Product details
Overview
SMBJ6.0A-E3/5B 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-E3/5B datasheet, SMBJ6.0A-E3/5B pinout, SMBJ6.0A-E3/5B application, or SMBJ6.0A-E3/5B equivalent, key selection criteria include its unidirectional polarity, SMB (DO-214AA) package compatibility with automated SMT placement, 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-biased 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 ns), critical for suppressing ESD and inductive switching spikes.
The device is rated for 100 A non-repetitive forward surge (8.3 ms half-sine), 150 °C max junction temperature, and thermal resistance RθJA = 100 °C/W on standard 0.2" × 0.2" copper pads - enabling robust operation in compact, thermally constrained PCB layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 6.67 V / 7.37 V at 10 mA - Ensures reliable turn-on margin above VWM with tight tolerance |
| VC @ IPPM | ≤10.3 V at 58.3 A - Low clamping voltage limits stress on protected ICs during 600 W surges |
| IPPM | 58.3 A (10/1000 µs) - Peak surge current capacity compatible with IEC 61000-4-5 Level 3/4 testing |

| TJ max | +150 °C - Supports operation in automotive engine compartments and industrial enclosures |
| Package | SMB (DO-214AA) - Standardized 2-pin SMD footprint with 0.220" x 0.155" body and matte tin leads |

|---|---|
Use Scenario: Protection of gate drivers and feedback sensing circuits against voltage spikes from IGBT/MOSFET switching in 24 V DC motor inverters. IC Role / Device Role / Timing Role: Shunt TVS placed directly across power FET gate-source terminals to clamp Miller-induced overshoot and prevent false turn-on. Use Value: Clamping at ≤10.3 V prevents gate oxide breakdown in 20 V-rated MOSFETs while surviving repetitive 600 W surges per IEC 61800-3. | Use Scenario: Input protection for LIN bus transceivers and window lift control ICs exposed to load dump and jump-start events in 12 V vehicle systems. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN line and chassis ground to absorb negative-going transients up to -100 V. Use Value: Withstands 100 A surge (8.3 ms) and maintains <1 µA leakage at 13.5 V, ensuring no impact on LIN bus idle-state voltage integrity. |
| Consumer Power Adapters | Industrial Sensor Signal Conditioning |
Use Scenario: Secondary-side overvoltage suppression on 5 V USB-C PD output rails subjected to transformer ringing and hot-plug transients. IC Role / Device Role / Timing Role: TVS placed after DC-DC converter output filter to clamp fast-rising spikes before reaching USB port controller ICs. Use Value: Sub-1 ns response and 10.3 V clamping ensure protected SoCs remain within 6 V absolute max rating even during 500 V/µs edge rates. | Use Scenario: Protection of analog front-end inputs (e.g., 4–20 mA loop receivers) in PLC I/O modules exposed to field wiring ESD and surge coupling. IC Role / Device Role / Timing Role: Series-connected TVS on signal line with series resistor to limit current into precision amplifier input stage. Use Value: 6.0 V VWM allows full 0–24 V signal range while clamping transients to <10.3 V, preserving ADC accuracy and preventing latch-up. |
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 | Bidirectional variant; symmetric ±6.0 V VWM, same VBR and PPPM | Required for AC-coupled or differential signal lines (e.g., RS-485, CAN) where polarity reversal occurs | Select SMBJ6.0CA-E3/5B only when bidirectional clamping is needed; SMBJ6.0A-E3/5B is optimal for DC rails with defined polarity. |
| SMCJ6.0A-E3/57T | Larger SMC (DO-214AB) package; 1500 W PPPM, higher IPPM = 123 A, same VWM/VC | Used where higher surge endurance is required (e.g., outdoor telecom power inputs) and board space permits larger footprint | Choose SMCJ6.0A-E3/57T for >1000 W surge immunity; SMBJ6.0A-E3/5B remains preferred for space-constrained 600 W applications. |
Compared with SMBJ6.0CA-E3/5B and SMCJ6.0A-E3/57T, the SMBJ6.0A-E3/5B offers the optimal balance of 600 W surge capability, compact SMB footprint, and unidirectional clamping for cost-sensitive DC power rail protection - delivering verified performance where polarity is fixed and board area is limited.

FAQ
What is the maximum clamping voltage of the SMBJ6.0A-E3/5B under surge conditions?
The SMBJ6.0A-E3/5B has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current (IPPM) of 58.3 A using the standard 10/1000 µs waveform. This value is guaranteed per Vishay's datasheet (Document Number 88392, Rev. 09-Jan-2024) and reflects worst-case device behavior under surge stress, ensuring protected circuitry remains within safe voltage limits.
Is the SMBJ6.0A-E3/5B suitable for automotive applications?
The SMBJ6.0A-E3/5B itself is commercial-grade (RoHS-compliant, E3 suffix), but Vishay offers AEC-Q101 qualified versions under the HE3 suffix (e.g., SMBJ6.0AHE3_B/I). For automotive use, specify the HE3 variant; the SMBJ6.0A-E3/5B is appropriate for non-safety-critical industrial or consumer applications where AEC-Q101 is not mandated.
What does the "-E3/5B" suffix indicate in SMBJ6.0A-E3/5B?
The "-E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "/5B" specifies packaging in 13-inch diameter plastic tape and reel, with a base quantity of 3200 units. This format supports high-volume automated SMT assembly and is distinct from the 7-inch reel option (/52) used for smaller batch prototyping.
How does the SMBJ6.0A-E3/5B compare to the SMBJ5.0A-E3/5B in terms of voltage ratings?
The SMBJ6.0A-E3/5B has a 6.0 V stand-off voltage (VWM) and 6.67–7.37 V breakdown range, versus the SMBJ5.0A-E3/5B's 5.0 V VWM and 6.40–7.07 V VBR. Both share identical 600 W PPPM, 10.3 V VC, and SMB package - making SMBJ6.0A-E3/5B the correct choice for 6 V nominal rails where tighter margin above VWM is needed to avoid leakage-induced power loss.
Can the SMBJ6.0A-E3/5B be used in bidirectional signal protection?
No - the SMBJ6.0A-E3/5B is unidirectional and must be oriented with cathode toward the protected line to function correctly. For bidirectional protection (e.g., RS-232, audio lines), use the SMBJ6.0CA-E3/5B variant, which provides symmetrical clamping for both positive and negative transients without polarity constraints.
