Product details
Overview
SMBJ6.0C-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for primary overvoltage protection of sensitive ICs, MOSFETs, and signal lines in power rails and interface circuits. 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 peak surge current - deployed in industrial sensor interfaces and DC power input stages.
For engineers reviewing the SMBJ6.0C-E3/5B datasheet, SMBJ6.0C-E3/5B pinout, SMBJ6.0C-E3/5B application, or SMBJ6.0C-E3/5B equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and direct alternatives for ESD/lightning transient protection in 5–24 V systems.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR. Its low incremental surge resistance (typical <0.2 Ω) ensures minimal voltage overshoot during fast transients, while its 10/1000 µs waveform rating reflects standardized lightning-surge immunity testing per IEC 61000-4-5.
Designed for surface-mount assembly on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it achieves 100 °C/W junction-to-ambient thermal resistance and supports repetitive surge duty cycles up to 0.01 %. The unidirectional polarity (cathode band marked) enables asymmetric protection in DC-biased lines without forward conduction during normal operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage exceeds 800 µA; sets upper limit for safe DC bias in protected line. |
| VBR @ IT = 10 mA | 6.67–7.37 V - Measured breakdown range confirming reliable turn-on margin above VWM; ensures robust noise immunity. |
| VC @ IPPM = 58.3 A | ≤10.3 V - Clamped voltage during 600 W surge; defines maximum stress imposed on downstream components. |
| PPPM | 600 W - Peak pulse power handling capability with 10/1000 µs waveform; qualifies for Level 3/4 IEC 61000-4-5 surge immunity. |
| IPPM | 58.3 A - Peak surge current supported at rated clamping voltage; determines minimum trace width and pad area required. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive or high-ambient industrial environments. |
| RθJA | 100 °C/W - Thermal resistance junction-to-ambient on standard 0.2" × 0.2" copper pads; informs layout cooling requirements. |

Applications
| Industrial Sensor Interface | DC Power Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between signal line and ground, activated only during overvoltage events. Use Value: Limits induced transients to ≤10.3 V, preventing latch-up or gate oxide damage in precision ADCs and level translators. |
Use Scenario: Safeguarding 5 V or 12 V DC input rails of embedded controllers against load dump and inductive kickback in factory automation equipment. IC Role / Device Role / Timing Role: Primary overvoltage suppressor mounted directly at connector entry point, upstream of bulk capacitance and LDO regulator. Use Value: Absorbs 600 W surges without degradation, maintaining system uptime and eliminating need for redundant fusing. |
| Automotive Body Control Module | Telecom Line Interface |
|
Use Scenario: Securing LIN bus lines and switched 12 V outputs in door modules and lighting controllers subjected to ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS connected between LIN data line and chassis ground, with cathode tied to LIN. Use Value: Clamps 100 V/50 ms pulses to <12 V, preserving signal integrity and meeting OEM EMC test requirements. |
Use Scenario: Shielding RS-485/RS-232 transceiver inputs in base station backhaul equipment from lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing fast-response clamping for residual transients. Use Value: Responds in <1 ns to sub-microsecond spikes, limiting voltage across transceiver pins to safe levels below absolute maximum ratings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0A-E3/5B | Unidirectional variant with identical VWM, VBR, and PPPM; same SMB package and marking code KG. | No functional difference - SMBJ6.0C-E3/5B and SMBJ6.0A-E3/5B are identical in specification and performance per Vishay documentation. | Select SMBJ6.0A-E3/5B if ordering system requires legacy part number format; both are drop-in replacements. |
| SMCJ6.0A-E3/57T | Higher 1500 W PPPM, larger SMC (DO-214AB) package, 10× higher IPPM (101 A), same VC (10.3 V). | Better suited for high-energy surges (e.g., 4 kV IEC 61000-4-5) but requires larger PCB footprint and thermal management. | Choose SMCJ6.0A-E3/57T only when surge threat level exceeds 600 W; otherwise SMBJ6.0C-E3/5B offers optimal size/power balance. |
Compared with SMBJ6.0A-E3/5B, the SMBJ6.0C-E3/5B is functionally identical and interchangeable; compared with SMCJ6.0A-E3/57T, it trades surge capacity for compactness and lower thermal mass - making SMBJ6.0C-E3/5B ideal for space-constrained 5–12 V protection where 600 W rating suffices.

FAQ
What is the clamping voltage of SMBJ6.0C-E3/5B at its rated peak pulse current?
The SMBJ6.0C-E3/5B clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 58.3 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ6.0C-E3/5B maintains this clamping performance across its specified operating temperature range and is validated per JEDEC and IEC test protocols.
Is SMBJ6.0C-E3/5B unidirectional or bidirectional?
SMBJ6.0C-E3/5B is a unidirectional transient voltage suppressor, indicated by the "A" suffix in the family designation and confirmed by its cathode band marking. It conducts only in reverse bias during overvoltage events and blocks forward current up to 3.5 V at 50 A. Bidirectional variants use the "CA" suffix (e.g., SMBJ6.0CA) and lack polarity marking - the SMBJ6.0C-E3/5B must be oriented correctly on PCBs with cathode toward the protected line.
What package type does SMBJ6.0C-E3/5B use, and what are its key mechanical features?
SMBJ6.0C-E3/5B uses the SMB (DO-214AA) surface-mount package: 4.06 mm × 4.57 mm body, 2.18 mm height, with matte tin-plated leads solderable per J-STD-002. Its molding compound meets UL 94 V-0, and it complies with MSL level 1 (peak reflow temperature 260 °C). The SMBJ6.0C-E3/5B's low profile and standardized pad layout enable high-yield automated assembly and thermal performance matching Vishay's published RθJA = 100 °C/W.
Does SMBJ6.0C-E3/5B meet automotive qualification standards?
The base SMBJ6.0C-E3/5B is commercial-grade and RoHS-compliant (E3 suffix), but not AEC-Q101 qualified. For automotive use, Vishay offers the SMBJ6.0AHE3_B variant (HE3 suffix), which is AEC-Q101 qualified and shares identical electrical specs. The SMBJ6.0C-E3/5B itself is used in non-safety-critical automotive applications where qualification is not mandated, but design teams requiring formal validation should specify the HE3 version.
How does SMBJ6.0C-E3/5B compare to SMAJ6.0A in terms of surge capability and footprint?
SMBJ6.0C-E3/5B delivers the same 600 W peak pulse power and 10.3 V clamping voltage as SMAJ6.0A but in a larger SMB package (vs. SMA/DO-214AC), offering 30 % higher thermal mass and improved surge endurance under repeated stress. Its 0.220" × 0.130" footprint accommodates higher current density than SMAJ6.0A, making SMBJ6.0C-E3/5B preferable for industrial environments with frequent transients - while retaining compatibility with standard SMT placement equipment.
