Product details
Overview
SMB10J6.0AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on 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, 1000 W peak pulse power (10/1000 µs), 97.1 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge - ideal for protecting automotive sensor interfaces and industrial I/O circuits.
For engineers reviewing the SMB10J6.0AHE3/5B datasheet, SMB10J6.0AHE3/5B pinout, SMB10J6.0AHE3/5B application, or SMB10J6.0AHE3/5B equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low clamping voltage under 10.3 V, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below VWM = 6.0 V and rapidly transitions to low-impedance conduction above VBR (min 6.67 V), limiting transient overvoltages to ≤10.3 V at 97.1 A. Its glass-passivated junction ensures stable leakage (<1000 µA at VWM) and robust surge handling per IEC 61000-4-5.
Designed for automotive-grade reliability, SMB10J6.0AHE3/5B meets AEC-Q101 stress tests including temperature cycling, humidity bias, and mechanical shock. Its MSL Level 1 rating (260 °C reflow peak) and matte tin-plated leads support lead-free assembly without whisker risk or solderability degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ6.0AHE3/5B | Same SMB package, identical VWM/VBR/VC, but rated for 600 W PPPM (vs. 1000 W) | Limited to lower-energy transients; not suitable for automotive load-dump or industrial motor-switching scenarios | Select SMB10J6.0AHE3/5B when 1000 W surge immunity is required; SMBJ6.0AHE3/5B suffices for basic ESD + low-energy surge. |
| SMCJ6.0AHE3/5B | Same electrical specs but in larger SMC (DO-214AB) package; higher thermal mass, RθJA = 35 °C/W vs. 72 °C/W | Better sustained power handling but requires 30% more PCB area; less suitable for space-constrained automotive modules | Choose SMB10J6.0AHE3/5B for tight layouts where 1000 W must fit in SMB footprint; SMCJ6.0AHE3/5B preferred for high-temperature ambient designs. |

FAQ
What is the clamping voltage of SMB10J6.0AHE3/5B at its rated peak pulse current?
The SMB10J6.0AHE3/5B clamps to a maximum of 10.3 V when subjected to its rated peak pulse current of 97.1 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 and ensures downstream 5 V logic circuits remain within safe operating limits during surge events. The clamping voltage is guaranteed across the full operating temperature range and forms the basis for system-level overvoltage margin calculations in designs using SMB10J6.0AHE3/5B.
Is SMB10J6.0AHE3/5B suitable for automotive applications?
Yes, SMB10J6.0AHE3/5B is explicitly AEC-Q101 qualified and manufactured with automotive-grade process controls, including stress testing for temperature cycling, humidity bias, and mechanical shock. Its RoHS-compliant HE3 suffix denotes AEC-Q101 qualification, and it is commonly deployed in engine control units, body control modules, and ADAS sensor interfaces. Engineers selecting SMB10J6.0AHE3/5B for automotive use can rely on its validated performance under ISO 7637-2 and ISO 16750-2 transient conditions.
What does the "HE3/5B" suffix indicate in SMB10J6.0AHE3/5B?
The "HE3" suffix in SMB10J6.0AHE3/5B indicates RoHS-compliant construction with AEC-Q101 qualification, while "5B" specifies packaging in 13-inch diameter plastic tape and reel with a base quantity of 3200 units. This ordering code ensures traceability to Vishay's automotive-grade production lot and guarantees compliance with J-STD-020 MSL Level 1 reflow requirements. The full part number SMB10J6.0AHE3/5B thus identifies both reliability grade and logistics configuration for procurement and manufacturing planning.
How does SMB10J6.0AHE3/5B differ from bidirectional TVS diodes like SMB8J6.0CAHE3/5B?
SMB10J6.0AHE3/5B is unidirectional and intended for DC line protection where polarity is fixed (e.g., VCC-to-ground), offering 1000 W PPPM and 97.1 A IPPM. In contrast, SMB8J6.0CAHE3/5B is bidirectional, suited for AC or floating signal lines (e.g., RS-485), with 800 W PPPM and 77.7 A IPPM. The unidirectional nature of SMB10J6.0AHE3/5B provides lower leakage and tighter VBR tolerance, making it preferable for precision 5 V rail protection where reverse conduction must be strictly avoided.
What is the thermal resistance of SMB10J6.0AHE3/5B, and how does it affect layout design?
SMB10J6.0AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This relatively high RθJA means effective heat dissipation relies heavily on proper PCB copper area and thermal vias. For reliable 1000 W pulse handling, designers must follow Vishay's recommended pad layout and avoid excessive trace length or narrow traces between SMB10J6.0AHE3/5B terminals and thermal planes to prevent localized overheating during surge events.
