Product details
Overview
SMB10J5.0HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, designed for high-energy surge protection on DC power rails and signal lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 1000 W peak pulse power (10/1000 µs), 108.7 V clamping voltage at 100 A surge current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMB10J5.0HE3/5B datasheet, SMB10J5.0HE3/5B pinout, SMB10J5.0HE3/5B application, or SMB10J5.0HE3/5B equivalent, key selection criteria include clamping performance under 100 A surge, unidirectional polarity with cathode band marking, RoHS-compliant matte tin terminals, MSL Level 1 reflow compatibility, and thermal resistance (RθJA = 72 °C/W) for PCB layout validation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1000 MΩ leakage at 5.0 V), but triggers into low-impedance conduction when transient voltage exceeds VBR (6.4–7.07 V). Its glass-passivated junction ensures stable breakdown and fast response (<1 ns), while the DO-214AA package supports automated placement and meets UL 94 V-0 flammability rating.
The device is rated for -55 °C to +150 °C operating junction temperature, with 100 A non-repetitive forward surge capability (8.3 ms half-sine) and 100 W steady-state power dissipation. Its 20 °C/W junction-to-lead thermal resistance enables effective heat transfer to copper pads, and the HE3 suffix confirms AEC-Q101 qualification and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin for 5 V rail protection. |
| VBR (min/max) | 6.4 V / 7.07 V at 10 mA - Verified breakdown threshold range; ensures reliable triggering above system nominal voltage with process tolerance. |
| VC @ IPPM | 9.2 V at 108.7 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream ICs during ESD/EFT events. |
| PPPM | 1000 W - Peak pulse power handling (10/1000 µs waveform); defines energy absorption capacity for automotive load-dump or ISO 7637-2 pulses. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments and industrial enclosures. |
| RθJA | 72 °C/W - Junction-to-ambient thermal resistance on 5.0 mm × 5.0 mm copper pads; informs minimum pad area and airflow requirements. |
| Polarity | Unidirectional - Cathode marked with band; blocks reverse current during normal operation and clamps positive transients only. |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode identified by color band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry (during clamping) | Connected to protected line (e.g., 5 V rail); conducts surge current toward ground when VAK > VBR. |
| Cathode | Forward current exit / reference node | Marked with band; tied to system ground or low-impedance return path; establishes clamping reference and defines unidirectional behavior. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, body electronics, and infotainment systems per stress test requirements. |
| Glass passivated junction | Ensures stable VBR over lifetime and temperature, minimizes parameter drift, and improves reliability in humid or high-bias environments. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk. |
| Low incremental surge resistance | Enables tighter clamping (VC = 9.2 V @ 108.7 A) versus competing TVS devices, reducing voltage overshoot on protected nodes. |
| UL 94 V-0 molding compound | Self-extinguishing encapsulation material prevents flame propagation in safety-critical assemblies and meets IPC standards. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ5.0A-E3/5B | Same DO-214AA package and 5.0 V VWM, but rated for 600 W PPPM (vs. 1000 W); lower IPPM (64.9 A vs. 108.7 A). | Not AEC-Q101 qualified; suitable for commercial-grade consumer or industrial equipment where automotive reliability is not required. | Select when cost sensitivity outweighs surge margin, and AEC-Q101 certification is unnecessary. |
| SMCJ5.0AHE3/5B | DO-214AB (SMC) package with higher 1500 W PPPM and 170 A IPPM; larger footprint (7.11 × 6.22 mm vs. 4.57 × 3.94 mm) and RθJA = 35 °C/W. | Higher power handling suits 24 V systems or primary-stage protection; requires more PCB area and different thermal design. | Choose for applications needing >1000 W surge capacity or where board space allows larger SMC package. |
Compared with SMBJ5.0A-E3/5B, SMB10J5.0HE3/5B delivers 67% higher peak power and automotive qualification; versus SMCJ5.0AHE3/5B, it offers 35% smaller footprint and adequate clamping for secondary-side 5 V rail protection without over-engineering.

FAQ
What is the clamping voltage of SMB10J5.0HE3/5B at its rated peak pulse current?
The SMB10J5.0HE3/5B has a maximum clamping voltage (VC) of 9.2 V when subjected to its peak pulse current (IPPM) of 108.7 A under the standard 10/1000 µs waveform. This value is measured at TJ = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events, ensuring downstream ICs remain within safe operating margins.
Is SMB10J5.0HE3/5B suitable for automotive applications?
Yes, SMB10J5.0HE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, -55 °C to +150 °C operating range, and validated surge performance-meets requirements for engine control units, body electronics, and ADAS subsystems per ISO 7637-2 and ISO 16750-2 standards.
What does the "HE3" suffix indicate in SMB10J5.0HE3/5B?
The "HE3" suffix in SMB10J5.0HE3/5B denotes two critical attributes: RoHS-compliance (E3) and AEC-Q101 qualification (H), plus JESD 201 Class 2 whisker resistance. This distinguishes it from commercial-grade "E3" variants and confirms suitability for automotive and high-reliability industrial deployments where long-term interconnect integrity is essential.
How does the DO-214AA package of SMB10J5.0HE3/5B affect thermal performance?
The DO-214AA (SMB) package of SMB10J5.0HE3/5B delivers a typical junction-to-ambient thermal resistance (RθJA) of 72 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. This value guides PCB layout-underscoring the need for adequate copper area and thermal vias-to maintain junction temperature below 150 °C during repeated surge events or elevated ambient conditions.
Can SMB10J5.0HE3/5B be used in bidirectional signal line protection?
No, SMB10J5.0HE3/5B is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional signal line protection (e.g., RS-485, CAN bus), a bi-directional variant such as SMB8J5.0CAHE3/5B must be selected instead, as SMB10J5.0HE3/5B only clamps positive transients relative to ground and conducts reverse current beyond its VWM rating.
