Product details
Overview
SMB10J14AHE3_A/I 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 14 V stand-off voltage (VWM), 15.6–17.2 V breakdown voltage (VBR) at 1 mA, 23.2 V clamping voltage (VC) at 43.1 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMB10J14AHE3_A/I datasheet, SMB10J14AHE3_A/I pinout, SMB10J14AHE3_A/I application, or SMB10J14AHE3_A/I equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, leveraging a glass-passivated silicon junction to achieve sub-nanosecond response time and stable clamping under repetitive transients. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked until breakdown threshold is exceeded.
The device complies with ANSI/IEEE C62.35 standards for surge suppression and is rated for operation from –55 °C to +150 °C junction temperature. Thermal resistance is 72 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), supporting reliable power dissipation when mounted per recommended pad layout.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ14A-E3/52 | Same SMB package, identical VWM/VBR/VC specs, but commercial-grade (non-AEC-Q101) and RoHS-compliant only | Lacks automotive qualification; suitable for industrial/commercial designs without AEC validation requirements | Select when cost sensitivity outweighs automotive qualification needs and thermal derating margins allow |
| SMAJ14AHE3_A/I | Smaller SMA (DO-214AC) package, same electrical specs, lower PPPM (400 W), higher RθJA (110 °C/W) | Lower power handling and reduced thermal performance; limited to lower-energy surge environments | Choose only for space-constrained layouts where 400 W peak power suffices and ambient temperature remains <85 °C |
Compared with SMBJ14A-E3/52 and SMAJ14AHE3_A/I, SMB10J14AHE3_A/I uniquely combines AEC-Q101 qualification, 1000 W surge rating, and MSL Level 1 process compatibility - making it the preferred choice for automotive and high-reliability industrial deployments requiring validated long-term robustness.

FAQ
What is the clamping voltage of SMB10J14AHE3_A/I at its rated peak pulse current?
The SMB10J14AHE3_A/I has a maximum clamping voltage (VC) of 23.2 V when subjected to its specified peak pulse current (IPPM) of 43.1 A using the 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry remains below critical overvoltage thresholds during standardized surge events. The SMB10J14AHE3_A/I maintains this clamping performance across its full operating temperature range.
Is SMB10J14AHE3_A/I suitable for automotive applications?
Yes, SMB10J14AHE3_A/I is AEC-Q101 qualified and explicitly designated for automotive use via its HE3 suffix and "automotive ordering code" designation in the Vishay datasheet. It meets requirements for under-hood and cabin modules, including thermal cycling, humidity resistance, and mechanical shock. The SMB10J14AHE3_A/I is commonly deployed in body control modules, ADAS camera power supplies, and infotainment system DC inputs.
What does the 'HE3' and '_A/I' suffix mean in SMB10J14AHE3_A/I?
The 'HE3' suffix indicates RoHS-compliant construction with AEC-Q101 qualification; '_A' denotes the revision code per Vishay's document control, and '/I' specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix confirms the SMB10J14AHE3_A/I part meets automotive reliability standards and ships in high-volume SMT-ready format.
How does SMB10J14AHE3_A/I differ from bidirectional TVS diodes like SMB8J14CA?
SMB10J14AHE3_A/I is unidirectional and blocks reverse current until breakdown, making it ideal for DC-biased lines such as power rails. In contrast, SMB8J14CA is bidirectional with symmetrical clamping in both polarities, suited for AC or floating signal lines. The SMB10J14AHE3_A/I offers higher peak pulse power (1000 W vs. 800 W) and is AEC-Q101 qualified, whereas SMB8J14CA shares the same VWM but lacks automotive validation in standard configurations.
What PCB layout guidance applies to SMB10J14AHE3_A/I for optimal thermal and surge performance?
Vishay specifies mounting SMB10J14AHE3_A/I on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated PPPM and thermal resistance. Trace width should be ≥1.0 mm, and thermal vias under pads are recommended for high-duty-cycle applications. The SMB10J14AHE3_A/I cathode band must align with schematic polarity; incorrect orientation compromises clamping function and may cause catastrophic failure during surge events.
