Product details
Overview
SMBJ6.0HE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed to protect sensitive electronics against ESD, lightning-induced surges, and inductive switching transients. 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.
For engineers reviewing the SMBJ6.0HE3/5B datasheet, SMBJ6.0HE3/5B pinout, SMBJ6.0HE3/5B application, or SMBJ6.0HE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, low clamping voltage, unidirectional polarity with cathode band marking, and suitability for automotive power line and sensor interface protection where robust surge immunity and RoHS-compliant, halogen-free construction are required.
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 glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ps), enabling effective suppression of sub-nanosecond ESD events per IEC 61000-4-2 Level 4.
The SMBJ6.0HE3/5B is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), has a maximum junction temperature of +150 °C, and exhibits a low thermal resistance of 20 °C/W (junction-to-lead), supporting reliable operation under repeated surge stress when mounted on recommended 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.0 V - Maximum continuous reverse operating voltage before clamping begins; sets threshold for protection activation without leakage interference. |
| VBR (Breakdown Voltage) | 6.67–7.37 V at 10 mA - Confirmed avalanche onset range; ensures predictable turn-on margin above VWM for noise immunity. |
| VC (Clamping Voltage) | ≤10.3 V at 58.3 A (10/1000 µs) - Actual maximum voltage seen by protected IC during worst-case surge; enables safe margin for 5 V logic rails. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy-handling capability under standardized 10/1000 µs waveform; supports industrial-grade surge immunity. |
| IPPM (Peak Pulse Current) | 58.3 A - Measured surge current at VC; defines maximum transient current the device can shunt without failure. |
| TJmax | +150 °C - Maximum junction temperature rating; allows operation in under-hood automotive environments and high-ambient industrial settings. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 2.20 mm × 3.94 mm body; compatible with automated pick-and-place and reflow soldering. |

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-E3/5B | Commercial-grade (non-AEC-Q101), same VWM, VBR, VC, and PPPM; RoHS-compliant but not halogen-free. | Lacks automotive qualification; suitable for consumer or industrial designs without AEC compliance mandates. | Select SMBJ6.0A-E3/5B when cost optimization is prioritized and automotive reliability testing is not required. |
| SMBJ6.0CA-E3/5B | Bidirectional variant; identical VWM and VBR range but symmetric clamping in both polarities; no polarity marking. | Used where AC-coupled signals or bidirectional data lines (e.g., RS-485) require symmetrical transient suppression. | Choose SMBJ6.0CA-E3/5B only when protecting balanced interfaces-SMBJ6.0HE3/5B is not interchangeable due to unidirectional polarity. |
Compared with SMBJ6.0A-E3/5B and SMBJ6.0CA-E3/5B, the SMBJ6.0HE3/5B uniquely combines AEC-Q101 qualification, halogen-free construction, and unidirectional clamping-making it the sole option for automotive 12 V power rail protection requiring full PPAP compliance and environmental certification.

FAQ
What is the clamping voltage of SMBJ6.0HE3/5B at its rated peak pulse current?
The SMBJ6.0HE3/5B has a maximum clamping voltage (VC) of 10.3 V when subjected to its rated peak pulse current of 58.3 A under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and ensures predictable overvoltage limiting for downstream 5 V logic and analog components. The SMBJ6.0HE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ6.0HE3/5B suitable for automotive applications?
Yes, SMBJ6.0HE3/5B is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, body electronics, and infotainment systems. Its HE3 suffix denotes RoHS-compliant, halogen-free, and AEC-Q101-qualified construction. The SMBJ6.0HE3/5B meets stringent requirements for temperature cycling, mechanical shock, and long-term reliability in under-hood and cabin environments.
How does the SMBJ6.0HE3/5B differ from the SMBJ6.0A-E3/5B?
The SMBJ6.0HE3/5B adds AEC-Q101 qualification and halogen-free material compliance to the baseline SMBJ6.0A-E3/5B specification. Both share identical electrical parameters (VWM, VBR, VC, PPPM), but SMBJ6.0HE3/5B undergoes extended stress testing for automotive deployment. The SMBJ6.0HE3/5B is the appropriate choice when PPAP documentation, zero-halogen requirements, or automotive-grade traceability are mandated.
What is the mounting pad layout recommendation for SMBJ6.0HE3/5B?
Vishay specifies a minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad area for each terminal of the SMBJ6.0HE3/5B to achieve rated thermal and surge performance. This layout ensures adequate heat dissipation and current spreading during 10/1000 µs transients. Deviating from this pad size reduces peak pulse current capability and may compromise long-term reliability under repetitive surge stress.
Does SMBJ6.0HE3/5B have polarity marking, and how is it identified?
Yes, SMBJ6.0HE3/5B is unidirectional and features a visible cathode band on the case body-consistent with DO-214AA standard marking. The banded end connects to the cathode terminal, which must be tied to the protected line (e.g., 5 V rail), while the anode connects to ground. This polarity is critical: reverse orientation prevents proper clamping and may cause catastrophic failure during surge events. The SMBJ6.0HE3/5B does not support bidirectional operation.
