Product details
Overview
SMB10J16AHE3_B/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 power 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 sensor interfaces and industrial power supply rails.
For engineers reviewing the SMB10J16AHE3_B/I datasheet, SMB10J16AHE3_B/I pinout, SMB10J16AHE3_B/I application, or SMB10J16AHE3_B/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 device that diverts transient energy away from sensitive downstream circuitry using an avalanche breakdown mechanism. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress, while its MSL Level 1 rating supports lead-free reflow up to 260 °C peak temperature.
The SMB10J16AHE3_B/I is optimized for fast response (<1 ns) to ESD and lightning-induced transients per IEC 61000-4-2/4-5, with thermal resistance RθJA = 72 °C/W and RθJL = 20 °C/W enabling effective heat dissipation in compact PCB layouts - critical for space-constrained automotive ECUs and industrial controllers.

Applications
| Automotive Sensor Interface | Industrial Power Supply Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between signal line and ground, absorbing transients before they reach the IC input stage. Use Value: Prevents latch-up or permanent damage to automotive-grade microcontrollers and transceivers during 12 V system load dump events (ISO 7637-2 Pulse 5a). | Use Scenario: Safeguarding DC-DC converter inputs in PLC modules and motor drives exposed to inductive switching noise and AC line surges. IC Role / Device Role / Timing Role: Primary surge suppression device across input rails, coordinated with upstream fuses and downstream filtering capacitors. Use Value: Limits peak voltage to ≤26.0 V during 1000 W transients, preserving input-stage MOSFETs and controller ICs rated for 30 V max. |
| Consumer USB Power Delivery | Telecom Base Station Control Lines |
Use Scenario: Protecting USB-C PD port VBUS lines in portable chargers and docking stations against hot-plug transients and cable ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS placed directly at connector, shunting surge current to ground before reaching buck controller or load switch. Use Value: Maintains 16 V operating margin while clamping to 26.0 V - compatible with 20 V PD3.1 specifications and avoids false overvoltage shutdown. | Use Scenario: Shielding RS-485/RS-232 control lines in outdoor telecom cabinets from lightning-induced surges and ground potential differences. IC Role / Device Role / Timing Role: Bidirectional-capable variant not applicable; this unidirectional part used on DC-coupled bias rails feeding line drivers. Use Value: Delivers 38.5 A surge current handling with <1 ns response, meeting Telcordia GR-1089-CORE Level 3 surge immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM (16 V), identical SMB package, but commercial-grade (non-AEC-Q101), RθJA = 72 °C/W | Lacks automotive qualification; suitable for consumer/industrial use only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| SMAJ16AHE3_A/H | Lower PPPM (400 W), SMA package (smaller footprint), same VWM and AEC-Q101 qualification | Reduced surge handling; used where board space is constrained and threat level is lower | Choose for space-limited designs accepting reduced surge margin, e.g., wearable electronics or secondary protection stages |
Compared with SMBJ16A-E3/52 and SMAJ16AHE3_A/H, the SMB10J16AHE3_B/I delivers automotive-grade reliability with full 1000 W surge capacity in the industry-standard SMB outline - making it optimal for primary protection in harsh-environment applications where both qualification and energy handling are non-negotiable.

FAQ
What is the clamping voltage of SMB10J16AHE3_B/I at its rated peak pulse current?
The SMB10J16AHE3_B/I has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current (IPPM) of 38.5 A under the standard 10/1000 µs waveform. This value is measured at TJ = 25 °C and ensures protected circuitry remains below critical overvoltage thresholds during surge events. The SMB10J16AHE3_B/I datasheet specifies this parameter in the unidirectional electrical characteristics table on page 2.
Is SMB10J16AHE3_B/I qualified for automotive applications?
Yes, SMB10J16AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's documentation (Document Number 88422, Revision 09-Jan-2024). The "HE3" suffix denotes RoHS-compliant and AEC-Q101 qualified construction, validated for temperature cycling, highly accelerated life testing, and surge endurance in automotive environments. This makes SMB10J16AHE3_B/I suitable for under-hood and cabin ECU designs.
What does the "_B/I" suffix mean in SMB10J16AHE3_B/I?
The "_B/I" suffix in SMB10J16AHE3_B/I indicates packaging configuration: "B" denotes the revision code (e.g., revision B of the base design), and "I" specifies the delivery mode - 13-inch diameter plastic tape and reel with 3200 units per reel. This matches Vishay's ordering information table on page 3 of Document 88422, confirming SMB10J16AHE3_B/I is supplied in high-volume SMT-ready format.
How does SMB10J16AHE3_B/I differ from bidirectional TVS diodes like SMB8J16CA?
SMB10J16AHE3_B/I is unidirectional, featuring a cathode band and conducting only in reverse avalanche mode, whereas SMB8J16CA is bidirectional with symmetrical clamping in both polarities. The SMB10J16AHE3_B/I offers 1000 W PPPM vs. 800 W for SMB8J16CA and is optimized for DC-biased lines like power rails; SMB8J16CA suits AC-coupled or floating signal paths such as data lines. Both share the same VWM and VBR range but differ in surge rating and polarity architecture.
What is the thermal resistance of SMB10J16AHE3_B/I, and how does it affect layout design?
SMB10J16AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W and junction-to-lead (RθJL) of 20 °C/W, per Vishay's thermal characteristics table. These values require minimum 5.0 mm × 5.0 mm copper pads per terminal (as specified in the mechanical data) to maintain safe junction temperatures during repeated surges. Insufficient copper area increases thermal impedance, risking premature thermal runaway during high-duty-cycle transients - a critical consideration in SMB10J16AHE3_B/I PCB layout.
