Product details
Overview
SMBJ6.0A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection of DC power rails and signal 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), and clamps transients to ≤10.3 V at 58.3 A, making it suitable for protecting MOSFET gates, microcontroller I/O, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ6.0A-E3/52 datasheet, SMBJ6.0A-E3/52 pinout, SMBJ6.0A-E3/52 application, or SMBJ6.0A-E3/52 equivalent, key selection criteria include its unidirectional polarity, SMB (DO-214AA) package compatibility with automated SMT assembly, low clamping voltage under surge, and AEC-Q101 qualification availability via HE3 suffix variants.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM = 6.0 V, it enters avalanche breakdown to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and fast response time (<1.0 ps), critical for suppressing ESD and inductive switching spikes.
The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine) and 58.3 A peak pulse current (10/1000 µs), with thermal resistance RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads. Its cathode-band marking enables unambiguous PCB orientation during placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before conduction begins; sets protection threshold for 5 V logic rails. |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Confirmed breakdown range ensures reliable triggering without premature conduction. |
| VC @ IPPM | ≤10.3 V at 58.3 A - Clamping voltage limits stress on protected ICs during 600 W transient events. |
| PPPM | 600 W (10/1000 µs) - Peak surge power handling capability meets IEC 61000-4-5 Level 3 requirements. |
| IFSM | 100 A (8.3 ms half-sine) - Withstands high-energy inductive kickback in relay or solenoid drive circuits. |
| TJ max | +150 °C - Enables operation in under-hood automotive and industrial environments with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - Standardized 2-pin SMD footprint with 0.205" × 0.130" body and matte tin-plated leads compliant with J-STD-002. |

Applications
| Industrial Motor Drives | Automotive Body Control Modules |
|---|---|
|
Use Scenario: Protection of gate drivers and feedback sensors against inductive kickback from brushed DC motors. IC Role / Device Role / Timing Role: Shunt TVS placed across motor driver output to clamp flyback voltage spikes before they reach MOSFET gate oxide or op-amp inputs. Use Value: Prevents gate oxide rupture and analog front-end damage by limiting transient voltage to ≤10.3 V during 58.3 A surges. |
Use Scenario: Safeguarding LIN bus transceivers and microcontroller I/O pins from battery load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN line and ground to absorb negative-going spikes while allowing normal bidirectional communication. Use Value: Maintains signal integrity and prevents latch-up by clamping transients below 10.3 V without affecting 12 V nominal bus operation. |
| Consumer Power Adapters | Industrial Sensor Signal Conditioning |
|
Use Scenario: Input-stage protection for AC/DC adapters subjected to mains-borne surges and ESD events. IC Role / Device Role / Timing Role: Primary-side TVS across bulk capacitor input to limit voltage overshoot during surge testing (IEC 61000-4-5). Use Value: Extends adapter lifetime by absorbing 600 W pulses without degradation, verified per UL 497B recognition. |
Use Scenario: Shielding 4–20 mA transmitter outputs and analog sensor inputs from field wiring transients. IC Role / Device Role / Timing Role: Low-leakage (≤800 µA at 6.0 V) TVS placed across signal line and ground to avoid loading precision current loops. Use Value: Preserves measurement accuracy while providing sub-10.3 V clamping during 58.3 A surge events on long cable runs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-M3/52 | Halogen-free, RoHS-compliant variant with identical electrical specs and SMB package. | No functional difference; selected when halogen-free compliance is required for environmental certification. | Choose M3/52 for green manufacturing programs requiring halogen-free materials. |
| SMBJ6.0CA-E3/52 | Bidirectional version with same VWM (6.0 V), VBR (6.4–7.25 V), and VC (10.3 V), but no polarity marking. | Required for AC-coupled or bidirectional signal lines (e.g., RS-485, CAN) where polarity reversal occurs. | Select CA-E3/52 only when protecting symmetrical signals; unidirectional SMBJ6.0A-E3/52 is optimal for DC rails. |
Compared with SMBJ6.0A-M3/52, the E3/52 offers standard RoHS compliance without halogen restrictions; compared with SMBJ6.0CA-E3/52, the unidirectional version provides lower leakage and precise cathode orientation for DC biasing-critical for power rail protection where polarity matters.

FAQ
What is the maximum clamping voltage of SMBJ6.0A-E3/52 under surge conditions?
The SMBJ6.0A-E3/52 has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 58.3 A using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and ensures protected downstream components remain within safe operating limits during transient events. The SMBJ6.0A-E3/52 achieves this clamping performance while maintaining low incremental surge resistance for consistent energy dissipation.
Is SMBJ6.0A-E3/52 suitable for automotive applications?
The base SMBJ6.0A-E3/52 is commercial-grade and RoHS-compliant, but not AEC-Q101 qualified. However, Vishay offers the functionally identical SMBJ6.0AHE3 variant (with HE3 suffix) that is fully AEC-Q101 qualified for automotive use. For body electronics or infotainment systems requiring automotive qualification, SMBJ6.0AHE3 is the appropriate choice; SMBJ6.0A-E3/52 remains valid for non-automotive industrial or consumer designs.
How does SMBJ6.0A-E3/52 differ from SMBJ6.0CA-E3/52?
SMBJ6.0A-E3/52 is unidirectional with a marked cathode band, intended for DC line protection where polarity is fixed. SMBJ6.0CA-E3/52 is bidirectional, with no polarity marking and symmetrical breakdown in both directions-required for AC or differential signal lines like RS-485. Both share identical VWM (6.0 V), VBR, and VC (10.3 V), but SMBJ6.0A-E3/52 exhibits lower reverse leakage (≤800 µA vs. ≤1600 µA for CA version at VWM).
What is the thermal resistance of SMBJ6.0A-E3/52, and how does it affect layout?
The SMBJ6.0A-E3/52 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 minimum recommended pad layout per Vishay's datasheet fig. 6. To maintain safe junction temperature under repeated surges, PCB layout must provide adequate copper area and avoid excessive trace length; insufficient copper increases RθJA and risks thermal runaway during sustained transient activity.
Does SMBJ6.0A-E3/52 meet UL safety standards?
Yes, SMBJ6.0A-E3/52 is Underwriters Laboratories (UL) recognized under file number E136766 for protectors per UL 497B, covering both unidirectional and bidirectional configurations. This recognition confirms compliance for use in secondary circuit protection applications, including telecom and industrial equipment. The UL listing applies to the entire SMBJ family, including SMBJ6.0A-E3/52, and supports system-level safety certifications when properly implemented per manufacturer guidelines.
