Product details
Overview
SMBJ10CHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 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 (PPPM) with 10/1000 µs waveform - deployed on power rails and signal lines of industrial sensors and automotive ECUs.
For engineers reviewing the SMBJ10CHE3/5B datasheet, SMBJ10CHE3/5B pinout, SMBJ10CHE3/5B application, or SMBJ10CHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 to +150 °C), and RoHS-compliant packaging details - all critical for ESD/surge protection design-in and automotive-grade BOM validation.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to divert transient energy away from protected circuitry. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance under repetitive 10/1000 µs surges at 0.01% duty cycle.
The SMBJ10CHE3/5B is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports −55 °C to +150 °C operating junction temperature, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak - confirming suitability for automated SMT assembly in high-reliability industrial and automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-E3/5B | Commercial-grade (non-AEC-Q101), identical electrical specs and SMB package. | Lacks automotive qualification; suitable for industrial/commercial designs without automotive compliance mandates. | Select when AEC-Q101 is not required and cost optimization is prioritized. |
| SMAJ10AHE3/A | Lower PPPM (400 W), SMA (DO-214AC) package, same VWM/VBR/VC ratings. | Reduced surge handling; used where space constraints favor smaller SMA footprint over SMB. | Choose only if system-level surge testing confirms 400 W is sufficient and PCB layout allows SMA placement. |
Compared with SMBJ10A-E3/5B, the SMBJ10CHE3/5B adds AEC-Q101 qualification without electrical trade-offs, while SMAJ10AHE3/A sacrifices 33% peak power rating for smaller size - making SMBJ10CHE3/5B optimal for automotive-critical 12 V rail protection where both robustness and compliance are mandatory.

FAQ
What does the "HE3" suffix indicate in SMBJ10CHE3/5B?
The "HE3" suffix in SMBJ10CHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade variants like SMBJ10A-E3/5B. This certification validates performance under automotive-grade stress tests including high-temperature operating life, temperature cycling, and electrostatic discharge - confirming SMBJ10CHE3/5B is approved for use in safety-critical vehicle subsystems such as body control modules and ADAS camera power supplies.
How does SMBJ10CHE3/5B differ from bidirectional versions like SMBJ10CA?
SMBJ10CHE3/5B is unidirectional, with polarity marked by a cathode band and intended for DC rail protection where current flows in one direction. In contrast, SMBJ10CA is bidirectional, lacks polarity marking, and protects AC or differential signal lines like RS-485 or CAN bus. The SMBJ10CHE3/5B has a forward voltage drop (VF ≤ 3.5 V at 50 A), while SMBJ10CA exhibits symmetrical clamping in both directions - making SMBJ10CHE3/5B unsuitable for AC applications but optimal for 12 V automotive power line clamping.
What is the maximum clamping voltage of SMBJ10CHE3/5B and under what test condition?
The maximum clamping voltage (VC) of SMBJ10CHE3/5B is 17.0 V, measured at a peak pulse current (IPPM) of 35.3 A using the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and reflects worst-case voltage seen by protected circuitry during transient events - a key parameter for ensuring downstream ICs remain within their absolute maximum voltage ratings during surge conditions.
Is SMBJ10CHE3/5B compatible with lead-free reflow soldering processes?
Yes, SMBJ10CHE3/5B meets J-STD-020 MSL Level 1 and is qualified for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 for solderability, and the molding compound is UL 94 V-0 rated. These attributes ensure reliable attachment during standard SMT assembly without popcorn cracking or intermetallic degradation - critical for high-yield manufacturing of automotive and industrial PCBs.
What PCB layout guidance applies to SMBJ10CHE3/5B for optimal thermal and electrical performance?
For optimal performance, SMBJ10CHE3/5B must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Larger copper areas improve heat dissipation and reduce RθJA below the typical 100 °C/W, while short, wide traces minimize inductance that could elevate clamping voltage during fast transients. Avoid routing high-dI/dt signals near the device, and place SMBJ10CHE3/5B as close as possible to the protected IC's power pin to maximize protection effectiveness.
