Product details
Overview
SMB10J16AHE3_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 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 38.5 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs, industrial sensor interfaces, and power supply input stages.
For engineers reviewing the SMB10J16AHE3_A/I datasheet, SMB10J16AHE3_A/I pinout, SMB10J16AHE3_A/I application, or SMB10J16AHE3_A/I equivalent, key selection criteria include AEC-Q101 qualification, unidirectional polarity with cathode band marking, thermal resistance (RθJA = 72 °C/W), and compliance with IEC 61000-4-5 surge immunity requirements for harsh environments.
Technical Context
This TVS diode operates as a clamping-type overvoltage protector, leveraging an avalanche breakdown mechanism to limit transient voltages before they damage downstream ICs or MOSFETs. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables rapid energy dissipation during 8.3 ms half-sine or 10/1000 µs surges.
The device is rated for -55 °C to +150 °C operating junction temperature, meets MSL Level 1 per J-STD-020, and supports automated SMT placement with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102. Its SMB package provides 0.220" × 0.130" footprint with 0.086" height and UL 94 V-0 molding compound.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-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 where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and no vehicle OEM approval is needed. |
| 1.5SMC16A | Higher-power SMC package (1500 W PPPM), same 16 V VWM, but larger footprint (7.11 mm × 6.22 mm) and higher RθJA (50 °C/W). | Better surge endurance for rare high-energy events, but requires PCB area increase and may need thermal relief. | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 or repeated 1000 W pulses are expected. |
Compared with SMBJ16A-E3/52, SMB10J16AHE3_A/I adds AEC-Q101 validation and extended temperature capability; versus 1.5SMC16A, it trades power headroom for compact SMB footprint and lower profile - ideal for space-constrained automotive modules.

FAQ
What is the clamping voltage of SMB10J16AHE3_A/I and how is it measured?
The SMB10J16AHE3_A/I has a maximum clamping voltage (VC) of 26.0 V, measured at a peak pulse current (IPPM) of 38.5 A using the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed per Vishay's datasheet Document Number 88422 and reflects the voltage across the device terminals during worst-case transient conditions - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMB10J16AHE3_A/I suitable for automotive applications?
Yes, SMB10J16AHE3_A/I is AEC-Q101 qualified and manufactured with automotive-grade process controls, including MSL Level 1 moisture sensitivity and extended temperature operation from -55 °C to +150 °C. Its HE3 suffix explicitly denotes AEC-Q101 compliance, making SMB10J16AHE3_A/I appropriate for engine control, body electronics, and ADAS subsystems where reliability under thermal and electrical stress is mandatory.
What does the "HE3_A/I" suffix mean in SMB10J16AHE3_A/I?
The "HE3" suffix indicates RoHS-compliant construction with AEC-Q101 qualification; "A" is the revision code per Vishay's internal documentation; and "I" denotes packaging in 13-inch tape-and-reel format with 3200 units per reel. This full suffix confirms SMB10J16AHE3_A/I meets automotive reliability standards and ships in high-volume SMT-ready format.
How does SMB10J16AHE3_A/I compare to bidirectional TVS diodes like SMB8J16CA?
SMB10J16AHE3_A/I is unidirectional and optimized for DC rail protection where polarity is fixed (e.g., +12 V to GND), offering 1000 W PPPM. In contrast, SMB8J16CA is bidirectional (±16 V symmetric clamping), rated for 800 W PPPM, and used in AC-coupled or floating signal lines. SMB10J16AHE3_A/I provides higher surge capacity and lower clamping voltage in its intended polarity direction, but cannot protect against negative-going transients.
What is the thermal resistance of SMB10J16AHE3_A/I and how does it affect layout design?
SMB10J16AHE3_A/I 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 value directly impacts sustained surge duty cycle: for repeated 1000 W pulses, designers must ensure adequate copper area and possible thermal vias to avoid exceeding +150 °C junction temperature - verified using Vishay's Fig. 2 derating curve in datasheet 88422.
