Product details
Overview
SMBJ10AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping fast-rising ESD and surge transients on power and signal lines. It features 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR) at 1 mA, 17.0 V maximum clamping voltage (VC) at 35.3 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the SMBJ10AHE3_B/H datasheet, SMBJ10AHE3_B/H pinout, SMBJ10AHE3_B/H application, or SMBJ10AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compliance with UL 497B for telecom and automotive electronics protection.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (VBR), limiting transient energy to safe levels for downstream components. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge stress.
Designed for automated SMT assembly, SMBJ10AHE3_B/H meets J-STD-020 MSL Level 1 (peak reflow ≤ 260 °C), has matte tin-plated leads compliant with JESD 22-B102, and supports 100 A non-repetitive forward surge current (IFSM) - enabling robust protection in DC power rails and low-voltage control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 11.1 V / 12.3 V at IT = 1 mA - defines precise avalanche onset range for predictable protection threshold |
| VC @ IPPM | 17.0 V at 35.3 A - clamped voltage during 10/1000 µs surge, determining maximum stress on protected IC |
| PPPM | 600 W - peak transient power handling capability under standard IEC 61000-4-5 waveform |
| ID @ VWM | 5.0 µA max - low reverse leakage ensures minimal standby power loss in battery-powered systems |
| TJ max | +150 °C - enables operation in high-temperature environments such as engine control units |
| RθJA | 100 °C/W - thermal resistance from junction to ambient, critical for derating in enclosed PCB layouts |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with cathode band marking on anode-side end. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); terminals are matte tin-plated for solderability per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or lower-potential rail | Provides reference node for unidirectional clamping - must be tied to system ground for proper transient shunting |
| Cathode | Current exit point in forward bias; marked by band, connected to protected line | Connected to the line being protected (e.g., 12 V supply rail); conducts surge current to ground when V > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per JESD22 standards |
| 600 W peak pulse power | Handles IEC 61000-4-5 Level 4 surges (4 kV line-to-earth) without degradation when mounted per recommended pad layout |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes overvoltage stress on protected devices - e.g., keeps 3.3 V logic inputs below absolute maximum ratings during transients |
| MSL Level 1 rating | Enables single-pass reflow without moisture-induced popcorning, eliminating pre-bake requirements in high-volume manufacturing |
| Glass-passivated junction | Ensures stable VBR and low leakage over 10+ years of field operation in humid industrial environments |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Use Value: Fast response time (<1 ns) prevents data corruption in connected peripherals before USB enumeration completes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/52 | Commercial-grade version; not AEC-Q101 qualified; same electrical specs and SMB package | Lacks automotive qualification - suitable for consumer/industrial but not automotive Tier-1 designs | Select when cost sensitivity outweighs automotive compliance requirements |
| SMBJ10CAHE3_B/H | Bidirectional variant; symmetric VBR (11.1–12.3 V) in both directions; same PPPM and VC | Required for AC-coupled or floating signal lines where polarity reversal occurs (e.g., RS-485, CAN bus) | Choose only if bidirectional clamping is needed - unidirectional SMBJ10AHE3_B/H offers lower leakage in DC applications |
Compared with SMBJ10A-E3/52, SMBJ10AHE3_B/H adds AEC-Q101 qualification for automotive use without changing footprint or electrical behavior; compared with SMBJ10CAHE3_B/H, it provides lower ID (5.0 µA vs. 10 µA) in DC-biased applications due to unidirectional architecture.

FAQ
What is the clamping voltage of SMBJ10AHE3_B/H at its rated peak pulse current?
The SMBJ10AHE3_B/H has a maximum clamping voltage (VC) of 17.0 V at 35.3 A peak pulse current (IPPM), measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in the Vishay datasheet Document Number 88392, page 2. The SMBJ10AHE3_B/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMBJ10AHE3_B/H suitable for automotive applications?
Yes, SMBJ10AHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3" suffix and confirmed in the Vishay ordering information table (page 3 of Document 88392). It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and mechanical shock per JESD22 standards. This makes SMBJ10AHE3_B/H appropriate for under-hood and cabin modules in passenger vehicles and commercial vehicles where reliability under thermal and vibration stress is mandatory.
What is the difference between SMBJ10AHE3_B/H and SMBJ10A-E3/52?
The SMBJ10AHE3_B/H and SMBJ10A-E3/52 share identical electrical characteristics, SMB (DO-214AA) package, and RoHS compliance, but differ in qualification level: SMBJ10AHE3_B/H is AEC-Q101 qualified for automotive use, while SMBJ10A-E3/52 is commercial-grade only. Both use the same 7" tape-and-reel packaging (H code), but SMBJ10AHE3_B/H includes additional process controls and lot-level traceability required for automotive PPAP submissions.
Does SMBJ10AHE3_B/H have a bidirectional variant?
Yes, the bidirectional counterpart is SMBJ10CAHE3_B/H, which uses the "CA" suffix to denote symmetrical clamping in both polarities. Its breakdown voltage (VBR) is 11.1–12.3 V in either direction, matching the unidirectional SMBJ10AHE3_B/H's specification, and it shares the same 600 W PPPM rating and SMB package. However, SMBJ10CAHE3_B/H exhibits higher reverse leakage (10 µA vs. 5.0 µA) at VWM and is intended for AC signal lines like RS-485 or CAN, not DC power rails.
What is the thermal resistance of SMBJ10AHE3_B/H and how does it affect layout?
SMBJ10AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value means each watt of sustained power dissipation raises the junction temperature by 100 °C above ambient - so at 5.0 W rated power, TJ would reach 275 °C without derating. Engineers must apply thermal derating above TA = 25 °C per Figure 2 in the datasheet and ensure adequate copper area to maintain TJ ≤ 150 °C in real-world operation.
