bidirectionally per ANSI/IEEE C62.35. This range ensures consistent clamping onset across manufacturing lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Is SMBJ6.0CA-M3/52 suitable for automotive applications?
SMBJ6.0CA-M3/52 is halogen-free and RoHS-compliant but not AEC-Q101 qualified. For automotive use, Vishay offers the HM3 variant (e.g., SMBJ6.0CAHM3_B/H); the M3 suffix alone indicates commercial-grade qualification only. Always verify qualification status via the full ordering code before deploying SMBJ6.0CA-M3/52 in automotive ECUs or ADAS modules.
How does the clamping voltage of SMBJ6.0CA-M3/52 compare to its stand-off voltage?
SMBJ6.0CA-M3/52 clamps to ≤10.3 V at 58.3 A peak current, while its maximum stand-off voltage (VWM) is 6.0 V - yielding a clamping ratio of ~1.72. This low ratio minimizes overvoltage stress on downstream ICs relative to higher-ratio TVS devices, making SMBJ6.0CA-M3/52 especially effective for protecting 5 V or 3.3 V logic interfaces.
What is the thermal resistance of SMBJ6.0CA-M3/52, and how does it affect derating?
The SMBJ6.0CA-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This value dictates power derating above 25 °C ambient: for example, at 75 °C ambient, the allowable continuous power drops to 2.5 W (5.0 W × [1 − (75−25)/100]). Derating curves are provided in Figure 2 of the Vishay datasheet 88392.
Does SMBJ6.0CA-M3/52 have polarity markings on the package?
No - SMBJ6.0CA-M3/52 is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows installation in either orientation on PCBs, eliminating assembly errors associated with unidirectional devices. This simplifies layout and reduces risk in high-volume manufacturing of differential or AC-coupled interfaces.
